Famous quotes containing the words free, engine and/or content:

    “Long live Free Quebec!
    (Vive le Québec Libre!”
    —Charles De Gaulle (1890–1970)

    “The will is never free—it is always attached to an object, a purpose. It is simply the engine in the car—it can’t steer.”
    —Joyce Cary (1888–1957)

    “Women are angels, wooing;
    Things won are done, joy’s soul lies in the doing.
    That she beloved knows naught that knows not this:
    Men prize the thing ungained more than it is.
    That she was never yet that ever knew
    Love got so sweet as when desire did sue.
    Therefore this maxim out of love I teach:
    Achievement is command; ungained, beseech.
    Then though my heart’s content firm love doth bear,
    Nothing of that shall from mine eyes appear.”
    —William Shakespeare (1564–1616)
