These are the things which might conceivably and truly make men forgive their enemies. We can only turn hate to love by understanding what are the things that men have loved; nor is it necessary to ask men to hate their loves in order to love one another. Just as two grocers are most likely to be reconciled when they remember for a moment that they are two fathers, so two nationals are most likely to be reconciled when they remember (if only for a moment) that they are two patriots.
It was the people who did not care who filled the world with fire and oppression. It was the hands of the indifferent that lit the faggots; it was the hands of the indifferent that turned the rack.
It is one thing to describe an interview with a gorgon or a griffin, a creature who does not exist. It is another thing to discover that the rhinoceros does exist and then take pleasure in the fact that he looks as if he didn't.
Science is the study of the admitted laws of existence, which cannot prove a universal negative about whether those laws could ever be suspended by something admittedly above them. It is as if we were to say that a lawyer was so deeply learned in the American Constitution that he knew there could never be a revolution in America.
But a somewhat more liberal and sympathetic examination of mankind will convince us that the cross is even older than the gibbet, that voluntary suffering was before and independent of compulsory; and in short that in most important matters a man has always been free to ruin himself if he chose.
The perils, rewards, punishments, and fulfillments of an adventure must be real, or the adventure is only a shifting and heartless nightmare. If I bet I must be made to pay, or there is no poetry in betting. If I challenge I must be made to fight, or there is no poetry in challenging. If I vow to be faithful I must be cursed when I am unfaithful, or there is no fun vowing.
Islam was something like a Christian heresy. The early heresies had been full of mad reversals and evasions of the Incarnation, rescuing their Jesus from the reality of his body even at the expense of the sincerity of his soul.
Religious and philosophical beliefs are, indeed, as dangerous as fire, and nothing can take from them that beauty of danger. But there is only one way of really guarding ourselves against the excessive danger of them, and that is to be steeped in philosophy and soaked in religion.
