Abstract

It has generally been assumed that Anselm was the originator of the ontological argument. Notwithstanding the fact that it has received much criticism, Malcolm defends its so-called second version. In this paper we shall examine some features of ibn Sina’s notion of the Necessary Existent which show that prior to Anselm, ibn Sina formulated a version of this argument which corresponds in some senses to Malcolm’s version, and that a close examination of ibn Sina’s peculiar version enables us to criticize Malcolm’s version as it has not been done heretofore.
