There is a certain force, less primary than being but more primary than the soul, which draws its existence from being and completes the soul as the sun completes the eyes. Of souls some are rational and immortal, some irrational and mortal. The former are derived from the first Gods, the latter from the secondary.
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.

The soul sins therefore because, while aiming at good, it makes mistakes about the good, because it is not primary essence. And we see many things done by the Gods to prevent it from making mistakes and to heal it when it has made them. Arts and sciences, curses and prayers, sacrifices and initiations, laws and constitutions, judgments and punishments, all came into existence for the sake of preventing souls from sinning; and when they are gone forth from the body, Gods and spirits of purification cleanse them of their sins.
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.
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.
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.
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).
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.
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".
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.
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.
It is not only spirits who punish the evil, the soul brings itself to judgment: and also it is not right for those who endure for ever to attain everything in a short time: and also, there is need of human virtue. If punishment followed instantly upon sin, men would act justly from fear and have no virtue.
