For he that makes any thing his chiefest good, wherein justice or virtue does not bear a part, and sets up profit, not honesty, for the measure of his happiness; as long as he acts in conformity with his own principles, and is not overruled by the mere dictates of reason and humanity, can never do the offices of friendship, justice, or liberality: nor can he ever be a man of courage, who thinks that pain is the greatest evil; or he of temperance, who imagines pleasure to be the sovereign good.

[Nam qui summum bonum sic instituit, ut nihil habeat cum virtute coniunctum, idque suis commodis, non honestate metitur, hic, si sibi ipse consentiat et non interdum naturae bonitate vincatur neque amicitiam colere possit nec iustitiam nec liberalitatem; fortis vero dolorem summum malum iudicans aut temperans voluptatem summum bonum statuens esse certe nullo modo potest.]

Marcus Tullius Cicero (106-43 BC) Roman orator, statesman, philosopher

De Officiis [On Duties; On Moral Duty; The Offices], Book 1, ch. 2 (1.2) / sec. 5 (44 BC) [tr. Cockman (1699)]

Attacking the Epicurean "highest good" of avoiding pain and seeking personal detachment; Cicero supported the Stoic virtues of courage and moderation.

(Source (Latin)). Alternate translations:

He who teaches that to be the chief good which hath no connection with virtue, which is measured by personal advantage, and not by honor; if he be consistent with himself, and not sometimes overcome by the benignity of nature, can neither cultivate friendship nor practice justice nor liberality. That man cannot be brave who believes pain the greatest evil; nor temperate, who believes pleasure the supreme good.
[tr. McCartney (1798)]

For if a man should lay down as the chief good, that which has no connexion with virtue, and measure it by his own interests, and not according to its moral merit; if such a man shall act consistently with his own principles, and is not sometimes influenced by the good ness of his heart, he can cultivate neither friendship, justice, nor generosity. In truth, it is impossible for the man to be brave who shall pronounce pain to be the greatest evil, or temperate who shall propose pleasure as the highest good.
[tr. Edmonds (1865)]

For he who so interprets the supreme good as to disjoin it from virtue, and measures it by his own convenience, and not by the standard of right, -- he, I say, if he be consistent with himself, and be not sometimes overcome by natural goodness, can cultivate neither friendship, nor justice, nor generosity; nor can he possibly be brave while he esteems pain as the greatest of evils, or temperate while he regards pleasure as the supreme good.
[tr. Peabody (1883)]

He who severs the highest good from virtue and measures it by interest and not by honour, if he were true to his principles and did not at times yield to his better nature, could not cultivate friendship, justice or liberality; and no one can be brave who declares pain the greatest evil, or temperate who maintains pleasure to be the highest good.
[tr. Gardiner (1899)]

For he who posits the supreme good as having no connection with virtue and measures it not by a moral standard but by his own interests -- if he should be consistent and not rather at times over-ruled by his better nature, he could value neither friendship nor justice nor generosity; and brave he surely cannot possibly be that counts pain the supreme evil, nor temperate he that holds pleasure to be the supreme good.
[tr. Miller (1913)]

Take, for example, the man who has established the kind of highest good that has nothing to do with virtue, that is, measured by the individual's convenience, not by his morality. If that man is consistent and is not in the meantime overcome by natural goodness, he cannot cultivate friendship, or justice, or openness of character. In fact, a man of courage who considers pain the greatest evil, or a temperate man who declares indulgence to be the greatest good, is surely an impossible contradiction.
[tr. Edinger (1974)]

No man can be brave who thinks pain the greatest evil; nor temperate, who considers pleasure the highest good.
