Echoes on AI

One hundred minds that shaped human history — from Gilgamesh to the Hellenistic age — reconstructed to ask a single question: how would each of them build artificial intelligence if they were alive today?

Where Asimov's psychohistorians forecast the future of the many, these chapters reconstruct the inner architecture of the singular.

Five hardcover tomes. Twenty minds each. A collection that will keep growing — forward through history, all the way to 1905.

100 minds 5 tomes now Antiquity → Hellenistic
A different kind of encyclopedia — one that reads the past as a question about the future of intelligence.

Each entry begins with a real historical mind — what they wrote, what they believed, and what others recorded of them — and projects it forward. What was their theory of mind? How would they confront AGI? What would they build today?

The result is part history, part thought experiment, part engineering: a portrait of a person, and a blueprint for the machine they might have made. Every mind is treated as unique, and reconstructed as faithfully as the surviving record allows.

The method

Every mind, rendered twice.

Each thinker is reconstructed on two planes — one for the shape of the person, one for the shape of the machine they'd design.

Plane one

The mind-map

An interactive three-dimensional map of the personality and worldview behind each thinker — the ideas, tensions and instincts that made them who they were, abstracted into a form you can move through.

Plane two

The neural model

A runnable, built-from-scratch neural architecture — an imagining of the AGI each mind might design, its mechanism drawn from the way that particular thinker understood thought itself.

The interactive maps and runnable models live on the platform — the tomes hold the full reconstructions, the reasoning, and an exclusive summary of every mind. See them on Artificiology →

The collection

Five tomes to begin.

Twenty minds in each volume, in the order history met them. Front and back are shown for every tome; more volumes are already in production.

One hundred minds are only the beginning. The encyclopedia moves forward through history — the axial age, Rome, the medieval and early-modern worlds, the Enlightenment and the long nineteenth century — toward the full one thousand, ending in 1905.

Inside a tome

What each entry holds.

Every mind gets a full chapter — a reconstruction built from the real record, not a summary.

A deep reconstruction

A long-form portrait of the mind — their life, context and philosophy — grounded in surviving works and current scholarship.

Their theory of mind

What this thinker believed intelligence was — and how that belief would shape the machine they'd build today.

How they'd build AGI

A concrete imagining of the architecture each mind would design — the mechanism that matches how they thought.

Original artwork

Commissioned images throughout each chapter — the person, their world, and the intelligence they envisioned.

An E-AGI reading

Each mind scored across the eight dimensions of the Artificiology E-AGI Barometer — from cognition to autonomy.

Sources you can check

Real, verifiable references for every reconstruction — the surviving texts and the scholarship behind them.

The living companion

Every tome includes complementary accessed to the The Artificiology platform

That brings the minds to life — free with any tome you buy.
