Famous quotes containing the words ancestor and/or common:

    I cannot yet begin to understand
    Why we are proud that an ancestor knew
    The crazy Poe, who was not of our kind

    The difference between human vision and the image perceived by the faceted eye of an insect may be compared with the difference between a half-tone block made with the very finest screen and the corresponding picture as represented by the very coarse screening used in common newspaper pictorial reproduction. The same comparison holds good between the way Gogol saw things and the way average readers and average writers see things.
    Vladimir Nabokov (1899–1977)
