This book explores the biography, issues and legacy of French social theorist and philosopher Michel Foucault. Arguably, Foucault was the greatest scholar of the 20th century and has left a huge legacy. The issues that emanate from his work will be discussed and evaluated especially in relation to applied social science as a discipline of study as well as empirical examples from contemporary social research. In particular, the book explores examples drawing from helping professions to illuminate the legacy of Michel Foucault and his influential concepts and theories.
