This is a reprint of the English Translation of the Nyaya Sutras of Gautama by Mm. Dr. Ganganatha Jha, the versatile Sanskrit scholar who will ever be remembered for his dedicated and selfless pioneer work and immense contribution in the field. The work was first published serially in the Indian Thought (Vols. IV-XI), a quarterly journal devoted to Sanskrit learning, over a period of eight years from 1912 to 1919. Dr. Jha's translation covers a large field and includes, besides the original Sutras of Gautama, the Bhasya of Vatsyayana and the Vartika of Uddyotakara in full as well as relevant notes from Vacaspati Misra's Nyayavartika-tatparyatika, Udayana's Tatparyaparisuddhi and Raghutama's Bhasyacandra. The work naturally became enormous in bulk and it is not surprising that it took for its completion so many years and so much energy of the author and as many as 1800 pages in print. This reprint of the great work is issued in response to the increasing demand of the scholars.
