Objections are raised both by professional philologists (linguists) and by laymen. Among the former I must here specially mention the two leaders of German comparative linguistics, Brugmann and Leskien, but their attacks were made at the time when Esperanto was beginning to gain favour, and later languages have avoided not a few of the imperfections found fault with by the two Leipzig professors. In 1925 Professor G. Güntert in his Grundfragen der Sprachwissenschaft tried to reduce the whole idea ad absurdum, but on the basis of so deficient a knowledge of the facts of the case and with so prejudiced a mind that he proved less than nothing. It would be a very great mistake to suppose that professional philologists as a body are against constructed languages; it would be much more correct to say that those among them who have gone most into the question are the best disposed to them. - Otto Jespersen, An International Language, 1928]
