[243] And what is here said is not a cunningly devised fable, but is rather one of the most completely true facts, which may be seen to be true in our own selves. For it very often happens that the outward senses observe a sort of confederacy which they have formed with the passions, supplying them with objects perceptible by the outward senses; and very often also, they raise contentions, no longer choosing to pay the tribute fairly due from them, or else being unable to do so, by reason of the presence of corrective reason; which when it has taken up its complete armour, namely, the virtues, and their doctrines and contemplations, which form an irresistible power, conquers all things in the most vigorous manner. For it is not lawful for perishable things to dwell with what is immortal.
