Introduction -- A very strange paradox exists in connection with languages and the learning of them. On the one hand, the ability to speak two or more languages reasonably well is prima facie evidence of better-than-average intelligence. On the other hand, learning a language is a very easy business. The proof of it is that every living human being who is not an utter idiot speaks one! -- The trick lies in how you go about it. It would seem reasonable to use somewhat the same system to learn a new language as you did to acquire your own. Tthis idea built upthe Berlitz Schools of Language from a one-room studio in Providence, Rhode Island, to a globe-circling institution with over 300 branches. -- In a word, you learn to speak a language by speaking it -- and in no other way. That is how Germans learn German, and that is how you learned English.
