 In the metaethical debate, there is widespread disagreement about the possibility of providing an external foundation for ethics—“external” in the sense of being external to ethical beliefs—and the same disagreement is found amongst deontologists and utilitarians. Some believe that their normative ethics can be placed on a secure basis, resistant to any form of scepticism, such as what anyone rationally desires, or would accept or agree on, regardless of their ethical outlook; others that it cannot.
