ABSTRACT
Blackburn’s projectivism is antirealist because it does not rely on a commitment to moral properties or moral facts. Its explanations of moral phenomena seek to explain ethical activity “from the inside out-from the naturally explicable attitudes to the forms of speech that communicate them, challenge them, refine them, and abandon them.” Blackburn finds support for his naturalistic projectivism about ethics in the writings of Hume and Wittgenstein. His projectivism seeks to avoid difficult problems arising from the need for an ontology of morals.
