Quand celui à qui l'on parle ne comprend pas et celui qui parle ne se comprend pas, c'est de la métaphysique When he to whom a person speaks does not understand, and he who speaks does not understand himself, that is metaphysics.
VoltaireThere are barbarians who seize this dog, who so prodigiously surpasses man in friendship, and nail him down to a table, and dissect him alive to show you the mezaraic veins... Answer me, Machinist, has Nature really arranged all the springs of feeling in this animal to the end that he might not feel? Has he nerves that he may be incapable of suffering?
VoltaireWhatever you do, trample down abuses, and love those who love you. Different translation: Whatever you do, crush the infamous thing superstition, and love those who love you.
