Famous quotes containing the words double and/or action:

    “The worst feature of this double consciousness is, that the two lives, of the understanding and of the soul, which we lead, really show very little relation to each other; never meet and measure each other: one prevails now, all buzz and din; and the other prevails then, all infinitude and paradise; and, with the progress of life, the two discover no greater disposition to reconcile themselves.”
    —Ralph Waldo Emerson (1803–1882)

    “You mustn’t look in my novel for the old stable ego of the character. There is another ego, according to whose action the individual is unrecognisable.”
    —D.H. (David Herbert)
