This 1790 polemic by one of philosophy's most important and influential figures attempts to establish the principles that support the faculty of judgment. Kant's third critique--after Critique of Practical Reason and Critique of Pure Reason--remains one of the most important works on human reason. Its first part addresses aesthetic sensibility, and its second half focuses on the apparent teleology in nature's design of organisms. The Critique of Judgment forms the very basis of modern aesthetics by establishing the almost universally accepted framework for debate of aesthetic issues.
