وحدت جهان

The Unity of World

The theory of the unity of the world was considered in different types in the history of humanʹs thought. The supporters of this theory have tried to prove it in many ways. In contrast to this theory, there is the concept of possible Worlds that accept multiplicity of the world. In this paper we try to have a critical discussion on each of these two theories. Then we evaluate the reasons and justifications of each of them.
