The amount of thought that can go into teaching eight 10-to-12 year olds for an hour is mind-boggling, as is the fact that the way you handle even the simplest of the things that come up with them comes down to philosophy. Not developmental psychology, not pedagogic principles, not accumulated experience, not even blind faith — it comes down to what you think life is all about. Where do we come from? What is the essence of a good life? And why ever did we find ourselves here in the first place, anyway?
