These are his sentiments about the things which concern the life of man, and he has discussed them at greater length elsewhere.
XXVIII. Now, he differs with the Cyrenaics about pleasure. For they do not admit that to be pleasure which exists as a condition, but place it wholly in motion. He, however, admits both kinds to be pleasure, namely, that of the soul, and that of the body, as he says in his treatise on Choice and Avoidance; and also in his work on the Chief Good; and in the first book of his treatise on Lives, and in his Letter against the Mitylenian Philosophers. And in the same spirit, Diogenes, in the seventeenth book of his Select Discourses, and Metrodorus, in his Timocrates, speak thus. “But when pleasure is understood, I mean both that which exists in motion, and that which is a state.…” And Epicurus, in his treatise on Choice, speaks thus: “Now, freedom from disquietude, and freedom from pain, are states of pleasure; but joy and cheerfulness are beheld in motion and energy.”
XXIX. For they make out the pains of the body to be worse than those of the mind; accordingly, those who do wrong, are punished in the body. But he considers the pains of the soul the worst; for that the flesh is only sensible to present affliction, but the soul feels the past, the present, and the future. Therefore, in the same manner, he contends that the pleasures of the soul are greater than those of the body; and he uses as a proof that pleasure is the chief good, the fact that all animals from the moment of their birth are delighted with pleasure, and are offended with pain by their natural instinct, and without the employment of reason. Therefore, too, we, of our own inclination, flee from pain; so that Hercules, when devoured by his poisoned tunic, cries out:—
Shouting and groaning, and the rocks around
Re-echoed his sad wails, the mountain heights
Of Locrian lands, and sad Eubœa’s hills.[143]
XXX. And we choose the virtues for the sake of pleasure, and not on their own account; just as we seek the skill of the physician for the sake of health, as Diogenes says, in the twentieth book of his Select Discourses, where he also calls virtue a way of passing one’s life (διαγωγή). But Epicurus says, that virtue alone is inseparable from pleasure, but that every thing else may be separated from it as mortal.
XXXI. Let us, however, now add the finishing stroke, as one may say, to this whole treatise, and to the life of the philosopher; giving some of his fundamental maxims, and closing the whole work with them, taking that for our end which is the beginning of happiness.
1. “That which is happy and imperishable, neither has trouble itself, nor does it cause it to anything; so that it is not subject to the feelings of either anger or gratitude; for these feelings only exist in what is weak.
(In other passages he says that the Gods are speculated on by reason, some existing according to number, and others according to some similarity of form, arising from the continual flowing on of similar images, perfected for this very purpose in human form.)
