... il n'est rien creu si fermement que ce qu'on sçait le moins, ... - Michel de Montaigne

To call out for the hand of the enemy is a rather extreme measure, yet a better one, I think, than to remain in continual fever over an accident that has no remedy. But since all the precautions that a man can take are full of uneasiness and uncertainty, it is better to prepare with fine assurance for the worst that can happen, and derive some consolation from the fact that we are not sure that it will happen.

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.

To which we may add this other Aristotelian consideration, that he who confers a benefit on any one loves him better than he is beloved by him again.
