Bringing diverse communities into actionable dialogues in a free and secure space enables a shared understanding of diplomativity as an enduring human source of self-affirmation and empowerment through mutuality with nature and other humans. The base of such an approach is in transformative scientific research into diplomacy. Throughout the recorded history of human connections, there were similar systemic transitions that led to the very word "diplomacy" and to the processes, institutional structures, and specialized profession known today. A unique human feature of grasping mutuality as the constituting relation of reality and enacting species mutuality in this universal order is therefore named "diplomativity." Educational frameworks are developed to foster the situational rediscovery of diplomativity and mutuality, encouraging cooperation for the betterment of all. Principles of empathy, active listening, and joint problem-solving are embedded as an integrated whole. Using immersive technologies facilitates hacking back diplomativity into humanity. Recovering it in meaningful arrangements is needed today more than ever. For the first time, it is feasible on a global scale among diverse collectives. The Foundation Dositej-Pupin-Tesla was established for that purpose and is dedicated to genuinely serving it.
