Since it is possible that thou mayest depart from life this very moment, regulate every act and thought accordingly. But to go away from among men, if there are gods, is not a thing to be afraid of, for the gods will not involve thee in evil; but if indeed they do not exist, or if they have no concern about human affairs, what is it to me to live in a universe devoid of gods or devoid of Providence? But in truth they do exist, and they do care for human things, and they have put all the means in man's power to enable him not to fall into real evils. And as to the rest, if there was anything evil, they would have provided for this also, that it should be altogether in a man's power not to fall into it. Now that which does not make a man worse, how can it make a man's life worse? But neither through ignorance, nor having the knowledge, but not the power to guard against or correct these things, is it possible that the nature of the universe has overlooked them; nor is it possible that it has made so great a mistake, either through want of power or want of skill, that good and evil should happen indiscriminately to the good and the bad. But death certainly, and life, honour and dishonour, pain and pleasure, all these things equally happen to good men and bad, being things which make us neither better nor worse. Therefore they are neither good nor evil.
Of human life the time is a point, and the substance is in a flux, and the perception dull, and the composition of the whole body subject to putrefaction, and the soul a whirl, and fortune hard to divine, and fame a thing devoid of judgement. And, to say all in a word, everything which belongs to the body is a stream, and what belongs to the soul is a dream and vapour, and life is a warfare and a stranger's sojourn, and after-fame is oblivion. What then is that which is able to conduct a man? One thing and only one, philosophy. But this consists in keeping the daemon within a man free from violence and unharmed, superior to pains and pleasures, doing nothing without purpose, nor yet falsely and with hypocrisy, not feeling the need of another man's doing or not doing anything; and besides, accepting all that happens, and all that is allotted, as coming from thence, wherever it is, from whence he himself came; and, finally, waiting for death with a cheerful mind, as being nothing else than a dissolution of the elements of which every living being is compounded. But if there is no harm to the elements themselves in each continually changing into another, why should a man have any apprehension about the change and dissolution of all the elements? For it is according to nature, and nothing is evil which is according to nature.
