This is the third in a series where I'm joined by Eric Taxier to discuss Kant's First Critique, the Critique of Pure Reason. In this episode we discuss the Introduction to the Critique. The first segment discusses Kant's conception of the collaboration between the object and our faculties for comprehending that object as well as the distinction between the a priori and the a posteriori. The second segment turn to the Kantian distinction between the analytic and the synthetic and examines the notion of the analytic as involving containment. The third segment zeroes in on the synthetic and the manner in which we are a necessary component of the act of synthesis. We also examine the troubling (for many) notion that math exemplifies the synthetic rather than the analytic.
