Qu’est-ce que l’émergence ( lire aussi tout le dossier sur la complexité) :

Extrait :

L’émergence peut être celle d’un ordre élémentaire dans un chaos sans structure : en rangeant une grosse pile de livres par taille croissante, sur les rayons de la bibliothèque apparaissent —émergent— des séries homogènes d’ouvrages publiés dans une même collection ou par un même éditeur. Autre exemple : des atomes en vrac, ensemencés par un microcristal se rangent et font surgir —émerger— une régularité géométrique parfaite où chaque atome trouve sa place.

Mais l’émergence peut aussi être celle d’un objet finement structuré s’imposant à une confusion initiale : du tas de feuilles en décomposition surgit un champignon inattendu ; des mouvements non coordonnés des molécules à la surface de la terre il y a trois milliards d’années naissent —émergent— les premières formes auto-réplicatrices, qui deviennent plus tard des cellules vivantes, puis des êtres d’une infinie variété…
