Ignorance and Imagination advances a novel way to resolve the central philosophical problem about the mind: how it is that consciousness or experience fits into a larger naturalistic picture of the world. The correct response to the problem, Stoljar argues, is not to posit a realm of experience distinct from the physical, nor to deny the reality of phenomenal experience, nor even to rethink our understanding of consciousness and the language we use to talk about it. Instead, we should view the problem itself as a consequence of our ignorance of the relevant physical facts, Stoljar shows that this change of orientation is well motivated historically, empirically, and philosophically, and that it has none of the side effects it is sometimes thought to have. The result is a philosophical perspective on the mind that has a number of far-reaching consequences: for consciousness studies, for our place in nature, and for the way we think about the relationship between philosophy and science.

Invariabilism is the view that the same theory of welfare is true of every welfare subject. Variabilism is the view that invariabilism is false. In light of how many welfare subjects there are and how greatly they differ in their natures and capacities, it is natural to suppose that variabilism is true. I argue that these considerations do not support variabilism and, indeed, that we should accept invariabilism. This has important implications: it eliminates many of the going theories of welfare while making some of the remaining ones more attractive.

The debate over physicalism in philosophy of mind can be seen as concerning an inconsistent tetrad of theses: (1) if physicalism is true, a priori physicalism is true; (2) a priori physicalism is false; (3) if physicalism is false, epiphenomenalism is true; (4) epiphenomenalism is false. This paper argues that one may resolve the debate by distinguishing two conceptions of the physical: on the theory-based conception, it is plausible that (2) is true and (3) is false; on the object-based conception, it is plausible that (3) is true and (2) is false. The paper also defends and explores the version of physicalism that results from this strategy.
