Famous quotes containing the word rigid:
“It is the custom of the Roman Church which I unworthily serve with the help of God, to tolerate some things, to turn a blind eye to some, following the spirit of discretion rather than the rigid letter of the law.”
—Pope Gregory VII (c. 1020–1085)
“The essence of statesmanship is not a rigid adherence to the past, but a prudent and probing concern for the future.”
—Hubert H. Humphrey (1911–1978)
“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)
