ABSTRACT
The problem whether Reality is ultimately One or Many is inevitably suggested to metaphysicians by the diverse aspects of their own direct experience of the world. Reality, because systematic, must be the expression of a single principle in and through a multiplicity. Physical science learns more and more to look upon nature as a realm of interconnected events where no one fact is ultimately entirely independent of any other fact; political experience and social science alike reveal the intimate interdependence of human lives and purposes. The problem of Philosophy in dealing with the rival aspects of the world of experience then becomes that of deciding whether either of them can be adopted as the truth in isolation from the other. Any genuine Pluralism must be resolute enough to dismiss the idea of a systematic interconnection between its independent realities as an illusion of the human mind.
