This lecture discusses key ideas from the ancient philosopher and biographer Plutarch's short work On Having Many Friends. This episode focuses specifically on his advice that, if we want to have good friendships, we need to try and test people before becoming fully friends with them. This echoes advice given earlier by authors like Cicero, Aristotle, and Seneca. Unfortunately, Plutarch says, many people make friends first, and then come to regret their commitment to people whose characters are not particularly good.

Guest William James discusses the relationship between certitude and truth, distinguishing empiricism and absolutism. He challenges the idea of absolute certainty in knowledge and explores the limitations of truth criteria throughout philosophy.

This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics. Specifically it focuses on his discussion in the Second Part Of The Transcendental Problem: How Is Pure Natural Science Possible? Specifically this bears upon Kant's distinction between pure or universal laws of nature, which can be known a priori and which are the conditions for the possibility of experience, and empirical laws of nature, which can be grasped through experience.

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.

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).

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.

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.

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 what he calls the "natural ends of reason's uses of transcendent concepts." Kant notes that what he is engaging in is conjecture rather than deriving knowledge. He also clarifies whether or not this study fits into the domain of metaphysics proper.
