 Frank Hindriks takes on this challenge in “The Duty to Join Forces: When Individuals Lack Control” (Hindriks, 2019) and elsewhere (Blomberg and Hindriks, 2020). Hindriks argues very persuasively that we can create the required organized collective if we can substantiate a duty on the part of the individual moral agents to join forces: to approach others, to convince them to contribute to the joint efforts, and to become part of a collective action. This duty is initially associated with individual moral agents. But, Hindriks claims, since it focuses on mobilizing others rather than on preventing harm per se, it is “irreducibly collective” (Hindriks, p. 204).
