In this paper I first address what I consider a central issue in the account of perception in Plato's Timaeus, namely, how the pathemata pass through the body to reach the soul, and thus become aistheseis. My point in section 1 is that in tackling this issue Plato aims to provide a firm physiological basis to the notion of perception that starts to emerge in the Theaetetus and the Philebus and is crucial to the late development of his theory of cognition. In the ensuing section I try to put the account of perception in the Timaeus into a historical perspective, aiming to highlight two points: a) Plato's de-scription of the way in which sensible impressions “travel” inside the body and interact with its parts and other constituents is largely indebted to previ-ous theories, such as those we find, for example, in Empedocles and a few Hippocratic writers; b) The leading role in this story (where internal air plays a significant supporting role) is played by blood flowing through the vascular system and thus performing a crucial cognitive function.

Abstract
In this paper I first address what I consider a central issue in the account of perception in Plato's Timaeus, namely, how the pathemata pass through the body to reach the soul, and thus become aistheseis. My point in section 1 is that in tackling this issue Plato aims to provide a firm physiological basis to the notion of perception that starts to emerge in the Theaetetus and the Philebus and is crucial to the late development of his theory of cognition. In the ensuing section I try to put the account of perception in the Timaeus into a historical perspective, aiming to highlight two points: a) Plato's de-scription of the way in which sensible impressions “travel” inside the body and interact with its parts and other constituents is largely indebted to previ-ous theories, such as those we find, for example, in Empedocles and a few Hippocratic writers; b) The leading role in this story (where internal air plays a significant supporting role) is played by blood flowing through the vascular system and thus performing a crucial cognitive function.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
