Johanna Oksala is Senior Lecturer in Philosophy at the University of Dundee and member of the Centre of Excellence in Political Thought and Conceptual Chance at the University of Jyväskylä. She is the author of Foucault on Freedom and a co-editor of collections of essays on feminist philosophy and ethics.

Michel Foucault was a twentieth-century philosopher of extraordinary talent, a political activist, social theorist, cultural critic and creative historian. He shaped the ways we think today about such controversial issues as power, sexuality, madness and criminality. Johanna Oksala explores the conceptual tools that Foucault gave us for constructing new forms of thinking as well as for smashing old certainties. She offers a lucid account of him as a thinker whose persistent aim was to challenge the self-evidence and seeming inevitability of our current experiences, practices and institutions by showing their historical development and, therefore, contingency. Extracts are taken from the whole range of Foucault's writings - his books, essays, lectures and interviews - including the major works History of Madness,The Order of Things, Discipline and Punish and The History of Sexuality.
