Lecture 1/8. Both sense and reason are limited. Kant must identify the proper mission and domain of each, as well as the manner in which their separate functions come to be integrated in what is finally the inter-subjectively settled knowledge of science.
Lecture 2/8. The significant advances in physics in the 17th century stood in vivid contrast to the stagnation of traditional metaphysics, but why should metaphysics be conceived as a “science” in the first place?
Lecture 5/8. The very possibility of self-awareness (an “inner sense” with content) requires an awareness of an external world by way of “outer sense”. Only through awareness of stable elements in the external world is self-consciousness possible.
Lecture 6/8. Empiricists have no explanation for how we move from “mere forms of thought” to objective concepts. The conditions necessary for the knowledge of an object require a priori categories as the enabling conditions of all human understanding.
