A. Horowitz has recently argued against semantic externalism. In this paper, I will show that his arguments are unsuccessful, owing to misconceptions regarding the nature of that semantic view.

Harold Langsam has recently presented a novel observational account of self-knowledge. I critically discuss this account and argue that it fails to provide a uniform understanding of how we are able to know the contents of our own thoughts.

In The Conscious Mind, D. Chalmers appeals to his semantic framework in order to show that conceivability, as employed in his "zombie" argument for dualism, is sufficient for genuine possibility. I criticize this attempt.

In "Externalism, Self-Knowledge and Skepticism,"' Kevin Falvey and Joseph Owens argue that externalism with respect to mental content does not engender skepticism about knowledge of content. They go on to argue that even when externalism is freed from epistemological difficulties, the thesis cannot be used against Cartesian skepticism about knowledge of the external world. I would like to raise some questions about these claims.

Parfit's most controversial claim about personal identity is that personal identity does not matter in the way we uncritically think it does) I would like to analyze Parfit's reasons for making this claim. These reasons are complex, and they stand in some tension with one another. I would like to examine them carefully and to try to arrive at the strongest case that can be made for Parfit's controversial claim about what matters.

In chapter 1 of Reason, Truth, and History, Hilary Putnam argues from some plausible assumptions about the nature of reference to the conclusion that it is not possible that all sentient creatures are brains in a vat. If this argument is successful, it seemingly refutes an updated form of Cartesian skepticism concerning knowledge of physical objects. In this paper, I will state what I take to be the most promising interpretation of Putnam's argument. My reconstructed argument differs from an argument (...) strongly suggested by Putnam's text. I will show that the latter argument obviously does not work. The more promising argument which I reconstruct on behalf of Putnam raises some interesting questions about the relation between the contents of one's beliefs and one's environment and about how this relation affects the evaluation of anti-skeptical arguments. I conclude that my reconstructed argument ultimately fails as a response to Cartesian skepticism: the argument engenders a skepticism about knowledge of meaning, or propositional content, which undercuts its anti-skeptical force.

In "Of Personal Identity,", Hume attempts to explain how one arrives at the fiction of a substantial self which retains its numerical identity through time. In "Of Scepticism with Regard to the Senses," Hume offers a similar explanation of the origin of another fiction - that of objects which enjoy a continued and distinct existence. In this paper, I will argue that his pair of parallel explanations does not jointly account for the pair of fictions to be explained.

It seems that, whereas a person's death needn't be a bad thing for him, it can be. In some circumstances, death isn't a "bad thing" or an "evil" for a person. For instance, if a person has a terminal and very painful disease, he might rationally regard his own death as a good thing for him, or at least, he may regard it as something whose prospective occurrence shouldn't be regretted. But the attitude of a "normal" and healthy human being (...) - adult or child - toward the prospect of his death is different; it is not unreasonable in certain cases to regard one's own death as a bad thing for oneself. If this is so, then the question arises as to why death is bad, in those cases in which it is bad. (shrink)

In "Nozick on Scepticism", Graeme Forbes attempts to establish a Transmission Principle for knowledge which has been challenged by a number of anti-sceptical philosophers (such as Nozick). This principle (or something like it) seems to be required by Cartesian sceptical arguments, so if it could be refuted, this would apparently rid us of such scepticism. I do not believe that Nozick or anyone else has refuted the principle, yet I will argue that Forbes has certainly failed to establish it.

In part I of the present work, I used the term 'Kantian transcendental argument' to refer to any argument which purports to establish that the existence of outer objects is a logically necessary condition for the possibility of self-conscious experience. In this second part, then, I examine Kantian transcendental arguments which proceed from the premise that one is the subject of widely construed self-conscious experience.

A Kantian transcendental argument is an argument which purports to show that the existence of physical objects of a certain general character is a condition for the possibility of self-conscious experience. Both the Transcendental Deduction and the Refutation of Idealism satisfy this characterization. But we have seen that even a successful Kantian transcendental argument would be somewhat disappointing. Even though such an argument would refute the extreme Cartesian skepticism about the very existence of physical objects, it would not certify any (...) of one's claims to know facts about particular physical objects: it would not refute the weaker skeptical position I have sketched.5 How- ever, it would clearly be of great interest if one could show that the existence of physical objects is a condition for the possibility of self- conscious experience. Accordingly, I would like to investigate some problems surrounding the construction of Kantian transcendental arguments. (shrink)
