Hi folks! Been a LessWrong lurker for a while. Here's a little project I'm excited about, which has been useful in organizing my thoughts on meta-ethics.
This piece is a walk-through of an original flowchart (made with lots of help from friends) that categorizes the major meta-ethical positions. It lays out the points where different meta-ethical theories diverge and gives a brief intro to each major theory. I think it's a nice tool for getting a sense of the broadest strokes of academic meta-ethics, and being able to hold the different theories in your head.
