"Anyone whose attention and love are really directed towards the reality outside the world recognizes at the same time that he is bound, both in public and private life, by the single and permanent obligation to remedy, according to his responsibilities and to the extent of his power, all the privations of soul and body which are liable to destroy or damage the earthly life of any human being whatsoever. … The thought of this obligation is present to all men, but in very different forms and in very varying degrees of clarity. Some men are more and some are less inclined to accept — or to refuse — it as their rule of conduct."
