Not being able to govern events, I govern myself. Nothing is so firmly believed as that which we least know. To philosophize is to doubt. It is good to rub and polish our brain against that of others. There is no conversation more boring than the one where everybody agrees. I prefer the company of peasants because they have not been educated sufficiently to reason incorrectly. There are some defeats more triumphant than victories. I quote others only in order the better to express myself. Wise men have more to learn of fools than fools of wise men.
