Geological Period

Famous quotes containing the words geological and/or period:

    The crystal sphere of thought is as concentrical as the geological structure of the globe. As our soils and rocks lie in strata, concentric strata, so do all men’s thinkings run laterally, never vertically.
    Ralph Waldo Emerson (1803–1882)

    If there is any period one would desire to be born in, is it not the age of Revolution; when the old and the new stand side by side, and admit of being compared; when the energies of all men are searched by fear and by hope; when the historic glories of the old can be compensated by the rich possibilities of the new era?
    Ralph Waldo Emerson (1803–1882)
