I favour an analysis of selfhood which ties it to the possession of certain kinds of first-person knowledge, in particular de re knowledge of the identity of one's own conscious thoughts and experiences. My defence of this analysis will lead me to explore the nature of demonstrative reference to one's own conscious thoughts and experiences. Such reference is typically ‘direct’, in contrast to demonstrative reference to all physical objects, apart from those that are parts of one's own body in which one can localize sensations or which are directly subject to one's will. My conclusion will be that the semantic distinction between ‘direct’ and ‘indirect’ demonstrative reference helps to delineate the metaphysical boundary between oneself and the rest of the world. But I do not contend that one is to be identified with one's own body: indeed, I shall try to show that one can know a priori that no such identity can obtain.

Substantial change occurs when a persisting object of some kind either begins or ceases to exist. Typically, this happens when one or more persisting objects of another kind or kinds are subjected to appropriate varieties of qualitative or relational change, as when the particles composing a lump of bronze are rearranged so as to create a statue. However, such transformations also seem to result, very often, in cases of spatiotemporal coincidence, in which two numerically distinct objects of different kinds exist in exactly the same place at the same time, such as a statue and a lump of bronze. Various attempts to resist this way of describing the results of such transformations are examined and found wanting and objections to the possibility of cases of spatiotemporal coincidence are rebutted

Construing miracles as \textquotedblleft{}violations,\textquotedblright I argue that a law of nature must specify some kind of possibility. But we must have here a sense of possibility for which the ancient rule of logic---ab esse ad posse valet consequentia---does not hold. We already have one example associated with the concept of statute law, a law which specifies what is legally possible but which is not destroyed by a violation. If laws of nature are construed as specifying some analogous sense of what is naturally possible, then they need not be invalidated by a (rare) violation, and Humean miracles remain a genuine possibility.

Metaphysical realism is the view that most of the objects that populate the world exist independently of our thought and have their natures independently of how, if at all, we conceive of them. It is committed, in my opinion, to a robust form of essentialism. Many modern forms of anti-realism have their roots in a form of conceptualism, according to which all truths about essence knowable by us are ultimately grounded in our concepts, rather than in things 'in themselves'. My aim is to show that conceptualist anti-realism is an incoherent doctrine and how we can support metaphysical realism and robust essentialism, while still properly acknowledging the cognitive role of concepts in mediating our grasp of the nature of mind-independent reality.
