On Cause, Reason And Categorization Of Mohist Canon Of The Role Of Inference

Mohist Cannon posed three basic logic concepts."Cause"(gu),"Reason"(li) and"Categorization"(lei), they are essential parts and conditions of inferences. They can conclude new topic or there will be difficutes in inferences without them.Researching them, we can recognize the inference forms of Mohist more accurately."Cause"is the causality of logic and it is the condition and basis of Mohist Cannon Logic inferences. Mohist Cannon divided"cause"into"big cause"(da gu) and"small cause"(xiao gu). The broad sense of cause is all basses of inferences. The cause of narrow sense is the direct cause of"San wu inference", and it is equal to the small condition of syllogism."Reason"is the regular, the principle, the standard, the inference model. In Mohist Cannon Logic"Reason"(li),"road"(dao),"effect"(xiao),"mothod"(fa) can explain together. Today, there are six standpoints, that explained"effet", but we think Mr. Liu Pei yu's standpoint is the best."Effect"is"method","standard". Meanwhile we don't agree Mr Chui Qing tian's view; we think"Three models"is one of the clear and standard inference forms.The same and difference of"Categorization"is the regular of inference. In this chapter, we analyzed the relation between"Categorization"and"Mou"inference.We think the examples of"shi er bu ran"are correct.so,we think"shi er bu ran"is a Non-Formal Logic inference ,and it doesn't effect the"shi er ran". The narrow sense categorizations are examples of"san wu"inference,"lei", and"li","gu"is the parts and conditions of"san wu"inference.In"San wu"inference,"Cause"is direct reason."Reason"(li) is the regular."Categorization"is the example.The"San wu"of its own unique characteristics and as Aristotle's syllogism is necessarily produce inference.It is an inevitable inference modality. It is very important in the logic history of the world.
