Definition
Emptiness (śūnyatā) is the central doctrine of Madhyamaka philosophy: all phenomena are empty of intrinsic nature (svabhāva). This does not mean non-existence but rather that nothing possesses independent, self-sustaining existence. Everything arises dependently (pratītyasamutpāda). As Candrakīrti states in his commentary on MMK 24:7, the meaning of “dependent origination” is precisely the meaning of “emptiness” — but the meaning of “non-existence” is not the meaning of “emptiness.”
The emptiness of emptiness (śūnyatāśūnyatā) is a crucial refinement: emptiness itself is not a substantial, ultimately real property — it too is empty. This prevents emptiness from becoming a reified metaphysical view (dṛṣṭi), as Nāgārjuna warns in MMK 13:18.
Interpretations
Westerhoff’s “emptiness as conventional corrective”: Westerhoff in westerhoff-madhyamaka-2009 argues that the theory of emptiness is not an ultimately true description of mind-independent reality. Its purpose is to combat the wrong ascription of svabhāva to phenomena — a corrective for a mistaken cognition. The analogy: an empty pot does not normally need to be described as “free of white mice,” but if someone hallucinates mice on it, this negative description becomes useful. Without the error, the corrective is unnecessary. Emptiness therefore does not exist “from its own side” and is not causally produced with its object (unlike the empty space in a cup). A mind not prone to the svabhāva-superimposition would have no need to conceive of objects as empty. This entails the rejection of correspondence truth in favour of truth as warranted assertibility: there can be no “ultimate truth” describing how things really are independent of conceptual frameworks. Even emptiness is only conventionally true (pp. 44–45, 219–222). This position sits close to the Geluk mainstream but draws out implications that traditional commentators leave implicit.
Nihilist readings: Some interpreters — from non-Buddhist Indian critics (Uddyotakara, Kumārila, Śańkara) through Yogācāra critics (Asańga, Vasubandhu) to modern scholars (Burton, Wood, early de la Vallée Poussin) — have understood emptiness as equivalent to non-existence (abhāva), producing a nihilist reading of Madhyamaka. Westerhoff in westerhoff-nihilist-interpretation-2016 argues this charge points to real features of the system but fails when it takes nihilism to entail denial of appearances, denial of efficacy, or moral nihilism.
Siderits’s three-options taxonomy and semantic non-dualism: In siderits-buddhism-philosophy-2007 Ch 9 (pp. 180–207), Mark Siderits gives a systematic analytic-philosophical taxonomy of interpretive options once Madhyamaka arguments are granted: (a) metaphysical nihilism — “ultimately nothing whatever exists”; (b) “reality is ineffable” — what is ultimately real transcends conceptual capacity (Yogācāra adopts a variant); (c) semantic non-dualism — the very idea of an ultimate truth (in the Abhidharma correspondence-theoretic sense) is incoherent. (a) is blocked by Nāgārjuna’s own argument at MMK V.6–8 (“when the existent is not real, with respect to what will there come to be non-existence?”); (b) is blocked by MMK XIII.7–8 (the purgative simile: “those for whom emptiness is a [metaphysical] view, they have been called incurable”); (c) is the only remaining live option and is positively supported by the emptiness-of-emptiness verses MMK XXII.11 and XXIV.18 (prajñaptir upādāya). The apparent paradox of “the ultimate truth is that there is no ultimate truth” is dissolved by disambiguating two senses: ultimate truth₁ = a fact that must be grasped to attain enlightenment; ultimate truth₂ = a statement corresponding to the ultimate, mind-independent nature of reality. The doctrine of emptiness then reads “the ultimate truth₁ is that there is no ultimate truth₂.” Conventional truth survives without correspondence-grounding via this wiki-currency-off-the-gold-standard analogy: value (truth) derives from role in human practices, not from backing by intrinsically natured items. Significance: semantic non-dualism is a fourth substantive reading distinct from Tsongkhapa’s med dgag of bden grub, Gorampa’s two-level ultimate, Westerhoff’s deflationary antirealism, and the early-Western deflationary line (Sprung 1979 / Kalupahana 1986 / Burton 1999). Closest to Sprung’s Wittgensteinian “the higher truth, in so far as it is a theory, falls within the lower truth,” but unlike Sprung explicitly defeats both nihilist and ineffabilist readings via Nāgārjuna’s own arguments rather than by a Wittgensteinian language-game move.
Burton’s nihilism argument: Burton in burton-emptiness-appraised-1999 provides the most sustained modern case for the nihilist reading. He argues that, understood in the Abhidharma context, universal absence of svabhāva means all entities are entirely conceptually constructed (prajñaptimātra). Conceptual construction requires both unconstructed material and an unconstructed constructor. Since Nāgārjuna denies any unconstructed existent, nothing can exist. Burton acknowledges Nāgārjuna did not intend nihilism, but argues his philosophy entails it. He further argues that even on a non-nihilist reading, Nāgārjuna’s equation of analysable existence with conceptually constructed existence is “excessive ontological parsimony.” The dGe lugs pa solution (emptiness is true but does not truly exist) is acknowledged as “the most ingenious attempted solution” but not fully engaged because Burton’s method excludes later commentarial elaboration.
Candrakīrti’s position: In the Prasannapadā on MMK 18:7, Candrakīrti concedes an “essential identity” (vastutas tulyatā) between what the Mādhyamika and the nihilist say about what does not exist — but insists on a vast epistemological and soteriological difference between the proponents. The “theft” analogy: two men say the same thing (“he is a thief”) but one speaks from knowledge, the other from malice.
Garfield’s emptiness of emptiness (FWMW, framework-internal): In garfield-fundamental-wisdom-1995, Garfield makes the emptiness of emptiness the architectural key to the whole MMK, “harmonizing with Candrakīrti’s” reading and present already in the opening chapter on conditions, only made explicit at 24:18. Emptiness is “not a self-existent void standing behind a veil of illusion comprising conventional reality, but merely a characteristic of conventional reality.” His worked demonstration (24:18 commentary): analyse the emptiness of a table and “we find nothing at all but the table’s lack of inherent existence… the emptiness is dependent upon the table and is therefore itself empty, as is the emptiness of that emptiness, and so on, ad infinitum.” The apparent regress is rendered harmless by Madhyamaka nominalism: “conventional” functions ontologically (a mode of subsistence), not as a logical negation-operator that would cancel itself — so the iteration does not collapse into “really, things are non-empty.” This is what saves the system “from falling into metaphysical extravagance.” Emptiness is wholly negative (Ch XIII): “not an essence that things have instead of whatever essence… they were thought to have — rather, it is the total lack of essence.” And it is emphatically anti-nihilist via the twin-distortion thesis (24:16): “nihilism about one kind of entity is typically paired with reification of another” — reifying the conventional requires reading emptiness nihilistically; reifying emptiness requires nihilism about the phenomenal world. Garfield’s reading converges with Tsongkhapa’s śūnyatāśūnyatā (above) and Candrakīrti’s, reached in the analytic register. The architecture is stated a year earlier, and as an explicit reading-method, in garfield-dependent-arising-1994: the emptiness of emptiness is “in embryo” in MMK Ch 1 (which is why Nāgārjuna opens with causation), and one must read Ch 1 through Ch 24, holding the emptiness of emptiness in mind, for the negations to read as self-consuming rather than nihilistic — “it is one thing to argue for the emptiness of some phenomenon simpliciter and quite another to argue for that emptiness with the emptiness of emptiness in mind.” His worked example is the motion chapter (MMK 2): read alone it “can appear unrelentingly nihilistic”, but read with the emptiness of emptiness imported from Ch 24, motion is recovered as a merely conventional, dependent relation. Tension flagged: his heavy Tractatus gloss on the apophatic verses (18:9) sits near Sprung’s reading; cite him for the self-consuming negation, not for the anti-quietism guardrail.

- Early Pāli-canonical loci of suññatā (catalogued in chowdhury-nagarjuna-hermeneutics-2018): Cūḷa-suññata Sutta MN 121 — suññatā as meditative dwelling (suññatā-vihāra); Mahā-suññata Sutta — the world is empty of self or anything pertaining to a self (suññam idaṁ attena vā attaniyena vā); Āneñjasappāya Sutta MN 106 — suññāgāra, an “empty place” as the locus for mindful breathing; Mahāvedalla Sutta MN 43 — suññatā-cetovimutti, “release of mind through emptiness.” This pre-Madhyamaka stratum frames śūnyatā as a meditative-soteriological notion, not yet as the universal anti-substance argument it becomes in the MMK. Karunadasa (karunadasa-theravada-abhidhamma-2010 Introduction p. 8; Ch 1 p. 40) reads the same stratum doctrinally: the world is empty “of self or of anything pertaining to a self” (attena vā attaniyena vā suññaṃ), so that “empty” (suñña) and “non-self” (anattā) are “mutually convertible expressions” — licensing the restatement of sabbe dhammā anattā as sabbe dhammā suññā. On this Theravāda reading suññatā is anchored to anattā and does not, of itself, extend to a universal niḥsvabhāva of all phenomena — the scope-difference this wiki flags at /
