Famous quotes containing the word history:

    The history of medicine is the history of the unusual.
    Robert M. Fresco, and Jack Arnold. Prof. Gerald Deemer (Leo G. Carroll)

    Gilbert Keith Chesterton (1874–1936)

    Anything in history or nature that can be described as changing steadily can be seen as heading toward catastrophe.
    Susan Sontag (b. 1933)
