Famous quotes containing the words rigid and/or vehicle:
“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)
“How strange a vehicle it is, coming down unchanged from times of old romance, and so characteristically black, the way no other thing is black except a coffin—a vehicle evoking lawless adventures in the plashing stillness of night, and still more strongly evoking death itself, the bier, the dark obsequies, the last silent journey!”
—Thomas Mann (1875–1955)
