[154] For their doctrine is this: That bodies are corruptible, and that the matter they are made of is not permanent; but that the souls are immortal, and continue for ever; and that they come out of the most subtile air, and are united to their bodies as to prisons, into which they are drawn by a certain natural enticement; but that when they are set free from the bonds of the flesh, they then, as released from a long bondage, rejoice and mount upward. And this is like the opinions of the Greeks, that good souls have their habitations beyond the ocean, in a region that is neither oppressed with storms of rain or snow, or with intense heat, but that this place is such as is refreshed by the gentle breathing of a west wind, that is perpetually blowing from the ocean; while they allot to bad souls a dark and tempestuous den, full of never-ceasing punishments. And indeed the Greeks seem to me to have followed the same notion, when they allot the islands of the blessed to their brave men, whom they call heroes and demi-gods; and to the souls of the wicked, the region of the ungodly, in Hades, where their fables relate that certain persons, such as Sisyphus, and Tantalus, and Ixion, and Tityus, are punished; which is built on this first supposition, that souls are immortal; and thence are those exhortations to virtue and dehortations from wickedness collected; whereby good men are bettered in the conduct of their life by the hope they have of reward after their death; and whereby the vehement inclinations of bad men to vice are restrained, by the fear and expectation they are in, that although they should lie concealed in this life, they should suffer immortal punishment after their death. These are the Divine doctrines of the Essens ¹ about the soul, which lay an unavoidable bait for such as have once had a taste of their philosophy.
