English, especially, was claimed by many, some twenty years ago, to be not merely the auxiliary language of the future, but the universal language which must spread all over the world and supersede and drive out all others by a kind of survival of the fittest. This notion of a universal language is now everywhere regarded as a delusion, but at that time there was still thought by many to be a kind of special procreative activity in the communities of Anglo-Saxon origin which would naturally tend to replace all other peoples, both the people and the language being regarded as the fittest to survive.[239] English was, however, rightly felt to be a language with very great force behind it, being spoken by vast communities possessing a peculiarly energetic and progressive temperament, and with much power of peaceful penetration in other lands. It is generally acknowledged also that English fully deserves to be ranked as one of the first of languages by its fine aptitude for powerful expression, while at the same time it is equally fitted for routine commercial purposes. The wide extension of English and its fine qualities have often been emphasized, and it is unnecessary to dwell on them here. The decision of the scientific societies of the world to use English for bibliographical purposes is not entirely a tribute to English energy in organization, but to the quality of the language. One finds, indeed, that these facts are widely recognized abroad, in France and elsewhere, though I have noted that those who foretell the conquest of English, even when they are men of intellectual distinction and able to read English, are often quite unable to speak it or to understand it when spoken.
