Sedimentary Rock Composed

Famous quotes containing the words rock and/or composed:

    Men are afraid to rock the boat in which they hope to drift safely through life’s currents, when, actually, the boat is stuck on a sandbar. They would be better off to rock the boat and try to shake it loose, or, better still, jump in the water and swim for the shore.
    Thomas Szasz (b. 1920)

    In a universe that is all gradations of matter, from gross to fine to finer, so that we end up with everything we are composed of in a lattice, a grid, a mesh, a mist, where particles or movements so small we cannot observe them are held in a strict and accurate web, that is nevertheless nonexistent to the eyes we use for ordinary living—in this system of fine and finer, where then is the substance of a thought?
    Doris Lessing (b. 1919)
