Note 1 — Chapter IV · What the word Religion signifies, and how and why such a great number have been introduced in the world.
Reading edition
After having forged these Gods they were curious to know of what matter they consisted, and finally imagined that they should be of the same substance as the soul. Then being persuaded that the latter resembled the shadows which appear in a mirror, or during sleep, they believed that some Gods were real substances but so thin and subtile that to distinguish them from bodies they called them Spirits. So that bodies and spirits were in effect the same thing, and differed neither more nor less, and to be both corporeal and incorporeal is a most incomprehensible thing. The reason given is that each spirit has a proper form, and is included within some limit, that is to say that it has some boundaries, and consequently must be a body however thin and subtile it might be.1
