The concept of"anumāna"is a core concept in early Indian Nyāya philosophy and logical thought.Through the analysis of this concept,it can be concluded that early Indian Nyāya logic is multifaceted.Firstly,there are similarities between early Nyāya logic and Aristotle's syllogism;so the former has the characteristics of deductive reason-ing.Secondly,early Nyāya logic has included the use of analogical reasoning; thus it possesses the characteristics of analogical reasoning.Thirdly,early Nyāya logic can be reconstructed according to the formal structure of abductive reasoning;therefore it also possesses the characteristics of abductive reasoning.The inspiration drawn from the mul-tifaceted characteristics is as follows.On the one hand,Indian logic has embodied the modern significance,that is,it can provide useful insights for the development of logics in artificial intelligence at present.On the other hand,the study of Eastern logic should also be based on the perspective of Eastern culture,and a comprehensive interpretation of Eastern logic may be achieved through mutual learning between the East and the West.
