David Kellogg Lewis, « Anselm and actuality », Philosophie, ID : 10670/1.fd63c0...
In “Anselm and Actuality” (1970), David Kellogg Lewis (1941–2001) offers a critical analysis of the ontological argument developed by Anselm of Canterbury in order to illustrate the content and scope of his central thesis, modal realism. Rejecting the ordinary view that mixes up real existence with actuality, Lewis shows that actual existence is in fact an indexical notion. Like “here,” “now,” or “this,” it only acquires meaning and significance by virtue of its context of enunciation. Disassociated from real existence, actuality, according to Lewis, only designates a narrow region of the vast realm of possibilities: the one we happen to inhabit.
