This paper asks how rule-consequentialism might adapt to very adverse futures, and whether moderate liberal consequentialism can survive into broken futures and/or futures where humanity faces imminent extinction. The paper first recaps the recent history of rule-consequentialist procreative ethics. It outlines rule-consequentialism, extends it to cover future people, and applies it to broken futures. The paper then introduces a new thought experiment—the “ending world”—where humanity faces an extinction that is unavoidable and imminent, but not immediate. The paper concludes by explaining why this thought experiment challenges rule-consequentialism's commitment to procreative liberty, and briefly asking how rule-consequentialism might respond to that challenge.

从布拉德到更糟：规则结果主义和不受欢迎的未来

本文探讨了规则后果主义如何适应非常不利的未来，以及温和的自由后果主义是否能够在破碎的未来和/或人类面临即将灭绝的未来中生存。本文首先回顾了规则结果主义生育伦理学的近期历史。它概述了规则结果主义，将其扩展到涵盖未来的人，并将其应用于破碎的未来。该论文随后介绍了一个新的思想实验——“末日世界”——人类面临着不可避免且迫在眉睫但并非立即发生的灭绝。本文最后解释了为什么这个思想实验挑战规则后果论对生育自由的承诺，并简要询问规则后果论可能如何应对这一挑战。
