For several years Bernard Harcourt and colleagues at The Columbia Center for Contemporary Critical Thought have been running a series of 13/13 seminars. The seminars usually have short essays by participants available online, and now they are being collected on a single site – The 13/13 Essays. Includes the sessions on Foucault, Nietzsche, Critique, Revolution, Praxis, Utopia, Abolition Democracy and the current series on Coöperism.
