Abstract

The relationship of the identity of indiscernibles principle to other major metaphysical principles (e.g., relational doctrine of space and time, elimination of singular terms) is discussed, the aim being to outline the necessary requirements of a systematic metaphysics incorporating the former principle. the conclusion is that no adequate systematic metaphysics of this sort is defensible. throughout special attention is paid to modern logical formulation of the principle and to its role in quine's philosophy
