“...given sufficient ignorance, one can doubt evolution....”

“If the history-deniers who doubt the fact of evolution are ignorant of biology, those who think the world began less than ten thousand years ago are worst than ignorant, they are the deluded to the point of perversity.”

“To put it bluntly but fairly, anyone today who doubts that the variety of life on this planet was produced by a process of evolution is simply ignorant—inexcusably ignorant, in a world where three out of four people have learned to read and write.”

“Life had already given him sufficient reasons for knowing that no defeat was the final one.”

“Given enough time, even evolution evolves.”

“I have learned two lessons in my life: first, there are no sufficient literary, psychological, or historical answers to human tragedy, only moral ones. Second, just as despair can come to one another only from other human beings, hope, too, can be given to one only by other human beings.”
