 Turning now to other primary sources: there is a considerable amount of material on aesthetics, reflecting Kant’s views at various stages of his philosophical development, in the lectures and reflections on logic and anthropology. For more details on relevant material from these texts, the reader is referred to the endnotes of the Cambridge edition of the Critique of Judgment. Kant’s early work, Observations on the Sublime and the Beautiful (1764), has, in spite of its title, very little bearing on Kant’s aesthetic theory, and is more a work in popular anthropology.
