## The Source

Wiener, N. (1948). *Cybernetics: Or Control and Communication in the Animal and the Machine*. MIT Press. Cambridge, MA. ISBN 978-0-262-73009-9.

## The Claim

Living things and machines obey identical control laws. Feedback loops govern both. Information bridges the gap between organism and engine.

## The Context

World War II demanded anti-aircraft predictors. Wiener built gun-aiming mathematics. He saw the same equations in heartbeats, thermostats, and servos. The Macy Conferences (1946–1953) forged a new vocabulary. Shannon brought information. Von Neumann brought computation. Wiener brought feedback. Cybernetics was born in war and named in peace — from the Greek *kubernetes*, steersman.

## The Evidence

Wiener proved that control systems share three components regardless of substrate: sensor, comparator, actuator. A thermostat and a pancreas both measure, compare, and correct. He derived the Wiener filter for signal prediction. He showed that noise and entropy are mathematically kin. The same equations describe blood-glucose regulation and cruise control.

## The Convergence

This source instantiates **C07 — Feedback / Cybernetics / Homeostasis**. It also feeds **C06** (Information / Entropy) through the Macy Conference cluster. Wiener's feedback is the ancestor pattern to autopoiesis (**C12**): organizational closure begins with circular causality. The GRAIN axiom it proves: systems that sense and correct persist. Systems that do not, dissolve.

## The Honest Limits

Cybernetics overreached into sociology and economics. Those extensions remain contested (T2). The Macy Conferences created intellectual incest: Wiener, Shannon, von Neumann, and Ashby shared ideas before publishing. Independence is MODERATE, not HIGH. Cannon discovered homeostasis empirically in 1926 — twenty-two years before Wiener — without invoking feedback mathematics. The rival claim stands: some stability is passive equilibrium, not active control. Doolittle (2019) demolished strong Gaia. Not everything that looks like feedback is.
