The confirmation of this is found in his _Critique of Judgment_, which Schelling looked upon as the most important of the three _Critiques_, and which Hegel and other metaphysical idealists always especially esteemed.
For Kant art was always "a sensible and imaged covering for an intellectual concept." He did not look upon art as pure beauty without a concept. He looked upon it as a beauty adherent and fixed about a concept. The work of genius contains two elements: imagination and intelligence. To these must be added taste, which combines the two. Art may even represent the ugly in nature, for artistic beauty "is not a beautiful thing but a beautiful representation of a thing." But this representation of the ugly has its limits in the arts (here Kant remembers Lessing and Winckelmann), and an absolute limit in the disgusting and the repugnant, which kills the representation itself. He believes that there may be artistic productions without a concept, such as are flowers in nature, and these would be ornaments to frameworks, music without words, etc., etc., but since they represent nothing reducible to a definite concept, they must be classed, like flowers, with free beauties. This would certainly seem to exclude them from Aesthetic, which, according to Kant, should combine imagination and intelligence.
Kant is shut in with intellectualist barriers. A complete definition of the _imagination_ is _wanting_ to his system. He does not admit that the imagination belongs to the powers of the mind. He relegates it to the facts of sensation. He is aware of the reproductive and combinative imagination, but he does not recognize _fancy_ (_fantasia_), which is the true productive imagination.
Yet Kant was aware that there exists an activity other than the intellective. Intuition is referred to by him as preceding intellective activity and differing from sensation. He does not speak of it, however, in his critique of art, but in the first section of the _Critique of Pure Reason_. Sensations do not enter the mind, until it has given them _form_. This is neither sensation nor intelligence. It is _pure intuition_, the sum of the _a priori_ principles of sensibility. He speaks thus: "There must, then, exist a science that forms the first part of the transcendental doctrine of the elements, distinct from that which contains the principles of pure thought and is called transcendental Logic."
