Emulation, even in brutes, is sensitively "nervous." See the tremor of the thoroughbred racer before he starts. The dray-horse does not tremble, but he does not emulate. It is not his work to run a race. Says Marcus Antoninus, "It is all one to a stone whether it be thrown upward or downward." Yet the emulation of a man of genius is seldom with his contemporaries, that is, inwardly in his mind, although outwardly in his act it would seem so. The competitors with whom his secret ambition seems to vie are the dead.
