Ethical Egoism and Ethical Subjectivism
Ethical Egoism is the normative ethical position that moral agents ought to do what is in their own best self interest.
There are 3 different forms of ethical egoism: individual, personal and universal. An individual ethical egoist would think that all people should do whatever benefits them, a personal ethical egoist would say that he or she should act in his or her own self-interest, but would make no claims about what anyone else ought to do, a universal ethical egoist would argue that everyone should act in ways that are in their own interest
Ethical Subjectivism claims that 1. ethical sentences express propositions 2. some such propositions are true 3. Those propositions are about the attitudes of people.
Ethical Subjectivism extends what people and groups believe to be true into what really is true.
