Abstract

The question of whether an «understanding» of quantum phenomena is possible, as raised by Cushing , is considered in terms of a possible revision of basic ontological assumptions which would make rational the pursuit of such an understanding. It is argued that the quantum theory imposes new constraints on ontology which force us to revise classical presuppositions about attributing properties to physical systems, about locality and individuality, and about interaction and space‐like separability. Through such ontological revision, it is argued, one may still rationally hope to satisfy the typically realist thirst for an understanding of quantum phenomena
