Yet such facts vary greatly among different races, and the exaggeration which one seems to notice when reading the French sociologists on this point may be due to their observations having been made among a Latin and not a Northern race.
So far I have dealt with the impulses illustrated by the internal politics of a modern State.

But perhaps the most important section in the whole psychology of political impulse is that which is concerned not with the emotional effect of the citizens of any state upon each other, but with those racial feelings which reveal themselves in international politics.

The future peace of the world largely turns on the question whether we have, as is sometimes said and often assumed, an instinctive affection for those human beings whose features and colour are like our own, combined with an instinctive hatred for those who are unlike us.

On this point, pending a careful examination of the evidence by the psychologists, it is difficult to dogmatise.

But I am inclined to think that those strong and apparently simple cases of racial hatred and affection which can certainly be found, are not instances of a specific and universal instinct but the result of several distinct and comparatively weak instincts combined and heightened by habit and association.
