A critical discussion of Shoemaker's argument for the possibility of time without change, intended as an argument against relationist conceptions of time. A relational view of time is proposed based on the primitive identity of events (or whatever entities are the basic subjects of change and lack thereof).

Frank Jackson has famously argued that there is no logical space for the view which understands moral properties as non-natural properties of their own unique kind. His argument is based on two steps: firstly, given supervenience and truth-aptness of moral claims, it is always possible to find a natural property which is necessarily co-instantiated with a given moral property, and secondly that there are no distinct necessarily co-instantiated properties. I argue that this second step of the argument must rely on (...) a controversial nominalist view of properties. In contrast, if we accept universals or tropes, there is logical space also for non-natural moral properties even if they are necessarily co-instantiated with natural properties. (shrink)

This thesis analyses the ontological nature of quantum particles. In it I argue that quantum particles, despite their indistinguishability, are objects in much the same way as classical particles. This similarity provides an important point of continuity between classical and quantum physics. I consider two notions of indistinguishability, that of indiscernibility and permutation symmetry. I argue that neither sort of indistinguishability undermines the identity of quantum particles. I further argue that, when we understand in distinguishability in terms of permutation symmetry, (...) classical particles are just as indistinguishable as quantum particles; for classical physics also possesses permutation symmetry.
