This scholarly work of Dr S.M.S. Chari's deals with the critical review of seventeen philosophical systems as presented in an important philosophical treatise of the thirteenth century titled Paramata-bhanga contributed by Vedanta Desika, an illustrious successor to Ramanuja, who is the chief exponent of Visistadvaita Vedanta. The main objective of Paramata-bhanga is to establish that Visistadvaita is a sound system of philosophy as compared to the several other Non-Vedic as well as Vedic schools and also Vedanta schools developed by Samkara, Yadavaprakasa, Bhaskara, and other exponents of the post-Ramanuja period. The original text written in Manipravala (a mixture of Tamil and Sanskrit) language contains, besides a brief account of the fundamental doctrines of Visistadvaita. The schools covered are Carvaka, Buddhism, Jainism, Sankhya, Yoga, Vaisesika, Nyaya, Purvamimamsa, Pasupata, Sabdabrahma-vivartavada, and Advaita Vedanta. Among the extant philosophical classics, Paramata-bhanga is a unique work. Realizing the importance of the Paramata-bhanga for the comparative study of Indian philosophy, late Dr Chari tried to give a lucid exposition of this treatise in English. This volume, which is the first of its kind, would be invaluable for students of Indian philosophy in general and Visistadvaita in particular
