On Buber's 1923 book about the fundamental human position: As children, and historically, we start fully absorbed in relation with another person (like mom). Before that, we have no self-consciousness, no "self" at all. It's only by having these consuming "encounters" that we gradually distinguish ourselves from other people, and can then engage in what we'd normally consider "experience," which Buber calls "the I-It relation." Buber thinks that unless we can keep connected to this "I-Thou" phenomenon, through mature relationships, art, and nature. With guest Daniel Horne.

On Rudolph Carnap's The Logical Structure of the World (1928). What can we know? Carnap thinks that all the various spheres of knowledge are logically interrelated, that you can translate sentences about any of these into sentences about sets of basic, momentary experiences.

On W.V.O. Quine's "On What There Is" (1948) and "Two Dogmas of Empiricism" (1951). What kind of metaphysics is compatible with science?
