Abstract

This paper is concerned with a question in metaphysics. The question is: Is the world ultimately one, or is it many? It is neither a very profound nor a very complicated question. It is, on the contrary, very simple. But despite its simplicity, it expresses the most basic of all metaphysical problems.When two metaphysical problems, A and B, are so related that the statement of B assumes an answer to A, then we may fairly infer that A is more basic than B, and B less basic than A.
