Abstract
In Michael Moore's important book Causation and Responsibility, he holds that causal contribution matters to responsibility independently of its relevance to action. We are responsible for our actions, according to Moore, because where there is action, we typically also find the kind of causal contribution that is crucial for responsibility. But it is causation, and not action, that bears the normative weight. This paper assesses this claim and argues that Moore's reasons for it are unconvincing. It is suggested that sometimes a person's responsibility for that to which he causally contributes depends on his recognition of an identity between himself and the protagonist of the event for which he is held responsible. Since this fact about identity is not captured by causal contribution, action matters to responsibility for reasons that are not exhausted by the fact that action involves causal contribution. The relevance of this idea for accomplice liability is also briefly discussed
