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)
“Whoever is not in the possession of leisure can hardly be said to possess independence. They talk of the dignity of work. Bosh. True work is the necessity of poor humanity’s earthly condition. The dignity is in leisure. Besides, 99 hundredths of all the work done in the world is either foolish and unnecessary, or harmful and wicked.”
—Herman Melville (1819–1891)
