Abstract: The author of this paper claims that seeking truth from facts,an important concept rooted in China straditional philosophy,is basically related and similar to materialist dialectical thinking.To be specific,the native concept of comprehending the nature of objects by observing the appearances of the samples,which leads to the metho dology of study ing objects nature,reflects the unity between objectivity and totality.The methodology of analogy inolves the dev elopments from specific objects to general conclusions,from general conclusions to specific objects again, which in fact covers such principles as induction & deduction,speciality & abstraction,analysis & conclusion and etc.The study of the relationship between nature and human,along with the obsenation of historical changes,demonstrates that the organic unity between historical methodology and logical methodology,the thought of rich experience emphasising the unity between theory and facts,between knowledge and behaviour are identical to dialectical materialism.
