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.

Causal closure arguments against interactionist dualism are currently popular amongst physicalists. Such an argument appeals to some principles of the causal closure of the physical, together with certain other premises, to conclude that at least some mental events are identical with physical events. However, it is crucial to the success of any such argument that the physical causal closure principle to which it appeals is neither too strong nor too weak by certain standards. In this paper, it is argued that various forms of naturalistic dualism, of an emergentist character, are consistent with the strongest physical causal closure principles that can plausibly be advocated.

In this paper, it is argued that metaphysics, conceived as an inquiry into the ultimate nature of mind-independent reality, is a rationally indispensable intellectual discipline, with the a priori science of formal ontology at its heart. It is maintained that formal ontology, properly understood, is not a mere exercise in conceptual analysis, because its primary objective is a normative one, being nothing less than the attempt to grasp adequately the essences of things, both actual and possible, with a view to understanding as far as we can the fundamental structure of reality as a whole. Accordingly, it is urged, the deliverances of formal ontology have a modal and epistemic status akin to those of other a priori sciences, such as mathematics and logic, rather than constituting rivals to the claims of the empirical sciences, such as physics.

Some formal ontological relations are identified, in the context of an account of ontological categorization. It is argued that neither formal ontological relations nor ontological categories should themselves be regarded as elements of being, but that this does not undermine the claim of formal ontology to be a purely objective science. It is also argued that some formal ontological relations, like some ontological categories, are more basic than others. A four‐category ontology is proposed, in which two basic categories of universals and two basic categories of particulars are distinguished in terms of certain formal ontological relations characteristically obtaining between entities belonging to the different categories
