Abstract
The subject of the research is the ways of substantiating the fundamental concept of aesthetic science -- the category of aesthetic in Kant's philosophy. The author examines such aspects of the topic as the content of transcendental philosophy, in which the mind indulges in a purely aesthetic occupation, draws for himself the structure of the whole, the congruence of the conditions of the work of art of a priori fulfillment of feelings, understanding the category of beauty under the sign of aesthetic intention cogito, analysis of how the artist combines the aesthetic aspects of the thing in itself with the incommensurable worlds in the work art. The aesthetic exists in a kind of universal space, which is defined by the transcendental as the "last foundation". The main conclusions of the study is the statement that, by analogy with transcendental aesthetics, Kant admits an aesthetic of pure practical reason that is not identical to it, expressing the hope that in the future it will be possible to comprehend both as elements of the unity of the entire faculty of pure reason. The author's special contribution to the study of the topic is the search in the context of the philosophical interpretation of the concept of aesthetic pleasure, as it is carried out within the framework of Kant's moral philosophy. The novelty of the research lies in identifying the dramaturgy of the foundations of the aesthetic, which does not presuppose any of its scenario as a basis for building aesthetic thinking, in revealing how the system of aesthetic interactions and syntheses correlates with structures ideally initial in relation to the world and man, with absolute foundations, without which there is no aesthetics.
