Abstract: During Late Ming and Early Qing, bianxue (辨学) and bianxue (辩学) were used equally to refer to the whole or a part of deductive logic. In the process of the transmission of Logic to China during the Late Qing, it was translated as bianxue (辨学)，which meant the discipline of studying discernment and argument．bianxue ( 辨学) ’s status as the translation for“logic”was replaced by mingxue (名学) and lunlixue (论理学)．But the concept was extended, in the context of the “Theory of Western Learning Being of Chinese Origin”and“Interpreting China according to the West”, to a discipline of debate and was equated with bianxue (辩学), which referred to Chinese Logic. Equating the concepts of bianxue (辨学) and bianxue (辩学) was due to the nebulousness distinction between bian (辨) and bian (辩)in ancient Chinese and the limited the effect of the term bianxue (辨学) in the late Qing and, to some degree, its value for promoting logic into China and legitimating Chinese Logic and even Chinese Philosophy．
