The Chain of Being: A Hierarchy of Morality.

For centuries, philosophers, theologians, and scientists have used the idea of the Great Chain of Being to rank all beings, from demons to animals, humans, and gods, along a vertical dimension of morality. Although the idea of a chain of being has largely fallen out of academic favor, we propose that people still use an embodied vertical moral hierarchy to understand their moral world. This social cognitive chain of being (SCCB) encapsulates a range of research on moral perception including dehumanization (the perception of people as lower on the SCCB), anthropomorphism (the perception of animals as higher and the perceptions of gods as lower on the SCCB), and sanctification (the perception of people as higher on the SCCB). Moral emotions provide affective evidence that guide the perception of social targets as moral (e.g., elevation) or immoral (e.g., disgust). Perceptions of social targets along the SCCB enable people to fulfill group and self-serving, effectance, and existential motivations. The SCCB serves as a unifying theoretical framework that organizes research on moral perception, highlights unique interconnections, and provides a roadmap for future research.
