….He gradually grew to feel that it had not been the most direful mistake in his plan of education. Something must have been wanting within, or time would have worn away much of its ill effect. He feared that principle, active principle, had been wanting; that they had never been properly taught to govern their inclinations and tempers by that sense of duty which can alone suffice. They had been instructed theoretically in their religion, but never required to bring it into daily practice. To be distinguished for elegance and accomplishments, the authorised object of their youth, could have no useful influence that way, no moral effect on the mind. He had meant them to be good, but his cares had been directed to the understanding and manners, not the disposition; and of the necessity of self-denial and humility, he feared they never heard from any lips that could profit them.
