Sadler's Lectures

This lecture discusses the ancient Greek philosopher Aristotle' work, On Interpretation, focusing on his discussion of what have come to be called "modalities" such as necessity, contingency, possibility, and impossibility, with the truth values of future seemingly contingent propositions in mind, for example that a sea-battle will or will not take place tomorrow. One possible approach is to say that since propositions must be either true or false, future propositions already are true or false of necessity and that we simply don't know their truth or falsity. Another is to say that it is necessary for them to be either true or false, but that neither of these truth values are necessary to contingent propositions referring to future events that have not yet happened.

This lecture discusses the ancient Greek philosopher Aristotle' work, On Interpretation, focusing on his discussion of what he calls propositions that contain "indefinite" subjects or predicates. These can be ambiguous and create problems for interpretation that do not arise when propositions are made universal or particular by using universal terms such as "all," "every" "no", "none", or when singling out a particular or using "some".

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.

This lecture discusses the ancient Greek philosopher Aristotle' work, On Interpretation, focusing on his discussion of universal and particular propositions. Universal (katholou) propositions will generally be indicated by terms like "all", "every" or "no" applied to the subject, and refer to an entire group or class of things. Particular propositions (kath' hekaston) apply to at least one individual subject, but could also be framed to include more. Aristotle does also note that not all propositions are universal or particular, since some of them could be indefinite.

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.

This lecture discusses the ancient Greek philosopher Aristotle' work, On Interpretation, focusing on his discussion of nouns or names (omonata), verbs (rhemata) and sentences (logoi). Sentences are significant parts of speech, often composed of nouns and verbs, but not all of them are propositions (apophanseis), since they are not all affirmations or denials which have either truth or falsity to them.

William Gass, The Case Of The Obliging Stranger - The Case and Moral Theories by Lectures on classic and contemporary philosophical texts and thinkers by Gregory B. Sadler

This is part 2 of the recording of my invited talk at Christopher Newport University, "Plato, Persons, And The Highest Good". It focuses on the question of whether the highest good in Plato is personal (as it would be e.g. for Christian Platonists) or impersonal (as it's usually taken to be). Centering the discussion on the ascent to the highest Good in the Symposium, I also discuss portions of the Republic, Phaedrus, Phaedo, Apology, and Gorgias

This lecture discusses key ideas from the 20th century pessimist philosopher and environmentalist Peter Wessel Zapffe's "The Last Messiah"

It focuses specifically on the final parts of the work, where he considers and rejects several possible solutions to the problem posed by modern society for the human animal beset by a surplus of consciousness and a tendency to fall into "cosmic panic" when realizing their existential condition. He then narrates the coming of a "last messiah", who has stripped their soul naked and subjected themselves to the most profound questioning, who advocates no longer reproducing and letting the human race die out.
