　　　　　As an occasional contribution to the theme of this current issue, this paper is just an introduction of Chinese epistemology in terms of the epistemological principles and methods in the doctrines of Hsun-tzu and Mo-tzu. Here we talk about how these two doctrines present the cognitive conditions, approaches, the classifications and statements about the nature of knowledge. This paper first explains specifically Mo-tzu's seven ways of inference, referring also to the three elements of discussion, induction, and reductio ad absurdum. The latter half of this article focuses on Hsun-tzu's theory of knowledge under the interactive relationship between Heaven and Man, in order to bring forward the epistemology of the doctrine of Hsun-tzu. In the end, the two epistemologies of the two doctrines are both examined and given suggestions.
