Few men are willing to brave the disapproval of their fellows, the censure of their colleagues, the wrath of their society. Moral courage is a rarer commodity than bravery in battle or great intelligence. Yet it is the one essential, vital quality for those who seek to change a world which yields most painfully to change . . . I believe that in this generation those with the courage to enter the moral conflict will find themselves with companions in every corner of the world.
