Be not disgusted, nor discouraged, nor dissatisfied, if thou dost not succeed in doing everything according to right principles; but when thou bast failed, return back again, and be content if the greater part of what thou doest is consistent with man's nature, and love this to which thou returnest; and do not return to philosophy as if she were a master, but act like those who have sore eyes and apply a bit of sponge and egg, or as another applies a plaster, or drenching with water. For thus thou wilt not fail to obey reason, and thou wilt repose in it. And remember that philosophy requires only the things which thy nature requires; but thou wouldst have something else which is not according to nature.- It may be objected, Why what is more agreeable than this which I am doing?- But is not this the very reason why pleasure deceives us? And consider if magnanimity, freedom, simplicity, equanimity, piety, are not more agreeable. For what is more agreeable than wisdom itself, when thou thinkest of the security and the happy course of all things which depend on the faculty of understanding and knowledge?
Let the part of thy soul which leads and governs be undisturbed by the movements in the flesh, whether of pleasure or of pain; and let it not unite with them, but let it circumscribe itself and limit those affects to their parts. But when these affects rise up to the mind by virtue of that other sympathy that naturally exists in a body which is all one, then thou must not strive to resist the sensation, for it is natural: but let not the ruling part of itself add to the sensation the opinion that it is either good or bad.
Take pleasure in one thing and rest in it, in passing from one social act to another social act, thinking of God.
How many pleasures have been enjoyed by robbers, patricides, tyrants.
He who loves fame considers another man's activity to be his own good; and he who loves pleasure, his own sensations; but he who has understanding, considers his own acts to be his own good.
Thou hast not leisure or ability to read. But thou hast leisure or ability to check arrogance: thou hast leisure to be superior to pleasure and pain: thou hast leisure to be superior to love of fame, and not to be vexed at stupid and ungrateful people, nay even to care for them.
Repentance is a kind of self-reproof for having neglected something useful; but that which is good must be something useful, and the perfect good man should look after it. But no such man would ever repent of having refused any sensual pleasure. Pleasure then is neither good nor useful.
Whatever man thou meetest with, immediately say to thyself: What opinions has this man about good and bad? For if with respect to pleasure and pain and the causes of each, and with respect to fame and ignominy, death and life, he has such and such opinions, it will seem nothing wonderful or strange to me, if he does such and such things; and I shall bear in mind that he is compelled to do so.
Everything exists for some end, a horse, a vine. Why dost thou wonder? Even the sun will say, I am for some purpose, and the rest of the gods will say the same. For what purpose then art thou? to enjoy pleasure? See if common sense allows this.
Does Panthea or Pergamus now sit by the tomb of Verus? Does Chaurias or Diotimus sit by the tomb of Hadrian? That would be ridiculous. Well, suppose they did sit there, would the dead be conscious of it? And if the dead were conscious, would they be pleased? And if they were pleased, would that make them immortal? Was it not in the order of destiny that these persons too should first become old women and old men and then die? What then would those do after these were dead? All this is foul smell and blood in a bag.
In the constitution of the rational animal I see no virtue which is opposed to justice; but I see a virtue which is opposed to love of pleasure, and that is temperance.
Hindrance to the perceptions of sense is an evil to the animal nature. Hindrance to the movements (desires) is equally an evil to the animal nature. And something else also is equally an impediment and an evil to the constitution of plants. So then that which is a hindrance to the intelligence is an evil to the intelligent nature. Apply all these things then to thyself. Does pain or sensuous pleasure affect thee? The senses will look to that.- Has any obstacle opposed thee in thy efforts towards an object? if indeed thou wast making this effort absolutely (unconditionally, or without any reservation), certainly this obstacle is an evil to thee considered as a rational animal. But if thou takest into consideration the usual course of things, thou hast not yet been injured nor even impeded. The things however which are proper to the understanding no other man is used to impede, for neither fire, nor iron, nor tyrant, nor abuse, touches it in any way. When it has been made a sphere, it continues a sphere.
To her who gives and takes back all, to nature, the man who is instructed and modest says, Give what thou wilt; take back what thou wilt. And he says this not proudly, but obediently and well pleased with her.
When thou art offended at any man's fault, forthwith turn to thyself and reflect in what like manner thou dost err thyself; for example, in thinking that money is a good thing, or pleasure, or a bit of reputation, and the like. For by attending to this thou wilt quickly forget thy anger, if this consideration also is added, that the man is compelled: for what else could he do? or, if thou art able, take away from him the compulsion.
What is that which as to this material (our life) can be done or said in the way most conformable to reason. For whatever this may be, it is in thy power to do it or to say it, and do not make excuses that thou art hindered. Thou wilt not cease to lament till thy mind is in such a condition that, what luxury is to those who enjoy pleasure, such shall be to thee, in the matter which is subjected and presented to thee, the doing of the things which are conformable to man's constitution; for a man ought to consider as an enjoyment everything which it is in his power to do according to his own nature. And it is in his power everywhere.
Contemplate the formative principles (forms) of things bare of their coverings; the purposes of actions; consider what pain is, what pleasure is, and death, and fame; who is to himself the cause of his uneasiness; how no man is hindered by another; that everything is opinion.
