"The struggles in early Rome between Latin and Etruscan, and the endless quarrels between patrician and plebeian, arose from the existence in Rome, side by side, of two distinct and clashing races, probably Nordic and Mediterranean respectively. The northern qualities of Rome are in sharp contrast to the Levantine traits of the classic Greeks, whose volatile and analytical spirit, lack of cohesion, political incapacity, and ready resort to treason, all point clearly to southern and eastern affinities."
