The psychology of a language which, in one way or another, is imposed upon one because of factors beyond one's control, is very different from the psychology of a language which one accepts of one's free will.

As a matter of fact, a national language which spreads beyond its own confines very quickly loses much of its original richness of content and is in no better case than a constructed language.

A standard international language should not only be simple, regular, and logical, but also rich and creative.
