Position summary
Siderits’s signature programme is Buddhist Reductionism: the claim that Vaibhāṣika and Theravāda Abhidharma share with Derek Parfit a common philosophical move — persons are conceptual constructions, the explanatorily basic items are dharmas (or psychophysical elements), and personal identity is “all in the numbers” (causal/psychological connectedness, not a further fact). Madhyamaka, on Siderits’s reading, is not a rejection of this programme but its self-application: the further move that empties out the dharmas themselves, on the same grounds that emptied out the persons in the first place. He has spent his career articulating this as a sophisticated philosophical position rather than as a piece of historical reportage about Buddhism, hence his self-description as practising “rational reconstruction.”
Hermeneutical approach
Siderits is methodologically explicit: he is doing rational reconstruction, not philological recovery of “what Nāgārjuna meant.” This sets him apart from Kalupahana’s deflationary historical reading. He engages the Indo-Tibetan commentarial tradition (he refers to Vaibhāṣika, Theravāda, Madhyamaka by name, works with Sanskrit verses, and in siderits-buddhism-philosophy-2007 cites the Akutobhayā, Buddhapālita’s Buddhapālitavṛtti, Bhāviveka’s Prajñāpradīpa, and Candrakīrti’s Prasannapadā at parity), but the argumentative structure is analytic-philosophical: Parfit, Dennett, Strawson, Hume, Bradley, Putnam, Dummett are recurrent interlocutors. He is partly framework-engaging on two independent occasions: in siderits-reality-altruism-2000 (pp. 421–422) he reaches explicitly for the graded-teaching device (BCA 8 as provisional, BCA 9 as the prajñā-perfection corrective, with cross-reference to MMK 18:8) when Williams’s analytic critique would otherwise prevail; and in siderits-buddhism-philosophy-2007 (p. 206) he again endorses the graded-teaching reading of MMK 18:6 in the textbook-systematic exposition of MMK. The neyārtha / nītārtha device is therefore not a one-off defensive move but a structural feature of his Madhyamaka exposition. Significant for framework-absence-yields-nihilism: even an analytic Reductionist, when reading MMK carefully, finds the graded-teaching structure interpretively load-bearing.
The 2004 Journal of Indian Philosophy article (siderits-causation-emptiness-2004) is the cleanest counter-example to the framework-engaging tendency: a tightly focused technical reconstruction of MMK 1 against Hayes’s 1994 equivocation charge, conducted entirely at the Abhidharma–Madhyamaka technical level with Hume, Berkeley, Lewis-style possible-worlds semantics, and Bradley regress as analytic foils. Neyārtha / nītārtha, Two Truths-as-pedagogy, and the Three Turnings are absent from the article. The progression 2000 → 2004 → 2007 is therefore not monotonic on framework-engagement: framework-engaging in 2000 (BCA 8 / 9), framework-disengaged in 2004 (MMK 1 reconstruction succeeds at the narrow technical task), framework-engaging again in 2007 (MMK 18:6 + the systematic exposition). The pattern that emerges is task-relative — Siderits reaches for the graded-teaching device when the explanatory burden requires it, and stays at the technical level when the local task can be discharged without it. Important refinement for framework-absence-yields-nihilism (and for of this wiki): framework-removed readings can succeed at narrow technical reconstruction tasks; what they cannot do unaided is defend the full range of Madhyamaka claims (universal niḥsvabhāva, the no-thesis stance, the soteriological priority of emptiness).
Method is structurally Prāsaṅgika (Madhyamaka argument as reductio ad absurdum from the svabhāva-hypothesis, siderits-buddhism-philosophy-2007 p. 183) but Siderits does not engage the Prāsaṅgika–Svātantrika distinction, referring it only to Further Reading. He is framework-engaging at the formal-pedagogical level (Two Truths, graded teaching, commentarial-tradition citation) but not at the doctrinal level (Three Turnings, tathāgatagarbha, the Indo-Tibetan debates over the object of negation are absent). This places him alongside Westerhoff as the most framework-engaging of the modern analytic Madhyamikans, but framework-engaging differently — Westerhoff works through the Indo-Tibetan commentarial debates by name (especially in westerhoff-candrakirti-2024), Siderits absorbs the commentarial tradition into a unified analytic explanatory voice.
Key claims
- Persons are conventionally real because they are useful designations for utility-maximising causal series of psychophysical elements; ultimately unreal because the dharmas are explanatorily basic. (siderits-reality-altruism-2000 pp. 414–415)
- Maximal-causal-connectedness is the construction-recipe for persons; independently justified by the fact that systems with self-scrutiny / self-control / self-revision capacities are uniquely well-suited to local utility-maximisation. (siderits-reality-altruism-2000 pp. 417–418)
- Pains are subjectless at the ultimate level, conventionally subject-bearing. Williams’s adverbial / event analyses of pain are shown to undermine themselves once functionalism + multiple realisability are taken seriously. (siderits-reality-altruism-2000 pp. 418–420)
- The graded-teaching reading of BCA: chapter 8 (meditation-perfection) is provisional Reductionism; chapter 9 (prajñā-perfection) is the Madhyamaka corrective in which everything is equally empty. (siderits-reality-altruism-2000 p. 422; cf. MMK 18:8). Independently re-deployed at siderits-buddhism-philosophy-2007 p. 206 on MMK 18:6 (“the Buddha might teach non-self to some audiences, while he will teach others in a way that leads them to believe there is a self … there is thought to be a progression involved here”).
- Three interpretive options for emptiness — only the third is coherent. (siderits-buddhism-philosophy-2007 pp. 180–183) (a) metaphysical nihilism, (b) “reality is ineffable,” (c) semantic non-dualism. (a) is blocked by MMK V.6–8; (b) is blocked by MMK XIII.7–8 (the purgative simile); (c) is the only remaining live option and is what Nāgārjuna positively defends at MMK XXII.11 and XXIV.18 (emptiness of emptiness, prajñaptir upādāya).
- The two senses of “ultimate truth” disambiguation. (siderits-buddhism-philosophy-2007 pp. 202–203) “ultimate truth₁: a fact that must be grasped in order to attain full enlightenment; ultimate truth₂: a statement that corresponds to the ultimate nature of mind-independent reality.” The doctrine of emptiness then says “the ultimate truth₁ is that there is no ultimate truth₂.” Structurally close to what Tsongkhapa achieves with the bden grub qualifier, derived independently in analytic-philosophy idiom.
- Conventional truth as paper-currency-off-the-gold-standard. (siderits-buddhism-philosophy-2007 pp. 202–204) Truth without correspondence-grounding in things-with-svabhāva is no more incoherent than paper currency without gold backing — value (truth) derives from role in human practices. The analytic-philosophical reconstruction of how saṃvṛti can stand without paramārtha₂.
- Direct rebuttal of Burton/Hayes on the equivocation charge. (siderits-buddhism-philosophy-2007 pp. 192–195, fn. 5 names Burton 1999 pp. 90–94 and Hayes 1994) The MMK XV.1–2 argument considered in isolation does commit the equivocation between compounded₁ and compounded₂; but MMK I (causation) supplies the missing argument via three-times reasoning + Bradley regress on causal force. The combined argument blocks the equivocation charge. The full technical reconstruction of this rebuttal is the 2004 Journal of Indian Philosophy article (siderits-causation-emptiness-2004); the 2007 textbook is the absorbed re-statement.
- The causal relation itself is conceptually constructed (the 2004 reconstruction). (siderits-causation-emptiness-2004) MMK 1 establishes only that the causal relation is conceptually constructed, not that the relata are. The argument is two-staged: a Humean / three-times argument against any account of causation as obtaining at the level of ultimately-real impartite dharmas (MMK 1.5–7), supplemented by a Bradley regress against the asatkāryavādin’s recourse to a mediating causal force / kriyā (MMK 1.4). Bhāviveka anticipates Hume’s positive-projection account in his gloss on MMK 1.3 (Prajñāpradīpa, Pandeya 26): “parabhāva of the conditions is found due to intentness of the mind on the desire for what is productive of the arising of bhāva.” Note: Siderits is explicit (n. 35) that he reads MMK 1 less expansively than Hayes — the conclusion is that the relation is conceptually constructed, not that the relata are.
- Principle P (the 2004 article’s central new contribution). (siderits-causation-emptiness-2004 pp. 410–413) “If a relational tie is conceptually constructed, then any property of one of its relata that involves essential reference to that tie must likewise be conceptually constructed.” This is the bridge from “the causal relation is conceptually constructed” (the conclusion of MMK 1) to “the intrinsic nature of anything causally dependent is conceptually constructed” (the conclusion needed for the Madhyamaka niḥsvabhāva extension at MMK 15). The K2 / Sherlock Holmes counter-example is met by the essential-reference qualifier; the chariot-as-artefact example illustrates the principle’s operation. Principle P is not formulated by Nāgārjuna; it is Siderits’s reconstruction of the implicit principle Nāgārjuna would need.
- Translation insistence: svabhāva is “intrinsic nature,” not “self-existence” — and the criterion is realist. (siderits-causation-emptiness-2004 pp. 395–397) The “self-existence” rendering is the result of reading svabhāva through Madhyamaka uses alone without tracing it back to Abhidharma. Properly understood, the svabhāva criterion (only that with intrinsic nature is ultimately real) is a structural commitment of any non-conceptualist realism — what Vasubandhu and Berkeley share with Descartes and the Sautrāntikas, against subjective idealism’s denial of mind-independent natures. Convergent with Westerhoff’s threefold svabhāva analysis (essence-svabhāva / substance-svabhāva / absolute svabhāva) but reached independently via the Abhidharma route.
- The “everything-depends-on-everything” interpretation is blocked by Nāgārjuna himself. (siderits-buddhism-philosophy-2007 pp. 200–202, on MMK XV.3) “There can be no extrinsic nature without intrinsic nature.” The metaphysical-interconnectedness reading is therefore not an option; pratītyasamutpāda must be read at the conventional level only.
- Madhyamaka’s universal emptiness is coherent — but the full defence is held back: at siderits-reality-altruism-2000 fn. 10, p. 423 (“this difference need not concern us here”); the textbook-systematic statement at siderits-buddhism-philosophy-2007 is the working-out of that defence.
Related scholars
- Williams — Siderits’s principal interlocutor in siderits-reality-altruism-2000; the two are positioned at opposite poles on whether Madhyamaka’s extension of niḥsvabhāva to the dharmas is coherent (Siderits: yes; Williams: no).
- Westerhoff — fellow contemporary analytic Madhyamikan; cites Siderits approvingly on “semantic insulation” between the two truths in westerhoff-candrakirti-2024 (MA 6:031). Both are framework-engaging but constructive-antirealist rather than commentarial.
- Kalupahana — methodologically opposite framework-revisionist: where Kalupahana flattens the Two Truths and rejects Mahāyāna systematisation, Siderits keeps the Two Truths hierarchical and treats Madhyamaka as a rigorous philosophical system.
- Burton — Buddhist Reductionism without the Madhyamaka extension yields Burton’s regress-from-universal-prajñaptimātra. Siderits accepts the extension and so avoids the regress but has not yet (in this source) shown how.
- Oetke — different idiom, similar question. Both rationally reconstruct Madhyamaka in analytic terms; Oetke’s “on the level of highest truth there is nothing of any kind” is more austere than Siderits’s defence-in-fn-10 of Madhyamaka coherence.
