Sedimentary Rock Defined

Famous quotes containing the words rock and/or defined:

    Safe upon the solid rock the ugly houses stand:

    Long before Einstein told us that matter is energy, Machiavelli and Hobbes and other modern political philosophers defined man as a lump of matter whose most politically relevant attribute is a form of energy called “self-interestedness.” This was not a portrait of man “warts and all.” It was all wart.
    George F. Will (b. 1941)
