De Aeternitate Mundi

In every uncertain and important business it is proper to invoke God, because he is the good Creator of the world, and because nothing is uncertain with him who is possessed of the most accurate knowledge of all things. But of all times it is most necessary to invoke him when one is preparing to discuss the incorruptibility of the world; for neither among the things which are visible to the outward senses is there anything more admirably complete than the world, nor among things appreciable by the intellect is there anything more perfect than God. But the mind is at all times the governor of the outward sense, and that which is appreciable by the intellect is at all times superior to that which is visible to the outward senses, but those persons in whom there is implanted a vigorous and earnest love of truth willingly undergo the trouble of making inquiries relative to the subordinate things, from that which is superior to and the ruler over them.

If then, we, who have been practised and trained in all the doctrines of prudence, and temperance, and virtue, have discarded all the stains of the passions and diseases, perhaps God would not disdain to give to souls completely purified and cleansed, so as to appear in his image, a knowledge of heavenly things either by means of dreams, or of oracles, or of signs, or of wonders. But since we have on us the marks of folly, and injustice, and of all other vices strongly stamped upon us and difficult to be effaced, we must be content even if we are only able by them to discover some faint copy and imitation of the truth.

It is right, therefore, for those who are investigating the question whether the world is perishable, since the two words, "corruption," and "the world," will be in continual use, first of all to investigate the precise meaning of both expressions, in order that we may know what is now signified, and what has been ordained. And we must enumerate, not indeed everything which is signified by those words, but so much as is useful for the purpose of our present instruction.

The world, therefore, is spoken of in its primary sense

And the term corruption is used to signify a change for the worse; it is also used to signify the utter destruction of that which exists, a destruction so complete as to have no existence at all; for as nothing is generated out of nothing, so neither can anything which exists be destroyed so as to become non-existence. [*](This is similar to Lucretius’s doctrine- Nil igitur fieri de nihilo posse putandum est. ) For it is impossible that anything should be generated of that which has no existence anywhere, as equally so that what does exist should be so utterly destroyed as never to be mentioned or heard of again. And indeed in this spirit the tragedian says:— "Nought that e’er has been Completely dies, but things combined Before another union find; Quitting their former company, And so again in other forms are seen." [*](From the Chrysippus of Euripides. )

Nor is it so very silly a thing to doubt whether the world is destroyed so as to pass into a state of non-existence, but rather whether it is subjected to a change from a new arrangement, being dissolved as to all the manifold forms of its elements and combinations so as to assume one and the same appearance, or whether, like a thing broken and dashed to pieces, it is subjected to a complete confusion of its different fragments. [*](This is similar to Lucretius’s doctrine- Nil igitur fieri de nihilo posse putandum est. ) [*](From the Chrysippus of Euripides. )

And there are three different opinions on the subject which we are at present discussing. Since some persons affirm that the world is eternal, and uncreated, and not liable to any destruction; while others, on the contrary, say that it has been created and is destructible. There are also others who take a portion of each of these two opinions, agreeing with the last-mentioned sect that it has been created, but with the former class that it is indestructible; and thus they have left behind them a mixed opinion, thinking that it is at the same time created and imperishable.

However, Democritus and Epicurus, and the principal number of the Stoic philosophers, affirm both the creation and the destructibility of the world, though they do not all speak in similar senses; for some give a sketch of many worlds, the generation of which they attribute to the concourse and combination of atoms, and their destruction they impute to the dissolution and breaking up of the combined particles. But the Stoics speak of one world only, and affirm that God is the cause of its creation, but that the cause of its corruption is no longer God, but the power of invincible, unwearied fire, which pervades all existing things, in the long periods of time dissolving everything into itself, while from it again a regeneration of the world takes place through the providence of the Creator.

And according to these men there may be one world spoken of as eternal and another as destructible, destructible in reference to its present arrangement, and eternal as to the conflagration which takes place, since it is rendered immortal by regenerations and periodical revolutions which never cease.

But Aristotle, with a knowledge as to which I know not to what degree I may call it holy and pious, affirmed that the world was uncreated and indestructible, and he accused those who maintained a contrary opinion of terrible impiety, for thinking that so great a visible God was in no respect different from things made with hands, though he contains within himself the sun, and the moon, and all the rest of the planets and fixed stars, and, in fact, the whole of the divine nature;
