“Of all the foolish things that parents say about their children, there is none worse than the common saying, ‘My son has a good heart at the bottom. He is not what he ought to be; but he has fallen into bad hands. Public schools are bad places. The tutors neglect the boys. Yet he has a good heart at the bottom.” The truth, unhappily, is diametrically the other way. The first cause of all sin lies in the natural corruption of the boy’s own heart, and not in the school.”
