“Many are deceived by the desire to appear wise before their time. They therefore break out in a certain swollen importance and begin to simulate what they are not and to be ashamed of what they are; and they slip all the farther from wisdom in proportion as they think, not of being wise, but of being thought so. I have known many of this sort who, although they still lacked the very rudiments of learning, yet deigned to concern themselves only with the highest problems, and they supposed that they themselves were well on the road to greatness simply because they had read the writings or heard the words of great and wise men.”
Hugh of St. Victor, Didascalicon, Book III, Chapter 13: “Concerning Humility”.
