The Dialectic of Existence and Presence in the Field of Molla Sadra's Philosophy

The existence and presence are two principles in the field of ontology and epistemology is the wisdom of Sadra. Mulla Sadra in the ontology dimension based on the originality of existence, considers the truth of existence as the subject of philosophy. Although he is called the existing as the subject of philosophy in some positions such as Avicenna, but he finally separates his path and chooses the truth of existence as the subject of philosophy. He considered two criterions of originality and generality in proving the subject of philosophy such as the previous philosophers. The originality and the generality of existence in Sadra's philosophy fits to the truth that is same as exteriority and the originality of the effect, but the originality and the generality of existence in Avicenna's philosophy points to a concept that contents all the creatures of the world by its extent with uncertainty. The theme of truth in the wisdom of Sadra and its main role in philosophical issues requires the presence as the main part in the field of epistemology of this wisdom. Because knowledge of existence is not possible except through presence and Visual knowledge and what is obtained from the truth in the mind and through adventitious knowledge is a weak view of it. The existence presents truth and presence and this coherence of existence and truth and presence is the main part of ontology and epistemology of Mulla Sadra's philosophy.
