Tight correlations between mental states and brain states have been observed time and again within the ethology of biologically ingrained animal behaviors, the comparative psychology of animal minds, the evolutionary psychology of mental adaptations, the behavioral genetics of inherited mental traits, the developmental psychology of the maturing mind, the psychopharmacology of mind-altering substances, and cognitive neuroscience more generally. They imply that our mental lives are only made possible because of brain activity—that having a functioning brain is a necessary condition for (...) having conscious experiences. This mind-brain dependence thesis yields predictions that have been spectacularly confirmed by the evidence, whereas its antithesis has been massively disconfirmed—at least so long as it is not formulated so vaguely as to yield no specific empirical consequences at all. Dualists are thus forced to make a difficult choice: either retain a belief in personal survival at the expense of ignoring or dismissing the implications of our best evidence, or accept those implications at the expense of acknowledging that the prospects for personal survival are extremely dim. -/- 1.

The failure of five psychical researchers to confront my critique of Bigelow Institute contest-winning essays with counterpoints or concessions responsive to its novel criticisms is disappointing. Their defensive and scattershot reply lost sight of whether the critiqued essays met their directive to provide "hard evidence 'beyond a reasonable doubt'" of the survival of human consciousness. In the critique I also questioned the scientific validity of seeking ostensible evidence for discarnate personal survival without giving due care to potential evidence against it, (...) for no scientific (or even legal) investigation of evidence tips the scales in favor of a preordained conclusion by simply never adding any opposing items to the opposite scale. Survival researchers, though, have consistently proceeded in this partisan way. Those who claim that science should expand its metaphysically conservative picture to include things otherwise not known to exist assume the burden of showing what they claim. My interlocutors' almost exclusively testimonial evidence does not adhere to the long-standing scientific principles required by the scientific community. For the kind of evidence that could be publicly confirmed is simply not the kind that survival researchers have been able to provide, just as we would expect of a hodgepodge of deception, embellishment, malobservation, misreporting, self-deception, and so on; but which would be surprising on the hypothesis that discarnate personal survival occurs. The survival evidence does not even survive elementary scrutiny, let alone outweigh our everyday experience of the biological fragility of our own minds. The totality of the evidence renders discarnate personal survival highly unlikely. Attempts to reinterpret this evidence away through various analogies fail because a hypothesis that makes false predictions, like that of the independence of individual consciousness from a functioning brain, will continue to make them no matter what analogy one uses to illustrate it. -/- 1.

This book promotes the research of present-day women working in ancient and medieval philosophy, with more than 60 women having contributed in some way to the volume in a fruitful collaboration. It contains 22 papers organized into ten distinct parts spanning the sixth century BCE to the fifteenth century CE. Each part has the same structure: it features, first, a paper which sets up the discussion, and then, one or two responses that open new perspectives and engage in further reflections. (...) Our authors’ contributions address pivotal moments and players in the history of philosophy: women philosophers in antiquity, Cleobulina of Rhodes, Plato, Lucretius, Bardaisan of Edessa, Alexander of Aphrodisias, Plotinus, Porphyry, Peter Abelard, Robert Kilwardby, William Ockham, John Buridan, and Isotta Nogarola. The result is a thought-provoking collection of papers that will be of interest to historians of philosophy from all horizons. Far from being an isolated effort, this book is a contribution to the ever-growing number of initiatives which endeavour to showcase the work of women in philosophy. (shrink)

I argue that there can be no such thing as a borderline case of the predicate ‘phenomenally conscious’: for any given creature at any given time, it cannot be vague whether that creature is phenomenally conscious at that time. I first defend the Positive Characterization Thesis, which says that for any borderline case of any predicate there is a positive characterization of that case that can show any sufficiently competent speaker what makes it a borderline case. I then appeal to (...) the familiar claim that zombies are conceivable, and I argue that this claim entails that there can be no positive characterizations of borderline cases of ‘phenomenally conscious’. By the Positive Characterization Thesis, it follows that ‘phenomenally conscious’ can not have any borderline cases. (shrink)

Bodily sensations, such as pain, hunger, itches, or sexual feelings, are commonly characterized in terms of their phenomenal character. In order to account for this phenomenal character, many philosophers adopt strong representationalism. According to this view, bodily sensations are essentially and entirely determined by an intentional content related to particular conditions of the body. For example, pain would be nothing more than the representation of actual or potential tissue damage. In order to motivate and justify their view, strong representationalists often (...) appeal to the reliable causal covariance between bodily sensations and certain kinds of bodily conditions or to the corresponding biological function that these bodily sensations are supposed to fulfill. In this paper, I argue on the basis of recent empirical research that arguments from reliable causal covariance and biological function cannot motivate the introduction of corresponding intentional content. In particular, I argue that bodily sensations are caused by a heterogeneous class of physiological and psychological factors and their biological functions are too diverse to be reduced to the representation of a particular bodily condition. Responses are available to strong representationalists, but they either require substantial alterations to their core assumptions or incur a significant empirical burden. (shrink)

Ordinary psychological predicates, and the phenomena we report to by means of them, can be grouped together into different categories. For instance, it is usual to group together phenomena such as belief and expectancy in a category of ‘propositional attitudes’, whereas sensations, like pain and itch, in a distinct one. Which taxonomy of the mental would be plausible to be adopted in contexts such as those of introductory books to the philosophy of mind, i.e., when we need to set out (...) only from minimal assumptions regarding these predicates and phenomena? This article suggests some desiderata and principles for such a taxonomy; exposes and critically assesses some taxonomies presented in introductory books to the philosophy of mind; and proposes the sketch of an alternative one.

Many philosophers hold one of two extreme views about our capacity to have phenomenally conscious experience : either that inner-sense enables us to know our experience and its properties infallibly or the contrary conviction that inner-sense is utterly fallible and the evidence it provides completely defeasible. Both of these are in error. This paper presents an alternative conception of inner-sense, modeled on disjunctive conceptions of perceptual awareness, that avoids both erroneous extremes, but that builds on the commonsense intuitions that motivate (...) them.

To be acquainted with something (in the philosophical sense of “acquainted” discussed here) is to be directly aware of it. The idea that we are acquainted with certain things we experience has been discussed throughout the history of Western Philosophy, but in the early 20th century it gained especially focused attention among analytic philosophers who drew their inspiration from Bertrand Russell's work on acquaintance. Since then, many philosophers—particularly those working on self‐knowledge or perception—have used the notion of acquaintance to explain (...) various facts about human experience and knowledge. In this paper, I offer an overview of this work, with particular focus on the resurgent literature on acquaintance in contemporary analytic philosophy. After more fully explaining what acquaintance is (or is supposed to be), I describe some reasons for thinking that we are indeed acquainted with certain things we experience, and then I survey some of the facts about experience and knowledge that acquaintance may help explain.

Peter Carruthers argues that the global workspace theory implies there are no facts of the matter about animal consciousness. The argument is easily extended to other cognitive theories of consciousness, posing a general problem for consciousness studies. But the argument proves too much, for it also implies that there are no facts of the matter about human consciousness. A key assumption of the argument is that scientific theories of consciousness must explain away the explanatory gap. I criticize this assumption and (...) point to an alternative strategy for defending scientific theories of consciousness, one that better reflects the ongoing scientific practice. I argue there are introspectable inferential connections from phenomenal concepts to functional concepts that scientists can use to individuate the global workspace in terms of capacities that animals and humans share.

Much of the philosophical work on perception has focused on vision. Recently, however, philosophers have begun to correct this ‘tunnel vision’ by considering other modalities. Nevertheless, relatively little has been written about the chemical senses—olfaction and gustation. The focus of this paper is olfaction. In this paper, I consider the question: does human olfactory experience represents objects as thus and so? If we take visual experience as the paradigm of how experience can achieve object representation, we might think that the (...) answer to this question is no. I argue that olfactory experience does indeed represent objects—just not in a way that is easily read from the dominant visual case. (shrink)

The philosophy of perception has been dominated by vision, with very little discussion of the chemical senses – olfaction and gustation. In this second entry of a pair on olfactory experience, I consider what olfaction has to tell us about two issues: the nature of perceptual objects and the nature of perceptual properties and, in particular, the secondary qualities. Given the scant work on olfaction in the philosophical literature, my discussion not only surveys what philosophers have said about olfaction so (...) far, but considers the most plausible views and/or most pressing questions in each area of inquiry.

Much of the philosophical work on perception has focused on vision. Recently, however, philosophers have been turning their attention to the ‘other modalities’. In a pair of entries, I consider olfaction—a sense modality that, along with gustation, has been largely overlooked by philosophers. In this first entry, I consider the challenge that olfactory experience presents to upholding a representational view of the sense modalities. It is common for philosophers to think that visual experience is world‐directed and, in particular, that it (...) is representational. World‐directed views contrast with subjectivist views—views according to which experiences are raw feels or mere sensations. Unlike visual experience, olfactory experience doesn't obviously support a representational view. Indeed, given its phenomenology, a subjectivist view of olfactory experience might seem unavoidable. But it is not. Once we begin to unravel ourselves from the dominant visual model of perception, we see that there is a representational view available that honors the phenomenology of olfactory experience. In turn, we learn that although there are some basic similarities between visual experience and olfactory experience, there are significant differences that prevent us from making easy generalizations from the visual case.

Seattle rain smelled different from New Orleans rain…. New Orleans rain smelled of sulfur and hibiscus, trumpet metal, thunder, and sweat. Seattle rain, the widespread rain of the Great Northwest, smelled of green ice and sumi ink, of geology and silence and minnow breath.— Tom Robbins, Jitterbug PerfumeMuch of the philosophical literature on perception has focused on vision. This is not surprising, given that vision holds for us a certain prestige. Our visual experience is incredibly rich, offering up a mosaic (...) of apparent three-dimensional objects. For this reason, it is commonplace to suppose that visual experience is world-directed, with the view taking its most popular form in the representational, or content, view. World-directed views contrast with what we might call subjectivist views — views according to which experiences are raw feels or mere sensations. (shrink)

Intuitively it has seemed to many that our concepts conscious state and conscious creature are sharp rather than vague, that they can have no borderline cases. On the other hand, many who take conscious states to be identical to, or realized by, complex physical states are committed to the vagueness of those concepts. In the paper I argue that conscious state and conscious creature are sharp by presenting four necessary conditions for conceiving borderline cases in general, and showing that some (...) of those conditions cannot be met with conscious state. I conclude that conscious state is sharp, and the conclusion is then extended to conscious creature. The paper ends with a brief discussion of some implications. (shrink)

This thesis brings together two concerns. The first is the nature of inference—what it is to infer—where inference is understood as a distinctive kind of conscious and self-conscious occurrence. The second concern is the possibility of doxastic agency. To be capable of doxastic agency is to be such that one is capable of directly exercising agency over one’s beliefs. It is to be capable of exercising agency over one’s beliefs in a way which does not amount to mere self-manipulation. Subjects (...) who can exercise doxastic agency can settle questions for themselves. A challenge to the possibility of doxastic agency stems from the fact that we cannot believe or come to believe “at will”, where this in turn seems to be so because belief “aims at truth”. It must be explained how we are capable of doxastic agency despite that we cannot believe or come to believe at will. On the orthodox ‘causalist’ conception of inference for an inference to occur is for one act of acceptance to cause another in some specifiable “right way”. This conception of inference prevents its advocates from adequately seeing how reasoning could be a means to exercise doxastic agency, as it is natural to think it is. Suppose, for instance, that one reasons and concludes by inferring where one’s inference yields belief in what one infers. Such an inference cannot be performed at will. We cannot infer at will when inference yields belief any more than we can believe or come to believe at will. When it comes to understanding the extent to which one could be exercising agency in such a case the causalist conception of inference suggests that we must look to the causal history of one’s concluding act of acceptance, the nature of the act’s being determined by the way in which it is caused. What results is a picture on which such reasoning as a whole cannot be action. We are at best capable of actions of a kind which lead causally to belief fixation through “mental ballistics”. The causalist account of inference, I argue, is in fact either inadequate or unmotivated. It either fails to accommodate the self-consciousness of inference or is not best placed to play the very explanatory role which it is put forward to play. On the alternative I develop when one infers one’s inference is the conscious event which is one’s act of accepting that which one is inferring. The act’s being an inference is determined, not by the way it is caused, but by the self-knowledge which it constitutively involves. This corrected understanding of inference renders the move from the challenge to the possibility of doxastic agency to the above ballistics picture no longer tempting. It also yields an account of how we are capable of exercising doxastic agency by reasoning despite being unable to believe or come to believe at will. In order to see how such reasoning could amount to the exercise of doxastic agency it needs to be conceived of appropriately. I suggest that paradigm reasoning which potentially amounts the exercise of doxastic agency ought to be conceived of as primarily epistemic agency—agency the aim of which is knowledge. With inference conceived as suggested, I argue, it can be seen how to engage in such reasoning can just be to successfully exercise such agency. (shrink)

We can learn much about perceptual experience by thinking about how it can mislead us. In this paper, I explore whether, and how, olfactory experience can mislead. I argue that, in the case of olfactory experience, the traditional distinction between illusion and hallucination does not apply. Integral to the traditional distinction is a notion of ‘object-failure’—the failure of an experience to present objects accurately. I argue that there are no such presented objects in olfactory experience. As a result, olfactory experience (...) can only mislead by means of a kind of property hallucination. The implications of my arguments are twofold. First, we see that accounts of representational content cannot always be based on the visual model. And, secondly, we see that we must recast the notion of nonveridicality, allowing for a notion of non-veridical experience that is disengaged from any particular object. (shrink)

According to pure imperativism, pain experiences are experiences of a specific phenomenal type that are entirely constituted by imperative content. As their primary argument, proponents of imperativism rely on the biological role that pain experiences fulfill, namely, the motivation of actions whose execution ensures the normal functioning of the body. In the paper, I investigate which specific types of action are of relevance for an imperative interpretation and how close their link to pain experiences actually is. I argue that, although (...) imperative theories constitute an apparently promising version of strong intentionalism, they cannot provide an imperative content that meets their own criteria of both sufficiency and necessity. I further argue that this issue cannot be solved by impure imperative theories either. (shrink)
