You know what someone else is thinking and feeling by observing them. But how do you know what you are thinking and feeling? This is the problem of self-knowledge: Alex Byrne tries to solve it. The idea is that you know this not by taking a special kind of look at your own mind, but by an inference from a premise about your environment.

Are women (simply) adult human females? Dictionaries suggest that they are. However, philosophers who have explicitly considered the question invariably answer no. This paper argues that they are wrong. The orthodox view is that the category *woman* is a social category, like the categories *widow* and *police officer*, although exactly what this social category consists in is a matter of considerable disagreement. In any event, orthodoxy has it that *woman* is definitely not a biological category, like the categories *amphibian* or (...) *adult human female*. In the first part, a number of arguments are given for the view that women are adult human females; the second part turns to rebutting the main objections. Finally, a couple of morals are briefly noted: one for activist sloganeering, and one for ameliorative projects that seek to change the meaning of ‘woman’. (shrink)

Traditionally, perceptual experiences—for example, the experience of seeing a cat—were thought to have two quite distinct components. When one sees a cat, one’s experience is “about” the cat: this is the representational or intentional component of the experience. One’s experience also has phenomenal character: this is the sensational component of the experience. Although the intentional and sensational components at least typically go together, in principle they might come apart: the intentional component could be present without the sensational component or vice (...) versa.

The target article is an attempt to make some progress on the problem of color realism. Are objects colored? And what is the nature of the color properties? We defend the view that physical objects (for instance, tomatoes, radishes, and rubies) are colored, and that colors are physical properties, specifically types of reflectance. This is probably a minority opinion, at least among color scientists. Textbooks frequently claim that physical objects are not colored, and that the colors are "subjective" or "in (...) the mind." The article has two other purposes: first, to introduce an interdisciplinary audience to some distinctively philosophical tools that are useful in tackling the problem of color realism and, second, to clarify the various positions and central arguments in the debate.

The 'content view', in slogan form, is 'Perceptual experiences have representational content'. I explain why the content view should be reformulated to remove any reference to 'experiences'. I then argue, against Bill Brewer, Charles Travis and others, that the content view is true. One corollary of the discussion is that the content of perception is relatively thin (confined, in the visual case, to roughly the output of 'mid-level' vision). Finally, I argue (briefly) that the opponents of the content view are (...) partially vindicated, because perceptual error is due to false belief. (shrink)

When one visually hallucinates, the object of one’s hallucination is not before one’s eyes. On the standard view, that is because the object of hallucination does not exist, and so is not anywhere. Many different defenses of the standard view are on offer; each have problems. This paper defends the view that there is always an object of hallucination—a physical object, sometimes with spatiotemporally scattered parts.

Siegel and Byrne debate whether perceptual experiences present rich properties or exclusively thin properties.

This paper elaborates and defends a familiar ‘transparent’ account of knowledge of one's own beliefs, inspired by some remarks of Gareth Evans, and makes a case that the account can be extended to mental states in general, in particular to knowledge of one's intentions.

Perceptual experiences justify beliefs—that much seems obvious. As Brewer puts it, “sense experiential states provide reasons for empirical beliefs” (this volume, xx). In Mind and World McDowell argues that we can get from this apparent platitude to the controversial claim that perceptual experiences have conceptual content: [W]e can coherently credit experiences with rational relations to judgement and belief, but only if we take it that spontaneity is already implicated in receptivity; that is, only if we take it that experiences have (...) conceptual content. (1994, 162) Brewer agrees. Their view is sometimes called conceptualism; nonconceptualism is the rival position, that experiences have nonconceptual content. One initial obstacle is understanding what the issue is. What is conceptual content, and how is it different from nonconceptual content? Section 1 of this paper explains two versions of each of the rival positions: state (non)conceptualism and content (non)conceptualism; the latter pair is the locus of the relevant dispute. Two prominent arguments for content nonconceptualism—the richness argument and the continuity argument—both fail (section 2). McDowell’s and Brewer’s epistemological defenses of content conceptualism are also faulty (section 3). Section 4 gives a more simple-minded case for conceptualism; finally, some reasons are given for rejecting the claim—on one natural interpretation—that experiences justify beliefs. (shrink)

I know various contingent truths about my environment by perception. For example, by looking, I know that there is a computer before me; by hearing, I know that someone is talking in the corridor; by tasting, I know that the coffee has no sugar. I know these things because I have some built-in mechanisms specialized for detecting the state of my environment. One of these mechanisms, for instance, is presently transducing electromagnetic radiation (in a narrow band of wavelengths) coming from (...) the computer and the desk on which it sits. How that mechanism works is a complicated story—to put it mildly—and of course much remains unknown. But we can at least produce more-or- less plausible sketches of how the mechanism can start from retinal irradiation, and go on to deliver knowledge of my surroundings. Moreover, in the sort of world we inhabit, specialized detection mechanisms that are causally affected by the things they detect have no serious competition—seeing the computer by seeing an idea of the computer in the divine mind, for example, is not a feasible alternative.

The “affirming” healthcare model for gender-distressed youth is endorsed by the medical establishment in the United States, but many European nations have retreated from it. This controversy would be expected to attract the interest of philosophers and bioethicists, with a diverse range of opinions appearing in academic articles. However, when philosophers and bioethicists have ventured into print, they have almost invariably endorsed the affirmative approach, which involves life-changing medical interventions on children with psychological problems. This is a sign that the (...) process of academic research and writing is not functioning as it should. We recount the failure of philosophy and bioethics to address the issues raised by gender-affirming healthcare. We also offer an explanation of this failure, and in the final section make some recommendations for improving academic integrity. (shrink)

Sex used to rule. Now gender identity is on the throne. Sex survives as a cheap imitation of its former self: assigned at birth, on a spectrum, socially constructed, and definitely not binary. Apparently quite a few of us fall outside the categories ‘male’ and ‘female’. But gender identity is said to be universal – we all have one. Humanity used to be cleaved into two sexes, whereas now the crucial division depends on whether our gender identity aligns with our (...) body. If it does, we are cisgender; if it does not, we are transgender. The dethroning of sex has meant the threat of execution for formerly noble words such as ‘woman’ and ‘man’. In this provocative, bold, and humane book, the philosopher Alex Byrne pushes back against the new gender revolution. Drawing on evidence from biology, psychology, anthropology and sexology, Byrne exposes the flaws in the revolutionary manifesto. The book applies the tools of philosophy, accessibly and with flair, to gender, sex, transsexuality, patriarchy, our many identities, and our true or authentic selves. The topics of _Trouble with Gender_ are relevant to us all. This is a book for anyone who has wondered ‘Is sex binary?’, ‘Why are men and women different?’, ‘What is a woman?’ or, simply, ‘Where can I go to know more about these controversies?’ Revolutions devour their own children, and the gender revolution is no exception. _Trouble with Gender_ joins the forefront of the counter-revolution, restoring sex to its rightful place, at the centre of what it means to be human.

According to orthodoxy, perceptual beliefs are caused by perceptual experiences. The paper argues that this view makes it impossible to explain how experiences can be epistemically significant. A rival account, on which experiences in the “good case” are ways of knowing, is set out and defended.

Remembering a cat sleeping (specifically, recollecting the way the cat looked), perceiving (specifically, seeing) a cat sleeping, and imagining (specifically, visualizing) a cat sleeping are of course importantly different. Nonetheless, from the first-person perspective they are palpably alike. The paper addresses two questions: Q1. What are these similarities (and differences)? Q2. How does one tell that one is recalling (and so not perceiving or imagining)?

This essay surveys the varieties of disjunctivism about perceptual experience. Disjunctivism comes in two main flavours, metaphysical and epistemological.

Consciousness is the subject of many metaphors, and one of the most hardy perennials compares consciousness to a spotlight, illuminating certain mental goings-on, while leaving others to do their work in the dark. One way of elaborating the spotlight metaphor is this: mental events are loaded on to one end of a conveyer belt by the senses, and move with the belt.

Richard Heck, in "The Sense of Communication" (Mind, 104, pp. 79-106, 1995), argues against the "Hybrid View"--the claim, roughly, that names are Millian while beliefs are Fregean. We argue that Heck's argument fails.

This much-anticipated book is a detailed elaboration and defense of Levine’s influential claim that there is an “explanatory gap” between the mental and the physical.

How do I know that I see a cat? A curiously under-asked question. The paper tries to answer it.

When we open our eyes, the world seems full of colored opaque objects, light sources, and transparent volumes. One historically popular view, _eliminativism_, is that the world is not in this respect as it appears to be: nothing has any color. Color _realism_, the denial of eliminativism, comes in three mutually exclusive varieties, which may be taken to exhaust the space of plausible realist theories. Acccording to _dispositionalism_, colors are _psychological_ dispositions: dispositions to produce certain kinds of visual experiences. According (...) to both _primitivism_ and _physicalism_, colors are not psychological dispositions; they differ in that primitivism says that no reductive analysis of the colors is possible, whereas physicalism says that they are physical properties. This paper is a defense of physicalism about color. (shrink)

Qualia internalism is the thesis that qualia are intrinsic to their subjects: the experiences of intrinsic duplicates have the same qualia. Content externalism is the thesis that mental representation is an extrinsic matter, partly depending on what happens outside the head. 1 Intentionalism comes in strong and weak forms. In its weakest formulation, it is the thesis that representationally identical experiences of subjects have the same qualia. 2.

Classic texts that define the disjunctivist theory of perception.

The typical kind of color realism is reductive: the color properties are identified with properties specified in other terms (as ways of altering light, for instance). If no reductive analysis is available — if the colors are primitive sui generis properties — this is often taken to be a convincing argument for eliminativism. That is, realist primitivism is usually thought to be untenable. The realist preference for reductive theories of color over the last few decades is particularly striking in light (...) of the generally anti-reductionist mood of recent philosophy of mind. The parallels between the mind—body problem and the case of color are substantial enough that the difference in trajectory is surprising. While dualism and non-reductive physicalism are staples, realist primitivism is by and large a recent addition to the color literature. And it remains a minority position, although one that is perhaps gaining support. In this paper, we investigate whether it should be accepted, and conclude it should not be. (shrink)

Anything is similar to anything, provided the respects of similarity are allowed to be gerrymandered or gruesome, as Goodman observed.2 But similarity in non-gruesome or—as I shall say—genuine respects is much less ecumenical. Colors, it seems, provide a compelling illustration of the distinction as applied to similarities among properties.3 For instance, in innumerable gruesome respects, blue is more similar to yellow than to purple. But in a genuine respect, blue is more similar to purple than to yellow (genuinely more similar, (...) as I shall sometimes put it). (shrink)

How do you know what you want? The question is neglected by epistemologists. This paper attempts an answer.

Dembroff’s “Escaping the natural attitude about gender” replies to my “Are women adult human females?”. This paper responds to Dembroff’s many criticisms of my arguments, as well as to the charge that “Are women...” “fundamentally is an unscholarly attempt to vindicate a political slogan that is currently being used to undermine civic rights and respect for trans persons”. I argue that Dembroff’s criticisms fail without exception, and explain why the claims about my motives are baseless.

Soc. …I speak of what I scarcely understand; but the soul when thinking appears to me to be just talking—asking questions of herself and answering them, affirming and denying. And when she has arrived at a decision, either gradually or by a sudden impulse, and has at last agreed, and does not doubt, this is called her opinion. I say, then, that to form an opinion is to speak, and opinion is a word spoken,—I mean, to oneself and in silence, (...) not aloud or to another: What think you? Theaet. I agree. (shrink)

This chapter surveys the varieties of disjunctivism concerning perceptual experience. Disjunctivism comes in two main flavours: metaphysical and epistemological. Metaphysical disjunctivism is the view usually associated with the disjunctivist label. After some initial discussion of (metaphysical) disjunctivism, epistemological disjunctivism is explained. The rest of the chapter is solely concerned with explaining and assessing metaphysical disjunctivism, a theory of the nature of perceptual experience. The main conclusion is that although there is considerable insight in the vicinity, metaphysical disjunctivism is false.

Different authors offer subtly different characterizations of naïve realism. We disentangle the main ones and argue that illusions provide the best proving ground for naïve realism and its main rival, representationalism. According to naïve realism, illusions never involve perceptual error. We assess two leading attempts to explain apparent perceptual error away, from William Fish and Bill Brewer, and conclude that they fail. Another leading attempt is assessed in a companion paper, which also sketches an alternative representational account.

Continuing correspondence on 'gender identity'.

A defense of the biological view of gender—that women are adult human females, boys are juvenile human males, etc. Written for undergraduates, and paired with a rival piece by Lenny Clapp and Laura Girola.

The transgender child is a familiar and polarizing trope in the present century. Some, such as the writer J. K. Rowling, take transgender children to be cultural fictions: there are no trans kids, as there are no mermaids or leprechauns. Others, including prominent figures in pediatric gender medicine, hold that some children are transgender, just as some children have brown eyes or are naturally outgoing. The only difference is that transgender children require special support, unlike brown-eyed or outgoing children. Instruction (...) manuals are needed, for instance Brill and Pepper’s The Transgender Child: A Handbook for Parents and Professionals. And when puberty commences, medical interventions may be recommended. A third view is that transgender children are examples of “making up people” in the sense of Ian Hacking’s eponymous 1986 essay: transgender children are brought into existence by a social process that involves (in part) naming or classifying children as transgender. This paper defends the third view: there are trans kids, but they are made, not discovered. (shrink)

The sceptic about the external world presents us with a paradox: an apparently acceptable argument for an apparently unacceptable conclusion—that we do not know anything about the external world. Some paradoxes, for instance the liar and the sorites, are very hard. The defense of a purported solution to either of these two inevitably deploys the latest in high-tech philosophical weaponry. On the other hand, some paradoxes are not at all hard, and may be resolved without much fuss. They do not (...) contain profound lessons about the human condition. Where should we place the sceptical paradoxes? (shrink)

Over the last century, biologists have come to know much more about the two sexes, but they have not seen any need to revise the traditional binary “gametic” account of sex. One would expect that medical controversies would take place against a background of agreement on the sex binary. Recent cultural trends have dashed that expectation. What changed was not science, but politics: the new century’s push for transgender rights sowed doubts about the sex binary, making sex-classification in law, education, (...) sport, and medicine highly controversial. This article explores the manifestation of these cultural trends in academia and medicine, which has been to the detriment of medical standards and the well-being of patients. An instructive case study is the area of medicine in which the hegemony of non-binarism has been most dramatic: the treatment of people—including minors—suffering from gender distress. (shrink)

Critical discussion of Susanna Schellenberg's account of hallucination and perceptual evidence.

A Letter to the Editor about the origin of "gender identity" and deficiencies in its current definition.

Dispositional theories of colour have been attacked by McGinn and others on the ground that ‘Colours do not look like dispositions’. Langsam has argued that on the contrary they do, in ‘Why Colours Do Look Like Dispositions’, The Philosophical Quarterly, 50, pp. 68–75. I make three claims. First, neither side has made its case. Secondly, it is true, at least on one interpretation, that colours do not look like dispositions. Thirdly, this does not show that dispositionalism about colours is false.

In the writings of Daniel Dennett and Donald Davidson we find something like the following bold conjecture: it is an a priori truth that there is no gap between our best judgements of a subject's beliefs and desires and the truth about the subject's beliefs and desires. Under ideal conditions a subject's belief-box and desire-box become transparent.
