As an important school of contemporary neo-scholasticism, transcendental Thomism had the merit of incorporating contemporary philosophical trend of subjective turn and the supplement of Aquinas' traditional metaphysics. On the one hand, its thesis generally recognized Kant's study of subject consciousness and affirm its argument about the existence of transcendental functions; on the other hand, Thomism re-revealed and understood an subject's active cognitive power and approved man's inquisitive and comprehensive power as the medium between the transcendental subject and the absolute transcendentalist in order to construct the argument of achieving being through transcendental power. This article is mainly meant to explicate the inheritance and transformation of such a theory. It discusses the major Thomists- Maréchal and Lonergan's comprehensive and critical study about Kant's concepts and methods of transcendence, and focuses on the studies of different aspects. This article maintains that, Maréchal used his "metaphysical critique" to supplement Kant's "transcendental critique". And Lonergan used the concept of "insight" to point out the transcendental properties of men. They both affirm that the dynamic functions and the use of "critique" in the faculties of cognitivities are the transcendental essence of the being of men. In this manner they surmount Kant's intuitionism. And in the aspect of transcendental philosophy they supplement Kant's transcendental methods with a distinction.
