Immanuel Kant

Kant credited Hume's skepticism about causation and induction with interrupting his own dogmatic slumber, and wrote the Critique of Pure Reason partly to answer it by grounding causation in the mind's own structuring of experience rather than in either pure reason or habit alone.

Schopenhauer identifies Kant's thing in itself with Will, rejecting a causal reading of the noumenal and phenomenal relation, a reinterpretation rather than a straightforward continuation of Kant's own position.

Schiller's aesthetic writings begin from Kant's Critique of Judgment, which he engaged critically rather than simply accepted.

Hegel's dialectic develops directly out of a critique of Kant's fixed categories and his sharp separation of appearances from things in themselves.

Goethe was highly ambivalent about Kant, dismissing the Critique of Pure Reason as a dungeon restraining free inquiry while praising the Critique of Judgment for treating nature and art as each purposive in themselves, an idea that shaped his own morphological method.

Kant is standardly credited as the movement's originating figure through the Critique of Pure Reason's transcendental idealism, even though he is not himself always classified as a German Idealist in the narrower sense reserved for Fichte, Schelling and Hegel; this atlas already carries Kant's own tradition fact as German Idealism.
