Far from it; for Saxony is its culminating center; and Saxony, as we know, is really half-Slavic at heart, as is also eastern Prussia. Suicide should be most frequent in Schleswig-Holstein and Hanover, if racial causes were appreciably operative. The argument, in fact, falls to pieces of its own weight, as Durkheim has shown. His conclusion is thus stated: "If the Germans are more addicted to suicide, it is not because of the blood in their veins, but of the civilization in which they have been raised." A summary view of the class of social phenomena seemingly characteristic of the distinct races in France, if we extend our field of vision to cover all Europe, suggests an explanation for the curious coincidences and parallelisms noted above, which is the exact opposite of the racial one. Our theory, then, is this: that most of the social phenomena we have noted as peculiar to the areas occupied by the Alpine type are the necessary outcome, not of racial proclivities but rather of the geographical and social isolation characteristic of the habitat of this race. The ethnic type is still pure for the very same reason that social phenomena are primitive. Wooden ploughs pointed with stone, blood revenge, an undiminished birth-rate, and relative purity of physical type are all alike derivatives from a common cause, isolation, directly physical and coincidently social. We discover, primarily, an influence of environment where others perceive phenomena of ethnic inheritance. 4. Natural versus Vicinal Location in National Development[115] In contradistinction to continental and intercontinental location, anthropogeography recognizes two other narrower meanings of the term. The innate mobility of the human race, due primarily to the eternal food-quest and increase of numbers, leads a people to spread out over a territory till they reach the barriers which nature has set up, or meet the frontiers of other tribes and nations. Their habitat or their specific geographic location is thus defined by natural features of mountain, desert, and sea, or by the neighbors whom they are unable to displace, or more often by both.
