Famous quotes containing the words version and/or history:

    If the only new thing we have to offer is an improved version of the past, then today can only be inferior to yesterday. Hypnotised by images of the past, we risk losing all capacity for creative change.
    Robert Hewison (b. 1943)

    I believe that history might be, and ought to be, taught in a new fashion so as to make the meaning of it as a process of evolution intelligible to the young.
    Thomas Henry Huxley (1825–95)
