De Agricultura

For the indulgences of intemperance and gluttony, and whatever other vices the immoderate and insatiable pleasures, when completely filled with an abundance of all external things, produce and bring forth, do not allow the soul to proceed onwards by the plain and straight road, but compel it to fall into ravines and gulfs, until they utterly destroy it; but those practises which adhere to patience, and endurance, and moderation, and all other virtues, keep the soul in the straight road, leaving no stumbling block in the way, against which it can stumble and fall. Very naturally, therefore, has Moses declared that temperance clings to the right way, because it is plain that the contrary habit, intemperance, is always straying from the road.
