Ethical Theory, Completeness & Consistency

  • Andrew Moore


This paper argues that many leading ethical theories are incomplete, in that they fail to account for both right and wrong. It also argues that some leading ethical theories are inconsistent, in that they allow that an act can be both right and wrong. The paper also considers responses on behalf of the target theories.
