X. (50) And he takes Milcah for his wife, not being some queen who by the dispensations of fortune governs some nation of men, or some city, but only one who bears a common name, the same as here. For, just as a person would not be widely wrong who called the world, as being the most excellent of all created things, the king of the objects of the external sense; so, also, one may call the knowledge which is conversant about the heaven, which knowledge those who study astronomy and the Chaldaeans possess in an eminent degree, the queen of all the sciences. (51) This, therefore, is the wife who is a citizen; but the concubine is she who sees one only of all existing things at a time, even though it may be the most worthless of all. It is given, therefore, to the most excellent race to see the most excellent of things, namely, the really living God; for the name Israel, being interpreted, means “seeing God.” But to him who aims at the second prize, it is allowed to see that which is second best, namely, the heaven which is perceptible by the external senses, and the harmonious arrangement of the stars therein, and their truly musical and wellregulated motion. (52) The third class are the sceptics, who do not apply themselves to the most excellent objects, either of the intellect or of the external senses, which exist in nature, because they are always occupying themselves with petty sophistries, and small cavils, and criticisms. These have for their companions the concubine Rumah, who sees something which is very minute, because they are unable to approach the investigation of better things, by means of which they might benefit their own life. (53) For, as among physicians that which is called theoretical medical skill, is a long way from doing any good to those that are sick–for diseases are cured by medicines, and by operations, and by regimen, and not by discussions or theories; so also in philosophy, there is a set of word-traffickers and word-eaters, who have neither the will nor the skill to heal a life which is full of infirmities, but who, from their very earliest infancy to the extremity of old age, are not ashamed to cavil, and quibble, and wrangle about figurative expressions, as if happiness consisted in an interminable and profitless minuteness of accuracy in the matter of nouns and verbs, and not in the improving and ameliorating the moral character, the true fountain of the persons’ disposition; and in expelling the vices, and driving them out of its boundaries, and establishing the virtues as settlers within them.
