"We still have no evidence on record to prove that great men are endowed with more than the ordinary share of common sense, which is so necessary in conducting the ordinary affairs of life. Indeed, if the gossip of history is to be in any way trusted, great men have usually obtained less than the ordinary share of this commodity. Frederick the Great is reported to have said that, if he wished to ruin one of his provinces, he would hand its government over to the philosophers. Is it into the hands of a Bacon, who had no more sense than to expose himself (for the sake of a little experiment which could have been made just as well without the exposure), a Newton who ordered the grate to be removed when the fire became too hot for him, a Clifford, who worked himself to death, that the direction of the affairs of a people is to be given, with the assurance that they will be carried on better than now?"
