Require

Famous quotes containing the word require:

“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)

“We should be slow to mend, my friends, as slow to require mending.”
—Henry David Thoreau (1817–1862)

“The companion of an evening, and the companion for life, require very different qualifications.”
—Samuel Richardson (1689–1761)
