What We Owe the Future

Philosopher William MacAskill makes the case for longtermism: the idea that positively influencing the long-run future is a key moral priority of our time. Because vast numbers of people could yet live, he argues, the choices we make now about technology, climate, and catastrophic risk carry enormous moral weight. A founder of the effective altruism movement, MacAskill blends philosophy, history, and economics into an ambitious, readable argument for taking future generations seriously.
