As I've spent the past few days researching language acquisition, I've come across promising theories. That's not the main point though, what I intend to communicate is that the search and development of anti-dogmatic knowledge are possibly one of the most powerful things one can do.
This also brings me to the aspect of modern schooling. Modern classes, if I remember correctly, are heavily based on textbook information - a static, medium, often vague, as Peat has put it, of information.
From my own experience, a better starting point to learn is encyclopedias, though they can still be dogmatic, they are probably a better choice. Then, research the citations/primary literature in the encyclopedia and then ask questions that arise.
