Feedback

Feedback loops are everywhere in nature, especially when it comes to our mental lives and the incentive structures that regulate our behavior in a society.

The quintessential book on the subject, Godel, Escher, Bach: an Eternal Golden Braid makes the case that feedback loops are the key to understanding mathematics, art, and human cognition. A free online course from MIT is available to help get the most out of this seminal work that, more than any other book, forms the groundwork understanding metaculture.

Self-reference, at the heart of the feedback loop, is also the central principle of the fractal.
