Dharmakirti
Perception and inference are the only valid means of knowledge — the most rigorous Buddhist epistemology, dismantling Brahmanical authority and the permanent self
Dharmakirti was an Indian Buddhist philosopher, probably active in the late sixth or seventh century CE, who became the most important logician and epistemologist in the Buddhist tradition. Building on the foundations laid by Dignaga (c. 480–540), he composed the Pramanavarttika (Commentary on Valid Cognition), a vast and technically demanding work that became the standard Buddhist textbook on logic and epistemology for centuries, studied intensively in both Indian and Tibetan Buddhist monastic universities. Dharmakirti's system recognises only two valid means of knowledge (pramana): perception (pratyaksha) and inference (anumana). He deploys this austere epistemology to dismantle Brahmanical claims to the authority of the Vedas, the reality of a permanent self (atman), and the existence of a creator God (Ishvara). His logical innovations — including the theory of "natural reason" (svabhavahetu), the apoha (exclusion) theory of meaning, and the doctrine of momentariness (ksanikavada) — represent the high point of Indian Buddhist philosophical rigour.

Dharmakirti's epistemology is in service of Buddhist soteriology: valid cognition is important because it leads to correct understanding of suffering, impermanence, and no-self, which is the path to liberation. The Buddha himself is a valid authority (aptapurusha) because his teachings are verified by perception and inference.
"The purpose of valid cognition is the attainment of human ends (purushartha); therefore the investigation of the means of valid cognition is worthwhile." (Pramanavarttika I, opening verse, paraphrase)
Dharmakirti's two-pramana system (perception and inference alone) is a radically rationalist epistemology that rejects testimony (shabda), analogy (upamana), and all other pramanas accepted by Brahmanical schools. Knowledge must be grounded in direct acquaintance or rigorous logical derivation.
"There are only two means of valid cognition — perception and inference — because there are only two kinds of objects: the particular and the universal." (Pramanavarttika, paraphrase)
While Dharmakirti is primarily associated with the Yogacara-Sautrantika synthesis, his denial of the permanent self and his analysis of causation as momentary events share common ground with Madhyamaka's rejection of intrinsic nature (svabhava). Tibetan scholasticism studied him alongside Nagarjuna as a complementary Buddhist authority.
"Whatever is produced is momentary." (Pramanavarttika, ksanikavada argument)
Dharmakirti's epistemology has strong Yogacara affinities: the svalakshana (unique particular) that is the object of perception is a momentary mental event, and conceptual construction (vikalpa) is the mind's own activity. Some scholars classify him as Yogacara-Sautrantika.
"Perception is free from conceptual construction and is non-erroneous." (Pramanavarttika, pratyaksha chapter, paraphrase)
Modern analytic philosophers have found striking parallels between Dharmakirti's apoha (exclusion) theory of meaning and Fregean-Russellian theories of reference and predication. His logical rigour invites comparison with Western formal logic.
"A word designates its referent not by denoting a positive universal but by excluding what is other." (Apoha theory, Pramanavarttika, paraphrase)
Dharmakirti's insistence that perception of the unique particular (svalakshana) is the foundation of all valid cognition has been compared to British empiricism's emphasis on sense-data as the basis of knowledge.
"Only the unique particular is ultimately real; the universal is a mental construction." (Pramanavarttika, paraphrase)
Internal Tensions
Dharmakirti's central tension is between his radical momentariness — nothing endures across moments — and the practical requirements of his own system. If each moment is entirely distinct, how can inference, which connects premises to conclusions across time, be valid? How can the Buddha's authority, established in the past, ground present practice? His theory of "natural connection" (svabhavapratibandha) between reason and conclusion is meant to solve this, but critics (Kumarila Bhatta, Udayana) argued it was parasitic on the very enduring universals he denied. The apoha theory of meaning faces the objection that exclusion presupposes the positive entities being excluded.
I. Time
Infinite — the cycle of samsara has no beginning. Time is relational and discrete: Dharmakirti's doctrine of momentariness (ksanikavada) holds that each moment is a distinct, real event; there are no enduring substances across moments. Deterministic: each moment is caused by the preceding moment through strict causal regularity (niyama); there is no room for uncaused events or libertarian free will.
Attributes
II. Space
Infinite and relational. Space, like time, is constituted by the relations among momentary dharmas. Local: causal efficacy requires spatiotemporal contiguity.
Attributes
III. Matter
Finite, emergent, non-conserved. Material objects are conventional designations for streams of momentary events. Nothing endures across moments; hence "conservation" does not apply. Matter is emergent — it appears as a construction from more basic momentary constituents.
Attributes
IV. Observer
Embodied, single-instance, active. The observer is a stream of momentary cognitive events, not a permanent self. Knowledge is immediate in perception (pratyaksha) but fallible in inference (subject to logical error). Active agency: the philosopher must rigorously investigate the means of valid cognition. No metaphysical agency: there is no creator God or cosmic self.
Attributes
V. Energy
Unaddressed in modern terms. Dharmakirti's causal theory is a theory of momentary causal efficacy (arthakriya), not a theory of conserved energy. Relational: causal power is a feature of the momentary particular, not a substance that persists.
Attributes
VI. Information
Relational and non-conserved. Knowledge is a momentary cognitive event that arises and perishes. There is no permanent knower who retains knowledge across moments. The apoha theory treats conceptual content as negative (exclusion of the other) rather than a positive substance. Personal information is non-conserved because there is no permanent self to conserve it.
