The idea of hell was born of ignorance, brutality, fear, cowardice, and revenge. This idea testifies that our remote ancestors were the lowest beasts. Only from dens, lairs, and caves, only from mouths filled with cruel fangs, only from hearts of fear and hatred, only from the conscience of hunger and lust, only from the lowest and most debased could come this most cruel, heartless and bestial of all dogmas. Our barbarian ancestors knew but little of nature. They were too astonished to investigate. They could not divest themselves of the idea that everything happened with reference to them; that they caused storms and earthquakes; that they brought the tempest and the whirlwind; that on account of something they had done, or omitted to do, the lightning of vengeance leaped from the darkened sky. They made up their minds that at least two vast and powerful beings presided over this world; that one was good and the other bad; that both of these beings wished to get control of the souls of men; that they were relentless enemies, eternal foes; that both welcomed recruits and hated deserters; that both demanded praise and worship; that one offered rewards in this world, and the other in the next. The Devil has paid cash--God buys on credit. Man saw cruelty and mercy in nature, because he imagined that phenomena were produced to punish or to reward him. When his poor hut was torn and broken by the wind, he thought it a punishment. When some town or city was swept away by flood or sea, he imagined that the crimes of the inhabitants had been avenged. When the land was filled with plenty, when the seasons were kind, he thought that he had pleased the tyrant of the skies.
