The same argument holds good with regard to intellectual pleasures; the same law operates. We see men who are the flower of their age in intellect, who pass beyond their fellows and tower over them, entering at last upon a fatal treadmill of thought, where they yield to the innate indolence of the soul and begin to delude themselves by the solace of repetition. Then comes the barrenness and lack of vitality,—that unhappy and disappointing state into which great men too often enter when middle life is just passed.
