He further disagrees with the Cyrenaics in that they hold that pains of body are worse than mental pains; at all events evil-doers are made to suffer bodily punishment; whereas Epicurus holds the pains of the mind to be the worse; at any rate the flesh endures the storms of the present alone, the mind those of the past and future as well as the present. In this way also he holds mental pleasures to be greater than those of the body. And as proof that pleasure is the end he adduces the fact that living things, so soon as they are born, are well content with pleasure and are at enmity with pain, by the prompting of nature and apart from reason. Left to our own feelings, then, we shun pain; as when even Heracles, devoured by the poisoned robe, cries aloud, And bites and yells, and rock to rock resounds, Headlands of Locris and Euboean cliffs.Soph. Trach. 787 f.; but our mss. read βοῶν for δάκνων.

And we choose the virtues too on account of pleasure and not for their own sake, as we take medicine for the sake of health. So too in the twentieth book of his Epilecta says Diogenes, who also calls education (ἀγωγή) recreation (διαγωγή). Epicurus describes virtue as the sine qua non of pleasure, i.e. the one thing without which pleasure cannot be, everything else, food, for instance, being separable, i.e. not indispensable to pleasure.
