Gauchet’s other collaborative works included those written with his partner Gladys Swain, who introduced him to the field of psychiatry and anti-psychiatry. During his collaboration with Swain, he completed critical reviews of La Société contre l’État, recherches d’anthropologie politique by Clastres (with Gauchet’s review appearing in October 1974 in Les Éditions de Minuit) and of L’Histoire de la folie à l’âge classique by Michel Foucault. In April 1980, Gauchet published his first book, co-written with Gladys Swain, La Pratique de l'esprit humain(see synopsis below).
