Context

“If the study of languages were merely the study of words, that is, of the symbols by which language expresses itself, then this might be a suitable study for children; but languages, as they change the symbols, also modify the ideas which the symbols express. Minds are formed by language, thoughts take their colour from its ideas. Reason alone is common to all. Every language has its own form, a difference which may be partly cause and partly effect of differences in national character; this conjecture appears to be confirmed by the fact that in every nation under the sun speech follows the changes of manners, and is preserved or altered along with them.” source
