"Of late, men seem to have been possessed by an incomprehensible impulse to strip themselves of everything with which nature has endowed them in order to make them superior to the beasts of burden. A philosopher is a gentleman who sits down four times a day to the best meals he can possibly obtain, and who considers that virtue, glory and noble sentiments should be indulged in only when they do not interfere with those four indispensable functions and all the rest of his little personal comforts. At this rate, a mule is a better philosopher by far, because in addition to all this he puts up with blows and hardship without complaint."
