As standardly conceived, an illusion is an experience of an object o appearing F where o is not in fact F. Paradigm examples of color illusion, however, do not fit this pattern. A diagnosis of this uncovers different sense of appearance talk that is the basis of a dilemma for the standard conception. The dilemma is only a challenge. But if the challenge cannot be met, then any conception of experience, such as representationalism, that is committed to the standard conception is false. Perhaps surprisingly, naïve realism provides a better account of color illusion.An apparence ymaad by som Magyk. Chaucer

In his 1904 letter to G.F. Stout, Cook Wilson distinguishes objective and sub- jective conceptions of appearance, and provides a diagnosis for the modern acceptance of the subjective conception in terms of a confused misdescrip- tion of the objective appearances that perceptual experience affords. More- over, Cook Wilson links subjective appearances with idealism, the suggestion being that perceptual appearances must be objective if they are to afford us with something akin to proof of a world without the mind.

Sight is a capacity, and seeing is its exercise. Reflection on the sense in which sight is for the sake of seeing reveals distinct relations of dependence between sight and seeing, the capacity and its exercise. Moreover, these relations of dependence in turn reveal the nature of our perceptual capacities and their exercise. Specifically, if sight is for the sake of seeing, then sight will depend, in a certain sense, upon seeing, in a manner inconsistent with experiential monism. Thus reflection on the power of perception forms the basis of an argument for experiential pluralism.

The first main idea is that standard noncognitivism is a syndrome of three logically distinct claims. Standard noncognitivists claim that moral judgment is not belief or any other cognitive attitude but is, rather, a noncogntive attitude more akin to desire; that this noncognitive attitude is expressed by our public moral utterances; and, hence, that our public moral utterances lack a distinctively moral subject matter and so are not answerable to the moral facts. Notice, however, that these are logically distinct claims—the first is a psychological claim, the second and third, positive and negative semantic claims, respectively. We can regiment the familiar technical vocabulary as follow.

One cannot give too many or too frequent warnings against this laxity, or even mean cast of mind, which seeks its principle among empirical motives and laws; for, human reason in its weariness gladly rests on this pillow and in a dream of sweet illusions (which allow it to embrace a cloud instead of Juno) it substitutes for a morality a bastard patched up from limbs of quite diverse ancestry, which looks like whatever one wants to see in it but not like virtue for him who has once seen virtue in her true form.

This essay explores the commitments of modal structuralism. The precise nature of the modal-structuralist analysis obscures an unclarity of its import. As usually presented, modal structuralism is a form of anti-platonism. I defend an interpretation of modal structuralism that, far from being a form of anti-platonism, is itself a platonist analysis: The metaphysically significant distinction between (i) primitive modality and (ii) the natural numbers (objectually understood) is genuine, but the arithmetic facts just are facts about possible progressions. If correct, modal structuralism is best understood not as an alternative to, but as a species of, platonism.

The essay argues that, on their usual metalinguistic reconstructions, the open question argument and Frege’s puzzle are variants of the same argument. Each are arguments to a conclusion about a difference in meaning; each deploy compositionality as a premise; and each deploy a premise linking epistemic features of sentences with their meaning (which, given certain meaning-platonist assumptions, can be interpreted as a universal instantiation of Leibniz’s law). Given these parallels, each is sound just in case the other is. They are, in fact, unsound. The essay first argues that reformulations of these arguments directly in terms of Leibniz’s law are unsound and then that subarguments of the metalinguistic versions are unsound for structurally similar reasons. Finally, given how the theory/observation distinction is deployed in linguistic practice, the meaning-platonist assumptions are shown to be optional.

The presence of the fiery substance illuminates the transparent medium. White (leukon) corresponds to the presence of this determinant of what is actually transparent. Conversely, black (melaton) corresponds to its absence. The absence of the fiery substance darkens the transparent medium. White and black are thus associated with a fundamental condition on the visibility of remote external particulars. No doubt in part because of this Aristotle attempts to explain the other hues in terms of the ratio of white and black. He considers three such accounts, in terms of (1) juxtaposition, (2) overlap, and (3) mixture, advocating the third. On all three accounts chromatic hues are determined by white and black in various ratios, the accounts differing only in how these ratios are implemented

Producing language that other people will be able to understand involves not just having a picture in your mind of the scenario…You have to deploy a shared linguistic system, according to established rules, using lexemes of known meaning, to present that picture to others in a way that will work for them. You have to consider whether there are other ways of viewing the situation at hand. You have to examine the wording you have chosen to see if it has ambiguities or unclarities. You have to put yourself in the place of a person who did not [develop the picture], and you have to ask yourself whether they would understand..

CHANGE SLIDE Go through outline of talk CHANGE SLIDE It is my sincerest hope that if there is one thing that people take away from Moral Fictionalism, it is the recognition that standard noncognitivism involves a syndrome of three, logically distinct claims. Standard noncognitivists claim that moral judgment is not belief or any other cognitive attitude but is, rather, a noncognitive attitude more akin to desire; that this noncognitive attitude is expressed by our public moral utterances; and, hence, that our public moral utterances lack a distinctively moral subject matter and so are not answerable to the moral facts.

Unless you are a Frege scholar, or a philosopher of mathematics, if you are familiar at all with Frege’s work, you are most likely familiar with his groundbreaking work in the philosophy of language. You might know that Frege was a mathematician who sought to establish the covertly logical subject matter of arithmetic, a project whose demands drove Frege to his logical investigations and reflections on language. But most likely the connection between Frege’s mathematical research and his philosophy of language remains elusive for you.

Philosophy of mathematics is in an alienated state. While regarded by the profession as a serious and legitimate subdiscipline, a passing knowledge of its subject matter is considered something of a luxury—or at least not required of a conscientious philosopher the way a passing knowledge of logic is. Philosophy of mathematics is thus regarded with a benign neglect: best left to the experts, whose opinions should be deferred to, but mostly irrelevant to the central concerns of the working philosopher. Its practitioners, however, often display a strikingly different attitude. Much of the enthusiasm for the subject matter derives from the recognition that undertaking and evaluating a position in the philosophy of mathematics involves undertaking and evaluating substantive commitments of general philosophical interest. Indeed many practitioners, though by no means blind to the intrinsic interest of their discipline, regard philosophy of mathematics also as a means of addressing more general issues in philosophy. Unfortunately the significance of philosophy of mathematics to the work of the nonspecialist has for the most part been under appreciated.
