Poetry is sane because it floats easily in an infinite sea; reason seeks to cross the infinite sea and so make it finite. The result is mental exhaustion. To accept everything is an exercise, to understand everything a strain.
To do Mohammed justice, his main attack was against the idolatries of Asia. Only he thought, just as the Arians did and just as the Unitarians do, that he could attack them better with a greater approximation to plain theism. What distinguishes his heresy from anything like an Arian or Albigensian heresy is that, as it sprang up on the borders of Christendom, it could spread outwards to a barbaric world.
Life is serious all the time, but living cannot be. You may have all the solemnity you wish in your neckties, but in anything important (such as sex, death, and religion), you must have mirth or you will have madness.
The Christian pities men because they are dying, and the Buddhist pities them because they are living. The Christian is sorry for what damages the life of a man; but the Buddhist is sorry for him because he is alive.
Tradition is only democracy extended through time; it may be defined as an extension of the franchise. Tradition means giving votes to the most obscure of all classes, our ancestors. It is the democracy of the dead. Tradition refuses to submit to the small and arrogant oligarchy of those who are merely walking about. All democrats object to men being disqualified by accident of birth; tradition objects to their being disqualified by accident of death. Democracy tells us not to neglect a good man's opinion, even if he is our father.
It is the beginning of all true criticism of our time to realize that it has really nothing to say, at the very moment when it has invented so tremendous a trumpet for saying it.
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.
