Our everyday notions of responsibility are often driven by our need to justify ourselves to specific others – especially those we harm, wrong, or otherwise affect. One challenge for contemporary ethics is to extend this interpersonal urgency to our relations with those future people who are harmed or affected by our actions. In this article, I explore our responsibility for climate change by imagining a possible ‘broken future’, damaged by the carbon emissions of previous generations, and then asking what its inhabitants might think of our current behaviour, our moral thinking, and our excuses. In particular, I will focus on a simplified scenario where present people can only avoid a broken future by sacrificing Rawlsian favourable conditions. Suppose we refuse to avoid a broken future, on the grounds that we cannot be expected to make such great sacrifices. If the broken future lacks favourable conditions, will its inhabitants accept our excuses? Will they hold us responsible for things we regard as excusable? If so, should we be guided by their judgements or by our own?

A common objection to _act consequentialism (AC) is that it makes unreasonable demands on moral agents. _Rule consequentialism (RC) is often presented as a less demanding alternative. It is argued that this alleged virtue of RC is false, as RC will not be any less demanding in practice than AC. It is then demonstrated that RC has an additional (hitherto unnoticed) vice, as it relies upon the undefended simplifying assumption that the best possible consequences would arise in a society in which everyone followed the same rules. Once this "_homogeneity assumption" is rejected, RC is unable to provide a workable alternative to AC

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?

In this article the editor of the Philosophical Quarterly briefly outlines the editorial process at that journal; explains why it is foolhardy to attempt to predict the future of philosophy; and, finally, attempts such a prediction. Drawing on his recent book Ethics for a Broken World, he argues that climate change, or some other disaster, may lead to a broken world where the optimistic assumptions underlying contemporary philosophy no longer apply. He argues that the possibility of a broken world has deep and unexpected implications for philosophy

Il cambiamento climatico presenta caratteristiche inedite che mettono in di- scussione il pensiero morale cui siamo abituati. In questo saggio, si rico- struiscono le modifiche che sarebbero necessarie per pensare le questioni morali poste dalla prospettiva di un mondo che subisca gli effetti del cam- biamento climatico: si potrebbe trattare di un mondo in frantumi, dove non ci sono più le condizioni minime di benessere, e le nozioni cui siamo abi- tuati – come certi diritti o l'ideale dell'eguaglianza – non valgono più e debbono venire sostituite da una nuova etica, che non potrà più affidarsi a intuizioni morali, per quanto solide e radicate.Climate change has new features that challenge our standard ethical thought. In this paper, the changes that are needed to deal with the moral is- sues raised in a world affected by the consequences of climate change are outlined. A climate-change-affected world might be a broken world, where no favorable conditions hold and notions which we were used to – such as rights or the ideal of equality – are no longer valid and should be replaced with a new ethic. No appeal to entrenched moral intuitions will work in such a new world

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.
