Aristotle, On Interpretation - Contrary and Contradictory Propositions - Sadler's Lectures

Author: Lectures on classic and contemporary philosophical texts and thinkers by Gregory B. Sadler May 2, 2026 Duration: 12:42
This lecture discusses the ancient Greek philosopher Aristotle' work, On Interpretation, focusing on his discussion of contrary and contradictory propositions, both of which are ways in which propositions are opposed to each other, with contradictories being more opposed to each other than contraries. With contrary propositions, if they are universal, one of them must be false (and it is possible for both of them to be false). With contradictory propositions, one of them must be true and the other false.
