"One can show that Emerson anticipated many of Nietzsche’s most famous utterances. There is a direct line from Emerson’s “oversoul” to the “overman.” Several decades before Nietzsche wrote, “What does not kill me makes me stronger,” Emerson wrote, “In general, every evil to which we do not succumb, is a benefactor.” More profoundly, Emerson foreshadowed Nietzsche’s concern with the ubiquity of flux and power, and the value of overcoming the past. “Life only avails,” Emerson once wrote, “not the having lived. Power ceases in the instant of repose; it resides in the moment of transitions from a past to a new state.”"
