Tarka-Sangraha is a treatise in Sanskrit giving a foundational exposition of the ancient Indian system of logic and reasoning. The work is authored by Annambhatta and the author himself has given a detailed commentary, called Tarka-Sangraha Deepika, for the text. Annambhatta composed the text as well as the commentary in the second half of 17th century CE. The text of Tarka-sangraha is a small book with about 15 pages only and it was composed to help boys and girls learn easily the basic principles of Nyaya. Of all the works of Annambhatta, only Tarka-Sangraha and its commentary attained wide acceptance. They have been used as basic text for beginners for several generations.
In Indian philosophical writings, the traditional structure of presenting a system consisted of three things: uddesa (listing of items to be discussed), laksana (defining each item in the list) and pariksa (critically examining whether the definitions apply properly to the items defined). The Tarka-Sangraha follows this model except for the third item of pariksa. The text presents the ontology, logic and epistemology of the Nyaya-Vaiseshika system.
Practically only very little is known about Annambhatta the author of Tarka-Sangraha. From the scanty references to other works and writers contained in his works, it has been estimated that Annambhatta must be a comparatively modern author and he must have flourished during the seventeenth century CE. His father's name was Advaitavidyacarya Tirumala. He was Tailanga Brahmin of North Arcot District of erstwhile state of Andhra Pradesh who had settled down in Benares. Tirumala was a Rigvedi Smarta Brahmana well versed in Vedanta philosophy. Annambhatta was a learned man in several areas of traditional scholarship, namely, Nyaya, Vyakarana, Vedanta and Purva-Mimamsa. Though not as well-known as Tarka-Sangraha, many of Annambhatta's works on other disciplines have survived. Besides, Tarka-Sangraha and its Commentary Dipika, the following works have been attributed to Annambhatta:
