“Whence the feeling in the judgment of taste is asked of everyone as if a duty” is a question that Kant asked at the end of Section 40 of Critique of Judgment. The answer to this question is related to one’s understanding of the relationship between two parts that are ostensibly irrelevant – Sections 31-40 and Sections 41-42 of “Deduction of Judgments of Taste”. Although scholars raised numerous explanations to unite these two parts and to interpret the latter part, they have not reached an agreement due to the difficulty in understanding Kant’s question. In order to solve this problem, it is necessary to return to the original context of Kant, and to clarify the necessity of the question on account of the distinction between the possibility of the necessity of the feeling in the judgment of taste and its actuality. Through new understanding of this question, we can then revisit Sections 41-42 and investigate the two possible answers Kant raised, explaining that Kant’s solution to this problem is “morality” in Section 42 rather than “sociability” in Section 41.
