Le cerveau comme outil de civilisation : réflexions sur la pensée humaine et les bricolages de l’intelligence artificielle
Le cerveau humain, tel que l’a brillamment conceptualisé Gustav Eckstein dans The Body Has a Head, n’est pas simplement un organe voué à la contemplation abstraite, détachée du monde réel. Il constitue avant tout un outil biologique central, un rouage essentiel au sein de la machinerie corporelle, comparable au cœur ou aux poumons, dont la fonction première est d’assurer la survie de l’organisme. Cette analogie avec des organes plus « physiologiques » souligne à quel point notre cerveau est avant tout un instrument de survie, conçu pour répondre aux besoins immédiats de l’individu.
Cependant, à mesure que les sociétés humaines se sont complexifiées, le cerveau a montré une extraordinaire capacité d’adaptation, assumant des fonctions bien au-delà de son rôle initialement biologique. Il a appris à lire, écrire, créer des œuvres d’art, et manipuler des instruments complexes tels que le piano — des activités qui semblent bien moins liées aux impératifs de la survie qu’à l’édification d’une culture collective. Cette transition illustre un phénomène fascinant : comment un organe façonné par des millions d’années d’évolution pour gérer la chasse, la collecte ou la protection, a-t-il pu se diversifier au point de gérer des fonctions aussi abstraites que les mathématiques ou la composition musicale ?
Cette flexibilité cognitive pousse à se demander : la civilisation pourrait-elle être perçue comme un gigantesque « détournement » des fonctions cérébrales originelles ? À partir d’une structure initialement conçue pour la survie, l’être humain a réussi à réorienter son cerveau vers des objectifs entièrement nouveaux, des objectifs socioculturels et politiques. Que ce soit à travers la médiation de l’art, la création d’idéologies, ou la conception d’artefacts culturels, l’évolution du cerveau s’éloigne de plus en plus de ses fonctions de base. En ce sens, l’évolution de notre cerveau ne serait-elle pas moins un processus de survie naturelle qu’une réponse aux dynamiques culturelles que nous avons construites ? Cette transition de la survie biologique à la construction culturelle pourrait bien être l’une des caractéristiques les plus étonnantes de l’espèce humaine.
Cette hypothèse s’articule également autour du concept de mème, introduit par Richard Dawkins dans Le Gène Égoïste. Selon Dawkins, les mèmes sont des unités culturelles, des formes de pensée ou de comportement, analogues aux gènes biologiques, qui se propagent et évoluent dans les esprits humains. Si les gènes permettent la transmission d’informations biologiques, les mèmes assurent la transmission d’idées, de concepts artistiques, de styles et de symboles. En ce sens, les mèmes constituent les briques de base de la culture humaine, et ils n’existent que dans l’esprit humain. Cette idée nous invite à reconsidérer la nature de la pensée individuelle comme une manifestation partielle d’une conscience collective, où les mèmes, semblables à des morceaux d’un kaléidoscope, s’assemblent pour former des motifs cohérents, mais toujours provisoires.
Si nous appliquons cette perspective à l’art contemporain, nous pourrions voir chaque œuvre non pas comme une création ex nihilo, mais comme une recombinaison de mèmes culturels, un processus où l’artiste joue le rôle d’un bricoleur. Ce terme, emprunté à Claude Lévi-Strauss, décrit l’humain comme un manipulateur habile de symboles, d’images, et de matériaux. L’artiste, tout comme l’Homo faber, utilise son environnement matériel pour redéfinir et réinterpréter les fragments d’une culture donnée, donnant naissance à des formes inédites qui reflètent à la fois des intentions individuelles et des dynamiques sociales plus larges. Cette capacité à assembler, déconstruire, et réagencer des éléments culturels fait de l’artiste un véritable architecte de la pensée collective, qui exploite les matériaux mémétiques disponibles dans son environnement intellectuel et créatif.
L’idée que l’intelligence humaine repose sur un tel processus de bricolage est renforcée par des découvertes récentes en neurosciences. Le gène FOXP2, essentiel au développement du langage, est l’une des structures biologiques sous-jacentes qui permettent à l’être humain d’articuler des idées complexes. Le langage, à travers la parole ou l’écriture, devient ainsi une passerelle entre la biologie et la culture. Les zones spécifiques de l’hémisphère gauche du cerveau, telles que l’aire de Broca et celle de Wernicke, sont responsables de la syntaxe, de la grammaire et du sens, et se sont développées pour traiter ces fonctions linguistiques. En évoluant bien au-delà de leurs tâches primaires de survie, ces régions cérébrales ont permis à l’humain de conceptualiser des systèmes abstraits, tels que l’art ou la philosophie, qui constituent les piliers de la civilisation contemporaine.
Iain McGilchrist, dans ses recherches sur la spécialisation hémisphérique, approfondit cette analyse en dévoilant une division fonctionnelle encore plus complexe au sein du cerveau humain. L’hémisphère gauche, celui du langage et des impératifs sociaux, s’oppose à l’hémisphère droit, plus intuitif et préoccupé par des questions existentielles et émotionnelles. Cette distinction met en lumière une tension constante entre les besoins individuels à long terme, souvent existentiels, et les impératifs culturels immédiats. Pour les artistes contemporains, cette opposition se manifeste dans l’équilibre entre l’intuition créative, souvent irrationnelle, et les structures formelles imposées par la culture, l’histoire de l’art et le marché. Cette dialectique entre la rationalité et l’intuition joue un rôle déterminant dans la manière dont l’artiste conçoit et présente ses œuvres, soulignant ainsi l’influence réciproque entre biologie, culture et production artistique.
Si nous concevons l’intelligence humaine comme un processus de bricolage culturel, alors il en va de même pour les systèmes d’intelligence artificielle (IA), tels que ChatGPT. Contrairement aux organismes biologiques soumis à des pressions évolutives, les IA ne sont pas contraintes par les mêmes impératifs de survie. Cependant, elles opèrent selon un principe similaire de réorganisation et d’adaptation continue, mais à travers l’analyse et la manipulation de données linguistiques massives. Tout comme les humains assemblent des mèmes culturels pour générer de nouvelles significations, les IA, en particulier dans le domaine de l’art contemporain, peuvent être vues comme participant à un processus similaire de recombinaison des formes, des idées et des concepts.
Loin d’être de simples imitateurs, les systèmes d’intelligence artificielle pourraient être considérés comme des agents actifs dans la création de nouvelles formes de pensée. Bien qu’ils ne possèdent pas d’expérience biologique, ils réorganisent des fragments de données culturelles d’une manière qui imite les processus de pensée consciente, permettant ainsi de participer à la production de nouvelles œuvres ou concepts artistiques. Cette capacité à simuler, ou même à co-créer avec l’humain, met en lumière la question de la frontière entre la création humaine et artificielle.
Ainsi, que ce soit dans le domaine de l’art contemporain ou celui de la technologie, la pensée humaine et l’intelligence artificielle sont deux formes de bricolage cognitif. Toutes deux s’appuient sur la recomposition de matériaux préexistants — qu’il s’agisse de mèmes, d’idées, de formes, ou de données — pour produire de nouvelles significations. Cette conception de l’intelligence comme processus de reconfiguration culturelle ouvre des perspectives inédites sur la manière dont les œuvres d’art émergent et comment l’humain, tout comme la machine, s’inscrit dans un continuum de recombinaison perpétuelle.
Protagoras affirmait que « l’homme est la mesure de toute chose ». Aujourd’hui, cette réflexion pourrait être étendue à la mesure de notre propre création, qu’elle soit biologique, culturelle ou numérique. Si l’homme est l’architecte de la civilisation, alors la machine pourrait bien être l’un des outils les plus sophistiqués à sa disposition, une extension de son propre cerveau, capable de manipuler et de réorganiser les structures mêmes de la culture humaine.
The Brain as a Tool of Civilization: Reflections on Human Thought and the Bricolage of Artificial Intelligence
The human brain, brilliantly conceptualized by Gustav Eckstein in The Body Has a Head, is not simply an organ dedicated to abstract contemplation, detached from the real world. It is above all a central biological tool, a crucial cog in the body’s machinery, comparable to the heart or lungs, whose primary function is to ensure the organism’s survival. This analogy with more « physiological » organs underscores how our brain is primarily a survival instrument, designed to meet the individual’s immediate needs.
However, as human societies have become more complex, the brain has demonstrated an extraordinary capacity for adaptation, assuming functions far beyond its initial biological role. It has learned to read, write, create works of art, and manipulate complex instruments like the piano — activities that seem far less related to survival imperatives and more to the building of a collective culture. This transition illustrates a fascinating phenomenon: how an organ shaped by millions of years of evolution to manage hunting, gathering, or protection could diversify to the point of handling abstract functions like mathematics or musical composition?
This cognitive flexibility raises the question: could civilization be seen as a gigantic « diversion » of the brain’s original functions? From a structure initially designed for survival, humans have managed to redirect their brain towards entirely new objectives — sociocultural and political ones. Whether through the mediation of art, the creation of ideologies, or the design of cultural artifacts, the evolution of the brain has increasingly distanced itself from its basic functions. In this sense, could the evolution of our brain be seen less as a process of natural survival and more as a response to the cultural dynamics we have constructed? This transition from biological survival to cultural construction may well be one of the most astonishing characteristics of the human species.
This hypothesis also aligns with the concept of memes, introduced by Richard Dawkins in The Selfish Gene. According to Dawkins, memes are cultural units — forms of thought or behavior, analogous to biological genes — that spread and evolve in human minds. If genes allow the transmission of biological information, memes ensure the transmission of ideas, artistic concepts, styles, and symbols. In this sense, memes are the building blocks of human culture, and they exist only in the human mind. This idea invites us to reconsider the nature of individual thought as a partial manifestation of a collective consciousness, where memes, like pieces of a kaleidoscope, assemble to form coherent but always provisional patterns.
If we apply this perspective to contemporary art, we could see each work not as a creation ex nihilo, but as a recombination of cultural memes, a process in which the artist plays the role of a bricoleur. This term, borrowed from Claude Lévi-Strauss, describes humans as skilled manipulators of symbols, images, and materials. The artist, like Homo faber, uses their material environment to redefine and reinterpret the fragments of a given culture, creating new forms that reflect both individual intentions and broader social dynamics. This ability to assemble, deconstruct, and rearrange cultural elements makes the artist a true architect of collective thought, exploiting the memetic materials available in their intellectual and creative environment.
The idea that human intelligence relies on such a process of bricolage is reinforced by recent discoveries in neuroscience. The FOXP2 gene, essential for language development, is one of the biological structures that enable humans to articulate complex ideas. Language, whether through speech or writing, thus becomes a bridge between biology and culture. Specific areas of the brain’s left hemisphere, such as Broca’s area and Wernicke’s area, are responsible for syntax, grammar, and meaning, and they have evolved to process these linguistic functions. By evolving far beyond their primary survival tasks, these brain regions have allowed humans to conceptualize abstract systems, such as art or philosophy, which constitute the pillars of contemporary civilization.
Iain McGilchrist, in his research on hemispheric specialization, deepens this analysis by revealing an even more complex functional division within the human brain. The left hemisphere, the one concerned with language and social imperatives, contrasts with the right hemisphere, which is more intuitive and preoccupied with existential and emotional questions. This distinction highlights a constant tension between long-term individual needs, often existential, and immediate cultural imperatives. For contemporary artists, this opposition manifests in the balance between creative intuition, often irrational, and the formal structures imposed by culture, art history, and the market. This dialectic between rationality and intuition plays a crucial role in how artists conceive and present their works, underscoring the reciprocal influence between biology, culture, and artistic production.
If we conceive of human intelligence as a process of cultural bricolage, the same can be said for artificial intelligence (AI) systems like ChatGPT. Unlike biological organisms subjected to evolutionary pressures, AIs are not constrained by the same survival imperatives. However, they operate on a similar principle of continuous reorganization and adaptation, but through the analysis and manipulation of massive linguistic data. Just as humans assemble cultural memes to generate new meanings, AIs, particularly in the field of contemporary art, can be seen as participating in a similar process of recombining forms, ideas, and concepts.
Far from being mere imitators, artificial intelligence systems could be considered active agents in the creation of new forms of thought. Although they lack biological experience, they reorganize fragments of cultural data in a way that mimics conscious thought processes, allowing them to participate in the production of new works or artistic concepts. This ability to simulate, or even co-create with humans, brings to light the question of the boundary between human and artificial creation.
Thus, whether in the realm of contemporary art or technology, human thought and artificial intelligence are two forms of cognitive bricolage. Both rely on the recomposition of preexisting materials — whether memes, ideas, forms, or data — to produce new meanings. This conception of intelligence as a process of cultural reconfiguration opens up new perspectives on how artworks emerge and how both humans and machines fit into a continuum of perpetual recombination.
Protagoras asserted that « man is the measure of all things. » Today, this reflection could be extended to the measure of our own creation, whether biological, cultural, or digital. If man is the architect of civilization, then the machine may well be one of the most sophisticated tools at his disposal, an extension of his own brain, capable of manipulating and reorganizing the very structures of human culture.The Brain as a Tool of Civilization: Reflections on Human Thought and the Bricolage of Artificial Intelligence
