Famous quotes containing the words space and/or exploration:
“If we remembered everything, we should on most occasions be as ill off as if we remembered nothing. It would take us as long to recall a space of time as it took the original time to elapse, and we should never get ahead with our thinking. All recollected times undergo, accordingly, what M. Ribot calls foreshortening; and this foreshortening is due to the omission of an enormous number of facts which filled them.”
—William James (1842–1910)
“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)
