中国文化很早就形成了一种求真的传统。从认识的层面看，“真”首先表现为知识的正确性，这种正确性常常以“是”来表示，从而，“求真”与“求是”往往具有内在的一致性。早在先秦，墨家已指出，逻辑思维的功能和作用在于“明是非之分”，知识的“真”在这里就表现为“是”。 Chinese culture has long formed a kind of truth-seeking tradition. From an understanding level, “truth” first manifests itself as the correctness of knowledge. This correctness is often expressed as “yes.” Therefore, “truth seeking” and “seeking truth” often have internal consistency. As early as the pre-Qin period, Mohism has pointed out that the function and role of logical thinking lies in “dividing the difference between the right and the wrong,” and the “truth” of knowledge is manifested as “yes” here.
