In this article, we explore the implications of a Rawlsian theory for intergenerational issues. First, we confront Rawls's way of locating his `just savings' principle in his Theory of Justice with an alternative way of doing so. We argue that both sides of his intergenerational principle, as they apply to the accumulation phase and the steady-state stage, can be dealt with on the bases, respectively, of the principle of equal liberty (and its priority) and of the difference principle. We then proceed by focusing on the implications of applying maximin to his steady-state stage. One central claim is that, in principle, Rawlsians should consider not only generational dissavings, but also generational savings, as unfair. This principle suffers a series of exceptions on which we focus in the fourth section of the article. In some cases, growth can be maximin compatible.

The first debate in this article has to do with the very possibility of intergenerational justice beyond our obligations towards members of other generations while they coexist with us. Here, we ask ourselves whether we owe anything to people who either have died already, or are not yet born. Differences in temporal location mean that people may not exist at the same time — be it only during part of their life — which raises special ethical challenges. It is one thing to decide whether we owe anything to the next generation(s). It is another to define what we owe them. Most standard theories of justice have tried to answer this difficult question. This article focuses on a comparison between a reciprocity-based and an egalitarian account of justice between generations. It then turns, on the one hand, to a brief discussion of alternative theories and, on the other hand, to implementation issues.
