This article unfolds Kant's aesthetic judgment by delving into his creative philosophical construction. The main goal is to reveal the consistently unique transcendental flavor of Kant's thinking. Until recently, the third critique had not enjoyed the same attention by his Western colleagues as his first two critiques. Likewise, Chinese scholars have hardly discussed this work. In 1992, the late Professor Mou Tsung-san translated Kant's third critique into Chinese. He also composed a lengthy article criticizing Kant's principle of taste. He almost repudiated Kant's Aesthetics completely, especially disagreeing with Kant's using "subjective purposiveness" as the a priori principle of taste. He laid out his doubts and formulated "the principle of indetermination" to substitute for Kant's "subjective purposiveness". This article also reviews Mou's thesis, and attempts to offer an interpretation of the differences between Mou and Kant.
