Requirements of Ghias al-Din Mansour Dashtaki's enunciation with Mulla Sadra's principality of Existence

One of the most basic philosophical topics is the discussion of The Principality of Existence or Quiddity, which plays a decisive role in intellectual-philosophical positions. Mulla Sadra proved the "The Principality of Existence" as the basis of transcendental Philosophy based on solid arguments, and by studing the scoulars before him, he considered the prepatetics to believe in The Principality of Existence and the Ishraqi in The Principality of Quiddity. Although the question of The Principality of Existence or Quiddity has not been raised in the sense of Sadraian by early scoulars, but by examining their works and expressions, one of the parties to the issue in question can be attributed to them. This research tries to show that despite Ghias al-Din's statements and positions on "The Principality of Existence", because at that time the issue of the Principality of Existence had not yet been properly revised and as he did not pay attention to the consequences of the Principality of Existence, his opinions in some topics such as mental existence, intensification in quality and perfection of the soul with the "The Principality of Quiddity" are incompatible.
