 The distinction between internal and external motivations allows identification theorists to enrich classical compatibilists’ understanding of constraint, while remaining compatibilists about free will and determinism. According to classical compatibilists, the only kind of constraint is external (e.g., broken cars and broken legs), but addictions and phobias seem just as threatening to free will. Identification theorists have the resources to concede that some constraints are internal. For example, they can argue that our agoraphobic Luke is not free in refraining from going outside even though this decision was caused by his strongest desires because he is not identified with his strongest desires. On compatibilist identification accounts, what matters for self-determination is not whether our actions are determined or undetermined, but whether they are brought about by motives with which the agent is identified: exercises of the power of self-determination consists in an agent’s actions being brought about, in part, by an agent’s motives with which she is identified. (It is important to note that while we have distinguished reasons-responsive accounts from identification accounts, there is nothing preventing one from combing both elements in a complete analysis of free will.)
