Abstract

Garnett attempts to defend realism while accepting much of what sense-data theorist have had to say. He does this by tracing the origin of our belief in external objects to the finding of "centres of resistance" in the experience of effort and resistance, these centres being symbolized by sensory qualia. Since the centres are found in experience they are not unknowable Lockean substances, and since the resistance is something over and above sensations of pressure they are not phenomenalistic patterns of sense-data. Though a great deal of the book is devoted to the "refutation" of particular arguments of Ryle and Austin, Garnett seems oblivious to the thrust of recent criticism of traditional accounts of the role of sense qualia in perception. All too often he allows assertion to replace argument.—A. E. J.
