From the Nyaya Sutra and its commentaries, it can be seen that the logic proposed by ancient Nyaya mainly lies with “pramana”, which refers to means of right knowledge and usually was discussed by an ancient Indian philosophy. According to *Nyaya Sutras*, there are four means of attaining right knowledge: perception, inference, comparison and verbal testimony. The Nyaya's logic is mainly related to inference and its relevant theories can be divided into two parts. One is inferential theories about obtaining right knowledge and the other is analyses for the causation of fallacies or failure in the course of inference.
