The religious pluralism of John Hick thought that the different sacred being worshiped by world religions were actually the responses to different believers given by one single transcendental ultimate reality. However, the thesis thinks that the transcendental ultimate reality, the core of Hick's pluralism, is but a made-up concept generated from cognitive limitation of human races. It transcends the historical representations of sacred being in order to become the common ground of conversation, nevertheless, in doing so, it also fails the task for it is insulated from living faith. Then, by the deconstruction of the concept of reality, the thesis will try to reconstruct the ground of common sacredness, achieving the conversion from the transcendental illusion to the transcendental turn, which could be the basis for the new possibility of religious pluralism and conversation.
