10. Modality / E. Possible worlds / 1. Possible Worlds / b. Impossible worlds

13749	Belief in impossible worlds may require dialetheism [Schaffer,J]
	Full Idea: One motivation for dialetheism is the view that there are impossible worlds.
	From: Jonathan Schaffer (On What Grounds What [2009], 2.3)

10. Modality / E. Possible worlds / 2. Nature of Possible Worlds / a. Nature of possible worlds

14189	'Modal realists' believe in many concrete worlds, 'actualists' in just this world, 'ersatzists' in abstract other worlds [Paul,LA]
	Full Idea: A 'modal realist' believes that there are many concrete worlds, while the 'actualist' believes in only one concrete world, the actual world. The 'ersatzist' is an actualist who takes nonactual possible worlds and their contents to be abstracta.
	From: L.A. Paul (In Defense of Essentialism [2006], Intro)
	A reaction: My view is something like that modal realism is wrong, and actualism is right, and possible worlds (if they really are that useful) are convenient abstract fictions, constructed (if we have any sense) out of the real possibilities in the actual world.
