V—Why Externalism is not a Problem for Ethical Intuitionists

Ethical intuitionists are often criticized on the ground that their view makes it possible for an agent to believe that she ought to Φ whilst lacking any motive to Φ - that is, on the ground that it involves, or implies a form of externalism. I begin by distinguishing this form of externalism (what I call belief externalism) from two other forms of ethical externalism - moral externalism and reasons externalism. I then consider various reasons why one might think that ethical intuitionism is defective in so far as it involves, or implies belief externalism, and argue that these objections are unpersuasive
