Famous quotes containing the words crystal, cave and/or property:
“Wise men read very sharply all your private history in your look and gait and behavior. The whole economy of nature is bent on expression. The tell-tale body is all tongues. Men are like Geneva watches with crystal faces which expose the whole movement.”
—Ralph Waldo Emerson (1803–1882)
“The Cave of Jeremiah is in this part. In its lamentable recesses he composed his lamentable Lamentations.”
—Herman Melville (1819–1891)
“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)
