Influenced by the work of Dignaga, Bhāvaviveka's Madhyamika philosophy makes use of Buddhist epistemology. Candrakīrti, on the other hand, critiqued Bhāvaviveka's adoption of the epistemological ("pramana") tradition on the grounds that it contained a subtle essentialism. He quotes Nagarjuna's famous statement in the "Vigrahavyavartani" which says "I have no thesis" for his rejection of positive epistemic Madhyamaka statements. Candrakīrti held that a true Madhyamika could only use "consequence" ("prasanga"), in which one points out the inconsistencies of their opponent's position without asserting an "autonomous inference" ("svatantra"), for no such inference can be ultimately true from the point of view of Madhyamaka.
