Famous quotes containing the word double:

    One key, one solution to the mysteries of the human condition, one solution to the old knots of fate, freedom, and foreknowledge, exists, the propounding, namely, of the double consciousness. A man must ride alternately on the horses of his private and public nature, as the equestrians in the circus throw themselves nimbly from horse to horse, or plant one foot on the back of one, and the other foot on the back of the other.
    Ralph Waldo Emerson (1803–1882)

    Was it the double of my dream
    The woman that by me lay
    Dreamed, or did we halve a dream
    Under the first cold gleam of day?
    William Butler Yeats (1865–1939)

    You spotted snakes with double tongue,
    Thorny hedgehogs, be not seen.
    Newts and blindworms, do no wrong,
    Come not near our Fairy Queen.
    William Shakespeare (1564–1616)
