  A narrower usage of “change” is exemplified by change in the properties of a body over time, that is temporal change. This essay will focus on temporal change. We begin by separating the concept of change from several cognate concepts, specifically cause, time and motion. Then we briefly survey attempts by such thinkers as Parmenides and McTaggart to deny change. There follows an account of the problem of the instant of change, where it is concluded that the problem is too general to admit a single solution, but requires specification of further metaphysical principles envisaged as constraints on a type of solution. The final three sections, the bulk of the essay, consider the question of the consistency or inconsistency of change, which in one way or another looms over all our discussions. It emerges that the case for change as an inconsistent process is stronger than might be expected.
