An entertaining bit from Vril, the power of the coming race, a book published in 1871 that describes a superior race called the An that live beneath the surface of the earth:

"They say that in ancient times there was a great number of books written upon speculations as to the nature of the Deity, and upon the forms of belief or worship supposed to be most agreeable to Him. But these were found to lead to such heated and angry disputations as not only to shake the peace of the community and divide families before the most united, but in the course of discussing the attributes of the Deity, the existence of the Deity Himself became argued away, or, what was worse, became invested with the passions and infirmities of the human disputants. "For," said my host, "since a finite being like an An cannot possibly define the Infinite, so, when he endeavours to realise an idea of the Divinity, he only reduces the Divinity into an An like himself." During the later ages, therefore, all theological speculations, though not forbidden, have been so discouraged as to have fallen utterly into disuse."
