To argue for the pessimism that free will is impossible in a deterministic world, a powerful way has been to invoke a case in which a behavior has a cause that is intuitively excusing and the cause is deterministic, beyond the agent’s control, and opaque to the agent. The pessimist then argues: '(i) The agent in such a case is not fully responsible for the behavior. And (ii) if our world is deterministic, every behavior in it must also have a cause with the above characteristics. Therefore, we could not be fully responsible for our behavior in a deterministic world.' I do not dispute premises (i) and (ii) but contend that the conclusion does not follow. For if the behavior is right, the agent can be free in it and fully responsible for it e...
