Mr. Britling Sees It Through, by H. G. Wells, 1916

For his own part he was interested in ideas of universal citizenship, in Esperanto and Ido and universal languages and such-like attacks upon the barriers between man and man.
Herr Heinrich reflected, and received these conclusions with an expression of respectful edification. "I am naturally anxious," he said, "because I am taking tickets for my holidays at an Esperanto Conference at Boulogne."
But Herr Heinrich knew better. "No," he said. "It is the war. It has come. I have heard it talked about in Germany many times. But I have never believed that it was obliged to come. Ach! It considers no one. So long as Esperanto is disregarded, all these things must be."
"If there was only one language in all the world, none of such things would happen," Herr Heinrich declared. "There would be no English, no Germans, no Russians."
"Just Esperantists," said Teddy.
"Or Idoists," said Herr Heinrich. "I am not convinced of which. In some ways Ido is much better."
"Perhaps there would have to be a war between Ido and Esperanto to settle it," said Teddy.
