Famous quotes containing the word flight:

    One man’s observation is another man’s closed book or flight of fancy.
    Willard Van Orman Quine (b. 1908)

    AIDS was ... an illness in stages, a very long flight of steps that led assuredly to death, but whose every step represented a unique apprenticeship. It was a disease that gave death time to live and its victims time to die, time to discover time, and in the end to discover life.
    Hervé Guibert (1955–1991)
