a man have any apprehension about the change and dissolution of all the elements [himself]? for it is according to nature; and nothing is evil that is according to nature.”
The Physic of Antoninus is the knowledge of the Nature of the Universe, of its government, and of the relation of man’s nature to both. He names the universe (VI. 1), “the universal substance,” and he adds that “reason” governs the universe. He also (VI. 9) uses the terms “universal nature” or “nature of the universe.” He (VI. 25) calls the universe “the one and all, which we name Cosmos or Order.” If he ever seems to use these general terms as significant of the All, of all that man can in any way conceive to exist, he still on other occasions plainly distinguishes between Matter, Material things, and Cause, Origin, Reason. This is conformable to Zeno’s doctrine that there are two original principles of all things, that which acts and that which is acted upon. That which is acted on is the formless matter: that which acts is the reason, God, who is eternal and operates through all matter, and produces all things. So Antoninus (V. 32) speaks of the reason which pervades all substance, and through all time by fixed periods (revolutions) administers the universe. God is eternal, and Matter is eternal. It is God who gives form to matter, but he is not said to have created matter. According to this view, which is as old as Anaxagoras, God and matter exist independently, but God governs matter. This doctrine is simply the expression of the fact of the existence both of matter and of God. The Stoics did not perplex themselves with the insoluble question of the origin and nature of matter. Antoninus also assumes a beginning of things, as we now know them; but his language is sometimes very obscure.
Matter consists of elemental parts of which all material objects are made. But nothing is permanent in form. The nature of the universe, according to Antoninus’ expression (IV. 36), “loves nothing so much as to change the things which are, and to make new things like them. For everything that exists is in a manner the seed of that which will be. But thou art thinking only of seeds which are cast into the earth or into a womb: but this is a very vulgar notion.” All things then are in a constant flux and change: some things are dissolved into the elements, others come in their places; and so the “whole universe continues ever young and perfect.”
When we look at the motions of the planets, the action of what we call gravitation, the elemental combination of unorganized bodies and their resolution, the production of plants and of living bodies, their generation, growth, and their dissolution, which we call their death, we observe a regular sequence of phenomena, which within the limits of experience present and past, so far as we know the past, is fixed and invariable. But if this is not so, if the order and sequence of phenomena, as known to us, are subject to change in the course of an infinite progression,—and such change is conceivable,—we have not discovered, nor shall we ever discover, the whole of the order and sequence of phenomena, in which sequence there may be involved according to its very nature, that is, according to its fixed order, some variation of what we now call the Order or Nature of Things. It is also conceivable that such changes have taken place,—changes in the order of things, as we are compelled by the imperfection of language to call them, but which are no changes; and further it is certain that our knowledge of the true sequence of all actual phenomena, as for instance the phenomena of generation, growth, and dissolution, is and ever must be imperfect.
