According to Rado, Esperanto is a neutral language. He explains that Esperanto is used to a common language with a million speakers globally while they are punishing in Germany, Japan and Russia. In the contrast, Sola claims that Esperanto is only historical misfortune held it back. She states that Esperanto supported by china but not many people use it.
Sola and Rado both discuss the spread of Esperanto but have very different opinions about Esperanto. While Rado states that Esperanto is a neutral language, Sola states that Esperanto is only historical misfortune held it back. Rado indicates that there are millions of Esperanto speakers globally. It seems that he just general the number of speakers and also is biased because he is president of “Esperanto Now” group so he have to save and spread this language. In addition, As Sola states, “if [one can] use Esperanto as form, and use it to advance the causes of internationalism and real revolution, then Esperanto may be learned, and should be learned” (David 2003). In fact, if Esperanto used as a real revolution, it can become a global language. Therefore, Esperanto can not be a neutral language.
Sola argues that waste of time to learn Esperanto.
