This Introduction tells the story of intergerational justice and how it has influenced philosophers and political thinkers throughout history. The Introduction goes on to discuss the aims of the book, which is to offer a sustained discussion of intergenerational justice as seen by practical philosophers. The first part of the book focuses on the way in which various schools of thought in moral and political philosophy approach the domain of intergenerational justice, while the second part focuses on more specific aspects, such as how these theories address the question of motivation, how they deal with demographic fluctuations, or how they can be applied to real-world issues such as climate change.

This paper provides a comparative analysis of the way in which, as well as the extent to which, two key variables potentially allow for the development of more left-wing versions of libertarianism and hobbesianism. It turns out that hobbesianism, while disposing of ways to extend the scope of what should be seen as the “cooperative surplus”, is in trouble when it comes to justifying “equal division” as a general rule to divide up such a surplus. In contrast, libertarianism can meaningfully rely on strategies extending the notion of external resources as well as on an equal division rule. We then explore what this entails with respect to the capacity of such theories to offer more redistributive versions than their standard forms. We also briefly look at how to map such left-wing versions, and especially left-libertarianism, once they are compared with other theories such as luck egalitarianism or sufficientarianism.
