...Jews seem to have superiority as actors, chess-players, doctors, merchants (chiefly financiers), in metaphysics, music, poetry, and philology.... Of course, Jews have no Darwin. It took England 180 years after Newton before she could produce a Darwin, and as Britishers are five times the number of Jews, even including those of Russia, it would take, on the same showing, 900 years before they produce another Spinoza, or, even supposing the double superiority to be true, 450 years would be needed.
