Every piece of marble has a statue in it waiting to be released by a person of sufficient skill to chip away the unnecessary parts. Just as the sculptor is to the marble, so is education to the soul. It releases it. For only educated people are free people. You cannot create a statue by smashing the marble with a hammer, and you cannot by the force of arms release the spirit or the soul of people.
Because the newer methods of treatment are good, it does not follow that the old ones were bad: for if our honorable and worshipful ancestors had not recovered from their ailments, you and I would not be here today.
