And as in processions, what comes first passes by quickly and escapes the sight; and as in torrents, the stream which is hurried by outruns, by its swiftness and rapidity, the comprehension of man, so likewise do the affairs of life, being rapidly borne onwards, and passing by swiftly, appear indeed, to be stationary, but in fact, do not stand still a moment, but are continually being dragged onwards. And men awake too, who, as far as the uncertain character of their comprehensions goes, are in no respect different from people asleep, deceiving themselves, think themselves competent to contemplate the nature of things with reasoning powers which cannot err; in whose case every one of their external senses is a hindrance to knowledge, being hurried by spectacles, and by peculiarities of flavours or odours, to which they incline, and by which they are perverted, and in
 
consequence of which they prevent any part of the soul from being in a sound state, and from advancing without stumbling as if along a level road. And humble pride, and great littleness, and all other similar states which are made up of inequality and anomaly, compel men to walk in a sort of giddiness, and create great dizziness and perplexity.
 Since, then, life is full of all this irregularity, and confusion, and indistinctness, it is necessary that the statesman as well as the philosopher should approach the science of the interpretation of dreams, so as to understand the dreams and visions which appear by day to people who believe themselves to be awake, being guided by probable conjectures and rational probabilities, and in this way he must explain each separate one, and show that such and such a thing is honourable, another disgraceful, that this is good or that is bad; that this thing is just, that thing is on the contrary unjust; and so on in the same way with respect to prudence, and courage, and piety, and holiness, and expediency, and usefulness; and in like manner of the opposite things, with respect to what was not useful nor reasonable, what was ignoble, impious, unholy, inexpedient, pernicious, and selfish.
 Moreover, he warns you in this way: is this something belonging to another? do not covet it. Is it your own? use it as not using it. Have you great abundance? share it with others; for the beauty of riches is not in the purse, but in the power it gives one to succour those who are in need. Have you but little? do not envy those who have much; no one will pity a poor man who is always envious. Are you in high reputation, and are you held in much honour? be not insolent on that account. Are you lowly in your fortunes? still let not your spirit be depressed. Does everything succeed with you according to your wish? fear a change. Do you often stumble? hope for good fortune hereafter; for the changes of human affairs are apt to be in a direction opposite to the course they have formerly taken.
 The moon and the sun, indeed, and the whole of the heaven has clearness bright and distinct, inasmuch as all things are alike which exist permanently in the heaven; and as they are all measured by the rules of truth itself, in harmonious order and in the most admirable agreement. But
 
as for earthly things, which are full of great disorder and confusion, they are inharmonious and discordant, to speak with perfect correctness, so that dense darkness has overtaken some of them, while others resemble the most brilliant light, or rather they are themselves the clearest and purest of light.
