Abstract
Buddhist logicians have rejected the reality of universals on the one hand, and, on the other hand, given a substitute in the form of the doctrine of Apoha. The doctrine of apoha first appears in Dinnaga’s Pramanasamuccaya, according to which words and concepts are negative by their very nature. They proceed on thebasis of negation. They express their own meaning only by repudiating their opposite meaning. The Buddhist logicians talk of two types of knowledge, viz., pratyaksa, which is non- relational and anumana, which is relational. They accept nirvikalpaka pratyaksa as a pure pratyaksa, and savikalpaka pratyaksa has been merged with anumana by them. According to them, cognition is either a direct awareness of an object, which is independent of any mentalconstructionor it is an awareness of an object which is a mentalconstruction. Further, according to the Buddhist logicians inferences are of two kinds, viz., svarthanumana and pararthanumana. But they do not accept pararthanumana as a source of knowledge. Now, since perception is devoid of kalpana, perceptual knowledge is essentially non-linguistic and does not involve any general concept or universal. Thus,Apoha has no role to play in perceptual knowledge. On the other hand, savikalpaka pratyaksa and anumana are based on kalpana, thus according to the Buddhist logicians knowledge of universal is essential for both, savikalpaka pratyaksa and anumana.
