Why prior generations missed some of the biggest priorities of all | Tom Moynihan (2021)

Tom Moynihan, Rob Wiblin

Moynihan argues that pre-modern thinkers universally rejected the possibility of permanent human extinction due to the "Principle of Plenitude," a worldview asserting that all potential realities must eternally recur. This intellectual barrier crumbled in the 18th and 19th centuries through paleontological evidence and the shift from cyclical time to linear contingency, enabling the concept of irreversible species death. Consequently, this historical transition redefined human value as fragile rather than fixed, establishing the ethical imperative for the current generation to intentionally manage existential risks.
