The particulars of his life are known mainly through later tradition and the testimony of his works and commentators, and are treated with appropriate care. Dharmakirti is thus remembered chiefly as a philosopher of the first rank, whose systematisation of Buddhist logic and epistemology shaped the course of later Indian and Tibetan thought.

How Did Dharmakirti Build on Dignaga?

Dharmakirti built upon the foundations laid by Dignaga, the founder of Buddhist logic, by developing, refining and systematising the study of logic and epistemology that Dignaga had established. Dignaga had given systematic form to the Buddhist study of the valid means of knowledge, and Dharmakirti took up this tradition, extending and deepening it in his own works. He is remembered for clarifying, elaborating and in some respects reshaping the teachings he inherited, giving the tradition its most influential form. His relationship to Dignaga is often compared to that of a great successor who perfects the work of a founder. Through this development, the Buddhist study of logic reached its height. Out of respect, the teachings are described here only in general terms. Dharmakirti’s building upon Dignaga is central to his importance, for he carried the tradition of Buddhist logic to its fullest development. He is thus remembered as the thinker who brought the school founded by Dignaga to its most refined and influential form.

What Is the Pramanavarttika?

The Pramanavarttika is the major work of Dharmakirti, a foundational treatise on logic and epistemology that developed and systematised the study of the valid means of knowledge within the Buddhist tradition. The work is understood in the tradition as an extended examination and elaboration of the study of logic founded by Dignaga, and it became the most influential text of the Buddhist logical tradition. Through the Pramanavarttika, Dharmakirti gave the study of logic and epistemology its most refined form, treating such matters as perception, inference and the testing of knowledge. The work is counted among the most important treatises of Indian philosophy and had a profound influence on later thought, both within the Buddhist tradition and beyond. Out of respect, its doctrinal and philosophical content is described here only in general terms. The Pramanavarttika secured Dharmakirti’s standing as the master of Buddhist logic. It thus stands as a monument of the Buddhist intellectual tradition and as the central text of its study of logic and the means of knowledge.

When Did Dharmakirti Live?

Dharmakirti is traditionally placed around the sixth to seventh centuries, though the exact span of his life is uncertain and rests largely on later tradition and the testimony of the works associated with him. The dating of early philosophers of the subcontinent is often reconstructed from later accounts, from references in the works of commentators and from the wider history of the period, rather than from precisely documented records. For this reason, the dating of Dharmakirti is best understood as a broadly held tradition supported by such evidence, and scholars treat the particulars with due caution. He is understood to have lived some generations after Dignaga, whose work he developed. What is clear is that he belongs to a flourishing period of philosophical inquiry, when the intellectual traditions of the subcontinent engaged in vigorous debate. The uncertainty surrounding his precise dates does not diminish his standing as the master of Buddhist logic. Dharmakirti is therefore remembered as a philosopher of the classical period, whose exact years remain a matter of tradition rather than firm record.
