“This is academic humility: the knowledge that anyone can teach us something. Perhaps this is because we are so clever that we succeed in having someone less skilled than us teach us something; or because even someone who does not seem very clever to us has some hidden skills; or also because someone who inspires us may not inspire others. The reasons are many. The point is that we must listen with respect to anyone, without this exempting us from pronouncing our value judgments; or from the knowledge that an author’s opinion is very different from ours, and that he is ideologically very distant from us. But even the sternest opponent can suggest some ideas to us. It may depend on the weather, the season, and the hour of the day. Perhaps, had I read the abbot Vallet a year before, I would not have caught the hint. And who knows how many people more capable than I had read him without finding anything interesting. But I learned from that episode that if I wanted to do research, as a matter of principle I should not exclude any source. This is what I call academic humility. Maybe this is hypocritical because it actually requires pride rather than humility, but do not linger on moral questions: whether pride or humility, practice it.”
