When do your beliefs become knowledge?

I've been reading a lot of philosophy lately -- Kierkegaard and Dawkins, Lewis, Hume, Calvin and Augustine, you name it -- for a class I'm taking, as well as for my own enjoyment. One of the interesting things about philosophy is that it's a discipline that takes the understanding of understanding seriously. As a teacher, that's fascinating to me; has education -- specifically, the way we in 2009 are trying to educate -- really examined what knowledge is? Have educational systems considered what the wealth of literature says about knowledge, and responded to it responsibly? http://ping.fm/uOeNB
