That the rational soul, indeed, so far as it is rational, produces itself, may be clearly demonstrated as follows:--That which is able to impart any thing superior and more excellent in any genus of things, can easily impart that which is subordinate and less excellent in the same genus; but well being confessedly ranks higher and is more excellent than mere being. The rational soul imparts well being to itself, when it cultivates and perfects itself, and recalls and withdraws itself from the contagion of the body. It will therefore also impart being to itself. And this with great propriety; for all divine natures, and such things as possess the ability of imparting any thing primarily to others, necessarily begin this energy from themselves. Of this mighty truth the sun himself is an illustrious example; for he illuminates all things with his light, and is himself light, and the fountain and origin of all splendour. Hence, since the souls imparts life and motion to other things, on which account Aristotle calls an animal antokincton, self- moved, it will much more, and by a much greater priority, impart life and motion to itself.
From this magnificent, sublime, and most scientific doctrine of Plato, respecting the arcane principle of things and his immediate progeny, it follows that this ineffable cause is not the immediate maker of the universe, and this, as I have observed in the Introduction to the Timaeus, not through any defect, but on the contrary through transcendency of power. All things indeed are ineffably unfolded from him at once, into light; but divine media are necessary to the fabrication of the world. For if the universe was immediately produced from the ineffable, it would, agreeably to what we have above observed, be ineffable also in a secondary degree. But as this is by no means the case, it principally derives its immediate subsistence from a deity of a fabricative characteristic, whom Plato calls Jupiter, conformably to the theology of Orpheus. The intelligent reader will readily admit that this dogmas is so far from being derogatory to the dignity of the Supreme, that on the contrary it exalts that dignity, and, preserves in a becoming manner the exempt transcendency of the ineffable. If therefore we presume to celebrate him, for as we have already observed, it is more becoming to establish in silence those parturitions of the soul which dare anxiously to explore him, we should celebrate him as the principle of principles, and the fountain of deity, or in the reverential language of the Egyptians, as a darkness thrice unknown.[7] Highly laudable indeed, and worthy the imitation of all posterity, is the veneration which the great ancients paid to this immense principle. This I have already noticed in the Introduction to the Parmenides, and I shall only observe at present in addition, that in consequence of this profound and most pious reverence of the first God, they did not even venture to give a name to the summit of that highest order of divinities which is denominated intelligible. Hence, says Proclus, in his Mss. Scholia on the Cratylus, "Not every genus of the gods has an appellation; for with respect to the first Deity, who is beyond all things, Parmenides teaches us that he is ineffable; and the first genera of the intelligible gods, who are united to the one, and are called occult, have much of the unknown and ineffable. For that which is perfectly effable cannot be conjoined with the perfectly ineffable; but it is necessary that the progression of intelligibles should terminate in this order, in which the first effable subsists, and that which is called by proper names. For there the first intelligible forms, and the intellectual nature of intelligibles, are unfolded into light. But, the natures prior to this being silent and occult, are only known by intelligence. Hence the whole of the telestic science energizing theurgically ascends as far as to this order. Orpheus also says that this is first called by a name by the other gods; for the light proceeding from it is known to and denominated by the intellectual gods."
