" Every person’s life is of importance to himself, of course: … But in the universe of infinite space and time, it is insignificant. … Perhaps Carl Becker, the historian, and one of the most civilized men I ever knew, grasped best our piddling place in the infinite.

Man [he wrote] is but a foundling in the cosmos, abandoned by the forces that created him. Unparented, unassisted and undirected by omniscient or benevolent authority, he must fend for himself, and with the aid of his own limited intelligence find his way about in an indifferent universe.

And in a rather savage world! The longer I lived and the more I observed, the clearer it became to me that man had progressed very little beyond his earlier savage state. After twenty million years or so of human life on this Earth, the lot of most men and women is, as Hobbes said, “nasty, brutish, and short.” Civilization is a thin veneer. It is so easily and continually eroded or cracked, leaving human beings exposed for what they are: savages.
What good three thousand years of so-called civilization, of religion, philosophy, and education, when … men go on torturing, killing and repressing their fellowmen? "
