Our folk epistemology says that if someone knows that P and tells you that P, then, given the absence of defeaters, if you believe what they tell you, you will come to know that P as well. A speaker's knowledge that P is then, for the most part, enough for a hearer to come to know that P. But there are counterexamples to this principle: testimonial knowledge does not always transfer from the speaker to the hearer. Why should that be (...) so? Because testimonial knowledge arises through the flow of information--from conclusive grounds--from the speaker through the speaker's assertion to the hearer's state of comprehension as of the speaker's assertion. A speaker's belief can be based on conclusive grounds, but the speaker's assertion may fail to provide conclusive grounds to the hearer. Then the hearer won't acquire knowledge, even from a knowledgeable speaker. Knowledge from testimony then works more like knowledge through perception. But wait, you say, that can't be so because testimony involves free will but perception does not. The essay ends with a broadly Hume inspired reply to this objection. (shrink)

I defend the historical definition of "function" originally given in my Language, Thought and Other Biological Categories (1984a). The definition was not offered in the spirit of conceptual analysis but is more akin to a theoretical definition of "function". A major theme is that nonhistorical analyses of "function" fail to deal adequately with items that are not capable of performing their functions.

In this work the distinguished physical chemist and philosopher, Michael Polanyi, demonstrates that the scientist's personal participation in his knowledge, in both its discovery and its validation, is an indispensable part of science itself. Even in the exact sciences, "knowing" is an art, of which the skill of the knower, guided by his personal commitment and his passionate sense of increasing contact with reality, is a logically necessary part. In the biological and social sciences this becomes even more evident. The (...) tendency to make knowledge impersonal in our culture has split fact from value, science from humanity. Polanyi wishes to substitute for the objective, impersonal ideal of scientific detachment an alternative ideal which gives attention to the personal involvement of the knower in all acts of understanding. His book should help to restore science to its rightful place in an integrated culture, as part of the whole person's continuing endeavor to make sense of the totality of his experience. In honor of this work and his The Study of Man Polanyi was presented with the Lecomte de Noüy Award for 1959. (shrink)

In this 1958 book, Professor Hanson turns to an equally important but comparatively neglected subject, the philosophical aspects of research and discovery.

A scientific community cannot practice its trade without some set of received beliefs. These beliefs form the foundation of the "educational initiation that prepares and licenses the student for professional practice". The nature of the "rigorous and rigid" preparation helps ensure that the received beliefs are firmly fixed in the student's mind. Scientists take great pains to defend the assumption that scientists know what the world is like...To this end, "normal science" will often suppress novelties which undermine its foundations. Research (...) is therefore not about discovering the unknown, but rather "a strenuous and devoted attempt to force nature into the conceptual boxes supplied by professional education". (shrink)

Thomas S. Kuhn's classic book is now available with a new index.

A new class of visuomotor neuron has been recently discovered in the monkey’s premotor cortex: mirror neurons. These neurons respond both when a particular action is performed by the recorded monkey and when the same action, performed by another individual, is observed. Mirror neurons appear to form a cortical system matching observation and execution of goal-related motor actions. Experimental evidence suggests that a similar matching system also exists in humans. What might be the functional role of this matching system? One (...) possible function is to enable an organism to detect certain mental states of observed conspecifics. This function might be part of, or a precursor to, a more general mind-reading ability. Two different accounts of mind-reading have been suggested. According to “theory theory‘, mental states are represented as inferred posits of a naive theory. According to “simulation theory‘, other people’s mental states are represented by adopting their perspective: by tracking or matching their states with resonant states of one’s own. The activity of mirror neurons, and the fact that observers undergo motor facilitation in the same muscular groups as those utilized by target agents, are findings that accord well with simulation theory but would not be predicted by theory theory.

This book outlines a new account of the tacit, meaning tacit knowledge, presuppositions, practices, traditions, and so forth. It includes essays on topics such as underdetermination and mutual understanding, and critical discussions of the major alternative approaches to the tacit, including Bourdieu’s habitus and various practice theories, Oakeshott’s account of tradition, Quentin Skinner’s theory of historical meaning, Harry Collins’s idea of collective tacit knowledge, as well as discussions of relevant cognitive science concepts, such as non-conceptual content, connectionism, and mirror neurons. (...) The new account of tacit knowledge focuses on the fact that in making the tacit explicit, a person is not, as many past accounts have supposed, reading off the content of some sort of shared and fixed tacit scheme of presuppositions, but rather responding to the needs of the Other for understanding.

In this volume, Maher contextualizes the work of a group of contemporary analytic philosophers—The Pittsburgh School—whose work is characterized by an interest in the history of philosophy and a commitment to normative functionalism, or the insight that to identify something as a manifestation of conceptual capacities is to place it in a space of norms. Wilfrid Sellars claimed that humans are distinctive because they occupy a norm-governed "space of reasons." Along with Sellars, Robert Brandom and John McDowell have tried to (...) work out the implications of that idea for understanding knowledge, thought, norms, language, and intentional action. The aim of this book is to introduce their shared views on those topics, while also charting a few key disputes between them. (shrink)

This is a review of Ruth Garrett Millikan's 1993 book, White Queen Psychology and Other Essays for Alice.

This paper proposes a basic revision of the understanding of teleology in biological sciences. Since Kant, it has become customary to view purposiveness in organisms as a bias added by the observer; the recent notion of teleonomy expresses well this as-if character of natural purposes. In recent developments in science, however, notions such as self-organization (or complex systems) and the autopoiesis viewpoint, have displaced emergence and circular self-production as central features of life. Contrary to an often superficial reading, Kant gives (...) a multi-faceted account of the living, and anticipates this modern reading of the organism, even introducing the term self-organization for the first time. Our re-reading of Kant in this light is strengthened by a group of philosophers of biology, with Hans Jonas as the central figure, who put back on center stage an organism-centered view of the living, an autonomous center of concern capable of providing an interior perspective. Thus, what is present in nuce in Kant, finds a convergent development from this current of philosophy of biology and the scientific ideas around autopoeisis, two independent but parallel developments culminating in the 1970s. Instead of viewing meaning or value as artifacts or illusions, both agree on a new understanding of a form of immanent teleology as truly biological features, inevitably intertwined with the self-establishment of an identity which is the living process.

A great deal of philosophy of mind in the modern era has been driven by an intense aversion to Cartesian dualism. In the 1950s, materialists claimed to have succeeded once and for all in exorcising the Cartesian ghost by identifying the mind with the brain. In subsequent decades, cognitive science put scientific meat on this metaphysical skeleton by explicating mental processes as digital computation implemented in the brain's hardware.

ArgumentThis paper builds on a neglected philosophical idea,Evidenz. Max Weber used it in his discussion ofVerstehen, as the goal of understanding either action or such things as logic. It was formulated differently by Franz Brentano, but with a novel twist: thatanyonewho understood something would see the thing to be understood as self-evident, not something dependent on inference, argument, or reasoning. The only way one could take something as evident in this sense is by being able to treat other people as (...) having the same responses – by empathy with them, in the weak sense of following their thought. Brentano's philosophical claim is that without some stopping point at what is self-evident, justifications fall into infinite regress. This is radically opposed to much of conventional philosophy. The usual solutions to the regress problem rely on problematic claims about the supposed hidden transcendental structure behind reasoning. In contrast, empathy is a genuine natural phenomenon and a better explanation for the actual phenomenon of making sense of the reasoning of others. What is evident to all who are capable of understanding is an empirically-defined subset of this class. (shrink)

In The Construction of Social Reality, John Searle expends an argument left undeveloped in Speech Acts about the nature of the rules which underlie and constitute social life. It is argued in this review that one problem for this account was its apparent incompatibility with connectionism. They cannot be rules shared in the head, so to speak. He now understands our relation to these rules not as one of simple internalization but of skillful accustoming. But this makes appeal to rules (...) unnecessary and makes noncollective solutions appealing to overt beliefs rather than tacit rules more plausible. (shrink)

The concept of "practices"—whether of representation, of political or scientific traditions, or of organizational culture—is central to social theory. In this book, Stephen Turner presents the first analysis and critique of the idea of practice as it has developed in the various theoretical traditions of the social sciences and the humanities. Understood broadly as a tacit understanding "shared" by a group, the concept of a practice has a fatal difficulty, Turner argues: there is no plausible mechanism by which a "practice" (...) is transmitted or reproduced. The historical uses of the concept, from Durkheim to Kripke's version of Wittgenstein, provide examples of the contortions that thinkers have been forced into by this problem, and show the ultimate implausibility of the idea. Turner's conclusion sketches a picture of what happens when we do without the notion of a shared practice, and how this bears on social theory and philosophy. It explains why social theory cannot get beyond the stage of constructing fuzzy analogies, and why the standard constructions of the contemporary philosophical problem of relativism depend upon this defective notion. This first book-length critique of practice theory is sure to stir discussion and controversy in a wide range of fields, from philosophy and science studies to sociology, anthropology, literary studies, and political and legal theory.

Tacit knowledge is both a ubiquitous and puzzling notion, related to the idea of hidden assumptions. The puzzle is partly a result of the conflict between the idea that assumptions are in the mind and the apparent audience-relativity of the "fact" of possessing an assumption or of the tacit knowledge that is articulated. If we think of making the tacit explicit as constructing a certain kind of inference repairing explanation for a particular audience "on the fly" we come closer to (...) an explanation of what happens when we "make our tacit knowledge explicit." We can account for our capacity to construct such statements for particular audiences by reference to our non-conceptual capacities to understand others. This approach avoids problematic assumptions about shared representations that are common in cognitive science, and the equally problematic notion that tacit knowledge is sentence-like content that we retrieve when we articulate something based on our tacit knowledge.

In the decade and a half since the appearance of Varela, Thompson and Rosch's workThe Embodied Mind,enactivism has helped to put experience and consciousness, conceived of in a distinctive way, at the forefront of cognitive science. There are at least two major strands within the enactive perspective: a broad view of what it is to be an agent with a mind; and a more focused account of the nature of perception and perceptual experience. The relation between these two strands is (...) discussed, with an overview of the papers presented in this volume. (shrink)

This paper explores some of the differences between the enactive approach in cognitive science and the extended mind thesis. We review the key enactive concepts of autonomy and sense-making . We then focus on the following issues: (1) the debate between internalism and externalism about cognitive processes; (2) the relation between cognition and emotion; (3) the status of the body; and (4) the difference between ‘incorporation’ and mere ‘extension’ in the body-mind-environment relation.

On the extended mind hypothesis (EM), many of our cognitive states and processes are hybrids, unevenly distributed across biological and nonbiological realms. In certain circumstances, things - artifacts, media, or technologies - can have a cognitive life, with histories often as idiosyncratic as those of the embodied brains with which they couple. The realm of the mental can spread across the physical, social, and cultural environments as well as bodies and brains. My independent aims in this chapter are: first, to (...) describe two compatible but distinct movements or "waves" within the EM literature, arguing for the priority of the second wave (and gesturing briefly toward a third); and, second, to defend and illustrate the interdisciplinary implications of EM as best understood, specifically for historical disciplines, by sketching two case studies.

The term “social cognition” can be construed in different ways. On the one hand, it can refer to the cognitive faculties involved in social activities, defined simply as situations where two or more individuals interact. On this view, social systems would consist of interactions between autonomous individuals; these interactions form higher-level autonomous domains not reducible to individual actions. A contrasting, alternative view is based on a much stronger theoretical definition of a truly social domain, which is always defined by a (...) set of structural norms; moreover, these social structures are not only a set of constraints, but actually constitute the possibility of enacting worlds that would just not exist without them. This view emphasises the heteronomy of individuals who abide by norms that are impersonal, culturally inherited and to a large extent independent of the individuals. Human beings are socialised through and through; consequently, all human cognition is social cognition. The article argues for this second position. Finally, it appears that fully blown autonomy actually requires heteronomy. It is the acceptance of the constraints of social structures that enables individuals to enter new realms of common meaningfulness. The emergence of social life marks a crucial step in the evolution of cognition; so that at some evolutionary point human cognition cannot but be social cognition. (shrink)

Andy Clark and David Chalmers claim that cognitive processes can and do extend outside the head.1 Call this the “hypothesis of extended cognition” (HEC). HEC has been strongly criticised by Fred Adams, Ken Aizawa and Robert Rupert.2 In this paper I argue for two claims. First, HEC is a harder target than Rupert, Adams and Aizawa have supposed. A widely-held view about the nature of the mind, functionalism—a view to which Rupert, Adams and Aizawa appear to subscribe— entails HEC. Either (...) HEC is true, or functionalism is false. The relationship between functionalism and HEC goes beyond support for the relatively uncontroversial claim that it is logically or nomologically possible for cognition to extend (the “can” part of HEC); functionalism entails that cognitive processes do extend in the actual world. Second, I argue that the version of HEC entailed by functionalism is more radical than the version that Clark and Chalmers suggest. I argue that it is so radical as to form a counterexample to functionalism. If functionalism is modified to prevent these consequences, then HEC falls victim to Rupert, Adams and Aizawa’s original criticism. An advocate of HEC has two choices: (1) accept functionalism and radical HEC; (2) give up HEC entirely. Clark and Chalmers’ intermediate position of a modest form of HEC is unsustainable. The argument of this paper, although initially appearing to support Clark and Chalmers, ultimately argues against their position. The price of HEC is rampant expansion of the mind into the world, and the implausibility of such expansion is indicative of deep-seated problems with functionalism. The argument of this paper consequently speaks to wider issues than just the status of HEC. The reasons for.. (shrink)

Dreyfus's model of expert skill acquisition is philosophically important because it shifts the focus on expertise away from its social and technical externalization in STS, and its relegation to the historical and psychological context of discovery in the classical philosophy of science, to universal structures of embodied cognition and affect. In doing so he explains why experts are not best described as ideologues and why their authority is not exclusively based on social networking. Moreover, by phenomenologically analyzing expertise from a (...) first person perspective, he reveals the limitations of, and sometimes superficial treatment that comes from, investigating expertise from a third person perspective. Thus, he shows that expertise is a prime example of a subject that is essential to science but can only be fully elaborated with the aid of phenomenological tools. However, both Dreyfus's descriptive model and his normative claims are flawed due to the lack of hermeneutical sensitivity. He assumes an expert's knowledge has crystallized out of contextual sensitivity plus experience, and that an expert has shed, during the training process, whatever prejudices, ideologies, hidden agendas, or other forms of cultural embeddedness, that person might have begun with. One would never imagine, from Dreyfus's account, that society could possibly be endangered by experts, only how society's expectations and actions could endanger experts. The stories of actual controversies not only shows things do not work the way Dreyfus claims, but also that it would be less salutary if they did. Such stories amount to counterexamples to Dreyfus's normative claims, and point to serious shortcomings in his arguments. (shrink)

A proposal for the biological grounding of intrinsic teleology and sense-making through the theory of autopoiesis is critically evaluated. Autopoiesis provides a systemic lan- guage for speaking about intrinsic teleology but its original formulation needs to be elaborated further in order to explain sense-making. This is done by introducing adaptivity, a many-layered property that allows organisms to regulate themselves with respect to their conditions of via- bility. Adaptivity leads to more articulated concepts of behaviour, agency, sense-construction, health, and temporality than (...) those given so far by autopoiesis and enaction. These and other implications for understanding the organismic generation of values are explored. (shrink)

Many current neurophysiological, psychophysical, and psychological approaches to vision rest on the idea that when we see, the brain produces an internal representation of the world. The activation of this internal representation is assumed to give rise to the experience of seeing. The problem with this kind of approach is that it leaves unexplained how the existence of such a detailed internal representation might produce visual consciousness. An alternative proposal is made here. We propose that seeing is a way of (...) acting. It is a particular way of exploring the environment. Activity in internal representations does not generate the experience of seeing. The out- side world serves as its own, external, representation. The experience of seeing occurs when the organism masters what we call the gov- erning laws of sensorimotor contingency. The advantage of this approach is that it provides a natural and principled way of accounting for visual consciousness, and for the differences in the perceived quality of sensory experience in the different sensory modalities. Sev- eral lines of empirical evidence are brought forward in support of the theory, in particular: evidence from experiments in sensorimotor adaptation, visual “filling in,” visual stability despite eye movements, change blindness, sensory substitution, and color perception.

This collection of essays serves both as an introduction to Ruth Millikan’s much-discussed volume Language, Thought, and Other Biological Categories and as an extension and application of Millikan’s central themes, especially in the philosophy of psychology. The title essay discusses meaning rationalism and argues that rationality is not in the head, indeed, that there is no legitimate interpretation under which logical possibility and necessity are known a priori. In other essays, Millikan clarifies her views on the nature of mental representation, (...) explores whether human thought is a product of natural selection, examines the nature of behavior as studied by the behavioral sciences, and discusses the issues of individualism in psychology, psychological explanation, indexicality in thought, what knowledge is, and the realism/antirealism debate.

A list of groceries, Professor Anscombe once suggested, might be used as a shopping list, telling what to buy, or it might be used as an inventory list, telling what has been bought (Anscombe 1957). If used as a shopping list, the world is supposed to conform to the representation: if the list does not match what is in the grocery bag, it is what is in the bag that is at fault. But if used as an inventory list, the (...) representation is supposed to conform to the world: if the list does not match what is in the bag, it is the list that is at fault. The first kind of representation, where the world is supposed to conform to the list, can be called "directive"; it represents or directs what is to be done. The second, where the list is supposed to conform to the world, can be called "descriptive"; it represents or describes what is the case. I wish to propose that there exist representations that face both these ways at once. With apologies to Dr. Doolittle, I call them pushmi-pullyu representations or PPRs. (shrink)

I propose to bring fresh evidence here for my theory of knowledge and expand it in new directions. We shall arrive most swiftly at the centre of the theory, by going back to the point from which I started about twenty years ago. Upon examining the grounds on which science is pursued, I saw that its progress is determined at every stage by indefinable powers of thought. No rules can account for the way a good idea is found for starting (...) an inquiry; and there are no firm rules either for the verification or the refutation of the proposed solution of a problem. Rules widely current may be plausible enough, but scientific enquiry often proceeds and triumphs by contradicting them. Moreover, the explicit content of a theory fails to account for the guidance it affords to future discoveries. To hold a natural law to be true, is to believe that its presence may reveal itself in yet unknown and perhaps yet unthinkable consequences; it is to believe that such laws are features of a reality which as such will continue to bear consequences inexhaustibly.

Naturalistic philosophers ought to think that the mind is continuous with the rest of the world and should not, therefore, be surprised by the findings of the extended mind, cognitive integration and enactivism. Not everyone is convinced that all mental phenomena are continuous with the rest of the world. For example, intentionality is often formulated in a way that makes the mind discontinuous with the rest of the world. This is a consequence of Brentano’s formulation of intentionality, I suggest, and (...) can be overcome by revealing that the concept of intentional directedness as he receives it from the Scholastics is quite consistent with the continuity thesis. It is only when intentional directedness is conjoined with intentional inexistence that intentionality and content are consistent with a discontinuity thesis (such as Brentano’s thesis). This makes room to develop an account of intentional directedness that is consistent with the continuity thesis in the form of Peirce’s representational principle. I also argue against a form of the discontinuity thesis in the guise of the derived/underived content distinction. Having shown that intentionality is consistent with the continuity thesis I argue that we should focus on intentionality and representation as bodily enacted. I conclude that we would be better off focussing on representation and intentionality in action rather than giving abstract functional accounts of extended cognition. (shrink)
