Let me excuse myself for saying what I often repeat, that I rarely repent, and that my conscience is content with itself, not as the conscience of an angel or a horse, but as the conscience of a man; though always with the addition of this refrain--which is no formal refrain but a true and sincere confession--that I speak as one who questions and does not know, referring the decision purely and simply to common and authorized belief. I do not teach, I relate. (Michel de Montaigne, "On Repentance," Essays 3.2; trans. J.M. Cohen)
Sounds like he is using Socrates as his model here as one who claims not to know, and as one who does not teach, but always questions.
