Nāgārjuna

Argued that nothing whatever has independent existence — including emptiness itself, which is the move that stops the whole thing collapsing into nihilism.

Who they were

Nāgārjuna, active around the second or third century CE in southern India, founded the Madhyamaka — the Middle Way school — and is, after the Buddha, the most important figure in Mahāyāna Buddhism.

He is also increasingly read in Western philosophy departments on his own terms, which is unusual for any figure on this site.

Where they came from

Almost nothing biographical is secure. Traditional accounts place him in the Sātavāhana period, associate him with Nāgārjunakoṇḍa, and report that he retrieved the Prajñāpāramitā sūtras from the nāgas, serpent-beings who had been guarding them until someone capable of understanding them appeared — a legend that neatly asserts the new literature's authority against the objection that it was not there before.

A later alchemical and medical Nāgārjuna is almost certainly a different person, or several.

His principal work is the Mūlamadhyamakakārikā — Fundamental Verses on the Middle Way — around 450 verses in twenty-seven chapters.

What they taught

Śūnyatā — emptiness. All phenomena lack svabhāva: inherent existence, own-being, the property of existing independently and in their own right.

This is not a claim that nothing exists. It is a claim about how things exist. Nothing has an independent essence, because everything arises in dependence on causes, conditions and parts. Nāgārjuna's decisive identification is that emptiness and dependent origination are the same thing said twice. To be empty is to be dependently arisen; to be dependently arisen is to be empty. That is why the position is a middle way — between saying things exist absolutely and saying they do not exist at all.

Two truths. Conventional truth — the world of tables, persons and traffic, which functions perfectly well and which Nāgārjuna does not deny. Ultimate truth — that none of it has inherent existence. Both are truths. Confusing them produces most of the misreadings.

His method is destructive, deliberately. He does not build a system; he takes the systems available — causation, motion, time, the self, the elements, the Buddha, nirvāṇa — and shows that each generates contradictions when the entities involved are treated as having inherent existence. The tetralemma structures the demolition: not X, not not-X, not both, not neither.

And then the move that makes it work. Chapter 13 turns the analysis on itself: emptiness is also empty. Emptiness is not a hidden true nature underlying appearances, not an absolute, not a substance. Anyone who takes emptiness as a thing, he says, is incurable — like someone told there is nothing in the shop who asks to be given some of that nothing.

Without that step the position becomes a metaphysics of the void, and Nāgārjuna spends real effort preventing it.

What we can and cannot say

We can say the influence is comprehensive. Madhyamaka became the philosophical foundation of Mahāyāna across East Asia and is the central philosophy of Tibetan Buddhism, where its interpretation is the subject of centuries of internal dispute.

We can say the nihilism reading is the standard misunderstanding and that he anticipated it explicitly. His answer is that nihilism and eternalism are both errors, and that his opponents keep hearing one because they cannot conceive of existence except as inherent existence.

We can say the connection to Śaṅkara is real and the difference matters. Both use two levels of truth; both treat the conventional world as dependently apparent. But Śaṅkara affirms a positive absolute — Brahman — and for Madhyamaka that affirmation is exactly what emptiness rules out. This is the sharpest philosophical disagreement in Indian thought and it was argued for a thousand years.

We can say Western philosophers now engage him seriously — Jay Garfield, Graham Priest and others have worked on the logic of the tetralemma and on whether his position is coherent or paraconsistent, and the discussion is live rather than antiquarian.

We cannot say whether the argument succeeds. It is genuinely difficult, and the honest position for a general reader is that a very large number of extremely careful people have found it compelling and a comparable number have found it self-undermining, for reasons that take years to assess.
