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.
