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 Preamble on the peculiarities of all metaphysical knowledge, bearing upon what he takes to be a central problem that must be resolved if there is to be any genuine well-founded metaphysics, namely how it is that synthetic a priori cognitions (or judgements or propositions) are possible.
