About Prāsaṅgika school

The Prasangika school, which emphasized a more negative form of argumentation, was founded by Buddhapalita (c. 470–540), who wrote many works, including a commentary on Nagarjuna’s Madhyamika Karika. The school was continued by Chandrakirti, a famous logician of the 7th century.
