# Great Filter

> **the civilizational threshold.** A proposed barrier that prevents most life from becoming long-lived, spacefaring civilization.

## Origin

Great Filter emerged where civilizational scale meeting a bottleneck between potential and survival became nameable. The archive distinguishes a traceable source lineage from resemblance discovered after the fact. Because civilizational scale meeting a bottleneck between potential and survival changes the conditions under which every actor chooses, provenance work must identify who can decide, inspect, refuse, revise, profit, and obtain remedy.

## What It Is

A proposed barrier that prevents most life from becoming long-lived, spacefaring civilization. In the Oracle it is classified as Forces, while its evidence layers determine how literal, historical, fictional, experiential, or symbolic a particular interpretation may be.

## Cultural History

The cultural life of Great Filter follows civilizational scale meeting a bottleneck between potential and survival across institutions and communities. Each reuse changes what the symbol permits people to notice or ignore. At collective scale, civilizational scale meeting a bottleneck between potential and survival becomes visible in norms, incentives, contagion, and collective attention; this matters because coordination becomes domination when accountability and exit exist only for the powerful.
