Hi Mr. Floro. First of all, sorry for my English, but here in Spain the English only appears in the Stop road sign.
I'm in disagree with this text. I don't think that it would be a good idea get a common language for all the world. A language has an "useful" feature in order to allow the communication among the people, ok, but each language has a "cultural" feature as well. You cannot compare a language with a system of measurement. A language includes the idiosyncrasy of a country. This set of words isn't a random set of chars. Moreover, if you forget a language you're stealing to your children the posibility of enjoying with all the literature and essays written in that language for centuries. I don't accept the posibility of translation: it isn't the same.
As I said once, I think that a language is similar to a paintbrush. It has a utility: you can paint your room. But with this brush you can also make a beautiful picture expressing you feelings, a complaint, a place...
With a difference: if you lost this paintbrush, not only your children won't be able draw as you did, but also you lost the ability of enjoying with the pictures that you draw before.
I hope you understand me: It's difficult to me to express in this language.
Bye!
