Vadanyaya is an important work by Dharmakirti on the theory of debate. The work is devoted to the rules of victory and defeat in debate. Dharmakirti has used the Nyaya Account of debate, not only as a purvapaksa, a position to be refuted, but also, at least partly, as a raw material for reconstruction. His Criticism of Nyaya is not purely destructive but it has a constructive aspect also. He gives his own classification of nigrahasthanas along with their definitions, in the first half of his work. In the Second half he devotes his work to the criticism of Nyaya classification of nigrahasthanas.
The present book contains critical text in Sanskrit, a detailed introduction, an English translation alongwith notes and a Glossary. The book is published in the Bubliotheca Indo-Buddhica Series.
