The Epilogue reflects on various interpretations and aspects of justice interwoven in the contributions to this book. Against the baseline of what is considered in the United Nations as “justice”, the text addresses first Artificial Intelligence, then goes into spiritual justice, and, finally, focuses on the secular justice as a part of its administration and delivery in Member States of the United Nations. After reflecting on these “Heavens-to-Earth” interpretations of justice, the authors formulate recommendations involving a “common language of justice.” With it the United Nations—a global ecumenical organization—celebrating its seventy-fifth anniversary may respond to the challenges involved in the implementation of the 2030 United Nations Sustainable Development Agenda and beyond, as far as democracy and the rule of law are concerned. In this regard, at the domestic and international levels the coronavirus pandemic opened a new legal scenario (“the Day After”). At its heart is “Peace, Justice and Strong Institutions”—the cross-cutting goal of the 2030 Agenda.
