William Dwight Whitney,
Language and the Study of Language
(1867)
“ And, in all these respects, the study of language need fear a comparison with no one of the physical sciences. Its field is the speech of all mankind, cultivated or savage; the thousands of existing dialects, with all their recorded predecessors; the countless multitudes of details furnished by these, each significant of a fact in human history, external or internal. The wealth of languages is like the wealth of species in the whole animal kingdom. ”
