Conceptual necessity is a property of the certainty with which a state of affairs, as presented by a certain description, occurs: it occurs by conceptual necessity if and only if it occurs just by virtue of the meaning of the description. If someone is a bachelor, for instance, then he is bound to be unmarried by conceptual necessity, because the meaning of the word "bachelor" determines that he is.
Alternatively, there is metaphysical necessity, which is a certainty determined, not by the meaning of a description, but instead by facts in the world described.
Famous quotes containing the words conceptual and/or necessity:
“I thought it was a wonderfully conceptual act actually, to fire a replica pistol at a figurehead—the guy could have been working for Andy Warhol!”
—J.G. (James Graham)
“The secret of the illusoriness is in the necessity of a succession of moods or objects. Gladly we would anchor, but the anchorage is quicksand.”
—Ralph Waldo Emerson (1803–1882)
