The Robbers' Cave by Charlotte Maria Tucker

Not the example and influence of Raphael alone tended to ripen good resolutions in the mind of the captive; much resulted from the effect of the long hours of solitude in which reflection was forced upon him. To one of Horace's lively temper and active disposition, meditation had appeared to be of all occupations the most tedious and unprofitable, as long as study or amusement could fill up each waking hour.

It was thus that little wisdom had been gained while a good deal of knowledge had been acquired, and that even the lessons of experience had made but small impression upon Horace Cleveland. He had had his day-dreams, it is true, and his schemes of ambition, but neither had been calmly reviewed in the sober light of truth. Now, having nothing else to do, Horace perforce must think; and the result of reflection was that the proud lad, who, exalted by conscious superiority over his companions, had feared comparison with no one, now felt mortified and even disgusted himself. He recalled circumstances that had once elated him; he remembered the trophies won by intellectual or physical efforts; all their glitter and glory seemed gone.
