Men can construct a science with very few instruments, or with very plain instruments; but no one on earth could construct a science with unreliable instruments. A man might work out the whole of mathematics with a handful of pebbles, but not with a handful of clay which was always falling apart into new fragments, and falling together into new combinations. A man might measure heaven and earth with a reed, but not with a growing reed.
It is the friction of two spiritual things, of tradition and invention, or of substance and symbol, from which the mind takes fire. The creeds condemned as complex have something like the secret of sex; they can breed thoughts.
If Christianity should happen to be true - that is to say, if its God is the real God of the universe - then defending it may mean talking about anything and everything.
In the end it will not matter to us whether we wrote well or ill; whether we fought with flails or reeds. It will matter to us greatly on what side we fought.
There is not really any courage at all in attacking hoary or antiquated things, any more than in offering to fight one's grandmother. The really courageous man is he who defies tyrannies young as the morning and superstitions fresh as the first flowers. The only true free-thinker is he whose intellect is as much free from the future as from the past.
Folk-lore means that the soul is sane, but that the universe is wild and full of marvels. Realism means that the world is dull and full of routine, but that the soul is sick and screaming. The problem of the fairy tale is: what will a healthy man do with a fantastic world? The problems of the modern novel is: what will a madman do with a dull world? In the fairy tales the cosmos goes mad; but the hero does not go mad. In the modern novels the hero is mad before the book begins, and suffers from the harsh steadiness and cruel sanity of the cosmos.
