Body, soul, intelligence: to the body belong sensations, to the soul appetites, to the intelligence principles. To receive the impressions of forms by means of appearances belongs even to animals; to be pulled by the strings36 of desire belongs both to wild beasts and to men who have made themselves into women, and to a Phalaris and a Nero: and to have the intelligence that guides to the things which appear suitable belongs also to those who do not believe in the gods, and who betray their country, and do their impure deeds when they have shut the doors. If then everything else is common to all that I have mentioned, there remains that which is peculiar to the good man, to be pleased and content with what happens, and with the thread which is spun for him; and not to defile the divinity which is planted in his breast, nor disturb it by a crowd of images, but to preserve it tranquil, following it obediently as a god, neither saying anything contrary to the truth, nor doing anything contrary to justice. And if all men refuse to believe that he lives a simple, modest, and contented life, he is neither angry with any of them, nor does he deviate from the way which leads to the end of life, to which a man ought to come pure, tranquil, ready to depart, and without any compulsion perfectly reconciled to his lot.
Book IV
That which rules within, when it is according to nature, is so affected with respect to the events which happen, that it always easily adapts itself to that which is and is presented to it. For it requires no definite material, but it moves towards its purpose,37 under certain conditions however; and it makes a material for itself out of that which opposes it, as fire lays hold of what falls into it, by which a small light would have been extinguished: but when the fire is strong, it soon appropriates to itself the matter which is heaped on it, and consumes it, and rises higher by means of this very material.
Let no act be done without a purpose, nor otherwise than according to the perfect principles of art.
Men seek retreats for themselves, houses in the country, seashores, 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 tranquility; and I affirm that tranquility 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. For with what art thou discontented? With the badness of men? Recall to thy mind this conclusion, that rational animals exist for one another, and that to endure is a part of justice, and that men do wrong involuntarily; and consider how many already, after mutual enmity, suspicion, hatred, and fighting, have been stretched dead, reduced to ashes; and be quiet at last.—But perhaps thou art dissatisfied with that which is assigned to thee out of the universe.—Recall to thy recollection this alternative; either there is providence or atoms, fortuitous concurrence of things; or remember the arguments by which it has been proved that the world is a kind of political community, and be quiet at last.—But perhaps corporeal things will still fasten upon thee.—Consider then further that the mind mingles not with the breath, whether moving gently or violently, when it has once drawn itself apart and discovered its own power, and think also of all that thou hast heard and assented to about pain and pleasure, and be quiet at last.—But perhaps the desire of the thing called fame will torment thee.—See how soon everything is forgotten, and look at the chaos of infinite time on each side of the present, and the emptiness of applause, and the changeableness and want of judgement in those who pretend to give praise, and the narrowness of the space within which it is circumscribed, and be quiet at last. For the whole earth is a point, and how small a nook in it is this thy dwelling, and how few are there in it, and what kind of people are they who will praise thee.
This then remains: Remember to retire into this little territory of thy own,38 and above all do not distract or strain thyself, but be free, and look at things as a man, as a human being, as a citizen, as a mortal. But among the things readiest to thy hand to which thou shalt turn, let there be these, which are two. One is that things do not touch the soul, for they are external and remain immovable; but our perturbations come only from the opinion which is within. The other is that all these things, which thou seest, change immediately and will no longer be; and constantly bear in mind how many of these changes thou hast already witnessed. The universe is transformation: life is opinion.
If our intellectual part is common, the reason also, in respect of which we are rational beings, is common: if this is so, common also is the reason which commands us what to do, and what not to do; if this is so, there is a common law also; if this is so, we are fellow-citizens; if this is so,
