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)

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.

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)

Comment on Brogaard's Seeing and Saying (OUP 2018).

In a companion paper (Byrne and Green 2023) we disentangled the main characterizations of naïve realism and argued 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 assessed two leading attempts to explain apparent perceptual error away, from William Fish and Bill Brewer, and concluded that they fail. This paper considers another prominent attempt, from Craig French and Ian Phillips, and also sketches the (...) case for representationalism. (shrink)

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

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 per- ceptual error. We assess two leading attempts to explain apparent perceptual error away, from William Fish and Bill Brewer, and conclude that they fail. Another lead- ing attempt is assessed in a companion paper, which also sketches an alternative representational account.

At least in one well-motivated sense of ‘concept’, all perception involves concepts, even perception as practiced by lizards and bees. That is because—the paper argues—all perception involves belief.

The Unity of Perception offers a grand synoptic vision of how perception, consciousness and knowledge fit together. It is a remarkable achievement. A short comment can only address fragments of Schellenberg’s picture; naturally I will look for weak spots.

In clinical studies, childhood-onset gender dysphoria does not usually persist through puberty, at least if the child has not socially transitioned. If dysphoria persists into puberty, is it unlikely to abate without medical intervention? Many clinicians would give an affirmative answer. Gender dysphoria after puberty is often said to be "highly persistent.” The article examines whether this opinion is backed by good evidence, and concludes that it isn't.

The paper argues -- against the standard view in metaphysics -- that the existence of ordinary objects like tomatoes is (near-enough) established by the fact that such things are apparently encountered in perception.

A survey of arguments for and against the view that colors are physical properties.

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

This comment mainly examines Yli-Vakkuri and Hawthorne’s preferred framework for examining whether narrow content is viable, arguing that their framework is not well-suited to the task; once a more traditional framework is adopted, Y&H’s case against internalism is strengthened.

A survey of color science and color vision.

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.

Continuing correspondence on 'gender identity'.

In recent years, pronouns have become a white-hot interface between language and social and political issues. “My pronouns are he/they” signals allegiance to one side in the culture wars, as does “My pronouns are whatever.” But there is surprisingly little philosophical work at this interface; this paper aims to chart the main questions and argue for some answers, with the hope of stimulating more research.

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)?

David Rosenthal couples his higher-order thought theory of consciousness with a theory of “mental qualities”, properties of mental states. The first thesis of this paper is that there are no mental qualities as Rosenthal conceives of them. The second thesis is that Rosenthal’s residual insights are significant. They naturally lead to a simple first-order theory of consciousness.

This paper critically examines color relationalism and color relativism, two theories of color that are allegedly supported by variation in normal human color vision. We mostly discuss color relationalism, defended at length in Jonathan Cohen's The Red and the Real, and argue that the theory has insuperable problems.

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. (shrink)

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.

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

On the assumption that we may learn from our elders and betters, this paper approaches some fundamental questions in perceptual epistemology through a dispute between McDowell and Wright about external world scepticism.

Philosophers of mind have distinguished (and sometimes conflated) various qualities. This article tries to sort things out.

Skepticism about the internal world is actually more troubling than skepticism about the external world.

Review of Perception and Its Objects (OUP 2011), by Bill Brewer.

Critical discussion of Chris Hill's perceptual theory of pain.

Color-vision defects constitute a spectrum of disorders with varying degrees and types of departure from normal human color vision. One form of color-vision defect is dichromacy; by mixing together only two lights, the dichromat can match any light, unlike normal trichromatic humans, who need to mix three. In a philosophical context, our titular question may be taken in two ways. First, it can be taken at face value as a question about visible properties of external objects, and second, it may (...) be interpreted as the more intangible question of “what it’s like” to be color-blind.

Hill's views on visual experience are critically examined.

“Avowals” are utterances that “ascribe [current] states of mind”; for instance utterances of ‘I have a terrible headache’ and ‘I’m finding this painting utterly puzzling’ (Bar-On 2004: 1). And avowals, “when compared to ordinary empirical reports…appear to enjoy distinctive security” (1), which Bar-On elaborates as follows: A subject who avows being tired, or scared of something, or thinking that p, is normally presumed to have the last word on the relevant matters; we would not presume to criticize her self-ascription or (...) to reject it on the basis of our contrary judgement. Furthermore, unlike ordinary empirical reports, and somewhat like apriori statements, avowals are issued with a very high degree of confidence and are not easily subjected to doubt. (3) The project of this ambitious, original, and challenging book is to explain why avowals have this distinctive security. Bar-On’s guiding idea is that avowals “can be seen as pieces of expressive behavior, similar in certain ways to bits of behavior that naturally express subjects’ states” (227). Crying and moaning are natural expressions of pain, yawning is a natural expression of tiredness, reaching for beer is a natural expression of the desire for beer, and so on. In some important sense, avowals are supposed to be like that. In what sense, though? It will be useful to begin with the simplest answer. (shrink)

I am grateful to Mike Martin, Alex Byrne, and Niko Orlandi for the extraordinary care they have taken with my book Seeing and Saying (Oxford University Press, 2018) and for their incisive and challenging comments and criticisms. I regret that, for lack of space, I can only respond to what I take to be their main points of criticism. The order of my replies is alphabetical.

In his essay ‘Transparency, Belief, Intention’, Alex Byrne (2011) argues that transparency—our ability to form beliefs about some of our intentional mental states by considering their subject matter, rather than on the basis of special psychological evidence—involves inferring ‘from world to mind’. In this reply I argue that this cannot be correct. I articulate an intuitive necessary condition for a pattern of belief to count as a rule of inference, and I show that the pattern involved in transparency (...) does not meet that condition. As a result, I conclude that transparency does not involve inference. (shrink)

This is a letter from an amateur philosopher to Alex Byrne expressing perplexity on reading Byrne's chapter in The Oxford Handbook of the Philosophy of Mind, "Sensory Qualities, Sensible Qualities, Sensational Qualities" (2009). A version of the theory of indirect perception is described using several analogies and one autobiographical episode. It is described as a realization that occurred historically and may occur to individuals, supplanting default naive realism. Byrne's readings of various philosophers' accounts of sensory qualities (...) are then contrasted with an interpretation consistent with the adduced theory of indirect perception. The difficulty of imagining the view from the opposite side of the direct/indirect perception divide is remarked upon. (shrink)

This is a review of Transparency and Self-Knowledge, by Alex Byrne, Oxford University Press, Oxford, UK, 2018, xi+227 pp., £46.61 (Hardback), ISBN 9780198821618.

Alex Byrne and Jordi Fernández propose two different versions of a transparency theory of self-knowledge. According to Byrne, we self-attribute beliefs by an inference from what we take to be facts about the world (following a rule he calls BEL). According to Fernández, we self-attribute the belief that p on the basis of a prior mental state, a state which constitutes our grounds for the belief that p (thereby realizing a procedure he calls Bypass). In this paper, (...) I present the two theories in outline and discuss various objections concerning their normative (Can the procedure give us knowledge?) and metaphysical aspects (Is the procedure functional?). I conclude that especially the metaphysical objections against Bypass are somewhat more difficult to counter than those against BEL and that the modifications required of Fernández’s theory make it very similar to Byrne’s. -/- Alex Byrne y Jordi Fernández proponen dos diferentes versiones de la teoría de la transparencia del autoconocimiento. Según Byrne, para autoatribuir creencias inferimos qué es lo que creemos a partir lo que tomamos como hechos sobre el mundo (siguiendo una regla que Byrne llama BEL). Según Fernández, autoatribuimos la creencia de que p con base en un estado anterior a esta creencia, un estado que fundamenta la creencia de que p (realizando un procedimiento que él llama Bypass). En este artículo expongo las dos teorías y discuto objeciones que conciernen su aspecto normativo (¿puede el procedimiento darnos conocimiento?) y metafísico (¿es funcional el procedimiento?). Concluyo que en especial las objeciones metafísicas son más graves en el caso de Bypass que en el de BEL y que las modificaciones requeridas de la teoría de Fernández la asemejan mucho a la de Byrne.
