The French have their own form of this pseudo-science in their doctrine of the persistence of national characteristics. Each nation may be summed up in a formula: England, for example, is 'the country of will.' A few instances may, no doubt, be quoted in support of this theory. Julius Caesar said: 'Duas res plerasque Gallia industriosissime prosequitur, rem militarem et argute loqui'; and these are still the characteristics of our gallant allies. And Madame de Stael may be thought to have hit off the German character very cleverly about the time when Bismarck first saw the light. 'The Germans are vigorously submissive. They employ philosophical reasonings to explain what is the least philosophic thing in the world, respect for force and the fear which transforms that respect into admiration.' But the fact remains that the characters of nations frequently change, or rather that what we call national character is usually only the policy of the governing class, forced upon it by circumstances, or the manner of living which climate, geographical position, and other external causes have made necessary for the inhabitants of a country. To found patriotism on homogeneity of race is no wiser than to bound it by frontier lines. As the Abbe Noel has lately written about his own country, Belgium, the race is not the nation. The nation is not a physiological fact; it is a moral fact. What constitutes a nation is the community of sentiments and ideals which results from a common history and education. The variations of the cephalic index are here of no great importance. The essential factor of the national consciousness resides in a certain common mode of conceiving the conditions of the social life.
