Edith Keeler: Now, I don't pretend to tell you how
to find happiness and love, when every day is just
a struggle to survive. But I do insist that you do
survive, because the days and the years ahead are
worth living for. One day soon, man is going to be
able to harness incredible energies, maybe even the
