 Harry Frankfurt’s comparison between a willing drug addict and an unwilling addict illustrates important features of his version of the structural approach to responsibility. Both of Frankfurt’s addicts have desires to take the drug to which they are addicted, and the nature of their addictions is such that both addicts will ultimately act to fulfill their first-order addictive desire. But suppose that both addicts are capable of taking higher-order perspectives on their first-order desires, and suppose that they take different higher-order perspectives. The willing addict endorses and identifies with his addictive desire. The unwilling addict, on the other hand, repudiates his addictive desire to such an extent that, when it ends up being effective, Frankfurt says that this addict is “helplessly violated by his own desires” (1971: 12). The willing addict has a kind of freedom that the unwilling addict lacks: they may both be bound to take the drug to which they are addicted, but insofar as the willing addict is moved by a desire that he endorses, he acts freely in a way that the unwilling addict does not (Frankfurt 1971: 19). A related conclusion about responsibility may be drawn: perhaps the unwilling addict’s desire is alien to him in such a way that his responsibility for acting on it is called into question (for a recent defense of this conclusion, see Sripada 2017).
