I do not approve of antisemitism; it is a narrow, one-sided view, still I have sought to account for it. It has flourished in all countries and in all ages, before and after the Christian era, at Alexandria, Rome, and Antiachia, in Arabia, and in Persia, in medieval and modern Europe, in a word, in all parts of the world wherever there are or have been Jews. Such an opinion, it seemed to me, could not spring from a mere whim or fancy, but must be the effect of deep and serious causes.
