This document discusses theories of the mind and metaphors of memory. It covers Descartes' mind-body dualism theory, behaviorism which views the mind as a "black box", and modern cognitive science which integrates concepts from multiple disciplines. Metaphors of memory discussed include the memory as a muscle, slate, library, and network of concepts and relationships. The document also discusses generalizing information through induction, hypermedia being analogous to inductive thinking, deducing implications from existing knowledge through logic, and using spreadsheets to teach logical data manipulation. It concludes with discussing meta-cognition as thinking about one's own thinking processes.
