How should utilitarians think about the future?

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.
