This paper notes that the question of “life” is discussed on the basis of the discussion of the aesthetics and teleology in Kant's Critique of the Power of Judgment. In fact, the word “life” is not frequently used in Critique of the Power of Judgment, nor are life-themed discussions highlighted. Nevertheless, if Kant's entire theory of aesthetics and teleology are read deeply, it will not be too difficult to find that aesthetic thinking is closely related to the feeling of life of human beings, and that the consideration of organisms, especially the natural end of life, is fundamentally related to the problems of life. Whether from the perspective of aesthetics based on subjective purposiveness or teleology based on objective purposiveness, life comes down to the question of the life of human beings and cannot be simply returned to epistemology or morality. This paper tries to show that aesthetics and teleology are important critical considerations to promote a new understanding of human beings based on life. To this end, we will first look at an aesthetic feeling of life from the point of view of aesthetics, followed by the natural end of organic life from the point of view of teleology. Finally, we will discuss the fact that aesthetics and teleology are in a corresponding relationship at the level of life, especially with the concept of “favor of nature” as a clue.
