Meaning and Value Across the Generations

This chapter argues that our relations to our successors are richer, more varied, and more complex than is sometimes recognized. Although we cannot in any straightforward sense interact or form personal relationships with people who will live long after we have died, future generations nevertheless matter greatly to us and in a variety of ways. These facts, which reflect our underappreciated historicist sensibility, must be taken into account in developing an adequate theory of intergenerational ethics. They are also facts of great motivational significance. To ensure the survival of humanity, sufficient numbers of people must be strongly and stably motivated to solve the problems that threaten future generations, and people’s sense of moral obligation may not, by itself, be sufficiently robust or reliable to provide all the necessary motivational support. So one challenge we face, in seeking to address problems like climate change and nuclear proliferation, is to overcome this potentially disabling motivational deficit. Yet once one appreciates the complexity of our attitudes toward future generations, one can see that we have a variety of reasons for caring about the fate of our successors. These reasons provide additional motivational resources that may complement and cooperate with our distinctively moral motivations for addressing threats to future generations.
