Bonaventure

Therefore he adds: "Words are very many," that is, few things are known: below, chapter 10: "The fool multiplies words." "And having much vanity in disputing," and little truth, above, chapter 3: "He has delivered the world to their disputation, so that man may not find the work which God has wrought from the beginning even to the end"; and therefore those who wish to scrutinize these things become vain, according to that word of the Apostle in First Corinthians 3: "God knows the thoughts of the wise, that they are vain."
