Famous quotes containing the words heavy and/or oil:

    “The great end of life is not knowledge, but action. What men need is as much knowledge as they can assimilate and organize into a basis for action; give them more and it may become injurious. One knows people who are as heavy and stupid from undigested learning as other are from over-fulness of meat and drink.”
    —Thomas Henry Huxley (1825–95)

    “Is a park any better than a coal mine? What’s a mountain got that a slag pile hasn’t? What would you rather have in your garden—an almond tree or an oil well?”
    —Jean Giraudoux (1882–1944)
