Kant's only aesthetic work apart from the Critique of Judgment, Observations on the Feeling of the Beautiful and Sublime gives the reader a sense of the personality and character of its author as he sifts through the range of human responses to the concept of beauty and human manifestations of the beautiful and sublime. Kant was fifty-eight when the first of his great Critical trilogy, the Critique of Pure Reason, was published. Observations offers a view into the mind of the forty-year-old Kant.
