This is why it now seems that many natural systems cannot simply be explained by a reductionist study of their parts. One of the most emblematic examples is that of the collectively built artefacts of insect societies Camazine et al. For example, termites make immense nests, rising several metres above the ground and with an architecture which is reminiscent of human structures, as Figure 1. To try to explain how these structures are built, the study of individual termites, for example the precise study of all their neural wiring, is absolutely not sufficient.
The architecture of termite nests is the self-organizd result of local interactions among thousands of individuals. The superstructure is rather the result of the dynamic interactions in the environment of thousands of termites, in the same way as the symmetrical structure of ice crystals is the result of the interactions of water molecules, and not a projection to the macroscopic level of structures already present at the microscopic level.
Such concrete examples of the use of the concept of self-organization, and of explanations of natural forms in terms of systemic properties, are now abundant, and are at the heart of the most advanced research of more and more physicists and biologists.
The sciences of complexity have thus demonstrated the fundamental usefulness of the concept of self-organization for the explanation of natural phenomena involving physical structures and certain biological structures characterizing the morphology or behaviour of simple animals like insects.
We are now at the dawn of a new and decisive phase in this scientific revolution: researchers in complexity theory are beginning to tackle the understanding of mankind itself, using these new tools. Rather than concentrating on each organ in isolation, there is now an attempt to understand their complex interactions in an organism considered as a whole in which each element is integrated with the others.
This has opened up new theoretical vistas, for example the understanding of cancers Kitano, or of morphogenesis Kupiec and Sonigo, , which, according to the authors, is seen not as the serial execution of a genetic programme but as the self-organized dynamic of the whole ecosystem formed by the cells competing for nourishment.
The advocates of self-organization do not stop there: the human brain, and thus the phenomena of sensation and thought, are also under the strong influence of features of spontaneous organization in their structure.
Indeed, the brain, composed of billions of neurons dynamically interacting among themselves and with the outside world, is the prototype of a complex system.
For example, as I will show in this book, self-organization could be at the heart of the capacity of our brains to categorize the perceived world, that is, to organize the continuous flux of perceptions into atomic psychological objects. But the main subject of this book goes beyond speculation about the brain as a self-organized system.
We are today on the brink of a major advance in science: that of a naturalized understanding of what makes humans so exceptional, their culture and language.
Indeed, if culture and language have been the subjects of investigation by social sciences for centuries, scientists have not yet succeeded in anchoring an understanding of them in terms of 6 Self-Organization in the Evolution of Speech their material biological substance, i.
Now, the tools of complexity begin to make it possible. This is what I will illustrate in this book, concentrating on a quite precise example, that of the origin and shaping of one of the pillars of human language—speech, the outward form and vehicle of language—seen as systems of shared and combinatorial sounds particular to each language community.
To understand the ongoing revolution on this particular question, I will first outline the main trends in its history. It is their main activity, an activity which, moreover, sets them off from the rest of the animal kingdom.
Human language is a communication medium of unequalled complexity. It is a conventionalized code which lets one individual share his ideas and emotions with others, talk of the colours in the sky and also of distant landscapes, of past events, even of how he imagines the future, of mathematical theorems, of invisible properties of matter, and of language itself. Besides that, each language defines a system which is peculiar to its speakers, an original way of organizing sounds, syllables, words, and sentences, and of spelling out the relationship between these sentences and the concepts which they convey.
Today there are thousands of languages spoken in human communities. Over time, some languages die and others are born. The number of languages which have existed is estimated at over half a million. It is hard to imagine humanity without language.
And yet, a long time in the past, humans did not speak. This raises one of the most difficult questions in science: how did humans come to talk? A further question follows naturally: how do languages evolve? These two questions, concerning the origin of the language faculty and the evolution of languages, have been focused on by many thinkers in centuries gone by, particularly in the nineteenth century.
Many such theories were developed without the benefit of any empirical or experimental constraint. They were equally devoid of reasoned arguments and scientific method, to the point where the Linguistic Society of Paris ruled that such questions should be raised no more in the context of scientific discussion.
This ruling initiated a century of almost total lack of progress in research in this domain. The Self-Organization Revolution 7 Advances in neuroscience, cognitive science, and genetics towards the end of the twentieth century have put these questions back into the centre of the scientific arena. On the one hand, modern neuroscience and cognitive science have made enormous progress in understanding the general functioning of the brain, and especially the way in which language is acquired and processed.
These developments have allowed the study of language to relate to the natural sciences, that is, to ground the abstract systems which linguists describe in the biological matter of which humans and their environment are composed. In short, natural sciences have taken over questions previously in the domain of the social sciences.
This new light on the workings of language and the brain have provided researchers with the constraints whose absence undermined the speculations about the origins of language of the nineteenth century. On the other hand, progress in genetics has turned the spotlight on neoDarwinian theories of evolution, both confirming some of its foundations with the discovery of genes, for example, along with their mechanisms of variation and allowing its predictions to be tested, often successfully, thanks to the sequencing of the genomes of different species of animals so that we can reconstruct their phylogenetic trees and trace their evolutionary history.
In particular, the sequencing of the human genome, along with that of other animals such as chimpanzees and monkeys, makes it possible to specify the relationships between humans and their ancestors. Thus, driven by vigorous evolutionary biology, which simultaneously provides an impressive body of observations and a solid explanatory framework, the question of human origins has become a central theme in science.
And, quite naturally, the origins of language this being one of the distinctive features of modern humans has become, as in the nineteenth century, a beacon for research.
In fact it poses a puzzle with immense ramifications which go beyond the competence of each individual discipline. First, the two big questions must be decomposed into subquestions which are themselves already quite complex. What, in fact, is the language faculty?
What is a language? How are sounds, words, sentences, and representations of meaning related to each other? How does the brain 8 Self-Organization in the Evolution of Speech represent and process these sounds and sentences and the concepts which they convey?
Owing to this, the forthcoming forms simultaneously diminish going back to the primeval source.

This was shown through his research on optic arrays. Secondly, he formulated the idea of three-dimensional space being conceptual. To Gibson, perception is a compilation of the person's environment and how the person interacts with it. Army Air Force. Here, he delved into thoughts on how imperative perception is on daily functions. Form perception , on one hand, is a display of two static displays, whereas object perception, involves one of the displays to be in motion.
He did work on adaptation and inspection of curved lines, which became a precursor for perceptual research later. He claimed that the environment decides perception, and that meaning is in what the environment "affords" the observer. He studied the concept of optical flow later published as part of his theory of affordance.
According to Gibson, one determines the optical flow which can be described as the apparent flow of the movement of objects in the visual field relative to the observer using the pattern of light on the retina.
This concept has been extremely influential in the field of design and ergonomics : see for example the work of Donald Norman who worked with Gibson, and has adapted many of his ideas for his own theories. Gibson argued strongly in favour of direct perception and direct realism as pioneered by the Scottish philosopher Thomas Reid , as opposed to cognitivist indirect realism. He termed his new approach ecological psychology.
He also rejected the information processing view of cognition. Gibson is increasingly influential on many contemporary movements in psychology , particularly those considered to be post-cognitivist. Together they proposed perceptual learning as a process of seeing the differences in the perceptual field around an individual. An early example of this is the classic research study done by Eleanor Gibson and R. Walk, the visual cliff experiment. In this experiment an infant that was new to crawling was found to be sensitive to depth of an edge.
The environment is what we perceive at any given moment. All animals are able to perceive. Humans perceive the environment directly. Affordances[ edit ] Gibson coined the noun affordance. Affordances require a relationship in which the environment and the animal can work together.
An example is that mankind has changed the environment to better suit our needs.
When coming across Earth's natural steep slopes, man designed stairs in order to afford walking. In addition, objects in the environment can also afford many different behaviors, such as lifting or grasping.Owing to this, the forthcoming forms simultaneously diminish going back to the primeval source.
