Abstract
Everson introduces the ‘spiritualist’ and the ‘literalist’ readings. He offers some criticism of the ‘spiritualist reading’ in this chapter. The spiritualist must explain why the matter of a sense organ is not affected in perception. Everson argues that Aristotle's account implies that there is material change of the sense organ in perception. Firstly, there is Aristotle's insistence that each sense organ has a particular material constitution, and secondly, there is the claim that, in perception, the sense organ becomes like the object.
