Only by putting the climate crisis at the center can the illustrated project The legacy of the Enlightenment is in crisis be renewed. His blind trust in reason and technology is naive in the face of the ecological emergency we are experiencing. Faced with this situation, there are not a few intellectuals who have chosen to seek alternatives to the Enlightenment, often traveling the dangerous paths of anti-rationalism or authoritarianism. However, should we scrap the Enlightenment entirely? Is it perhaps a watertight, immovable, expired project? Can a thought whose objective was the autonomy of the human being be updated, more than two hundred years later? Corine Pelluchon lucidly addresses these questions to relaunch, in a context of eco-social collapse, the critical and emancipatory presuppositions of the original Enlightenment movement, but purging anthropocentrism and adjusting it to the biophysical limits imposed by our planet.
