Dr. Nimi Wariboko, Chair, Executive Committee, is the Walter G. Muelder Professor of Social Ethics at Boston University School of Theology. He holds a PhD in Ethics (Suma Cum Laude) from Princeton Theological Seminary, an MBA in Finance and Accounting from Columbia University in New York City, and a B.Sc. (Economics, first class honors) from University of Port Harcourt, Nigeria. A lively transdisciplinary thinker, Dr. Wariboko loves to unfold, refold, enfold, and energize past and present ideas and hopes in relation to the possibilities of future human flourishing. The five pillars of his scholarship are economic ethics, Christian social ethics, African social traditions, Pentecostal studies, and philosophical theology. The structure of this creative body of work, which is characterized by rigorous interweaving of original insights from each of these fields, is mapped out by the following five central titles. The Principle of Excellence: A Framework for Social Ethics presents social ethics as action-provoking-and-guiding theories of praxis and actualization of potentialities for a more flourishing, inclusive, and creatively reconciled society; the focus of God and Money: A Theology of Money in a Globalizing World is a call for an alternative, inclusive global monetary system that can better support developing economies; Ethics and Time: Ethos of Temporal Orientation in Politics and Religion of the Niger Delta explores the emancipatory core of African culture; The Pentecostal Principle: Ethical Methodology in New Spirit develops a pneumatological methodology of ethics for public policies in pluralistic communities that are open to God’s Spirit; and Economics in Spirit and Truth: A Moral Philosophy of Finance situates a social justice-oriented “care of the soul” at the intersection of radical continental philosophy, economics, and politics to craft an ethics of antifragility and potent freedom that might counter the fragilities unleashed against our socio-economic fabric by late capitalism or global finance capital.
