Celestial Object

Famous quotes containing the words celestial and/or object:

“Adam inquires concerning celestial motions, is doubtfully answered, and exhorted to search rather things more worthy of knowledge.”
—John Milton (1608–1614)

“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)
