We are basically not interested in which of the ethical theories is the best. It is believed that there are areas in which each theory complements others by how they differ.
Procedure for General Evaluation:
1. The theory must be clear and formulated with concepts that are coherent and applicable.
2. It must be internally consistent in that none of its tenets contradicts any other.
3. Neither the theory nor its defense can rely upon false information.
4. It must be sufficiently comprehensive to provide guidance in specific situations of interest to us.
5. It must be compatible with our most carefully considered moral convictions about concrete situations.
