Even though the free will debate is not a recent phenomenon, there are still many opposing camps who cannot find common ground. Elbow Room by Dennett supports the claim of the existence of free will (even when determinism is true), and remains highly valuable for the current debate. In his book, Dennett advocates for free will that includes control and moral responsibility, based in human rationality and error. This thesis tries to challenge Dennett’s idea of free will as ‘elbow room’ with the incompatibilist arguments of Pereboom, who is known for his quarantine argument and rejecting moral responsibility.
