Philosophy for an ending world

This chapter explores the philosophical implications of a slowly ending world -- a place where humanity faces unavoidable and imminent (but not immediate) extinction. Section 1 introduces this new thought experiment. Section 2 asks why we should think about unavoidable, imminent, non-immediate human extinction. The author argues that his slowly ending world is both an interesting thought experiment and a credible possible future. Sections 3 to 5 explore three topics in detail from the perspective of this slowly ending world: philosophical pessimism, procreative ethics, and multigenerational optimism. The goal of the chapter is not to defend any particular conclusions about the philosophy of the ending world, but simply to motivate its exploration.
