Foreword

au l Las eau p roposes tw o re late d ideas: th e first is th at of "graphic th inking"; th e second is gra p hic thin king as a de vice for com m uni­ cati on bet w een the de signe r and the designed for. Th e follow ing brief remarks are addressed to the relati onship betw een the two ideas.

P

d irect th e ac tions of others and wh o co m m un ica te their de cision s to th ose w ho wo rk thro ugh dr aw ings ma de by d raft sm en . Design ing, as a separate task , has co me in to being . Th e professional designer, th e profession al draftsman, and the as sem bly lin e occ ur simultan eously as related phen omena .

Histor ica lly, buildi ng d es ign was not so ind iffer­ eh t to human w ell-being that "com m un ication with the peopl e" becam e an issue until th e ac t of draw in g wa s divided into tw o sp ec ialized activities. The first wa s design drawi ng, in w hic h th e design er exp res sed h is or h er ideas. Th e seco nd was d raft in g used to in struct the builder.

This all occ urred some tim e ago, bu t the m om en ­ tum of the ch ange fr om craftsm an ship to draftsm an­ sh ip , broug h t abou t by the pe culiar form of in d ustrialization we have ch osen to adopt , persists. It now exte nd s to the division of labor in th e design er 's office. Th e build ing of gr eat bu ildings is no longer the cre ation of m aster cr aftsmen led by a m as ter builder but of archite ctural offi ces organized along the lines of in dus tri al production . The task of th e ar ch itec t has been divided and subdivided in to an as sembly line of designer, con str u ct ion m anager, in ter ior desi gner, decora tor , struc tural, elec tri cal, and m ech anical engi­ neers, an d d raft sm en . Design dec isions onc e made by th e designer on the drawing board ar e now made by th e p rogram m er on comput er p rintou ts.

De sign d rawing began as and remains a m eans of gen era tin g ideas, for ta ppi ng in itial con cepts to be sorted out and developed , or simply as an enjoyable ac tivi ty. Dra ftin g is an eigh t-h our ta sk p er forme d dai ly, fill ing shee ts of paper w ith precise lines d ic­ tated by ot hers. Long ago, when the w ork of individual craftsme n beca m e larger and m ore com plex, wh en a cathedr al rather than a chair w as to be designed , dimension s had to be esta blis he d so th at th e work of a single cra ftsm an co u ld be coo rd ina te d with th e w ork of m any. Drawing w as introdu ced as a cr eativ e device for plan n ing wo rk. • Cr aft sm en ha ve a lways u sed drawings to hel p th em visua lize the ir ideas as th ey made adj ustments in th e continu ous p ro cess of fitt in g parts tog eth er. Dr awing under these cond itions is in sep arabl e fr om the w ork itself. Som e historian s say th at th e w orking draw in gs for the gr eat church es of the tw elfth and thirteenth centuries w er e d rawn on boards that w er e later nai led int o the const ruct ion . But drawing also has other purposes. Th e d ivisi on of labor in cr eases product iv ity. Art ifacts requ iri ng several wee ks of wo rk by a sing le sk illed cra ftsman are d ivid ed in to sm all er st and ardi zed w ork tasks. Pr oduc tion is increa sed as skill is elimina te d. The cr aftsm an' s expression of m at eria l, design sen se , and sket ches are bani sh ed fr om the wo rkplace . Drawings an d specificatio ns pre de te rm ine a ll fac et s of t he w ork. Design decision s are give n to a new class of wo rk­ m en who do not w ork w ith the mat er ial but in st ead

There are those of us w ho believe that indu strial­ ization cou ld have been ach ieved w ith out dest roy ing the crafts m an 's skill, love, and respect for material and the joy of building. We find it even less desirable tha t the jo y of creativity a nd grap hic thi nking that acco mpanies th at ac tivity should leave th e design er 's offi ce for the m em ory ban k of a comp uter. The built world and artifacts around us are ev i­ den ce of the alm os t fat al erro r of basing design on the mindl ess w ork of the ass embly line . To devel op pro­ gr amming and operat ion al resea rc h based on m ind­ less design would be to con tin ue a dis astrous hist oric continu um . Graphic th in king is of course necessa ry to help rej uven ate a mo ri bund design sy stem. But com muni ­ ca tion "w ith th e pe ople " is n ot enough . Cr ea tiv ity itself m ust be share d , and sha red wi th everyone from do w el kn ock er to "Liebe r Meis ter." The nee d fo r grap hic thinking is grea t, bu t it is greater on th e w or kben ch es of the as sem bly lin es at Riv er Rouge th an on the desks of the chi ef designers of Skid m ore, Ow ings & Merrill. - F ORREST W ILSON,

Preface to the First Edition n the fall of 1976, while participating in a discus­ sion group on design communication at the U niversity of W isconsin-Milwaukee, I had the occ asion to mention my book Graphic Problem Solving. Essentially, that book was an attempt at con­ vincing architects to apply their freehand concept­ gath ering skills to nontraditional problems dealing more with the processes than the products of archi­ tecture. During the discussion , Fuller Moore stated that the graphi c skills I had assumed to be part of arch itectural training were being neglected in the schools and that a more basic book on drawing in support of thinking was needed. Soon after, I had th e chance to talk to several architects about the sketches th ey use to d evelop designs in con trast to the "fin ­ ished drawings th ey use in p resen tations." Most cre­ ative architects had de veloped impressive freehand sketching sk ills and felt comfortable sketching while thinking . Some architects d r ew observations or design ideas in sm all sketchbooks they carried with them at all times. Both the architects and th e educa­ tors I interviewed expressed concern over the appar­ en t la ck of freehand graphic skills in pe op le now entering the profession.

I

As I began to collect materials for this book , 1 wondered about the re levance of sketching in archi­ tecture. Could sketching be better applied to design­ ing as p racticed tod ay ? The answer to this qu estion depends on an exami nation of the present challenges to architectur al design : 1 . To be more respon sive to needs, a problem-solv­ ing process. 2. To be m ore scientific, more reliable, or pr'> dict able. The response to these challenges was su ggest ed by Heinz Von Foerster: ...the language of arch itecture is conn otative lan­ guage because its in tent is to initiate interpretation .

•

The crea tive architectural space begets crea tivity, new insights, new cho ices. It is a ca talyst for cogni­ tion . This suggests an ethical imperative that applies not only to architects but also to anyone who acts on that imperative. A ct always so as to: inc rease, enlarge, enhance the number of choices. I

Relating these ideas to the challenges en um erated earl ier, I see two correspo nding imperatives: 1. Ar chitects sh ou ld solve p roblem s wi th peopl e in st ea d of for them by helping them under stand their ne eds and the choices of designs th at me et those ne eds. This is d one by bringing th ose who use the build ings int o the process of de sig ning those bu ild ing s. 2. Archi tect s m us t better u n ders tand sc ience and how mu ch it has in common with architec tur e. Jacob Bronowski pointed out th at the crea tive sci­ entist is more in teres ted in exploring and exp and­ ing id eas th an in es tablishing fixed "truths." The unique qu al ity of human beings lies in th e increase rather than the decrease of diversity. Within this context , sketches can contribu te to de sign, first by facilitat ing the exploration and d iver­ sity of ea ch designer's th in kin g. Second, sket che s can help open up the desi gn process by developing com ­ m unicat ion with people instead of presentin g con clu­ sions to people. Th e not ion of graphic think ing gr ew out of the recognition that sketchi ng or drawing can and should support the de signe r 's thinking. I re ali ze that som e readers w oul d be more comfo rtable w ith a bo ok about either thi nkin g or drawi ng , but I felt it was cri t­ ical to deal w ith th eir inte raction . Pu lling th em apart se emed to be like tr ying to u nde rs tan d ho w a fish swims by studying th e fish and the water sepa rately. I hope you will be able to bear w ith the rough spots in this book and find som e th in gs that wi ll help in your work.

Man y of th em als o pro­ vided sketches to illustrate th e text. Th eir ded ication to creativity in arch itecture, enthusiasm for dr aw ing, and co m me nts abou t their de sign p rocesses were a gre at he lp and inspirat ion for my work. Among the se architec ts, I am especiall y indeb ted to David Stieg litz, T hom as Bee by, Mor se Pay ne , Thomas La rso n, Mich ae l Ge b har t, Rom a ldo G iurgola , Jam es Tice , Nor m a n Crow e, Harry Egin k , Kir by Lock ard , and Steven and Cathi H ouse.

Figure 1-4 By Alvar Aalto.

Th er e ha s, of cours e., been an int ense in te rest in ar ch itec ts ' drawings re kindled by exhibits lik e the Beaux-Arts and 200 Years of Am erican Architectural Dr aw ings. But th e emphasis is mo stl y on com m uni­ cation of the final fixed product , and these pres enta­ tion drawin gs tell us p ractica lly nothing about the w ay in w h ich the b uildin gs were designed. The think in g sketches ar e necess ary to understand the step -by -step proc es s. Yet ev en when the thinking sketch es ar e avai la ble , as in the do cuments of the work of LeCorbusier, they ar e usually overlooked in favo r of th e renderin gs or photos of the finished w ork. We ar e ju st beginnin g to appreciate th e impor­ tance LeCorb usier pl aced on sketches. As Geoffrey Broad bent no te s, "All the internal harmony of the work is in th e drawin gs.. .. It is incredible that artists today shoul d be in di ffer en t (even ho stile) to th is prime m over, this' sca ffolding' of th e project. "l

Among mod ern arc hitects, Alvar Aalto has left us proba bly one of th e best models of th e gra p h ic think­ in g tradition. His sket ch es are rapid and divers e; they def tly pr obe th e s ubject. Hand, eye , a nd mi nd are int en sely concentra ted . The sketc hes record th e level of develop men t , profi ciency, an d clari ty of Aalto ' s ide as. There are m any other architect s w hose work we can turn to , particul arly here in the United States, whe re w e are exp eriencing a resurgen ce of ske tching. Their draw ing s ar e inventive, diverse, and p rov oca­ tive. Whethe r they are m akin g notes in a sketchbook or turning over con ce pt s in th e design studio , th ese cre ative design ers are looking for som et hing specia l over and above solving the design pro bl em , like the gourmet w ho is lookin g fo r somethin g more than food .

VISUALTHINKING The study of visual thin king has developed in maj or pa rt fr om the st udy of cr ea tivity wi thin the field of p sycho logy. Th e w ork of Rudolp h Arn h eim in th e psychology of art has been particularly signi fica nt . In his book , Visual Think ing, he laid a basic fram ew ork fo r r esearch by dis solv ing the artificial barrier bet w een th in king an d the ac tion of the se nses. "By cogn itive , I mean all m enta l op erations invo lve d in

re ce ivin g, sto ri n g, an d processing of in for m ation: se n sory p erce ption , m em ory, th in king , learn in g.'" T his w as a n ew w ay of und erstand ing p er cep tion , namely, an int egration of mi nd and sen ses ; th e focu s of th e study of creativity sh ifts fr om the mi nd or th e senses to the in terac tion of bo th. Vis ual th in kin g is th erefore a form of th inking that uses the products of vision -seeing, im agining, an d drawi ng. Wi thi n th e context of de sign ing, th e focu s of this book is on th e third p rod uct of vision, d raw ings or ske tches. When th in k ing becom es ex ternalized in th e form of a sketched im age , it can be sa id to have become grap hic. There ar e stro ng indications that thin kin g in any fie ld is greatly enha nced by th e us e of more than on e sense, as in doing w hile seeing. Although this book 's foc u s is on arch itectu ra l design, it is my hope tha t other readers w ill find the exp lanation s and exa mples usef ul. T he long history of a rc hitec tura l design has p rod uced a grea t w ealt h of graphic tech niqu es and imagery in response to hi gh ly complex, com prehen­ sive, quantita tive-qual itative prob lems. Tod ay, arc hi­

te ct ura l desi gn attem pts to deal w ith our total man -made environ m ent , a prob lem that is p ers onal and pressing for everyone . The graphic thinking tools used by archi tec ts to solve p rob lem s of intera ction, conflict, efficie ncy, and aesthetic s in build ings have now become im portant to all part s of society w ith its own in cr easingly complex problem s.

GRAPHIC THINKING AS A COMMUNICATION PROCESS The proc ess of graphic th inking ca n be seen as a con­ versa tion wi th ourse lves in w hich we comm unicate w ith sketches. Th e com mun ication p ro cess involves th e sketched image on th e paper, th e eye, the brain, an d the hand. How can this ap parently closed ne t­ w ork gen erate ideas th at ar e not already in the br ai n? Part of the answer lies in th e def inition of an ide a . Th e so-called new id eas are really a new way of look­ ing at and com bi ning old ide as. All ide as can be said to be co n n ected; the t h in king p rocess re shuffles ideas, focu ses on pa rts, and re com bines th em . In th e d iagra m of th e graph ic-th in ki ng p rocess , all four pa rts-eye, brain , hand , a nd ske tch - ha ve the capa­ bility to add, subtract, or mo dify the information tha t is being passed th rou gh th e com m unica tion loop . The eye, assisted by pe rc ep tion, can select a foca l p oint and screen ou t oth er in form at ion . We can re ad ily accep t th at the brain ca n add in formation . Bu t th e oth er two parts, han d and sketch , are also important to th e p roce ss. A differ en ce oft en exists betw een w hat we in tend to draw and w ha t act uall y is draw n . Draw ing ability, m aterials, and our m ood ca n all be sources of change. And yes , even the image on pa p er is su bjec t to change. Differences in ligh t in tensity and angle, the size and d istance of th e image from the eye, reflect ivity of pap er, an d transp are n cy of m edia all op en up new possibilities. The potential of graphic thinking lies in the con­ tin uou s cycling of inform ati on- laden im ages from pa pe r to eye to brain to hand and back to the pap er. Th eoreticall y, t he m ore often the informa tio n is pas sed aroun d the loop , th e m ore oppor tun ities for change. In th e sequen ce of im ages opp osite, for exam­ ple, I started with a sketc h of car toon-l ike bu bble s to

Introduction

rep re sent spaces in a hou se tha t is ye t to be designed. Dep end ing on my exp erience, int er est s, and what I am tr yin g to do , I w ill see ce rt ain th ings in the sketch an d ign or e oth ers . T he resulting perce pt u al im age seg r ega tes sp ec ial-u se sp aces, th e livi n g roo m an d kitchen , fr om several other mo re pr iva te or support spaces. Next, I form a m ental im age to further organ­ ize th e spaces and give th em or ien ta tion bas ed on what I already kn ow about th e site or a south ern exp osur e for th e living room and ki tchen. Wh en this m en ta l im age is tr a nsferred to pap er once mo re , it goe s th rough yet another ch ange in which the special sp aces begi n to ta ke on distinctive forms. T his is, of cours e, an overs im p lification of th e proce ss. Grap hic thi nkin g, like visu al com mu ni catio n w ith th e rea l world, is a con ti n uous process. In for m ation is sim ultan eously dar ting a ll over th e ne tw ork. W hen graphic th inkin g is mo st active , it is similar to wa tching a fantastic array of firew orks and loo king for the one yo u rea lly enjoy. Not on ly is it pro d uctive, it is fun . In Arnh eim 's w ords, "Far from b ei n g a passive mech an is m of regis trati on li ke the p ho togr ap hi c cam era , our vis ua l appa ra tu s co pes w ith th e in coming im ages in ac tive str uggle;" Visu al thin kin g an d visual per ception cannot be se parated from ot her types of th inking or percept ion . Ver bal thinking, for example, adds mo re to the idea of a ki tchen or livin g roo m w ith su ch q ua lifiers as brigh t, ope n , or co m fort able . Obvio u sly, grap h ic thin king is n ot all yo u need to k now in or der to solve p ro ble m s or thi n k crea tivel y, bu t it ca n be a ba sic tool. Grap hic thinking ca n op en up chan nels of com­ m uni ca tion w ith ou rse lve s and th ose p eople w ith w hom we work. The sketches generated are im po r­ tan t because they sh ow ho w we are th inking about a problem, not ju st w ha t we th ink abo ut it.

Grap h ic th in king takes advantage of the po w er of v isual percep tion by making vis ual images exte rn al a nd exp licit. By p u tti ng th em on paper, we give vis ua l images objectivity outs id e our brain , an existen ce of th ei r ow n over tim e. As Ro b er t M cKim p oi n ts out , gra phic th in king, as externalized th inkin g: has several advantages over internalized thought. First, direct sensory involvement wi th materials pro­ vides sen sory nourishment-litera lly 'food for thought.' Second, thin k ing by manipulating an actual structure permits serendipity-the hap py accident, the unexpected discovery . Third, thinking in the direct context of sight, touch, an d mo tion engenders a sense of im mediacy, actuality, and action. Finally, the ex terna lized thoug ht structure provides an object for critical contemplation as well as a visible form tha t can be shared with a colleague."

To the person w ho m ust reg u larly se ek n ew solu ­ tion s to problems, who must th ink creatively, the se q ua lities of im med ia cy, stimu la tio n, acci de n t , a nd con templa tion are very importa nt. To th ese q ualities I would add one more sp ecia l att r ib ute of graph ic th in k in g, sim u lta neity.

In troduction

EFFECTIVE COMMUNICATION A st a nd ard story th at m any archit ects del ight in tell in g de scribes h ow the m ost ba sic co nc ept fo r a multim illion -doll ar project was first scribbled on the ba ck of a restauran t na p kin . I have wo nd er ed w hy both th e telle r and th e listener alw ays se em to derive a m use me nt from s uc h a sto ry. Perhaps the story restores confidence in the strength of the ind ividual de signe r, or m ay be it is the incongruity that de cision s on suc h im por ta nt matters ar e being made in suc h a re laxed , cas ua l m ann er. Viewing th is story in the con ­ text of gr aphic thinking, it is not at all sur prising th at in spired , inven tiv e thi n kin g sho ul d ta ke place at a resta ura nt tabl e. Not on ly are th e eyes, m inds, and han ds of at leas t tw o person s interacting with th e im ages on th e napk in , but als o they ar e further stim­ ulated by con versat ion . Besi des , these pe rso ns a re separa ted fr om th eir day-to-day wo rk prob lems ; th ey are rel axing in a pleasant at m osphere, and with th e co nsu mptio n of good food , th eir level of anxiety is significan tly recfuced. They ar e op en , ready, prepared for d iscovery ; ind eed , it would be surprising onl y if the most cr eative ideas w ere n ot born in this setting. To be effective commun ica tors, arc hitec ts m ust: 1. Un d ers ta nd the bas ic elem e nt s of co mmun ica ­

tion-th e com m unicator, th e receiver or aud ience , the m ed ium , and the context-e-and their ro le in effect iven ess. 2. Develop a gra p hic language fr om w h ich to dr aw the m ost effective sketch es for specifi c com m uni­ cati on tasks. 1 . Never take for gra nte d th e process of comm un ica ­ tion and be w illing to tak e the time to examin e their effe ctiveness. Basic co m m unica tion th eo ry stresses th e com m u­ nication loop betw een the com munica to r or sender and the receiver in order to att ain maximum effec­ tiveness. Response fr om th e audienc e is essential to a speaker wh o wants to get his m es sa ge across. The inform ation com ing from the receiver is as im porta nt as what th e sender, th e archit ect , transmits. And so we m ust p ay very clo se atte n tio n to th ose p ers ons with whom we h op e to comm un ica te . The bes t app ro ac h is to try to p la ce one se lf in th eir shoes . What ar e th ey expecting? Wha t are th eir co nce rns? Equ ally important , w e sho uld be awa re of our m ot i­ vations and conce rns. Do w e h ave an unconscious or hi dden agenda?

As furth er chap ters r ev iew th e m any w ay s gr aphi c thin ki ng is us ed in the practice of arch itec­ ture, it is critical to remember that individ uals ca nnot really be cut off from the ir environm ent or th eir soci­ et y. The grap hic thinking of on e person thrives in the presence of goo d com pa ny and a su pportive atmos­ phere. See k both enthusias tically. Altho ugh th e m edium with w hich this book dea ls is principally fre ehand sketches, th e basic me thods are ap pli cable to many graphic m ed ia. But each specific m ed ium has so m e u niq ue characte ris tics th at have sp ecia l effec ts on co m m un ication. Expe rim enta tion wi th differ ent media is th e fast est route to using them eff ect ively. Although there are books on th e us e of th ese m ed ia, th ere is no su bstitute for practi ce, becau se w e all have different n eeds and abiliti es. The context for com m u n icatio n includes su ch th ings as location , time, duration , weather, and type of space, w ha t took place be fore the com mu nic ation, w hat will ta ke place after. We may be able to con trol some of the se context variables, but we ca nnot afford to igno re th em .

THE ROLE OF GRAPHICTHINKING IN ARCHITECTURE

their p ur pose is to exp lain to other pe opl e the prod­ u ct s of o ur th in kin g, the co n cl us io n s. Tra in in g in ar ch itectu ral sch ool s h as been primarily gear ed tow ar d the at ta in ment of finished presen tation skills, whil e in architectural offi ces, th e emphasis has been on turning out working drawings that clearly pr es ent the necessary di rectives for the contractors.

To realize the pot ential of gra phic th in king in ar chi ­ tecture, w e m ust unders tand to day 's prevailing atti­ tu de s on th e design process and the use of d raw ings in that pro cess. In th e ea rly 1960s, A. S. Levens w as ab le to write w ith conf id ence tha t: One source of confusion in thi nkin g ab out design is the tendency to identify design wi th one of its lan­ guages, drawing. T his fallacy is sim ilar to th e confu­ sion w hich would result if musical composition were to be identi fied w ith the w riting of not es on a sta ff of five lines. Design, lik e m usical composition, is done essentially in the m ind an d the making of drawings or wri ting of no tes is a recording process. 8

Today, w e hav e broade r conc ep ts of h ow an d wher e design takes place, bu t drawings are st ill nor­ ma lly th ought of as sim ply representations of ideas;

Introduction

In response to Levens' ana logy, graphic th in king treats drawings more like a piano than a score sheet. Like com position, desig n is poss ib le witho ut an instrum en t to provid e feedback, bu t for m ost des ign­ ers this is not very produ ct ive. Design thi nking and design comm u nica ti on sh ould be interactive; t his implies n ew roles for graph ics. As w e anticipate th e p oten tial of comp uters and other evol vi ng comm uni­ cation te ch nol ogies , the con cept of feedbac k wi ll be key to effective use of media .

ORGANIZATION OF THE BOOK

bu ild ing could get designing started. Distortion of an eleva tion might re veal a new approach to de tailing. Rever sal of a process diagram m ight suggest a mo d ifi­ ca tio n of the bu ilding program.

The first m ajor sec tion of th e book is devo ted to the basic grap hic th inking ski lls of repre sen tation and con­ ception . Th e section incl udes four chapters dealing with drawi ng, the use of conventions, abstraction, and expression . My aim is to pro mo te an awareness of the rich variety of graph ic tools availab le for adding pro­ ductivi ty and enjoy me n t to th in king activities.

Th e third section of the book considers grap hic th inking as communi cat ion in three des ign cont exts: individual, tea m, and public . The em p hasis is on better communication so that ideas can be sha red.

Th e se cond sec tio n of th e boo k addresses the applicat ion of grap hic thin ki ng to de sign processes. Its four chapters discuss analysis, ex plora tion, discov­ ery, and verificat ion . Although there are some obvious applicat ions of thes e use s to a n u m ber of design pr ocess m odels, I have purposely avo ided promoting a spec ific design process. O ne of the problems wi th design p roce ss models is th eir accept ance in too sim­ plistic a way; types of th ink ing or behavior are cate ­ gor ized, and the int ermeshi ng of processe s and ide as is ignored . Instead of cat egories, we ne ed flex ibility. Ma nip u lat ion of gra p hic images, for examp le, might be used at ma ny stages of de signi ng . I still wo uld not attemp t to guess w here it wo uld be ha ndy for a spe­ cific p roj ect . Man ip ulati on of the ste reotyp es for a

The approach is eclectic ra ther than dis cr imi nating, inclu­ sive no t excl usive, expectan t n ot co n clu sive. T he intent is not simpl y to describ e examples bu t to con­ vey th e excitem en t of grap hic th ink in g and even m ake it contagi ou s. We all have sp ecial , uni qu e ca p acities for th inkin g, w hich , if un locked , co u ld make grea t contributions to th e solu tion of problems we face. Arn heim emphas izes tha t "Every gre a t art ist gives bi rth to a ne w un iverse, in w hi ch the fam iliar things look th e w ay th ey have n ever before looked to anyone.

BASIC SKILLS

hiS chapte r's focus is on th e ba sic represen ta­ tion skills help ful to graphic thinking m eth ods as prese n te d in th e rem ainde r of thi s book . De ve loping freeha nd draw ing skills is n eces­ sary to th e att a in m en t of graphic thinking an d per­ ceptual skills. Some might say, "I really admir e good draw ings and those designers wh o have a qui ck hand , but 1 hav e accepted th e fact tha t 1 w ill never be th at good ." Bun k! It ju st is not SO l Anyone can learn to d raw we ll. If you don 't believe m e, ta ke th e time to tal k to people w ho draw very wel l. You w ill find that their fir st drawi ngs w ere ten tative . Th ey probably took every oppo rtunity to draw. With tim e and hard w ork , th ey gr ad ua lly im p roved and n ever regretted th e eff ort th ey made.

T

The re are tw o impo rtant co ndi ti on s to keep in m ind wh en trying to develop any skill : 1 . Skill comes w ith re petition.

2. The surest w ay to p rac ti ce an y s kill is to enjo y w hat you ar e doing. Because of th e he av y em phas is on ra tionalization in formal ed uca tio n, many people mis tak enly th ink that th ey can master a ski ll, suc h as drawing, sim ply by understanding concepts. Con cepts ar e helpful. but pr actice is esse ntia l. The orchestra conduc tor Artie Shaw on ce explai ned w hy he refu sed all requ ests by parents to audition the ir childr en. He felt that th e wo rst thing you can do to a talented child is to tell him he has talent. Th e greats in the m us ic bu siness, rega rdless of na tu ral talent, became successful through hard work an d a com m it­ m ent to their cr aft. They believed in themselv es but knew the y would have to stru ggle to prove th emselves to ot hers. The focus of energy, sense of comp etition , and year s of hard work are essential to becom ing a fine m usicran .

The kn owled ge t ha t d raw ing a nd t hin king are im p ort a n t to ar chitecture is not sufficien t. Nat ura l draw in g talent is no t enoug h . To sus ta in th e n eces­ sary lifeti m e effort of learn ing and p erfecting gra p hic th in kin g, w e nee d to find p leasure in drawing an d think in g. We must be challen ged to do it be tter than those arc hitec ts w e ad m ire do. Morse Payne of Th e Arch itec ts Collaborat ive once noted th e infl uence of Ralp h Raps in on many talented designers: "To w at ch Ralph kn ock out one of his beaut ifu l per sp ectives in fifte en min utes w as tru ly ins piring. It set a goal for us that was very challenging." 1 For tunately, t here is still a lot of respect wit hin th e architec tura l profession for high-quali ty d raw ing. Th e person who ca n expres s hims elf b ot h graphicall y a nd verba lly on an impromptu basis is highly ' valued . W hen hiri ng, off ices oft en loo k for a bi li ty to commun icate ove r ability to be origina l. They know that your ability to develop ideas w ith th em is muc h m or e important in the long run than the idea tha t yo u in itially bri ng to them. It is possi ble to be a n architec t w ithout having w ell-developed grap hic thi nking skills. A barber or a bartender ca n surely cut hair or serve d rinks withou t being able to carry on a conversation . But th e job is a lot ea sier if you enjoy tal king w ith people, an d you will prob ably do more business. 1 believe that grap hic thinking can m ak e design m or e enjoyable and more eff ective.

Four types of basic ski lls sup po rt grap hic th in k­ ing: observa tion , pe rc ep tion , d iscr im ina tion, and imagin ation . Although these are considered to be pr i­ marily th in king sk ills , in this ch apter 1 have tr ied to show how gr aph ic mean s may be used to pro mo te th ese sk ills an d att ain a funda m ental inte gra tion of gra p hics a nd th in ki ng . The se q uen ce in w h ich the skills are add ressed reflects my ass umption th at each thi nking skill sup ports those th a t foll ow.

his cha p ter' s focus is on the basic represe nta­ tion skills helpful to gra p h ic th in king m etho ds as p rese n ted in th e rema inder of th is bo ok . Develop ing free hand d raw ing skills is ne ces­ sary to th e atta inmen t of graphi c think ing and p er­ cep tual skills. Some m igh t say, "I really adm ire goo d d ra w ings a nd th ose desi gn er s wh o have a qui ck han d, bu t I have acce pt ed the fact th at I wi ll ne ver be th at good ." Bu n k! It jus t is not so! Anyone can learn to d raw well . If you don 't believe m e, take the time to ta lk to pe op le w ho dr aw very w ell. You w ill find that th eir first draw ings w ere ten ta tive . They p roba bly took every oppo rtu ni ty to draw. W ith time and hard wo r k, th ey gradually imp roved and never re grette d the effort th ey mad e.

T

T h er e a re tw o im por tan t con dition s to keep in mi nd when trying to develop any sk ill: 1. Skill co mes w it h rep etition . 2. Th e surest w ay to prac tice any s kil . is to en joy what you are d oi ng. Beca use of th e heavy em p has is on rationa lizati on in form al edu cati on, m any peop le mi staken ly think th at th ey ca n ma ster a skill , such as draw ing, simply by understandi ng co nc ep ts. Concepts are helpful, but practice is esse ntial. The orchestra conductor Artie Shaw on ce explained why he refused all requests by parents to au dit ion th eir child ren. He felt that th e wo rst thing you can do to a talented child is to tell him he has talent. Th e grea ts in the m usic bu siness, regardless of na tural talent , became successful th ro ugh hard work and a com m it­ m en t to their craft. They believed in themselves but knew the y would have to struggle to prove th em selves to oth ers. Th e focus of en ergy, se nse of competiti on, an d years of hard work are essential to becom ing a fine musician.

Th e know ledge th at d raw ing and t hi nk ing are imp or ta n t to a rchi tect ure is not sufficien t. Nat ura l d rawing talen t is not enou gh .

OBSE RVATION The thousands of students who pass through archi­ tectu ral schoo ls are us ua lly to ld th at they shou ld learn to sk et ch fr eeha nd and , to a cer tain degr ee, how . Rarely are they told w hat they sh ou ld ske tch or w hy. Draw ing cu bes and othe r still-life exercises ar e an att em p t to teach ske tching d ivorced from th in k­ ing. Mo st st uden ts fin d it bori ng, and it drive s some away from sketchi ng for the rest of th ei r lives. I pre­ fer to sta rt students with th e sket ching of exis tin g buildi ngs beca use : 1. The y ar e drawing subjects in wh ich th ey have a

basic in terest and are re ady to dis cuss. 2. T he eye an d m in d as well as the hand ar e involved ; percep tion becomes fine-tuned , and we begin to sor t out our vis ual experiences. 3. On e of th e best ways to learn about archi tectural design is to look close ly at existin g buildi ngs and spaces.

The clearest way to dem on str ate the valu e of fr ee­ hand sketchi ng for develop in g grap hic thinking skills is to compa re sketchi ng wi th ph otogra phy. Although a cam era is oft en a us eful or expedient too l, it lac ks many of the attributes of ske tche s. SKetches have the ab ility to rev eal our perc ept ion , th erefore giving more im po rtan ce to certain pa rts, wh ereas a photo shows everything wi th equal em phas is. In the sketch of the Spanish Steps in Rom e , the focu s is on the ch urc h , ell ipse, and step s as orga n izin g elem en ts for th e e ntire ext erior space. Th e sign ifican t im pact of the flowers in th e p hoto ha s been elim ina ted in the sketch . The abstra ction can be pushed furt her until there is on ly a pa ttern of light and dark, or we ca n fo cus on ly on certain det a ils, suc h as lamp posts or window s. This on e scen e alo ne is a d ict ion ary of urban design . But you do not have to wa it until you get to Rome to get s tarted ; th ere ar e lesso ns a ll around us. Becom e a prospec tor of ar chitect ural design ; build your ow n collec tion of good ideas whil e you learn to sket ch . It is a lot of fun.

T he most im port an t part of a sketch , the basic lin e draw ing, is also the mo st d ifficult skill to m as te r. It re quires a lot of practice, but I have a few suggestions th at sho uld help : 1. To help sha rp en th e se ns e of propo rtion need ed for ske tching , practi ce dr aw ing squares and th en rec­ tangles that are tw o or th ree times longer on one side th an on th e other. Now try to find squares in a scene yo u are ske tchi ng . (At th e beginn in g, th is co uld be don e w ith tracing pap er over a photograp h.) 2. Use a cross or a fra m e to get th e parts of th e sk etch in th eir prop er p lace, or maybe a p romi ne nt fea tur e of the scene or subjec t can act as an organizer for the ot her parts of the sketch . 3. ·Alth ough pen cil ca n certai n ly be us ed for sk etchi ng, I pref er fe lt -tip or in k pens b eca use the lines they prod uc e are simple and clear. If a line is in th e wrong place, it is qu ite ev ide n t. Because the lin e can not be eras ed , it m ust be redr aw n to get it right. This proc ess of rep et ition and checking against t he subjec t develops ski ll. Drawings th at are so light they ca n be ign ored or erased den y the design er the feed­ back essen tia l to his im pro vem ent. 4. To gai n mor e co nt r ol ov er line m a king, try so me sim ple exercises sim ilar to our "id le m om ent " doodl es . Th e sp irals, like tho se above , are d rawn fr om the ou ts id e toward the cen te r, both clockw ise and co unte rclockw ise . Try to m ake them as fas t as p ossib le without let tin g the lines touc h each ot her ; tr y to get th e lines close to each othe r. Stra ight hatch­ in g can be done in several directi ons , always striv ing for consistency.

Tones Tones can be represen ted with differe nt den sities of hatching or com binations of cross-ha tching . The lines s ho u ld be p arallel and have eq ual spa ces between them . Always re m em ber that th e ma in purpose of the cross- ha tching is to ob tai n different levels of gray or dar kne ss . Use straight strokes as if you were pa inting the sur faces w ith a brush . Errati c or irreg ular lin es d raw att ention to th em and di stract th e e ye fr om m ore im po rtant thing s. There is no st r ict r ule for ap ply ing tones on a sket ch, bu t I ha ve some prefer­ enc es tha t se em to work well. Horizontal ha tch ing is used on horizontal surfaces, di ago na l hatch ing on vertical surfaces . Wh en two ve rti cal surfaces meet, the h at ching on on e is at a slig htly di ff eren t an gle from the hatching on the other surfac e.

App ly tones in a three-step process: 1 . Indicate any texture that appears in th e surface, such as the vertical boards on a barn . 2. If th e textur e in d ication does not prov ide the level of darkness of th e subject , add the necessary addi­ tional hatching over th e entire surface. 3 . No w app ly m ore ha tch in g w here any s had ow s fall. To show gradat ions of sha dow, add a su cces­ sio n of hatches at different angl es.

The refinement of ton es in a d raw ing is ach ieved by loo king carefully at th e su bjec t a nd by ge tt in g m or e control over t he consistency of the lines. Severa l alt ern ative techniqu es for ske tc hing in tones are illustr ated throughout th is bo ok . The one show n at t he ri ght ab ove is a ra pid me thod usin g ra n­ dom strokes.

PERCEPTION Many a rchitects have b ecome m et hodica l abo ut sketch and note taki ng. Gordon Cullen , the British illus trator and urban d es ign consult an t, had a m ajo r influe nce on the use of ana lyti ca l sket ches. His book Townscape' is a wond erful collec tion of visua l percep­ t ions of th e urba n e n v iro n me n t. Th e sketc he s a re clear and com p rehe nsive , im p ress ive ev ide nce of w ha t can be dis covered wi th gra p hic thinking. Using pl ans , sect io ns , and perspectives, th e sketches go beyond th e obvio us to uncover n ew percep tio ns . Tones ar e used to iden tify m ajor orga ni zers of sp ace. (In the book , many of th ese tones are achieved m ec hani cally, b u t th ey are easily rendered in sket ches by hatch ing wi th grease pe nci l or large felt­ tip markers.] The verba l ca tego ri zation of urban ph e­ nom ena th rough shor t titles helps to fix the visual p ercep t ions in our memori es; verbal and gra phic communications are working together. And these are

not complica ted sketches; th ey ar e w ithin th e poten­ tial of most designe rs , as show n in the ske tc hes oppo ­ site, w hich apply Cullen 's techn iq ues to th e ana lysis of a small midweste rn town . As Joh n Gund elfinger puts it :

A sk etchbook should be a personal diary of what interests you and not a collection of finished draw­ ings compiled to impress with weight and numb er. ..a finished on-the-spot drawin g...shouldn't be the rea­ son you go out, for the objective is drawing and not the drawing. I often learn more from drawings that don't work out, studying the unsuccessful attempts tc see where and why I went off ..can learn more than from a drawing where everything fell into place . The draw ings that succeed do so in some measure because of the failures I've learned from preceding it, and so certain pitfalls were unconsciously ignored while drawing. S

Visual-Mental Games An en te rtaining way to im p rove ha nd - eye - mind coord ination and promote an ability to visualize is to play some simple games. 1. Show a few people four or five cuto uts of sim ­ ple shapes arranged on a pi ece of paper (above , left ). Ou t of view of the ot hers, one p ers on m oves th e cut outs while verbally desc ribing the move. The oth­ ers attempt to d raw th e new ar ra nge me nt from the description . Th is is repeated a few tim es to see w ho can ke ep track of the pos ition of th e shape s. Aft er m aster ing th is exercise, have the persons draw ing try to form a men ta l picture of each new arrangem ent and then try to draw only th e final arran gemen t. In a sec ond version of this gam e, an object is su bstitu ted for the cut outs, an d it is ma n ip u late d , op ened , or taken apart. 2 . Form a circl e wi th a small gr ou p. Each pers on m akes a sim pl e sket ch a nd pa sses it to hi s righ t.

36

D raw ing

Everyone tr ies to copy the sketch he has received an d in turn pa sses th e copy to th e righ t. This contin ues unti l the fin al copy is passed to the creator of the ori g­ in al sketch . Then all sketches are ar ra nge d on a w all or table in the order they were made. This ga m e illu s­ trates th e distinctiven ess of individ ual visual p ercep­ tion (above, cen ter). 3. Doodles, usin g an arch itectural or de sign th eme, are another form of puzzle. He re, th e obj ec­ tive is to provide just enough clues so the subj ect is ob vious once the title is given (above, right) . There are many visual p uzzles that exer cise our visual per cept ion. Try some of those sh ow n opposite; look for more puzzles , or invent some of your ow n . In th e sketches opposite, an arbitrary diagram is given and the cha llenge is to use it as a parti for di fferent bu ild ings by seeing it as standing for a section or plan view for starters.

We mus t recognize tha t eve n wi th th e m ost sophisticated techniques drawings are not a full sub­ stitute for the ac tua l experience of a n a rch it ec tural e nv ironment. On the other hand, th e capac ity o f sketches as thinking tools extends well beyond wh at is act ually con ta in ed in the sketc hes. Draw ings, as representations, should be seen as ex tensions of th e persorus] who uses them to aid in thinking. As Ru do lf Arnheim says: The world of im ages does no t simply im prin t itse lf upon a fai thfully sensitive organ. Rathel; in looking at an object, we reach out for it. W ith an in visible finger we move through space around us, go out to distant places where things are foun d, touc h the m , catch them, scan their surfaces , trace their borders, explore their texture. It is an eminently act ive occu­ poti on.'

I find a great variation in the deg ree to whi ch architects rely on drawings to v isua lize designs. One probable explanation for this is experience in vis ua l­ izing and w ith the bui lding of th ese desig ns. For examp le, when architecture students look at a p la n view of a room, they likely see just an abstract di a­ gram, but some experienced arc hitects ca n vis ua lize a perspective view of the same room without having to draw it.

4 Abstraction

T he design process can be thou ght of as a series of tran sformations going from un certainty towa rds inform ation. The successive stages of the process are usu ally registe red by some kind of graphic model. In the final stages of the design process, designers use highly form alized gra ph ic languages such. as those provided by descriptive geometry. B ut this type of representation is hardly suita ble for the first stages, when designers lise quick ske tches and diagrams...It has been accep ted for years that becau se of the high level of abstraction of the ideas wh ich are ha ndled at the beginn ing of the design process, they mu st be expressed necessa rily by mean s of a rath er ambigu­ ous, loose graphic languag e-a private language w hich no one can properly understand excep t th e des igner himself .. the high level of abstraction of the inform ation which is handled mu st not prevent us from using a clea rly defi ned graphic language. Such a language would register the information exac tly at the level of abstraction it has, and it would facilitate com m unicat ion an d coopera tion among designe rs. I

T he re are ot her ways of draw ing "graph ic se n­ tenc es" ; three alter natives ar e show n here:

The grap hic language pr opose d here has gra m ma tical ru les compar ab le to thos e of ve rbal langu age. Th e d ia­ gram of the se ntence (Figur e 4-3a ) show s three basic parts: nou ns, ver bs, an d m od ifiers such as adjec tives, ad verbs, a nd p h rases. Nouns r epresent iden tities , verb s es ta blish re lations h ips betw een nouns, and the modifiers qualify or q uan tify the iden tities or the re la­ tionships betw een ident ities. In the grap h ic d iagram (Figure 4-3b), identities are shown as circl es, rela tion­ ships are show n as lin es, an d m od ifiers are show n by cha nge s in the cir cles or lines (heavier lines ind icate mor e importan t relation ship s and tones ind icat ing dif­ fer ence s in id en tities ). In th e sen tenc e d iagram , the verb shows a relat ionship that th e subject has to th e object: the d og ca ugh t the bo n e. T he lin e in th e graphic di agram is bi-directiona l; it says that the livin g room is co n nected to the kitchen and that the k itchen is con nec ted to the livi ng room . Th us the gr aphic d iagr am conta in s m any se n­ tences as : 1. Th e very im portan t liv ing room has a minor rela­ tions hip to th e garage (Figure 4-3c) . 2. The dini ng room must be con nected to th e special spaces , the kitchen and the deck (Figur e 4-3d ). 3. The fut ure gu esthouse w ill be related to the en try and indirectly to the pool (Figure 4-3e).

Abstraction

1. Position- An implied gri d is used to establish rela­ tion sh ips between id en tit ies; th e resulting orde r som et im es m a kes the di agra m easie r to read (Figur e 4-4a ). 2. Proximity- T he degree or in tensity of th e relation­ sh ips of ide n tities is ind ica ted by the re lative d is­ tan ces betw een th em. A sign ifica n t increase in d ista nc e can im ply that no re la tio nsh ip exists. Th is typ e of di agra m ha s m ore flex ibi lity than the p rec ed ing type (Figure 4-4b). 3. Similarity- Iden tities are gr ou ped by com mon character istics such as co lor or sha pe (Figure 4-4c ).

Th ese a lterna tives m ay also be comb ine d to form other gram m atical var iat ions (Figur e 4-4d), but ca re should be taken to retai n consistency. To com m u ni­ cat e clearly, the gra m ma tica l r ules shoul d be im m edi ­ ately ev id ent. According to Jerom e Bru ne r, "The bind ­ in g fact of m en tal life in child and adu lt alike is that there is a limi ted ca paci ty for p roces si ng infor m a­ tion - o ur sp an , as it is ca lled , ca n comprise si x or seven u nr elated items si m u lt an eously. G o beyond that a nd there is ov erl oad , con fusion , forge tting ." One of th e re as ons for ad op ting some basic gr amma t­ ical rules in gr ap hic diagrams is to avoid con fusion by red ucing the number of varia bles that have to be han­ dled at on e tim e.

Figure 4-4d Combination of "sentence" structu res,

One of the m ost usef ul q ual ities of graph ic com ­ mu nica tion is tha t in for m a tion can be tra nsm itte d and rece ive d on sever al leve ls simultaneously. Ar tists rec ogn ized this long ago. Successfu l paintings us ually appeal to the vie w er as ove ra ll compositions, rend er­ ings of de ta il, and tech niq ue w ith m edi a , just to nam e a few of t he le vels. These leve ls o f comm u ni cation ca n also be used to good advan tage in a grap hic d ia­ gram. T he ba s ic process for bu ild ing a d iagr a m (show n above) is as follow s: ' 1. Try to illust rat e the basic iden titi es and their re la­ tionsh ips in a ro ug h diagram . 2. Red uce th e d iagram to its simples t structure by ap plyin g ru les of graphic gram mar. 3. Mo d ify th e d iagram to indicate a second level of information , using tones or heavy lines . 4. Add other levels of in formation as tags attached to the basic d iag ram . 5. If the d iagram becomes too co mplica ted, br eak it into seg men ts by group ing or placing a bo unda ry arou nd id en tities.

This co nsistent set is ca lled a voca bulary .

Lite racy is achieve d ove r se ve ra l years of edu cation . Th e acq uisit ion of grap hic language is not a com m on comp one nt o f a general edu cation. In a for m a l sense it is m ore often a part of ed uc at ion in d es ign and a rt curr icul a . How ev e r, the re are som e grap hic "la ng uages " to wh ic h the ge neral pub lic is ex posed. Among th ose are in terna tional road sig ns , roa d map legend s, mu sic notat io n , and mathe matical symbols. Th e acc essib ility of gr ap hic la nguages is heav ily d epe nde nt on associat ions with fa mi lia r obj ec ts or expe riences .

Identities There a re a grea t n um ber of w ays to sy mbolize a n ide nti ty. The more common symbols are repres en ted here in ho rizontal rows. The iden tity of th ese d iffer ­ ent possible groups is achieved by contrast. Us ua lly a ll varia bles are held con st ant exce p t for on e. Th e n um ber in ea ch group is limi ted becau se m ost of us are un ab le to de al with m or e th an five or six vari a­ tions in on e grap hic di agram . Th e el ementary sy m ­ bols can be supplemented o r replac ed by numbers, letters, or othe r sy m bols. By jud ici ou sly com bi n in g differen t gro ups of sy m bols, it is po ssible to have sev­ era l levels of infor mation in a grap hic d iagram w ith­ out sacri ficing clarity. Someti me s ide n tities are best show n w ith a more te n tative q uali ty using d ott ed and irr egular lines. Later chap ter s further explain this less d efinite need .

cco rd in g to Go rd on Best , th e an al ys is of design p rob lems is fu n d a m e n ta l to d esign p rocess. "Practica l d esign probl ems are va r i­ ab le and idiosyncrat ic. Th ey ge ne ra te a vari­ e ty so great t hat it is n early im p ossibl e to describe suc h prob lems le t alone und e rstand th em . Despi te th is, practicing design er s must in terpret th ese prob­ lems if they ar e going to d eal with th em. ": Ar chitects must simplify problems, reduce th em to th ei r esse n­ tial elements. This is the process of abstraction , th e exposure of the underly ing structure or pattern of a whole system. As w e w ill see, gr ap h ic co m m u n ica­ tion is w ell su ited to th e ta s k of abs tracti on . T h e simu ltaneous view of th e ab stract ske tc hes keep s the whole structure of a syst em up fro n t.

A discussion of a system and its a nalysis is h elpful to u nd erstand the fun ct ion s of abstract s ke tches. De sig n prob lems are gener all y ca used by poor func­ tion or breakdown of a system. If I ca n' t ge t my ca r started on a winter morn in g, I know th e ca use could be a fro zen ga s lin e, a malfuncti on ing sta rte r, worn ­ ou t spark plugs, the d istributor, the battery, or ev e n an empty gas tank. A car is a sys te m of parts, a ll of wh ich must int eract properly for th e engine to start. The syste m extends bey ond th e car pa rts to includ e ro utin e maintenance, the manufacturer 's inspection of parts, keeping moisture out of gas sta tion storage tanks, an d m y check ing th e gas gauge regularly. To so lve the problem wi th th e car that does n ot sta r t, we must u nd erstand it as a n orga n ized sys te m . If the di s­ tribu tor is no t the cause of th e problem , no degree of inspection of the distributor can so lve the p robl em .

In d es ign, th is understanding of th e w hole syste m is re ferr ed to as holi sti c a na lys is. As Geo ffrey Broadbent put it : The whole must be subdivided if we are to analyze it.... If we choose the wrong kin d of subdivision, then the whole w ill be destroy ed, wh ereas other kinds of subdivision may throw its struc ture int o relief A ngya l con sid ers four way s of subdi viding a whole, such as a plant, an animal or som e ina nimat e object .

One could abstract distinguishable properties from it, such as size, shape, color; consistency and so on, which would rep resent an empirical app roach. Or one could divide the whole according to its st ructural art iculation ,'

Analysis

In design or p robl em solvin g, products, proc esses , beliefs, or other syste ms need to be represented in several ways, rangin g from concr ete to th e m ost abstract. In M cKim 's words, "Op eration s often r equir e im ag ery that is abstract a nd pa ttern -like. Whi ch is not to say that abstract im agery is m ore important than con cr ete. Rath er, abstract and con­ crete imagery are complem entary. The flexible visual thinker moves readily back and forth between the two. " 3 He suggeste d , "A w ay to obtain lit eracy and at th e same time to ac q uire la n guage flexib ility, is to learn how to use graphi c language to m ove thinking and exp res sion from abstract to concrete m eanings and ba ck.

Th e fun ct ions an d the re lationsh ip s between functions ar e ind icat ed , as w ell as the hier­ archy of these functi ons and re lationships. Th e majo r access points are clearl y visible. The "bubbles" have no po sitio na l significa nce because th e program do es not cont ain th at sort of information. If the relation ­ ship lin ks bet w een fun ctions ar e reta ined , th e bu b­ bles can be m ove d to several di fferent p ositions w ith­ out ch anging the bas ic in form atio n of the d iagram. Th e second d iagra m respo nds to site and climate inform ation , es tablishing both po sition and orien ta­ tio n of fun ctions with respect to each oth er and the si te. Na tural ligh t and heat , vi ew s, bu ild ing acces s, a nd zoni ng of fu nct ions are also consid ered . T he th ird d iagram reflects de cis ions on scale and shape of the sp ac es requ ired to ac com mod at e the program m ed functio ns. Here, consideration is given to function al nee ds and a p lanning gr id. In the fourth diag ram , spe­

(The t ra nsf or m ation s after t h e schematic d esign th at lead to the fin al bu ildi ng incl ude preliminary design , des ign development, con­ struction documents, and shop dr aw ing s.

ABSTRACTION APPLIED TOARCHITECTURAL DESIGN

Figu re 6-7b Misfit between need and context.

The re st of this chapter is based upon a mo re sophis­ ticat ed model of th e design process. The appli cation of th e tool s of gr aph ic abstractio n to arc hitectura l design is aide d by an und erst and ing of the structure of ar chitect ural design problems. H ors t Ritte l has identified three variables of th e typica l design prob ­ lem : 1. Performance var iables w h ich express d esired characteristics of the object under design, and in terms of which the object w ill be eva lua ted ("con ­ str uction cos t," "aesthe tic app eal ," "overall q ua l­ ity," and th e like). . 2 . Desi gn variables, which desc rib e th e possibilities of th e des ign er, his ranges of choice , his design varia bles ("height of ceiling," "shape of d oor kn ob," "type of heat ing ," and th e like ). 3. Context vari able s, which are th ose fac tors affec t­ ing the object to be des ign ed but no t controll ed by the design er ("land p rice, " "likel ih ood of ear th­ quakes," "type of eating habits," and so forth]."

A problem can be said to exis t w he n th ere is som e sor t of m isfit among these three variab les in an env i­ ro nm ent. Th e desi gn pr oblem is solved w he n , as in di ­ cat ed in the diagram , there is a sati sfac tory relation­ sh ip am ong n eed , co nt ext , and form .

Analysis

O n e effe ctive w ay of incre asing perception is th rough visua l analys is. T he em p hasis of a specific va riable such as scale or rhythm in a sketch can be abstracted fro m the co n text of the bu ildi ng. Sca le implies a relati onsh ip of sizes. The size of p eop le is th e handiest reference for oth er sizes; this is call ed human scale. Alth ough it is obvious that all structures ca n not be wi t hi n our scale, w e ca n feel m ore com­ fortable w ith a large bui ldi ng if certain of its features range in size fr om human scale to the overa ll build­ in g. Throug h grap hic analysis, w e can begin to under­ st and how scal e is ha ndled in different bui ld ings. The effect of prop ortion s on the design of a bui ld­ ing can be represented for analys is in a sim ilar way. Propo rtion is th e relatio ns hip betw een di m ensi on s (horizontal-vert ical). Through abstraction, the impact of p rop ortions on ex ist in g build ings ca n be bett er unde rstood .

Furtherm ore, m ass and balanc e are associa ted w ith m any ot her feelings, such as sec ur ity and flexibili ty. In a bu ild ing, a sense of ma ss can convey sec uri ty or perman ence; a sen se of air iness can convey flexib ility or fr eedom . Th roughout arc hitec tural history, many met hods have been di scovered for varying the appar­ en t m ass of build ings. By anal yzi ng b uild ings th at hav e clear sensations of m ass, the use of su ch formal devices as hor izonta lity, verticality, and em phasis ca n be uncov ered . Walking is a tremendous feat of ba la nce . M uch of the enjoyment of w alking, rid ing a bike , skiing, and th e like is derived fr om the ten sion betw een stability and instability. We have a fin ely tuned sense of bal­ ance that carries over into our visual pe rcep tion.

Repetition/ Rhythm One way of ac hieving unity in a build ing is throu gh re pe tit ion of parts that are alike, suc h as w indow s or column s. Simi larity of objects, even if on ly pa rtially sim ilar, is a w ay of emp h a siz in g associa ti on . Me m be rs of th e h um an race are recogn ized by a numb er of sim ilar featu res in spite of th e gre at d iver­ sity in their ind ividual appearance . The importanc e of rhy th m in architecture is ba se d upon its relationship to the h u man rhyth ms, w a lking or bre athing, and the natur al rhythm s, the tide or the sea so ns. Just as music pres en ts au d io rhyth m s, archi­ tectur e displays visua l rhy thms In ar chitecture, th e pr in cipa l m ean s of ach iev in g r hy th m is spacin g of p ar ts; this is co m p arable to the in tervals bet w ee n beats or notes. The chara cter of visu al rh ythms in a bui lding dep ends on th e size of both the interv als and th e parts. Two basic typ es of rh ythm can be identi­ fied . Staccato rhythm is form ed by clear d istinction between in terva ls and parts , such as mu llions on a curtain wa ll. Legato rh ythm is softer, formed by mo re su btle tra nsition s betw een inter val s and parts, as in th e curvilinea r ar ch itec ture of Gaudi . There ar e also rhyt hms d isting uishab le by p attern s of in te rva l or part sizes, as in a facad e by Pallad ia . And ther e are accelerat ing or decel era tin g rh yt hm s, as in the Wolfsbe rg Ce nter by Aalto.

Unity/Diversity The d egree of unity or d iversi ty exp ressed in a b u ild­ ing con st itutes ano ther class of form variables. The "other varia bles (scale, p ropor tion , m ass, ba lance, rep­ et iti on , or rhy thm ) can be used to ach ieve unity or diversity.

ABSTRACTION AND PROBLEM SOLVING Th e ultim ate use of abstract diagrams is to h elp the design er com m it to m em ory large amoun ts of project in form ation . T hese diagrams can also be used d irec tly as a record of d esign varia bles . T he ma in advan tage of d iagrams as a graphic record is the ir im m ed iatel y accessible inform ation when all the dia­ grams are arranged in a large group . Creative design­ ers fill sheets upon sheets of pa p er with diagrams and sketche s of all types to record what they k now and thin k about a design problem. An ab st rac t diagram m ust be sim ple an d clear to be effe ctive . If it conta ins more in for m ati on than can be absorb ed at a q uick glance, it loses its effective ­ ness. Yet, it m ust p rovi de eno ugh inform ation to form a di stinct idea . Lim iting th e size of the diag ram to a por tion of our vi su al fie ld is a m et hod of par tia lly con troll ing the amoun t of inform ation given . A stan­ dard 8.5-by-ll sheet of pap er fits wi thin the vis ual field of a single ind ividual, and th e drawn d iagrams can be as small as a ha lf-dollar. W hen several design ­ ers work as a group, the vis ual field is expanded con­ siderably. Th e fir m of Ca u dill Row lett Scott has developed th e "ana lys is ca rd " techniq ue for group wo rk . Diagra ms, each about the size of a ha n d, are drawn on 5'/z-by-8'/4 card s (I have perso na lly tried 3­ by-5 and 5-by -8 ca rd s with success) . During the pro b­ lem ana lys is and desi gn process, diagrams are draw n on the cards, w h ich are the n ta cked on the wall for d isplay to t he gr ou p . Th is results in a con ti nua lly updated d isp lay of the gro up 's thinking. As an added benefit, the cards are easily m ove d to prov ide flexi­ bility of ideas by association . For legibility, ink or felt-tip pens are prefera ble to pe ncil or other media . Line w eights should be geared to the viewi ng situation : a fine -line pe n is good for the individual b ut a heavi er mar ker is be tter for group di splay. Som e architec ts make the translat ion from individual to gr oup display by simp le en large­ m en t of th e orig in al diagrams or ske tches.

It is simp le enough to list those "attributes of creativ­ ity " whi ch are needed by the designer and to point out the reaso ns for their inclusion. But actual devel­ opment and refinement of such beha vioral charac ter­ istics is di fficult since society ma ke s it a relentless bat tle, an often thank less an d rarely positively rein­ forced chore, to ma intain such behavior. The same society which readily accepts the crea tive 'produc t' will chastise or deny the creative 'activity ' required for such produ ction because of its non-typical natu re. I

OPEN-ENDED IMAGES Terms like amb iguous, collage, and m ulti va lent have be en used to descr ibe wo rk s of art and archite ct ur e that can be "read," in terpreted , or appreciated simul­ tan eo usly on sev eral lev els. These works a re ofte n sai d to have severa l meani ngs. Design sketches ofte n ha ve sim ilar q ua lit ies of a m big u ity, allow ing the design er to thin k flexibly and in gene ral terms. I refer to thi s as op en -ended . Open -ended ness can be ac hi eved wit h transparen cy. Thi s ap proach is based on the trad ition of show in g dept h location by over­ lapping.

TRANSFORMATIONS The p urpose of ope n -ended images is to invite ch anges in the images. Transfor mations , however, are specific ch an ges made in t he grap h ic im ages . Th e possib ilities for change in graph ic im ages are practi­ cally un lim ited , bu t we w ill look at a few basic types of tran sform ation . They are topologi ca l con tinuity, orname n tal gramma1; revers als, and distortion. Graphic transforma tions ca n be very hel p fu l to creativity in desig n . The stages of crea tiv ity have bee n described by Hele n Rowan as "Prep a ration , In cu ba tio n , Ill u m ina tion , and Veri fica tion .... th e period of in cubation fr ees the ind ivid ual fr om previ­ ous fixations, he is then able to see the problem with new eye s whe n he re turn s to it. " 3 Tra ns formations are aim ed at changing perspective or p erceptions, m ak ­ ing the fa miliar se em strange. It is im po rta n t to remember that a peri od of p re para tion m us t p recede in cuba tion . The de signer prep ares by be comin g im m ersed in th e p roblem , tr yin g to u nd erst a nd a ll the var iables of need , contex t, and for m . O nce the problem becom es imbedded in his m in d , he attempts to overcom e preconceptions about the p oss ible solu­ tions by changi ng the existing grap hic im ages.

Topological Continuity In m at hem atics, the term topology is defined as "th e stu dy of th ose p r ope rtie s of geom etr ic figures th a t

rem ain un changed even wh en under distortion, so lon g as no surfaces are torn ." A practical example of two objects topologica lly similar bu t d iffere nt in ap pe ara nce is the doug hn ut and the cup . The trans­ form ation fr om do ughnu t to cup shows how the same basic surface re lat ionships are re ta ined w hi le t he form is p us he d and pu lled. A similar topologica l co nt in ui ty is impo rtan t to the exploration of design im ages. Many arc hitectural students mistake a specific ar rangeme nt of pa rts for a topological or essential re lationship of parts. If the tr ue topological characteristics of a diagram are iden­ tifie d , many other arra ngements of the parts can be exp lored. March and Stead m an pointed out the poten tial of topol ogical con tin uity in comparing three houses by Fran k Lloyd Wrig ht: I n them he uses a range of "grammars, " by w hich he me ant, abo ve all, the controlling geometric un it which ordered the plan and pervaded the det ai ls... . Wh ilst they may lool: di fferent, they a re in fact topo­ logically eq uivalent. I f each funct ional space is mapped on to a point a nd if, whe n two spaces in ter­ con nect, a line is dra wn bet ween their represen tative points...we find tha t th ey (th e houses) are topologi­ cally equivalent in plan. T herefore, one topol ogical structu re was open to thr ee velY different ex pres­ sions.'

Ornamental Grammar Thomas Bee by, in h is art icle "Th e Gr amm ar of Ornamen t/O rnam ent as Gram ma r," clearly illustrates th e app licatio n of ornamental grammar to building m as sing and design at many sca les by the m aster a rch itec ts of the m odern m ovement. Spe cifically in th e w ork of LeCor busi er, he show s th e impact of th e trad itional tra ining in orna m entation principles. A d irect me ans of achievin g a rich comp lexity in bu ild­ ing forms is revealed. "LeCorbusiers early tr ain ing in orn am en t pla ced a valuable method of working with in his grasp.

[The re are] four basic manipulations of a uni t to cre­ at e orname nt: tra nslation, rota tion, reflection, and inve rsion . The simplest type of band orn amen t, tran slation (illus tration I] , is the repetition of the unit, always in the sam e orientati on, along a hori­ zontal axi s. Rotation (illust ra tion 2) is the repetition of the un it around the point of in tersec tion of two adj acent sides. It accounts for pin wheels and othe r spiral configurations. With tran slation an d rotation,

the unit merely slides along the surface of the pla ne, in a straight line or a circle, but in both reflect ion an d inve rsion the unit is flipped over in spac e to presen t its under side. W ith refle ction (illustra tio n 3), the unit is flipp ed over on one of its edges, producing bilateral, or m irror, symmetry. W ith inve rsion (illus­ trat ion 4), the un it is flipp ed over its centra l horizon­ tal axis . More complex configuratio ns are derived from a combination of these fou r basic operations. Translation accompanied by reflection is probably the most famili ar. Transla tion acc ompanied by reflec­ tive invers ion is another typ ical opera tion (illustra­ tion 5). Th e complexity increases through devices suc h as shifts along the horizontal axis, or glid e line, leav ing gaps between uni ts, to produce slipped reflec­ tion or alterna tion (illustra tion 6}.. . . A lso, by accel­ erating (illus tration 7) or decele rating (illustratio n 8), the rhythm through decrea sing or increasing eith er the size of the units or the distance between them, one can tra nsform sca le,'

Reversals Reve rsals are cha nges in an ima ge fr om its fir st char­ act eristics to op posite cha ract eristics [ligh t to dark , object to space, open to closed , etc.). Th eir us efuln ess derives fr om th e qualities of the contra sting comple­ m ent. Th e Chi nese philosophe r Lao-Tzu held tha t th e essen ce of everything we could see lies in what we can not see; the esse nce of m an is not in his physical appearance, and th e ess enc e of arch itecture is not in the visible str ucture. The Taoist sym bol yin and ya ng re p rese nts th e absenc e of ord er, chaos, as a bl ack backgrou nd ; the tw o r evo lv ing for ms are yin and yang, th e con trast in g com plemen ts th at m a ke up or d er, n igh t a nd day, a m u si cal n ot e and a pau se, active and passive. Th e ide al condition , pe rfec tion , is symbolized as a dynami c balance between op posites: gro ups of people are defined by ind ivid uals and indi­ vid uals are defined by groups; th e color of an orange change s in intensity w ith the changing background .

Archit ectur al examples of complemen ts are w alls and openings , m aterials and the joirits betw een ma te­ rials, vertica l and horizon tal , rectilin ear and curv ilin­ ea r. To ch a nge our p ercep tions, w e ch a nge th e em phasis of an im age to its com plem en t or contrast. The simp les t for m of rever sal is called figur e-ground drawing. Two sketches are m ade of a sub ject su ch as the Piazza San Marc o (oppo site ). In one sketch, th e build ings are shown in solid black an d in the oth er ske tch , th e space between the bu ildings is sho w n in bl ack . By look ing at the tw o s ketc he s at the same time, it is po ssible to get a better under stand in g of bo th space an d bu ildi ngs a n d the re lationsh ip between th em .

He ach iev ed di st ort ions th at dramat ica lly alter our view of re ality through simple man ip ulat ion of these rep­ resent ationa l systems, as in th e lit hograph Ba lcon y. By w ay of an exaggeration of the projection m ethod used for maps of the w orld , he imposes a simple grid over th e co nventional drawin g and th en doubles the size of the cen tral sec tion; th us the di storted gri d is used as a referen ce sys te m to comp lete the dr aw ing . The gr id-man ipu la tion m ethod can be used as a simp le way of di storting oth er typ es of im ages. For our p urpose , the gr ids should be kept quite simple to rem ain in a sketc h sty le.

Matrix

T h e matrix provides still another way of applying order to the transformat ion of images. The example at right illustrates the basic application of a matrix. Differen t concep ts of building placement on the site are show n across the top, a nd differen t degrees of ar ticu lation are indicated in th e vertical d irection . By sh ow ing the combinations of th e two considerations, a number of forms evolve. T he example below (from a stud ent project) is a search for alternative configu­ ra tio n s of an urb a n zo n e development. The basic order s are shown in th e left vertical column and dif­ fe rent combi na tion s of city bloc ks in the r igh t col­ umn . Fr om these, different in terpretations are formed .

It ca n be a n energizing exp erien ce th at be comes addictive . Relax and enjoy it! Part of the p ote n tial of exploration derives from th e fact that ide as breed id eas. As the graphic think­ ing cycl e gets m oving with ease, the gr oup of ide as ra pid ly expands in a very rough py rami dal p rogres­ sio n. If only tw o new images are perceived for ea ch one draw n, th e gr owth in id eas can be am azing , but for many designer s this is a big "if."

THE DISCOVERY PROCESS For the ar chit ect or th e designer, the process of d is­ covery consists of tw o parts: inv en tion an d concept for­ mation. Invent ion seeks the basic discovery, th e origi­ nal idea for th e project ; concep t form at ion co nverts the discovery int o a graphic and ve rbal sta teme n t that can give ba sic direction to the full development of the project.

Invention David Pye w rote tha t invention "can only be done deliberatel y, if the inven tor can di scern simi larities be tween the par ticu lar result which he is en visaging an d some other actual result wh ich he has seen and stored in his m emory.... An in ven tor 's power to in vent de pends on his abi lity to see ana lo gie s between resu lts and, secondarily, on h is abi lity to see th em betwe en devices. " 3 The ana logies ar e easily rec­ \ognized in our everyday inv ent ions. If we lack a ham­ 'fIler to drive te nt stakes in to the ground , we gain an Insight to th e solution by seeing a tent pole se ction or \ a ro ck at arm 's length an alogous to a hammer. Burrs caught in she ep wo ol were the inspiration for Velcro fasten ers, and the cooling effect of th e evap oration of perspiration from our skin is the basis of the idea of using semiporous containers to keep water cool.

Again , using th e exam ple of the re crea tio na l ho use, we can sketch out a ba sic approach to inven­ tion in architect ur e. Th e starting poin t is the abstrac t diagram of the program for the house. This leads to a choice of one im age of a hou se, nam ely a conta iner th a t ho lds peop le. Alm os t si m u lta neou s with t he house image w e have a n ana logo u s im age , th e pi tche r, as a container of liqu ids. In th e fourth sket ch , the ideagra m , the house program , and the image of the pitcher ar e com bined to form a specific d iscovery of how the re cr ea tional house m ight take sh ap e. In this exa mple, the ho use is also see n as a conta iner of energy, adm itting so lar en er gy th rough a hole in the top simi lar to the hole in the top of the pitcher. The concep t for the house co uld be form ed fr om thi s idea­ gram or the a na logy could be extended f urt he r throug h observations suc h as : the on ly entry in to the pit ch er is thr ough the top, so perhap s the m ajor ent ry into the ho use could be via a stair drop ping in to th e cent ra l court.

The fourth type , fantasy a nalogy, uses a descrip­ tion of an ideal condition desired as a source fo r ideas. In the case of our recreational hous e, the designer might fantasi ze about a house that op ens itself up when the client arrives on the weekend and automatically closes up when the cli e nt leaves. It could be compared to a tul ip that opens an d closes with the action of sunlight, an automatic garage door, or a puppet that com es aliv e wh en you pick up the strings. The de cks and the roofs over the de ck s could be like the leaves of the tulip . But how do they op en and close? A motor is a noth er en ergy cons um er ; is there another way? How can the puppet strings help? The fin al solution uses ropes and pulleys to raise an d lower the flaps. The sy stem is balanced so that the weight of a person on the de cks can pull up the roofs , and the dropping of the roofs cou ld pull th e de cks back up . The de ck s and roofs would be held in both open and clo sed positions by spring lat ches.

Eo lith ic Design Some times designe rs suc cumb to what Rober t McK im ca lls "func tional fixedness," the "te ndenc y to sort objects into in de libly labeled con ­ tai ner s."" As a resu lt , th ey a re unab le to see their pr ob lem in any other ligh t; kit ch ens or bed room s, for example, are seen as having a single use. One cu re for th is di fficulty is eolithic, or found-object d esign ; the norma l use of an object is d isregar d ed in fav or of a new use. Examples incl ude barr els of water used for heat stora ge, trees used as scul pt ur e insid e a house, do ors used as cou n ters. The co un te r a nd storage set up of the ki tch en could be used as a mo de l for a stud io or othe r workspace, an d the bed room mi ght be converted int o a d ining or loungin g space. The fou nd ­ obj ect ap proach can also be used w ith id eagram s; the b inoda l or gan iza tio n of a typi ca l sh op p ing cen ter mi gh t be used in a hou se to genera te more m ovem en t and in teraction . Escape Sometimes j ust getting away from the probl em is enoug h to loosen the m ind and open fresh view s of t he projec t. Escape can ta ke the form of d iver sion s suc h as en ter tai n men t, sp or ts, or games ; it can also be simply rest ' and relaxation , or "sleeping" on the problem . Random Thoughts Even when not actua lly wo rk ­ ing on a problem, our subconscious minds are often still try ing to solve the problem . Then sudden ly we get an idea or an answer to the design pr ob lem. Some design ers have these insights just as th ey are going to sleep or upon wak ing. It is im port a n t to wr ite or sketch the se id eas before th ey are lost. For this rea ­ son , many architects carry small notebooks with th em or keep paper and pe n han dy near their bed s or othe r places of relaxation . Sense Awareness Work ing in a predo m inan tly vi su a l m ed iu m ca n sometim es lead to igno ring t he othe r senses and may cu t a designer off from a large n u m ber of sources for analogies. If we thi nk o f a house as bei ng soft as a p illow in a box, it m igh t lead to the use of curvi linear par ti tio ns . Comparing a hou se to a m us ica l in strument co uld resu lt in a me ta l roof to catch the sound of th e ra in or some w ay to am p lify th e so u nd of a breeze.

If th is d iscuss ion of th e use of ana logie s seems too simplistic, rem em ber the gr eat architects of this cen ­ tury. Wrig h t, LeCorb u sier, a nd Aa lt o used simp le a nal ogies as a sou rce for many of their in ven tion s: Geoffrey Broa dben t co m m en ts : M ost architect s-a nd ar tists- are ex tremely reluctan t to adm it th e sources of their analogies. They think that su ch adm issions would some how dim inish one 's respect for their crea tivity; bu t far from it-they will merely confirm that they ha ve brains and me n tal processes, which every oth er huma n being possesses . O ur respect {or them , in fact , m ight increase if they adm itted tha t, given the same me ntal processes, they are ab le to mak e bett er use o] them. " 5

Broa dbent goes on to des cribe a n um be r of analo­ gies that LeCorbusier used in h is work, an d ob serves that he spe n t .. ,a lifetim e bu ilding up a store of analogies (his years of sk etching being pa rticularly fru itful). T he ana logies had become fundame nta l to his experience, a bsorbed, compared, contrasted, com bine d, overlaid by la ter exper ience, and cha nged by new percep tions; but they were th ere to be called on, an d faced with a difficu lt design problem, LeC orbusier could draw on them . We too have our stores of an alogies, no t per­ haps as rich as Letlorb usier's, but valuable neve rthe­ less, because they are personal. Yet we fail to draw on them . It never occurs to us; they do not seem rele­ van t and ins tead of tha t, we content ours elves by draw ing analogies with ot her people 's work . "6

Concept Formation Th e basic concept, some t im~s referred to as the patti, is an enduri ng mechanism used by architectural design ers to es tablish th e fundamenta l organization of a building and guide the enti re p rocess of design d ev elopment. T h e parti, at its best, p rovid es: 1. T h e first synthesis of the designer 's re sponse to th e determinant s of for m (p rogram, obj ectives, context, site, economy, e tc.).

2 . A bounda ry arou nd the set of decisions tha t will be the focus of th e d esign er 's responsibility. 3. A m ap for fut ure de sign activities in the form of a h ierar chy of valu es and responding forms. 4 . An image tha t arouses expectations and provides mo tivat ion for all persons in volve d in the design p r oces s. This is often done through the use of a bs tr act ions. ("My buildi n g is a sp in e " or "O ur building bridges this gap .") The typica l parti sketch, lik e the one on th e left by a fifth-year th esis st udent , shows both the d et er m i­ na n ts and t h e b asic resolution of the form . In this exa m p le , the sk e tc h of a floa ting resea rch sta tion in the Atl a n tic O ce a n ill us tra tes the ve rtical pontoons secured by ca bles, supp orting a mu lt ilevel pl atform. T h e b asic in te rac tion w ith w a ter, wind , and s un is also ind ica ted .

The Ideagram T h e sket ches t ha t have alread y b ee n described as flowing from an alogies, kn own as ideogram s, ar e the starting p oin t for concept forma tion. Ideagrams are extensions of an alysis d iagrams that can be used as:

1. An aid to investigat ion a nd sy nt hesis in the d es ign process. 2 . A fra m ew or k in the de sign thin kin g process that lead s to the fin al de sign product. 3. A lite ral m odel of the fina l p roduc t. In architec­ tur e th is is referred to as conce p tual clarity in th e build in g. 4 . An exp la nation of a design con cept after the build­ ing d esign has been completed . To show some of the p oten tials of the id eagram for d ev elop in g design concepts, I hav e drawn three st ages of ev olu tion of a n ideagra m in th e fir st column to the right. For ea ch stage, th ere is a sch ematic de sign for a b u ild in g in th e n ex t column. Shown in Ideagram 1 an d Design 1 is a literal tr an slation of the ideagra m in to a bu ilding for m . T h is approach has a clear and fo rcefu l impact on the us er ; the effect is sim p le an d dramati c. In Ideagra m 3 and Des ign 3, a build in g form is be in g de rive d from a mo re complex ideagra m . The resulting b u ild in g m ay la ck the sim­ p licity or in itial im pact of the first build in g , but in tu rn it may offer a greater va riet y of exp er iences.

Pattern Language For several years, a group at th e University of Califo rn ia/Berkeley, headed by Christopher Alexander, has been wo rking w ith a m et hod of generating build­ ing des igns, called patte rn lan guage. Basically, it is an approach that const r ucts con cep ts for a building by com bining pr ototypes for sm aller pa rts of th e bu ilding. The work ing tool is a hierarchy of prototypes: areas th at com bine to make roo ms, that combine to make build ing s, that com bine. to m a ke co mm u ni ties, th at combine to mak e urban complexes, an d so on. Pattern language appears to be less a prescription for the per­ fectly designed environment th an a convenient format for form ulating design conc epts. Any designer is free to supply his own prototyp es, alth ough there is cer­ tainly m erit in sharing wo rkab le prototypes. Application of the pattern lan gu age approach, on th e simp lest leve l, to our ho use proje ct mi ght take the follow ing form : 1. Based on past experience, we wou ld start w ith an

array of p rototyp es for di ffe re n t spaces fr om w h ic h w ould be se le cte d th ose th a t seem m ost app ro pria te for th is proj ect . The prototype d ia­ grams are q uite sim p le, with short verbal identifi­ cations fo r ea se of ident ification an d m an ipula ­ tion . 2. The diagr am s ar e combin ed into a p att ern that re prese n ts a sum m a ry of th e building ele me nts and show s an over all idea of th e building.

At a m ore sop histica ted level of app lication, ~: 3 ill us t ra ted on th e fac ing p age , sp ace p roto ty pes or pa tt erns are more speci fic and ori ented toward three­ dim ens ion al experience. Th e chara cter of th e space be comes a foc al po in t for the ide n tity of the pr oto­ typ e. Represe ntation al skills, di scu ssed in Chapter 3, ar e obviously a he lp here. I ha ve fo un d tw o useful ways of coll ectin g pa t­ terns an d us ing th em in design : Th e B uilding Type N otebook- An idea for a sp ace is illu stra ted on an S'/z-by- l l she et of pape r. Th ese sheets are kept in a thr ee-rin g binder and us ed as a referen ce book for future projects. A nalysis Ca rds- Patt ern s ar e recor ded on sm all ca rds sim ilar to the on es described in Chapter 4 . Thes e can be filed by su bject , re ady to be pulled ou t for a sp ec ific design task.

Wh ether using cards or standard-size sheets, it is hel pful to have a com m on format. Th e basic informa­ tion include s a simple statem en t of the programmati c n eed and context ("dining sp ac e in a tow nho use ap artm ent "); a concise verba l an d graphic stateme nt of a p rot o typ ical resp on se to t he ne ed ; a mo re det ailed de scription of the prototype or di scussion of the pa ttern th at is re corde d on th e back of th e ca rd or sheet.

Whe n the desig ner is formu lat ing concepts for the bu ildi ng design , he sp reads the collec tion of releva nt cards or sh eet s on a table or wa ll. Patterns or mini ­ concep ts are then grouped as possible combina tions an d observed, but the designer m ust go beyond a sim­ pl y add itive pr ocess, In describing "pa ttern lan ­ guag e, " Ch ris top her Alexa nder exp lain ed that "It is possi ble to put pattern s togeth er in such a w ay that man y, many pa tte rn s ov erlap in the sam e physical space : the buildi ng is ve ry dense ; it has many me an­ ings captured in a small space; an d through this den ­ sity, it becomes pr ofo und .

Verifica tion can be describ ed as a cycl ical process p rodu cing im ages th at are in creasin gly spec ific or con cr et e.

EVALUATION

re cogni zed by the w eighti ng of the cr iteria . Differe nces in va lue s still have to be ne gotiated , but th e de sign er can at least illu stra te the relationshi p betw een va lu es a nd the eva luation of a specific de sign .

The definition of evaluation , p lacing a value on som e­ th ing, im plie s that th e re exists a set of va lu es to w hi ch the eva lu a tor refe rs. W h en evaluat ing a de sign , we use design cr iteria to represe nt these val­ ue s. Th e first con cern of des ign cr iteria s hould be comp re hensive, cove ring a ll as p ects of th e design pro blem . For conven ienc e, I have us ed as a m odel the hou se design problem described earlier. Criteria are de lib erat ely developed under ea ch of the three ca te­ gorie s of need, co ntext , and form , and a chart, su ch as the one in Figure 9-6, is co nstruct ed to assure that we look at the de sign co nc ep t from every angle. The second conc ern of design criteria is how and w hose values th ey re presen t. W he n desig ning a build ing, de cisions are usuall y made on the basis of comp e ting sets of va lue s h eld by the client, th e desi gn er , the in tended user, and even society (in the form of custom s or reg u lations). In addition to sh ow­ in g a n arr ay of cr iteria, a balan ce of va lu es ca n be

The third concern of design criteria re lat es to the d ifferences in the way w e look at des ign ideas. Som e ar chitec ts ca n be said to be m ore con ceptua lly or i­ ented ; that is, the ir evaluati on is heavi ly influen ced by su ch thi ngs as organization , consistency, and hier­ ar chy as they ar e reflected in plans and axonomet rics. Percep tually oriented ar chitects are m ore in terested in the d ire ct exp er ience of a person ou tside or in side the buil d ing. In m y opinion , both concepti on and per­ ception are imp ortant to the exp erien ce of a building and, th erefor e, im porta nt to the eva luation of design co ncepts. Th e de signer m ust be aw are of these two orien tat ions of de sign and try to ta ke a ba la nced ap proac h to eva luat ion .

A DESIGN PROCESS Regardless of wh at is being d esi gn ed or w ho is involved in d esign ing it, th ere is a co m m on objective: translat ing the clien t's p rog ram in to a spec ific bu ild ­ ing or ano ther resp onse to his needs.

I try to show how som e of the grap hic th inking too ls h ave bee n help ful to architects and desi gn ers, but the real te st of the usefu lness of th ese tools has to be m ade w ithin the context of the sp ec ial des ign pro cesses ea ch of us develops.

Although th e draw ings that sum up each stage in the de sign pr ocess vary from abst ra ct sk etches a t th e begin ni ng to the most spec ific hard -line drawings at the end, th e thi n king process can be supported throug hout by the d iffer ent types of ske tches pre­ sen ted in the p revi ous chapters.

PREPARATION FOR DESIGNING Although thoughts can be represented graphically by using a great number of me d ia (and there are whole books devot ed to these di ffere n t m ed ia ), eac h designer must find m a terials and instr umen ts wi th which he w ill be most com fortable. It is w orthwhi le to experim en t w ith the se di fferent tools. They should be eas y to use and m ai n ta in, and th ey shou ld be portable . Per sonally, I prefer pens to p encils because the y produce a high-con tra st im age, mak ing consis­ ten t lin e qu ality easy. T hey are p erma n en t , whi ch d iscourages th e tim e-consuming habits of erasing or redraw ing. I ha ve found four types of pen that meet my needs: Liquid-ink ca rtridge pen-Using perm an ent, jet blac k

ink; it prod uces a sm oot h, q uick line. Most po ints w ear ou t even tually, so I use cheap p ens w ith fine rounded points and ke ep sever al handy in case one w ears out. Pointed felt -tip pen-T h is us ed to be the m ost com m on type of felt- tip . It has the ad vantage of provid ing a second line w eigh t by using the side of the point, but th e ink oft en th in s out, resulting in less shar p images. Fin e-point felt-tip pen-Many of these p ens have a th in m etal tube that greatly reduces the wear and

defor m ing of the point. Look for the pens wi th the darkest bla ck in k. Extra-fine-po int rollerball- These us ed to p roduce an un ev en or unreliable line , but have been great ly improved and have a longer-last ing supp ly of ink. For good res ults, the d rawing instr um ent m ust be mat ched wi th the ri gh t p ap er. Alt ho ugh th e liq uid cartrid ge pen works on mos t pap ers, no np orou s, sm ooth-fi n ish pape r is th e m ost adap ta ble fo r all pen s. I buy cheap , wh ite 8 1h -by-ll ph otocopy pape r in SOO-sh eet pac kages. My test for a n a cce p ta b le m a tch of pen and paper is w hether th e pe n can be m ove d qui ckly in an y d irection without ca tchin g or sk ipp ing. Many architects get good resu lts wi th soft pe nci ls or colored p en cil s, a nd so m e co m bine m ed ia . Everyone's in terest s and thin king di ffer, so eac h per­ son shou ld tr y to find a sim p le bu t eff ec tive m ed iu m for th eir personal gr aphic think ing .

ENVIRONM ENT It is cur ious th at ar ch itects, whose p rofession is con­ cern ed with suiting environments to needs, spend lit­ tle tim e stud y ing the environm ent in w h ich they

Figure 11-6 Studio environment set up.

w or k. Robert McKim provi des us wit h a good descr iption : A visual-thinking environment for one person should be as well-designed as a contempora ry hi tchen. Work areas should be well illum inated, preferably w ith natural north light and with out shadow or glare. The drawi ng surface sho uld be large and adj ustable in height and angle. A n additional stand­ up table should be ava ilab le for three-dim ensional work; spilled glue and knife ma rks soon spoil a drawi ng surfa ce. Organized storage should be pro­ vided close to each work area to diminish distracting clutter. Chairs an d stools should provide back sup ­ port in a wo rk ing position. To alleviate back tension and also to provide for the importa nt element of change, a stand-up, verti ca l draw ing su rface should be available: a black board, ease l, or wall- m ounted roll of paper. A large tack- space is needed for dis­ playing current idea ske tches . A lthough admittedly an affront to those who associate productive work with open eyes and erect position, the visua l thinker should also ha ve access to a qui et place wh ere he can relax and tum his thoughts inw ard- or stop think ing entirely: a reclining chair, a couch- even a relaxing bathl'

p lem ent th eir ow n s ty le of thin kin g. I find th at my ow n de velopm ent m ak es m e res ponsive to eve rything visible. I support concentra tion by using a clea r desk wi th a blank w hite vertical sur face direc tly in front of m e. O the r de signers may need a very s tim u la ting envi ronm ent for thi n king.

MENTAL/PHYSICAL CONDITION Th e right materials and environme nt m ust be accom­ panied by a good m ental and p hysical state for th e indi v id ua l to th ink or solve problem s effecti ve ly. Eve ryone is su bje ct to tension and stress in th eir work, and this is esp ecially tru e of p racticing arch i­ tects. Experienced architects try to pace th emselves because th ey know that m istakes are m ade under excessiv e pressu re. Freq ue nt exe rcise and re creation are a bas is for a good m ental state , bu t designers can also take specific m ea sures to improve th eir prepara­ tion fo r w or k . Relax eyes by closing, the n ro ta ting the m ; ease neck tension by sitting up right w ith bac k suppo rted and slow ly bend t he head forw ard , ba ck­ wa rd, and to ea ch side in a cir cular mo tion; relax the w hole bod y by stretching and deep breath in g.

G rap hic thi n king is m ost effecti ve w hen it respec ts ba sic thinking processes.

Within the range of these sketches, th er e ar e tw o ba si c tenden cies : exp loratory abs tract sketc hes an d defin itive conc re te ske tches. Accor d ing to M cKim , th ese respond to tw o typ es of thin king. "The first is fast , cru de, holistic, and par allel, while the second is d eliberate, a tte n tive , detailed and seq ue n tial. ", Designers gene rally lean toward one or the other of thes e types of think in g and pro bably use a lit tle of both . To in cre ase effectiveness, each designer should be aw are of his basic typ e of th inking an d be abl e to re cogn ize wh en the other type is appropriate.

CONCEPTUAL TO PERCEPTUAL THINKING

Figure 11-7c Hardline drawing.

Concep tu al thin kin g se eks out the un derlyi ng struc­ ture, order, or m eaning of experience; it attempts tak­ in g possession of the exper ienc e, comp aring it w ith other experiences, and interpreting it in the light of our kn owl edge of reality. Perceptua l thinking tries to take in the d irec t experience of an environm ent, not­ ing th e ele m en ts from w hich it is composed and the personal reactions th e environm ent evokes . Often these two modes of thinking are thought of as sepa­ rate or eve n in opposition . Cre a tive, dynam ic thi nk­ ing depends upon full integra tion of conception and per ception because they inform and give m eaning to each other. Know ing that there are about four hun ­ dred variet ies of goa t' s-m ilk che eses produce d in Fran ce adds somethin g to th e ex pe rien ce of eati ng one of th em ; neverthel ess , knowledge of these vari­ et ies does n ot ha ve much me ani ng until you have tasted on e of th em . The history of Gothic church con­ stru cti on , incl udi ng prin cipl es and vari ations, w hen com bined with th e overwhelm ing sensations of mo v­ ing through the darkness an d light of a Go th ic church nav e, provides a complete, integrated aw areness that could no t be achieved should either th e conceptua l or perceptual el em ent be missing.

The de sign er must be able to move fre ely between concep tual an d perceptual thinking and shou ld avail himself of a variety of grap hic me ans to achieve th eir int egration .

OVERCOMING OBSTACLES Eve n the best preparation does not assur e success in d esi gn . Arch itec ture st ude nts and some tim es even practit ione rs ru n in to think ing an d p roblem-solving obs tac les . The fo llowin g lis t describes some of the m ore com m on obsta cles an d so me possib le responses.

1. Can't get started-If you try to tackle proble ms tha t ar e too big, you be com e ove rwh elm ed . Try to br eak dow n the prob lem into d ifferen t parts. In st ead of design ing the w hole school, analy ze its pa rts: class­ rooms, r ecr ea tion , ad m in istra tion , etc . W hen th ese pro ble ms are under control, look at how th e pa rt s can fit toget her to form a school.

2. Can't get any good ideas-Sometimes we have a fear of fai lur e; w e are afraid th at our solution will be judged to be very p oor py others and that th ey w ill lose confide nce in us. Thi s req uires separ ating one 's se lf from the design problem . If failures in life mea nt that one's life was a fail ure, we wo uld all be in de ep trou ble. Fortuna tely, life goes on, and thi s problem w ill soon be forgotten . T he fu ture hold s d ifficult problems as we ll as ea sier ones. It may help to tr eat the probl em as a cha llenge in a game. Try your best and use a ll of the reso ur ces ava ila ble. Use some of the techn iq u es of ma n ipu la ti on already disc ussed and take a new look at the p ro ble m . If you ca nn ot m ove ahead on the basis of your ass umptions, then arb itrarily cha nge the m . If there doesn 't seem to be a su itab le so lu tion for the kitch en, consid e r a ho use w ithout a formal ki tch en . It may not be a solu tion , but it m ight lead to a solution .

DESIGN AS A LIFETIME PROCESS Des ign me thodo logy has some di fficult ies, such as its focus on the single p roject and p resen ting a rather m ech ani cal m odel of design w or k . It gives th e im pression that the inform ation is poured in at the beginning and at stra tegic p oin ts along th e w ay ; then the machine , call ed logical tho ught, grinds an d ch ew s the inform atio n , expe lling an ap propr iate product at the end . The ac tual co mplexity of the design process mi ght be better u nd ers tood if we ima gin e the machine as hav ing several sw itche s to m ake the ind i­ v id ua l par ts stop a nd go , sp eed u p , or slow do w n. Fur therm ore , each sw itch has a control that flips th e sw itch ba ck an d forth at ra nd om . Th ese controls rep­ resen t the action of the h um an m ind w ithin a design p rocess, fo r o ur m in ds are co ns tan tly active and reacting to a w hole environ m ent surroundin g a spe ­ cific projec t. In many cases, the design pro cess of a su ccessful arc hi te ct becom es unde rstandable w hen seen as one sma ll part of the ar ch itect 's life. His de sign p ro cess is gov ern ed by p att e rn s of tho ught , in terests, and values that are con stantly evolving. G ra phic thinking can be a significant aid to such de velop m ent.

Je n cks goes on to qu ote LeCorbu sier: "W hen one travel s a nd wor ks w it h visu al th ings­ architecture, pa inting, sculpture- one use s one' s eyes and dr aws , so as to fix de ep down in one 's experience what is see n .

W ith very few exce p tions, the arch i­ tec t in evita bly wo r ks as a m em ber of a gro up; howe ver stron g h is per sonal ity, he still need s a gr eat ma ny other peopl e-a rch itec ts, techni cians, co nsult­ an ts , co n tract o rs, a nd so on - to tra ns la te his id eas in to reali ty."

A fir m has a be tter chance of sur vival w hen it is based upo n a pr inciple of or ganiza tion rat her tha n the persona lity of a single arc hite ct. The team co nc ep t has expa nde d w ell beyond th e limi ts of the tr ad itional ar chit ectural d es ign team . Teams no w incl ud e clien ts, use rs o f th e intended b uild ing, co n tractors , fin ancie rs, socia l sci e n tist s, man ufactur ers , and sp ecialists. We have learn ed that the su ccess of a design often de pend s on all of th eir inp u ts. Tea mw or k has als o overcom e the constrain ts of time and space. Through th e use of the In tern et, tea m s ma y be compose d of arch itects, cons ulta n ts, a nd cli en ts d isp ers ed aroun d th e globe in di ffer ent time zon es .

TEAM DESIGN PROCESS-M AKING A NETWORK W hen many p eople must work toge ther, it is often helpful to make a flowc hart of all th e task s and where the y fit in the context of the enti re project. These net­ works evol ved from sim ple ba r cha rts , which s how a sim ple sched ule of ta sks. By sh ow in g th e necessary seq uenc e of tas ks , the basi s is laid for an elementary netw ork .

Networks ca n become qui te el a bor ate if th ey include the m ost minute tasks, but I prefer to keep them sim p le in or d er to concen trat e on the most basic activitie s. This sim ple netw ork bec om es a sort of rack on wh ich to hang descriptio ns of inf ormation need ed for d ifferent task s. Since complex bu ildings or complex desi gn p roce sses requ ire ch anges in tea m composition at di fferent project stage s, a ne twork is also a h andy w ay to ident ify points at which sp ecial exp ertise is needed .

This chap ter dis cusses th e fun dam ental shifts in the pu b­ lic 's a ttitud e and shows how th es e shifts su p port design an d p ro blem-so lv ing processes.

In our century, exp lore rs of th e un iverse ad d ed anoth e r dimen si on w ith th e con cep t of the eart h as a "space ship," a w on­ drously b rillia nt island floati ng in the va st black ness of space. O nce again , th e imp act of our conce p t of re lations hip to our en vironmen t, th e ear th , has a nd wi ll have fu nd am ental conseq uenc es. Ot her dramatic cha nge s have altere d our view of the wo rl d : ho rse and buggy to spaceships; musket to atom ic an ni hila­

Books su ch as T he A ge of D isco ntinuity, Futur e Shock, and The Tempo rary Society' have at temp ted to de scribe these shifts in values. In the ar ea of archite c­ tur e and env iron me nta l de sign , the shift in values is mo st d ramatically expressed in the histori c p reserva­ tion mo vemen t. Now th at change has becom e a ce n­ tral featur e in our lives, peop le are begin nin g to exer­ cise th eir judgm ent over which changes are d esira ble and wh ich are no t. They are developing new percep ­ tions a bout histo rica l bui ld ings as so u rces of con tin u­ ity in comm u nitie s. They seem to seek sta bility in an atm osp here of over whe lm ing cha nge. I bel ieve that w e are see king a new sense of iden ­ tity for ourse lves and our co m m u n ities .

COMMUNITY DESIGN Jim Burns cla imed that archi tects must w ork more di rec tly w ith the p ubli c to avo id the mista kes of th e past. "Some of the envi ronmenta l changes... have had neg­ ative imp acts that were not easily discern ible at first. They seemed to be good things to do-to relocate a museu m or provide new housing or put a spo rts are na in a pa rk . What happen ed eventually was that the m useum lost part icipants, the housing was dis ­ lik ed, the park patrons shu nned the spo rts facilities. Th e reason for these kin ds of failures is usually that the change s broke con nections between people and the opp ortunities their com munity offered. "3

Th e best way to ass ur e th a t p eo p le ar e not cu t off fro m commu nit y opportunities is to involv e them in th e design of th eir communities .

If th e arc hitec ts are to prom ote the involvemen t of the publ ic in the de si gn p rocess, th ey must ta ke a look at th e way ideas are comm un icat ed . Some archi­ tects ar e acc us tom ed to m aking h igh ly polished p re­ se n ta tio ns to cl ie n ts or boards of d irect ors.

Seve ral arch ite cts and plan ners have worked vigor­ ously to develop gr ap hic comm uni cation m e tho ds, making it possible for the pu blic to understand and enter in to the design process. O ne of the innov ators in th is tr end w as Law rence H alpri n: I am concentrating on the issue of people's int erac­ tions with their environment both as individua ls an d in grou pe.: both aspects are important. We hav e been searching for archetypal relationships... in wor kshops which tak e place primarily out in the field T hese taki ng par t work sh ops allow people the opp ortunity to disco ver and articulate their own needs and desires for themselves and for their com ­ m unities... .

14 Conclusion

rch itectu re and the ot he r art s h old a vital p lace in the future of our cult ur e, cr eativity be ing one of th e m ost im porta nt fact ors. Looking ove r th is boo k, it occurs to m e th at mo st of w hat I have written dea ls w ith how or what could be don e an d not so m uch w ith why.

A

T he im p or tan ce of th e a r ts to n ational survi val was p ointed out clearly in th e 195 1 Massey Report comm issioned by the Canad ian governm en t: W hen M r. Churchill in 1940 called the British peo­ ple to their sup reme effort, he invoked the traditions of his coun try, and based his appeal on the comm on backg round from whi ch had grov-m the character and the way of life of his fellow coun trymen. In the spiritual heritage of Great Br itain was found the qu icken ing force to meet the menacing facts of that perilous hour. No thing could ha ve been more "practi­ cal" than tha t appeal to thought and emo tion.. .. Can ada became a na tional entity becaus e of certain habits of mind and convictions wh ich its people shared and wou ld not surrender. O ur country was sustained th rough difficult times by the powe r of this spir itua l legacy. It will flourish in the future in pro­ portion as we believe in ou rselves. It is the intangi­ bles wh ich give a nat ion no t only its essential charac­ ter but its vitality as well. What may seem unimpor tan t or even irrelevant un der the pressu re of daily life may well be the thi ng that endures, which may give a comm unity its power to survive. B ut tra­ dition is always in the making and from this fact we draw a second assum ption: the inn umerable institu­ tions, m oveme nts, and individuals interested in the arts, letters and scien ces throughou t our country are now form ing the na tional tradition of the futur e. l

Architects are pro blem solvers , but the p ro blems of architectur e, like th e problems of our society, run muc h d eeper tha n the so -called p rac tica l level. A building shou ld reinforce the spirit as we ll as provide sa fety and security. Architecture m ust still be an art as w ell as a scie nce.

Visual com m unicat ion is in the midst of sw eeping changes in both m ethodology and scope. Comp uter and vi deo technologies are obvio usly p rovi d ing the designer w ith new graphic tools of a mazing power and speed : computer-aided dr aw ing systems that cut prod uction tim e to a third of conven tional draft ing; expert or semi-expert system s th at bring to bear the power fu l me m ory of the com puter; vide o sim ulation of th e experience of m oving th rough an environment pro po sed by th e designer. Th ese sam e technologies are revolut ionizing th e role of visual com m unication in the public dom ain ; graph ic techniq ues once held as s kills of th e spec ia list are beco mi ng availa ble to anyone with a com p uter ; early exp osure to com puter graph ics and tel ev ision w ill prov ide fu ture gene ra­ tions w ith unp recede nte d vis ual liter acy. In these earl y sta ges of ad opti ng n ew tech nolo­ gie s, it is co m m on to foc us on how we can accom ­ p lish va rious tas ks w ith these machi nes. We becom e fasc inated with de velop ing har dw are an d software that can do more and do it faster. As I suggest ed at the ope nin g of this con cl usion , in or der to gain for o urselve s th e full be nefits of science, w e m u st be eq ua lly focused on w hy we ar e using th ese technolo­ gies. A deeper u nd ers tand ing of the purposes of de sign is the key to de veloping n ew capabiliti es th at are truly supp ortive of our asp ira tions. As Lew is M um for d w ro te: N o matter how completely techn ics relies upon the objective procedures of the sciences, it does not form an independent system like the universe: it exists as an eleme nt in human culture and it prom ises well or ill as the social gro ups tha t exploit it promise well or ill. The machine itself makes no demands and holds ou t no prom ises: it is the human spirit that makes dema nds and k eeps pro mises.2
