I defend a version of color subjectivism — that colors are sortals for certain neural events — by arguing against a sophisticated form of color objectivism and by showing how a subjectivist can legitimately explain the phenomenal fact that colors seem to be properties of external objects.

To attribute confusion to someone is to take up a paternalistic stance in evaluating his reasoning.

Everyone has mistaken one thing for another, such as a stranger for an acquaintance. A person who has mistaken two things, Joseph Camp argues, even on a massive scale, is still capable of logical thought. In order to make that idea precise, one needs a logic of confused thought that is blind to the distinction between the objects that have been confused. Confused thought and language cannot be characterized as true or false even though reasoning conducted in such language can (...) be classified as valid or invalid. To the extent that philosophers have addressed this issue at all, they take it for granted that confusion is a kind of ambiguity. Camp rejects this notion; his fundamental claim is that confusion is not a mental state. To attribute confusion to someone is to take up a paternalistic stance in evaluating his reasoning. Camp proposes a novel characterization of confusion, and then demonstrates its fruitfulness with several applications in the history of philosophy and the history of science. (shrink)

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.

A dual referent approach to colour theory maintains that colour names have two intended, equally legitimate referents. For example, one might argue that ‘red’ refers both to red appearances or qualia, and also to the way red objects reflect light, the spectral surface reflectance properties of red things. I argue that normal cases of perceptual relativity can be used to support a dual referent approach, yielding an understanding of colour whose natural extension includes abnormal cases of perceptual relativity. This contrasts (...) with Peacocke’s multi-referent view, according to which such abnormal cases force us to introduce a wholly distinct kind of colour experience. I also argue that the two uses of colour names, arising from their two referents, have different extensions, even in normal perceptual circumstances, a consequence which conflicts with the heart of Rosenthal’s dual referent view.

I defend indirect perceptual realism against two recent and related charges to it offered by A. D. Smith and P. Snowdon, both stemming from demonstrative reference involving indirect perception. The needed aspects of the theory of demonstratives are not terribly new, but their connection to these objections has not been discussed. The groundwork for my solution emerges from considering normal cases of indirect perception (e.g., seeing something depicted on a television) and examining the role this indirectness plays in demonstrative assertions. (...) I argue that indirectness routinely if not typically plays a justificatory role in such judgements, and not a semantic one, and that the same can be said of such judgements when considered within the indirect realist framework. The denial of this, on my analysis, is essential to the criticisms of Snowdon and Smith. The discussion is extended to include scenarios involving the sorts of misconceptions Smith employs. (shrink)

Should a principle of charity be applied to the interpretation of the colour concepts exercised in visual experience? We think not. We shall argue, for one thing, that the grounds for applying a principle of charity are lacking in the case of colour concepts. More importantly, we shall argue that attempts at giving the experience of colour a charitable interpretation either fail to respect obvious features of that experience or fail to interpret it charitably, after all. Charity to visual experience (...) is therefore no motive for resisting the natural, Galilean response to a scientific understanding of light and vision. The best interpretation of colour experience ends up convicting it of widespread and systematic error. (shrink)

This book is the one to put into the hands of those who have been over-impressed by Austin 's critics....[Warnock's] brilliant editing puts everybody who is concerned with philosophical problems in his debt.

In arithmetic, if only because many of its methods and concepts originated in India, it has been the tradition to reason less strictly than in geometry, ...

The Problem of Perception offers two arguments against direct realism--one concerning illusion, and one concerning hallucination--that no current theory of ...

In this highly original monograph, Nicholas Georgalis proposes that the concept of minimal content is fundamental both to the philosophy of mind and to the philosophy of language. He argues that to understand mind and language requires minimal content -- a narrow, first-person, non-phenomenal concept that represents the subject of an agent's intentional state as the agent conceives it. Orthodox third-person objective methodology must be supplemented with first-person subjective methodology. Georgalis demonstrates limitations of a strictly third-person methodology in the study (...) of mind and language and argues that these deficiencies can be corrected only by the incorporation of a first-person methodology. Nevertheless, this expanded methodology makes possible an objective understanding of the subjective. Georgalis argues against the conflation of consciousness and subjectivity with phenomenal experience. Consequently, and contrary to common belief, he argues that consciousness without phenomenality is as strongly implicated in intentionality as it is in phenomenal states. He proposes a broader understanding of the "hard problem" of consciousness, arguing that there is an "explanatory gap problem" for both phenomenal and intentional states. His theory provides a framework that renders the vexing relations between mental and brain states comprehensible. Georgalis also argues for novel explanations of the phenomenal and of representation -- explanations that follow from the core concept of minimal content. Treating the topics of meaning and reference, he introduces a first-person concept of intended reference derivative from minimal content that resolves various problems in the philosophy of language. Eschewing ontology, Georgalis proposes his theory as a means to make sense of, analyze, and relate issues in the philosophies of mind and language. The concept of minimal content, he argues, plays a necessary, pivotal, unifying, and foundational role in advancing our understanding of these issues. (shrink)

red and round. According to common sense, the red, round thing we see is the tomato itself. When we have a hallucinatory vision of a tomato, however, there may be present to us no red and round phys- ical object. Still, we use the words 'red' and 'round' to describe that situation as well, this time applying them to the visual experience itself. We say that we have a red, round visual image, or a visual experience of a red disk, (...) or some such. Because we see physical objects far more often than we hallucinate, we apply terms for color and shape to physical objects far more often than to visual experiences. Moreover, different theories of perception explain in different ways the applications such terms have to physical objects and to visual experiences. But whatever their frequency and explanation, it seems clear that both sorts of application occur. (shrink)

Siegel defends "Limited Intentionism", a theory of what secures the semantic reference of uses of bare demonstratives ("this", "that" and their plurals). According to Limited Intentionism, demonstrative reference is fixed by perceptually anchored intentions on the part of the speaker.
