Famous quotes containing the word nut:

    One of the last of the philosophers,—Connecticut gave him to the world,—he peddled first her wares, afterwards, as he declares, his brains. These he peddles still, prompting God and disgracing man, bearing for fruit his brain only, like the nut its kernel.
    Henry David Thoreau (1817–1862)
