An Ontological and Epistemological Approach for God's Existence in Descarte's and Seddiqin Argument

Truly saying, the question of God`s existence is the same question of the origin and end of existence with a distinct place in philosophy. The claim may be seen in philosophers` extended attempts in their philosophical system on the basis of God`s existence. Explaining Descartes and Molla Sadr`s studies on God, one may find their differences and similarities. Explaining the place of theosophy in Descartes` philosophy, this paper studies the philosophers` arguments for the existence of God comparatively. Descartes` studies on the problem is clearly more epistemological than ontological and this way of study can also be recognized in Sadra`s studies. Such being the case, Descartes` epistemological studies and the importance given to the proofs for God`s existence have been proposed at first and, then, his ontological argument has been studied with a comparison with Sadra`s seddiqin.
