Human beings are all capable of suffering.
Human beings are capable of fear, of insecurity. They re also capable of love. They re capable of being hurt. From this fact, which is objective I mean, no one would deny that, no one would dream of it from this arise certain rules, which human beings are perfectly capable of discerning, which virtually everyone in this room has discerned, by himself, with the guidance of his parents and the guidance of his culture, not with the guidance of any God. The Greeks, whom I admire, from whose ethics I drew my own life s ideals, had no priesthood.
