 The agent-relative/agent-neutral distinction is widely and rightly regarded as a philosophically important one. Unfortunately, the distinction is often drawn in different and mutually incompatible ways. The agent-relative/agent-neutral distinction has historically been drawn three main ways: the ‘principle-based distinction’, the ‘reason-statement-based distinction’ and the ‘perspective-based distinction’. Each of these approaches has its own distinctive vices (Sections 1–3). However, a slightly modified version of the historically influential principle-based approach seems to avoid most if not all of these vices (Section 4). The distinction so understood differs from numerous other distinctions with which it might easily be confused (Section 5). Finally, the distinction so drawn is important to normative theorizing for a variety of reasons (Section 6).
