905. There are great books that are full of moral teachings from which their authors have not derived much moral profit despite helping the progress of humanity. Is the good those authors do by their writings be counted to them as spirits?
“Professing the principles of morality without subsequent action is like having a seed without completing the sowing. What is the point of having the seed, if you do not make it bear fruit to feed you? These authors are even guiltier, because they possess the intelligence that enables them to understand. By not practicing the virtues they recommend to others, they fail to enjoy the harvest they could reap themselves.”
