@Ennui phil,
"Yes we must discard ideas, for there are millions of ideas and they siimply confuse and coomote us and at times they disillusion us."
"Books should be chosen in a way that keeps us clear of nets of things or out of boxes of prejudices and biases. We are normally programmed and are wired to certain patterns of thinking and we must de-pattern our thinking proccesses."
I think you have, in a way, responded to your own question. What books, or education, for that matter, achieves in our lives is 1) presenting other ways of thinking and living for our consideration, and 2) helping us transcend the given around us by both encouraging questions that might never have been asked, as well as providing the means and tools to "depattern" the process by showing us different patterns and "wrong" patterns.
The peasant farmer may well share our wonder at the meaning of life, but without the experience of differing perspectives, will end up worshipping some god dwelling in the local spring or sacrificing another human being for a good harvest.
