Famous quotes containing the words busy, beaver and/or proof:

    But I am not tragically colored. There is no great sorrow dammed up in my soul, nor lurking behind my eyes. I do not mind at all.

    The mission of men there seems to be, like so many busy demons, to drive the forest all out of the country, from every solitary beaver swamp and mountain-side, as soon as possible.

    From whichever angle one looks at it, the application of racial theories remains a striking proof of the lowered demands of public opinion upon the purity of critical judgment.
    Johan Huizinga (1872–1945)
