Abstract
Mulla Sadra and Leibniz are two philosophers of the East and the West, and belong to two different worlds. Though they were unaware of ideas of each other, they share certain points that are comparable. Monads constitute the basis of Leibniz's thought and he refer to their features in his various works. Mulla Sadra's philosophy also is based on being and he tried to deal with its reality in his philosophy. Though Leibniz's monads are many and Mulla Sadras being is one, they use certain terms for monads and being which are very close to each other and are comparable from different points of view. Leibniz monads while being many are one as well. Similarly Mulla Sadra's philosophy too enjoys multiplicity in unity. Leibniz's monads enjoy perception and Mulla Sadra's being too coexist withknowledge. In this paper apart from comparing Leibniz's monads and Mulla Sadra's concept of being, their philosophies also have been compared and their common and different points have been unraveled.
