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 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， 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.
4.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， we are members of some political community； if this is so， the world is in a manner a state. For of what other common political community will any one say that the whole human race are members？ And from thence， from this common political community comes also our very intellectual faculty and reasoning faculty and our capacity for law； or whence do they come？ For as my earthly part is a portion given to me from certain earth， and that which is watery from another element， and that which is hot and fiery from some peculiar source （for nothing comes out of that which is nothing， as nothing also returns to non-existence）， so also the intellectual part comes from some source.
5.Death is such as generation is， a mystery of nature； a composition out of the same elements， and a decomposition into the same； and altogether not a thing of which any man should be ashamed， for it is not contrary to the nature of a reasonable animal， and not contrary to the reason of our constitution.
6.It is natural that these things should be done by such persons， it is a matter of necessity； and if a man will not have it so， he will not allow the fig-tree to have juice. But by all means bear this in mind， that within a very short time both thou and he will be dead； and soon not even your names will be left behind.
7.Take away thy opinion， and then there is taken away the complaint， "I have been harmed." Take away the complaint， "I have been harmed，" and the harm is taken away.
8.That which does not make a man worse than he was， also does not make his life worse， nor does it harm him either from without or from within.
9.The nature of that which is universally useful has been compelled to do this.
10.Consider that everything which happens， happens justly， and if thou observest carefully， thou wilt find it to be so. I do not say only with respect to the continuity of the series of things， but with respect to what is just， and as if it were done by one who assigns to each thing its value. Observe then as thou hast begun； and whatever thou doest， do it in conjunction with this， the being good， and in the sense in which a man is properly understood to be good. Keep to this in every action.
11.Do not have such an opinion of things as he has who does thee wrong， or such as he wishes thee to have， but look at them as they are in truth.
12.A man should always have these two rules in readiness； the one， to do only whatever the reason of the ruling and legislating faculty may suggest for the use of men； the other， to change thy opinion， if there is any one at hand who sets thee right and moves thee from any opinion. But this change of opinion must proceed only from a certain persuasion， as of what is just or of common advantage， and the like， not because it appears pleasant or brings reputation.
