"It would be some consolation for the feebleness of our selves and our works if all things should perish as slowly as they come into being; but as it is, increases are of sluggish growth, but the way to ruin is rapid." Lucius Anneaus Seneca, Letters to Lucilius, n. 91

The Seneca Effect

Why Growth is Slow but Collapse is Rapid

Authors: Bardi, Ugo

Presents wisdom from an ancient Roman Philosopher that you can use today. Explains why technological progress may not prevent societal collapse. Provides a true systems perspective on the widespread phenomenon of collapse. Highlights principles to help us manage, rather than be managed by, the greatest challenges of our times.
The essence of this book can be found in a line written by the ancient Roman Stoic Philosopher Lucius Annaeus Seneca: "Fortune is of sluggish growth, but ruin is rapid". This sentence summarizes the features of the phenomenon that we call "collapse," which is typically sudden and often unexpected, like the proverbial "house of cards." But why are such collapses so common, and what generates them? Several books have been published on the subject, including the well known "Collapse" by Jared Diamond (2005), "The collapse of complex societies" by Joseph Tainter (1998) and "The Tipping Point," by Malcom Gladwell (2000). Why The Seneca Effect?
This book is an ambitious attempt to pull these various strands together by describing collapse from a multi-disciplinary viewpoint. The reader will discover how collapse is a collective phenomenon that occurs in what we call today "complex systems," with a special emphasis on system dynamics and the concept of "feedback." From this foundation, Bardi applies the theory to real-world systems, from the mechanics of fracture and the collapse of large structures to financial collapses, famines and population collapses, the fall of entire civilzations, and the most dreadful collapse we can imagine: that of the planetary ecosystem generated by overexploitation and climate change. The final objective of the book is to describe a conclusion that the ancient stoic philosophers had already discovered long ago, but that modern system science has rediscovered today. If you want to avoid collapse you need to embrace change, not fight it. Neither a book about doom and gloom nor a cornucopianist's dream, The Seneca Effect goes to the heart of the challenges that we are facing today, helping us to manage our future rather than be managed by it.

Seneca's pyramids: how fast did the Mayan civilization fall?


Originally published on Cassandra's legacy on Wednesday, January 14, 2015



Monument building cycle of the Mayan civilization. From "Sylvanus G. Morley and George W. Brainerd, The Ancient Maya, Third Edition (Stanford University Press, 1956), page 66.". Courtesy of Diego Mantilla.



Once you give a name to a phenomenon, you can focus your attention on it and learn more and more about it. So, the "Seneca Cliff" idea turns out to be a fruitful one. It tells us that, in several cases, the cycle of exploitation of a natural resource follows a forward skewed curve, where decline is much faster than growth. This is consistent with what the Roman philosopher Lucius Annaeus Seneca wrote: "increases are of sluggish growth, but the way to ruin is rapid." With some mathematical tricks, the result is the following curve:


This curve describes the behavior of several complex systems, including entire civilizations which experienced an abrupt collapse after a long period of relatively slow growth. In my first post on the seneca cliff, I already discussed the collapse of the Mayan Civilization (*)



Here, you can see the the Seneca behavior, although the data for the Maya population density seem to be rather qualitative and uncertain. However, the data that I received recently from Diego Mantilla (see at the beginning of this post) are clear: if you take monument building as a proxy for the wealth of the Mayan civilization, then the collapse was abrupt, surely faster than growth.

Something similar can be said for the ancient Egyptians, although the data for pyramid building are more sparse and uncertain than those for the Maya. Finally, also the Roman civilization appears to have collapsed faster than it grew.

So, the Mayans didn't do better than other civilizations in human history. As other civilizations did, they moved toward their demise by dragging their feet, trying to avoid the unavoidable. They didn't succeed and they didn't realize that opposing the collapse in this way is a classic example of "pushing the levers in the wrong direction". It can only postpone collapse, but in the end makes it more rapid.

Will we do any better than the Mayans? One would hope so, but........
