 It might be responded that, although a fact cannot be a reason that explains one’s action unless the person is aware of it, it does not follow that the explanation of the action must mention their awareness of the reason. For instance, we can explain why Jess went to the hospital by citing her reason for going, namely that her father had been admitted to the intensive care unit—this points to something she saw in the action that made it desirable: e.g., that she could then be with her father in this difficult moment. The explanation does not need to mention any psychological fact, such as the fact that she knew that her father had been admitted, even though the explanation presupposes this fact. Against this suggestion, a defender of psychologism for explanatory reasons might urge that these explanations are elliptical and when fully spelled out their explanans (the part of the explanation that does the explaining) contains facts about what she knew or believed. But are these explanations really elliptical? It seems undeniable that a person cannot act for the reason that p, or on the grounds that p, unless she stands in some epistemic relation to p: she needs to believe, know, accept, etc. that p. However, it does not follow that all full rationalisations need mention psychological facts and that, when they don’t, this is because they’ve been given in elliptical form. Perhaps the fact that the agent knows the relevant things is simply a necessary condition for her reason to be the explanans in a reason explanation. Or as Dancy suggests, her knowing or believing may be an “enabling condition” for the explanation (Dancy 2000: 127).
