No longer talk at all about the kind of man that a good man ought to be, but be such. (10.16)
A cucumber is bitter—Throw it away.—There are briers in the road—Turn aside from them.—This is enough. Do not add, And why were such things made in the world? (8.50)
Soon, very soon, thou wilt be ashes, or a skeleton, and either a name or not even a name; but name is sound and echo. (5.33)
In the morning when thou risest unwillingly, let this thought be present,—I am rising to the work of a human being. Why then am I dissatisfied if I am going to do the things for which I exist and for which I was brought into the world? Or have I been made for this, to lie in the bed-clothes and keep myself warm?—But this is more pleasant.—Dost thou exist then to take thy pleasure, and not at all for action or exertion? (5.1)
Begin the morning by saying to thyself, I shall meet with the busybody, the ungrateful, arrogant, deceitful, envious, unsocial. All these things happen to them by reason of their ignorance of what is good and evil. But I who have seen the nature of the good that it is beautiful, and of the bad that it is ugly, and the nature of him who does wrong, that it is akin to me; not only of the same blood or seed, but that it participates in the same intelligence and the same portion of the divinity, I can neither be injured by any of them, for no one can fix on me what is ugly, nor can I be angry with my kinsman, nor hate him. For we are made for co-operation, like feet, like hands, like eyelids, like the rows of the upper and lower teeth. To act against one another, then, is contrary to nature; and it is acting against one another to be vexed and to turn away. (2.1)
Men seek retreats for themselves, houses in the country, sea-shores, and mountains; and thou too art wont to desire such things very much. But this is altogether a mark of the most common sort of men, for it is in thy power whenever thou shalt choose to retire into thyself. For nowhere either with more quiet or more freedom from trouble does a man retire than into his own soul, particularly when he has within him such thoughts that by looking into them he is immediately in perfect tranquillity; and I affirm that tranquillity is nothing else than the good ordering of the mind. Constantly then give to thyself this retreat, and renew thyself; and let thy principles be brief and fundamental, which, as soon as thou shalt recur to them, will be sufficient to cleanse the soul completely, and to send thee back free from all discontent with the things to which thou returnest. (4.3)
Be like the promontory against which the waves continually break, but it stands firm and tames the fury of the water around it. Unhappy am I because this has happened to me? Not so, but happy am I, though this has happened to me, because I continue free from pain, neither crushed by the present nor fearing the future. For such a thing as this might have happened to every man; but every man would not have continued free from pain on such an occasion. Why then is that rather a misfortune than this a good fortune? [...] Remember too on every occasion which leads thee to vexation to apply this principle; not that this is a misfortune, but that to bear it nobly is good fortune. (4.49)
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. (7.47)
Look within. Within is the fountain of good, and it will ever bubble up, if thou wilt ever dig. (7.59)
Remember that the ruling faculty is invincible, when self-collected it is satisfied with itself, if it does nothing which it does not choose to do, even if it resist from mere obstinacy. What then will it be when it forms a judgment about anything aided by reason and deliberately? Therefore the mind which is free from passions is a citadel, for man has nothing more secure to which he can fly for refuge and for the future be inexpugnable. (8.48)
Look down from above on the countless herds of men and their countless solemnities, and the infinitely varied voyagings in storms and calms, and the differences among those who are born, who live together, and die. And consider, too, the life lived by others in olden time, and the life of those who will live after thee, and the life now lived among barbarous nations, and how many know not even thy name, and how many will soon forget it, and how they who perhaps now are praising thee will very soon blame thee, and that neither a posthumous name is of any value, nor reputation, nor anything else. (9.30)
