Abstract

The nineteenth-century metaphor of a block universe in which science is regarded as a structure consisting of basic building blocks resting on firm foundations is contrasted with the contemporary metaphor of science as a network of relations. The network metaphor challenges the view that one science is more foundational than others and raises questions about whether an all-pervasive unity is desirable or even possible. The unity-disunity issue in psychology and other sciences is discussed with respect to the network and building block metaphors and with respect to three arenas: organizations, methodology, and subject content areas. It is argued that in these three arenas, psychology is no more disunified than biology. There is no basis for the development of a disciplinary inferiority complex based on the belief that the other sciences are unified while psychology remains in the intellectual backwaters of plurality
