CHAPTER III. All, therefore, that have ever touched upon theology, have called things first, according to nature, Gods; and have said that the theological science is conversant about these. And some, indeed, have considered a corporeal essence, as that alone which has any existence, and have placed in a secondary rank with respect to essence, all the genera of incorporeal natures, considering the principles of things as having a corporeal form, and evincing that the habit in us by which we know these, is corporeal. But others, suspending indeed all bodies from incorporeal natures, and defining the first hyparxis[86] to be in soul, and the powers of soul, call (as it appears to me) the best of souls, Gods; and denominate the science which proceeds as far as to these, and which knows these, theology. But such as produce the multitude of souls from another more ancient principle, and establish intellect as the leader of wholes, these assert that the best end is a union of the soul with intellect, and consider the intellectual form of life as the most honourable of all things. They doubtless too consider theology, and the discussion of intellectual essence, as one and the same. All these, therefore, as I have said, call the first and most self-sufficient principles of things, Gods, and the science respecting these, theology. The divine narration however, of Plato alone, despises all corporeal natures, with reference to principles. Because, indeed, every thing divisible and endued with interval, is naturally unable either to produce or preserve itself, but possesses its being, energy, and passivity through soul, and the motions which soul contains. But Plato demonstrates that the psychical essence [i.e. the essence pertaining to soul] is more ancient than bodies, but is suspended from an intellectual hypostasis. For every thing which is moved according to time, though it may be self-moved, is indeed of a more ruling nature than things moved by others, but is posterior to an eternal motion. He shows, therefore, as we have said, that intellect is the father and cause of bodies and souls, and that all things both subsist and energize about it, which are allotted a life conversant with transitions and evolutions.
