This paper is going to be a small study in the arena of comparative philosophy of the east and west. This study will show that ancient philosophies of India are still relevant in the modern world, and the modern philosophies in the western world is not a fruit of frustration, but both of them are two chief currents of thebrilliancy of human mind according to the development of human being and their need. Advaita Vedanta finds its extreme in nonduality, or (...) non-existence of brahman, which is the negation of all materialistic subjects\ topics \things in this world, or basically it denies the complete existence of the present world. On the other hand, Post Modernism finds its goal in decentralization of any object\theory in this world. Therefore, we can say that the both the systems have almost same conclusion regarding the non-existence or decentralization, but there is a radical difference in their dates. Advaita Vedanta and Post Modernism have also similarity in their methods to find their conclusions: “netineti” is a prime tool for Advaita Vedanta to prove the non-existence of brahman, and Post Modernism follows the “logic of Difference” to decentralize any existence in this world. This study will explore the differences and similarities of both of the systems, and will try to present a common conclusion, which should be acceptable for both of the systems. (shrink)
