Nagarjuna

Methodology

Nāgārjuna reasons by relentless application of the catuskoti (tetralemma) and prasanga (consequentialist reduction to absurdity), interrogating every candidate thesis — P, not-P, both P and not-P, neither P nor not-P — and showing that none can be held without self-contradiction when the thesis asserts inherent, independent existence (svabhāva). The method is not the construction of a rival metaphysical system but the systematic dismantling of all systems that reify phenomena. By following out the consequences of any claim to fixed, self-sufficient being, Nāgārjuna discloses śūnyatā (emptiness): all dharmas are empty of svabhāva, arising only in dependence on conditions (pratītyasamutpāda). Crucially, emptiness is itself empty — it is not a new absolute, not a nihilistic void, and not a mystical plenum. The two-truths doctrine (saṃvṛti-satya, conventional truth, and paramārtha-satya, ultimate truth) holds these levels in non-collapsing tension: conventional designations function and matter, while ultimately nothing bears its own existence from its own side. Nāgārjuna's dialectic refuses the two extremes his tradition called eternalism (śāśvatavāda — things truly and permanently exist) and nihilism (ucchedavāda — things do not exist at all). The middle is not a compromise midpoint but the dissolution of the very binary that generates the extremes. His reasoning is therapeutic as much as logical: the purpose is the uprooting of grasping (upādāna) and the cognitive distortions (kleśa) that arise when the mind mistakes conventional designations for self-sufficient realities. Understanding arises not by reaching a correct positive doctrine but by releasing attachment to any fixed view (dṛṣṭi), including attachment to emptiness itself.

Sample argument

Consider motion. If a thing moves, where does movement reside — in what has already been traversed, in what has not yet been traversed, or in the very act of traversing? What has been traversed is past and contains no current moving. What has not been traversed is not yet engaged and contains no current moving. And a third locus — 'the traversing itself' — is simply posited without any ground; it collapses back into the first two. So there is no mover, no moved, and no moving that can be established as inherently real. Yet we do not deny that people walk from place to place; conventional designation of motion functions and serves practical purposes. The error lies not in using the word 'motion' but in supposing that behind the designation there is some self-sufficient thing called 'motion' bearing its own being. When that supposition is released, motion is seen as dependently arisen — neither absolutely real nor absolutely unreal. This is not a conclusion one holds; it is a loosening of the grip that mistook a designation for a thing.

Topics

• The Self — The self (ātman) has no svabhāva; it is a conventional designation applied to a stream of dependently arising aggregates. This is not nihilism about persons — persons function conventionally — but it forecloses any essentialist account of personal identity that would ground grasping or fear of annihilation.
• Ethics — Emptiness does not dissolve ethics; compassion and virtuous conduct remain obligatory at the conventional level. The Ratnāvalī addresses a king on the cultivation of virtue and the bodhisattva ideal, showing that Nāgārjuna regarded ethical practice as inseparable from philosophical understanding.
• Epistemology — Nāgārjuna holds that all objects of knowledge are empty of inherent existence and arise only in dependence on conditions and conceptual designations. Knowledge claims function at the conventional level but no claim accesses a self-sufficient reality. The tetralemma exhausts and dismantles every candidate epistemic position.
• Religion — Nāgārjuna presents his analysis as a rigorous explication of the Buddha's teaching of pratītyasamutpāda and the Middle Way, situating the Madhyamaka dialectic within the soteriological project of the Dharma rather than as independent metaphysics. Liberation depends on correctly understanding emptiness.
• Scientific Method — The prasanga method — deriving an absurd or contradictory consequence from an opponent's thesis — parallels reductio reasoning in formal argument. Nāgārjuna's exhaustive interrogation of causal, temporal, and mereological claims anticipates concerns later treated in analytic metaphysics and philosophy of science, though his aims are soteriological rather than scientific.
