• Tangente n°182, p34-35, "Les excès de la corrélation".

Nous allons vers un changement épistémologique majeur. S'en remettre à ce type de calcul traduit un renoncement aux ambitions de la raison moderne, qui liait les phénomènes à leurs causes. Ces ambitions de la raison permettaient d'envisager la prévention, d'agir sur les causes pour changes les effets. Au lieu de cela, on se dirige vers un système de pures corrélations. [...] On ne cherche plus à comprendre l'environnement, on cherche à le prédire. Notre rapport au savoir change, mais aussi notre rapport au monde: on se focalise davantage qu'auparavant sur les risques. "Voir et comprendre" sont supplantés par détecter et prévenir". On passe d'une civilisation du signe, qui était porteur de sens, à une civilisation du signal, qui est une donnée qui ne signifie rien en soi..
