Abstract
Notes by Dr. Robert Gahringer, who was C.I. Lewis' assistant at Harvard, Dr. Francis H. Parker, and those of the editor were used to reconstruct Lewis' lectures in Phil. 130, Kant, as those lectures were presented at Harvard in the late 40's and early 50's. The test of the reconstruction includes a detailed discussion of European epistemology in the period before Kant in addition to Lewis' interpretation of Kant's epistemology, critique of metaphysics, theology, and a brief presentation of his moral philosophy.
