Many macro-sociologists have insufficient understanding of the roots of human motivation and this seriously hampers the effort to build theoretical models of society, social organisations and social change. The aim of this work is to remedy this deficiency. In this book, a model of motivation is constructed in order to demonstrate how it can improve our understanding of society. The aim here is an integration of concepts from psychology and sociology. Furthermore, it is the aim to clearly demonstrate that such a model adds new insights to our understanding of society. It can enrich key concepts used for analysis of meso- and macro-level phenomena. The author argues that the model of motivation can increase our understanding of, on the macro-level, the history of the state and, on the meso-level, dynamics in organisations.
