"Sarvadarśanasaṅgraha" is one of the few available sources of information about "lokayata", the materialist system of philosophy in ancient India. In the very first chapter, "The Cārvāka System", he critiques the arguments of "lokayatika"s. While doing so he quotes extensively from Cārvāka works. It is possible that some of these arguments put forward as the "lokayata" point of view may be a mere caricature of "lokayata" philosophy. Yet in the absence of any original work of "lokayatika"s, it is one of the very few sources of information available today on materialist philosophy in ancient India.
