In this work, James Van Cleve examines the main topics from Kant's Critique of Pure Reason. Among the topics discussed in detail are Kant's transcendental idealism, necessity and analyticity, space and time, substance and cause, noumena and things-in-themselves, problems of the self, and rational theology. In a concluding chapter, Van Cleve relates Kant's thought to modern anti-realist approaches, in particular, the work of Putnam and Dummett. The work's orientation toward specific problems, rather than toward entire passages or sections of the text, allows the study to proceed in a natural and non-mechanical fashion that should make Kant's Critique more accessible to the serious student and scholar.
