No single definition of design, or branchesof professionalizedpracticesuchas industrialor graphicdesign,adequatelycoversthe diversityof ideasandmethodsgatheredtogetherunderthe label. Indeed,the varietyof researchreportedin conferencepapers,journalarticles,andbooks suggeststhatdesigncontinuesto expandin its meaningsand connections,revealingunexpecteddimensionsin practiceas well as understanding.This follows thetrendof designthinkingin the twentiethcentury,for we haveseento afielddesigngrowfroma tradeactivityto a segmentedprofessionfor technicalresearchandto what now shouldbe recognizedas anew liberalart of technologicalculture.It may seem unusualto talk about designas a liberalart,particularlywhen many people are accustomedto identifying theliberalartswith the traditional"artsand sciences"that are institutionalizedin colleges and universities.But the liberalarts areundergoinga revolutionarytransformationin twentieth-centuryculture, and design is one of the areasin which this transformationis strikingly evident.To understandthe change that is now underway, it is importantto recognize that what are commonly regarded as the liberal artstoday are not outside of history. They originatedin the Renaissanceand underwentprolonged development that culminatedin the nineteenth century as a vision of an encyclopedic educationof beaux arts,belles lettres,history, various naturalsciences and mathematics,philosophy, and the fledgling social sciences. This circle of learningwas divided into particular subject matters, each with a propermethod or set of methods suitable to its exploration. At their peakas liberal arts, these subject matters provided an integrated understandingof human experienceand the arrayof availableknowledge.By the end of the nineteenth century, however, existing subjectswere explored with progressively more refined methods, and newsubjects were added to accord with advances in knowledge.

1) From Richard McKeon, "TheTransformation of the Liberal Arts inthe Renaissance," Developments inthe Early Renaissance, ed. Bernard S.Levy (Albany: State University ofNew York Press, 1972), 168-69.2) Neo-positivism, pragmatism, and various forms of phenomenology havestrongly influenced design educationand practice in the twentieth century.If design theory has often tendedtoward neo-positivism, design practice has tended toward pragmatismand pluralism,with phenomenologistsin both areas. Such philosophical differences are illustrated in the split thatdeveloped between the theoreticalandstudio courses at the Hochschule furGestaltung (HfG) Ulm before its closing. The split between theory andpracticein design is an echo of the difference between the predominantlyneo-positivist philosophy of scienceand the exceptionally diverse philosophies of practicing scientists. Designhistory, theory, and criticism couldbenefit from closer attention to thepluralism of views that guide actualdesign practice.3) Walter Groupius was one of the first torecognize the beginnings of a new liberal art in design. In an essay writtenin 1937, he reflected on the foundingof the Bauhaus as an institutiongrounded on the idea of an architectonic art: "Thus the Bauhaus wasinaugurated in 1919 with the specificobject of realizing a modern architectonic art,which like human naturewasmeant to be all-embracingin its scope. Our guiding principle was thatdesign is neither an intellectual nor amaterial affair, but simply an integralpart of the stuff of life, necessary foreveryone in a civilized society." Scopeof Total Architecture (New York:Collier Books, 1970), 19-20. The term"architectonic,"in this case, transcendsthe derivative term "architecture" asit is commonly used in the modernworld. Throughout Western culture,the liberal arts have similarly beendescribed as "architectonic" becauseof their integrativecapacity. Groupiusappeared to understand that architecture, regardedas a liberalart in its ownright in the ancient world, was onlyone manifestation of the architectonic art of design in the twentiethcentury.4) John Dewey, The Quest for Certainty:A Study of the Relation of Knowledgeand Action (1929; rpt. New York:Capricorn Books, 1960), 290-91.6result,the circleof learningwas furtherdividedand subdivided,untilall thatremainedwas a patchworkquiltof specializations.Today, these subjectmattersretainan echo of theirold statusas liberalarts,buttheyflourishas specializedstudies,leadingto theperceptionof an evermorerichanddetailedarrayof factsandvalues.Althoughthesesubjectscontributeto theadvanceof knowledge,as they havebecomeprothey alsocontributeto its fragmentation,gressively narrow in scope, more numerous, and have lost"connectionwith eachotherandwith the commonproblemsandmattersof daily life from which they select aspects for precisemethodologicalanalysis."'The searchfor new integrativedisciplinesto complementthe artsandscienceshasbecomeone of thecentralthemesof intellectualandpracticallife in the twentiethcentury. Without integrative disciplines of understanding,communication,andaction,thereis littlehope of sensiblyextending knowledgebeyondthe libraryor laboratoryin orderto servethe purposeof enrichinghumanlife.The emergenceof designthinkingin the twentiethcenturyisimportantin this context.The significanceof seekinga scientificbasisfor designdoes not lie in the likelihoodof reducingdesigntoone or anotherof the sciences-anextensionof the neo-positivistprojectandstillpresentedin thesetermsby somedesigntheoristsRather,it lies in a concernto connectandintegrateusefulknowledge from the artsand sciencesalike,but in ways that are suitedto theproblemsandpurposesof thepresent.Designers,areexploring concreteintegrationsof knowledgethatwill combinetheorywith practicefor new productivepurposes,and this is the reasonwhy we turnto designthinkingfor insightinto the new liberalartsof technologicalcultureDesign and Intentional OperationsThe beginningof the study of designas a liberalartcan be tracedto the culturalupheavalthatoccurredin the earlypartof the twentieth century.The key featureof this upheavalwas describedbyJohnDewey in TheQuestforCertaintyas the perceptionof a newcenterof the universe.Theold centerof theuniversewasthemindknowingby,meansof anequipmentof nantecedentexternalmaterial equallycompletewithin itself. The new centerisindefiniteinteractionstakingplacewithin a courseofnaturewhichis notfixedandcomplete,butwhichis capable of directionto new anddifferentresultsthroughthemediationof intentionaloperations.WhatDewey describeshereis the root of the differencebetweenthe old andnew liberalarts,betweenspecializationin the factsof asubjectmatterandtheuseof new disciplinesof integrativethinking.

5) John Dewey, Experience and Nature(1929; rpt. New York: DoverPublications, Inc., 1958), 357.6) Dewey, Experience and Nature, 35758.International7) The neo-positivistEncyclopedia of Unified Science,which included Charles Morris'sFoundations of the Theory of Signs,also included Dewey's Theory ofValuation. However, Dewey's Logicwas ignored or ridiculed by neo-positivist logicians and grammarians.8) John Dewey, "By Nature and By Art,"Philosophy of Education (Problemsof Men) (1946; rpt. Totowa, NewJersey: Littlefield, Adams, 1958), 288.9) Dewey, "By Nature and By Art," 29192.Dewey observes,however,that the meaningand implicationsof the new directionarestill not fully understood.Nowadayswe havea messyconjunctionof notionsthatare consistentneitherwith one anothernor with thetenorof our actuallife. Knowledgeis still regardedbymostthinkersasdirectgraspof ultimatereality,althoughthepracticeof knowinghasbeenassimilatedto theprocedureof theusefularts;-involving,thatis to say,doingthat manipulatesand arrangesnaturalenergies.Againwhile science is said to lay hold of reality,yet "art"insteadof beingassigneda lowerrankis sfurther,Dewey exploresthe new relationshipbetweenscience,art,andpractice.He suggestsin Experienceand Nature that knowledgeis no longerachievedby directconformity of ideas with the fixed orders of nature;knowledge isachievedby a new kind of artdirectedtowardordersof change.Butif moderntendenciesarejustifiedin puttingartandcreationfirst, then the implicationsof this positionshouldbe avowedandcarriedthrough.It would thenbe seen that scienceis an art, that art is practice,andthatthe only distinctionworthdrawingis not betweenpracticeandtheory,but betweenthose modesof practice that are not intelligent, not inherently andimmediatelyenjoyable, and those which are full ofenjoyedmeanings.Althoughthe neo-positivistscourtedDewey for a time,it wasapparentthat his understandingof the developmentof scienceinthe twentiethcenturywas quite differentfrom theirunderstanding7.Insteadof treatingscienceas primaryand art as secondary,Dewey pointedtowardscienceas art.Theconsiderationthatcompletesthe groundfor assimilating science to art is the fact that assignment ofscientificstatusin oduced.Scienceis now the product of operationsdeliberatelyundertakenin conformitywith a planor projectthathasthepropertiesof a working hypothesis.WhatDeweymeansby "art"in thiscontextis crucialto understandculture.ingthenewroleof designandtechnologyin contemporaryAftera periodin crafts,scienceentereduponborrowinga periodof steadyandever-acceleratedgrowthby meansof deliberateinventionof such applianceson its ownaccount.Inorderto markthisdifferentialfeatureof theartwhichis science,I shallnow usetheword"technology.".

10) For Dewey, the artsof production,includethefinearts.He makesno sharpshadtinction betweenbeteen fineandusefuldistinctionarts.What Dewey defines as technology is not what is commonlyunderstoodin today'sphilosophyof technology.Insteadof meaning knowledgeof how to makeand use artifactsor the artifactsthemselves,technologyfor Dewey is anartof experimentalthinking. It is, in fact, intentionaloperationsthemselvescarriedout inthe sciences,the artsof production, or socialandpoliticalaction.We mistakenly identify technology with one particular type ofproduct-hardware-that may result from experimentalthinking, but overlookthe artthatlies behindandprovidesthe basisforcreatingother types of products.Fromthis perspective,it is easy to understandwhy designanddesign thinkingcontinueto expandtheir meaningsand connections in contemporaryculture.Thereis no areaof contemporarylife wheredesign-the plan,project,or workinghypothesiswhichconstitutesthe "intention"in intentionaloperations-is not a significantfactorin shapinghumanexperience.Design evenextendsinto the coreof traditionalscientificactivities,whereit is employedto cultivate the subject mattersthat are the focus of scientificcuriosity.But perceivingthe existenceof such an art only opensthe door to furtherinquiry, to explainwhat that art is, how itoperates,andwhy it succeedsor failsin particularsituations.Thechallengeis to gaina deeperunderstandingof designthinkingsothat more cooperation and mutual benefit is possible betweenthosewho applydesignthinkingto ill helpto makethepracticalexplorationof design,particularlyin the artsof production,more intelligentand meaningful.However,a persistentproblemin this regardis thatdiscussionsbetweendesignersand membersof the scientificcommunitytendto leavelittle room for reflectionon the broadernatureof designandits relationto the artsand hegeneralpublicthatultimatelying,marketinguses the resultsof designthinking.Insteadof yieldingproductiveintegrations,the resultis oftenconfusionanda breakdownof communication,with a lack of intelligentpracticeto carryinnovativeideasinto objective,concreteembodiment.In turn,thisundermineseffortsto reacha clearerunderstandingof designitself,sometimesdrivingdesignersbackinto a defenseof theirwork in the contextof ionto cipants,amongis littlehope of understandingthe foundationsandvalueof designthinkingin an increasinglycomplextechnologicalculture.The Doctrine of PlacementsBy "liberalart"I meana disciplineof thinkingthatmaybe sharedto some degreeby all men andwomen in their daily lives and is,in turn,masteredby a few peoplewho practicethe eit to new areasof inno8

21) Althoughstilla common andusefulwayof studying visual communication,thisapproachhaslost some of its initialforcein actualdesign practicebecause it hasmoved into personalidiosyncracyandasearchfor novelty,which often distractsone from the central tasks of effectivecommunication. This is evident, forexample,amongthose graphicdesignerswho have made pedestrianreadingsofdeconstructionist literary theory therationalefor their work. Visual experimentationis an importantpartof graphicdesign thinking, but experimentationmust finallybe judgedby relevanceandeffectivenessof communication.For adiscussionof the limitsof semioticsanddesign, see Seppo Vakeva, "What DoWe Need Semiotics For?," SemanticVisions in Design, ed. Susann Vihma(Helsinki:Universityof IndustrialArtsUIAH, 1990),g-2.22) Swiss graphicdesignerRuedi Ruegg hasrecently spoken of the need for morefantasy and freedom in graphicdesignthinking.

Recently,however,a new approachin graphicdesignthinkinghasbeguntoquestionthe essentiallylinguisticor grammaticalapproachof communications theory and semiotics by regarding visualcommunicationaspersuasiveargumentation.As thisworkunfolds,it will likely seek to repositiongraphicdesignwithin the dynamic flow of lationshipsamonggraphicdesigners,audiences,andthe contentof communication.In this situation,designerswould no longerbeviewedas individualswho decoratemessages,but as communicators who seek to discoverconvincingargumentsby meansof anew synthesisof imagesandwords.
