The traditional epistemological problem of other minds seeks to answer the following question: how can we know someone else's mental states? The problem is often taken to be generated by a fundamental asymmetry in the means of knowledge. In my own case, I can know directly what I think and feel. This sort of self-knowledge is epistemically direct in the sense of being non-inferential and non-observational. My knowledge of other minds, however, is thought to lack these epistemic features. So what (...) is the basic source of my knowledge of other minds if I know my mind in such a way that I cannot know the minds of others? The aim of this paper is to clarify and assess the pivotal role that the asymmetry in respect of knowledge plays within a broadly inferentialist approach to the epistemological problem of other minds. The received dogma has always been to endorse the asymmetry for conceptual reasons and to insist that the idea of knowing someone else's mental life in the same way as one knows one's own mind is a complete non-starter. Against this, I aim to show that it is at best a contingent matter that creatures such as us cannot know other minds just as we know a good deal of our own minds and also that the idea of having someone else's mind in one's own introspective reach is not obviously self-contradictory. So the dogma needs to be revisited. As a result, the dialectical position of those inferentialists who believe that we know about someone else's mentality in virtue of an analogical inference will be reinforced. (shrink)

I reconsider the idea that there is an analogy between belief in other minds and belief in God, and examine two approaches to the relevant beliefs. The 'explanatory inductive' approach raises difficulties in both contexts, and involves questionable assumptions. The 'expressivist' approach is more promising, and presupposes a more satisfactory metaphysical framework in the first context. Its application to God is similarly insightful, and offers an intellectually respectable, albeit resistible, version of the doctrine that nature is a book of lessons.

Qualia--the "what it's like features" of minds--pose a great challenge to a materialist view of the world. The two strongest and most popular objections to materialism based on qualia are the Zombie Argument and the Knowledge Argument. The current dissertation defends materialism against these two popular arguments. ;I argue that if zombie worlds exist, then qualia cause no physical events--they're epiphenomenal$\sb{\rm p},$ or epiphenomenal with respect to the physical domain of our world. I argue, however, that there is good reason (...) to reject the view that qualia are epiphenomenal$\sb{\rm p},$ and thus that there is good reason to deny the existence of zombie worlds. In turn, I argue that the Knowledge Argument likewise requires the existence of zombie worlds, and thus that the Knowledge Argument should likewise be rejected. (shrink)
