Although most of the critiques to which my work was exposed in the last years are “so-called,” fast denunciations not worthy of a serious reply, some of them do at least raise pertinent questions : which, exactly, is the status of violence in social life, and how can one justify resort to it? Is in our societies a radical social change — not just a revolt but the imposition of a new order – objectively possible? What is materialism today, beyond the usual versions of deconstructionist discursive materialism, Deleuzian “new materialism,” and scientific naturalism? And, last but not least, what immanent role do jokes play in theory?
