Mental Existence; A Comparative Study of Ibn Sina and Fakhr Razi

Mental existence is one of the hot issues in philosophy. Agnosticists and Sophists have tried, unsuccessfully, to deny it, and it has added to its import as well as its epistemological direction. Such philosophers as Ibn Sina and Fakhr Razi are among avant-gardes to deal with this issue, and paved the way for more discussion in this regard. Surprisingly, Ibn Sina’s efforts have sometimes been neglected, and Fakhr Razi is thought to have rejected this idea. The authors want to show the inaccuracy of such claims, and to prove otherwise. They do this through interpreting different passages in the two philosophers’ works, some of which suffer from ambiguity, along with explaining the nature of mental existence and arguments for their existence. Moreover, a comparison between the two seems helpful in this regard.
