Cosmopolitan of light as the Utopia of philosophy of cosmopolitan

According to the place of light in the philosophy of illumination, this question arises that: Why Suhrawardi has used light instead of the divine being on one hand, and the longitude and latitude as homeland on the other hand?This article tries to prove the illuminate cosmopolitanism from Suhrawardi’s viewpoint. Suhrawardi’s cosmopolitan is investigated via the ontology of light and as a result, the meaning of homeland is explored from philosophy of illumination perspective. Since he has chosen light instead of being in ontological issues on one hand, and used the words associated with homeland including west and east on the other hand; his ontology is related to homeland and as a consequence, to cosmopolitanism. Accordingly, in his opinion, not only homeland is identical to existence but also it as the existence and the realm of homeland is expanded to all over the existence. In Suhrawardi’s cosmopolitan, since the humans belong to an ultimate reality, there is no difference among them and they are dignified in the same level. Hence, accidental differences including color, language, homeland and etc. do not offer specific right to a specific group and no group is superior to other.
