Naturalism or Idealism
PROBLEMS and ideas which promise to yield some measure of partial insight into their solution constitute the stock-in-trade of the philosopher. Hence I may best respond to the invitation to set forth my present philosophical beliefs by trying to formulate, not any framework of a completed system, but rather a single crucial issue. It is central in the sense that it arises-so it appears to me-in each of the major provinces of human experience. It is one important point of convergence of fundamental questions in Ethics and Logic, Epistemology and Metaphysics.
