Do not waste the remainder of thy life in thoughts about others, when thou dost not refer thy thoughts to some object of common utility. For thou losest the opportunity of doing something else when thou hast such thoughts as these, What is such a person doing, and why, and what is he saying, and what is he thinking of, and what is he contriving, and whatever else of the kind makes us wander away from the observation of our own ruling power. We ought then to check in the series of our thoughts everything that is without a purpose and useless, but most of all the over-curious feeling and the malignant; and a man should use himself to think of those things only about which if one should suddenly ask, What hast thou now in thy thoughts? With perfect openness thou mightest, immediately answer, This or That; so that from thy words it should be plain that everything in thee is simple and benevolent, and such as befits a social animal, and one that cares not for thoughts about pleasure or sensual enjoyments at all, nor has any rivalry or envy and suspicion, or anything else for which thou wouldst blush if thou shouldst say that thou hadst it in thy mind. For the man who is such and no longer delays being among the number of the best, is like a priest and minister of the gods, using too the deity which is planted within him, which makes the man uncontaminated by pleasure, unharmed by any pain, untouched by any insult, feeling no wrong, a fighter in the noblest fight, one who cannot be overpowered by any passion, dyed deep with justice, accepting with all his soul everything which happens and is assigned to him as his portion; and not often, nor yet without great necessity and for the general interest, imagining what another says, or does, or thinks. For it is only what belongs to himself that he makes the matter for his activity; and he constantly thinks of that which is allotted to himself out of the sum total of things, and he makes his own acts fair, and he is persuaded that his own portion is good. For the lot which is assigned to each man is carried along with him and carries him along with it. And he remembers also that every rational animal is his kinsman, and that to care for all men is according to man's nature; and a man should hold on to the opinion not of all, but of those only who confessedly live according to nature. But as to those who live not so, he always bears in mind what kind of men they are both at home and from home, both by night and by day, and what they are, and with what men they live an impure life. Accordingly, he does not value at all the praise which comes from such men, since they are not even satisfied with themselves.
Occupy thyself with few things, says the philosopher, if thou wouldst be tranquil.- But consider if it would not be better to say, Do what is necessary, and whatever the reason of the animal which is naturally social requires, and as it requires. For this brings not only the tranquility which comes from doing well, but also that which comes from doing few things. For the greatest part of what we say and do being unnecessary, if a man takes this away, he will have more leisure and less uneasiness. Accordingly on every occasion a man should ask himself, Is this one of the unnecessary things? Now a man should take away not only unnecessary acts, but also, unnecessary thoughts, for thus superfluous acts will not follow after.
The words which were formerly familiar are now antiquated: so also the names of those who were famed of old, are now in a manner antiquated, Camillus, Caeso, Volesus, Leonnatus, and a little after also Scipio and Cato, then Augustus, then also Hadrian and Antoninus. For all things soon pass away and become a mere tale, and complete oblivion soon buries them. And I say this of those who have shone in a wondrous way. For the rest, as soon as they have breathed out their breath, they are gone, and no man speaks of them. And, to conclude the matter, what is even an eternal remembrance? A mere nothing. What then is that about which we ought to employ our serious pains? This one thing, thoughts just, and acts social, and words which never lie, and a disposition which gladly accepts all that happens, as necessary, as usual, as flowing from a principle and source of the same kind.
Death is a cessation of the impressions through the senses, and of the pulling of the strings which move the appetites, and of the discursive movements of the thoughts, and of the service to the flesh.
How can our principles become dead, unless the impressions (thoughts) which correspond to them are extinguished? But it is in thy power continuously to fan these thoughts into a flame. I can have that opinion about anything, which I ought to have. If I can, why am I disturbed? The things which are external to my mind have no relation at all to my mind.- Let this be the state of thy affects, and thou standest erect. To recover thy life is in thy power. Look at things again as thou didst use to look at them; for in this consists the recovery of thy life.
Look round at the courses of the stars, as if thou wert going along with them; and constantly consider the changes of the elements into one another; for such thoughts purge away the filth of the terrene life.
Everywhere and at all times it is in thy power piously to acquiesce in thy present condition, and to behave justly to those who are about thee, and to exert thy skill upon thy present thoughts, that nothing shall steal into them without being well examined.
Neither in thy actions be sluggish nor in thy conversation without method, nor wandering in thy thoughts, nor let there be in thy soul inward contention nor external effusion, nor in life be so busy as to have no leisure.
There are four principal aberrations of the superior faculty against which thou shouldst be constantly on thy guard, and when thou hast detected them, thou shouldst wipe them out and say on each occasion thus: this thought is not necessary: this tends to destroy social union: this which thou art going to say comes not from the real thoughts; for thou shouldst consider it among the most absurd of things for a man not to speak from his real thoughts.
