In our everyday moral judgments, we typically do not suppose that actions result from deterministic causal processes that trace back to factors beyond their agent’s control. Our ordinary intuitions do not presuppose that causal determinism is true, and they could indeed it is false. The incompatibilist's claim is that if we did assume determinism and internalize its implications, our judgments about moral responsibility might well be different from what they are. Spinoza remarks, "experience itself, no less than reason, teaches that men believe themselves free because they are conscious of their own actions, and ignorant of the causes by which they are determined".
