Cicero, In Defense of Publius Sestius, 10.23: “He {Publius Clodius} praised those most who are said to be above all others the teachers and eulogists of pleasure {the Epicureans}. … He added that these same men were quite right in saying that the wise do everything for their own interests; that no sane man should engage in public affairs; that nothing was preferable to a life of tranquility crammed full of pleasures. But those who said that men should aim at an honorable position, should consult the public interest, should think of duty throughout life not of self-interest, should face danger for their country, receive wounds, welcome death – these he called visionaries and madmen.” Note: Here is a link to Perseus where the Latin and translation of this can be compared. The Latin is: “nihil esse praestabilius otiosa vita, plena et conferta voluptatibus.” See also here for word translations.
Plutarch, That Epicurus actually makes a pleasant life impossible, 3, p. 1088C: “Epicurus has imposed a limit on pleasures that applies to all of them alike: the removal of all pain. For he believes that our nature adds to pleasure only up to the point where pain is abolished and does not allow it any further increase in magnitude (although the pleasure, when the state of painlessness is reached, admits of certain unessential variations). But to proceed to this point, accompanied by desire, is our stint of pleasure, and the journey is indeed short and quick. Hence it is that becoming aware of the poverty here they transfer their final good from the body, as from an unproductive piece of land, to the soul, persuaded that there they will find pastures and meadows lush with pleasures.”
Plutarch, That Epicurus actually makes a pleasant life impossible, 7, p. 1091A: Not only is the basis that they assume for the pleasurable life untrustworthy and insecure, it is quite trivial and paltry as well, inasmuch as their “thing delighted” – their good – is an escape from ills, and they say that they can conceive of no other, and indeed that our nature has no place at all in which to put its good except the place left when its evil is expelled. … Epicurus too makes a similar statement to the effect that the good is a thing that arises out of your very escape from evil and from your memory and reflection and gratitude that this has happened to you. His words are these: “That which produces a jubilation unsurpassed is the nature of good, if you apply your mind rightly and then stand firm and do not stroll about {a jibe at the Peripatetics}, prating meaninglessly about the good.”
Athenaeus, Deipnosophists, XII p. 546E: Not only Aristippus and his followers, but also Epicurus and his welcomed kinetic pleasure; I will mention what follows, to avoid speaking of the “storms” {of passion} and the “delicacies” which Epicurus often cites, and the “stimuli” which he mentions in his On the End-Goal. For he says “For I at least do not even know what I should conceive the good to be, if I eliminate the pleasures of taste, and eliminate the pleasures of sex, and eliminate the pleasures of listening, and eliminate the pleasant motions caused in our vision by a visible form.
Cicero, Tusculan Disputations, III.18.41: Why do we shirk the question, Epicurus, and why do we not confess that we mean by pleasure what you habitually say it is, when you have thrown off all sense of shame? Are these your words or not? For instance, in that book which embraces all your teaching (for I shall now play the part of translator, so no one may think I am inventing) you say this: “For my part I find no meaning which I can attach to what is termed good, if I take away from it the pleasures obtained by taste, if I take away the pleasures which come from listening to music, if I take away too the charm derived by the eyes from the sight of figures in movement, or other pleasures by any of the senses in the whole man. Nor indeed is it possible to make such a statement as this – that it is joy of the mind which is alone to be reckoned as a good; for I understand by a mind in a state of joy, that it is so, when it has the hope of all the pleasures I have named – that is to say the hope that nature will be free to enjoy them without any blending of pain.” And this much he says in the words I have quoted, so that anyone you please may realize what Epicurus understands by pleasure.
Cicero, Tusculan Disputations, III.20.46: For he has not only used the term pleasure, but stated clearly what he meant by it. “Taste,” he says, “and embraces and spectacles and music and the shapes of objects fitted to give a pleasant impression to the eyes.”
Cicero, On End-Goals, Good and Bad, II.3.7 (Torquatus to Cicero): “Does not Epicurus recognize pleasure in your sense?” (Cicero): “Not always,” said I, “now and then, I admit, he recognizes it only too fully, for he solemnly avows that he cannot even understand what good there can be or where it can be found, apart form that which is derived from food and drink, the delight of the ears, and the grosser forms of gratification. Do I misrepresent his words?” Ibid., II.7.20: In a number of passages where he is commending that real pleasure which all of us call by the same name, he goes so far as to say that he cannot even imagine any Good that is not connected with pleasure of the kind intended by Aristippus. Such is the language that he uses in the lecture dealing solely with the topic of the Chief Good. II.8.23: Men of taste and refinement, with first-rate chefs… the accompaniment of dramatic performances and their usual sequel – these are pleasures without which Epicurus, as he loudly proclaims, does not know what Good is. II.10.29: But fancy his failing to see how strong a proof it is that the sort of pleasure, without which he declares he has no idea at all what Good means (and he defines it in detail as the pleasure of the palate, of the ears, and subjoins the other kinds of pleasure, which cannot be specified without an apology). I.10.30: the kinetic sort of pleasure … he extols it so much that he tells us he is incapable even of imagining what other good there can be. II.20:64: … Nor did he forgo those other indulgences in the absence of which Epicurus declares that he cannot understand what good is.
Cicero, On End-Goals, Good and Bad: 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.
Plotinus, Dissertations, 30 (Aeneids, II.9), 15: “For there are two schools of thought about attaining the [ethical] end. One which puts forward the pleasure of the body as the end, and another which chooses nobility and virtue … Epicurus, who abolishes providence, exhorts to pursue all that remains: pleasure and its enjoyment.”
Antiochus of Ascalon, by way of Clement of Alexandria, Miscellanies II.21 p. 178.43: “For of those that are ruled by pleasure are the Cyrenaics and Epicurus; for these expressly said that to live pleasantly was the chief end, and that pleasure was the only perfect good. Epicurus also says that the removal of pain is pleasure.”
Lactantius, Divine Institutes, III.7.7: “Epicurus thinks that the highest good is in the pleasure of the mind. Aristippus holds that it is in the pleasure of the body.”
Lactantius, Divine Institutes, III.17.38: [Epicurus says, in effect:] “Let us serve pleasure, then, in whatever way we can, for in a short time we will be nothing whatsoever. Let us suffer no day, therefore, no point of time to flow by for us without pleasure, lest, since we ourselves are at sometime to perish, the very fact that we live may perish.” Although he does not say this in so many words, however, he teaches this is fact.”
Plutarch, On Peace of Mind, 2 p. 465F (Johannes Stobaeus, Anthology, 29.79): For this reason not even Epicurus believes that men who are eager for honor and glory should lead an inactive life, but that they should fulfill their natures by engaging in politics and entering public life, on the ground that, because of their natural dispositions, they are more likely to be disturbed and harmed by inactivity if they do not obtain what they desire.
