James; and it shows us one of its poles, and the other it conceals from us; and it shows us only one motion from east to west, and another which it has from west to east, it keeps almost hidden from us. Therefore we must note in order, first its comparison with Physics, and then with Metaphysics. The Starry Heaven, I say, shows us many stars; for, according as the wise men of Egypt have computed, down to the last star that appears in their meridian, there are one thousand and twenty-two clusters of the stars I speak of. And in this it bears a great resemblance to Physics, if these three members, namely, two and twenty and a thousand, are carefully considered; for by the two is understood the local movement, which of necessity is from one point to another; and by the twenty is signified the movement of modification; for, inasmuch as from the ten upwards we proceed only by modifying this ten with the other nine, and with itself, and the most beautiful modification which it receives is that with itself, and the first which it receives is twenty, consequently the movement aforesaid is signified by this number. And by the thousand is signified the movement of increase; for in name this thousand is the greatest number, and cannot increase except by multiplying itself.
