The Physical Basis of Predication

This is a book about some of the basic concepts of metaphysics: universals particulars causality and possibility. Its aim is to give an account of the real constituents of the world. The author defends a realistic view of universals characterizing the notion of universal by considering language and logic possibility hierarchies of universals and causation. On the other hand he argues that logic and language are not reliable guides to the nature of reality. All assertions and predications about the natural world are ultimately founded on basic universals which are the fundamental type of universal and central to causation. A distinction is drawn between unified particulars (which have a natural principle of unity) and arbitrary particulars (which lack such a principle); unified particulars are the terms of causal relations and thus real constituents of the world. Arbitrary particulars such as events states of affairs and sets have no ontological significance.
