Abstract

"This is a full original version of Makowski's work on Aristotelian dunamis (shortened & revised version has been previously published as "Metaphysics of Practical Philosophy" paper). The author presents the Aristotelian conception of capacity/potentiality (dunamis) – one of the most important in Aristotle’s metaphysics. A closer inspection allows to draw conclusion, that the concept of capacity is an important link between ‘theory’ and ‘practice’ (metaphysics on the one side, and practical – ethical, rhetorical, political – skills, on the other). A picture of the connection between theory and practice is based on the most important parts of Metaphysics (books delta and theta), it relates metaphysical definitions to an essential element of Aristotelian practical philosophy – the concept of virtue (aretê). In the practical works of Aristotle, we can find different definitions of aretê: in Nicomachean Ethics Aristotle defines aretê using the notion of disposition (hexis), but in Rhetoric he formulates a definition based on the concept of capacity. Distinctive analysis of this inconsistency shows the significance of capacity in The Stagirite’s philosophy."
