esperanto_story1-4, Exercise 2: The inner idea (about 100 words)

Model answer (check the details):

The "inner idea" (interna ideo) was the hope, strongly felt by Zamenhof, that a shared neutral language would help peoples see each other as brothers. He explored it in his hymn, speeches and two proposals: Hillelism (1901, 1906), a moral teaching drawn from Judaism and meant to unite people, and Homaranism (1913), a declaration of ethical commitment across religions and nations without a new church. Neither became a movement. Some Esperantists welcomed his idealism; others feared that tying the language to a creed would conflict with the Declaration of Boulogne, which said that Esperantism had no political or religious programme. His own position was that the language was neutral and the ideal was a personal view.

Care: describe the views from his published words, and avoid claims about his private beliefs.
