Abstract
Transgenerational social actions are collective actions that endure over a considerable period of time and require the cooperation of multiple generations. Yet, it remains unclear what kind of obligations and rights, if any, allow actions to persist through the ages, binding future generations to be part of them. This paper proposes a way forward by considering transgenerational actions as a particular type of long-term joint commitments. Drawing on plural subject theory, I explore the conditions for membership, normativity, and justification of transgenerational joint commitments, while also amending the model to address classical issues of asymmetry, non-existence, and non-reciprocity of future generations. The proposed approach meets three desiderata: transgenerational actions do not rely on individual intentions but are collective in a strong sense, they are normative in a social sense but can encourage the development of a personal moral sensitivity to transgenerationality, and they are both stable over time and flexible enough to resist paternalism through the proxy acts of representatives of future generations.
