[146] [cap.29] These things being thus previously sketched out, see now how God, dividing things in the middle, has divided them into equal portions according to all the ideas of equality which occur in the creation of the universe. He has divided the heavy things so as to make them equal in number to the light ones, two to two; that is to say, so that the earth and the water, being things of weight, are equal in number to those which are by nature light, air, and fire. Again, he has made one equal to one, the driest thing to the wettest thing, the earth to the water; and the coldest thing to the hottest thing, the air to the fire. So, in the same manner, he has divided light from darkness, and day from night, and summer from winter, and autumn from spring; and so on.
