Marcus Aurelius
Meditations 4.3
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. 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 judgment 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, 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.
Marcus Aurelius, Meditations 4.3, translated by George Long
Men seek out retreats for themselves in the country, by the seaside, on the mountains, and thou too art wont to long intensely for such things. But all this is unphilosophical to the last degree, when thou canst at a moment's notice retire into thyself. For nowhere can a man find a retreat more full of peace or more free from care than his own soul—above all if he have that within him, a steadfast look at which and he is at once in all good ease, and by good ease I mean nothing other than good order. Make use then of this retirement continually and regenerate thyself. Let thy axioms be short and elemental, such as, when set before thee, will at once rid thee of all trouble, and send thee away with no discontent at those things to which thou art returning.
For with what art thou discontented? The wickedness of men? Take this conclusion to heart, that rational creatures have been made for one another; that forbearance is part of justice; that wrong-doing is involuntary; and think how many ere now, after passing their lives in implacable enmity, suspicion, hatred, and at daggers drawn with one another, have been laid out and burnt to ashes—think of this, I say, and at last stay thy fretting. But art thou discontented with thy share in the whole? Recall the alternative: Either Providence or Atoms! and the abundant proofs there are that the Universe is as it were a state. But is it the affections of the body that shall still lay hold on thee? Bethink thee that the Intelligence, when it has once abstracted itself and learnt its own power, has nothing to do with the motions smooth or rough of the vital breath. Bethink thee too of all that thou hast heard and subscribed to about pleasure and pain.
But will that paltry thing, Fame, pluck thee aside? Look at the swift approach of complete forgetfulness, and the void of infinite time on this side of us and on that, and the empty echo of acclamation, and the fickleness and uncritical judgment of those who claim to speak well of us, and the narrowness of the arena to which all this is confined. For the whole earth is but a point, and how tiny a corner of it is this the place of our sojourning! and how many therein and of what sort are the men who shall praise thee!
From now therefore bethink thee of the retreat into this little plot that is thyself. Above all distract not thyself, be not too eager, but be thine own master, and look upon life as a man, as a human being, as a citizen, as a mortal creature. But among the principles readiest to thine hand, upon which thou shalt pore, let there be these two. One, that objective things do not lay hold of the soul, but stand quiescent without; while disturbances are but the outcome of that opinion which is within us. A second, that all this visible world changes in a moment, and will be no more; and continually bethink thee to the changes of how many things thou hast already been a witness. 'The Universe—mutation: Life—opinion.'
