Chapter XXII.—The Light of the Moon from the Sun; The Inconvenience of the Opinion that Souls are Received in It; The Two Deluges of the Greeks. Now, they say that the sun and the moon having by degrees separated the divine virtue from matter, transmit it to God. But if they had only to a slight degree frequented the schools of the astronomers, it would not have happened to them to fall into these fancies, nor would they have been ignorant that the moon, which, according to the opinion of some, is itself without light, receives its light from the sun, and that its configurations are just in proportion to its distance from the sun, and that it is then full moon when it is distant from the sun one hundred and eighty degrees. It is in conjunction when it is in the same degree with the sun. Then, is it not wonderful how it comes to pass that there should be so many souls, and from such diverse creatures? For there is the soul of the world itself, and of the animals, of plants, of nymphs, and demons, and amongst these are distinguished by appearance those of fowls, of land animals, and animals amphibious; but in the moon one like body is always seen by us. And what of the continuity of this body? When the moon is half-full, it appears a semicircle, and when it is in its third quarter, the same again. How then, and with what figure, are they assumed into the moon? For if it be light as fire, it is probable that they would not only ascend as far as the moon, but even higher, continually; but if it be heavy, it would not be possible for them at all to reach the moon. And what is the reason that that which first arrives at the moon is not immediately transmitted to the sun, but waits for the full moon until the rest of the souls arrive? When then the moon, from having been full, decreases, where does the virtue remain during that time? until the moon, which has been emptied of the former souls, just as a desolated city, shall receive again a fresh colony. For a treasure-house should have been marked out in some part of the earth, or of the clouds, or in some other place, where the congregated souls might stand ready for emigration to the moon. But, again, a second question arises. What then is the cause that it is not full immediately? or why does it again wait fifteen days? Nor is this less to be wondered at than that which has been said, that never within the memory of man has the moon become full after the fifteen days. Nay, not even—in the time of the deluge of Deucalion, nor in that of Phoroneus, when all things, so to speak, which were upon the face of the earth perished, and it happened that a great quantity of virtue was separated from matter. And, besides these things, one must consider the productiveness of generations, and their barrenness, and also the destruction of them; and since these things do not happen in order, neither ought the order of the full moon, nor the these of the waning moon, to be so carefully observed.
