All the philosophers thought matter eternal but the arts appear new. There is not one, even to the art of making bread, which is not recent. The first Romans ate pap; and these conquerors of so many nations never thought of either windmills or watermills. This truth seems at first to contradict the antiquity of the globe such as it is, or supposes terrible revolutions in this globe. The inundations of barbarians can hardly annihilate arts which have become necessary. I suppose that an army of negroes come among us like locusts, from the mountains of Cobonas, through the Monomotapa, the Monoemugi, the Nosseguais, the Maracates; that they have traversed Abyssinia, Nubia, Egypt, Syria, Asia Minor, the whole of our Europe; that they have overthrown everything, ransacked everything; there will still remain a few bakers, a few cobblers, a few tailors, a few carpenters: the necessary arts will survive; only luxury will be annihilated. It is what was seen at the fall of the Roman Empire; the art of writing even became very rare; almost all those which contributed to the comfort of life were reborn only long after. We invent new ones every day.
From all this one can at bottom conclude nothing against the antiquity of the globe. For, supposing even that an influx of barbarians had made us lose entirely all the arts even to the arts of writing and making bread; supposing, further, that for ten years past we had no bread, pens, ink and paper; the land which has been able to subsist for ten years without eating bread and without writing its thoughts, would be able to pass a century, and a hundred thousand centuries without these aids.
It is quite clear that man and the other animals can exist very well without bakers, without novelists, and without theologians, witness the whole of America, witness three quarters of our continent.
The newness of the arts among us does not therefore prove the newness of the globe, as was claimed by Epicurus, one of our predecessors in reverie, who supposed that by chance the eternal atoms in declining, had one day formed our earth. Pomponace said: "Se il mondo non è eterno, per tutti santi è molto vecchio."
ASTROLOGY
Astrology may rest on better foundations than Magic. For if no one has seen either Goblins, or Lemures, or Dives, or Peris, or Demons, or Cacodemons, the predictions of astrologers have often been seen to succeed. If of two astrologers consulted on the life of a child and on the weather, one says that the child will live to manhood, the other not; if one announces rain, and the other fine weather, it is clear that one of them will be a prophet.
The great misfortune of the astrologers is that the sky has changed since the rules of the art were established. The sun, which at the equinox was in Aries in the time of the Argonauts, is to-day in Taurus; and the astrologers, to the great ill-fortune of their art, to-day attribute to one house of the sun what belongs visibly to another. However, that is not a demonstrative reason against astrology. The masters of the art deceive themselves; but it is not demonstrated that the art cannot exist.
There is no absurdity in saying: Such and such a child is born in the waxing of the moon, during stormy weather, at the rising of such and such star; his constitution has been feeble, and his life unhappy and short; which is the ordinary lot of poor constitutions: this child, on the contrary, was born when the moon was full, the sun strong, the weather calm, at the rising of such and such star; his constitution has been good, his life long and happy. If these observations had been repeated, if they had been found accurate, experience would have been able after some thousands of years to form an art which it would have been difficult to doubt: one would have thought, with some likelihood, that men are like trees and vegetables which must be planted and sown only in certain seasons. It would have been of no avail against the astrologers to say: My son was born at a fortunate time, and nevertheless died in his cradle; the astrologer would have answered: It often happens that trees planted in the proper season perish; I answered to you for the stars, but I did not answer for the flaw of conformation you communicated to your child. Astrology operates only when no cause opposes itself to the good the stars can do.
