Because men do not know the cross and hate it, they necessarily love the opposite, namely, wisdom, glory, power, and so on. Therefore they become increasingly blinded and hardened by such love, for desire cannot be satisfied by the acquisition of those things which it desires. Just as the love of money grows in proportion to the increase of the money itself, so the dropsy of the soul becomes thirstier the more it drinks, as the poet says: “The more water they drink, the more they thirst for it.” The same thought is expressed in Eccles. 1 [:8]: “The eye is not satisfied with seeing, nor the ear filled with hearing.” This holds true of all desires. Thus also the desire for knowledge is not satisfied by the acquisition of wisdom but is stimulated that much more. Likewise the desire for glory is not satisfied by the acquisition of glory, nor is the desire to rule satisfied by power and authority, nor is the desire for praise satisfied by praise, and so on, as Christ shows in John 4 [:13] , where he says, “Every one who drinks of this water will thirst again.” The remedy for curing desire does not lie in satisfying it, but in extinguishing it. In other words, he who wishes to become wise does not seek wisdom by progressing toward it but becomes a fool by retrogressing into seeking folly. Likewise he who wishes to have much power, honor, pleasure, satisfaction in all things must flee rather than seek power, honor, pleasure, and satisfaction in all things. This is the wisdom which is folly to the world.
