Famous quotes containing the words features and/or version:

    “Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
    —Henry David Thoreau (1817–1862)

    “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)
