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 vapor; and life is a warfare, and a stranger's sojourn, and after fame is oblivion. What, then, is that which is able to enrich a man? One thing, and only one—philosophy. But this consists in keeping the guardian spirit within a man free from violence and unharmed, superior to pains and pleasures, doing nothing without a purpose, nor yet falsely, and with hypocrisy ... accepting all that happens and all that is allotted ... and finally waiting for death with a cheerful mind.
If thou findest in human life anything better than justice, truth, temperance, fortitude, and, in a word, than thine own soul's satisfaction in the things which it enables thee to do according to right reason, and in the condition that is assigned to thee without thy own choice; if, I say, thou seest anything better than this, turn to it with all thy soul, and enjoy that which thou hast found to be the best. But ... if thou findest everything else smaller and of less value than this, give place to nothing else.... Simply and freely choose the better, and hold to it.
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 tranquillity—which is nothing else than the good ordering of the mind.
Unhappy am I, because this has happened to me? Not so, but happy am I though this has happened to me, because I continue free from pain; neither crushed by the present nor fearing the future.
Be cheerful, and seek no external help, nor the tranquillity which others give. A man must stand erect, not be kept erect by others.
Be like the promontory against which the waves continually break, but it stands firm and tames the fury of the water around it.
It is not fit that I should give myself pain, for I have never intentionally given pain even to another.
IMMANUEL KANT
The canons of scientific evidence justify us neither in accepting nor rejecting the ideas upon which morality and religion repose. Both parties to the dispute beat the air; they worry their own shadow; for they pass from Nature into the domain of speculation, where their dogmatic grips find nothing to lay hold upon. The shadows which they hew to pieces grow together in a moment like the heroes in Valhalla, to rejoice again in bloodless battles. Metaphysics can no longer claim to be the cornerstone of religion and morality. But if she can not be the Atlas that bears the moral world she can furnish a magic defense. Around the ideas of religion she throws her bulwark of invisibility; and the sword of the skeptic and the battering-ram of the materialist fall harmless on vacuity.
