Doctor Chesterton's Orthodoxy Pills.

Poetry is sane because it floats easily in an infinite sea; reason seeks to cross the infinite sea and make it finite. (...) To accept everything is an exercise, to understand everything a strain. The poet only desires exaltation and expansion, a world to strecht himself in. The poet only asks to get his head into the heavens. It is the logician who seeks to get the heavens into his head. And it is his head that splits.
