Michel de Montaigne

Great abuses in the world are begotten, or, to speak more boldly, all the abuses of the world are begotten, by our being taught to be afraid of professing our ignorance, and that we are bound to accept all things we are not able to refute: we speak of all things by precepts and decisions. The style at Rome was that even that which a witness deposed to having seen with his own eyes, and what a judge determined with his most certain knowledge, was couched in this form of speaking: “it seems to me.” They make me hate things that are likely, when they would impose them upon me as infallible.
