Lunacy

Have I mentioned I love G.K. Chesterton?  He is so logically illogical.

"But the transcendentalism by which all men live has primarily much the position of the sun in the sky.  We are conscious of it as of a kind of splendid confusion; it is something both shining and shapeless, at once a blaze and a blur.  But the circle of the moon is as clear and unmistakable, as recurrent and inevitable, as the circle of Euclid on the blackboard.  For the moon is utterly reasonable; and the moon is the mother of lunatics and has given to them all her name." 

~G.K. Chesterton, Orthodoxy
