The fundamentality of existence has given rise to a key philosophical debate since Molla Sadra, forming the backbone of his transcendental philosophy. In this paper, the logical necessity and unity of existence in his theory of the fundamentality of existence are discussed. The question is whether the theory entails necessity as well as unity, without acknowledging any diversity of existence. For Molla Sadra, whereas the fundamentality of existence entails the necessity of existence, in itself it does not deny the possibility of diversity, however, it is claimed to be asuperficial diversity.
