Buddhism and Logic
Posted by matthewbain
In the Buddhist tradition also, logic is subordinated to ‘revelation’: the Buddha’s teachings. Like Islam, Buddhism originally lacked a formal system of logic.
Islam borrowed Greek Aristotelian logic, creating Islamic philosophy whose famous exponents include Avicenna (Ibn Sina) and Averroes (Ibn Rushd). Islamic philosophy was the conveyor of Arisotelian logic into Christendom via Thomas Aquinas. Buddhism, on the other hand, borrowed the Indian Nyaya logical system and, as with other religions, found the fusion of logic and faith challenging.
In the 2nd century CE the protector Nagarjuna had restored the integrity of Buddha’s teaching by showing how all ‘dharmas’ are ultimately empty. ‘Dharmas’ are the categories of thought introduced by Buddha, but in the centuries after Buddha’s death they had been reified by the Abhidharmists.
Nagarjuna deconstructed the dharmas, showing that they were not ultimate realities, using the logical consequences of the Abhidharmists own arguments, but without establishing a formal logical system of his own. For this reason Nagarjuna’s Middle Way (Madhyamika) method was called ‘Prasangika’ meaning Consequentalist.
One group of Nagarjuna’s followers including Bhaviviveka attempted to fuse the Nyaya logical system which had been brought into the Buddhist fold by Dignaga. Their method was known as Madhyamika-Svatantrika because it didn’t just use the consequences of other people’s arguments to prove the Middle Way, rather they sought to establish the Middle Way view through reasons proposed from their own side (‘Svatantrika’).
Je Tsongkhapa in Tibet was the inheritor of all these systems because the monasteries he established taught logic, but his own realisation of the Middle Way followed a vision of Nagarjuna’s Prasangika follower Buddhapalita.
Tsongkhapa’s Middle Way shows that the ultimate emptiness of all phenomena is not a thing in itself that can be established positively through reasoning, but we shouldn’t dispense with logic in our meditative enquiries.
