Time to start a thread devoted to this subject! Critical thinking is no longer taught in school, and the 7 liberal arts are not longer part of a liberal arts degree in college, so we must all be self-taught. What I'm interested in discussing is the 7 liberal arts, liberal meaning a free man not political leaning. These are made up of the Trivium (Grammar, Logic, Rhetoric) and Quadrivium (Math, Music, Geometry, Astronomy). I think Logical Fallicies fits with this topic but is so big it may deserve is own thread.
