When you consider it—these are all rather basic matters of study, as such things go. A quick introduction to all of them (well, except naturalistic metaethics) would be... a four-credit undergraduate course with no prerequisites?

I wonder what it would take to make and run a MOOC? I know that MOOC software has been open sourced (e.g. OpenMOOC, edX). If a single undergrad course could have that big an impact on the world, isn't it worth doing?
