Combines "hard" logic and supposedly "soft" ethics in order to formulate ethical principles more clearly, to organize them into a defensible system , and to help us think more rationally about morality.

This is designed to help students who have already done an introductory course in philosophy - guiding them to think more clearly about how to form their moral beliefs in the wisest and most rational way.
