Based on the field work among the Azande and the analysis of ancient Chinese logic and the logic of Buddhism, this paper attempts to provide factual information for the argument for the "culture-based relativity of logic" in a descriptive way. Taking the deductive method as the classical research method, this paper argues for the existence of the culture-based relativity of logic in modern culture and other cultures. The validity of this argument is based on the findings of ethnographic as well as historical studies. This paper also seeks to prove by studying the interactions between different languages and ways of life that the classical research method was also built on cultural relativity.
