An interview with Michel Foucault in 1979 that was never published during his lifetime and was recently rediscovered in the archives. The interview, appearing for the first time in English and in its complete form, marks one of Foucault’s final public discussions of the contentious topic of the Iranian Revolution. In particular, Foucault clarifies what he means by “political spirituality” and addresses the respective relations between religion, revolution, and self-transformation.
