Abstract
Eleven previously published essays presenting a moderately unified argument in favor of the general conception of what Jonas calls the "Philosophy of Life," as well as detailed arguments pointing in the direction of a non-dualistic, realistic, and non-naturalistic philosophy of mind. The "nons" are deliberately placed, as Jonas spends the better part of the book questioning the tenability of dualistic and, especially, materialistic and mechanistically oriented theories of mind. With extraordinary historical sensitivity—at times threatening to dissolve a problem by laying bare the conceptual confusions which surrounded its origins—and with a better than working knowledge of biology and physiology, not to mention anthropology, Jonas argues, on the one hand, that the clues to the dynamism and structure of mind are to be found in such organic features as sentience, motility, and emotion: e.g., the conceptual strands that unite in the notions of causality and truth are rooted in the respective experiences of force and resistance, and vision. On the other hand, Jonas argues for the irreducibility of the subject-object structure of man's relation to nature on the grounds that this is the necessary burden of subjectivity. In all, the book is an impressive performance.—E. A. R.
