Review for Slate Book Review of Esther Schor's Bridge of Words:

As Princeton literature professor Esther Schor shows in her combined history of the language and memoir of her seven-year encounter with it, Bridge of Words, the success of Esperanto might be measured less in what it did for humanity at large and more in what it did, and continues to do, for its speakers, including Schor herself. Esperanto may not have changed the world. But in both its ideals and its practice, it holds out the possibility of transforming the lives of the people who use it.
