 The convergence of reasons and causes in historical processes is helpful in this context, because historical causes are frequently the effect of deliberate human action (Davidson 1963). So specifying the reason for the action is simultaneously identifying a part of the cause of the consequences of the action. It is often justifiable to identify a concrete action as the cause of a particular event (a circumstance that was sufficient in the existing circumstances to bring about the outcome), and it is feasible to provide a convincing interpretation of the reasons that led the actor to carry out the action.
