‘The truth will set you free' is a maxim central to both theories and practices of resistance. Nonetheless, it is a claim that has come under fire from an array of critical perspectives in the second half of the 20th century. Iain MacKenzie analyses two of the most compelling of these perspectives: the poststructuralist politics of truth formulated by Michel Foucault and Gilles Deleuze and the alternative post-foundational account of truth and militancy developed by Alain Badiou. He argues that a critically oriented version of poststructuralism provides both an understanding of the deeply entwined nature of truth and power and a compelling account of the creative practices that may sustain resistance.
