The Considerations of the Essence; Avicennian Invention and Aghaali Zonouzi's Innovation

In Islamic philosophy, the essence has many properties in which the considerations of essence are one of them. After this issue had been brought up, three key concepts had been raised in the works of Islamic philosophers around the essence that the connection of these concepts created a great deal of difference and conflicts. These three concepts are the concept of 'natural universal', the concept of 'Quiddity qua quiddity' and the concept of 'Nonconditioned quiddity'. There are two popular views among philosophers regarding the relevance of these concepts. The first view considers 'natural universal' and 'Quiddity qua quiddity' to be in accordance with the non-conditioned as a source of division. The second view, contrary to the first view, holds that both of these concepts are consistent with non-conditioned. Ibn Sina is the first one who invented this problem and falls into the second group, and Agha Ali represents a third view that explicitly considers the views of other philosophers to be unfinished and offered a new idea which is the last step in the philosophical improvement of this idea. From Agha Ali's point of view on the considerations of the essence, we can have a better analysis of Essential primary and technical common predications, consideration of the essence of God and some other philosophical issues.
