Nagarjuna and the Philosophy of Emptiness

By Tim Yu · Updated 2026-06-04

Nagarjuna (flourished 2nd century CE) is the most influential Buddhist philosopher after the Buddha himself — the founder of the Madhyamaka, or “Middle Way,” school, and the thinker who gave the teaching of emptiness its rigorous philosophical form. His relentless arguments that nothing possesses inherent existence reshaped the whole of Mahayana Buddhism, and his influence has never faded.

The short answer

Encyclopaedia Britannica describes Nagarjuna as an Indian Buddhist philosopher who “flourished 2nd century ce,” whom “scholars generally place… in South India,” and who is “traditionally regarded as the founder of the Madhyamika (‘Middle Way’) school, an important tradition of Mahayana Buddhist philosophy.” His towering achievement was to articulate “the doctrine of emptiness (shunyata)” — which, crucially, “is not the absence of existence but the absence of intrinsic existence.” In his masterwork, the Mulamadhyamakakarika (“Fundamental Verses on the Middle Way”), he turned the bare declarations of the Perfection of Wisdom scriptures into a complete philosophical system. Britannica’s summary is unequivocal: Nagarjuna is “the most famous thinker in the history of Buddhism after the Buddha himself.” (Unfamiliar terms are in the glossary.)

In more depth

The philosopher behind emptiness

Some teachings are inseparable from the mind that shaped them, and the Buddhist doctrine of emptiness is bound up with Nagarjuna. The Perfection of Wisdom (Prajñāpāramitā) scriptures had proclaimed that all things are empty — but they proclaimed it rather than argued it. Nagarjuna’s genius was to take that proclamation and forge it into philosophy: to show, by rigorous reasoning, why nothing can possess independent existence, and to defend that conclusion against every objection. In doing so he set the intellectual course of the entire Mahayana for the next two thousand years.

His life: history and legend

About the man himself, history is thin and legend is thick — as so often with the great figures of ancient India. What scholars can say with confidence is small: that he lived around the 2nd century CE and worked in South India. Around that slender historical core the tradition wove rich legends — most famously that he received the Perfection of Wisdom scriptures from the nāgas, the serpent-beings of the deep, who had guarded them beneath the sea until the world was ready; some accounts also credit him with feats of alchemy and an immensely long life. A trustworthy account simply marks the line between the two: a brilliant philosopher of the 2nd century, around whom later devotion gathered a halo of marvels.

The Madhyamaka: the Middle Way school

The school Nagarjuna founded is the Madhyamaka, “the Middle Way.” The name reaches back to the Buddha’s own middle way, but Nagarjuna sharpens it to a precise philosophical point: the middle between the two great metaphysical extremes of eternalism — the belief that things truly and independently exist — and nihilism — the belief that nothing exists at all. Both, he argues, are mistakes, and emptiness is the path between them. As Britannica notes of his school (which it also calls the Śūnyavāda, the “Doctrine That All Is Void”), Nagarjuna “developed the doctrine that all is void.” This is simply the Buddha’s teaching of dependent origination carried to its logical conclusion: because everything arises in dependence on conditions, nothing exists on its own — and that is what emptiness means.

The doctrine: empty of intrinsic existence

The single most important thing to grasp about Nagarjuna’s emptiness is what it does not mean. It is not the claim that nothing exists. As Britannica puts it, “emptiness… is not the absence of existence but the absence of intrinsic existence.” Things are real enough to appear, to function, to matter — but none of them is a fixed, self-standing essence (svabhāva) that exists “from its own side.” Look for such an essence in anything — a chariot, a self, a moment of time — and you find only a web of parts, causes, and concepts. To be empty is precisely to be dependent; and to be dependent is precisely to be empty. Emptiness, for Nagarjuna, is not a bleak void but the open, fluid, interdependent nature of everything that is.

The method: arguing by consequence

Nagarjuna’s way of arguing is as distinctive as his conclusion. He rarely asserts a positive thesis of his own; instead he takes up an opponent’s position — that things have inherent existence — and patiently shows that it collapses into contradiction. Britannica describes the method exactly: he examines entities to “show that none of them is tenable because of the absurdities that would be entailed.” Category by category — causation, motion, the self, time, even nirvana itself — he demonstrates that inherent existence cannot be coherently maintained. The aim is not clever destruction for its own sake but release: to pry the mind loose from its instinctive grasping at fixed essences. Nagarjuna even turns this on emptiness itself, warning that emptiness too must not be clung to as one more thing that “really exists” — it is a raft, not a resting place.

The two truths

To keep all this from sliding into nihilism, Nagarjuna draws a famous distinction between two truths. On the level of conventional truth, the everyday world is exactly as it seems: chariots carry, fire burns, people are born and die, and the Buddhist path can be taught and walked. On the level of ultimate truth, all these things are empty of inherent existence. Both truths are indispensable: without the conventional, nothing could be communicated or practised; without the ultimate, no one could be liberated. Emptiness does not erase the ordinary world — it reveals its true, dependent nature, and so frees us from clinging to it.

Nirvana and samsara

From all this Nagarjuna draws a conclusion that can take the breath away: since all things are empty, there is no ultimate gulf between samsara, the round of suffering, and nirvana, liberation. They are not two separate realms, one to be fled and the other reached. Nirvana, on his account, is samsara seen rightly — this very world, emptied of the grasping at inherent existence that turned it into bondage. Freedom is not an escape to somewhere else but a clear seeing of where we already are. It is a vertiginous idea, and a deeply practical one: it places liberation not in another life or another place, but in the transformation of how we see this one.

His enduring influence

Few thinkers in any tradition have cast so long a shadow. Nagarjuna’s philosophy of emptiness became the foundation of nearly all later Mahayana thought: it runs through the Heart Sutra’s declaration that “form is emptiness,” through Zen’s pointing beyond all fixed views, and through the Tibetan traditions, where Madhyamaka remains the highest philosophical view to this day. For all the formidable difficulty of his logic, his purpose was finally simple and compassionate — the Buddha’s own purpose: to loosen the grasping at fixed, independent existence that lies at the root of suffering, and so to set the mind free.
