Kripke Frames

Famous quotes containing the words kripke and/or frames:

    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)

    In frames as large as rooms that face all ways
    And block the ends of streets with giant loaves,
    Screen graves with custard, cover slums with praise
    Of motor-oil and cuts of salmon, shine
    Perpetually these sharply-pictured groves
    Of how life should be.
    Philip Larkin (1922–1986)
