Roger Bacon’s thirst for knowledge was not lust: he wanted to employ his learning to make God’s people happier, and so he did not seek knowledge for its own sake. Benno’s is merely insatiable curiosity, intellectual pride, another way for a monk to transform and allay the desires of his loins, or the ardor that makes another man a warrior of the faith or of heresy. There is lust not only of the flesh. Bernard Gui is lustful; his is a distorted lust for justice that becomes identified with a lust for power. Our holy and no longer Roman Pontiff lusts for riches.
