 The common good belongs to a family of concepts that relate to goodness rather than rightness (Sidgwick 1874). What makes the common good different from other concepts in this family is that it is a notion of the good that is understood to be internal to the requirements of a social relationship. In any community, the common good consists of the facilities and interests that members have a special obligation to care about in virtue of the fact that they stand in a certain relationship with one another. In a family, for instance, the family home is part of the common good because the familial bond requires members to take care of the home as part of a shared effort to care for one another’s interests in shelter and safety. In a university, the climate of academic freedom on campus is part of the common good because the special relationship among members of the university community requires them to care for this climate as part of a shared effort to care for one another’s interests in teaching, learning and inquiring.
