In eloquence, the great triumphs of the art are when the orator is lifted above himself; when consciously he makes himself the mere tongue of the occasion and the hour, and says what cannot but be said. Hence the term "abandonment" to describe the self- surrender of the orator. Not his will, but the principle on which he is horsed, the great connection and crisis of events, thunder in the ear of the crowd.
