Simplicius, Commentary on Epictetus 10.3

. . . None but ignorant and undisciplined people tax others with their misfortunes. The young proficient blames himself; but he who is a philosopher indeed, blames neither others nor himself.

Comment: 

The connection of this with what went before is so close, that if a conjunction were added, and we read thus, for none but ignorant and undisciplined people tax other with their misfortunes, it would give a very good reason why we should never lay our troubles, or fears, or disorders, or any other calamity we fancy ourselves in, to anything, or anybody’s charge, but our own: since this way of proceeding, he says, comes from want of being taught better. And then to this character of the ignorant and undisciplined, he adds those of one who is a beginner only in philosophy, and one who has attained to a mastery in it. 

The perfect philosopher never thinks anything, that befalls him, evil; or charges anybody with being the occasion of his misfortunes; because he lives up to the dictates of nature and reason, and is never disappointed in his pursuits and desires, nor ever overtaken with his fears. 

He that is but raw and unfinished, does indeed sometimes miss of his desires, and fall into the mischiefs he would flee from, because the brutish inclinations move too strongly in him at such times. And when this happens, the first elements he learned, which taught him to distinguish things in and out of our power, teach him too, that he himself, and none but he, is the true cause of all his disappointments, and all his disasters. And the occasion of them all was his mistaking the things without us, and placing a man’s proper good and evil in them.

But you will say, perhaps, since this young philosopher knows, that our own proper good and evil depends upon our own power and choice (and the accusing himself implies that he knows thus much), how comes it to pass, that he takes wrong measures, and renders himself liable to this blame? 

Probably, because the knowledge of good and evil is the first step to be made toward virtue, this being the proper act of reason: but the brutish appetites do not always presently submit to reason, nor suffer themselves to be easily reduced and tempered by it; and especially, where it happens, as it does very often, that reason is negligent and sluggish, and the irrational part active, and perpetually in motion, by which means the passions gather strength, and usurp and absolute dominion. This was the case of her in the play:

Remorse and sense of guilt pull back my soul,

But stronger passion does her powers control;
With rage transported, I push boldly on,
And see the precipice I cannot shun. 

So that for some time it is pretty tolerable, if reason can work upon the passions, and either draw them by force, or charm and win them over some softer way: for, when this is done, then the knowledge of the intelligent part is more clear and instructive, and proceeds without any distraction at all. 

No wonder therefore, if men but little trained in philosophy make some false steps while their passions are not yet totally subdued, and their reason does not operate in its full strength. And when they do so, they accuse themselves only, as having admitted that distinction of things in and out of our own power, though as yet they seem to have but an imperfect notion of it. 

But they that are ignorant, and absolutely untaught, must needs commit a world of errors, both because of that violent agitation which their passions are continually in, and of the ignorance of their rational part, which has not yet learned to distinguish real good and evil, from what is so in appearance only: nor does it take them off from brutality, not so much as in thought only. By brutality I mean such low and mean notions, as persuade us, that our body is properly ourselves, and our nature; or, which is yet worse, when we think our riches so, as the covetous do. 

Now while we continue thus ignorant, there are several accounts to be given for our doing amiss: we do it, because we think all our good and evil consist in things without us; and, not being at all sensible, what is properly the happiness or unhappiness of human nature, or whence it proceeds, we fall foul upon other people; and fancy, that they, who obstruct or deprive us of those external advantages we so eagerly pursue, or that bring upon us any of the calamities we would avoid, are the real causes of all our misery. 

Though in truth, neither those external advantages which we call good, nor those calamities we call evil, are what we take them for; but, as circumstances are sometimes ordered, may prove the direct contrary. For our folly in this case is just like that of silly boys, who cannot endure their masters, but think them their worst enemies, and the cause of a world of misery, but value and love those as their friends, indeed, that invite them to play and pleasure. . . .
