This chapter investigates the different senses in which the term 'development' is used. 'Development' is used in three main senses: a vision or measure of a desirable society; a historical process of social change; and deliberate efforts at improvement by development agencies. The variety of competing overall views on development can be organized into three groups according to how they see development relating to capitalism: through, against, or in the context of capitalism. The first two of these groups of views are labelled Market economics and Structuralism. A third group of views, pragmatic rather than theoretical, is termed Interventionism and concentrates on how to achieve development. Finally, there are those who reject all these views as versions of 'mainstream' development. They seek alternatives, either an alternative form of development or rejecting the development concept entirely.
