 We can easily grant that Black has the power to directly manipulate Jones’ body so Jones loses the ability to move his body in any way other than the ways that Black wants. We might even grant that Black has the power to directly manipulate Jones’ mind/brain, so Jones loses the ability to “move” his mind in any way other than the ways that Black wants. But Black never exercises his power. There is a difference between the existence of a power and the exercise of a power. It is a modal fallacy to reason from “Black has the power to bring it about that Jones lacks the ability to do otherwise” to “Jones lacks the ability to do otherwise”. The truth about Jones is not that Black robs him of the ability to do otherwise; it is the more complicated truth that Black puts him at constant risk of losing the ability to do otherwise. Jones’ free will and his moral responsibility are dependent on the luck of his deliberations and intentions co-coinciding with those of Black (Vihvelin 2013; for some other criticisms of Frankfurt’s argument see Lamb 1993, Alvarez 2009, and Steward 2009).
