The second chapter of book three of the De anima marks the end of Aristotle's discussion of sense-perception. The chapter is a long one and apparently rambling in subject matter. It begins with a passage that is usually taken as a discussion of some sort of self-awareness, particularly awareness that one is perceiving, although such an interpretation raises some difficulties. This paper reconsiders the problems raised by supposing that the question discussed in the first paragraph is ‘how do we perceive that we perceive?’, and suggests an alternative interpretation which would solve many of the difficulties and have the additional merit of restoring unity to the sequence of notes which go to make up the whole chapter.
