“People with new ideas, people with the faintest capacity for saying something new, are extremely few in number, extraordinarily so in fact. One thing only is clear, that the appearance of all these grades and sub-divisions of men must follow with unfailing regularity some law of nature. That law, of course, is unknown at present, but I am convinced that it exists, and one day may become known. The vast mass of mankind is mere material and only exists in order by some great effort, by some mysterious process, by means of some crossing of races and stocks, to bring into the world at last perhaps one man out of a thousand with a spark of independence. One in ten thousand perhaps—I speak roughly, approximately—is born with some independence, and with still greater independence one in a hundred thousand. The man of genius is one of the millions, and the great geniuses, the crown of humanity, appear on earth perhaps one in many thousand million. In fact, I have not peeped into the retort in which all this takes place. But there certainly is and must be a definite law, it cannot be a matter of chance. ”
