Famous quotes containing the word exploration:

    The future author is one who discovers that language, the exploration and manipulation of the resources of language, will serve him in winning through to his way.
    Thornton Wilder (1897–1975)

    Typography tended to alter language from a means of perception and exploration to a portable commodity.
    Marshall McLuhan (1911–1980)

    For women who do not love us, as for the “disappeared”, knowing that we no longer have any hope does not prevent us form continuing to wait. We live on our guard, on watch; women whose son has gone asea on a dangerous exploration imagine at any minute, although it has long been certain that he has perished, that he will enter, miraculously saved, and healthy.
    Marcel Proust (1871–1922)
