2021 marks exactly half a century since the publication of a book whose importance and depth in diagnosing the problems of late modernity has only increased since it was published. In the field of economic thought The law of entropy and the economic process, the masterpiece of Nicholas Georgescu-Roegen, opened the way to a new perspective in the analysis of economic phenomena such as the bioeconomy or ecological economy. But beyond his scientific contributions and without abandoning the cold objectivity that springs from thermodynamic considerations of the economy, the work of Georgescu Roegen supposed an intellectual shake in the field of culture, ideas and ways of life that accompanied the fossil capitalism. The work of Georgescu Roegen warned of the problem of resource depletion and the thermodynamic unsustainability of an economic system that demands perpetual growth but also confronted us with the moral implications that sooner or later we would have to face if we followed the path we were on. the world has been transiting ever since. What in 1971 was a dangerous future horizon, in 2021 is imposed as the most serious problem that our time has to face.
