I like where this is going. If anyone interested in education and the learning process, I highly recommend the work of Alfie Kohn, a philosopher of education, (his work isn't formal and stuffy, it's quite accessible but I don't know what else to call him) particularly a collection of essays titled "What Does It Mean to Be Well Educated?" He deals with a wide variety of topics, and is critical of practices like standardized tests, homework, and negative as well as positive reinforcement. The mental clarity I feel after reading his work is similar to what I feel after reading one of PG's essays.
