Abstract

An original contribution to fundamental metaphysics. It offers a theory of possible individuals and possible worlds. It endeavors to show how its theory of possibility is adequate to various philosophical demands, such as those of modal logic. It employs its theory of possibility to clarify and resolve issues concerning such topics as disposition concepts and counterfactual conditionals. And it deals fruitfully with related metaphysical problems, such as essentialism, the doctrine of internal relations, and so on. The theory of possibility, spelled out formally and with considerable detail, is a development of the approach to possibility suggested by Rescher in his earlier book, Conceptual Idealism.
