INTRODUCTION Friedrich Hayek (1899–1999), one of the great intellectuals of the 20th century, is widely known for his contributions to economics and to the social sciences in general. For several decades, his ideas have attracted widespread interest and have wielded a strong and enduring influence on otherscholarsinareasthatcomfortablyfitundertherubricof‘‘economics, politics, and philosophy.’’ Hayek was a prolific scholar (29 volumes are plannedforhisCollectedWorksbytheUniversityofChicagoPress)andthe secondary literature on Hayek in vast.1 His work in technical economics, beginning in the late 1920s, and his extensive writings in broader social theory still cast a robust and relevant light on the many issues centering on the operation of the market economy and social institutions and processes. It is especially useful for the purpose at hand to reaffirm that much of Hayek’sworkinthesocialsciencestypicallyaddresses,directlyorindirectly, questions and problems of the nature, transmission, and use of knowledge. Curiously, Hayek’s work in cognitive psychology, which falls within the province of such questions, has not been as widely studied by Hayek scholars.Theaimofthisvolumeistoexplorepossibleconnectionsbetween Hayek’s cognitive psychology and social theories, hence thetitle The Social ScienceofHayek’s‘‘TheSensoryOrder.’’ItwillshowthatHayek’scognitive theory has, unexpectedly and despite its being virtually ignored for many years, begun to inspire a wide range of endeavors to mine its insights to better understand social phenomena. HISTORICAL COMMENTS ON THE SENSORY ORDER Publishedin1952(butbasedonanexploratoryessaywrittenasastudentin 1920), The Sensory Order remained generally unnoticed by psychologists, philosophers,socialscientists,andHayekscholarsforthenextfewdecades. Hayek’s Nobel Prize in 1974 helped induce a resurgence of interest around the world in his economics and broader social theory, but it was chiefly The UnexpectedFertility of Hayek’s CognitiveTheory 3 cognitive psychologist Walter B. Weimer who should be credited for bringing Hayek’s cognitive work before a larger audience and making the case for its wider significance for economics and social theories generally. Beginning in the mid-1970s, Weimer (1979) started using and developing the ideas in The Sensory Order for his work in cognitive science and the methodology of scientific research. Coming from a background in the philosophy of science, he was especially influenced by the late W.W. Bartley’s The Retreat to Commitment (1962) and Kuhn’s The Structure of Scientific Revolutions (1970) in seeing Hayek’s work in cognitive science, constraints on knowledge, and spontaneous order, as compatible to Bartley’s epistemological stance on ‘‘comprehensively critical rationalism’’ and Kuhn’s evolutionary theory of science. In 1981, Weimer organized a cognitivescienceconferenceatPennStateUniversitythatfeaturedHayekas the principal speaker (Hayek, 1982), while Weimer’s own address (Weimer, 1982)presentedthecaseforthesignificanceofHayek’scognitivepsychology for the social sciences; this paper became the preeminent, and for several years the only useful entre´e to The Sensory Order. Interest in Hayek’s cognitive theory, however, was not completely moribund in the period after 1980. Aside from Weimer’s continued work,2 we can take note that several notable neurophysiologists such as Gerald Edelman (1985) and Joaquin Fuster (1995) specifically highlighted the prescientideasputforthbyHayek,particularlywithrespecttoevolutionary neuromechanisms. In the social sciences, Yeager (1984) seems to have been the first economist to seriously apply Hayek’s writings on cognitive psychology to economics. In his short paper, Yeager sought to establish thepropositionthat‘‘appreciatingHayek’sworkineconomicsandpolitical science requires knowing of his interest in psychology’’ (p. 2). To make his point, Yeager centered his attention on The Road to Serfdom. The connections Yeager forged are based on the ‘‘insights of ‘literary’ psychology’’ exhibited in The Road to Serfdom regarding ‘‘the influence of beliefs and attitudes’’ as opposed to the more technical treatment of cognitive processes found in The Sensory Order (p. 3). While Yeager’s discussion of the The Sensory Order is an excellent introductiontoHayek’scognitivetheoryandallthemoreremarkablegiven its brevity, the overall cast of the paper illustrates an especially vexing questiondoggingtheliteratureonTheSensoryOrderbysocialscientists:Do we need The Sensory Order at all to do our social science and how does it make a difference in providing insight toward understanding the social realm? Yeager’s paper, which sadly made no identifiable impact on other economists until about 2003,3 plus three other papers to be noted 4 WILLIAM N. BUTOS immediately below, illustrate the several directions researchers subsequent to Weimer have pursued in attempting to understand and develop the implications of The Sensory Order. First,ManfredStreit(1993)4brokenewgroundinaregrettablyneglected paper by giving an extended overview of Hayek’s work in epistemology as presented in The Sensory Order and an argument for its foundational significance for his economic and social theories. The relevant connections Streit suggested include cognitively grounded subjectivity, limitations on individual knowledge, and the significance of tacit (or unconscious) knowledge. These elements from Hayek’s cognitive theory, Streit main- tained, provide central ideas upon which it is possible to construct a theoretically coherent Hayekian social theory. In the second paper, Butos and Koppl (1993) used The Sensory Order to generate a theory of ‘‘Hayekian economic expectations’’ that are coherent, competitive, and self-correcting, and which are the result of cognitive processes that embody learning and the capacity to formulate conjectures andself-correctiveroutinesthatallowtheindividualtoadapttotheexternal environment. The thrust of this and related subsequent research (see, e.g., Butos & Koppl, 1997) was to demonstrate that a judicious application of insightsgleanedfromHayek’scognitivetheorycouldbeusefulinaddressing questions and issues in economics. A third and related direction is reflected in the attempt to explore the systemicimplicationsofHayek’swork,incorporatingtheideasofevolution and self-organization. McQuade (2007), for example, saw The Sensory Order as providing a ‘‘prototypical description of an adaptive classifying system’’ (p. 58) useful for understanding the social orders of science and market. The key point of intersection is that both the brain and other emergent (or spontaneous) orders, such as science and the market, ‘‘implement a classifying process’’ as a byproduct of the ‘‘interactions betweentheircomponents’’thatinduce‘‘adaptivereactionsofthesystemas a whole’’ (p. 59). ThesepapersofYeager,Streit,ButosandKoppl,andMcQuadeillustrate the breadth and variety of the secondary literature on Hayek’s cognitive theory in economics and broader social theory. This literature, which has nowgrownquitelarge,canbesortedintotwodistinctyetoftenoverlapping paths. One path has followed the work of Yeager and Streit in the sense of using The Sensory Order to better understand Hayek’s oeuvre. This approach, amply demonstrated by scholarship through Caldwell (2004), provides an assessment and appreciation of the deep and wide-ranging insightsofoneofthe20thcentury’sintellectualgiants.Animportantpartof The UnexpectedFertility of Hayek’s CognitiveTheory 5 this literature, as evidenced, for example, in Streit’s paper, may be seen as reflecting the broader interests of political economy in which connections are drawn for Hayek’s own thinking across various domains of inquiry in someratherfundamentalways.Animportantcontributionofthisliterature hasbeentoestablishthecontinuityinHayek’sownthinking(see,e.g.,Gray, 1984;Birner,1994;Butos&McQuade,2002;Steele,2007).Butasignificant aspectofactuallyestablishingthecoherenceofHayek’sideashasquiteoften involved the relevance of his cognitive work for methodological concerns (see Birner, 1999; Caldwell, 2004). In this area, there is little disagreement among researchers of the significance for social science methodology of Hayek’s cognitive work regarding subjectivism (or at least some variant of it), constraints on knowledge, and the nature and limits of prediction. The second, and as yet less traveled, path, illustrated by the work of Butos, Koppl, and McQuade, seeks to stand on Hayek’s shoulders in applying insight gleaning from The Sensory Order to push forward the understanding of social phenomena. These two paths of inquiry, both emanating from ideas in The Sensory Order, have, since the early 1990s, generated a small but nonetheless fairly regular stream of papers and books by economists and others who have beenatpainstoexplainHayek’sideasinthisareaandinseveralcaseshave pursued the application of those ideas to significant questions in social science.Slowly,Hayek’sideashavebeenmademorefamiliarandaccessible to a wider audience. Although I will briefly highlight the basic gist of Hayek’s cognitive theory below, I will do so in a way that gears the discussion to the application of those ideas from the standpoint of social theory and economics. Hopefully, this will direct the reader’s attention toward questions inspired by The Sensory Order that bear on both the theory of agency (at the individual level) and market and, more generally, social theory (at the level of the emergent phenomena generated by groups of individuals). AN OVERVIEW OF HAYEK’S COGNITIVE THEORY The objective of this volume is not to rehash or assess Hayek’s cognitive theory but to provide some insight into whether and in what ways that theory may be of value to social scientists. This approach, it is hoped, will redirectattentiontowardquestionsthatmatterforsocialscientistsandaway fromquestionsthatconcerntheneurophysiologyofthebrain.Theaimisto address the question posed above – to show that Hayek’s cognitive theory
