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.
