Concept of Entity and a Philosophical Approach to Entity and City Nature

The research is derived from the master thesis of urban design, which is presented with the topic of promoting the physical entity of image and landscape of Islamshahr at Shahid Rajaee University. Existing views on the quiddity of city entity and its causes1are different and sometimes sporadic. Some researchers have identified entity as merely conceptual meaning2hidden in the history of the city, and other researchers look for entity in the integrity and continuity of physical features and the quality of the environment. The study, based on the fundamental difference between the concept of entity in western philosophy and Sadra’s philosophy, attempts to prove the entity of the city by considering the existential and primacy of the city entity, the relationship between essence and accidents, and the prologue and the epilogue of the statement of city entity. Two hypotheses, that is, the subjective and real existence of entity and introducing the minor premise and major premise for the existence of the entity (the prologue and the epilogue), determine the research strategy. The research method uses the qualitative -descriptive method using the theories in written documents and the logical and comparative reasoning of existing philosophical theories, including the primacy of existence, ontology, phenomenology, and substantial motion3 as a rational-philosophical inference. The results of research in the field of existential and inclusiveness of city entity can be used to explain the origin of the entity of city in the West and Islamic philosophy, the understanding of the relation between existence and nature to percept entity. Ultimately, the assumption that the entity of the city is dependent on the framework of city (like the soul that is manifested in the body) and that entity with the subjective and real concept is related to human relations, will be proved. A city without ideational backgrounds is like a body without soul. And the soul can’t be presented except in the form of a body and embodiment in the cognate appearance, which evidently is the nature or quality of the city.
