Episode 82 - Speaking in Tongues

This is a theme with me -- the pros and cons (there aren't many cons) of learning foreign languages. Also, how does it actually work? Why is one language easier for a given person to learn than another? Also, what's the relatiion between learning a language to read, and learning a language to speak? And why is psychology so important, personal psychology, in the acquisition of a foreign 'tongue'? Here is 50 years' experience of pain and suffering (and altered states) rolled up into a single half hour.
