Social progress can be seen as a goal to be achieved or as a threat from which it is appropriate to depart. In recent decades we have witnessed the decline of global poverty and the arrival of democracy in many countries, the expansion of health and education programmes, with undeniable improvements in hope and quality of life, but at the same time there is an atmosphere of skepticism about the possibility—and convenience—of inducing social progress such as that achieved by the most developed societies , with its channel of inequality and its environmental costs. Seeking solutions to global problems, the International Panel on Social Progress brought together more than 300 social scientists to explore current challenges and propose ways to improve the main institutions of modern societies. From this collaborative work comes this manifesto – written by Marc Fleurbaey, together with Olivier Bouin, Marie-Laure Salles-Djelic, Ravi Kanbur, Helga Nowotny and Elisa Reis – in which the utopian spirit coexists with pragmatism, in which the pursuit of justice is compatible with the strengthening of key actors, such as the company or the market. The conclusion is simple and at the same time involves enormous complications: a better society is possible but various forces need to be harmonized. To achieve a cultural change of great proportions, a bold mixture of idealism and wisdom is required. That's what this manifesto offers.
