Marcus Aurelius, Meditations, Book VIII, section 41. George Long translation.
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 (xi. 12).
From my mother, piety and beneficence, and abstinence, not only from evil deeds, but even from evil thoughts; and further, simplicity in my way of living, far removed from the habits of the rich.
From my great-grandfather, not to have frequented public schools, and to have had good teachers at home, and to know that on such things a man should spend liberally.
From my governor, to be neither of the green nor of the blue party at the games in the Circus, nor a partisan either of the Parmularius or the Scutarius at the gladiators' fights; from him too I learned endurance of labor, and to want little, and to work with my own hands, and not to meddle with…
From Diognetus, not to busy myself about trifling things, and not to give credit to what was said by miracle-workers and jugglers about incantations and the driving away of daemons and such things; and not to breed quails [for fighting], nor to give myself up passionately to such things; and to…
From Rusticus I received the impression that my character required improvement and discipline; and from him I learned not to be led astray to sophistic emulation, nor to writing on speculative matters, nor to delivering little hortatory orations, nor to showing myself off as a man who practises…
From Apollonius I learned freedom of will and undeviating steadiness of purpose; and to look to nothing else, not even for a moment, except to reason; and to be always the same, in sharp pains, on the occasion of the loss of a child, and in long illness; and to see clearly in a living example that…
From Sextus, a benevolent disposition, and the example of a family governed in a fatherly manner, and the idea of living conformably to nature; and gravity without affectation, and to look carefully after the interests of friends, and to tolerate ignorant persons, and those who form opinions…
From Alexander the grammarian, to refrain from fault-finding, and not in a reproachful way to chide those who uttered any barbarous or solecistic or strange-sounding expression; but dexterously to introduce the very expression which ought to have been used, and in the way of answer or giving…
From Fronto I learned to observe what envy and duplicity and hypocrisy are in a tyrant, and that generally those among us who are called Patricians are rather deficient in paternal affection.
From Alexander the Platonic, not frequently nor without necessity to say to any one, or to write in a letter, that I have no leisure; nor continually to excuse the neglect of duties required by our relation to those with whom we live, by alleging urgent occupations.
From Catulus not to be indifferent when a friend finds fault, even if he should find fault without reason, but to try to restore him to his usual disposition; and to be ready to speak well of teachers, as it is reported of Domitius and Athenodotus; and to love my children truly.
From my brother Severus, to love my kin, and to love truth, and to love justice; and through him I learned to know Thrasea, Helvidius, Cato, Dion, Brutus; and from him I received the idea of a polity in which there is the same law for all, a polity administered with regard to equal rights and…
From Maximus I learned self-government, and not to be led aside by anything; and cheerfulness in all circumstances, as well as in illness; and a just admixture in the moral character of sweetness and dignity, and to do what was set before me without complaining.…
In my father I observed mildness of temper, and unchangeable resolution in the things which he had determined after due deliberation; and no vain-glory in those things which men call honors; and a love of labor and perseverance; and a readiness to listen to those who had anything to propose for…
To the gods I am indebted for having good grandfathers, good parents, a good sister, good teachers, good associates, good kinsmen and friends, nearly everything good.…
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.…
Whatever this is that I am, it is a little flesh and breath, and the ruling part. Throw away thy books; no longer distract thyself: it is not allowed; but as if thou wast now dying, despise the flesh; it is blood and bones and network, a contexture of nerves, veins, and arteries.…
All that is from the gods is full of providence. That which is from fortune is not separated from nature or without an interweaving and involution with the things which are ordered by providence.…
Every moment think steadily as a Roman and a man to do what thou hast in hand with perfect and simple dignity, and feeling of affection, and freedom, and justice, and to give thyself relief from all other thoughts.…
Do wrong to thyself, do wrong to thyself, my soul; but thou wilt no longer have the opportunity of honoring thyself. Every man's life is sufficient.+ But thine is nearly finished, though thy soul reverences not itself, but places thy felicity in the souls of others.
