This book introduces an account of cognitive architecture, Cognitive Pluralism, on which the basic units of understanding are models of particular content domains. Having many mental models is a good adaptive strategy for cognition, but models can be incompatible with one another, leading to paradoxes and inconsistencies of belief, and it may not be possible to integrate the understanding supplied by multiple models into a comprehensive and self-consistent "super model". The book applies the theory to explaining intuitive reasoning and cognitive (...) illusions and explores implications for epistemology, semantics, and disunity of science. (shrink)

This essay describes an approach to designing a course in philosophy as a way of life (PWOL) around a set of immersive “spiritual exercises” through which students might examine their desires, engaging students in a process of testing their own experience against philosophical theories and theories against their own experience. These are used to tie together the units of a course covering classical Western and Eastern philosophical traditions, and to supplement traditional philosophical analysis of texts and arguments with ways of (...) exploring what it might be like to live as a Platonist, Stoic, or Confucian. The essay details several exercises, engages perspectives on PWOL from Pierre Hadot and John Cooper, and addresses the question of how to assess immersive exercises. (shrink)

Contemporary philosophers of mind tend to assume that the world of nature can be reduced to basic physics. Yet there are features of the mind consciousness, intentionality, normativity that do not seem to be reducible to physics or neuroscience. This explanatory gap between mind and brain has thus been a major cause of concern in recent philosophy of mind. Reductionists hold that, despite all appearances, the mind can be reduced to the brain. Eliminativists hold that it cannot, and that this (...) implies that there is something illegitimate about the mentalistic vocabulary. Dualists hold that the mental is irreducible, and that this implies either a substance or a property dualism. Mysterian non-reductive physicalists hold that the mind is uniquely irreducible, perhaps due to some limitation of our self-understanding. In this book, Steven Horst argues that this whole conversation is based on assumptions left over from an outdated philosophy of science. While reductionism was part of the philosophical orthodoxy fifty years ago, it has been decisively rejected by philosophers of science over the past thirty years, and for good reason. True reductions are in fact exceedingly rare in the sciences, and the conviction that they were there to be found was an artifact of armchair assumptions of 17th century Rationalists and 20th century Logical Empiricists. The explanatory gaps between mind and brain are far from unique. In fact, in the sciences it is gaps all the way down.And if reductions are rare in even the physical sciences, there is little reason to expect them in the case of psychology. Horst argues that this calls for a complete re-thinking of the contemporary problematic in philosophy of mind. Reductionism, dualism, eliminativism and non-reductive materialism are each severely compromised by post-reductionist philosophy of science, and philosophy of mind is in need of a new paradigm. Horst suggests that such a paradigm might be found in Cognitive Pluralism: the view that human cognitive architecture constrains us to understand the world through a plurality of partial, idealized, and pragmatically-constrained models, each employing a particular representational system optimized for its own problem domain. Such an architecture can explain the disunities of knowledge, and is plausible on evolutionary grounds. (shrink)

In this carefully argued critique, Steven Horst pronounces the theory deficient.

Since the seventeenth century, our understanding of the natural world has been one of phenomena that behave in accordance with natural laws. While other elements of the early modern scientific worldview may be rejected or at least held in question—the metaphor of the world as a great machine, the narrowly mechanist assumption that all physical interactions must be contact interactions, the idea that matter might actually be obeying rules laid down by its Divine Author – the notion of natural law (...) has continued to play a pivotal role in actual scientific practice, in our philosophical interpretations of science, and in their its metaphysical implications.

Over the past thirty years, it is been common to hear the mind likened to a digital computer. This essay is concerned with a particular philosophical view that holds that the mind literally is a digital computer (in a specific sense of “computer” to be developed), and that thought literally is a kind of computation. This view—which will be called the “Computational Theory of Mind” (CTM)—is thus to be distinguished from other and broader attempts to connect the mind with computation, (...) including (a) various enterprises at modeling features of the mind using computational modeling techniques, and (b) employing some feature or features of production-model computers (such as the stored program concept, or the distinction between hardware and software) merely as a guiding metaphor for understanding some feature of the mind. This entry is therefore concerned solely with the Computational Theory of Mind (CTM) proposed by Hilary Putnam [1961] and developed most notably for philosophers by Jerry Fodor [1975, 1980, 1987, 1993]. The senses of ‘computer’ and ‘computation’ employed here are technical; the main tasks of this entry will therefore be to elucidate: (a) the technical sense of ‘computation’ that is at issue, (b) the ways in which it is claimed to be applicable to the mind, (c) the philosophical problems this understanding of the mind is claimed to solve, and (d) the major criticisms that have accrued to this view.

Most contemporary philosophers of mind claim to be in search of a 'naturalistic' theory. However, when we look more closely, we find that there are a number of different and even conflicting ideas of what would count as a 'naturalization' of the mind. This article attempts to show what various naturalistic philosophies of mind have in common, and also how they differ from one another. Additionally, it explores the differences between naturalistic philosophies of mind and naturalisms found in ethics, epistemology, (...) and philosophy of science. Section 1 introduces a distinction between two types of project that have been styled 'naturalistic', which I call philosophical naturalism and empirical naturalism . Sections 2 to 6 canvass different strands of philosophical naturalism concerning the mind, followed by a much briefer discussion of attempts to provide empirical naturalizations of the mind in Section 7 . Section 8 concludes the essay with a consideration of the relations between philosophical and empirical naturalism in philosophy of mind, arguing that at least some types of philosophical naturalism are incompatible with empirical naturalism.

Recent philosophy of mind has tended to treat.

Chalmers and others have argued that physicalist microexplanation is incapable of solving the ‘hard problem’ of consciousness. This article examines whether evolutionary accounts of the mind, such as those developed by Millikan, Dretske and Flanagan, can add anything to make up for the possible short falls of more reductionist accounts. I argue that they cannot, because evolutionary accounts explain by appeal to a selectional history that only comes into the picture if consciousness can first arise due to spontaneous mutation in (...) some individual organism, and explaining this emergence of consciousness from DNA and embryology calls for precisely the kind of structurally-based supervenience account that Chalmers et al. have objected to. Not only does an evolutionary account not succeed where a reductionist account fails; the evolutionary account presupposes the possibility of a reductionist account. (shrink)

Over the past several decades, the philosophical community has witnessed the emergence of an important new paradigm for understanding the mind.1 The paradigm is that of machine computation, and its influence has been felt not only in philosophy, but also in all of the empirical disciplines devoted to the study of cognition. Of the several strategies for applying the resources provided by computer and cognitive science to the philosophy of mind, the one that has gained the most attention from philosophers (...) has been the Computational Theory of Mind (CTM). CTM was first articulated by Hilary Putnam (1960, 1961), but finds perhaps its most consistent and enduring advocate in Jerry Fodor (1975, 1980, 1981, 1987, 1990, 1994). It is this theory, and not any broader interpretations of what it would be for the mind to be a computer, that I wish to address in this paper. What I shall argue here is that the notion of symbolic representation employed by CTM is fundamentally unsuited to providing an explanation of the intentionality of mental states (a major goal of CTM), and that this result undercuts a second major goal of CTM, sometimes refered to as the vindication of intentional psychology. This line of argument is related to the discussions of derived intentionality by Searle (1980, 1983, 1984) and Sayre (1986, 1987). But whereas those discussions seem to be concerned with the causal dependence of familiar sorts of symbolic representation upon meaning-bestowing acts, my claim is rather that there is not one but several notions of meaning to be had, and that the notions that are applicable to symbols are conceptually dependent upon the notion that is applicable to mental states in the fashion that Aristotle refered to as paronymy. That is, an analysis of the notions of meaning applicable to symbols reveals that they contain presuppositions about meaningful mental states, much as Aristotle's analysis of the sense of healthy that is applied to foods reveals that it means conducive to having a healthy body, and hence any attempt to explain mental semantics in terms of the semantics of symbols is doomed to circularity and regress. I shall argue, however, that this does not have the consequence that computationalism is bankrupt as a paradigm for cognitive science, as it is possible to reconstruct CTM in a fashion that avoids these difficulties and makes it a viable research framework for psychology, albeit at the cost of losing its claims to explain intentionality and to vindicate intentional psychology. I have argued elsewhere (Horst, 1996) that local special sciences such as psychology do not require vindication in the form of demonstrating their reducibility to more fundamental theories, and hence failure to make good on these philosophical promises need not compromise the broad range of work in empirical cognitive science motivated by the computer paradigm in ways that do not depend on these problematic treatments of symbols.

This article examines the notions of “intuitive” and “counterintuitive” beliefs and concepts in cognitive science of religion. “Intuitive” states are contrasted with those that are products of explicit, conscious reasoning. In many cases the intuitions are grounded in the implicit rules of mental models, frames, or schemas. I argue that the pathway from intuitive to high theological concepts and beliefs may be distinct from that from intuitions to “folk religion,” and discuss how Christian theology might best interpret the results of (...) studies in cognitive psychology of religion.

Recent debates about the metaphysics of mind have tended to assume that inter-theoretic reductions are the norm in the natural sciences. With this assumption in place, the apparent explanatory gaps surrounding consciousness and intentionality seem unique, fascinating, and perhaps metaphysically significant. Over the past several decades, however, philosophers of science have largely rejected the notions that inter-theoretic reduction is either widespread in the natural sciences or a litmus for the legitimacy of the special sciences. If we adopt a post-reductionist philosophy (...) of science, with a commitment to theory pluralism, the epistemic statuses of the standard positions in philosophy of mind (reductionism, non-reductive physicalism, dualism) are all significantly changed. Moreover, central problems of recent philosophy of mind – reducibility and the explanatory gap – seem themselves to be in need of rethinking if reductions are rare and the sciences have “explanatory gaps all the way down.” This article examines the prospects of the standard metaphysical positions, plus two types of pluralism, in light of post-reductionist philosophy of science.

It has recently been claimed (1) that mental states such as beliefs are theoretical entities and (2) that they are therefore, in principle, subject to theoretical elimination if intentional psychology were to be supplanted by a psychology not employing mentalistic notions. Debate over these two issues is seriously hampered by the fact that the key terms 'theoretical' and 'belief' are ambiguous. This article argues that there is only one sense of 'theoretical' that is of use to the eliminativist, and in (...) this sense some kinds of "belief" (dispositional states, infra-conscious states and the Freudian unconscious) are indeed "theoretical" and hence possible candidates for elimination, while others (consciously occurring thoughts like judgements and perceptual Gestalten) are not theoretical and hence not candidates for elimination.

Since early modernity, it has often been assumed that miracles are incompatible with the existence of the natural laws utilized in the sciences. This paper argues that this assumption is largely an artifact of empiricist accounts of laws that should be rejected for reasons internal to philosophy of science, and that no such incompatibility arises on the most important alternative interpretations, which treat laws as expressions of forces, dispositions, or causal powers.

This paper presents the lineaments of a new account of concepts. The foundations of the account are four ideas taken from recent cognitive science, though most of them have important philosophical precursors. The first is the idea that human conceptuality shares important continuities with psychological faculties of other animals, and indeed that there is a well-distinguished hierarchy of such faculties that extend up and down the phylogenetic scale. While it would very likely be a mistake to look at some conglomeration (...) of these simpler abilities and assert that we have produced a reductive account of human conceptuality, an examination of these will lend insights into essential features of human conceptuality in a non-reductive, non-exhaustive manner. The second idea is that an important function of both human concepts and of their protoconceptual ancestors in the animal kingdom is to make distinctions or discriminations. We shall thus look at the human conceptual apparatus as being, in large part, a discrimination engine. How are these discriminations realized in humans and other beings? Presumably, some discriminative mechanisms are innate, while others are acquired through learning. But how is learning accomplished? The third idea from cognitive science is that adaptive discrimination is realized through neural networks, and that the properties of this realizing system explains familiar features of human thought that seem puzzling when viewed through other lenses, such as the logical analysis of language. The fourth and. (shrink)

This is a relatively breezy version of an exploration of some issues about how to provide a theory of concepts and conceptual semantics. I have also written more conventional versions of some of this material (without the Three Bears motif), though those are set in a broader context.

The SPP is, among other things, a place where we discuss nagging and perennial problems on the bordermarches between philosophy and the sciences. Sometimes problems are nagging and perennial because they are deep and difficult. And sometimes they are merely an artifact, a shadow cast by our own way of formulating the problem. I should like to suggest to you that philosophy of mind suffers badly from being the last refuge of the best philosophy of science of the 1950's, and (...) that some of its problems are in fact illusions that could be dispelled by consideration of more recent developments in the philosophy of science. In particular, philosophy of psychology has been plagued by a famous contrast between its "ceteris paribus" laws and the "exceptionless" laws of the physical sciences. This has led to doubts about the scientific status of psychology, the status of psychological kinds as natural kinds, and even their ontological legitimacy. I argue here that this problematic is a consequence of assuming a particular analysis of scientific laws as (exceptionless) universally quantifed claims. This analysis has largely been rejected in contemporary philosophy of science. And more recent analyses that take notice of the role of idealization in scientific modeling both dissolve the nagging problem and shed new light upon differences between the sciences. (shrink)

The New Semantics (NS) introduced by Kripke and Putnam is often thought to block antiphysicalist arguments that involve an inference from an explanatory gap to a failure of supervenience. But this “NS Rebuttal” depends upon two assumptions that are shown to be dubious. First, it assumes that mental-kind terms are among the kinds of terms to which NS analysis is properly applied. However, there are important differences in this regard between the behavior of notions like ‘pain’ and notions like ‘water’, (...) as Kripke himself has argued. Second, even on the assumption that NS analysis is appropriate to mental-kind terms, it is further assumed that this would block the anti-physicalist premise that an abiding and principled explanatory gap would entail a failure of metaphysical supervenience. But the paradigm examples of NS analysis show nothing of the sort. What they show is that there are a posteriori necessities (e.g., “water contains hydrogen”) that cannot be inferred from the sense of natural kind terms. But they do not show that such necessities cannot be derived from an adequate scientific understanding of the phenomena in question. Indeed, such derivations are often available with kinds like water, but seem unavailable with mental kinds like ‘pain’ and ‘belief’. (shrink)

This response to Silberstein's review undertakes two tasks. First, it attempts to clarify aspects of Cognitive Pluralism and its relationship to anti-reductionism. Second, it engages Silberstein's claim that traditional metaphysics of mind is dead, or at least should no longer be pursued.

This book offers a sustained critique of the computational theory of mind that deserves the attention of those interested in the presuppositions and implications of computational psychology. Horst begins by laying out the theory, reconstructing its perceived role in vindicating intentional psychology, and recounting earlier critiques on which he builds. Part 2, the heart of the book, analyzes a notion central to CTM—that of a symbol—arguing that symbols are conventional. In Part 3 Horst applies the results of this (...) analysis to CTM to diagnose a serious confusion in its account of semantic properties and the corresponding notion of mental representation. Part 4 offers an alternative perspective on computational psychology, suggesting a separation of the practice of computational psychology from the philosophical claims made by CTM. (shrink)

Laws, Mind, and Free Will is a highly valuable book for anyone interested in philosophy of science, philosophy of mind, or in the problem of free will and moral responsibility. The book has three distinct but related parts. The first presents an anti-empiricist position on the laws of nature, according to which the point of the laws is not primarily to predict kinematic outcomes, but rather to characterize dynamics. One upshot of the account is that the laws have an attenuated (...) role in determining and prediction of actual motion, and this has an important consequence for the relevance of the laws to the prospects for libertarian free will. This consequence is developed in detail in the second part of the book. A further feature of the account is that proposed laws and the theories in which they are embedded are models in a sense that reflects our interests and involves idealization. In Horst’s view, this is true for theories and laws across the sciences—from physics to psychology. The l .. (shrink)

Steven Crowell has been for many years a leading voice in debates on twentieth-century European philosophy. This volume presents thirteen recent essays that together provide a systematic account of the relation between meaningful experience and responsiveness to norms. They argue for a new understanding of the philosophical importance of phenomenology, taking the work of Husserl and Heidegger as exemplary, and introducing a conception of phenomenology broad enough to encompass the practices of both philosophers. Crowell discusses Husserl's analyses of first-person (...) authority, the semantics of conscious experience, the structure of perceptual content, and the embodied subject, and shows how Heidegger's interpretation of the self addresses problems in Husserl's approach to the normative structure of meaning. His volume will be valuable for upper-level students and scholars interested in phenomenological approaches to philosophical questions in both the European and the analytic traditions. (shrink)

Baruch Spinoza (1632-1677) was one of the most important philosophers of all time; he was also one of the most radical and controversial. The story of Spinoza's life takes the reader into the heart of Jewish Amsterdam in the seventeenth century and, with Spinoza's exile from Judaism, into the midst of the tumultuous political, social, intellectual, and religious world of the young Dutch Republic. This new edition of Steven Nadler's biography, winner of the Koret Jewish Book Award for biography (...) and translated into a dozen languages, is enhanced by exciting new archival discoveries about his family background, his youth, and the various philosophical, political, and religious contexts of his life and works. There is more detail about his family's business and communal activities, about his relationships with friends and correspondents, and about the development of his writings, which were so scandalous to his contemporaries.

This chapter proposed a novel design methodology called Value-Sensitive Design and its potential application to the field of artificial intelligence research and design. It discusses the imperatives in adopting a design philosophy that embeds values into the design of artificial agents at the early stages of AI development. Because of the high risk stakes in the unmitigated design of artificial agents, this chapter proposes that even though VSD may turn out to be a less-than-optimal design methodology, it currently provides a (...) framework that has the potential to embed stakeholder values and incorporate current design methods. The reader should begin to take away the importance of a proactive design approach to intelligent agents. (shrink)

From Pulitzer Prize-finalist Steven Nadler, an engaging guide to what Spinoza can teach us about life’s big questions In 1656, after being excommunicated from Amsterdam’s Portuguese-Jewish community for “abominable heresies” and “monstrous deeds,” the young Baruch Spinoza abandoned his family’s import business to dedicate his life to philosophy. He quickly became notorious across Europe for his views on God, the Bible, and miracles, as well as for his uncompromising defense of free thought. Yet the radicalism of Spinoza’s views has (...) long obscured that his primary reason for turning to philosophy was to answer one of humanity’s most urgent questions: How can we lead a good life and enjoy happiness in a world without a providential God? In Think Least of Death, Pulitzer Prize–finalist Steven Nadler connects Spinoza’s ideas with his life and times to offer a compelling account of how the philosopher can provide a guide to living one’s best life. In the Ethics, Spinoza presents his vision of the ideal human being, the “free person” who, motivated by reason, lives a life of joy devoted to what is most important—improving oneself and others. Untroubled by passions such as hate, greed, and envy, free people treat others with benevolence, justice, and charity. Focusing on the rewards of goodness, they enjoy the pleasures of this world, but in moderation. “The free person thinks least of all of death,” Spinoza writes, “and his wisdom is a meditation not on death but on life." An unmatched introduction to Spinoza’s moral philosophy, Think Least of Death shows how his ideas still provide valuable insights about how to live today. (shrink)

While there are many competing accounts and scales of intellectual humility, philosophers and psychologists are generally united in treating it as an epistemically _beneficial_ disposition of _individual_ agents. I call the research guided by this supposition the _traditional approach_ to studying intellectual humility. The traditional approach is entirely understandable in light of recent findings that individual differences in intellectual humility are associated with various deleterious epistemic tendencies. Nonetheless, I argue that its near monopoly has resulted in an underestimation of important (...) limitations of human cognition. In particular, it neglects the fact that intellectual arrogance can be both deeply recalcitrant and significantly beneficial for bounded cognitive agents whose reliance on one another is profound. I propose to integrate these insights into the study of intellectual humility by treating it as a _collective virtue_ that gets manifested in the structure of epistemic environments. More specifically, it is an interactive virtue that harnesses and constrains intellectual arrogance to yield benefits for both individuals and collectives. I claim that this can happen only within _humbling environments_, such as forecasting tournaments and open institutional science. (shrink)
