The phenomenon of disagreement has recently been brought into focus by the debate between contextualists and relativist invariantists about epistemic expressions such as ‘might’, ‘probably’, indicative conditionals, and the deontic ‘ought’. Against the orthodox contextualist view, it has been argued that an invariantist account can better explain apparent disagreements across contexts by appeal to the incompatibility of the propositions expressed in those contexts. This paper introduces an important and underappreciated phenomenon associated with epistemic expressions — a phenomenon that we call (...) reversibility. We argue that the invariantist account of disagreement is incompatible with reversibility, and we go on to show that reversible sentences cast doubt on the putative data about disagreement, even without assuming invariantism. Our argument therefore undermines much of the motivation for invariantism, and provides a new source for constraints on the proper explanation of purported data about disagreement. (shrink)

Understanding consciousness is one of the central scientific challenges of our time. This book presents Andy Ross's recent work and discusses a range of perspectives on the core issues. The chapters are based on texts written for a variety of occasions and audiences. Reading them in order, one senses a growing clarity in the articulation of the new ideas, some of which are deep and rather subtle, and glimpses the outlines of a dynamic field. Ross has taken (...) pains to unify the collection and make the main thread clearly visible. His new ideas are of fundamental importance, and readers who grapple with them should gain insight that amply rewards the effort. (shrink)

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.

“There’s no disputing about taste.” That’s got a nice ring to it, but it’s not quite the ring of truth. While there’s definitely something right about the aphorism – there’s a reason why it is, after all, an aphorism, and why its utterance tends to produce so much nodding of heads and muttering of “just so” and “yes, quite” – it’s surprisingly difficult to put one’s finger on just what the truth in the neighborhood is, exactly. One thing that’s pretty (...) clear is that what’s right about the aphorism, that there’s no disputing about taste, isn’t that there’s no disputing about taste. There’s heaps of disputing about taste. People engage in disputes about which movies, music, paintings, literature, meals, furniture, architectural styles, etc. are good, beautiful, tasty, fun, elegant, ugly, disgusting, etc. all the time. This is obvious to anyone who has watched dueling-movie-critics shows, read theater reviews, or negotiated with a group or partner about which movie or restaurant to go to, or which sofa or painting to put in the living room. It takes great care and good aim to fling a brick without hitting somebody who’s engaged in a dispute about taste. (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)

Original essays by leading philosophers of science explore the question of whether metaphysics can and should be naturalized--conducted as part of natural science.

"Expanding the Palace of Torah" offers a broad philosophical overview of the challenges the women's revolution poses to Orthodox Judaism, and Orthodox Judaism's response to those challenges.

The Handmaid’s Tale depicts a United States taken over by a fundamentalist dictatorship called Gilead that also resembles Plato’s ideal city. Attempts to explain Gilead’s debt to Plato face two challenges. First, aspects of Gilead that recall Plato also contain features that differ, at times dramatically, from the Platonic original. Second, Gilead invokes distorted versions of ideas from philosophies other than Plato’s. I explore two ways of making sense of Gilead’s distorted philosophical appropriations. The explanations differ over whether such distortions (...) are best explained by the nature of the philosophies they misrepresent, or by the nature of Gilead. The explanation that emphasizes Gilead’s own agency is ultimately best able to make sense of how illiberal regimes misappropriate philosophical concepts, both in the novel and in reality, in order to limit the political imagination of their subjects.

We examine moving spotlight theories of time: theories according to which there are past and future events and an objective present moment. In Section 1, we briefly discuss the origins of the view. In Section 2, we describe the traditional moving spotlight view, which we understand as an ‘enriched’ B-theory of time, and raise some problems for that view. In the next two sections, we describe versions of the moving spotlight view that we think are better and which solve those (...) problems. In Section 3, we describe a version of the view that combines permanentism – the thesis that all things always exist – with propositional temporalism, the thesis that some propositions are sometimes true and sometimes false. In Section 4, we discuss a version of the view that is like an ‘enriched’ presentism. We conclude with some brief thoughts on issues that remain outstanding. (shrink)

The divine attributes of immensity and omnipresence have been integral to classical Christian confession regarding the nature of the triune God. Divine immensity and omnipresence are affirmed in doctrinal standards such as the Athanasian Creed (c. 500), the Fourth Lateran Council (1215), the Council of Basel (1431–49), the Second Helvetic Confession (1566), the Westminster Confession of Faith (1647), the Second London Baptist Confession (1689), and the First Vatican Council (1869–70). In the first section of this chapter, I offer a brief (...) historical overview of divine immensity and divine omnipresence in the Christian tradition. I then offer a brief taxonomy of contemporary models of divine omnipresence in the philosophical and theological landscape. In the second, more constructive section, I aim to gesture toward the retrieval of several classical insights regarding immensity and omnipresence that remain unexplored in contemporary analytic work.

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)

Are artists, designers and musicians inventors? Or does the invention originate from scientific discovery alone? Ecologies of Invention is the first collection of essays that brings together writers and scholars of international standing from the University of Sydney and beyond to examine assumptions underlying notions of inventiveness. The writers explain how inventiveness borne out of aesthetic ambitions is impacting on and changing our culture and society. Ecologies of Invention describes the articulation of inventive capacities across disciplines and across multiple scales, (...) from personal capacities to the social, spatial and network configurations that drive people to produce inventions. The book poses new questions for scholars, artists, architects, designers, historians, engineers, scientists, lawyers and economists about the nature, origins and processes of invention. 'This is a challenging book which confronts traditional thinking around creativity and inventiveness and raises issues that need serious debate'. Barry Jones AO. (shrink)

The study of social norms sprawls across all of the social sciences but the the concept lacks a unified conception and formal theory. We synthesize an account that can be applied generally, at the social scale of analysis, and can be applied to empirical evidence generated in field and lab experiments. More specifically, we provide new analysis on representing norms for application in empirical political science, and in parts of economics that do not follow the recent trend among some behavioral (...) economists to build models of the cognitive and motivational states of individuals taken “one at a time”. Foundational sources for our project are Bicchieri (2006, 2017), Kuran (1995), and Stirling (2012, 2016). From Bicchieri take that a norm exists in a social structure when a significant networked subset of individuals share descriptive and injunctive expectations that it regulates their interactions. From Kuran we take the insight that prevailing norms may come to be widely disliked by participants in networks but survive because norm suppress public displays of disenchantment. From Stirling we apply conditional game theory (CGT) to provide the technical resources for building our model of a norm-regulated social interaction. The example we use is a multi-player Investment/Trust Game. (shrink)

A very simple contextualist treatment of a sentence containing an epistemic modal, e.g. a might be F, is that it is true iff for all the contextually salient community knows, a is F. It is widely agreed that the simple theory will not work in some cases, but the counterexamples produced so far seem amenable to a more complicated contextualist theory. We argue, however, that no contextualist theory can capture the evaluations speakers naturally make of sentences containing epistemic modals. If (...) we want to respect these evaluations, our best option is a relativist theory of epistemic modals. On a relativist theory, an utterance of a might be F can be true relative to one context of evaluation and false relative to another. We argue that such a theory does better than any rival approach at capturing all the behaviour of epistemic modals. (shrink)

In this paper I analyse the implications of “flattening” the curve for long-term care residents in the Province of Ontario, Canada during the first wave of the SARS-CoV-2/COVID-19 pandemic. I then question what the role of healthcare systems are in the response to public health emergencies and problematize their status as entities in need of protection. The ethical implications of this are discussed in light of potential challenges raised by climate change.

The understanding of the primary-secondary quality distinction has shifted focus from the mechanical philosophers’ proposal of primary qualities as explanatorily fundamental to current theorists’ proposal of secondary qualities as metaphysically perceiver dependent. The chapter critically examines this shift and current arguments to uphold the primary-secondary quality distinction on the basis of the perceiver dependence of color; one focus of the discussion is the role of qualia in these arguments. It then describes and criticizes reasons for characterizing color, smell, taste, sound, (...) and warmth and color as secondary qualities on the basis of our commonsense divisions among sensory modalities; Grice’s proposal for distinguishing among the sensory modalities is focal here. The general conclusion is that reasons for drawing the primary-secondary quality distinction are unconvincing. (shrink)

I think that there are good reasons to adopt a relativist semantics for epistemic modal claims such as ``the treasure might be under the palm tree'', according to which such utterances determine a truth value relative to something finer-grained than just a world (or a <world, time> pair). Anyone who is inclined to relativise truth to more than just worlds and times faces a problem about assertion. It's easy to be puzzled about just what purpose would be served by assertions (...) of this kind, and how to understand what we'd be up to in our use of sentences like ``the treasure might be under the palm tree'', if they have such peculiar truth conditions. After providing a very quick argument to motivate a relativist view of epistemic modals, I bring out and attempt to resolve this problem in making sense of the role of assertions with relativist truth conditions. Solving this problem should be helpful in two ways: first, it eliminates an apparently forceful objection to relativism, and second, spelling out the relativist account of assertion and communication will help to make clear just what the relativist position is, exactly, and why it's interesting.

This chapter examines the spectrum inversion hypothesis as an argument against certain kinds of account of what it’s like to be conscious of color. The hypothesis aims to provide a counterexample to accounts of what it’s like to be conscious of color in non-qualitative terms, as well as to accounts of what it’s like to be conscious of color in terms of the representational content of conscious visual states (which, according to some philosophers, is in turn given an account in (...) non-qualitative terms). I explain the hypothesis’s reasoning in sections 1 and 2. I then take up background issues: since the counterexample provided by the hypothesis is typically given as a possibility rather than an actuality, I briefly discuss the kind of possibility involved in section 3, and the methodologies used to evaluate the plausibility of possibilities in section 4. In section 5, I describe some general considerations that are commonly used against the spectrum inversion hypothesis. I take up attempts to support the hypothesis with findings from color science in section 6. I end with comments skeptical of both the motivation for the spectrum inversion hypothesis and the methodology used to support it. (shrink)

The notion of a global state of consciousness is an increasingly important construct in the science of consciousness. However, exactly what a global state of consciousness is remains poorly understood. In this paper I offer an account of global states of consciousness as consciousness-related capacity modulations. On this view global states are not themselves phenomenal states – they are not occurring experiences. Rather, they are states that specify which of a creature’s overall consciousness-related capacities are currently online. Given that the (...) search for the neural correlates of consciousness, as it is currently conceived, is the search for the neural basis of occurrent experiences, the NCC framework is incapable of revealing the neural basis of global states. As such, a mature science of consciousness will need to move beyond the search for NCCs, as that project is currently conceived. (shrink)

The moral status of animals is a subject of controversy both within and beyond academic philosophy, especially regarding the question of whether and when it is ethical to eat meat. A commitment to animal rights and related notions of animal protection is often thought to entail a plant-based diet, but recent philosophical work challenges this view by arguing that, even if animals warrant a high degree of moral standing, we are permitted - or even obliged - to eat meat. (...) class='Hi'>Andy Lamey provides critical analysis of past and present dialogues surrounding animal rights, discussing topics including plant agriculture, animal cognition, and in vitro meat. He documents the trend toward a new kind of omnivorism that justifies meat-eating within a framework of animal protection, and evaluates for the first time which forms of this new omnivorism can be ethically justified, providing crucial guidance for philosophers as well as researchers in culture and agriculture.

Paul Churchland does not open his latest book,The Engine of Reason, the Seat of the Soul, modestly. He begins by announcing, “This book is about you. And me … More broadly still, it is about every creature that ever swam, or walked, or flew over the face of the Earth” (p. 3). A few sentences later, he says, “Fortunately, recent research into neural networks … has produced the beginnings of a real understanding of how the biological brain works—a real understanding, (...) that is, of howyouwork, and everyone else like you” (p. 3). The implicit identification here of “me and you and everyone” with “the biological brain” might lead an uncharitable reader to view Churchland's book as “Eliminativism for the non-specialist,” that is, as an attempt to popularize the view of the mindbody problem with which, among his professional peers, Churchland has long been identified. However, I think that such a readingwouldbe uncharitable. He is, of course, frequently sceptical about the utility of folk psychology, but in this book he is much less concerned to disparage folk psychology as a failedtheory(by contrast with, for example, the arguments in Churchland 1979) than to urge the more modest view that the more we understand the brain, the better we shall be at helping those whose brains are damaged in ways that interfere seriously with the fulfilment of their lives. Hence, I am inclined to take him at his word when he says in the Preface that “The book is motivated first of all by sheer excitement over the new picture that is now emerging … [and] … also by the idea that this is information that the public needs to know” (p. xi). What excites Churchland so, at least overtly, is not the negative thesis he has defended elsewhere that folk-psychological terms fail to refer; his enthusiasm is mainly reserved for the positive thesis that minds are, essentially, interacting assemblies of recurrent neural networks. It is therefore this positive thesis, and Churchland's defence of it, that I will assess in the following discussion. (shrink)

Problems about the accidental properties of properties motivate us--force us, I think--not to identify properties with the sets of their instances. If we identify them instead with functions from worlds to extensions, we get a theory of properties that is neutral with respect to disputes over counterpart theory, and we avoid a problem for Lewis's theory of events. Similar problems about the temporary properties of properties motivate us--though this time they probably don't force us--to give up this theory as well, (...) and to identify properties with functions from world, time pairs to extensions. Again, the replacement theory is neutral with respect to a metaphysical dispute that the old theory (arguably) forces us to take a stand on--the dispute over whether objects have temporal parts. It also allows us to give a smoother semantics for predication, to better accommodate our intuitions about which objects temporary properties are properties of, and to make temporally self-locating beliefs genuinely self -locating.

There is a lot that we don't know. That means that there are a lot of possibilities that are, epistemically speaking, open. For instance, we don't know whether it rained in Seattle yesterday. So, for us at least, there is an epistemic possibility where it rained in Seattle yesterday, and one where it did not. What are these epistemic possibilities? They do not match up with metaphysical possibilities - there are various cases where something is epistemically possible but not metaphysically (...) possible, and vice versa. How do we understand the semantics of statements of epistemic modality? The ten new essays in this volume explore various answers to these questions, including those offered by contextualism, relativism, and expressivism. (shrink)

Mental fictionalism is not the benign view that we may better understand the mind if we think of mental states as something like useful fictions, but the more radical view that mental states just are useful fictions. This paper argues that, if one were to treat mental states as a kind of fiction, the genre of fiction best suited to this purpose would be fantasy make-believe, in which magic is a central feature. After defending a promising fictionalist account of mental (...) discourse as a kind of prop-oriented make believe against recent criticism, the paper ultimately concludes that mental fictionalism faces further, potentially insurmountable, challenges. Most significantly, there is a problematic disanalogy between folk psychology and fiction: our mental state attributions aim to track truth, and this crucial aspect of our mental discourse cannot be captured if we interpret it as a kind of fictional discourse. For this and other reasons, the cost of adopting mental fictionalism likely outweighs its benefits. Whether or not these problems can be resolved, there is still much to be gained from taking mental fictionalism seriously: in doing so we may illuminate several important features of our own folk psychology that often go unnoticed.

Many philosophers (myself included) have been converted to causal decision theory by something like the following line of argument: Evidential decision theory endorses irrational courses of action in a range of examples, and endorses “an irrational policy of managing the news”. These are fatal problems for evidential decision theory. Causal decision theory delivers the right results in the troublesome examples, and does not endorse this kind of irrational news-managing. So we should give up evidential decision theory, and be causal decision (...) theorists instead. Unfortunately, causal decision theory has its own family of problematic examples for which it endorses irrational courses of action, and its own irrational policy that it is committed to endorsing. These are, I think, fatal problems for causal decision theory. I wish that I had another theory to offer in its place. (shrink)

Cognitive approaches contribute to our understanding of delusions by providing an explanatory framework that extends beyond the personal level to the sub personal level of information-processing systems. According to one influential cognitive approach, two factors are required to account for the content of a delusion, its initial adoption as a belief, and its persistence. This chapter reviews Bayesian developments of the two-factor framework.

Unconscious Thought Theory posits that a period of distraction after information acquisition leads to unconscious processing which enhances decision making relative to conscious deliberation or immediate choice . Support thus far has been mixed. In the present study, artificial grammar learning was used in order to produce measurable amounts of conscious and unconscious knowledge. Intermediate phases were introduced between training and testing. Participants engaged in conscious deliberation of grammar rules, were distracted for the same period of time, or progressed immediately (...) from training to testing. No differences in accuracy were found between intermediate phase groups acting on decisions made with meta-cognitive awareness . However, the accuracy of guess responses was significantly higher after distraction relative to immediate progression or conscious deliberation. The results suggest any beneficial effects of ‘unconscious thought’ may not always transfer to conscious awareness. (shrink)

On many of the idealized models of human cognition and behavior in use by philosophers, agents are represented as having a single corpus of beliefs which (a) is consistent and deductively closed, and (b) guides all of their (rational, deliberate, intentional) actions all the time. In graded-belief frameworks, agents are represented as having a single, coherent distribution of credences, which guides all of their (rational, deliberate, intentional) actions all of the time. It's clear that actual human beings don't live up (...) to this idealization. The systems of belief that we in fact have are fragmented. Rather than having a single system of beliefs that guides all of our behavior all of the time, we have a number of distinct, compartmentalized systems of belief, different ones of which drive different aspects of our behavior in different contexts. It's tempting to think that, while of course people are fragmented, it would be better (from the perspective of rationality) if they weren't, and the only reason why our fragmentation is excusable is that we have limited cognitive resources, which prevents us from holding too much information before our minds at a time. Give us enough additional processing capacity, and there'd be no justification for any continued fragmentation. I argue that this is not so. There are good reasons to be fragmented rather than unified, independent of the limitations on our available processing power. In particular, there are ways our belief-forming mechanisms—including our perceptual systems—could be constructed that would make it better to be fragmented than to be unified. And there are reasons to think that some of our belief-forming mechanisms really are constructed that way. (shrink)

Very often, different people, with different constitutions and comic sensibilities, will make divergent, conflicting judgments about the comic properties of a given person, object, or event, on account of those differences in their constitutions and comic sensibilities. And in many such cases, while we are inclined to say that their comic judgments are in conflict, we are not inclined to say that anybody is in error. The comic looks like a poster domain for the phenomenon of faultless disagreement. I argue (...) that the kind of theory that does the best job of accounting for the appearance of faultless disagreement is a de se version of a response-dependence account, according to which thinking that x is funny is self-attributing a property of the type, being disposed to have R to x in C.
