Vacuous Truths About Pegasus

From Stanford, notes to "nonexistent objects", online:

"Priest claims that non-actual worlds themselves are nonexistent objects. This view, together with what has been said above, seems to entail (although Priest does not say so explicitly) that nonexistent worlds are constituted (partly) by existent objects."

"For Pegasus, for instance, exists in those worlds which are such as described in Greek mythology."

"Seemingly, it will not do to say that Pegasus does not “really” exist in those worlds (since those worlds are nonexistent), because Pegasus is said literally to have existence-entailing properties in those worlds, and if existence in a nonexistent world were not “real” existence, it seems that, consequently, objects existing in a nonexistent world could not literally have existence-entailing properties."
