De Decalogo

But the noise, for it is still obscure as it seems, strikes the ear but faintly, not giving forth any more distinct tone by which it may be understood, so that the desire of comprehending it, being unsuccessful and unsatisfied, is excited more and more, the desire causing a Tantalus-like kind of punishment.

For Tantallus, whenever he seemed about to lay his hands on any of the objects which he desired, was invariably disappointed, and the man who is overcome by desire, being always thirsting for what is not present, is never satisfied, wallowing about among vain appetites,

like those diseases which would creep over the whole body, if they were not checked by excision or cautery, and which would overrun and seize upon the whole composition of the body, not leaving a single part in a sound state; in like manner, unless discourse in accordance with philosophy did not, like a good physician, check the influx of appetite, all the affairs of life would of necessity be set in motion in a manner contrary to nature; for there is nothing exempt from such an affliction, nothing which can escape the dominion of passion, but, when once it has obtained immunity and license, it devours everything and becomes by itself everything in every part.
