Rigid

Famous quotes containing the word rigid:

    Pain hardens, and great pain hardens greatly, whatever the comforters say, and suffering does not ennoble, though it may occasionally lend a certain rigid dignity of manner to the suffering frame.
    —A.S. (Antonia Susan)

    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)
