The book indags the relationship between imagination and understanding, the association of intuitions to concepts and their intuitions by confluenceing on ideas of reason and aesthetic ideas. How the act of subsumption of the faculty of judging equates in art to singular inner feeling and makes a transit of its individual interest to a universal interest of complacency. Oriented from the description and analysis of aesthetics in the philosophy of Immanuel Kant, in particular in his work "Critique of Judgment" (often called the Third Critique) the author derives towards a hermeneutic and comprehensive aesthetic reflection that entails a theory of the nature of art and artistic creation. Sensitivity and imagination are the basis for explaining the processes that give rise to the realization of cognitive and intellective actions (and activities), ethical and practical, aesthetic and artistic. Sensitivity is the beginning of the reflective imagination of transcendental character and foundation of the aesthetic subject and aesthetic consciousness.
