My advice to all who have the time or inclination to concern themselves with the international language movement would be: back Esperanto loyally.
J R R Tolkien
Esperanto was a very useful language, because wherever you went, you found someone to speak with.
I am for a world calendar, as I am for a unique currency for all peoples and for a global auxiliary language like Esperanto for everyone.
Esperanto is the best solution for the idea of an international language.
I consider myself a soldier of Esperanto. It doesn't matter if you are not many, your idea will win. It will win because it's right. Every nation has its own language, humanity has to have its own, Esperanto.
Probably a neutral language would be more useful as tool of communication between the nations in the world. Esperanto is already from long time the main candidate for this function.
Esperanto is the only supranational living language of our age.
Pope John XIII
I have enough belief in the present and hope in the future to say by all means let us learn Esperanto...
