retrofuturist wrote:What is the doctrine of the two truths?
From the Manorathapūraṇī:
duve saccāni akkhāsi
sambuddho vadataṃ varo
The Awakened One, best of speakers,
Spoke two kinds of truths:
The conventional and the ultimate.
A third truth does not obtain.
dhammānaṃ tathalakkhaṇan ti
The speech wherewith the world converses is true
On account of its being agreed upon by the world.
The speech which describes what is ultimate is also true,
Through characterizing dhammas as they really are.
musāvādo na jāyatī ti
Therefore, being skilled in common usage,
False speech does not arise in the Teacher,
Who is Lord of the World,
When he speaks according to conventions.
(Mn. i. 95)
Conventional truth (sammuti-sacca):
1. Treats of concepts (paññatti), i.e., things which are mere speech, such as 'self', 'person', 'life', 'butter-jar' etc.
2. Is used to expound teachings whose meaning warrants interpretation (neyyattha).
3. Is chiefly, though not exclusively, the province of the Sutta and Vinaya Piṭakas.
Ultimate truth (paramattha-sacca):
1. Treats of real existents (dhammā), such as the earth element, eye-consciousness, greed, Nibbāna, etc.
2. Is used to expound teachings whose meaning is definitive (nītattha).
3. Is chiefly, though not exclusively, the province of the Abhidhamma Piṭaka.
From Nyanatiloka's Dictionary of Buddhist Terms
Paramattha (-sacca, -vacana, -desanā): ‘truth (or term, exposition) that is true in the highest (or ultimate) sense’, as contrasted with the ‘conventional truth’ (vohāra-sacca), which is also called ‘commonly accepted truth’ (sammuti-sacca; in Skr: saṃvṛti-satya). The Buddha, in explaining his doctrine, sometimes used conventional language and sometimes the philosophical mode of expression which is in accordance whith undeluded insight into reality. In that ultimate sense, existence is a mere process of physical and mental phenomena within which, or beyond which, no real ego-entity nor any abiding substance can ever be found. Thus, whenever the suttas speak of man, woman or person, or of the rebirth of a being, this must not be taken as being valid in the ultimate sense, but as a mere conventional mode of speech (vohāra-vacana).
It is one of the main characteristics of the Abhidhamma Piṭaka, in distinction from most of the Sutta Piṭaka, that it does not employ conventional language, but deals only with ultimates, or realities in the highest sense (paramattha-dhammā). But also in the Sutta Piṭaka there are many expositions in terms of ultimate language (paramattha-desanā), namely, wherever these texts deal with the groups (khandhā), elements (dhātu) or sense-bases (āyatana), and their components; and wherever the 3 characteristics (ti-lakkhaṇa, q.v.) are applied. The majority of Sutta texts, however, use the conventional language, as appropriate in a practical or ethical context, because it “would not be right to say that ‘the groups’ (khandhā) feel shame, etc.”
It should be noted, however, that also statements of the Buddha couched in conventional language, are called ‘truth’ (vohāra-sacca), being correct on their own level, which does not contradict the fact that such statements ultimately refer to impermanent and impersonal processes.
The two truths - ultimate and conventional - appear in that form only in the commentaries, but are implied in a sutta-distinction of ‘explicit (or direct) meaning’ (nītattha, q.v.) and ‘implicit meaning (to be inferred)’ (neyyattha). Further, the Buddha repeatedly mentioned his reservations when using conventional speech, e.g. in D. 9: “These are merely names, expressions, turns of speech, designations in common use in the world, which the Perfect One (Tathāgata) uses without misapprehending them.” See also S. I. 25.
The term paramattha, in the sense here used, occurs in the first para. of the Kathāvatthu, a work of the Abhidhamma Piṭaka (s. Guide, p. 62). (App: vohāra). The commentarial discussions on these truths (Com. to D. 9 and M. 5) have not yet been translated in full. On these see K N. Jayatilleke, Early Buddhist Theory of Knowledge (London, 1963).
Sammuti-sacca: ‘conventional truth’, is identical with vohāra-sacca (s. paramattha-sacca).
Vohāra-desanā: ‘conventional exposition’, as distinguished from an explanation true in the highest sense (paramattha-desanā, q.v.). It is also called sammuti-sacca (in Sanskrit saṃvṛti). (App.).
