In the history of religious and philosophical thought of India, Charvaka philosophy is a unique school of thought that by having theoretical tenets of materialism, provides a purely materialistic interpretation of existence. This school, through the negation of realm beyond sensory perception, asserts to the pure originality of the material and supposes that the only the material reality has validity and the sole authentic perception is the sensory perception. Expressing of atomistic cosmology, apparently, Epicurean philosophy in Greece is the most (...) similar school of thought to Charvakh. The findings of this article which is obtained by method of comparison and analyze, shows that in both schools of thought, reality is based on the originality of the material, two kinds of causes are rejected, human’s existence is explained only based on his material dimension, as well as any existence after death is denied. However, these two of philosophy offer different interpretations about the component of existence and nature and kinds of them as well as about tangible or intangible of them. (shrink)
