It is requisite, therefore, to endeavour, with all possible earnestness and attention, that children may be born elegant and graceful, and that when born, they should be well educated. For neither is it just that those who rear horses, or birds, or dogs, should, with the utmost diligence, endeavour that the breed may be such as is proper, and from such things as are proper, and when it is proper[22]; and likewise consider how they ought to be disposed when they copulate with each other, in order that the offspring may not be a casual production;—but that men should pay no attention to their progeny, but should beget them casually; and when begotten, should neglect both their nutriment and their education: for these being disregarded, the causes of all vice and depravity are produced, since those that are thus born will resemble cattle, and will be ignoble and vile. FOOTNOTES: [8] See Additional Notes, [a]. [9] The universe could not be generated together with all things, for the principle of it must be unbegotten; since everything that is generated, is generated from a cause; and if this cause was also generated, there must be a progression of causes ad infinitum, unless the unbegotten is admitted to be the principle of the universe. Neither, therefore, can the universe be corrupted together with all things; for the principle of it being unbegotten is also incorruptible; that only being corruptible, which was once generated. [10] Critolaus, the Peripatetic, employs nearly the same arguments as those contained in this paragraph, in proof of the perpetuity of the world, as is evident from the following passage, preserved by Philo, in his Treatise Περι Αφθαρσιας Κοσμου, “On the Incorruptibility of the World”: το αιτιον αυτῳ του υγιαινειν, ανοσον εστι· αλλα και το αιτιον αυτῳ του αγρυπνειν, αγρυπνον εστιν. ει δε τουτο, και το αιτιον αυτῳ του υπαρχειν, αϊδιον εστιν. αιτιος δε ο κοσμος αυτῳ του υπαρχειν, ειγε και τοις αλλοις απασιν. αϊδιος ο κοσμος εστιν. i. e. “That which is the cause to itself of good health, is without disease. But, also, that which is the cause to itself of a vigilant energy, is sleepless. But if this be the case, that also which is the cause to itself of existence, is perpetual. The world, however, is the cause to itself of existence, since it is the cause of existence to all other things. The world, therefore, is perpetual.” Everything divine, according to the philosophy of Pythagoras and Plato, being a self-perfect essence, begins its own energy from itself, and is therefore primarily the cause to itself of that which it imparts to others. Hence, since the world, being a divine and self-subsistent essence, imparts to itself existence, it must be without non-existence, and therefore must be perpetual. [11] i. e. It is not true that the universe can contain anything greater and more powerful than itself.
