Dharmakirti
A Chinese monk named Yijing walked the halls of Nalanda between 675 and 685 CE. He spoke of a teacher called Dharmakirti as someone recent to his time. This single detail anchors the philosopher in the middle of the seventh century. No other biographical facts survive with such certainty from that era. The Telhara monastery stood just a short distance away from Nalanda. A traveler named Wuxing studied Dharmakirti's teachings there around 650 or 660 CE. His fame as a logician had reached Magadha by then. Tibetan stories claim he was born into a Brahmin family in South India. They say his uncle Kumārila Bhaţţa spoke abusively to him over robes. These hagiographies remain uncertain to modern scholars who place him later than the legends suggest.
Dharmakirti defined a pramāņa as a reliable cognition in his text Pramāņavarttika 2.1ac. He argued reliability consists in compliance with an object's capacity to perform a function. Perception serves as a non-conceptual knowing bound strictly by causality. Inference operates through reasonable, linguistic, and conceptual means. Smoke must always be present when fire is present for inference to hold true. This evidence requirement provided a stronger foundation for reasoning than before. Dignaga left this problem unresolved until Dharmakirti refined it. Scripture holds no claim to certainty according to his view. One should not use scripture to guide matters decided by factual rational means. Only radically inaccessible things like karma laws require scriptural reliance. A yogi's inconceivable perception stands as another extraordinary epistemic warrant alongside the Buddha's words.
Whatever has causal powers exists as real according to Dharmakirti's statement. He rejected universals because they possess no causal efficacy or power. Real particulars called svalakşana are part-less and undivided yet impart force. These particulars give rise to perceptual cognitions that reflect them directly. Language never describes things in themselves but only conceptual fiction. Words talk about entities qualified by the negation of other things. This theory of exclusion underlies his entire philosophical system. Cognitive distortion occurs during recognition when latent tendencies arise from past impressions. Ignorance overlays conceptuality upon naturally radiant pure perception. Correcting these defilements allows a Buddhist yogi to see reality better. Nothing could be a cause while remaining the same thing forever.
An act of intentional consciousness is aware of itself as aware. Consciousness illuminates itself just as a lamp lights objects in a room. External objects do not exist outside the act of cognition itself. An object is necessarily experienced simultaneously with the cognition according to Pramāņavarttika 3.387. Duality between an object and subjective cognition arises out of ignorance. The mindstream flows as a beginningless temporal sequence without true endings. No true beginnings exist within this continuous stream of awareness. Dharmakirti defended the Yogacara theory of awareness-only against external realism. His treatise on the nature of mindstreams addresses the problem of other minds. He held that the mindstream possesses no true start or finish point.
Dharmakirti wrote the largest work known as the Pramāņavarttika-kārika. This text became central to studies in monasteries across Tibet today. Other major works include the Nyāyabinduprakaraņa and the Hetubindunāmaprakaraņa. Devendrabuddhi commented on his writings around 675 CE while Sakyabuddhi did so near 700 CE. Phya pa Chos kyi Seng ge wrote a summary called Clearing of Mental Obscuration with Respect to the Seven Treatises on Valid Cognition between 1182 and 1251. Sakya Pandita authored the Treasure on the Science of Valid Cognition later. These two interpretations formed the foundation for most debates in Tibetan epistemology. Later Indian scholars like Karňakagomin and Prajñakaragupta also produced commentaries. The earliest commentators remain Devendrabuddhi and Sakyabuddhi from the seventh century.
His texts remain part of studies in the monasteries of Tibetan Buddhism today. Dharmakirti's theories became normative within that tradition over centuries. Scholars place him in the middle of the seventh century based on textual citations. Adi Shankara cited Dharmakirti verses during the collapse of the Gupta Empire. His ideas influenced Hindu schools including Mīmāmsā, Nyaya, and Shaivism as well. Jainism scholars also engaged with his arguments against Brahminical views. The Gelug school asserts he expressed Yogacara views while others claim Sautrantika perspectives. Dan Arnold argues his alternating philosophical perspectives apply at different levels of analysis. Modern doxographers disagree on how to categorize his thoughts entirely. He lived during a time of great insecurity for Buddhist institutions facing polemics.
