This chapter begins by offering a nuanced account of agency, and of its practical operation, at the corporate level. It then explores and seeks to justify the notion of corporate character, as operating in a similar manner to the way that character does within the lives of individuals, and hence of its singular importance if the potential for the good purpose of the firm is to be realized. Turning to the purpose of the firm, a MacIntyrean correction to the Aristotelian–Thomistic tradition as incorporated in Catholic Social Teaching is suggested. This revised understanding gives as much weight to the goods produced or services provided as it does to the intrinsic value of the work undertaken by practitioners. In sum, this chapter gives a rounded account of the characteristics and role of the firm and hence of its potential to contribute to the common good.
