Such was the origin of the word Religion, which has made so much noise in the world. After having admitted the existence of these invisible Agencies, men worshipped them to depreciate their anger, and moreover they believed that nature was under the control of these Powers. Afterwards they came to regard themselves as inert matter, or as slaves who could only act under the commands of these imaginary beings. This false idea having obtained possession of their minds, they began to exhibit more contempt for nature, and more respect for those whom they called their Gods. Hence sprung that ignorance in which so many nations were immersed--an ignorance from which, however profound, the true philosophers might have freed them, if they had not been always thwarted by those who led the blind, and throve by their own impostures. Now, although there were little appearance of success in our undertaking, we must not forsake the cause of truth. A generous mind will speak of things as they really are, out of regard to those who exhibit symptoms of this malady. The truth, whatever its nature may be, can never be injurious; whereas error, although at the time apparently innocent and even useful, must finally terminate in the most disastrous results. § 2. Terror having thus created the Gods, men wished to ascertain their nature, and conceiving that they must be of the same substance as the Soul, which they thought was like the appearances in a mirror, or the phantoms of sleep, they believed that their Gods were real substances, but so thin and subtle that to distinguish them from Bodies they named them Spirits; although Bodies and Spirits are in truth one and the same thing, for it is impossible to imagine an incorporeal Spirit. Every spirit has its proper shape, which is inclosed in some body; that is, it has its limits, and consequently it is a body, however subtle its nature. [33] § 3.
