 A second approach to the location of appropriate sites of collective responsibility has been to use groups such as ethnic communities, clubs, and social movements as paradigmatic cases of appropriate collective responsibility on the grounds that these groups have members who share interests or needs in common. Two assumptions prevail here. The first is that groups whose members share interests or needs in common show signs of group solidarity, which Joel Feinberg defines in this context as a matter of individuals taking a strong interest in each others’ interests (Feinberg 1968). The second is that groups that show signs of group solidarity understood in this way are capable of acting and intending in the sense relevant to collective responsibility, since while they are made up of individuals, they pursue projects together.
