This article examines the contribution of one Islamic scholar, Fetullah Gülen to the debate about the meaning and practice of responsibility. It analyses Gülen’s thinking in terms of three inter-connected modes of responsibility: relational accountability, moral agency and liability. This view of responsibility is contrasted with major western philosophers such as Levinas, Buber and Jonas, Islamic tradition and the major views about corporate responsibility, including stakeholder theory. The role of dialogue in embodying the three modes of responsibility is then analysed. (...) The social responsibility practice of business leaders who are part of Gülen’s Hizmet Movement is briefly surveyed to illustrate the embodiment of responsibility. This focuses on the contribution of business to education and peace building, and includes the example of Zaman Daily. (shrink)
