 The problem of demarcation also plagues the paradigm case of supererogatory behavior, the so-called saintly and heroic acts. Fire fighters rushing to a burning house to save its residents risk their lives in a way that moves every spectator. But are they not paid for it? Is it not “their job”? Are they not justified when in a later response to a journalist’s question they insist that they only did their duty? The supererogationist might respond by turning our attention to a similar risk taken by a by-stander who joins the professional emergency forces and literally jumps into the fire. Deniers of supererogation might argue that although such an action is heroic, it ought not to have been performed, since the slight chances of saving the victims of the fire do not justify the very high risk of loss of life of the volunteer. Kant at one point expresses his doubts about the moral motive behind some of the extreme cases of moral heroism and warns against moral fanaticism and sentimentalism (Kant 1949).
