Sallustius (or Sallust)

Everything that is destroyed is either destroyed by itself or by something else. If the world is destroyed by itself, fire must needs burn of itself and water dry itself. If by something else, it must be either by a body or by something incorporeal. By something incorporeal is impossible; for incorporeal things preserve bodies — nature, for instance, and soul — and nothing is destroyed by a cause whose nature is to preserve it. If it is destroyed by some body, it must be either by those which exist or by others. … But if the world is to be destroyed by other bodies than these it is impossible to say where such bodies are or whence they are to arise.

Everything made is made either by art or by a physical process or according to some power. Now in art or nature the maker must needs be prior to the made: but the maker, according to power, constitutes the made absolutely together with itself, since its power is inseparable from it; as the sun makes light, fire makes heat, snow makes cold.
Now if the Gods make the world by art, they do not make it be, they make it be such as it is. For all art makes the form of the object. What therefore makes it to be?

Thus much, my dear Sallust, upon the threefold operation of the deity have I ventured to write for you, in about three nights' space, having gone over the subject in my memory as far as it was possible: since what I had previously written to you "upon the Saturnalia" did not prove entirely labour thrown away. But on the same subject you will obtain more complete and more abstruse information by consulting the works upon it composed by the divine Iamblichus: you will find there the extreme limit of human wisdom attained. May the mighty Sun grant me to attain to no less knowledge of himself, and to teach it publicly to all, and privately to such as are worthy to receive it: and as long as the god grants this to us, let us consult in common his well-beloved Iamblichus; out of whose abundance a few things, that have come into my mind, I have here set down. That no other person will treat of this subject more perfectly than he has done, I am well aware; not even though he should expend much additional labour in making new discoveries in the research; for in all probability he will go astray from the most correct conception of the nature of the god.

While the body is young and fine, the soul blunders, but as the body grows old it attains its highest power. Again, every good soul uses mind; but no body can produce mind: for how should that which is without mind produce mind? Again, while the soul uses the body as an instrument, it is not in it; just as the engineer is not in his engines (although many engines move without being touched by any one).

If any one thinks the doctrine of the unchangeableness of the Gods is reasonable and true, and then wonders how it is that they rejoice in the good and reject the bad, are angry with sinners and become propitious when appeased, the answer is as follows: God does not rejoice — for that which rejoices also grieves; nor is he angered — for to be angered is a passion; nor is he appeased by gifts — if he were, he would be conquered by pleasure.
It is impious to suppose that the divine is affected for good or ill by human things. The Gods are always good and always do good and never harm, being always in the same state and like themselves. The truth simply is that, when we are good, we are joined to the Gods by our likeness to live according to virtue we cling to the Gods, and when we become evil we make the Gods our enemies — not because they are angered against us, but because our sins prevent the light of the Gods from shining upon us, and put us in communion with spirits of punishment. And if by prayers and sacrifices we find forgiveness of sins, we do not appease or change the Gods, but by what we do and by our turning toward the divine we heal our own badness and so enjoy again the goodness of the Gods. To say that God turns away from the evil is like saying that the sun hides himself from the blind.

If when matter is destroyed other matter takes its place, the new matter must come either from something that is or from something that is not. If from that-which-is, as long as that-which-is always remains, matter always remains. But if that-which-is is destroyed, such a theory means that not the world only but everything in the universe is destroyed.
If again matter comes from that-which-is-not: in the first place, it is impossible for anything to come from that which is not; but suppose it to happen, and that matter did arise from that which is not; then, as long as there are things which are not, matter will exist. For I presume there can never be an end of things which are not.

Now the myths represent the Gods themselves and the goodness of the Gods — subject always to the distinction of the speakable and the unspeakable, the revealed and the unrevealed, that which is clear and that which is hidden: since, just as the Gods have made the goods of sense common to all, but those of intellect only to the wise, so the myths state the existence of Gods to all, but who and what they are only to those who can understand.

The divine itself is without needs, and the worship is paid for our own benefit. The providence of the Gods reaches everywhere and needs only some congruity for its reception. All congruity comes about by representation and likeness; for which reason the temples are made in representation of heaven, the altar of earth, the images of life (that is why they are made like living things), the prayers of the element of though, the mystic letters of the unspeakable celestial forces, the herbs and stones of matter, and the sacrificial animals of the irrational life in us.
From all these things the Gods gain nothing; what gain could there be to God? It is we who gain some communion with them.
