«Liberté, Égalité, Fraternité». The French revolutionaries had many flaws and unacceptable methods, but they understood that freedom and equality are inextricably linked. With regard to fraternity, we enter the private sphere perhaps, but it is certainly a next step and it is no coincidence that it is mentioned last. Those ideals are still far from our grasp as inequalities in some areas of the planet are still growing. In fact, a part of the global population is unable to participate in social, cultural, political and economic life and is thereby powerless to make a contribution to global development. For this reason, Goal 10 of the 2030 agenda in the United Nations aims to reduce inequalities not only between different countries, but also within the same nations. This was discussed at the Foundation on 25 June in the seminar coordinated by Professor Giuseppe Nesi, Italian jurist and professor, former dean of the Faculty of Law of the University of Trento and legal advisor to the president of the United Nations General Assembly in its 65th session, from 2010 to 2011. Nesi, a recently elected member of the UN International Law Commission (mandate 2023-2027), coordinated an interesting seminar, attended by Angelica Bonfanti, professor of international law at the State University of Milan and Gianluca Alberini, minister plenipotentiary, at the Ministry of Foreign Affairs and International Cooperation. In order to provide further food for thought, we report a summary of the interventions that animated the discussion in this special issue of our magazine.
