Some of this I've thought about before, the famous 'you can never know everything and part of what you know is always wrong' line has always struck a chord for me and I'd even say had a significant influence on my thinking on real-world issues as well. But this goes a lot deeper and further than that, very interesting read.
One typing error I noticed: near the end you refer to Tallanvor's leadership of the Band in Mat's absence, which should have been Talmanes, as Tallanvor is Morgase's dedicated guard officer.
