Love is a great force in private life; it is indeed the greatest of all things: but love in public affairs simply does not work. It has been tried again and again: by the Christian civilisations of the Middle Ages, and also by the French Revolution, a secular movement which reasserted 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, say, should love a man in Peru of whom he has never heard—it is absurd, it is unreal, worse, it is 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 civilisation, something much less dramatic and emotional is needed, namely, tolerance.
