TWENTY-THREE CENTURIES OF THE ONE-WORLD IDEA · FROM THE COSMOPOLIS TO THE AI-GOVERNANCE MOMENT
★ WHERE THE DREAM OF ONE GOVERNMENT COMES FROM — AND WHERE THE SERIOUS THINKERS ACTUALLY STOOD ★

Long before an AI could co-govern anything, people argued about whether the world should have one government at all — and if so, what kind. The answers split. Some wanted a single emperor; most, the careful ones, wanted a federation of free states that could always leave. This is that lineage, plotted honestly: click any thinker to hear what they actually proposed, not the caricature.

What the map shows

three honest readings you can see with your own eyes
The green middlefederation of free states

The serious mainstream — Saint-Pierre, Bentham, Kant, the Bahá'í writings, Willkie — clusters in federation: a union of sovereign states, bound by law but free to leave. Not one ruler. A league.

The red floor is nearly emptysingle sovereign

Almost nobody serious wanted a single world sovereign. Dante's universal emperor (1313) is a medieval outlier; Wells briefly reached for a world state — and Kant expressly warned that one would decay into "a soulless despotism… the graveyard of freedom."

Today sits at the topsoft norms, 2023–25

The AI-governance moment lives in the weakest tier — declarations and advisory bodies, nothing binding or global. The idea is 2,300 years old; the institutions for its newest problem barely exist.

Two layers, honestly

What is verified, and what is a frame

Verified. Every date, author, and claim on the timeline was fact-checked against primary and reference sources. The load-bearing corrections are real: Kant argued for a federation, not a world state, and warned the latter becomes "a soulless despotism"; Wells's "World Brain" was a global encyclopedia — a knowledge network — not a government; the Russell–Einstein Manifesto was anti-nuclear, not a call for world government; and as of 2025 no binding global AI authority exists — only declarations (Bletchley), advisory bodies (the UN's), and proposals (an "IAEA for AI," a "CERN for AI").

The frame. The four-band "form of authority" axis is my ordering, a lens laid over the record to make a real pattern legible — it is an interpretation, not a fact in the sources. A few placements are judgment calls (the EU straddles federation and limited authority; the Bahá'í writings blend the spiritual and the institutional). The lens is honest, but it is a lens.

The oldest lesson in the newest problem: the world has needed coordination for millennia and has almost never trusted a single ruler to provide it. The Concord next door is that lesson, made runnable. WBR · The World Brain · the lineage of the one-world idea · Legal domain · UD0
