Material Alteration And Cognitive Activity In Aristotle's De Anima, John Sisko Dec 1995

Material Alteration And Cognitive Activity In Aristotle's De Anima, John Sisko

The Society for Ancient Greek Philosophy Newsletter

In this paper, I would like to sketch my account of the relation between cognitive activity and material alteration within Aristotle's psychological theory. I will begin by suggesting a new framework through which to view the important issues (§2). I will then show that on Aristotle's account material alteration is required both for any episode of perception in animals taken generally (§3) and for any episode of thought in human beings (§4). Finally, I will examine Aristotle's rationale for supposing that material alteration is required for human thought (§5).
