Originally published in French in 1972, ‘Psychoanalysis and Transversality’ gathers all the articles that Felix Guattari wrote between 1955 and 1971. It provides a fascinating account of his intellectual and political itinerary before ‘Anti-Oedipus: Capitalism and Schizophrenia’ (1972), the ground-breaking book he wrote with Gilles Deleuze, propelled him to the forefront of contemporary French philosophy.
