[ Footnote 183: ] By working back from such data as we possess we can make it probable that these languages were originally confined to a comparatively small area in northern Germany and Scandinavia. This area is clearly marginal to the total area of distribution of the Indo-European-speaking peoples. Their center of gravity, say 1000 B.C., seems to have lain in southern Russia.

[ Footnote 184: ] While this is only a theory, the technical evidence for it is stronger than one might suppose. There are a surprising number of common and characteristic Germanic words which cannot be connected with known Indo-European radical elements and which may well be survivals of the hypothetical pre-Germanic language; such are house, stone, sea, wife (German Haus, Stein, See, Weib).

[ Footnote 185: ] Only the easternmost part of this island is occupied by Melanesian-speaking Papuans.

[ Footnote 186: ] A “nationality” is a major, sentimentally unified, group. The historical factors that lead to the feeling of national unity are various—political, cultural, linguistic, geographic, sometimes specifically religious. True racial factors also may enter in, though the accent on “race” has generally a psychological rather than a strictly biological value. In an area dominated by the national sentiment there is a tendency for language and culture to become uniform and specific, so that linguistic and cultural boundaries at least tend to coincide. Even at best, however, the linguistic unification is never absolute, while the cultural unity is apt to be superficial, of a quasi-political nature, rather than deep and far-reaching.

[ Footnote 187: ] The Semitic languages, idiosyncratic as they are, are no more definitely ear-marked.

[ Footnote 188: ] See [page 209].

[ Footnote 189: ] The Fijians, for instance, while of Papuan (negroid) race, are Polynesian rather than Melanesian in their cultural and linguistic affinities.

[ Footnote 190: ] Though even here there is some significant overlapping. The southernmost Eskimo of Alaska were assimilated in culture to their Tlingit neighbors. In northeastern Siberia, too, there is no sharp cultural line between the Eskimo and the Chukchi.

[ Footnote 191: ] The supersession of one language by another is of course not truly a matter of linguistic assimilation.

[ Footnote 192: ] “Temperament” is a difficult term to work with. A great deal of what is loosely charged to national “temperament” is really nothing but customary behavior, the effect of traditional ideals of conduct. In a culture, for instance, that does not look kindly upon demonstrativeness, the natural tendency to the display of emotion becomes more than normally inhibited. It would be quite misleading to argue from the customary inhibition, a cultural fact, to the native temperament. But ordinarily we can get at human conduct only as it is culturally modified. Temperament in the raw is a highly elusive thing.
