REALISM ABOUT POSSIBLE WORLDS

Abstract

There are many things which do not exist. in particular, there are more possible worlds than the actual one, thought every other one is something that is actually possible, and the possibility of it is actual (existent). "actual" and "exist" are not really indexicals since "world" (best understood as a comprehensive ensemble of existence) isn't. thus, ordinary language, david k lewis' sole support for his "realism" regarding possible worlds, does not really support it.
