Internet rend-il bête? by Nicholas Carr

By Nicholas Carr

Essai sur l'influence d'internet sur nos cerveaux.

C'est bien sûr à une révolution procedure et informationnelle que nous assistons avec net. Mais c'est surtout à une révolution dans notre cerveau ! Vous aviez l'habitude de lire tranquillement et de façon linéaire un livre sur lequel vous portiez toute votre cognizance. Cela pouvait durer des heures pendant lesquelles vous, lecteurs, vous immergiez dans le monde singulier d'un auteur, en y mettant toute l. a. focus que vous désiriez. Regardez maintenant ce qui se passe quand vous vous connectez à web. Vous zappez de web page en web page par des liens qui vous promènent ici et là, et pendant ce temps vous êtes aussi bombardés de messages, parfois d'alertes vous informant qu'un mail vient de vous arriver ou qu'une nouvelle récente vient de mettre un web publication ou un website internet (sur un flux RSS) à jour...
Que se passe-t-il alors dans notre esprit ? En quoi cet environnement électronique change-t-il notre état psychological, voire notre comportement social ? Ne serons-nous bientôt plus capables de nous concentrer plus de quelques mins sur un texte ? N'allons-nous pas nous contenter de picorer ici et là quelques bribes (de textes, de vidéos, de messages audio) ? Notre cerveau, incroyablement plastique, s'adapte très vite aux nouvelles applied sciences et à leurs nouvelles tentations... Quels sont les avantages et les inconvénients de ces changements pour notre esprit ?

Nicholas Carr pose ici une query fondamentale : quel monde nouveau l'Homo sapiens vient-il de se forger et y résistera-t-il ? Dans un détour historique passionnant, il nous rappelle que l'homme s'est constamment créé de nouvelles façons de penser. D'abord en inventant l'écriture (Sumer, les hiéroglyphes égyptiens..., et le passage de l. a. tradition orale à l'écrit) puis en faisant évoluer los angeles lecture (devenue silencieuse après des siècles où elle se healthy à voix haute). L'imprimerie lui a fait accomplir un saut nouveau dans l'accès à los angeles connaissance. Et jusqu'à très récemment, l. a. capacité à se concentrer dans los angeles lecture, pour tout apprentissage, a été au cœur de notre mode d'éducation.

Que va-t-il se passer maintenant que des professeurs d'université - même en littérature - ne parviennent plus à faire lire leurs étudiants ( Guerre et Paix, À l. a. recherche du temps perdu... c'est bien trop long). net va-t-il nous rendre bêtes, comme le laissent entendre certaines études scientifiques ? remark les générations futures vont-elles penser ?
