Practical Necessity and Moral Heroism
Discussions of closely associated notions of practical necessity, volitional necessity, and moral incapacity have profited from a focus on cases of agential crisis to further our understanding of how features of an agent’s character might bind her. This paper turns to agents in crises in order to connect this way of being bound to the phenomenon of moral heroism. The connection is fruitful in both directions. Importing practical necessity into examinations of moral heroism can explain the special sense of bindingness moral heroes frequently express while preserving the status of heroic acts as supererogatory. It also helps explain how heroes persevere and act as so few others do. On the other hand, the context of moral heroism allows a fuller development of some features of the concept of practical necessity, shedding more illuminating light on the roots of practical necessity in character through recent findings in the psychology of moral exemplars.
