A survey of color science and color vision.

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

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

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

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

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)

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

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.

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.

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.

One very popular framework in contemporary epistemology is Bayesian. The central epistemic state is subjective confidence, or credence. Traditional epistemic states like belief and knowledge tend to be sidelined, or even dispensed with entirely. Credences are often introduced as familiar mental states, merely in need of a special label for the purposes of epistemology. But whether they are implicitly recognized by the folk or posits of a sophisticated scientific psychology, they do not appear to fit well with perception, as is (...) often noted. -/- This paper investigates the tension between probabilistic cognition and non-probabilistic perception. The tension is real, and the solution—to adapt a phrase from Quine and Goodman—is to renounce credences altogether. (shrink)

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)?

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

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

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.

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.

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.

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.

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.

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

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.

Continuing correspondence on 'gender identity'.

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.

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.

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.

Comment on Declan Smithies's book The Epistemic Role of Consciousness (2019).

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.

Millar has written a valuable monograph on perceptual knowledge. Knowing By Perceiving is careful and detailed, at times laborious, delivering many insights. Oc.

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.

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

“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)

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)

Response-dependence theories have historically been very popular in aesthetics, and aesthetic response-dependence has motivated response-dependence in ethics. This chapter closely examines the prospects for such theories. It breaks this category down into dispositional and fittingness strands of response-dependence, corresponding to descriptive and normative ideal observer theories. It argues that the latter have advantages over the former but are not themselves without issue. Special attention is paid to the relationship between hedonism and response-dependence. The chapter also introduces two aesthetic properties that (...) lead to wrong kinds of reasons problems for aesthetic response-dependence: insightfulness and the capacity to change one’s perspective. These properties do not have obvious parallels in the ethical domain, and so present an obstacle for response-dependence even in aesthetics. The chapter ends by examining replies on behalf of the response-dependence theorist, ultimately suggesting that a restricted form of response-dependence is the most promising way forward for fans of such theories.

There are at least two different aspects of our rational evaluation of agents’ doxastic attitudes. First, we evaluate these attitudes according to whether they are supported by one’s evidence (substantive rationality). Second, we evaluate these attitudes according to how well they cohere with one another (structural rationality). In previous work, I’ve argued that substantive and structural rationality really are distinct, sui generis, kinds of rationality – call this view ‘dualism’, as opposed to ‘monism’, about rationality – by arguing that the (...) requirements of substantive and structural rationality can come into conflict. In this paper, I push the dialectic on this issue forward in two main ways. First, I argue that the most promising ways of resisting the diagnosis of my cases as conflicts still end up undermining monism in different ways. Second, supposing for the sake of argument that we should understand the cases as conflicts, I address the question of what we should do when such conflicts arise. I argue that, at least in a prominent kind of conflict case, the coherence requirements take precedence over the evidential requirements. (shrink)

Much of the debate about Aristotle’s criticisms of Plato has focused on the separability of the Forms. Here the dispute has to do with the ontological status of the Forms, in particular Plato’s claim for their ontological priority in relation to perceptible objects. Aristotle, however, also disputes the explanatory and causal roles that Plato claims for the Forms. This second criticism is independent of the first; even if the problem of the ontological status of the Forms were resolved to Aristotle’s (...) satisfaction, this second criticism would still stand. The problem here is not that there is no room for Aristotle’s four causes in Plato’s ontology; on the contrary, antecedents for all four can be found in Plato’s works. The problem, instead, is that Plato’s Forms fail to meet the general requirements that Aristotle sets out for the material, efficient, formal, and final causes of perceptible objects. Hence, even if the Forms were immanent in perceptible objects, they would still explain nothing about them. (shrink)

This chapter is centered around an apparent tension that research on implicit bias raises between virtue and social knowledge. Research suggests that simply knowing what the prevalent stereotypes are leads individuals to act in prejudiced ways—biasing decisions about whom to trust and whom to ignore, whom to promote and whom to imprison—even if they reflectively reject those stereotypes. Because efforts to combat discrimination obviously depend on knowledge of stereotypes, a question arises about what to do next. This chapter argues that (...) the obstacle to virtue is not knowledge of stereotypes as such, but the “accessibility” of such knowledge to the agent who has it. “Accessibility” refers to how easily knowledge comes to mind. Social agents can acquire the requisite knowledge of stereotypes while resisting their pernicious influence, so long as that knowledge remains, in relevant contexts, relatively inaccessible.

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.

Context-sensitive expressions appear ill suited to the purpose of sharing content across contexts. Yet we regularly use them to that end (in regulations, textbooks, memos, guidelines, laws, minutes, etc.). This paper describes the utility of the concept of a metacontext for understanding cross-contextual content-sharing with context-sensitive expressions. A metacontext is the context of a group of contexts: an infrastructure that can channel non-linguistic incentives on content ascription so as to homogenize the content ascribed to context-sensitive expressions in each context in (...) the group. Documents composed of context-sensitive expressions can share content across contexts when supported by an appropriate metacontext. The bible has its church, the textbook its education system, the form its bureaucracy, and the manifesto its social movement. Some metacontexts support cross-contextual content-sharing. Some don’t. A promising research programme (one with practical importance) would take metacontexts as its unit of analysis. (shrink)

What can we do—and what should we do—to fight against bias? This final chapter introduces empirically-tested interventions for combating implicit (and explicit) bias and promoting a fairer world, from small daily-life debiasing tricks to larger structural interventions. Along the way, this chapter raises a range of moral, political, and strategic questions about these interventions. This chapter further stresses the importance of admitting that we don’t have all the answers. We should be humble about how much we still don’t know and (...) dedicate efforts to gathering as much knowledge as possible. Even so, we know enough now to start making a difference, and this chapter ultimately aims to chip away at the gap between our abstract commitments to treat people fairly and our lived habits and experiences, which continue to be shaped by implicit and explicit prejudices and stereotypes about race, gender, and other social categories.

There is a correlation between positions taken on some scientific questions and political leaning. One way to explain this correlation is the cultural cognition hypothesis (CCH): people's political leanings are causing them to process evidence to maintain fixed answers to the questions, rather than to seek the truth. Another way is the different background belief hypothesis (DBBH): people of different political leanings have different background beliefs which rationalize different positions on these scientific questions. In this article, I argue for two (...) things. I argue that two attempts by proponents of the CCH to discredit the DBBH fail. And I argue that this matters, because while the CCH makes epistemic paternalistic interventions seem called for (as some philosophers have argued compellingly), the DBBH does not. The DBBH makes it much easier to stay closer to an ideal of deliberative democracy. (shrink)
