Institutional psychotherapy is a therapeutic method which emerged during the Second World War. At the time, many patients, suffering from psychiatric disturbances, died of hunger in asylums. Such psychiatrists as François Tosquelles, Lucien Bonnafé and Hélène Chaigneau thus considered that psychiatric institutions were sick, and it was necessary to treat them. They transformed the clinic of Saint-Alban in Lozère into an open hospital, thought-out as an intrinsic tool for care. Its “members” farmed the land of the neighbouring village, helped with cooking and ran a printing shop. This method stands as a critical moment for society in its entirety. It should now “walk on both its legs”: its Karl Marx leg and its Sigmund Freud leg. Politics and psychoanalysis. Can this method be applied to cultural institutions for them to be more creative, self-critical and welcoming ?
