Noam Chomsky and Frances Egan argue that David Marr’s computational theory of vision is not intentional, claiming that the formal scientific theory does not include description of visual content. They also argue that the theory is internalist in the sense of not describing things physically external to the perceiver. They argue that these claims hold for computational theories of vision in general. Beyond theories of vision, they argue that representational content does not figure as a topic within formal computational (...) theories in cognitive science. I demonstrate that Chomsky’s and Egan’s claims about Marr’s theory are false. Marr’s computational theory contains a mathematical theory of visual content, based on empirical psychophysical evidence. It also contains mathematical descriptions of distal physical surfaces and objects, and of their optic projection to the perceiver. Much computational research on vision contains these types of intentional and externalist components within the formal, mathematical, theories. Chomsky’s and Egan’s claims demonstrate inadequate study and understanding of Marr’s work and other research in this area. Computational theories of vision, by containing empirically based mathematical theories of visual content, to this extent present naturalizations of semantics. (shrink)

An agent often does not have precise probabilities or utilities to guide resolution of a decision problem. I advance a principle of rationality for making decisions in such cases. To begin, I represent the doxastic and conative state of an agent with a set of pairs of a probability assignment and a utility assignment. Then I support a decision principle that allows any act that maximizes expected utility according to some pair of assignments in the set. Assuming that computation of (...) an option's expected utility uses comprehensive possible outcomes that include the option's risk, no consideration supports a stricter requirement. (shrink)

The centrality of death rituals has in anthropologically informed studies of Buddhism been little documented. The current volume brings together a range of perspectives on Buddhist death rituals including ethnographic, textual, historical and theoretically informed accounts, and presents the diversity of the Buddhist funeral cultures of mainland Southeast Asia and China. It arises out of the University of Bristol's Centre for Buddhist Studies research project Buddhist Death Rituals in Southeast Asia and China, funded by the United Kingdom's Arts and Humanities (...) Research Council. This project involved extensive new research in Thailand, Laos and China. Other items from that project included several public exhibitions, extensive stills photographs, and several video films. The project-team produced two 30 minutes films on the ghost festival in Laos and China, one on urban funerals in Chiang Mai (Thailand) and several shorter clips dealing with funeral cultures in Laos, Thailand and China. Most of this material (and an extensive bibliography on the topic) is available free of charge from the project website located at the webpage of the Department of Theology and Religious Studies (Centre for Buddhist Studies) at the University of Bristol.

Descartes is widely portrayed as the arch proponent of “the epistemological transparency of thought” (or simply, “Transparency”). The most promising version of this view—Transparency-through-Introspection—says that introspecting (i.e., inwardly attending to) a thought guarantees certain knowledge of that thought. But Descartes rejects this view and provides numerous counterexamples to it. I argue that, instead, Descartes’s theory of self-knowledge is just an application of his general theory of knowledge. According to his general theory, certain knowledge is acquired only through clear and distinct (...) intellection. Thus, in his view, certain knowledge of one’s thoughts is acquired only through clear and distinct intellection of one’s thoughts. Introspection is a form of intellection and it can be clear and distinct. Ordinarily, however, introspection isn’t clear and distinct but is instead confused with dubitable perceptions of bodies. To make introspection clear and distinct, we need to “sharply separate” it from all perceptions of bodies by doubting all perceptions of bodies. Without such radical doubt, introspection remains confused and we lack certain knowledge not just of the specific features of our thoughts, but even of the minimal claim that a thought exists. Far from being the high priest of Transparency, Descartes is radically opposed to it. (shrink)

This paper presents the view that tropes can change, and so are not individuated by their determinate qualitative characters. On the view I have in mind, a trope is at any given time fully determinate, but can change qualitatively within the bounds set by a determinable essence. A charge trope, for example, must at any time have some exact intensity, but can survive changes in intensity. My argument, roughly, is this: Objects can change, and tropes are the parts of objects (...) that change (in a special sense of ‘part’), so tropes can change too. After some preliminaries, I present the argument carefully and discuss the operant notions. I then discuss each premise in turn. I respond to the charge that the view isn't realist, and to objections based on identity‐conditions for tropes. I describe both substratum‐ and bundle‐theoretic versions of the view, and finally, show what the view buys us. (shrink)

The paper asks under what conditions deductive reasoning transmits justification from its premises to its conclusion. It argues that both standard externalist and standard internalist accounts of this phenomenon fail. The nature of this failure is taken to indicate the way forward: basic forms of deductive reasoning must justify by being instances of 'blind but blameless' reasoning. Finally, the paper explores the suggestion that an inferentialist account of the logical constants can help explain how such reasoning is possible.

People generally accept that there is causation by omission—that the omission of some events cause some related events. But this acceptance elicits the selection problem, or the difficulty of explaining the selection of a particular omissive cause or class of causes from the causal conditions. Some theorists contend that dependence theories of causation cannot resolve this problem. In this paper, we argue that the appeal to norms adequately resolves the selection problem for dependence theories, and we provide novel experimental evidence (...) for it. (shrink)

In epistemology and in philosophy of language there is fierce debate about the role of context in knowledge, understanding, and meaning. Many contemporary epistemologists take seriously the thesis that epistemic vocabulary is context-sensitive. This thesis is of course a semantic claim, so it has brought epistemologists into contact with work on context in semantics by philosophers of language. This volume brings together the debates, in a set of twelve specially written essays representing the latest work by leading figures in the (...) two fields. All future work on contextualism will start here. Contributors: Kent Bach, Herman Cappelen, Andy Egan, Michael Glanzberg, John Hawthorne, Ernest Lepore, Peter Ludlow, Peter Pagin, Georg Peter, Paul M. Pietroski, Gerhard Preyer, Jonathan Schaffer, Jason Stanley, Brian Weatherson, Timothy Williamson. (shrink)

This article has two objectives. First, and in particular, it seeks to reinterpret the ostracism procedure of early democratic Athens. Since Aristotle, this has been understood as a rational, political weapon of collective defense, intended to expel from Athens a disproportionately powerful individual. In this article, by putting emphasis on themateriality, gestures, and location of ostraka-casting, I propose instead that the institution can more fruitfully be understood as a ritual enactment of civic unity. Second, and more generally, I hope to (...) explore the frames within which early Athenian democracy is placed: while Greek kingship and tyranny (i.e. “primitive” polities) have been very successfully explored through anthropological and cross-cultural comparison, Greek democracy for the most part has remained in the domains of the institutional historian and political theorist. Taking a phenomenological and comparative approach, this article asks how the citizens of early democratic Athens experienced and comprehended their new sovereignty and the invented procedures of mass decision-making through which it was expressed.

Like Plato, Protagoras held that young children learn virtue from fine examples in poetry. Unlike Plato, Protagoras taught adults by correcting the diction of poets. In this paper I ask what his standard of correctness might be, and what benefit he intended his students to take from exercises in correction. If his standard of correctness is truth, then he may intend his students to learn by questioning the content of poems; that would be suggestive of Plato’s program in Republic III. (...) But his standard is more likely to be the accurate use of language; in that case he would intend his students to learn to express their thoughts clearly enough that their audience would understand what they were saying. That standard would be independent of the truth of what they are saying; and that would be a precursor to modern techniques by which we try to teach speaking and writing. Truth is not so easy to escape, however, and we shall see that Protagoras’ exercise must assume that the poet is trying to tell the truth. (shrink)

The Gamer’s Dilemma challenges us to justify the moral difference between enacting virtual murder and virtual child molestation in video games. The Dilemma relies for its argumentative force on the claim that there is an intuitive moral difference between these acts, with the former intuited as morally acceptable and the latter as morally unacceptable. However, there has been no empirical investigation of these claims. To explore these issues, we developed an experimental survey study in which participants were asked to reflect (...) on imaginary video game scenarios as part of a 2 (undertake virtual murder or molestation) X 2 (against an adult or child) X 2 (in a high or low realism virtual environment) factorial design. We found that there was a significant difference between people’s views about virtual murder and virtual molestation. Whether the virtual act was performed against an adult or child was non-significant in most conditions, whereas whether it was performed in a high or low realism virtual environment was significant in most conditions. Gender did not impact these results, whereas perceived gaming experience, hours of video game play per week, and integrity did. These results provide an empirical grounding for future discussions of the Gamer's Dilemma. (shrink)

You’re imagining, in the course of a different game of make-believe, that you’re a bank robber. You don’t believe that you’re a bank robber. You are moved to point your finger, gun-wise, at the person pretending to be the bank teller and say, “Stick ‘em up! This is a robbery!”.

We argue for an imaginative analog of desire from premises about imaginative engagement with fiction. There's a bit about the paradox of fiction, too.

In _Matter and Consciousness_, Paul Churchland presents a concise and contemporary overview of the philosophical issues surrounding the mind and explains the main theories and philosophical positions that have been proposed to solve them. Making the case for the relevance of theoretical and experimental results in neuroscience, cognitive science, and artificial intelligence for the philosophy of mind, Churchland reviews current developments in the cognitive sciences and offers a clear and accessible account of the connections to philosophy of mind. For (...) this third edition, the text has been updated and revised throughout. The changes range from references to the iPhone's "Siri" to expanded discussions of the work of such contemporary philosophers as David Chalmers, John Searle, and Thomas Nagel. Churchland describes new research in evolution, genetics, and visual neuroscience, among other areas, arguing that the philosophical significance of these new findings lies in the support they tend to give to the reductive and eliminative versions of materialism. Matter and Consciousness, written by the most distinguished theorist and commentator in the field, offers an authoritative summary and sourcebook for issues in philosophy of mind. It is suitable for use as an introductory undergraduate text. (shrink)

In his middle and later periods one of Wittgenstein’s concerns was perception. This is, of course, precisely what one would expect given his obvious interest then in the notion of experience and in the language we employ to describe and express our experiences. However, the passage which has attracted most attention is the discussion in sec. XI of part II of Philosophical Investigations which is concerned with “seeing as”, or “aspect seeing”. In this paper the examples that Wittgenstein uses are (...) examined, and some puzzles about them raised. It is suggested that Wittgenstein’s aim is to discredit some supposedly mistaken accounts of what ‘seeing as’ is. These mistaken accounts are supposed to made by Gestalt psychologists such as Kohler, and traditional sense-datum theorists. It is further argued that Wittgenstein’s criticisms are not uniformly cogent. It is, though, conceded that this rich and original passage contains far more than the elements investigated here, so much more needs to be scrutinised. (shrink)

A philosophical account of risk, such as this book provides, states what risk is, which attitudes to it are rational, and which acts affecting risks are rational. Attention to the nature of risk reveals two types of risk, first, a chance of a bad event, and, second, an act’s risk in the sense of the volatility of its possible outcomes. The distinction is normatively significant because different general principles of rationality govern attitudes to these two types of risk. Rationality strictly (...) regulates attitudes to the chance of a bad event and is more permissive about attitudes to an act’s risk. Principles of rationality governing attitudes to risk also justify evaluating an act according to its expected utility given that the act’s risk, if any, belongs to every possible outcome of the act. For a rational ideal agent, the expected utilities of the acts available in a decision problem explain the agent’s preferences among the acts. Maximizing expected utility is just following preferences among the acts. This view takes an act’s expected utility, not just as a feature of a representation of preferences among acts, but also as a factor in the explanation of preferences among acts. The view extends to evaluations of combination of acts, either simultaneous or in a sequence. It takes account of an agent’s attitudes to an act’s risk without weakening the standard of expected-utility maximization. The book’s theory of risk also grounds a justification of the risk-return evaluation of investments that finance advances, and a generalized version of this type of evaluation that a professional may use to advise clients about risks and that a government regulatory agency may use to make decisions about risks on behalf of the public.

In their article ’Is Pregnancy a Disease? A Normative Approach’, Anna Smajdor and Joona Räsänen contend that, on several of the most prominent accounts of disease, pregnancy should be considered a disease. More specifically, of the five accounts they discuss, each renders pregnancy a disease or suffers serious conceptual problems otherwise. They take issue specifically with the dysfunction account of disease and argue that it suffers several theoretical difficulties. In this response, we focus on defending the dysfunction account against their (...) main objections and show why a version of the dysfunction account is viable on account of the indispensability of normativity in biology and medicine. After disarming their main objections to the dysfunction account, we briefly respond to their treatment of the normality of pregnancy and then draw a distinction between adverse symptoms and underlying causes to show why even though pregnancy may have ’disease-like’ features, it is not a disease.

This handbook provides both an overview of state-of-the-art scholarship in philosophy of science, as well as a guide to new directions in the discipline. Section I contains broad overviews of the main lines of research and the state of established knowledge in six principal areas of the discipline, including computational, physical, biological, psychological and social sciences, as well as general philosophy of science. Section II covers what are considered to be the traditional topics in the philosophy of science, such as (...) causation, probability, models, ethics and values, and explanation. Section III identifies new areas of investigation that show promise of becoming important areas of research, including the philosophy of astronomy and astrophysics, data, complexity theory, neuroscience, simulations, post-Kuhnian philosophy, post-empiricist epistemology, and emergence. Most chapters are accessible to scientifically educated non-philosophers as well as to professional philosophers, and the contributors - all leading researchers in their field -- bring diverse perspectives from the North American, European, and Australasian research communities. This volume is an essential resource for scholars and students. (shrink)

This chapter presents an opinionated account of how to understand the contributions of experience, especially with respect to the role of cognitive science, in developing and assessing metaphysical theories of reality. I develop a methodological basis for the idea that, independently of work in experimental philosophy focused on explications of concepts, contemporary metaphysical theories with a role for experiential evidence can be fruitfully connected to empirical work in psychology, especially cognitive science. My argument is not that cognitive science should replace (...) the metaphysician’s use of a priori theorizing and ordinary experience as a guide to metaphysical reality. Rather, we should enrich our perspective on a priori theorizing and ordinary experience as a guide to metaphysical reality by drawing on any relevant work in cognitive science. (shrink)

The role of Amartya Sen's early work on famine notwithstanding, food security is generally seen as but one capability among many for scholars writing in development ethics. The early literature on the ethics of hunger is summarized to show how Sen's Poverty and Famines was written in response to debates of past decades, and a brief discussion of food security as a capability follows. However, Sen's characterization of smallholder food security also supports the development of agency in both a political (...) and an economic sense. Economic agency is discussed and tied to longstanding literatures on the moral significance of farming within political economy. Finally, while the newly emergent literature on food sovereignty includes many themes, it is shown to be re-articulating arguments that stress smallholder's economic agency as a development goal. This pattern of argument thus provides a way to reconcile at least some of the claims being advanced under the banner of food sovereignty with the human development.. (shrink)

The Scottish philosopher David Hume (1711-1776) is widely regarded as the greatest and most significant English-speaking philosopher and often seen as having had the most influence on the way philosophy is practiced today in the West. His reputation is based not only on the quality of his philosophical thought but also on the breadth and scope of his writings, which ranged over metaphysics, epistemology, morals, politics, religion, and aesthetics. The Handbook's 38 newly commissioned chapters are divided into six parts: Central (...) Themes; Metaphysics and Epistemology; Passion, Morality and Politics; Aesthetics, History, and Economics; Religion; Hume and the Enlightenment; and After Hume. The volume also features an introduction from editor Paul Russell and a chapter on Hume's biography. (shrink)

By applying research in artificial intelligence to problems in the philosophy of science, Paul Thagard develops an exciting new approach to the study of scientific reasoning. This approach uses computational ideas to shed light on how scientific theories are discovered, evaluated, and used in explanations.

Paul Moser's book defends what has been an unfashionable view in recent epistemology: the foundationalist account of knowledge and justification. Since the time of Plato philosophers have wondered what exactly knowledge is. This book develops a new account of perceptual knowledge which specifies the exact sense in which knowledge has foundations. The author argues that experiential foundations are indeed essential to perceptual knowledge, and he explains what knowledge requires beyond justified true beliefs. In challenging prominent sceptical claims that we (...) have no justified beliefs about the external world, the book outlines a theory of rational belief. (shrink)
