Lit Genius
Principal Doctrines by Epicurus
I. That which is blessed and immortal is not troubled itself, nor does it cause trouble to another. As a result, it is not affected by anger or favor, for these belong to weakness.

II. Death is nothing to us; for what has been dissolved has no sensation, and what has no sensation is nothing to us.

III. The removal of all that causes pain marks the boundary of pleasure. Wherever pleasure is present and as long as it continues, there is neither suffering nor grieving nor both together.

IV. Continuous bodily suffering does not last long. Intense pain is very brief, and even pain that barely outweighs physical pleasure does not last many days. Long illnesses permit physical pleasures that are greater than the pain.

V. It is impossible to live pleasantly without living prudently, well, and justly, (and to live prudently, well, and justly) without living pleasantly. Even though a man live well and justly, it is not possible for him to live pleasantly if he lacks that from which stems the prudent life.

VI. Any device whatever by which one frees himself from the fear of others is a natural good.

VII. Some, thinking thus to make themselves safe from men, wished to become famous and renowned. They won a natural good if they made their lives secure; but if their lives were not secure, they did not have that for which, following the rule of nature, they first sought.

VIII. No pleasure is evil in itself; but the means by which certain pleasures are gained bring pains many times greater than the pleasures.

IX. If every pleasure were cumulative, and if this were the case both in time and in regard to the whole or the most important parts of our nature, then pleasures would not differ from each other.

X. If the things that produce the pleasures of the Dissolute were able to drive away from their minds their fears about what is above them and about death and pain, and to teach them the limit of desires, we would have no reason to find fault with the dissolute; for they would fill themselves with pleasure from every source and would be free from pain and sorrow, which are evil.

XI. If our dread of the phenomena above us, our fear lest death concern us, and our inability to discern the limits of pains and desires were not vexatious to us, we would have no need of the natural sciences.

XII. It is not possible for one to rid himself of his fears about the most important things if he does not understand the nature of the universe but dreads some of the things he has learned in the myths. Therefore, it is not possible to gain unmixed happiness without natural science.

XIII. It is of no avail to prepare security against other men while things above us and beneath the earth and in the whole infinite universe in general are still dreaded.
XIV. When reasonable security from men has been attained, then the security that comes from peace of mind and withdrawal from the crowd is present, sufficient in strength and most unmixed in well-being.

XV. Natural wealth is limited and easily obtained; the wealth defined by vain fancies is always beyond reach.

XVI. Fortune seldom troubles the wise man. Reason has controlled his greatest and most important affairs, controls them throughout his life, and will continue to control them.

XVII. The just man is least disturbed; the unjust man is filled with the greatest turmoil.

XVIII. When once the pain caused by need has been removed, bodily pleasure will not be increased in amount but only varied in quality. The mind attains its utmost pleasure in reflecting on the very things that used to cause the greatest mental fears and on things like them.

XIX. Time that is unlimited and time that is limited afford equal pleasure if one measures pleasure's extent by reason.

XX. The flesh believes that pleasure is limitless and that it requires unlimited time; but the mind, understanding the end and limit of the flesh and ridding itself of fears of the future, secures a complete life and has no longer any need for unlimited time. It does not, however, avoid pleasure; and when circumstances bring on the end of life, it does not depart as if it still lacked any portion of the good life.

XXI. The man who understands the limits of living knows that it is easy to obtain that which removes the pain caused by want and that which perfects the whole life.Therefore, he has no need of things that involve struggle.

XXII. It is necessary to take into account the real purpose of knowledge and all the evidence of that clear perception to which we refer our opinions. If we do not, all will be full of bad judgment and confusion.

XXIII. If you struggle against all your sensations, you will have no standard of comparison by which to measure even the sensations you judge false.

XXIV. If you reject any sensation, and if you fail to distinguish between conjecture based upon that which awaits confirmation and evidence given by the senses, by the feelings, and by the mental examinations of confirmed concepts you will confuse the other sensations with unfounded conjecture and thus destroy the whole basis for judgment. If among all opinions you accept as equally valid both those that await confirmation and those that have been confirmed, you will not free yourself from error, since you will have preserved judgment of what is true and what is not true.

XXV. If you do not at all times refer each of your actions to the natural end, but fall short of this and turn aside to something else in choosing and avoiding, your deeds will not agree with your words.

XXVI. Those desires that do not bring pain if they are not satisfied are not necessary; and they are easily thrust aside whenever to satisfy them appears difficult or likely to cause injury.
XXVII. Of the things that wisdom prepares for insuring lifelong happiness, by far the greatest is the possession of friends.

XXVIII. The same wisdom that permits us to be confident that no evil is eternal or even of long duration also recognizes that in our limited state the security that can be most perfectly gained is that of friendship.

XXIX. Of the desires, some are natural (and necessary; some are natural) but not necessary; and others are neither natural nor necessary but arise from empty opinion.

XXX. Among the bodily desires, those rest on empty opinion that are eagerly pursued although if unsatisfied they bring no pain.That they are not got rid of is because of man's empty opinion, not because of their own nature.

XXXI. Natural justice is a compact resulting from expediency by which men seek to prevent one man from injuring others and to protect him from being injured by them.

XXXII. There is no such thing as justice or injustice among those beasts that cannot make agreements not to injure or be injured.This is also true of those tribes that are unable or unwilling to make agreements not to injure or be injured.

XXXIII. There is no such thing as justice in the abstract; it is merely a compact between men in their various relations with each other, in whatever circumstances they may be, that they will neither injure nor be injured.

XXXIV. Injustice is not evil in itself, but only in the fear and apprehension that one will not escape those who have been set up to punish the offense.

XXXV. If a man has secretly violated any of the terms of the mutual compact not to injure or be injured, he cannot feel confident that he will be undetected in the future even if he has escaped ten thousand times in the past; for until his death it will remain uncertain whether he will escape.

XXXVI. In general, justice is the same for all, a thing found useful by men in their relations with each other; but it does not follow that it is the same for all in each individual place and circumstance.

XXXVII. Among the things commonly held just, that which has proved itself useful in men's mutual relationships has the stamp of justice whether or not it be the same for all; if anyone makes a law and it does not prove useful in men's relationships with each other, it is no longer just in its essence. If, however, the law's usefulness in the matter of justice should change and it should meet men's expectations only for a short time, nonetheless during that short time it was just in the eyes of those who look simply at facts and do not confuse themselves with empty words.

XXXVIII. If, although no new circumstances have arisen, those things that were commonly held just in these matters did not in their actual effects correspond with that conception, they were not just. Whenever, as a result of new circumstances, the same things that had been regarded as just were no longer useful, they were just at the time when they were useful for the relations of citizens to each other; but afterwards, when they were no longer useful, they were no longer just.

XXXIX. He who has best controlled his lack of confidence in the face of external forces has, as far as possible, treated these externals as akin to himself or, when that was impossible, at least as not alien. Where he was not able to do even this, he kept to himself and avoided whatever it was best to avoid.
XL. Those who were best able to prepare security for themselves in relation to their neighbors lived most pleasantly with their neighbors since they had the most perfect assurance; and enjoying the most complete intimacy, they did not lament the death of one who died before his time as if it were an occasion for sorrow.
