Epicurus in his letter to Menoeceus: “Become accustomed to the belief that death is nothing to us. For all good and evil consists in sensation, but death is deprivation of sensation. And therefore a right understanding that death is nothing to us makes the mortality of life enjoyable, not because it adds to it an infinite span of time, but because it takes away the craving for immortality.  For there is nothing terrible in life for the man who has truly comprehended that there is nothing terrible in not living. So that the man speaks but idly who says that he fears death not because it will be painful when it comes, but because it is painful in anticipation. For that which gives no trouble when it comes is but an empty pain in anticipation. So death, the most terrifying of ills, is nothing to us, since so long as we exist, death is not with us; but when death comes, then we do not exist. It does not then concern either the living or the dead, since for the former it is not, and the latter are no more.  But the many at one moment shun death as the greatest of evils, at another (yearn for it) as a respite from the (evils) in life. (But the wise man neither seeks to escape life) nor fears the cessation of life, for neither does life offend him nor does the absence of life seem to be any evil. And just as with food he does not seek simply the larger share and nothing else, but rather the most pleasant, so he seeks to enjoy not the longest period of time, but the most pleasant. And he who counsels the young man to live well, but the old man to make a good end, is foolish, not merely because of the desirability of life, but also because it is the same training which teaches to live well and to die well. Yet much worse still is the man who says it is good not to be born but ‘once born make haste to pass the gates of Death’  For if he says this from conviction why does he not pass away out of life? For it is open to him to do so, if he had firmly made up his mind to this. But if he speaks in jest, his words are idle among men who cannot receive them.
PD01. The blessed and immortal nature knows no trouble itself, nor causes trouble to any other, so that it is never constrained by anger or favor. For all such things exist only in the weak.
Go through the examples asked of Nature at the end of Book 2, such as thinking about the time before you were born. Were you in pain then?
Torquatus: Again, it is a fine saying of Epicurus that … “no greater pleasure could be derived from a life of infinite duration than is actually afforded by this existence which we know to be finite.”
“Torquatus” from Cicero’s On Ends; 'XIII. Those who place the Chief Good in virtue alone are beguiled by the glamour of a name, and do not understand the true demands of nature. If they will consent to listen to Epicurus, they will be delivered from the grossest error. Your school dilates on the transcendent beauty of the virtues; but were they not productive of pleasure, who would deem them either praiseworthy or desirable? We esteem the art of medicine not for its interest as a science, but for its conduciveness to health; the art of navigation is commended for its practical and not its scientific value, because it conveys the rules for sailing a ship with success. So also Wisdom, which must be considered as the art of living, if it effected no result would not be desired; but as it is, it is desired, because it is the artificer that procures and produces pleasure.” … “If then even the glory of the Virtues, on which all the other philosophers love to expatiate so eloquently, has in the last resort no meaning unless it be based on pleasure, whereas pleasure is the only thing that is intrinsically attractive and alluring, it cannot be doubted that pleasure is the one supreme and final Good and that a life of happiness is nothing else than a life of pleasure.
Diogenes of Oinoanda, from his Inscription, Fragment 32: ” If, gentlemen, the point at issue between these people and us involved inquiry into «what is the means of happiness?» and they wanted to say «the virtues» (which would actually be true), it would be unnecessary to take any other step than to agree with them about this, without more ado. But since, as I say, the issue is not «what is the means of happiness?» but «what is happiness and what is the ultimate goal of our nature?», I say both now and always, shouting out loudly to all Greeks and non-Greeks, that pleasure is the end of the best mode of life, while the virtues, which are inopportunely messed about by these people (being transferred from the place of the means to that of the end), are in no way an end, but the means to the end. Let us therefore now state that this is true, making it our starting-point.”
Epicurus in his letter to Menoeceus: “We must consider that of desires some are natural, others vain, and of the natural some are necessary and others merely natural; and of the necessary some are necessary for happiness, others for the repose of the body, and others for very life.  The right understanding of these facts enables us to refer all choice and avoidance to the health of the body and (the soul’s) freedom from disturbance, since this is the aim of the life of blessedness. …
Epicurus in his letter to Menoeceus: “And again independence of desire we think a great good — not that we may at all times enjoy but a few things, but that, if we do not possess many, we may enjoy the few in the genuine persuasion that those have the sweetest pleasure in luxury who least need it, and that all that is natural is easy to be obtained, but that which is superfluous is hard. And so plain savours bring us a pleasure equal to a luxurious diet, when all the pain due to want is removed; and bread and water produce the highest pleasure, when one who needs them puts them to his lips.  To grow accustomed therefore to simple and not luxurious diet gives us health to the full, and makes a man alert for the needful employments of life, and when after long intervals we approach luxuries disposes us better towards them, and fits us to be fearless of fortune. When, therefore, we maintain that pleasure is the end, we do not mean the pleasures of profligates and those that consist in sensuality, as is supposed by some who are either ignorant or disagree with us or do not understand, but freedom from pain in the body and from trouble in the mind.  For it is not continuous drinkings and revelings, nor the satisfaction of lusts, nor the enjoyment of fish and other luxuries of the wealthy table, which produce a pleasant life, but sober reasoning, searching out the motives for all choice and avoidance, and banishing mere opinions, to which are due the greatest disturbance of the spirit. ==== Identify at the very beginning of your study that you are not seeking knowledge for the sake of knowledge, but you are working so that you will live well. ==== 1. Epicurus from his letter to Pythocles: “First of all then we must not suppose that any other object is to be gained from the knowledge of the phenomena of the sky, whether they are dealt with in connection with other doctrines or independently, than peace of mind and a sure confidence, just as in all other branches of study.  We must not try to force an impossible explanation, nor employ a method of inquiry like our reasoning either about the modes of life or with respect to the solution of other physical problems: witness such propositions as that ‘the universe consists of bodies and the intangible,’ or that ‘the elements are indivisible,’ and all such statements in circumstances where there is only one explanation which harmonizes with phenomena. For this is not so with the things above us: they admit of more than one cause of coming into being and more than one account of their nature which harmonizes with our sensations.  For we must not conduct scientific investigation by means of empty assumptions and arbitrary principles, but follow the lead of phenomena: for our life has not now any place for irrational belief and groundless imaginings, but we must live free from trouble. Now all goes on without disturbance as far as regards each of those things which may be explained in several ways so as to harmonize with what we perceive, when one admits, as we are bound to do, probable theories about them. But when one accepts one theory and rejects another which harmonizes as well with the phenomenon, it is obvious that he altogether leaves the path of scientific inquiry and has recourse to myth. Now we can obtain indications of what happens above from some of the phenomena on earth: for we can observe how they come to pass, though we cannot observe the phenomena in the sky: for they may be produced in several ways.  Yet we must never desert the appearance of each of these phenomena, and further, as regards what is associated with it, must distinguish those things whose production in several ways is not contradicted by phenomena on earth.”
Torquatus from Cicero’s On Ends: “There remains a topic that is pre-eminently germane to this discussion, I mean the subject of Friendship. Your school maintains that if pleasure be the Chief Good, friendship will cease to exist. Now Epicurus’s pronouncement about friendship is that of all the means to happiness that wisdom has devised, none is greater, none more fruitful, none more delightful than this. Nor did he only commend this doctrine by his eloquence, but far more by the example of his life and conduct. How great a thing such friendship is, is shown by the mythical stories of antiquity. Review the legends from the remotest ages, and, copious and varied as they are, you will barely find in them three pairs of friends, beginning with Theseus and ending with Orestes. Yet Epicurus in a single house and that a small one maintained a whole company of friends, united by the closest sympathy and affection; and this still goes on in the Epicurean school. But to return to our subject, for there is no need of personal instances: I notice that the topic of friendship has been treated by Epicureans in three ways: (1) Some have denied that pleasures affecting our friends are in themselves to be desired by us in the same degree as we desire our own pleasures. This doctrine is thought by some critics to undermine the foundations of friendship; however, its supporters defend their position, and in my opinion have no difficulty in making good their ground. They argue that friendship can no more be sundered from pleasure than can the virtues, which we have discussed already. A solitary, friendless life must be beset by secret dangers and alarms. Hence reason itself advises the acquisition of friends; their possession gives confidence, and a firmly rooted hope of winning pleasure. And just as hatred, jealousy, and contempt are hindrances to pleasure, so friendship is the most trustworthy preserver and also creator of pleasure alike for our friends and for ourselves. It affords us enjoyment in the present, and it inspires us with hopes for the near and distant future. Thus it is not possible to secure uninterrupted gratification in life without friendship, nor yet to preserve friendship itself unless we love our friends as much as ourselves. Hence this unselfishness does occur in friendship, while also friendship is closely linked with pleasure. For we rejoice in our friends’ joy as much as in our own, and are equally pained by their sorrows. Therefore the Wise Man will feel exactly the same towards his friend as he does towards himself, and will exert himself as much for his friend’s pleasure as he would for his own. All that has been said about the essential connection of the virtues with pleasure must be repeated about friendship. Epicurus well said (I give almost his exact words): “The same creed that has given us courage to overcome all fear of everlasting or long-enduring evil hereafter, has discerned that friendship is our strongest safeguard in this present term of life.” (2) Other Epicureans though by no means lacking in insight are a little less courageous in defying the opprobrious criticisms of the Academy. They fear that if we hold friendship to be desirable only for the pleasure that it affords to ourselves, it will be thought that it is crippled altogether. They therefore say that the first advances and overtures, and the original inclination to form an attachment, are prompted by the desire for pleasure, but that when the progress of intercourse has led to intimacy, the relationship blossoms into an affection strong enough to make us love our friends for their own sake, even though no practical advantage accrues from their friendship, Does not familiarity endear to us localities, temples, cities, gymnasia, and playing-grounds, horses and hounds, gladiatorial shows and fights with wild beasts, then how much more natural and reasonable that this should be able to happen in our intercourse with our fellow-men! (3) The third view is that wise men have made a sort of compact to love their friends no less than themselves. We can understand the possibility of this, and we often see it happen. Clearly no more effective means to happiness could be found than such an alliance. All these considerations go to prove not only that the theory of friendship is not embarrassed by the identification of the Chief Good with pleasure, but also that without this no foundation for friendship whatsoever can be found.
“Torquatus” in Cicero’s “On Ends’: “XII. The truth of the position that pleasure is the ultimate good will most readily appear from the following illustration. Let us imagine a man living in the continuous enjoyment of numerous and vivid pleasures alike of body and of mind, undisturbed either by the presence or by the prospect of pain: what possible state of existence could we describe as being more excellent or more desirable? One so situated must possess in the first place a strength of mind that is proof against all fear of death or of pain; he will know that death means complete unconsciousness, and that pain is generally light if long and short if strong, so that its intensity is compensated by brief duration and its continuance by diminishing severity. Let such a man moreover have no dread of any supernatural power; let him never suffer the pleasures of the past to fade away, but constantly renew their enjoyment in recollection, and his lot will be one which will not admit of further improvement. Suppose on the other hand a person crushed beneath the heaviest load of mental and of bodily anguish to which humanity is liable. Grant him no hope of ultimate relief in view also give him no pleasure either present or in prospect. Can one describe or imagine a more pitiable state? If then a life full of pain is the thing most to be avoided, it follows that to live in pain is the highest evil; and this position implies that a life of pleasure is the ultimate good. In fact the mind possesses nothing in itself upon which it can rest as final. Every fear, every sorrow can be traced back to pain; there is no other thing besides pain which is of its own nature capable of causing either anxiety or distress. Pleasure and pain moreover supply the motives of desire and of avoidance, and the springs of conduct generally. This being so, it clearly follows that actions are right and praiseworthy only as being a means to the attainment of a life of pleasure. But that which is not itself a means to anything else, but to which all else is a means, is what the Greeks term the Telos, the highest, ultimate or final Good. It must therefore be admitted that the Chief Good is to live agreeably.”
Epicurus in his letter to Menoeceus: “Of all this the beginning and the greatest good is prudence. Wherefore prudence is a more precious thing even than philosophy: for from prudence are sprung all the other virtues, and it teaches us that it is not possible to live pleasantly without living prudently and honorably and justly, (nor, again, to live a life of prudence, honor, and justice) without living pleasantly. For the virtues are by nature bound up with the pleasant life, and the pleasant life is inseparable from them.  For indeed who, think you, is a better man than he who holds reverent opinions concerning the gods, and is at all times free from fear of death, and has reasoned out the end ordained by nature? He understands that the limit of good things is easy to fulfill and easy to attain, whereas the course of ills is either short in time or slight in pain; he laughs at (destiny), whom some have introduced as the mistress of all things. (He thinks that with us lies the chief power in determining events, some of which happen by necessity) and some by chance, and some are within our control; for while necessity cannot be called to account, he sees that chance is inconstant, but that which is in our control is subject to no master, and to it are naturally attached praise and blame.  For, indeed, it were better to follow the myths about the gods than to become a slave to the destiny of the natural philosophers: for the former suggests a hope of placating the gods by worship, whereas the latter involves a necessity which knows no placation. As to chance, he does not regard it as a god as most men do (for in a god’s acts there is no disorder), nor as an uncertain cause (of all things) for he does not believe that good and evil are given by chance to man for the framing of a blessed life, but that opportunities for great good and great evil are afforded by it.
Torquatus from Cicero’s On Ends: ”(2) Again, we aver that mental pleasures and pains arise out of bodily ones (and therefore I allow your contention that any Epicureans who think otherwise put themselves out of court; and I am aware that many do, though not those who can speak with authority); but although men do experience mental pleasure that is agreeable and mental pain that is annoying, yet both of these we assert arise out of and are based upon bodily sensations. Yet we maintain that this does not preclude mental pleasures and pains from being much more intense than those of the body; since the body can feel only what is present to it at the moment, whereas the mind is also cognizant of the past and of the future. For granting that pain of body is equally painful, yet our sensation of pain can be enormously increased by the belief that some evil of unlimited magnitude and duration threatens to befall us hereafter. And the same consideration may be transferred to pleasure: a pleasure is greater if not accompanied by any apprehension of evil. This therefore clearly appears, that intense mental pleasure or distress contributes more to our happiness or misery than a bodily pleasure or pain of equal duration. (4) But we do not agree that when pleasure is withdrawn uneasiness at once ensues, unless the pleasure happens to have been replaced by a pain: while on the other hand one is glad to lose a pain even though no active sensation of pleasure comes in its place: a fact that serves to show how great a pleasure is the mere absence of pain. (5) But just as we are elated by the anticipation of good things, so we are delighted by their recollection. Fools are tormented by the memory of former evils; wise men have the delight of renewing in grateful remembrance the blessings of the past. We have the power both to obliterate our misfortunes in an almost perpetual forgetfulness and to summon up pleasant and agreeable memories of our successes. But when we fix our mental vision closely on the events of the past, then sorrow or gladness ensues according as these were evil or good.
Torquatus from Cicero’s On Ends: “Here is indeed a royal road to happiness—open, simple, and direct! For clearly man can have no greater good than complete freedom from pain and sorrow coupled with the enjoyment of the highest bodily and mental pleasures. Notice then how the theory embraces every possible enhancement of life, every aid to the attainment of that Chief Good which is our object. Epicurus, the man whom you denounce as a voluptuary, cries aloud that no one can live pleasantly without living wisely, honorably, and justly, and no one wisely, honorably, and justly without living pleasantly. For a city rent by faction cannot prosper, nor a house whose masters are at strife; much less then can a mind divided against itself and filled with inward discord taste any particle of pure and liberal pleasure. But one who is perpetually swayed by conflicting and incompatible counsels and desires can know no peace or calm. Why, if the pleasantness of life is diminished by the more serious bodily diseases, how much more must it be diminished by the diseases of the mind! But extravagant and imaginary desires, for riches, fame, power, and also for licentious pleasures, are nothing but mental diseases. Then, too, there are grief, trouble and sorrow, which gnaw the heart and consume it with anxiety, if men fail to realize that the mind need feel no pain unconnected with some pain of body, present or to come. Yet there is no foolish man but is afflicted by some one of these diseases; therefore there is no foolish man that is not unhappy. Moreover, there is death, the stone of Tantalus ever hanging over men’s heads; and superstition, that poisons and destroys all peace of mind. Besides, they do not recollect their past nor enjoy their present blessings; they merely look forward to those of the future, and as these are of necessity uncertain, they are consumed with agony and terror; and the climax of their torment is when they perceive too late that all their dreams of wealth or station, power or fame, have come to nothing. For they never attain any of the pleasures, the hope of which inspired them to undergo all their arduous toils. Or look again at others, petty, narrow-minded men, or confirmed pessimists, or spiteful, envious, ill-tempered creatures, unsociable, abusive, brutal; others again enslaved to the follies of love, impudent or reckless, wanton, headstrong and yet irresolute, always changing their minds. Such failings render their lives one unbroken round of misery. The conclusion is that no foolish man can be happy, nor any wise man fail to be happy. This is a truth that we establish far more conclusively than do the Stoics. For they maintain that nothing is good save that vague phantom which they entitle Moral Worth, a title more splendid than substantial; and say that Virtue resting on this Moral Worth has no need of pleasure, but is herself her own sufficient happiness. At the same time this Stoic doctrine can be stated in a form which we do not object to, and indeed ourselves endorse. For Epicurus thus presents his Wise Man who is always happy: his desires are kept within bounds; death he disregards; he has a true conception, untainted by fear, of the Divine nature; he does not hesitate to depart from life, if that would better his condition. Thus equipped he enjoys perpetual pleasure, for there is no moment when the pleasures he experiences do not outbalance the pains; since he remembers the past with gratitude, grasps the present with a full realization of its pleasantness, and does not rely upon the future; he looks forward to it, but finds his true enjoyment in the present. Also he is entirely free from the vices that I instanced a few moments ago, and he derives no inconsiderable pleasure from comparing his own existence with the life of the foolish.
