Unfortunately the Fundamentists persist in their obstinacy and continue to manifest their discontent. Although the new language has sprung from Esperanto and is based upon it, the Esperantists have forbidden that the name Esperanto should be used. The conventional name _Ido_ (_i.e._, a descendant) has therefore been given to it. There exist already some periodicals in the _linguo internaciona_. The chief organ of the new movement is the periodical _Progreso_ (pronounced _Progresso_), "_oficiala organo di la Delegitaro por adopto di linguo helpanta internaciona_." It is edited by Professor L. Couturat in Paris, and owes its name, programme, and policy to the advice and initiative of Ostwald. The superiority of Ido over Esperanto is so striking and is so incontestably borne out by practical experience that one can now really speak, after the Volapük and Esperanto periods, of a third world-language movement which has started off with a reaction-velocity hitherto unknown in this department of knowledge. It is characteristic of the new language that it has been taken up by the English and Americans, whilst an introduction of primitive Esperanto amongst the Anglo-Saxons encountered insuperable obstacles, for, as was pointed out with good reason, the English language, especially in regard to its grammar, was superior to Esperanto on account of a number of clumsy constructions and errors which the latter contained. But, apart from the regularity of pronunciation, Ido excels the English language both in regard to grammar and, what is of great importance, brevity, a printed Ido text being even briefer than the corresponding English one. For the benefit of those who are unacquainted with the nature of international language and who still regard an artificial language as an impossible monstrosity, we may remark that the new vocabulary contains in round numbers 5,400 stems, and that, in spite of the Romance character which the international language necessarily possesses, 40 per cent. of these are common to the following six languages: German, English, French, Italian, Russian, Spanish (and to many others). Moreover, there are naturally innumerable other stems which occur simultaneously in five or four of the great languages. In the face of this overwhelming evidence, no one can contest the possibility of an international language, for the above numbers tell their tale with unmistakable clearness. They _prove the existence of the international language apart from every theory_. It is only necessary to select judiciously the words common to the living languages, that is to say, by an artificial process, in order to construct the international language.
