The philosophies in India evolved in the process of mutual rebuttal and confirmation. The Cārvāka philosophy is very unique and well-marked among Indian philosophies as it is the only philosophy in India which corroborates materialism. The twenty-first century is the century of materialism. This philosophy known as Lokāyata as well as Ānvīkṣikī is a logical system. In order to qualify to be a logical system it is necessary that this philosophy refutes the concepts of other philosophies and establishes its own concepts both on logical grounds. The philosophies such as Nyāya, Vaiśeṣika, Sāṁkhya, Jaina and Bauddha do the same; they refute the position of other philosophies on logical grounds and establish their own philosophy on the logical basis. But we observe this deficiency in the Cārvāka philosophy as this philosophy is not developed in tune with the development of other philosophies for whatsoever reasons. Everywhere this philosophy appears only as a pūrvapakṣa not siddhānta pakṣa. In this book there are redressals of the criticism of Cārvāka philosophy by the celebrated philosophers like Dharmakīrti, Śāntarakṣita, Kamalaśīla, Udayanācārya and Viśvanātha Nyāyapañcānana as well as their rebuttal from the Cārvāka point of view. This book is a reaffirmation of the Cārvāka philosophy on the basis of Cārvāka concepts and logical grounds. This is an invitation to the philosophers for a dialogue.
