This very short essay builds on the previous work of Michel Serres; it tries to play some of its concepts (mainly that of Biogée) to better understand the financial crisis. Basically, the assumption is that the 2008 financial crisis is just one epiphenomenon of a disruption of much greater magnitude, that it takes very fast dune analysis of long term of history (from the late Neolithic to the present). Inevitably, in 75 written pages and with great many repetitions, do not sétonner that the text goes straight in the higher spheres and sometimes seem frankly just engaged with the current problems, but at the same time it contains real times dazzling features that allow us to get high at the time.
