 Réaume’s own proposal (1988, 1994), which has attracted much attention amongst commentators on group rights, is that we should understand group rights as rights to “participatory goods”. A participatory good is a public good of a particular type. It is a good whose enjoyment by an individual depends upon its also being enjoyed by others. Consider the case of clean air again. Although this is typically a good that is public to a group, each individual breathes in and out as an individual and enjoys the good of clean air as an individual. The goodness of clean air for me does not depend upon its also being good for you, even though it is good for you. Now consider goods such as friendship, a team game, and a convivial party (Réaume 1988, 12–13; Waldron 1993, 355–6). Those are necessarily social goods. I cannot enjoy genuine friendship as an entirely individual good; I can play a team game only if others do too; and I can take pleasure in conviviality only as a shared experience. So some goods are necessarily “participatory” in nature. These goods have also been described as “communal” (Waldron 1993, 339–69), “shared” (Green 1988 207–9; Raz 1995, 35–6), and “common” (Marmor 2001). Charles Taylor’s notion of “irreducibly social goods” has been deployed to similar effect: if those goods are the objects of rights, their irreducibly social character implies that they must be the objects of group rights (Taylor 1995, 127–145; Sheehy 2006, 159–167, 175–195).
