Abstract

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.
