Also (as I tried to post last night but got crashed on), you learn through experience, not through reason. Reason and logic are tools for learning from experience.

Librarians, for instance, learned years and years ago that you can teach research techniques 'til the cows come home, but the teaching won't "take" until it becomes essential for writing a paper or something -- that is, until experience requires it. Military types know that all the training in the world won't stick until the first time a bullet goes "crack!" past your ear. Medicine's old teaching tenet of "See one, do one, teach one" has quite a bit to recommend it.
