I do not understand a man who does not want to know all that he can know. Why would anyone choose ignorance? If he chooses ignorance because he is lay, then he is a fool, for the ignorant are put to hard labor digging and hauling stones for masters who tell them they need no knowledge. If a man must labor from dawn to dusk to avoid a blow on the head and to earn a cup of grain, he has no time to gain knowledge and remains a slave to masters. I think, therefore, that is is a worthy vocation to free a man enough that he can learn who he is and what he is capable of, where he came from and what philosophies steer his life.
