What is the relationship between color experience and color? Here, I defend the view that it is semantic: color experience denotes color in a code innately known by the perceiver. This semantic theory contrasts with a variety of theories according to which color is defined as the cause of color experience (in a special set of circumstances). It also contrasts with primary quality theories of color, which treat color as a physical quantity. I argue that the semantic theory better accounts for the kinds of knowledge we have regarding both the color of objects that we see and of the colors themselves.

Reid offers an under-appreciated account of the primary/secondary quality distinction. He gives sound reasons for rejecting the views of Locke, Boyle, Galileo and others, and presents a better alternative, according to which the distinction is epistemic rather than metaphysical. Primary qualities, for Reid, are qualities whose intrinsic natures can be known through sensation. Secondary qualities, on the other hand, are unknown causes of sensations. Some may object that Reid's view is internally inconsistent, or unacceptably relativistic. However, a deeper understanding shows that it is consistent, and relative only to normal humans. To acquire this deeper understanding, one must also explore the nature of dispositions, Reid's rejection of the theory of ideas, his distinction between sensation and perception, and his distinction between natural and acquired perceptions.

The Dangerous Book for Boys Abstract: Seventeenth and eighteenth century discussions of the senses are often thought to contain a profound truth: some perceptible properties are secondary qualities, dispositions to produce certain sorts of experiences in perceivers. In particular, colors are secondary qualities: for example, an object is green iff it is disposed to look green to standard perceivers in standard conditions. After rebutting Boghossian and Velleman’s argument that a certain kind of secondary quality theory is viciously circular, we discuss three main lines of argument for the secondary quality theory. The first is inspired by an intuitively compelling picture of perception articulated by Reid; the second is that the secondary quality theory is a conceptual truth; the third line of argument is presented in Johnston’s influential paper ‘How to speak of the colors’. We conclude that all these arguments fail, and that the secondary quality theory is unmotivated. Keywords: color, secondary quality, disposition, vision, perception..

This article presents an overview of the current debate on Kant's doctrine of idealism, focussing on the metaphysical interpretations of Ameriks, Allais, Friebe, Langton, Van Cleve and Westphal, and also on Guyer's recent reassessment of Allison's latest views.

References to Kant's so-called Copernicanism or Copernican turn are often put in very general terms. It is commonly thought that Kant makes the Copernican analogy solely in order to point out the fact as such of a paradigm shift in philosophy. This is too historical an interpretation of the analogy. It leaves unexplained both Kant's and Copernicus' reasons for advancing their respective hypotheses, which brought about major changes in the conceptual schemes of philosophy and astronomy. My contention is that something much more specific, systematic is at issue, which contrary to received understanding makes Kant's analogy in fact particularly apt.

This paper compares Kant's transcendental idealism with three main groups of contemporary anti-realism, associated with Wittgenstein, Putnam, and Dummett, respectively. The kind of anti-realism associated with Wittgenstein has it that there is no deep sense in which our concepts are answerable to reality. Associated with Putnam is the rejection of four main ideas: theoryindependent reality, the idea of a uniquely true theory, a correspondence theory of truth, and bivalence. While there are superficial similarities between both views and Kant's, I find more significant differences. Dummettian anti-realism, too, clearly differs from Kant's position: Kant believes in verification-transcendent reality, and transcendental idealism is not a theory of meaning or truth. However, I argue that part of the Dummettian position is extremely useful for understanding part of Kant's position - his idealism about the appearances of things. I argue that Kant's idealism about appearances can be expressed as the rejection of experiencetranscendent reality with respect to appearances.

In what follows I will address Kant’s concerns in the First Analogy and in the Refutation of Idealism. Because the two discussions have a similar trajectory, it is of interest to identify some of the differences between them. As we will see, the manifest differences are indicative of more significant underlying differences, regarding two ways of construing transcendental proofs.

The role of analogy appears in surprisingly different areas of the first Critique. On the one hand, Kant considered the concept to have a specific enough meaning to entitle the principle concerned with causation an analogy; on the other hand we can find Kant referring to analogy in various parts of the Transcendental Dialectic in a seemingly different manner. Whereas in the Transcendental Analytic, Kant takes some time to provide a detailed (if not clear) account of the meaning of the term ‘analogy’ and his reasons for his employment of it, in the Transcendental Dialectic on the other hand, Kant’s employment of the term seems far less technical. It would seem on the face of it, that Kant has two senses of ‘analogy’: one technical sense reserved for those constitutive principles of the understanding as laid out in the Analytic, and another casual and commonplace use of the term. This picture, although it contains elements of truth, is ultimately misleading. I argue for three claims in this paper. Firstly, I suggest that there can be found in the first Critique a unified conception of analogy. Secondly, I argue that Kant self-consciously differentiated his employment of analogy from the employment that can be found in many early modern philosophers, e.g. Locke. Thirdly, I will tentatively suggest that this interpretation of analogy can aid us in addressing certain contentious areas of transcendental idealism, most notably the account of causation.

In this paper I consider Hume's position on the analogy between moral qualities and secondary qualities. Although some have suggested that Hume's use of the analogy is important to his moral philosophy, others have disputed its significance to Hume. My position in this paper is that Hume believes there are indeed similarities between moral and secondary qualities that illuminate the nature of virtue. This paper is divided into two parts. In the first, I consider Hume's point(s) in raising the analogy by arguing for four similarities between moral qualities and secondary qualities that he likely had in mind; and in the second, I respond to various objections alleging that Hume did not, and indeed, could not, rely on the analogy in any substantial way.
