Summary of Ph.D. Thesis
The purpose of my thesis is to demonstrate that metaphysics is a necessary discipline – necessary in the sense that any type of rational activity whatsoever would be impossible without a metaphysical background or metaphysical presuppositions. The thesis consists of a brief historical introduction of certain important views concerning the nature of metaphysics and of a longer survey of the status of metaphysics in the context of contemporary analytic metaphysics.
