The Nature of Essence

"Essence" and "existence" are among the fundamental and key concepts in the realm of philosophy, and one who has little familiarity with philosophical texts knows these two concepts. No doubt, explaining these concepts which are among the most basic philosophical concepts helps explain many philosophical questions the knowledge of which is based on this explanation. Using a library and documentary method, the present paper takes a probing look at some main issues related to the nature of essence. Explaining these issues will much help explain the issue of existence and its fundamentality, which has long been discussed and debated among philosophers. The most important findings of this paper are: realizing the essential and primary predication and common technical predication, recognizing the difference between negative attribute and negative real, realizing the aspects of essence to explain and reanalyze the famous forms of negation of two contradictories at the level of entity of essence.
