 A broad justification such as this leaves unstated what associations might be constitutive of human flourishing. Perhaps there is no definitive list. But most would include friendships, familial relationships, and some of the social institutions that foster, sustain, and secure the social life in which we engage as part of our flourishing. To the extent that we accept that engagement with or in a particular form of association or relation is constitutive of our flourishing, to that extent we will consider loyalty to it to be justified—even required.
