Self-effacing ethical theories are those that recommend their own erasure. Such theories are a controversial topic in contemporary moral philosophy. In this thesis, I shed light on what is and is not wrong with this type of theory. I examine two kinds of self-effacing ethical theories, a radical version of sophisticated consequentialism and developmental virtue ethics. I defend them against three common objections to self-effacing theories. I raise and develop two novel objections to self-effacing theories: a self-erasure objection and an (...) incompleteness objection. I conclude by arguing that these two objections pose fewer challenges for developmental virtue ethics than radical sophisticated consequentialism. (shrink)
