So why does evolution does not explain everything, and especially culture

Here is summarized the conclusions drawn by Felipe Fernàndez-Armesto in his book "A Foot in the River":

Basic to entente biology and history is the acknowledgement of three facts: that culture is not uniquely human; that the existence of culture depends on evolution in the sense that we can only do anything with the physical and cerebral equipment evolution has given us; but that culture also changes independently of evolution, which should not be expected to have infinitely elastic powers of explanation.
(Chapter 8, "Towards the planet of apes") Felipe Fernàndez-Armesto goes on:
The mutations that make for a multiplicity of culture are different from those that kick off organic changes: they are capricious, but not random; they are devised by minds, not spontaneous; typically, they do not replicate according to the incidence of any advantage, nor does their success or failure respond necessarily to environmental constraints or opportunities.
(Chapter 8, "Towards the planet of apes")

Additional quotes from "A foot in the river" by Felipe Fernández-Armesto

"There is no reason for God and Darwin to be rival deities--except in the minds clouded by passion"
Chapter 5, The Limits of Evolution
The effort to invoke biology to explain history has failed because it is basically ill conceived. History, to quote a collaboration between an eminent scientist and an eminent historian, is 'too generally messy' for scientific treatment. Societies do not change by transmission and inheritance, but by acquisition and acculturation. History seems unDarwinian precisely because it is a story of the survival of the unfittest. The societies we class as least evolved, least complex, least developed, with fewest parts, last longer--while elaborate civilizations become playgrounds and photo-ops for romancers amid ruins. Culture is just too different from organic life to invite the same kind of explanation. Cells are self-organizing systems that adapt to survive and resist permeation by hostile intrusions from outside. Cultures, by contrast, are built for chaos and as prone to self-destruction as to survival.

Quotes from "A foot in the river" by Felipe Fernandez-Armesto

"Maybe there no causes to know, or, at least, maybe much that happens is uncaused. Anyone who thinks that everything is explicable as the result of something else--who sees causation as the 'cement of the universe', making each event adhere closely to the next--may be the victim of an unwarranted assumption. 'Just-so' explanations may be the only true ones." (Chapter 3)
A quote from early in Chapter 3 where the author starts to develop his theory that future human events might not be predictable, a theory that goes opposite to that of Pierre-Simon Laplace but is in line (albeit for different reasons) with that of Karl Popper.
"Empathy is the heart of understanding" (Chapter 3)
 A quote that summarizes, according to the author, a principle of anthropological field work as well as of life followed by Franz Boas.

La France, terre d'accueil?

"Si la France ne figure plus parmi ce qu'on appelle les Grands, il lui reste encore un moyen pour s'imposer à l'histoire: c'est d'être le dernier pays où l'homme exilé, désolé, désespéré, recontrera, sans qu'il ne lui soit posé de questions, une main qui se tende à lui, un foyer où refaire sa vie."
Emmanuel Mounier, Combat, 11 Mai 1946.

L'Allemagne et l'identité nationale

Christian Estrosi, un parlementaire français, vient récemment de commenter que si l'Allemagne s'était posée la question de l'identité nationale, le Nazisme n'aurait pas existé. Ce commentaire est une distortion de l'Histoire. Même si on ne peut pas faire un lien directe entre la pensée Allemande du 18e et 19e et le Nazisme du 20e, et rendre pour responsable Herder, Goethe et Nietzsche (meme si Heidegger était lui-même un Nazi), il est en revanche faux de dire que l'Allemagne n'a pas participé à la question de son identité. Au contraire! Pendant plus d'un siècle, sous l'emprise d'abord d'un empereur-dictateur, puis envahie par un autre empereur-dictateur, Napoléon, un derivé malheureux de la Révolution Française, l'Allemagne n'a cessé de se poser cette question. Heder a été l'un des premiers a exprimé le plus clairement cette question et a posé les fondations d'une philosophie où le peuple Allemand peut enfin s'épanouir et definir une identité specifique au sein même d'un environnement universalisant.

Dans cette thèse de Cambridge (en Anglais), même si l'auteur démontre qu'il y a une cassure dans la pensée Allemande avec le Nazisme, il ne peut pas ignorer ce grand débat de l'identité nationale qui a fait vibrer l'Allemagne (lisez en particulier le lien "II.The Great Debate" de son introduction).

Restons fidèle à l'Histoire.

A summary of "A thousand years of nonlinear history": the geological component and why the West dominates the World

Manuel De Landa ambitiously borrows the vocabulary and concepts from the science of nonlinearity and complex systems and applies them to the history of Europe from the year 1000 to 2000. The main goal of the book is to draft a possible schematic trajectory explaining the domination of Europe during that period over the rest of the world, especially the empire of Islam and China. The idea is that this domination came up because of the lucky congruence of multitude of complex and interacting economic, climatic, geographic and social processes that triggered auto-catalytic processes, that it is processes fuelling themselves via positive feedbacks, and not because of either the fate of History as Marx suggested, the sole power of some top-down political and economical concept as capitalism and its (really) "invisible hand", or a fundamental dominating aspect of the European people, such as a psyche or a religion shaped for "success". In this sense, De Landa follows the traces of many (western) authors who have been trying to re-equilibrate the idea that we have of the creative power of the different cultures in the History and put back the spoiled child 'Europa' to its right place, as Guns, Germs and Steel by Jared Diamond (one of the best book and theory ever) successfully did.

The originality of De Landa is to avoid at every instant the use of any subjective concious or unconscious explanations by constantly using the scientific language, metaphors but also actual processes from the science of complex systems.

The first part deals on the geological aspect of the European society, its cities, institutions and economical system:

"From this point of view cities arise from the flow of matter-energy, but once a town's mineral infrastructure has emerged, it reacts to those flows, creating a new set of constraints that either intensifies or inhibits them. Needless to say, the walls, monumental buildings, streets, and houses of a town would make a rather weak set of constraints if they operated on their own. Of course, they do not. Our historical exploration of urban dynamics must therefore include an analysis of the institutions that inhabit cities, whether the bureaucracies that run them or the markets that animate them. Although these institutions are the product of collective human decision making, once in place they also react back on their human components to limit them and control them, or, on the contrary, to set them in motion or accelerate their mutation."
Manuel De Landa, A thousand years of nonlinear history, Geological history: 1000-1700 AD


Notice the vocabulary of dynamics employed and the numerous feedback loops considered in that explanation. One of the virtuous cycle that exists, according to De Landa, is the combination of markets and anti-markets. The first are actual markets, composed of small-scale and truly capitalistic companies where competition rules, while the second are composed of large-scale companies that are anti-capitalistic by preventing competition to exercise its force:
"Markets and bureaucracies, as well as planned and unplanned cities, are concrete instances of a more general distinction: self-organized meshworks of diverse elements, versus hierarchies of uniform elements. But again, meshworks and hierarchies not only coexist and intermingle, they constantly give rise to one another.
[...]Thus, once markets grew past the size of local, weekly gatherings, they were ranked and organized form the top, giving rise to a hybrid form:a hierarchy of meshworks. The opposite hybrid, a meshwork of hierarchies, may be illustrated by the system of power in the Middle Ages."
Manuel De Landa, A thousand years of nonlinear history, Geological history: 1000-1700 AD

The chance of Europe, that Islam or China did not have, was that it was never too anarchic nor too controlled. Its chance has been the presence of that multitude of people, competing each other over that relatively small piece of land, where the virtuous cycle of markets and anti-markets survived until invading the institutions and the psyche of Europe. In some sense, even without mentioning it, De Landa describes here the concept of the edge of chaos, the limit between too much order and too much randomness; only at the edge, life and creativity survive. Islam and China have both a too strong central commandment that prevented, according to De Landa, the local market-like processes to develop and bring the innovations to the high level necessary for a civilisation to win the evolutionary game:
"The emergence of powerful nation-states, and the concomitant decrease in the autonomy of the cities they absorbed (and even of the city-states that remained independent), could have brought the different forms of self-stimulating dynamics we have described to a halt. That this did not happen was due yet to one more form of autocatalysis unique to the West: continued arm races. [T]his type of self-stimulation depended in turn on the fact that the nations of Europe, unlike China and Islam, were never able to form a single, homogeneous empire, and have remained until today a meshwork of hierarchies. It was within this meshwork that advances in offensive weaponry stimulated innovations in defense technology, leading to an ever-growing armament spiral.
[...]
Many of the inventions that Europeans used to colonize the world (the compass, gunpowder, paper money, the printing press) were of Chinese origin, while Europe's accounting techniques and instrument of credits (which are often cited as examples of her unique «rationality») came from Islam. Thus, nothing intrinsic to Europe determined the outcome, but rather a dynamics bearing no inherent relationship to any culture. [A]n excess of centralized decision making in the East kept turbulent dynamics under control, while they raged unobstructed in the West. To be sure, at several points in her history Europe could have become a unified hierarchy, and this would have ground these dynamics to a halt. This happened in the sixteenth century with the Hapsburg Empire, and later on with the rise of Napoleon and Hitler. Yet all these efforts proved abortive, and European nations remained a meshwork."
Manuel De Landa, A thousand years of nonlinear history, Geological history: 1000-1700 AD

As again, those theories and trajectories are hard to proved. They are only suggestive but they have the merit to bring a more moderate albeit complex view of the world and to liberate ourself from the extremist, at times naive and too simplistic, visions that we have of our world. The Truth might lay somewhere in between.

Dostoevsky on the predictability of human history

"They fight and fight and fight; they are fighting now, they fought before, and they'll fight in the future... So you see, you can say anything about world history. Except one thing, that is. It cannot be said that world history is reasonable."
Dostoevksy, Notes from underground, cited by Niall Ferguson in The cash nexus.

This post follows the series on the relative importance in irrationality in human affairs.

The notion of time

This is a much too brief place to discuss the full history and meaning of the notion of time. This post will progressively fill up...with time.

The first idea that I would like to start with is the fact that time, in terms of the dynamical evolution of the objects and systems which surround us, has not always been an obvious concept in the History. A surprising example is the static view of the world that the Greeks had. Heracles may have been the only one at his time to notice that "you do not always cross the same river", that things are changing and are not immutable.

More generally, the Greeks thought the world was in balance. As Ludwig von Bertalanffy notices, "Greek physics did not contain a time dimension" (General System Theory, Chapter 10). That is why, among other things, the Greeks spent so much time on geometry.

The question that I would like to ask is if the notion of time was absent only from the teachings and the work of the scholars only or if it was generally absent from the psyche of people. On one hand, it is hard to imagine that anybody could not have noticed that objects can fall, things got unbalanced and stones have trajectories. Should apes notice that the world is constantly changing? Or did the humans have to learn such concept which appears so "obvious" to us?

If you see an ape or an ancient Greek, don't hesitate to ask him.

To be continued.

It's the demography!

Emmanuel Todd and Youssef Courbage, an intellectual and a demograph, have written a book The rendez-vous des civilisations (a title that I would translate as "The civilizations will unite"), which takes an opposite view of the much controversial book by S. Huntington The clash of civilizations.

In this book, that I have not read but which is reviewed by Pierre Assouline, it is argued that Islam, which is at the center of the "problem", is, contrary to what we might think, already on its way of being westernized, and this is deduced by a pure look at the demography of muslim populations: the birth rate passed from 6.8 to 3.7 child per women between 1975 and 2005. The thesis is the following: the intellectual and cultural evolution of a people depends much on its demography than on its mood. In particular, the highest the birth rate, the more powerful religion is and inversely. Apparently, this lecture fits well the evolution of christian people in Europe and the authors argue in their book that this is what is happening as well in muslim nations. Thus, for them, the future is bright, and the different civilizations are already on a road of convergence.

Although optimist, this book has nonetheless received many criticism regarding the simplicity of their theory and the lack of cultural factors to judge the future. Critics that I think are well founded. But it is worthy and courageous to give a different perspective, one which contradicts the much too fearful theory of S. Huntington.

Les "Etrangers" et la Résistance

Les "Etrangers" formaient une bonne part de la Résistance dans le maquis français (Polonais, Italiens, Espagnols, etc) durant la Seconde Guerre Mondiale. Leur "étrangeté" leur a valu parfois d'être sacrifiés vers la fin de la guerre par la Résistance "française"...


"Alors je me souviens que le mot "Etranger" est une des plus belles promesses du monde, une promesse en couleurs, belle comme la Liberté."
Marc Levy, Les Enfants de la Liberté, dernière phrase.
