The book’s core argument is that an artificial intelligence that could equal or exceed human intelligence—sometimes called artificial general intelligence (AGI)—is for mathematical reasons impossible. It offers two specific reasons for this claim: Human intelligence is a capability of a complex dynamic system—the human brain and central nervous system. Systems of this sort cannot be modelled mathematically in a way that allows them to operate inside a computer. In supporting their claim, the authors, Jobst Landgrebe and Barry Smith, marshal evidence (...) from mathematics, physics, computer science, philosophy, linguistics, and biology, setting up their book around three central questions: What are the essential marks of human intelligence? What is it that researchers try to do when they attempt to achieve "artificial intelligence" (AI)? And why, after more than 50 years, are our most common interactions with AI, for example with our bank’s computers, still so unsatisfactory? Landgrebe and Smith show how a widespread fear about AI’s potential to bring about radical changes in the nature of human beings and in the human social order is founded on an error. There is still, as they demonstrate in a final chapter, a great deal that AI can achieve which will benefit humanity. But these benefits will be achieved without the aid of systems that are more powerful than humans, which are as impossible as AI systems that are intrinsically "evil" or able to "will" a takeover of human society.

This book consists of a dialogue between two interlocutors, Pablo and a student, who discuss a great range of issues in social philosophy and political theory, and in particular, the emergence, working properties and economic effects of institutions. It uses the dialogical form to make philosophy more accessible, but also to show how ideas develop through intellectual interaction. The fact that one of the interlocutors is the "student" in a place in the real world makes the dialogue quasi-fictive in character (...) and enables the active engagement of the reader. After all, we are all philosophers and we develop our own philosophy by exchanging views and arguments. The dialogue form is and should remain the principal form of philosophizing, since ideas, like butterflies, do not merely exist – they develop. This is certainly the case in actual philosophical interaction, and it can be the case in written philosophical exposition. Although the dialogue does not presuppose prior acquaintance with the respective philosophical and social scientific literature under discussion in this book, it makes arguments more accessible, and conveys the feeling that there are no definite solutions to philosophical problems.

University of North Carolina at Greensboro Most approaches to the philosophy of the natural and social sciences are basedon completed scientific investigations. However, there are many importantcases in science in which testing is incomplete. These cases are termed suspendedtrials and are particularly significant in biomedical and allied health fields. Initially,the authors' interest in suspended trials was piqued by a controversialmethod for assisting autistic children known as facilitated communication. Thisarticle examines facilitated communication and other examples of suspendedtrials from the perspective of (...) an economics of science and game theory. Themodel is consistent with recent evolutionary approaches to the philosophy ofthe natural and social sciences and with recent contributions to an economicunderstanding of science.

Wants and desires are central to ordinary experience and to aesthetic, philosophical, and theological thought. Yet despite a burgeoning interest in the history of emotions research, their history as objects of scientific study has received little attention. This historiographical neglect mirrors a real one, with the retreat of introspection in the positivist human sciences of the early 20th century culminating in the relative marginalization of questions of psychic interiority. This article therefore seeks to explain an apparent paradox: the attempt to (...) develop a comprehensive theory of ‘why … we want what we want’ in the 1940s by esteemed American ‘neo-behaviorist’ psychologist Edward Tolman – a proponent of a methodology famous for its prohibition on appeals to unobservable mental phenomena. Though chiefly known today for his theory of ‘cognitive maps’, Tolman also sought to map the contours of desire as such, integrating Freudian and behaviorist models of the ‘drives’ to develop a complex iconography of the universal structures of motivation. Close attention to Tolman's striking maps offers a compelling limit case for what could and could not be captured within an anti-mentalist framework, and illuminates an important precursor to theories of motivational ‘affect’ in the postwar cognitive and neurosciences. His work upsets a standard chronology that centers on the ‘cognitive revolution’ of the 1960s, and points to the significance of psychoanalysis to an earlier turn to cognitivism. Tolman concluded his theory pointed ‘in the direction of more socialism’ – a reminder of the politically labile anti-essentialism of behaviorism's commitment to mental plasticity. (shrink)

Theories of institutions can be classified into two broad approaches: institutions-as-rules and institutions-as-equilibria. According to the first approach, institutions are conceived as rules that guide the actions of individuals engaged in social interactions. On the other hand, the second approach views institutions as behavioral patterns. In order to have a complete picture of institutions, we need to take both approaches into consideration. Individuals construct mental models to produce expectations about institutions, while institutions make individual expectations relatively compatible. The main purpose (...) of this paper is to develop a general framework within which it is possible to analyze coevolution of individual mental models and institutions. (shrink)

The article focuses on the anti-naturalism of Menger and Mises. It presents a methodological approach formulated by both scholars as stemming from epistemological anti-naturalism and demonstrating similarities to social phenomenology. The article also discusses the development of the anti-naturalistic perspective on the basis of Hayek’s conception of sensory order. The latter allowed addressing the problem of validity of methodological dualism and established a sound foundation for the methodological approach of the Austrian School of Economics.

This article attempts a self-clarification of practice theory by providing a genetic history of ‘practice’ as a figure in social thought. This locates two different versions of practice theory in Marx’s ‘practical question’ and Hobbes’ ‘Kingdom of Darkness’, respectively, and shows how both historically comprise a practical critique of testing reason. This article examines how the practical critique performs a dialectic of politicization and depoliticization that finds family resemblances and paradoxical alignments between the political left and right. The article evaluates (...) the strength of the practical critique and asks whether it results in a power politics with both left and right versions. (shrink)

Neural activity and social activity share close parallels, particularly the fact that spontaneous adaptations are paramount in both realms. Environmental pressures require organisms and societies to adapt to new and uncertain situations. Adaptations create, respectively, stronger neural and social networks that may, in turn, make the system more resilient to future uncertainties—but only if the adaptations are beneficial to the system.

This book is a survey of the most important developments in Austrian philosophy in its classical period from the 1870s to the Anschluss in 1938. Thus it is intended as a contribution to the history of philosophy. But I hope that it will be seen also as a contribution to philosophy in its own right as an attempt to philosophize in the spirit of those, above all Roderick Chisholm, Rudolf Haller, Kevin Mulligan and Peter Simons, who have done so much (...) to demonstrate the continued fertility of the ideas and methods of the Austrian philosophers in our own day. For some time now, historians of philosophy have been gradually coming to terms with the idea that post-Kantian philosophy in the German-speaking world ought properly to be divided into two distinct traditions which we might refer to as the German and Austrian traditions, respectively. The main line of the first consists in a list of personages beginning with Kant, Fichte, Hegel and Schelling and ending with Heidegger, Adorno and Bloch. The main line of the second may be picked out similarly by means of a list beginning with Bolzano, Mach and Meinong, and ending with Wittgenstein, Neurath and Popper. As should be clear, it is the Austrian tradition that has contributed most to the contemporary mainstream of philosophical thinking in the Anglo-Saxon world. For while there are of course German thinkers who have made crucial contributions to the development of exact or analytic philosophy, such thinkers were outsiders when seen from the perspective of native German philosophical culture, and in fact a number of them found their philosophical home precisely in Vienna. When, in contrast, we examine the influence of the Austrian line, we encounter a whole series of familiar and unfamiliar links to the characteristic concerns of more recent philosophy of the analytic sort. As Michael Dummett points out in his Origins of Analytic Philosophy, the newly fashionable habit of referring to analytic philosophy as "Anglo-American" is in this light a "grave historical distortion". If, he says, we take into account the historical context in which analytic philosophy developed, then such philosophy "could at least as well be called "Anglo-Austrian" (1988, p. 7). Much valuable scholarly work has been done on the thinking of Husserl and Wittgenstein, Mach and the Vienna Circle. The central axis of Austrian philosophy, however, which as I hope to show in what follows is constituted by the work of Brentano and his school, is still rather poorly understood. Work on Meinong or Twardowski by contemporary philosophers still standardly rests upon simplified and often confused renderings of a few favoured theses taken out of context. Little attention is paid to original sources, and little effort is devoted to establishing what the problems were by which the Austrian philosophers in general were exercised -- in spite of the fact that many of these same problems have once more become important as a result of the contemporary burgeoning of interest on the part of philosophers in problems in the field of cognitive science.

If we are eventually to understand the capability of higher organisms for perceptual recognition, generalization, recall, and thinking, we must first have answers to three fundamental questions: 1. How is information about the physical world sensed, or detected, by the biological system? 2. In what form is information stored, or remembered? 3. How does information contained in storage, or in memory, influence recognition and behavior? The first of these questions is in the.

The paper begins by providing a game-theoretic reconstruction of Gilbert’s (1989) philosophical critique of Lewis (1969) on the role of salience in selecting conventions. Gilbert’s insight is reformulated thus: Nash equilibrium is insufficiently powerful as a solution concept to rationalize conventions for unboundedly rational agents if conventions are solutions to the kinds of games Lewis supposes. Both refinements to NE and appeals to bounded rationality can plug this gap, but lack generality. As Binmore (this issue) argues, evolutive game theory readily (...) explains the origin of conventional behavior, but that is not Lewis’s project. Gilbert’s critique is generalized by reference to Bacharach’s (2006) work on team reasoning in games. The paper then argues that although Lewis’s account of the rationalization of conventions is shown by the reconstruction of Gilbert’s critique to be incomplete, Gilbert is wrong to conclude that classical (‘eductive’) game theory lacks the resources to explain conformity to conventions among people. A game-theoretic account of the dynamics of socialization, based on Ross’s (2005, 2006) idea of ‘game determination’, rationalizes choices of conventional strategies in overlapping generations contexts, provided agents are products of evolutionary selection and know that other players are also such products.

The article is an evaluation of the economic, organizational and social theory of Luc Boltanski and Eve Chiapello’s The New Spirit of Capitalism 15 years after its publication. The role of network capitalism, state capitalism, and aesthetic capitalism in French social life is analysed. The article concludes that flexible network capitalism was largely a chimera of the 1990s and that French political and economic life today is dominated by an ailing state capitalism.

This paper studies the attempts (and failure) of Russian revolutionaries to mobilize the peasantry in the decade leading to the Soviet revolution of 1917. Peasants, who had been emancipated from serfdom only four decades earlier, in 1861, were still largely propertyless and poor. This would, at first glance, make them a ripe target for revolutionary activity. But peasants were largely refractory. We explain this lack of revolutionary spirit through two models. First, despite their lack of education and political awareness, the (...) peasants were rational in their refusal to participate in revolutionary activity; they engaged in a cost–benefit calculus which pushed them away from revolt and political organization. Second, based on the Wildavsky–Thompson cultural types, Russian peasants were largely fatalist: they believed they had no influence on the world, so it was not worth attempting to change it. This paper sheds light on some aspects of the Russian revolution, but also encourages further research in history and economic sociology on the interaction between culture and incentives. (shrink)

The paper analyzes the sacred foundations of Western institutional order, moving from an epistemological, historical and legal–aesthetic perspective. Firstly, it identifies an epistemological theory of complexity which, pursuing Hayek’s theory of complexity, Robilant’s notion of informative–normative systems, Popper’s theory of the Worlds, and Dupuy’s theory of endogenous fixed point, will conclusively lead to presenting the hypothesis of World 0 as the World of the foundation of legal thinking, the home of the sacred and the aesthetic. Secondly, it identifies the axiological (...) character of the legal aesthetic as a discipline, a topic that will be taken up in relation to the work of the French historian of canonical law and psychoanalyst Legendre, starting from the analysis of a legal/historiographical context (Corpus Iuris Civilis, Corpus Iuris Canonici, Hobbesian Leviathan, Kelsenian Grundnorm). Thirdly, following Ellul’s thought on secularization, the idea that we now live in a secularized, lay society, lacking in the sacred is revealed as a sort of illusion, the creation of a myth of modernity, only apparently rational. Finally the paper proposes as the task of legal theory the identification of the system of “nomograms” in which the normative message is organized, according to a nonreductionistic approach that forces legal theory to recognize the plurality of the iconic forms of the normative message. The “nomograms” respond to the need of extending the field of legal science to phenomena that the positivist theory of law does not consider important, but which the process of evolution of contemporary society imposes.

This paper shows how business ethics as a concept may be approached from a cognitive viewpoint. Following F. A. Hayek''s cognitive theory, I argue that moral behavior evolves and changes because of individual perception and action. Individual moral behavior becomes a moral rule when prominently displayed by members of a certain society in a specific situation. A set of moral rules eventually forms the ethical code of a society, of which business ethics codes are only a part. By focusing on (...) the concept of "limited" or "dispersed knowledge" that underlies the cognitive approach, I show that universal ethical norms that should lead to defined outcomes cannot exist. This approach moreover shows the limits of deliberate rule-setting. Attempts to deliberately impose universal ethical rules on societies may turn out to be harmful for societal development and lead to an abuse of governmental power. (shrink)

F.A. Hayek’s theory of cultural evolution has often been regarded as incompatible with his earlier works. Since it lacks an elaborated theory of individual learning, we try to back his arguments by starting with his thoughts on individual perception described in his Theory of Mind. With a focus on the current discussion concerning biological and cultural selection theories, we argue his Theory of Mind leads to two different stages of societal evolution with well-defined learning processes, respectively. The first learning process (...) describes his Morality of Small Groups, in which Hayek’s thoughts coincide with learning theories that do not allow for the perception of behavior from outside the group. His second stage of cultural evolution, the Open Society, involves a different kind of learning behavior. We connect this notion with a model of local interaction in which the cultural learning aspect is addressed by a distinction between interaction and learning neighborhoods. This results in a situation in which individuals change their strategy and —depending on the radius of interaction and learning neighborhood—eventually may adopt new strategies that lead to higher payoffs.

To understand the work of economic theorists it is often helpful to situate it in the context of the rhetorical strategy they were pursuing. Two ontologically distinct rhetorical strategies of laissez-faire may be distinguished by the way they articulate the individual interest with the general interest. A reductionist approach, exemplified by Friedman and Lucas, suggests that the properties and behaviour of an entity can be understood in terms of the properties and behaviour of the constituent lower-level components, taken in isolation. (...) The contrary – holistic – stance, viewing the qualities of phenomena as products of the inter-relations between their component parts, is characteristic of Smith and Hayek. While the reductionist approach naturally issues in a laissez- faire policy prescription, the holistic account is more problematic. Reconciling a holistic ontology with a reductionist policy prescription requires the intercalation of a black box, such as an evolutionary process or the invisible hand of a deity. (shrink)

A sensible quality is a perceptible property, a property that physical objects (or events) perceptually appear to have. Thus smells, tastes, colors and shapes are sensible qualities. An egg, for example, may smell rotten, taste sour, and look cream and round.1,2 The sensible qualities are not a miscellanous jumble—they form complex structures. Crimson, magenta, and chartreuse are not merely three different shades of color: the first two are more similar than either is to the third. Familiar color spaces or color (...) solids capture, to a greater or lesser extent, these relations between the colors. The same goes for sensible qualities perceived in other modalities: middle C, high C, and D are not merely three different notes, and the taste of lemons, oranges, and sugar cubes are not merely three different tastes. How can this structure of appearance be explained? One idea is that sensible qualities are of two sorts: basic and derived. The basic sensible qualities are the building blocks from which the derived sensible qualities can be.. (shrink)

Some current attempts to go beyond the narrow scope of rational choice theory (RCT) in the social sciences and the artificial reconstructions it sometimes provides focus on the arguments that people give to justify their beliefs and behaviors themselves. But the available argumentation theories are not constructed to fill this gap. This article argues that relevance theory, on the contrary, suggests interesting tracks. This provocative idea requires a rereading of Sperber and Wilson's theory. Actually, the authors do not explicitly support (...) RCT, and Sperber has even strongly criticized methodological individualism, which most of the time underlies RCT, in favor of infra-individualism. A key point of the argument presented here is to show that Sperber and Wilson do not firmly distinguish between infra-individualism and subintentionality. Only subintentionality is needed. Key Words: argumentation • rational choice • relevance theory • methodological individualism. (shrink)

A Notional Level of Cognitive Distortions in Depression: Does It Exist? A Voice for Interdisciplinarity in Studying Cognitive Functioning of Individuals with Depressive Disorders This aritcle raises the problem of cognitive depressive distortions observed at the notional level. It relates to recent neuropsychological, psychological, and linguistic studies, taking an interdisciplinary theoretical perspective, and illustrating the advantages of interdisciplinarity in modern psycholinguistic projects. It shows that, generally, the notional level has been neglected in psychopathological and psychological research on depressive functioning. The (...) problem is described with reference to linguistic and psycholinguistic theories linking language with cognition. Particular emphasis is devoted to theories and methods of metaphorical processing analysis which, taking into account the similarities between cognitive functions engaged in understanding metaphors, and those disordered as a result of depression, seem to be an adequate frame to study the problem. The text ends with a proposal of an interdisciplinary research project dedicated to the study of metaphorical conceptualizations of some notions created by people suffering from depression. (shrink)

The concept of an ecological niche (econiche) has been used in a variety of ways, some of which are incompatible with a relational or functional interpretation of the term. This essay seeks to standardize usage by limiting the concept to functional relations between organisms and their surroundings, and to revise the concept to include epistemic relations. For most organisms, epistemics are a vital aspect of their functional relationships to their surroundings and, hence, a major determinant of their econiche. Rejecting the (...) traditional dualism of organism and environment, an econiche is defined as the reciprocal (dual) of a functionally specified class of organisms (FSTU). From this perspective, an econiche necessarily implies a certain type of organism, and a class of functionally similar organisms implies a special econiche.The econiche concept is also discussed in relation to other ecological terms that reflect the distributional patterns of organisms, such as habitat, and the concept of an empty niche is criticized.

This volume is about the many ways we perceive. Contributors explore the nature of the individual senses, how and what they tell us about the world, and how they interrelate. They consider how the senses extract perceptual content from receptoral information. They consider what kinds of objects we perceive and whether multiple senses ever perceive a single event. They consider how many senses we have, what makes one sense distinct from another, and whether and why distinguishing senses may be useful. (...) They consider the extent to which the senses act in concert, rather than as discrete modalities, and whether this influence is epistemically pernicious, neutral, or beneficial. They explore both the familiar five sense modalities and other candidate sense modalities, including a sense for flavour, inner senses (e.g., a sense for pain), and various senses that may result from using sensory substitution devices. Contributors often represent competing views, and the methods they deploy sometimes differ from one essay to the next—with some drawing upon the sciences and engineering and others relying upon conceptual analysis. All contributors agree, nonetheless, that traditional theorizing about the senses is hampered by a neglect of the senses other than vision, and by the misconception that vision is a passive receptacle for an image thrown by a lens. And many contributors believe that it is unduly restrictive to think of perception as a collation of contents provided by individual sense modalities; they think that to understand perception properly, we need to build into our accounts the idea that the senses work together. The ambition of the volume is to begin to develop better paradigms for understanding the senses, and thereby to move toward a better understanding of perception. (shrink)

This paper is part of the general debate about the need to rethink economics as a human discipline using a heuristic to describe its object, about the need to explicitly reject the positivistic approach in neoclassical economics, and about the urgency to adopt a different methodology, grounded on a realistic set of initial assumptions able to cope with the complexity of the decision making process. The aim of this paper is to show the use of Occam's razor in the economic (...) debate around realism in economic modelling. Occam's razor can be intended as a principle of logic that emphasises simplicity, or as a heuristic tool that emphasises parsimony. Neoclassical economists, such as Samuelson, have explicitly used Occam's razor as a logical principle to highlight the strict logic and simplicity of neoclassical economics; neoclassical models, however, are based on unrealistic assumptions. Some approaches of heterodox economics, au contraire, have used Occam's razor as a powerful heuristic tool to emphasise parsimony, building up models grounded on realistic initial assumptions and capable of embedding complexity into the general explanation of economic behaviour, as in Simon's bounded rationality (1955; 1957) and Hayek's notion of human rationality (1948; 1952; 1974) and cultural and social evolution (1967; 1978).

In his book The Sensory Order, Hayek anticipates many of the central ideas behind what we now call the connectionist paradigm, and develops on this basis a theory of the workings of the human mind that extends the thinking of Hume and Mach. He shows that the idea of neural networks is can be applied not only in psychology and neurology but also in the sphere of economics. For the mind, from the perspective of The Sensory Order, is a dynamic, (...) relational affair that is in many respects analogous to a market process. The mind, as Hayek puts it, is a 'continuous stream of impulses, the significance of each and every contribution of which is determined by the place in the pattern of channels through which they flow' , so that the flow of representative neural impulses can be compared 'to a stock of capital being nourished by inputs and giving a continuous stream of outputs'.

For many economists, including those who have made the most marked contribution to the development of the discipline, their work has to be understood in the context of the rhetorical strategy they were pursuing – what they wanted to persuade us of and how they wanted to do it. The paper identifies two fundamental rhetorical strategies of laissez-faire resting on entirely distinct ontological foundations. What distinguishes these two strategies is the way they articulate the individual with the general interest, how (...) they relate the micro to the macro. The two strategies discussed in the paper are characterised by the stance they take on a fundamental ontological issue, the way in which the things which appear to us in the world are related to the things or matters which compose them. A reductionist approach suggests that we can understand an entity at one level as a congeries. An entity in this view is just an aggregate of entities at a lower, substrate level – a purely external unity. The properties and behaviour of an entity can then be understood in terms of the properties and behaviour of the constituent lower-level components, taken in isolation. In this approach, phenomena at some level are regarded as having just the qualities enjoyed by its lower-level, substrate elements, writ large. The contrary, holistic, stance is to view the qualities of phenomena at one level as emergent at that level, and to assert that an entity can be understood as a product of the inter-relations between its component parts. We have, then, a pair of contrasted approaches: a polarity which is productive in the study of schools of thought, of competing methodologies, and of rhetorical strategies in economics. The paper applies this approach to the work of Smith, Keynes, Hayek, Lucas and Friedman. (shrink)

The article is devoted to the re-problematisation of F.A. Hayek's legacy in philosophy of law and social theory. Taking as an example the works of SPSU professor I.Y. Kozlikhin, and some other works about Hayek's theory of law, the author demonstrates several inadequacies of the current literature on Hayek's legal philosophy. In criticizing these highly debatable approaches, the author describes multiple but rarely considered nuances of Hayek's conception of law, which seem to be necessary for adequate understanding of his works. (...) In the author's view, only these details allow to cast some doubt on stereotypes about Hayek as a sort of “liberal ideologist” and unfold the true original potential of his philosophy. The main hypothesis of the article is that the key to this original potential lies not in Hayek's theory of freedom and market, but in his fundamental epistemological views. The ideal of freedom is not enough to discriminate between what is “just law” and what is not in hayekian theory. Only by the means of Hayek's epistemology we can separate law as “rules of just conduct” from other types of social institutions in his theory. This separation is based on broader epistemological separation of “simple” and “complex” phenomena in Hayek's theory of knowledge, which is reflected in his distinction between “organization” and “spontaneous order”. Since only the last of them represents a «complex phenomenon», it means that only a system of special meta-rational rules of conduct can provide an epistemically restricted social actor with an ability to act effectively in such a complex and rationally unknowable social structure. It is argued that only this “technical” capacity of meta-rational just law can be seen as the true basis of Hayek's theory of law. Neither hayekian theory of freedom, nor his theory of market can shed light on the Hayek’s most important and original contribution in the domain of legal theory. It is Hayek's epistemology that can be seen as the ultimate foundation of his conception of lawn. (shrink)

There occurred in the twentieth century the most remarkable episode in the history of human thought. A number of thinkers denied the existence of something we know with certainty to exist: consciousness, conscious experience. Others held back from the Denial, as we may call it, but claimed that it might be true --a claim no less remarkable than the Denial. This paper documents some aspects of this episode, with particular reference to two things. First, the development of two views which (...) are forms of the Denial --philosophical behaviourism, and functionalism considered as a doctrine in the philosophy of mind-- from a view that does not in any way involve the Denial: psychological methodological behaviourism. Second, the rise of a way of understanding naturalism --materialist or physicalist naturalism-- that wrongly takes naturalism to entail the Denial. (shrink)

This thesis argues for the fundamental importance of the opposition between holistic and reductionistic world-views in economics. Both reductionism and holism may nevertheless underpin laissez-faire policy prescriptions. Scrutiny of the nature of the articulation between micro and macro levels in the writings of economists suggests that invisible hand theories play a key role in reconciling reductionist policy prescriptions with a holistic world. An examination of the prisoners' dilemma in game theory and Arrow's impossibility theorem in social choice theory sets the (...) scene. The prisoners' dilemma epitomises the collective irrationality coordination problems lead to. The source of the dilemma is identified as the combination of interdependence in content and independence in form of the decision making process. Arrovian impossibility has been perceived as challenging traditional views of the relationship between micro and macro levels in economics. Conservative arguments against the possibility in principle of a social welfare function are criticised here as depending on an illicit dualism. The thesis then reviews the standpoints of Smith, Hayek and Keynes. For Smith, the social desirability of individual self-seeking activity is ensured by the 'invisible hand' of a god who has moulded us so to behave, that the quantity of happiness in the world is always maximised. Hayek seeks to re-establish the invisible hand in a secular age, replacing the agency of a deity with an evolutionary mechanism. Hayek's evolutionary theory, criticised here as being based on the exploded notion of group selection, cannot underpin the desirability of spontaneous outcomes. I conclude by arguing that Keynes shares the holistic approach of Smith and Hayek, but without their reliance on invisible hand mechanisms. If spontaneous processes cannot be relied upon to generate desirable social outcomes then we have to take responsibility for achieving this ourselves by establishing the appropriate institutional framework to eliminate macroeconomic prisoners' dilemmas.

In attempts to formulate a computational understanding of brain function, one of the fundamental concerns is the data structure by which the brain represents information. For many decades, a conceptual framework has dominated the thinking of both brain modelers and neurobiologists. That framework is referred to here as "classical neural networks." It is well supported by experimental data, although it may be incomplete. A characterization of this framework will be offered in the next section. Difficulties in modeling important functional aspects (...) of the brain on the basis of classical neural networks alone have led to the recognition that another, general mechanism must be invoked to explain brain function. That mechanism I call " binding." Binding by neural signal synchrony had been mentioned several times in the liter ature before it was fully formulated as a general phenomenon. Although experimental evidence for neural syn chrony was soon found, the idea was largely ignored for many years. Only recently has it become a topic of animated discussion. In what follows, I will summarize the nature and the roots of the idea of binding, especially of temporal binding, and will discuss some of the objec tions raised against it. (shrink)

Recent work on Austrian philosophy has revealed, hitherto, unsuspected links between Vienna circle positivism on the one hand, and the thought of Franz Brentano and his circle on the other. the paper explores these links, casting light also on the Polish analytic movement, on the development of gestalt psychology, and on the work of Schlick and Neurath.

The constructivist perspective has shed new light on the conception of psychopathology and the practice of psychotherapy, surmounting the shortcomings of behaviorism and rationalist cognitive thought, by abandoning the empiricist principle of associationism. In this field, Vittorio Guidano introduced the Cognitive Post -Rationalist model, influenced by attachment theory, evolutionary epistemology, complex systems theory, and the prevalence of abstract mental processes proposed by Hayeck. Guidano conceives the personal system as a self-organized entity, in constant development. The role of the post - (...) rationalist therapist is to strategically upset the system in search of newer and more flexible ways to construct personal experience. (shrink)
