In this important and broad-ranging book, Israel Scheffler explores the various ways in which the mind functions symbolically. This involves considering not only the worlds of the sciences and the arts, but also such activities as religious ritual and child's play. The book offers an integrated treatment of ambiguity and metaphor, analyses of play and ritual, and an extended discussion of the relations between scientific symbol systems and reality. What emerges is a picture of the basic symbol-forming character of the mind.
