Abstract

After briefly discussing the various versions of the principle of sufficient reason (hereafter PSR), I argue that Clarke’s classic version of the cosmological arguments for the existence of God is rooted in the PSR, while Sadra’s so-called Siddigin argument is not based on any weak or strong version of PSR. My paper is thus divided into three parts: (1) the PSR and its significance concerning the cosmological arguments for the existence of God, (2) Clarke’s version of cosmological argument and its dependence on the PSR, (3) Sadra’s Siddigin argument for the existence of a necessary being -- as a proper correspondent to what constitutes the nature of cosmological arguments -- and its independence from PSR
