"My warnings have been of little effect; and such is the influence of evil communications, that I myself cannot help pleading guilty of having occasionally used linguistic terms in an ethnological sense. Still it is an evil that ought to be resisted with all our might. Ethnologists persist in writing of Aryas, Shemites and Turanians, Ugrians, Dravidians, Kolarians, Bantu races and c., forgetting that these terms have nothing to do with blood, or bones, or hair, or facial angles, but simply and solely with language. Aryas are those who speak Aryan languages, whatever their color, whatever their blood. In calling them Aryas we predicate nothing of them except that the grammar of their language is Aryan. The classification of Aryas and Shemites is based on linguistic grounds and on nothing else; and it is only because languages must be spoken by somebody that we may allow ourselves to speak of language as synonymous with peoples."
