Advantage..........................

The achievement of the self-taught man remains wonderful, but, if he surmounts his difficulties at all, some of his limitations may turn to sheer advantage.  There is some advantage merely in being driven to make the most of his few books; great advantage in having one's choice restricted by circumstances to good books; a great advantage too in the consciousness of untrained faculty which leaves a man capable in mature life of deliberately undertaking mental discipline.
