Abstract
Esperanto was conceived as a model of commercial usefulness, but also to confront the higher aims of its “internal idea.” The <em>interna ideo</em> of Esperanto has historically taken various forms, but it has most often been concerned with protecting a multiethnic world in its diversities, building bridges that allow for a more equitable coexistence of minorities. This underlying ethical thrust makes the international language a potential lever for a more just society in the current global conditions. In order to support this claim, I reconstruct the rhetorical situation of Zamenhof’s pronouncements on the “internal idea,” including Hillelism and Homaranismo. I also argue that George Orwell’s dystopic Newspeak can be considered a political commentary about what would happen to Esperanto if the “internal idea” were to be hijacked in the name of economic progress or the supposed tranquility of commerce.
