Abstract: From the perspective of epistemology, Xiong Shili's Theory of Knowledge solves the problem of how people can prove the
truth and how the truth of natural science is made possible. Its unfinished part is a great pity, but also provides a lot of thinking space
and different solutions for the later Confucianism. The unfinished work was not only because of Xiong's own poor physical condition
and the difficult time, but also because of his lack of Western knowledge, especially the lack of scientific knowledge, and the logical
dilemma in his theory. Therefore, the contents of Xiong's unfinished theory may include the relationship between ontology and the
epistemology; the revert of the philosophical cognition, the distinctions between the new and old vijnanamatra schools and how the
consciousness converts to cognition.

Key words: Xiong Shili, consciousness, Theory of Knowledge, new vijnanamatra school
