“The genius,” Schopenhauer wrote in his timeless distinction between genius and talent,
lights on his age like a comet into the paths of the planets, to whose well-regulated and comprehensible arrangement its wholly eccentric course is foreign.
Unlike the work of talent, which simply exceeds in excellence the work of contemporaries and is therefore easily appreciated by them, Schopenhauer argued that a work of genius differs not in mere degree of excellence but in kind of vision. It is therefore often ridiculed or, worse yet, entirely ignored by contemporaries, to be rediscovered and appreciated only by posterity.
