Famous quotes containing the words spectre and/or called:
“But there is nothing which delights and terrifies our English Theatre so much as a Ghost, especially when he appears in a bloody Shirt. A Spectre has very often saved a Play, though he has done nothing but stalked across the Stage, or rose through a Cleft of it, and sunk again without speaking one Word.”
—Joseph Addison (1672–1719)
“Let’s call something a rigid designator if in every possible world it designates the same object, a non-rigid or accidental designator if that is not the case. Of course we don’t require that the objects exist in all possible worlds.... When we think of a property as essential to an object we usually mean that it is true of that object in any case where it would have existed. A rigid designator of a necessary existent can be called strongly rigid.”
—Saul Kripke (b. 1940)
