• Death is the release from all pain and complete cessation, beyond which our suffering will not extend. It will return us to that condition of tranquility, which we had enjoyed before we were born. Should anyone mourn the deceased, then he must also mourn the unborn. Death is neither good nor evil, for good or evil can only be something that actually exists. However, whatever is of itself nothing and which transforms everything else into nothing will not all be able to put us at the mercy of Fate.
  • As quoted by Gunther von Hagens in his Body Worlds exhibit.

• We are mad, not only individually, but nationally. We check manslaughter and isolated murders; but what of war and the much-vaunted crime of slaughtering whole peoples? There are no limits to our greed, none to our cruelty. And as long as such crimes are committed by stealth and by individuals, they are less harmful and less portentous; but cruelties are practised in accordance with acts of senate and popular assembly, and the public is bidden to do that which is forbidden to the individual. Deeds that would be punished by loss of life when committed in secret, are praised by us because uniformed generals have carried them out. Man, naturally the gentlest class of being, is not ashamed to revel in the blood of others, to wage war, and to entrust the waging of war to his sons, when even dumb beasts and wild beasts keep the peace with one another. Against this overmastering and widespread madness philosophy has become a matter of greater effort, and has taken on strength in proportion to the strength which is gained by the opposition forces.

On Tranquility of the Mind

A letter to Serenus as translated in Tranquillity of Mind and Providence (1900) by William Bell Langsdorf

• We are all chained to fortune: the chain of one is made of gold, and wide, while that of another is short and rusty. But what difference does it make? The same prison surrounds all of us, and even those who have bound others are bound themselves; unless perchance you think that a chain on the left side is lighter. Honors bind one man, wealth another; nobility oppresses some, humility others; some are held in subjection by an external power, while others obey the tyrant within; banishments keep some in one place, the priesthood others. All life is slavery. Therefore each one must accustom himself to his own condition and complain about it as little as possible, and lay hold of whatever good is to be found near him. Nothing is so bitter that a calm mind cannot find comfort in it. Small tablets, because of the writer's skill, have often served for many purposes, and a clever arrangement has often made a very narrow piece of land habitable. Apply reason to difficulties; harsh circumstances can be softened, narrow limits can be widened, and burdensome things can be made to press less severely on those who bear them cleverly.

• That man lives badly who does not know how to die well.

• Should I be surprised that dangers which have always surrounded me should at last attack me? A great part of mankind, when about to sail, do not think of a storm. I shall never be ashamed of a reporter of bad news in a good cause.
  • Variant translation: I shall never be ashamed of citing a bad author if the line is good.

• Virtue runs no risk of becoming contemptible by being exposed to view, and it is better to be despised for simplicity than to be tormented by continual hypocrisy.

• Our minds must have relaxation: rested, they will rise up better and keener. Just as we must not force fertile fields (for uninterrupted production will quickly exhaust them), so continual labor will break the power of our minds. They will recover their strength, however, after they have had a little freedom and relaxation.

• Whether we believe the Greek poet, "it is sometimes even pleasant to be mad", or Plato, "he who is master of himself has knocked in vain at the doors of poetry"; or Aristotle, "no great genius was without a mixture of insanity"; the mind cannot express anything lofty and above the ordinary unless inspired. When it despises the common and the customary, and with sacred inspiration rises higher, then at length it sings something grander than that which can come from mortal lips. It cannot attain anything sublime and lofty so long as it is sane: it must depart from the customary, swing itself aloft, take the bit in its teeth, carry away its rider and bear him to a height whither he would have feared to ascend alone.
  • Quotations Seneca makes this passage have been attributed to him, but he states himself to be quoting others, including Aristotle: "There is no great genius without some touch of madness."
