The doctrines of judicial astrology and magic have spread all over the world. Look back to the ancient Zoroaster, and you will find that of the genii long established. All antiquity abounds in astrologers and magicians; such ideas were therefore very natural. At present, we smile at the number who entertained them; if we were in their situation, if like them we were only beginning to cultivate the sciences, we should perhaps believe just the same. Let us suppose ourselves intelligent people, beginning to reason on our own existence, and to observe the stars. The earth, we might say, is no doubt immovable in the midst of the world; the sun and planets only revolve in her service, and the stars are only made for us; man, therefore, is the great object of all nature. What is the intention of all these globes, and of the immensity of heaven thus destined for our use? It is very likely that all space and these globes are peopled with substances, and since we are the favorites of nature, placed in the centre of the universe, and all is made for man, these substances are evidently destined to watch over man. The first man who believed the thing at all possible would soon find disciples persuaded that it existed. We might then commence by saying, genii perhaps exist, and nobody could affirm the contrary; for where is the impossibility of the air and planets being peopled? We might afterwards say there _are_ genii, and certainly no one could prove that there are not. Soon after, some sages might see these genii, and we should have no right to say to them: "You have not seen them"; as these persons might be honorable, and altogether worthy of credit. One might see the genius of the empire or of his own city; another that of Mars or Saturn; the genii of the four elements might be manifested to several philosophers; more than one sage might see his own genius; all at first might be little more than dreaming, but dreams are the symbols of truth. It was soon known exactly how these genii were formed. To visit our globe, they must necessarily have wings; they therefore had wings. We know only of bodies; they therefore had bodies, but bodies much finer than ours, since they were genii, and much lighter, because they came from so great a distance. The sages who had the privilege of conversing with the genii inspired others with the hope of enjoying the same happiness. A skeptic would have been ill received, if he had said to them: "I have seen no genius, therefore there are none." They would have replied: "You reason ill; it does not follow that a thing exists not, which is unknown to you. There is no contradiction in the doctrine which inculcates these ethereal powers; no impossibility that they may visit us; they show themselves to our sages, they manifest themselves to us; you are not worthy of seeing genii."
