The aim of this textbook is to explore the enlightening potential of Michel Foucault's power analysis for a critical theory and practice of social work, and to connect it for the first time with current discussions on social exclusion. Foucault's analyses are subjected to critical examination: the strengths and limitations of his approaches are highlighted. At the same time, the book also addresses the "whole" Foucault, meaning the breaks and contradictions that arise from engaging with his analyses. In this regard, the book has a dual purpose: it provides students of social work with access to Foucault's thinking in its relevance to social work. Additionally, it makes a substantial contribution to the development of social work theory.
