Carvaka philosophy is one of the extreme nastika systems in Indian Philosophy. It does not accept the authorities of Vedas, the existence of transcendental realities like God,soul, and so on. The references of this school are found in the epics and in the early Buddhistic literature. It was mainly aroused as a protest against the excessive monkdon of the Brahaman priest. ‘Carvaka’ is the word that generally stands for ‘materialist’ .But the original meaning of the word is shrounded in mystery. However, according to one view carvaka was originally the name of a sage who propounded materialism. But for another, the word ‘carvaka’ is not a proper name; it is a common name given to a materialist and it signifies a person who believes in ‘eating’, ‘drinking’and be merry,or a person who eats up his own words, or who eats up all moral and ethical consideration, or a peson having a sweet tongue.Infact, whatever the word carvaka signifies , it mainly utters that matter is the only ultimate reality. That is why, Carvaka philosophy is also termed as ‘Materialism’.This carvaka philosophy has obtained more popularity among ordinary people. Whatever the theories or statements are given by this school is accepted by all common people. In this article I just try to focus the points why this school is embranced to all ordinary people .Along with this I also try to bring some criticisms against it collected from different angles.
