عنوان مقاله [English]
In the first Critique, Kant delineated the principles of metaphysics of nature and in the second Critique, those of metaphysics of morality. Since these two kinds of principles were essentially distinguished, there appeared an absolute gap between nature and morality, which Kant called abyss or gulf and emphasized that it is "incalculable". That is, if one considers only the first and the second Critique, one should accept the dualism in the essence of subject. Kant, however, takes over in the third Critique the task of investigating the possibility of transition between the two sections of the dualism.
In this paper, we try first to clarify what it means that a transition occurs between nature and morality and then to show how it occurs. Before that, however, we should transform the metaphorical expression of "gulf" into a logical one in order to get the problem right. Once this is done, the meaning of transition becomes clear. In order to delineate how the transition is realized, we should appeal to concepts of the beautiful and the sublime. The transition in the sphere of the beautiful occurs in three instances: intellectual interest in beautiful, the genius, and being the symbol of morality. It will be clear that the sublime represents the possibility of transition in two respects: by introducing the idea of humanity and morality and by aesthetic representation of reason "as both theoretical and practical" which is nothing but unity of the first and the second part of Kantian philosophy.
