 Locke says the man remains in the room voluntarily, even if he is not free to leave. If the man is responsible for staying, this is a counterexample to PAP. Like the previous example, this one also appears to follow Frankfurt’s recipe. What makes the man’s staying in the room unavoidable—namely, the room’s being locked—plays no role in his staying: he remains willingly, for his own reasons (see Zimmerman 1988: 120–6 for a similar example).
