PT - JOURNAL ARTICLE AU - Hloch, Roman TI - Two Aristotle's Propositions about the Sense Perception DP - 2017 Sep 30 TA - Aither PG - 4--21 VI - 9 IP - 2 AID - 10.5507/aither.2017.005 IS - 18037879 AB - The concept of sense perception constitutes considerable part of Aristotle's De anima. As such, this concept is abundant source of his philosophical thoughts. In this paper, I shall focus on two Aristotle's propositions about sense perception: 1) a sense organ is potentially as such, as his sense object is actually; 2) a sense is a capacity to receive sensible form without the matter. By analyzing this propositions, I shall expose their mutual connection. I shall also expose important and indispensable role of potentiality and actuality in Aristotle's concept of sense perception. I shall sketch the modern debate between materialist and spiritualist interpretations and possible solution of this disputation, which may answer the question about the character of change during the act of sense perception, and also the question about the role and relation between physiological sense organ and formal sense. By this I shall clarify both propositions 1) and 2) their relation.
