Those who write about the Greeks must beware of a heresy which is very rife just now--the theory of _racialism_. Political ethnology, which is no genuine science, excused the ambition of the Germans to themselves, and helped them to wage war; it has suggested to the Allies a method of waging peace. The false and mischievous doctrine of superior and inferior races is used to justify oppression in Europe, and murder by torture in America. It will not help us to understand the Greeks. The Greeks were a nation of splendid mongrels, made up of the same elements, differently mixed, as ourselves. Their famous beauty, which had almost disappeared when Cicero visited Athens, was mainly the result of a healthy outdoor life and physical training, combined with a very becoming costume. They were probably not handsomer than Oxford rowing crews or Eton boys. Their flowering time of genius was due to the same causes which produced similar results in the Italian Renaissance. The city-state is a forcing-house of brilliant achievement, though it quickly uses up its human material. We cannot even regard the Greeks as a homogeneous mixed race. The Spartiates were almost pure Nordics; the Athenians almost pure Mediterraneans. The early colonists, from whom sprang so many of the greatest names in the Hellenic roll of honour, are not likely to have kept their blood pure. Nor was there ever a Greek culture shared by all the Greeks. The Spartan system, that of a small fighting tribe encamped in a subject country, recalls that of Chaka's Zulus; Arcadia was bucolic, Aetolia barbarous, Boeotia stolid, Macedonia half outside the pale. The consciousness of race among the Greeks counted practically for about as much as the consciousness of being white men, or Christians, does in modern civilization.
