Hi Paul. Ethical theory refers to the study of ethics generally. Meta-ethics is the study of the nature of ethics. For example, what makes an ethical or moral act ethical or moral? Or, what is the nature of the good life? Those kinds of questions. Normative ethics concerns not the nature or content of ethics generally or even specifically in the case of actions, but rather how we ought to live in order to be ethical or moral.
If you'll forgive a naive question; is "ethical theory" the same as "metaethics"?
