 Another influential trend in compatibilism has been to argue that moral responsibility does not require an ability to do otherwise. If this is right, then determinism would not threaten responsibility by ruling out access to behavioral alternatives (though determinism might threaten responsibility in other ways: see van Inwagen 1983: 182–88 and Fischer &amp; Ravizza 1998: 151–168). In a very influential 1969 paper, Harry Frankfurt offers examples meant to show that an agent can be morally responsible for an action even if he could not have done otherwise. Versions of these examples are often called Frankfurt cases or Frankfurt examples. In the basic form of the example, an agent, Jones, considers a certain action. Another agent, Black, would like to see Jones perform this action and, if necessary, Black can make Jones perform it through some type of intervention in Jones’s deliberative process. However, as things transpire, Black does not intervene in Jones’s decision making since he can see that Jones will perform the action on his own and for his own reasons. Black does not intervene to ensure Jones’s action, but he could have, and he would have, had Jones showed some sign that he would not perform the action on his own. Therefore, Jones could not have done otherwise, yet he seems responsible for his behavior. After all, given Black’s non-intervention, Jones’s action is a perfectly ordinary bit of voluntary behavior.
