Famous quotes containing the word john:

    No such sermons have come to us here out of England, in late years, as those of this preacher,—sermons to kings, and sermons to peasants, and sermons to all intermediate classes. It is in vain that John Bull, or any of his cousins, turns a deaf ear, and pretends not to hear them: nature will not soon be weary of repeating them. There are words less obviously true, more for the ages to hear, perhaps, but none so impossible for this age not to hear.
    Henry David Thoreau (1817–1862)
