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.

Kant's Critique of Pure Reason
Lecture series examining Kant's Critique of Pure Reason. It remains a matter of controversy as to just what the central project of the Critique is, but surely one objective is to establish the character and range of objective knowledge in light of the limits of sense and reason. Lectures are intended to clarify the major claims advanced by Kant in this connection, and to test the arguments he adduces in their support.

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?
-
Kant's so-called "Copernican" revolution in metaphysics begins with the recognition of the observer's contribution to the observation.

-
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.
-
Kant argues that: "The synthetic unity of consciousness is... an objective condition of all knowledge.
-
Reason, properly disciplined, draws permissible inferences from the resulting concepts of the understanding. The outcome is knowledge.
