As for others and the world around him he never ceased in his heroic and earnest endeavor to love them, to be just to them, to do them no harm, for the love of his neighbor was as deeply in him as the hatred of himself, and so his whole life was an example that love of one's neighbor is not possible without love of one's self, and that self-hate is really the same thing as sheer egoism and in the long run breeds the same cruel isolation and despair.
