Translated by F. M. Padelford.
To speak generally and so far as your needs demand, purity of soul embraces these things: to scorn sensual pleasures, to refuse to feast the eyes on the senseless antics of buffoons, or on bodies which goad one to passion, and to close one's ears to songs which corrupt the mind. For passions which are the offspring of servility and baseness are produced by this kind of music. On the other hand, we must employ that class of music which is better in itself and which leads to better things, which David, the sacred psalmist, is said to have used to assuage the madness of the king. Also tradition has it that when Pythagoras happened upon some drunken revelers, he commanded the flute-player, who led the merry-making, to change the tune and to play a Doric air, and that the chant so sobered them that they threw down their wreaths, and shamefacedly returned home. Others at the sound of the flute rave like Corybantes and Bacchantes. Even so great a difference does it make whether one lends his ear to healthy or to vicious music. Therefore you ought to have still less to do with the music of such influence than with other infamous things. Then I am ashamed to forbid you to load the air with all kinds of sweet-smelling perfumes, or to smear yourselves with ointment. Again, what further argument is needed against seeking the gratification of one's appetite than that it compels those who pursue it, like animals, to make of their bellies a god?
In a word, he who would not bury himself in the mire of sensuality must deem the whole body of little worth, or must, as Plato puts it, pay only so much heed to the body as is an aid to wisdom, or as Paul admonishes somewhere in a similar passage: 'Let no one make provision for the flesh, to fulfill the lusts thereof.' Wherein is there any difference between those who take pains that the body shall be perfect, but ignore the soul, for the use of which it is designed, and those who are scrupulous about their tools, but neglectful of their trade? On the contrary, one ought to discipline the flesh and hold it under, as a fierce animal is controlled, and to quiet, by the lash of reason, the unrest which it engenders in the soul, and not, by giving full rein to pleasure, to disregard the mind, as a charioteer is run away with by unmanageable and frenzied horses. So let us bear in mind the remark of Pythagoras, who, upon learning that one of his followers was growing very fleshy from gymnastics and hearty eating, said to him, 'Will you not stop making your imprisonment harder for yourself?' Then it is said that since Plato foresaw the dangerous influence of the body, he chose an unhealthy part of Athens for his Academy, in order to remove excessive bodily comfort, as one prunes the rank shoots of the vines. Indeed I have even heard physicians say that over-healthiness is dangerous. Since, then, this exaggerated care of the body is harmful to the body itself, and a hindrance to the soul, it is sheer madness to be a slave to the body, and serve it.
