The amygdala is a key brain area regulating responses to stress and emotional stimuli, so improving our understanding of how it is regulated could offer novel strategies for treating disturbances in emotion regulation. As we review here, a growing body of evidence indicates that the gut microbiota may contribute to a range of amygdala-dependent brain functions from pain sensitivity to social behavior, emotion regulation, and therefore, psychiatric health. In addition, it appears that the microbiota is necessary for normal development of (...) the amygdala at both the structural and functional levels. While further investigations are needed to elucidate the exact mechanisms of microbiota-to-amygdala communication, ultimately, this work raises the intriguing possibility that the gut microbiota may become a viable treatment target in disorders associated with amygdala dysregulation, including visceral pain, post-traumatic stress disorder, and beyond. Also see the video abstract here: https://youtu.be/O5gvxVJjX18 The amygdala plays a central role in regulating many aspects of behavior in rodents and humans, from pain responding to social interaction and psychiatric function. Accumulating evidence suggests microbiota-to-amygdala communication along the gut-brain axis is a key modulator of these amygdala-dependent behaviors, with critical implications for health and disease.

This commentry focuses on the one major ecumenical theme propounded in Andy Clark's Being There that I find difficult to accept; this is Clark’s advocacy, especially in the third and final part of the book, of the extended nature of the embedded, embodied mind.

This essay, by the editor of Common Knowledge, introduces the sixth and final installment of “Fuzzy Studies,” the journal's “Symposium on the Consequence of Blur.” Suggesting that “Fuzzy Studies” should be understood in the context of a desultory campaign against zeal conducted in the journal for almost twenty years, he explains that the editors' assumption has been that any authentic case for the less adamant modes of thinking, or the less focused ways of seeing, needs to be unenthusiastic and carefully (...) ramified. To establish the distinction between overenthused and unemphatic approaches to blur, he contrasts the ecstatically amorphous “Blur building” with examples of classical Chinese landscape painting. Elizabeth Diller and Richard Scofidio, in their book blur: the making of nothing, chronicle the development of their plans for the Blur building and, in the process, inadvertently show that, to overbear various negative associations of blur and fog, the authors/architects grew self-contradictorily emphatic about the need to produce de-emphasis in architecture and in modern life. Perl shows how this self-contradiction appears also in phenomenology-inflected writings on blur by T. J. Clark, Yve-Alain Bois and Rosalind Kraus, J.-P. Sartre, and Georges Bataille, but not in the work of the phenomenologist François Jullien, whose book The Great Image Has No Form analyzes the role of blur in classical Chinese art theory and practice. Where traditional Western painting, Jullien argues, calls for voyeuristically intense focus, traditional Chinese painting stimulates “dé-tente, relaxation or ‘untensing’.” Intense focus on a blur is still, Perl observes, an intense focus. In describing a painting by the Yuan Dynasty master Ni Zan, Perl concludes that the only way to be un-self-contradictorily positive about fuzziness, whether in logic or aesthetics, is to de-reify and de-differentiate with the aim of achieving blandness.

Brains, it has recently been argued, are essentially prediction machines. They are bundles of cells that support perception and action by constantly attempting to match incoming sensory inputs with top-down expectations or predictions. This is achieved using a hierarchical generative model that aims to minimize prediction error within a bidirectional cascade of cortical processing. Such accounts offer a unifying model of perception and action, illuminate the functional role of attention, and may neatly capture the special contribution of cortical processing to (...) adaptive success. This target article critically examines this approach, concluding that it offers the best clue yet to the shape of a unified science of mind and action. Sections 1 and 2 lay out the key elements and implications of the approach. Section 3 explores a variety of pitfalls and challenges, spanning the evidential, the methodological, and the more properly conceptual. The paper ends (sections 4 and 5) by asking how such approaches might impact our more general vision of mind, experience, and agency. (shrink)

Mindware: An Introduction to the Philosophy of Cognitive Science invites readers to join in up-to-the-minute conceptual discussions of the fundamental issues, problems, and opportunities in cognitive science. Written by one of the most renowned scholars in the field, this vivid and engaging introductory text relates the story of the search for a cognitive scientific understanding of mind. This search is presented as a no-holds-barred journey from early work in artificial intelligence, through connectionist (artificial neural network) counter-visions, and on to neuroscience, (...) artificial life, dynamics, and robotics. The journey ends with some wide-ranging and provocative speculation about the complex coadaptive dance between mind, culture, and technology. Each chapter opens with a brief sketch of a major research tradition or perspective, followed by short yet substantial critical discussions dealing with key topics and problems. Ranging across both standard philosophical territory and the landscape of cutting-edge cognitive science, Clark highlights challenging issues in an effort to engage readers in active debate. Topics covered include mental causation; machine intelligence; the nature and status of folk psychology; the hardware/software distinction; emergence; relations between life and mind; the nature of perception, cognition, and action; and the continuity (or otherwise) of high-level human intelligence with other forms of adaptive response. Numerous illustrations, text boxes, and extensive suggestions for further reading enhance the text's utility. Helpful appendices provide background information on dualism, behaviorism, identity theory, consciousness, and more. An exceptional text for introductory and more advanced courses in cognitive science and the philosophy of mind, Mindware is also essential reading for anyone interested in these fascinating and ever-changing fields.

In "Mathematical Truth", Paul Benacerraf articulated an epistemological problem for mathematical realism. His formulation of the problem relied on a causal theory of knowledge which is now widely rejected. But it is generally agreed that Benacerraf was onto a genuine problem for mathematical realism nevertheless. Hartry Field describes it as the problem of explaining the reliability of our mathematical beliefs, realistically construed. In this paper, I argue that the Benacerraf Problem cannot be made out. There simply is no intelligible problem (...) that satisfies all of the constraints which have been placed on the Benacerraf Problem. The point generalizes to all arguments with the structure of the Benacerraf Problem aimed at realism about a domain meeting certain conditions. Such arguments include so-called "Evolutionary Debunking Arguments" aimed at moral realism. I conclude with some suggestions about the relationship between the Benacerraf Problem and the Gettier Problem. (shrink)

To what extent are the subjects of our thoughts and talk real? This is the question of realism. In this book, Justin Clarke-Doane explores arguments for and against moral realism and mathematical realism, how they interact, and what they can tell us about areas of philosophical interest more generally. He argues that, contrary to widespread belief, our mathematical beliefs have no better claim to being self-evident or provable than our moral beliefs. Nor do our mathematical beliefs have better claim (...) to being empirically justified than our moral beliefs. It is also incorrect that reflection on the "genealogy" of our moral beliefs establishes a lack of parity between the cases. In general, if one is a moral antirealist on the basis of epistemological considerations, then one ought to be a mathematical antirealist as well. And, yet, Clarke-Doane shows that moral realism and mathematical realism do not stand or fall together -- and for a surprising reason. Moral questions, insofar as they are practical, are objective in a sense that mathematical questions are not. Moreover, the sense in which they are objective can be explained only by assuming practical anti-realism. One upshot of the discussion is that the concepts of realism and objectivity, which are widely identified, are actually in tension. Another is that the objective questions in the neighborhood of questions of logic, modality, grounding, and nature are practical questions too. Practical philosophy should, therefore, take center stage. (shrink)

Ranging across both standard philosophical territory and the landscape of cutting-edge cognitive science, Mindware: An Introduction to the Philosophy of Cognitive Science, Second Edition, is a vivid and engaging introduction to key issues, research, and opportunities in the field.Starting with the vision of mindware as software and debates between realists, instrumentalists, and eliminativists, Andy Clark takes students on a no-holds-barred journey through connectionism, dynamical systems, and real-world robotics before moving on to the frontiers of cognitive technologies, enactivism, predictive coding, and (...) the extended mind. Throughout, he highlights challenging issues in an effort to engage students in active debate. Each chapter opens with a brief sketch of a major research tradition or perspective, followed by concise critical discussions dealing with key topics and problems. (shrink)

Galen Strawson has published several versions of an argument to the effect that moral responsibility is impossible, whether determinism is true or not. Few philosophers have been persuaded by the argument, which Strawson remarks is often dismissed “as wrong, or irrelevant, or fatuous, or too rapid, or an expression of metaphysical megalomania.” I offer here a two-part explanation of why Strawson’s argument has impressed so few. First, as he usually states it, the argument is lacking at least one key premise. (...) The premise in question concerns the very point on which Strawson and many of his contemporary opponents disagree. Strawson will persuade these opponents only when he convinces them of the truth of this crucial premise. Second, Strawson employs a striking conception of responsibility that has not generally been remarked upon. Many might accept that responsibility so conceived is impossible. But there is very different conception of responsibility that appears of great importance to us. To be thoroughly convincing, Strawson will have to show either that this second conception is inadequate or that his argument goes through even given this alternative conception. (shrink)

This book discusses the problem of mathematical knowledge, and its broader philosophical ramifications. It argues that the problem of explaining the (defeasible) justification of our mathematical beliefs (‘the justificatory challenge’), arises insofar as disagreement over axioms bottoms out in disagreement over intuitions. And it argues that the problem of explaining their reliability (‘the reliability challenge’), arises to the extent that we could have easily had different beliefs. The book shows that mathematical facts are not, in general, empirically accessible, contra Quine, (...) and that they cannot be dispensed with, contra Field. However, it argues that they might be so plentiful that our knowledge of them is intelligible. The book concludes with a complementary ‘pluralism’ about modality, logic and normative theory, highlighting its revisionary implications. Metaphysically, pluralism engenders a kind of perspectivalism and indeterminacy. Methodologically, it vindicates Carnap’s pragmatism, transposed to the key of realism. (shrink)

It is commonly suggested that evolutionary considerations generate an epistemological challenge for moral realism. At first approximation, the challenge for the moral realist is to explain our having many true moral beliefs, given that those beliefs are the products of evolutionary forces that would be indifferent to the moral truth. An important question surrounding this challenge is the extent to which it generalizes. In particular, it is of interest whether the Evolutionary Challenge for moral realism is equally a challenge for (...) mathematical realism. It is widely thought not to be. In this paper, I argue that the Evolutionary Challenge for moral realism is equally a challenge for mathematical realism. Along the way, I substantially clarify the Evolutionary Challenge, discuss its relation to more familiar epistemological challenges, and broach the problem of moral disagreement. The paper should be of interest to ethicists because it places pressure on anyone who rejects moral realism on the basis of the Evolutionary Challenge to reject mathematical realism as well. And the paper should be of interest to philosophers of mathematics because it presents a new epistemological challenge for mathematical realism that bears, I argue, no simple relation to Paul Benacerraf's familiar challenge.

Let F be a fact in virtue of which an agent, S, is blameworthy for performing an act of A-ing. We advance a slightly qualified version of the following thesis: -/- (Reason) F is (at some time) a reason for S to feel guilty (to some extent) for A-ing. -/- Leaving implicit the qualification concerning extent, we claim as well: -/- (Desert) S's having this reason suffices for S’s deserving to feel guilty for A-ing. -/- We also advance a third (...) thesis connecting desert of feeling guilty with the fittingness of this response. -/- In light of our three theses, we address several claims that have been made regarding responsibility and desert. We take issue with the divorce of desert from responsibility. We find acceptable a claim regarding blameworthiness and reason to induce guilt, and we defend the idea that it is noninstrumentally good that one who is blameworthy be subject to a fitting feeling of guilt. We argue against a view on which desert of blame has a teleological dimension. (shrink)

Philosophical theories of agency have focused primarily on actions and activities. But, besides acting, we often omit to do or refrain from doing certain things. How is this aspect of our agency to be conceived? This book offers a comprehensive account of omitting and refraining, addressing issues ranging from the nature of agency and moral responsibility to the metaphysics of absences and causation. Topics addressed include the role of intention in intentional omission, the connection between negligence and omission, the distinction (...) between doing and allowing, and the distinction in law between act and omission.

This is a three-part exchange on the relationship between belief and credence. It begins with an opening essay by Roger Clarke that argues for the claim that the notion of credence generalizes the notion of belief. Julia Staffel argues in her reply that we need to distinguish between mental states and models representing them, and that this helps us explain what it could mean that belief is a special case of credence. Roger Clarke's final essay reflects on the (...) compatibility of the previously discussed views with dualist and monist interpretations of our mental states and our ways of modeling them. (shrink)

Skilled activity, such as shaving or dancing, differs in important ways from many of the stock examples that are employed by action theorists. Some critics of the causal theory of action contend that such a view founders on the problem of skilled activity. This paper examines how a causal theory can be extended to the case of skilled activity and defends the account from its critics.

This book presents a provocative new interpretation of what is arguably Nietzsche's most important and most difficult work, Beyond Good and Evil.

Ayant depuis son premier livre exploré son hypothèse d'une naissance de notre langage articulé, humain, à partir de l'expérience de la mort d'autrui comme autre soi-même, Gérard Bucher expose dans un dernier ouvrage les raisons des travaux d'une vie entière.

The preface paradox does not show that it can be rational to have inconsistent beliefs, because preface writers do not have inconsistent beliefs. I argue, first, that a fully satisfactory solution to the preface paradox would have it that the preface writer's beliefs are consistent. The case here is on basic intuitive grounds, not the consequence of a theory of rationality or of belief. Second, I point out that there is an independently motivated theory of belief – sensitivism – which (...) allows such a solution. I sketch a sensitivist account of the preface writer's doxastic state. (shrink)

A good definition of process tracing should highlight what is distinctive about process tracing as a methodology of causal inference. I look at eight criteria that are used to define process tracing in the methodological literature, and I dismiss all eight criteria as unhelpful (some because they are too restrictive, and others because they are vacuous). In place of these criteria, I propose four alternative criteria, and I draw a distinction between process tracing for the ultimate aim of testing a (...) start--end hypothesis versus process tracing as an ultimate end in itself. Although it is clear enough how the former method works, there is still much methodological work to be done in understanding the latter method as a distinctive method of causal inference, I argue.

One effect of information technology is the increasing need to present information visually. The trend raises intriguing questions. What is the logical status of reasoning that employs visualization? What are the cognitive advantages and pitfalls of this reasoning? What kinds of tools can be developed to aid in the use of visual representation? This newest volume on the Studies in Logic and Computation series addresses the logical aspects of the visualization of information. The authors of these specially commissioned papers explore (...) the properties of diagrams, charts, and maps, and their use in problem solving and teaching basic reasoning skills. As computers make visual representations more commonplace, it is important for professionals, researchers and students in computer science, philosophy, and logic to develop an understanding of these tools; this book can clarify the relationship between visuals and information.

Realist ideology critique (RIC) is a strand of political realism recently developed in response to concerns that realism is biased toward the status quo. RIC aims to debunk an individual's belief that a social institution is legitimate by revealing that the belief is caused by that very same institution. Despite its growing prominence, RIC has received little critical attention. In this article, I buck this trend. First, I improve on contemporary accounts of RIC by clarifying its status and the role (...) of motivated reasoning. Second, I show that realist ideology critics face a dilemma: either their account makes deeply implausible epistemological assumptions, or they temper its epistemology at the expense of rendering it toothless. I argue for each horn in turn before revealing the dilemma to be a false one by making a novel distinction between varying strengths of RIC based on their underlying epistemological assumptions. I propose Moderate RIC as a solution: upon discovering that one reason for your belief that a social institution is legitimate is likely malignantly epistemically circular, the belief should undergo further epistemic testing. I respond to three potential objections and suggest that Moderate RIC would make a fruitful addition to political theorists' methodological toolkit. (shrink)

How do intelligent agents spawn and exploit integrated processing regimes spanning brain, body, and world? The answer may lie in the ability of the biological brain to select actions and policies in the light of counterfactual predictions – predictions about what kinds of futures will result if such-and-such actions are launched. Appeals to the minimization of ‘counterfactual prediction errors’ (the ones that would result under various scenarios) already play a leading role in attempts to apply the basic toolkit of the (...) neurocomputational theory known as ‘predictive processing’ to higher cognitive functions such as policy selection and planning. In this paper, I show that this also leads naturally to the discovery and use of extended processing regimes defined across heterogeneous mixtures of biological and non-biological resource. This solves a long-standing puzzle concerning the ‘recruitment’ of the right non-neural processing resources at the right time. It reveals how (and why) human brains spawn and maintain extended human minds. (shrink)

When evaluating theories of causation, intuitions should not play a decisive role, not even intuitions in flawlessly-designed thought experiments. Indeed, no coherent theory of causation can respect the typical person’s intuitions in redundancy (pre-emption) thought experiments, without disrespecting their intuitions in threat-and-saviour (switching/short-circuit) thought experiments. I provide a deductively sound argument for these claims. Amazingly, this argument assumes absolutely nothing about the nature of causation. I also provide a second argument, whose conclusion is even stronger: the typical person’s causal intuitions (...) are thoroughly unreliable. This argument proceeds by raising the neglected question: in what respects is information about intermediate and enabling variables relevant to reliable causal judgment? (shrink)

To most, myths are merely fantastic stories. But for Luc Brisson, one of the great living Plato scholars, myth is a key factor in what it means to be human – a condition of life for all. Essential and inescapable, myth offers a guide for living, forming the core of belonging and group identity. In 1999 Quebec classicist Louis-André Dorion published a series of French conversations with Brisson on the idea of myth. In Making Sense of Myth Gerard Naddaf (...) offers an extended and updated English translation of these conversations, as well as a new set of discussions between himself and Brisson. Beginning with Brisson's childhood in the village of Saint-Esprit, Quebec, through his education as a gifted child in minor seminaries starting at age eleven, and continuing with his years in Paris, first as a graduate student and later at the Centre national de la recherche scientifique (CNRS), Brisson tells the story of his escape from an all-encompassing myth – the one promulgated by the Roman Catholic Church. The philosopher situates Quebec society as inseparable from the history of the Catholic Church in Quebec, and argues that this correlation offers a perfect paradigm of myth and mythmaking. Naddaf’s introduction and afterword contextualize the conversations by discussing Brisson’s and Plato’s understanding of the origin and meaning of myth, elaborating on the role of myth in anthropogeny, in the creation of selfhood, and in multiculturalism. Making Sense of Myth promises both a philosophy of myth and a philosophy of life, one inspired by Brisson’s lifelong engagement with the great Western philosopher Plato. (shrink)

All these specialist aspects of one life are different facets of the intellectual diamond which scintillates in the huge quarry of The Bertrand Russell Archives at McMaster University, Hamilton, Ontario.

Are OCypersonsOCO physical things, members of the species homo sapiens which exist solely in materialist form, continuous in structure with other living things? Or is the issue a more complex one: are there more dimensions to being a person than mere physical, biological existence?

In this wide-ranging essay, the author addresses various aspects of the issue, including the history of self and identity. The (...) ancient tradition of dualism is rejected in favour of a straightforward holistic and naturalistic account of selfhood; it is argued that the mind arises in an emergent sense from the body and personal identity is best expressed in terms of a self-reflective and meaningful narrative.
