Abstract
The central thesis of this treatment of Aristotle's philosophy of mind is that Aristotle's writings contain a coherent theory of perception which is explanatory of a variety of psychological activities such as sense perceiving, imagining, remembering, dreaming and thinking. The approach taken rejects the developmental theory of Jaeger and others, and assumes that the psychological theses found in the De Anima and the Parva Naturalia form a continuous exposition of one psychological theory.
