A common creation demands a common sacrifice, and perhaps not the least potent argument in favour of a constructed international language is the fact that it is equally foreign, or apparently so, to the traditions of all nationalities.

We see and hear and otherwise experience very largely as we do because the language habits of our community predispose certain choices of interpretation.

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.

Human beings do not live in the objective world alone, nor alone in the world of social activity as ordinarily understood, but are very much at the mercy of the particular language which has become the medium of expression for their society.

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

It is no secret that the fruits of language study are in no sort of relation to the labour spent on teaching and learning them.

Human beings do not wish to be modest; they want to be as expressive - that is, as immodest - as fear allows; fashion helps them solve that paradoxical problem.
