I spent a couple of hours to make it, which means I corrected some typos and added a little consistency to the formatting, but it isn't perfect. My opinions throughout are also inconsistent because I wrote the notes within a kind of stream of consciousness. I changed my opinion based on the readings. I updated this book on 6/24/2011 and rewrote most of the introduction using my newer notes on the meaning and nature of meta-ethics. If you are interested in Metaethics, I recommend reading Moral Realism and the Foundations of Ethics by David Brink. The Stanford Encyclopedia of Philosophy is also a helpful resource at http://plato.stanford.edu. Here are some links to specific articles
