Formal vs. real vs. plain ol' learning. Isn't it really all the same? Any source whether book, web or teacher can be wrong. Maybe the real learning begins when a student is able to get past taking everything as gospel from an "authority".

The gist of my question was more along the lines of how effective is CBT compared to having a live teacher, but i am now thinking that's pretty moot. There are all sorts of different styles of learning and it may even depend on what's being taught.
