Causa sui (Latin pronunciation: [kawsa sʊi], meaning “cause of itself” in Latin) denotes something which is generated within itself. This concept was central to the works of… Ernest Becker, where it relates to the purpose that objects can assign to themselves.

In… Becker’s case, the concept was often used as an immortality vessel, where something could create meaning or continue to create meaning beyond its own life.

While Wikipedia frames the “causa sui” project optimistically, Becker viewed the effort as doomed… humans don’t want cultural immortality, they want ACTUAL immortality. And that can’t come from something “generated within one’s self.” It must come from beyond, from the “Uncaused” one.
