I want to construct an ethics system, my ethics. When I studied logic was very fruitful to understand the theory of the theory of logic (meta-theory). Now I want to learn about ethics because I want to construct my ethics, so I must know what I am going to construct and I know that a meta-theory of ethics could help me. Can someone please provide some references?
One book that is not just one ethics but actually "meta-ethics" is Christine Korsgaard's Sources of Normativity. It goes over the different types of justifications given for different moral theories and ultimately she gives a Kantian defense. It covers moral realism, voluntarism, and constructionist views. Not sure about what anti-realism is so dont think thats in there, but the book was written in the 90's so...yea.
