This lecture discusses the ancient Greek philosopher Aristotle' work, On Interpretation, focusing on his discussion of propositions (apophanseis), which are a common type of sentence (logos), characterized by being either true or false. Propositions are generally affirmations (kataphaseis) or denials (apophaseis), and are the main focus of the work On Interpretation.To support my ongoing work, go to my Patreon site - www.patreon.com/sadlerIf you'd like to make a direct contribution, you can do so here - www.paypal.me/ReasonIOYou can find over 4,000 philosophy videos in my main YouTube channel - www.youtube.com/user/gbisadlerPurchase Aristotle's On Interpretation - amzn.to/3nS55ud
