"Harry Stottlemeier's Discovery" is the student book for the project in philosophical thinking described in SO 008 123-126. It offers a model of dialogue -- both of children with one another and of children with adults. The story is set among a classroom of children who begin to understand the basics of logical reasoning when Harry, who isn't paying attention in class, says that a comet is a planet because he remembers hearing that comets revolve around the sun just as planets do. The events that follow in the classroom and outside of school are a recreation of the ways that children might find themselves thinking and acting. The story is a teaching model; non-authoritarian, and anti-indoctrinating, it respects the value of inquiry and reasoning, encourages the development of alternative modes of thought and imagination, and suggests how children are able to learn from one another. Further, it sketches what it might be like to live and participate in a small community where children have their own interests, yet respect each other as people, and are capable at times of engaging in cooperative inquiry for no other reason than the satisfaction of doing so.
