Here's a quote from the late GK Chesterton:

Poetry is sane

Poetry is sane because it floats easily in an infinite sea; reason seeks to cross the infinite seam and so make it finite. The result is mental exhaustion, like the physical exhaustion of Mr. Holbein. To accept everything is an exercise, to understand everything a strain. The poet only desires exaltation and expansion, a world to stretch himself in. The poet only asks to get his head into the heavens. It is the logician who seeks to get heaven into his head. And it is his head that splits.
