Locked Room Free Will

The scenario

A man is carried, while sleeping, into a room where someone he has long wanted to meet is present. The door is locked from the outside without his knowledge. He wakes, sees his friend, and decides to stay. He stays voluntarily, for his own reasons, because he genuinely wants to.

He couldn't have left. But he didn't want to leave.

Locke's question: is this man free? His will is unconstrained. His action matches his desire. But the space of possibilities he believes himself to occupy is not the space he actually occupies.

What Locke was drawing out

Locke used this case to distinguish two different things we might mean by freedom. Freedom of will is about whether your desires and intentions are your own, not externally coerced. Freedom of action is about whether the world lets you do what you will.

The man in the locked room has the first but lacks the second. His will is free. His action is not, though it doesn't feel that way to him.

This maps onto a broader compatibilist picture. Compatibilists tend to say that what matters for moral freedom is freedom of will: that your actions flow from your own desires and reasoning, without direct coercion or manipulation. The locked room seems to support this, since we'd be reluctant to say the man is unfree in any morally relevant sense, given that he would have stayed anyway.

But Locke wasn't straightforwardly endorsing compatibilism. He was mapping the terrain: willing and acting are different, and freedom attaches to each in different ways.

What ignorance of constraint changes

The harder question is whether it matters morally that the man doesn't know the door is locked.

From outside, the situation looks like a clear case of constrained action. He can't leave. From inside, it looks like unconstrained choice. His experience of freedom is intact. His actual freedom is not.

This asymmetry becomes uncomfortable when you expand the frame. If a society's structure forecloses certain options without people knowing those options were ever available, and if those people would have chosen the same paths anyway, are they free? The locked room suggests you can feel free while not being free, and that the feeling is not irrelevant, but also not decisive.

What the case doesn't settle is what we should care about most. If the man never discovers the door was locked, and he's happy, has he been wronged? Most people's intuitions say yes, though articulating exactly why requires specifying what freedom is for.
