Without a party, a statesman is nothing. He sometimes forgets that awkward fact. If the leader or principal agent of a faction goes beyond the wishes of his allies and emancipates himself from control, he may have to be dropped or suppressed. The reformer Ti. Gracchus was put up by a small group of influential consulars. These prudent men soon refused further support to the rash, self-righteous tribune when he plunged into illegal courses. The political dynast Crassus used Catilina as his agent. Catilina could not, or would not, understand that reform or revolution had no place in the designs of his employer. Crassus drew back, and Catilina went on, to his ruin.
