The challenges we face are enormous. But we can still secure a positive future for our planet, and for everyone on it. In What We Owe The Future, philosopher William MacAskill persuasively argues for longtermism, the idea that positively influencing the distant future is a moral priority of our time. It isn't enough to mitigate climate change or avert the next pandemic. We can ensure that civilization would rebound if it collapsed; cultivate value pluralism; and prepare for a planet where the most sophisticated beings are digital and not human. 'Unapologetically optimistic and bracingly realistic, this is the most inspiring book on 'ethical living' I've ever read.' Oliver Burkeman, Guardian 'A monumental event.' Rutger Bregman, author of Humankind 'A book of great daring, clarity, insight and imagination. To be simultaneously so realistic and so optimistic, and always so damn readable... well that is a miracle for which he should be greatly applauded.' Stephen Fry
