Any adequate political theory must provide a plausible account of our obligations to future generations. It must also derive those obligations from morally significant features of our relationship to those who will live in the future, not from contingent accidents of human biology. The Minimal Test outlined in this paper offers a simple way to assess whether political theories are able to meet this challenge. It appears that several popular contemporary political theories will have difficulty passing that test

Many themes of late twentieth century ethics are prefigured in Sidgwick’s Method of Ethics. In particular, Sidgwick’s ‘Dualism of Practical Reason’ sets the scene for current debates over the demands of morality. Many philosophers agree that Sidgwick uncovers a deep and troubling conflict at the heart of utilitarian ethics. But Sidgwick’s own response to that conflict is treated, not as a live philosophical option, but as a historical oddity. In the twenty-first century, few philosophers see the intimate connection between the dualism of practical reason and the investigation of psychic phenomena that played such a large role in Sidgwick’s life. The aim of this paper is to investigate Sidgwick’s own approach to the dualism of practical reason. Its general conclusion is that a non-dualistic morality demands less than a theistic religion, contrary to what Sidgwick worried - especially as concerns personal immortality and freedom

What do we owe to our descendants? How do we balance their needs against our own? Tim Mulgan develops a new theory of our obligations to future generations, based on a new rule-consequentialist account of the morality of individual reproduction. He also brings together several different contemporary philosophical discussions, including the demands of morality and international justice. His aim is to produce a coherent, intuitively plausible moral theory that is not unreasonably demanding, even when extended to cover future people. While the book focuses on developing this new account, there are also substantial discussions of alternative views, especially contract-based accounts of intergenerational justice and competing forms of consequentialism.
