Again, if the world is destroyed, it must needs either be destroyed according to nature or against nature. Against nature is impossible, for that which is against nature is not stronger than nature. If according to nature, there must be another nature which changes the nature of the world: which does not appear.
4th-century Roman philosopher and writer
Sallustius or Sallust (Σαλούστιος) was a 4th-century Latin writer, a friend of the Roman Emperor Julian. He wrote the treatise On the Gods and the Cosmos, which owes much to the work of Iamblichus of Chalcis, who synthesized Platonism with Pythagoreanism and theurgy, as well as to Julian's own philosophical writings. Though uncertainty remains, and some have identified him with the praetorian prefect of Gaul, Flavius Sallustius, he is widely thought to have been Saturninius Secundus Salutius, praetorian prefect of the Orient in 361, who declined the army's offer to become Emperor after the death of Julian, after which Jovian accepted the position.

Next in order comes knowledge of the first cause and the subsequent orders of the Gods, then the nature of the world, the essence of intellect and of soul, then providence, fate, and fortune, then to see virtue and formed from them, and from what possible source evil came into the world. Each of these subjects needs many long discussions; but there is perhaps no harm in stating them briefly, so that a disciple may not be completely ignorant about them. It is proper to the first cause to be one — for unity precedes multitude — and to surpass all things in power and goodness. Consequently all things must partake of it. For owing to its power nothing else can hinder it, and owing to its goodness it will not hold itself apart. If the first cause were soul, all things would possess soul. If it were mind, all things would possess mind. If it were being, all things would partake of being. And seeing this quality in all things, some men have thought that it was being. Now if things simply were, without being good, this argument would be true, but if things that are are because of their goodness, and partake in the good, the first thing must needs be both beyond-being and good. It is strong evidence of this that noble souls despise being for the sake of the good, when they face death for their country or friends or for the sake of virtue. — After this inexpressible power come the orders of the Gods.
Of myths some are theological, some physical, some psychic, and again some material, and some mixed from these last two. The theological are those myths which use no bodily form but contemplate the very essence of the Gods: e.g., Kronos swallowing his children. Since god is intellectual, and all intellect returns into itself, this myth expresses in allegory the essence of god. Myths may be regarded physically when they express the activities of the Gods in the world: e.g., people before now have regarded Kronos as time, and calling the divisions of time his sons say that the sons are swallowed by the father. The psychic way is to regard the activities of the soul itself; the soul's acts of thought, though they pass on to other objects, nevertheless remain inside their begetters. The material and last is that which the Egyptians have mostly used, owing to their ignorance, believing material objects actually to be Gods, and so calling them: e.g., they call the earth Isis, moisture Osiris, heat Typhon, or again, water Kronos, the fruits of the earth Adonis, and wine Dionysus. To say that these objects are sacred to the Gods, like various herbs and stones and animals, is possible to sensible men, but to say that they are Gods is the notion of madmen — except, perhaps, in the sense in which both the orb of the sun and the ray which comes from the orb are colloquially called "the sun".
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?
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.
The doctrine of virtue and vice depends on that of the soul. When the irrational soul enters into the body and immediately produces fight and desire, the rational soul, put in authority over all these, makes the soul tripartite, composed of reason, fight, and desire. Virtue in the region of reason is wisdom, in the region of fight is courage, in the region of desire is temperance; the virtue of the whole soul is righteousness. It is for reason to judge what is right, for fight in obedience to reason to despise things that appear terrible, for desire to pursue not the apparently desirable, but, that which is with reason desirable. When these things are so, we have a righteous life; for righteousness in matters of property is but a small part of virtue. And thus we shall find all four virtues in properly trained men, but among the untrained one may be brave and unjust, another temperate and stupid, another prudent and unprincipled. Indeed, these qualities should not be called virtues when they are devoid of reason and imperfect and found in irrational beings. Vice should be regarded as consisting of the opposite elements. In reason it is folly, in fight, cowardice, in desire, intemperance, in the whole soul, unrighteousness. The virtues are produced by the right social organization and by good rearing and education, the vices by the opposite.
Souls that have lived in virtue are in general happy, and when separated from the irrational part of their nature, and made clean from all matter, have communion with the gods and join them in the governing of the whole world. Yet even if none of this happiness fell to their lot, virtue itself, and the joy and glory of virtue, and the life that is subject to no grief and no master are enough to make happy those who have set themselves to live according to virtue and have achieved it.
It is not unlikely, too, that the rejection of God is a kind of punishment: we may well believe that those who knew the Gods and neglected them in one life may in another life be deprived of the knowledge of them altogether. Also those who have worshipped their own kings as gods have deserved as their punishment to lose all knowledge of God.
Souls are punished when they have gone forth from the body, some wandering among us, some going to hot or cold places of the earth, some harassed by spirits. Under all circumstances they suffer with the irrational part of their nature, with which they also sinned. For its sake there subsists that shadowy body which is seen about graves, especially the graves of evil livers.
It is the natural duty of souls to do their work in the body; are we to suppose that when once they leave the body they spend all eternity in idleness? Again, if the souls did not again enter into bodies, they must either be infinite in number or God must constantly be making new ones. But there is nothing infinite in the world; for in a finite whole there cannot be an infinite part. Neither can others be made; for everything in which something new goes on being created, must be imperfect. And the world, being made by a perfect author, ought naturally to be perfect.
Suppose it is said that there are evil spirits: — if they have their power from the Gods, they cannot be evil; if from elsewhere, the Gods do not make all things. If they do not make all things, then either they wish to or cannot, or they can and do not wish; neither of which is consistent with the idea of god. We may see, therefore, from these arguments, that there is no positive evil in the world. It is in the activities of men that the evils appear, and that not of all men nor always.
