Book II
Put yourself in mind, every morning, that before night you will meet with some meddlesome, ungrateful and abusive fellow, with some envious or unsociable churl.Remember that their perversity proceeds from ignorance of good and evil; and that since it has fallen to my share to understand the natural beauty of a good action and the deformity of an ill one; since I am satisfied that the disobliging person is of kin to me, our minds being both extracted from the Deity; since no man can do me a real injury because no man can force me to misbehave myself; I cannot therefore hate or be angry with one of my own nature and family. For we are all made for mutual assistance, no less than the parts of the body are for the service of the whole; whence it follows that clashing and opposition are utterly unnatural. This being of mine consists of body, breath, and that part which governs. Put away your books and face the matter itself. As for your body, value it no more than if you were just expiring; it is nothing but a little blood and bones. Your breath is but a little air pumped in and out. But the third part is your mind. Here make a stand. Consider that you are an old man, and do not let this noble part of you languish in slavery any longer. Let it not be overborne with selfish passions; let it not quarrel with fate, or be uneasy at the present, or afraid of the future. Providence shines clearly through the work of the gods. Let these reflections satisfy you, and make them your rule to live by. As for books, cease to be eager for them, that you may die in good humour, heartily thanking the gods for what you have had.
Remember that you are a man and a Roman, and let your actions be done with dignity, gravity, humanity, freedom and justice; let every action be done as though it were your last. Have neither insincerity nor self-love. Man has to gain but few points in order to live a happy and godlike life. And what, after all, is there to be afraid of in death? If the gods exist, you can suffer no harm; and if they do not exist, or take no care of us mortals, a world without gods or Providence is not worth a man's while to live in. But the being of thegods, and their concern in human affairs, is beyond dispute; and they have put it in every man's power not to fall into any calamity properly so called. Living and dying, honour and infamy, pleasure and pain, riches and poverty--all these are common to the virtuous and the depraved, and are therefore intrinsically neither good nor evil. We live but for a moment; our being is in a perpetual flux, our faculties are dim, our bodies tend ever to corruption; the soul is an eddy, fortune is not to be guessed at, and posthumous fame is oblivion. To what, then, may we trust? Why, to nothing but philosophy. This is, to keep the interior divinity from injury and disgrace, and superior to pleasure and pain, and to acquiesce in one's appointed lot.
Book III
Observe that the least things and effects in Nature are not without charm and beauty, as the little cracks in the crust of a loaf, though not intended by the baker, are agreeable and invite the appetite. Thus figs, when they are ripest, open and gape; and olives, when they are near decaying, are peculiarly attractive. The bending of an ear of corn, the frown of a lion, the foam of a boar, and many other like things, if you take them singly, are far from beautiful; but seen in their natural relations are characteristic and effective. So if a man have but inclination and thought to examine the product of the universe, he will find that the most unpromising appearances have their own appropriate charm.
Do not spend your thoughts upon other people, nor pry into the talk, fancies and projects of another, nor guess at what he is about, or why he is doing it. Think upon nothing but what you could willingly tell about, so that if your soul were laid open there would appear nothing but what was sincere, good-natured, and public-spirited.A man thus qualified is a sort of priest and minister of the gods, and makes a right use of the divinity within him. Be cheerful; depend not at all on foreign supports, nor beg your happiness of another; don't throw away your legs to stand upon crutches.
If, in the whole compass of human life, you find anything preferable to justice and truth, temperance and fortitude, or to a mind self-satisfied with its own rational conduct and entirely resigned to fate, then turn to it as to your supreme happiness. But if there be nothing more valuable than the divinity within you, if all things are trifles in comparison with this, then don't divide your allegiance. Let your choice run all one way, and be resolute for that which is best. As for other speculations, throw them once for all out of your hand.
Book IV
It is the custom of people to go to unfrequented places and to the seashore and to the hills for retirement; and you yourself have often wished this solitude. But, after all, this is only a vulgar fancy, for it is in your power to withdraw into yourself whenever you have a mind to it. One's own heart is a place the most free from crowd and noise in the world if only one's thoughts are serene and the mind well ordered. Make, therefore, frequent use of this retirement, therein to refresh your virtue. And to this end be always provided with a few short, uncontested notions, to keep your understanding true. Do not forget to retire to this solitude of yours; let there be no straining or struggling in the matter, but move at ease.
If understanding be common to us all, then reason, its cause, must be common, too. And so also must the reason which governs conduct by commands and prohibitions be common to us all. Mankind is thereforeunder one common law, and so are fellow-citizens; and the whole world is but one commonwealth, for there is no other society in which mankind can be incorporated.
