Abstract
This article surveys the recently established field of enquiry called 'development ethics' - that is, ethical enquiry into the normative basis of socio-economic development. This covers two levels of enquiry. First, it involves enquiry into the nature of human well-being and the social norms within which the conditions of well-being should be promoted, and includes consideration of both the means and the ends of development. Second, it involves the ethical basis of the wider global framework within which the development of countries takes place. This covers both the normative basis of international relations and the global relations between individuals in different parts of the world as expressed in the idea of global responsibility
