This chapter elaborates on an intuitive criterion much discussed by ancient Greek philosophers regarding the conditions under which an object can be said to change. Heraclitus and Parmenides both denied the possibility of change. Heraclitus believed that changes are constantly occurring. Consequently, he needed to sever the connection between the idea that a thing changes and the idea that a change occurs, a connection expressed by the claim that a change occurs just in case a thing changes. Heraclitus was a (...) temporal parts theorist; therefore, to accept his view means abandoning the idea that the things that come into and go out of existence are also things that can alter. Parmenides, on the other hand, believed that nothing can become what it is not; therefore, nothing can change. (shrink)

In this paper, we argue that, omissions are not events or actions, but rather fact-like entities, and that, insofar as only events and actions can be causes, omissions cannot be causes. Nevertheless, since omissions can, and often do, play a role in the explanations of events, their place in such explanations must be found; and an attempt to find such a place is made.

It has been argued that there is a problem oftemporary intrinsics, the problem of explaininghow it is possible for things to possesssuccessively contrary properties, if a certaintheory about time, ``eternalism'', is true. Inthis paper, I consider whether there really issuch a problem and survey some standardsolutions to it. I argue for one of them, onewhich has been offered by Mark Johnston andPeter van Inwagen, and which I call the``exemplification-solution''''. I consider avariant on that solution offered by E.J. Lowe(and Sally Haslanger), (...) and I argue that thisvariant should be rejected. (shrink)

From time to time, the idea that enduring things can change has been challenged. The latest challenge has come in the form of what David Lewis has called a “decisive objection”, which claims to deduce a contradiction from the idea that enduring things change with respect to their temporary intrinsics, when that idea is combined with eternalism. It is my aim in this paper to explain why I think that no argument has yet appeared that deduces a contradiction from a (...) combination of eternalism and the idea that enduring things change with respect to their temporary intrinsics, except ones that do so by committing scope fallacies.
