I've decided to release my notes on Rambam's understanding of the story of Man in the Garden of Eden. (Note: it's not as polished as my usual writing.) It's valuable not only in terms of understanding Rambam's view of this topic, and how he approached it in a thoroughly non-literal manner, but also for how to approach the Guide to the Perplexed in general. When reading the notes, observe how it is only possible to deduce Rambam's view by studying his comments in several different parts of the Guide, and analyzing how they shed light on each other. (This is similar to how the subject of his comments about the mistaken belief in the sounds of the spheres only becomes clear in a different place in the Guide.) Note too how Greco-Muslim philosophy provides the framework for Rambam's discussion.
