The Rights of Future Persons and the Ontology of Time

Many are committed to the idea that the present generation has obligations to future generations, for example, obligations to preserve the environment and certain natural resources for those generations. However, some philosophers want to explain why we have these obligations in terms of correlative rights that future persons have against persons in the present. Attributing such rights to future persons is controversial, for there seem to be compelling arguments against the position. According to the “nonexistence” argument, future persons cannot have rights (and so should not be attributed rights) because they do not exist. According to the “no-satisfaction” argument, future persons cannot have a right to resources that do not exist at the time of their existence because such a right could not, in principle, be satisfied. In this paper, I will argue that an eternalist ontology of time provides the resources for satisfactorily responding to both the nonexistence and the no-satisfaction arguments.
