Troubled times require not only radically new ideas, but also new approaches to the fundamental principles of community resilience: sharing, generosity, compassion. That’s the principle underlying ServiceSpace founder Nipun Mehta’s notion of “giftivism”, which states that fundamental social change will require that we design for generosity, not self-interest. In this talk at TEDxBerkeley, Mehta explores his vision of “radically generous acts that change the world” and cites inspiring examples of giftivism in action.
