Madhyamaka — Śūnyatā, the Two Truths, and the Philosophy of the Middle Way
Nāgārjuna's Madhyamaka is the most radically anti-foundationalist philosophy in the Indian tradition. Not only is the self empty of inherent existence — all phenomena are. The two-truths doctrine (conventional truth / ultimate truth) preserves the world of experience while denying any metaphysical foundation to it. Madhyamaka's influence on Tibetan Buddhism, Zen, and Yogācāra is profound; its dialogue with Advaita Vedānta is philosophy's most searching debate about ultimate reality.
The prasaṅga method: refutation without counter-thesis
Nāgārjuna's method is not to advance a positive thesis but to show that every possible thesis about ultimate reality leads to absurdity (prasaṅga). He does not say 'reality is X instead of Y' — he shows that 'reality is Y' leads to contradiction. This is why Madhyamaka is so philosophically difficult and so influential: it refuses to give its opponents anything to refute.
The Mūlamadhyamakakārikā systematically applies this method to causation, time, motion, perception, the self, nirvāṇa, and the Buddha. In each case, the conclusion is the same: the thing exists conventionally (it is not nothing) but lacks inherent existence (svabhāva) — it has no nature of its own, independent of all other things.
