Particulars Actuality and Identity over Time vol 4

Volume 4 in the 5-volume series titled Analytical Metaphysics. The essays in this volume are concerned with three main issues. First what account can be given of the nature of a particular? Second is identity over time a basic and irreducible relation or can it be analysed? If so what is the correct analysis? Third what account can be offered of what it is to be actual? The final account of this volume involves the claim that actuality is a special property that is possessed by one and only one possible world.
