Famous quotes containing the word double:

    I grew up confidently expecting to have a profession and earn my own living, and also confidently expecting to be married and have children. It was fifty-fifty with me. I was just as passionately determined to have children as I was to have a career. And my mother was the triumphant answer to all doubts as to the success of this double role. From my earliest memory she had more than half supported the family and yet she was supremely a mother.
    Crystal Eastman (1881–1928)

    [The] elderly and timid single gentleman in Paris ... never drove down the Champs Elysees without expecting an accident, and commonly witnessing one; or found himself in the neighborhood of an official without calculating the chances of a bomb. So long as the rates of progress held good, these bombs would double in force and number every ten years.
    Henry Brooks Adams (1838–1918)

    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)
