Response to recent criticisms of longtermism

Abstract

This article responds to two recent essays critical of longtermism, a philosophical view that prioritizing the long-term future is a key moral priority. The author argues that the criticisms misunderstand longtermism, misrepresent its positions, and fail to capture the heterogeneity of longtermist thought. The author introduces the core elements of longtermism, explains why it prioritizes existential risks over non-existential catastrophes, and addresses the concern that longtermism could be used to justify harm. The author also clarifies the relationship between longtermism and other concepts, such as transhumanism, space expansionism, and total utilitarianism, noting that they are not inherent components of longtermism. Finally, the author discusses the relationship between longtermism and technological development, arguing that longtermists are aware of the risks associated with technology and are actively working to mitigate them. – AI-generated abstract.
