Plutarch, On Having Many Friends - What Genuine Friendship Involves - Sadler's Lectures
This lecture discusses key ideas from the ancient philosopher and biographer Plutarch's short work On Having Many Friends.
This episode focuses specifically on a number of features of true or genuine friendship that he discusses in the work. Some of these are his own later interpretation of earlier authors who discuss friendship, like Aristotle and Cicero.

Immanuel Kant, Prolegomena - Clarifications About Idealism - Sadler's Lectures
This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics.
Specifically it focuses on the "Appendix", specifically the discussion distinguishing Kant's own critical or transcendental idealism from other, earlier forms of idealism ranging from that of Parmenides all the way down to Berkeley. Kant asserts that on some matters concerning space, time, experience, the understanding, and reason his idealism is in fact the reverse of the other sort of idealism, and resolves problems that they cannot address.

Immanuel Kant, Prolegomena - Probability, Common Sense, And Metaphysics - Sadler's Lectures
This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics.
Specifically it focuses on the "Solution of the General Problem of the Prolegomena", specifically his discussion of two common philosophical approaches that will not work for developing a genuine metaphysics, or even just producing one valid a priori synthetic proposition. One of these is appealing to probability (Wahrscheinlichkeit) or conjecture (Mutmaßung). The other is appealing to sound common sense (Menchenverstand).

Immanuel Kant, Prolegomena - Critique And Metaphysics As Science - Sadler's Lectures
This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics.
Specifically it focuses on the "Solution of the General Problem of the Prolegomena", where Kant contrasts the kind of metaphysics that can be developed after the critique of pure reason (by itself) with what passes as metaphysics (dogmatic or "school" metaphysics), and discusses how critique can carry us beyond the skepticism the dialectic of reason inevitably leads to if we do not engage in critique.

Immanuel Kant, Prolegomena - How Does Reason Set Boundaries? - Sadler's Lectures
This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics.
Specifically it focuses on he conclusion of the third part, specifically his discussion of the boundaries (Grenzen) for reason. These limits take place where we go beyond the field of experience into the "empty space" that is the field of the noumena or things in themselves. Reason not only recognizes these limits but also imposes them upon itself and on the faculty of understanding.

Specifically it focuses on the conclusion of the third part, specifically what he calls the "natural ends of reason's uses of transcendent concepts."

Immanuel Kant, Prolegomena - Deism, Theism, And Anthropomorphism - Sadler's Lectures
This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics.
Specifically it focuses on the conclusion of the third part, specifically his discussion of the distinction between deism and theism, and David Hume's critique of both standpoints for, among other things, engaging in "anthropomorphism". Kant argues that deism involves only a "symbolic anthropomorphism", and that it relies upon analogy properly defined and understood
