Most people, when asked what spirtual quality is needed to rebuild civilization, will reply 'Love'. Men must love one another, they say, nations must do likewise. Respectfully but firmly, I disagree. Love is a great force in private life; it is indeed the of all things; but love in public affairs and again; by the christian civilization of the Middle Ages, and also by the French Revolution, a secular movement which reaserted the brotherhood of man. And it has always failed. The idea that nations should love one another, or that business concerns or marketing boards should love one another, or that a man in Portugal should love a man in Peru of whom he has rever heard is absurd, unreal dangerous. It leads us into perilous and vague sentimentalism. Love is what is needed' we chant and then sit back and the world goes on as before. The fact is we can only love what we know personally, And we cannot know much. In public affairs, in the rebuilding of our civilization, something much less dramatic and emotional is needed namely tolerance. Tolerance is a very dull virtue. It is negative.
