If we could just get kids to read these story books that taught you to question everything , and think logically about everything. teaching one why one thing is a fallacy every chapter. just imagine the impact this could have on an entire generation of critical thinkers.
Probably wouldnt make much of a difference. Most people I've met who've studied philosophy and religions usually just end up thinking too much of themselves. It's not like reading Nietzsche makes you an original thinker or anything, it mostly just gives you the illusion that you are.
The trouble with teaching critical thinking is making it relevant to the student. Deconstructing emotion-laden belief systems is only useful to create an antagonistic relationship. Principles and techniques and underlying epistemology can be taught effectively, but so much of effective critical thinking comes from experiential learning and the passage of time. Mentalists and magicians had a real knack for this, more than most professional educators in my opinion.
