Kant, the most revolutionary and important figure in Western philosophy since Aristotle, wrote the "Critique of Judgment" as the capstone of his trilogy of "Critiques." Through its investigation of the beautiful and the sublime, it set the terms for modern aesthetics and art criticism. Its discussion of the significance of nature is important for theology and science alike. Most important, the third "Critique"'s exploration of the contributions that scientific thinking and aesthetic sensitivity each make to our sense of humanity remains of the most profound significance to anyone interested in morality and the development of culture.
