Mo­ral cir­cle expansion

TagLast edit: 9 May 2021 19:23 UTC by Pablo

Moral circle expansion is the attempt to expand the perceived boundaries of the category of moral patients. It has been proposed as a priority cause area (Anthis & Paez 2021) and as a heuristic for discovering cause X (Vaughan 2016).
