Synopsis Jainism nd Buddhism exercised, for several centuries, a poient influence on the system of philosophy and culture of Brahmanas. In the Deccan, the decline of Buddhism commenced in the 6th century AD, while in North India the Buddhists became almost extinct by 1200 AD. The Brahmanas who survived them, book back into their folds some of their Members who had embraced Buddhism and Jainism, but there arose the necessity of making strict rules for the maintenance of the integrity of their society and for the prevention of new admissions into it. The treatises on logic, which were composed by them, borrowed their forms from the works of medieval school , while for their subject matter they went back to the works of ancient schools. The works so composed in this period were technically called "Prakaranas" or manuals of logic. Bhasarvajfia, the celebrated author of Nyayasara, who flourished about 950 AD was one of the earlierst writers representing the Medieval school of Indian Logic. He was the first writer who attempted to reduce the sixteen categories to one. His well-known logical treastise "Nyayasara" or "the Essence of Logic" follows the method current in his time and treats only of pramana which is divided into three only to pramana which is divided into three kinds: perception (pratyaksa), inference (Anumana) and verbal testimony (Agame). This three-fold division of pramana furnished a contrast to Aksapada who recognized a fourth kind named comparison. This position has brought Bhasarvajfia close to the Samkhya and Jainas who admitted only three kinds of Pramanas as against the Buddhists who dealt with only two viz, perception and inference. A detailed study of the text bringing out its special characteristics and estimating its contribution to Nyaya Philosophy has not so far been done. The present work is an attempt in this direction.
