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)

    “His education lay like a film of white oil on the black lake of his barbarian consciousness. For this reason, the things he said were hardly interesting at all. Only what he was.”
    —D.H. (David Herbert)
