Famous quotes containing the words sandstone and/or beacon:

    But the lightning which explodes and fashions planets, maker of planets and suns, is in him. On one side elemental order, sandstone and granite, rock-ledges, peat-bog, forest, sea and shore; and on the other part, thought, the spirit which composes and decomposes nature,—here they are, side by side, god and devil, mind and matter, king and conspirator, belt and spasm, riding peacefully together in the eye and brain of every man.
    Ralph Waldo Emerson (1803–1882)

    It illumineth the face, which as a beacon gives warning to all the rest of this little kingdom, man, to arm ... this valor comes of sherris.
    William Shakespeare (1564–1616)
