The article discusses Michael Slote's Satisficing Consequentialism, which is the view that moral agents are not required to maximise the good, but merely to produce a sufficient amount of good. It is argued that Satisficing Consequentialism is not an acceptable alternative to Maximising Consequentialism. In particular, it is argued that Satisficing Consequentialism cannot be less demanding in practice than Maximising Consequentialism without also endorsing a wide range of clearly unacceptable actions. It is then argued that Slote's inability to provide adequate reasons for moral satisficing stems from a mistaken analogy between rationality and morals. The sense of 'good enough' which is relevant to morality is one which focusses on the effort an agent puts in, rather than on the outcome she produces. However, replacing outcomes with efforts would undermine Slote's Consequentialist project. Finally, it is suggested that similar problems will be faced by others who seek to construct essentially Consequentialist theories which are not unduly demanding.

A basic feature of liberal political philosophy is its commitment to religious neut‐rality. Contemporary philosophical discussion of intergenerational justice violates this com‐mitment, as it proceeds on the basis of controversial metaphysical assumptions. The Contractualist notion of a power imbalance between generations and Derek Parfit’s non‐identity claims both presuppose that humans are not reborn. Yet belief in rebirth underlies Hindu and Buddhist traditions espoused by millions throughout the world. These traditions clearly constitute what John Rawls dubs “reasonable comprehensive doctrines”, and therefore cannot be dismissed by political liberals. In many societies, including the USA, the UK, and India, belief in rebirth exists alongside other traditions, as well as modern Western views. A liberal theory for such societies must be impartial regarding rebirth, and the after‐life in general. Two alternatives forms of liberal neutrality are sketched, based on Contractualism and Consequentialism.

Imagine living in the future in a world already damaged by humankind, a world where resources are insufficient to meet everyone's basic needs and where a chaotic climate makes life precarious. Then imagine looking back into the past, back to our own time and assessing the ethics of the early twenty-first century. "Ethics for a Broken World" imagines how the future might judge us and how living in a time of global environmental degradation might utterly reshape the politics and ethics of the future. This book is presented as a series of history of philosophy lectures given in the future, studying the classic texts from a past age of affluence, our own time. The central ethical questions of our time are shown to look very different from the perspective of a ruined world. The aim of "Ethics for a Broken" World is to look at our present with the benefit of hindsight - to reimagine contemporary philosophy in an historical context - and to highlight the contingency of our own moral and political ideals.

Total utilitarianism implies Parfit's repugnant conclusion. For any world containing ten billion very happy people, there is a better world where a vast number of people have lives barely worth living. One common response is to claim that life in Parfit's Z is better than he suggests, and thus that his conclusion is not repugnant. This paper shows that this strategy cannot succeeed. Total utilitarianism also implies a reverse repugnant conclusion. For any world where ten billion people have lives of excruciating agony, there is a worse world where a vast number of people have lives almost worth living. This reverse repugnant conclusion is at least as repugnant as Parfit's original. If we avoid the latter by raising the zero level, then the former becomes more repugnant. We cannot save total utilitarianism by tinkering with the zero level

Utilitarians must think collectively about the future because many contemporary moral issues require collective responses to avoid possible future harms. But current rule utilitarianism does not accommodate the distant future. Drawing on my recent books Future People and Ethics for a Broken World, I defend a new utilitarianism whose central ethical question is: What moral code should we teach the next generation? This new theory honours utilitarianism’s past and provides the flexibility to adapt to the full range of credible futures – from futures broken by climate change to the digital, virtual and predictable futures produced by various possible technologies.

Utilitarianism - a philosophy based on the principle of the greatest happiness for the greatest number of people - has been hugely influential over the past two centuries. Beyond ethics or morality, utilitarian assumptions and arguments abound in modern economic and political life, especially in public policy. An understanding of utilitarianism is indeed essential to any understanding of contemporary society. "Understanding Utilitarianism" presents utilitarianism very much as a living tradition. The book begins with a summary of the classical utilitarianism of the eighteenth and nineteenth centuries. Subsequent chapters trace the development of the central themes of utilitarian thought over the twentieth century, covering such questions as: What is happiness? Is happiness the only valuable thing? Is utilitarianism about acts or rules or institutions? Is utilitarianism unjust, or implausibly demanding, or impractical? and Where might utilitarianism go in the future?
