Abstract
The mentalistic orthodoxy about reason-explanations of action in the philosophy of mind has recently come under renewed attack. Julia Tanney is among those who have critiqued mentalism. The alternative account of the folk practice of giving reason-explanations of actions she has provided affords features of an agent’s external environment a privileged role in explaining the intentional behaviour of agents. The authors defend the mentalistic orthodoxy from Tanney’s criticisms, arguing that Tanney fails to provide a philosophically satisfying or psychologically realistic account of reason-explanation of action.
