Where does psychoanalysis stand today? These letters paint a picture of the Freudian field, inseparable, for better or for worse, from the Lacanian effect and the repercussions of his teaching, both in France and abroad. They are signed by psychoanalysts (students or detractors), some of whom were close to him from the beginning, but also by scientists and artists from other backgrounds. One can see here an unexpected form of manifesto, a reminder of Lacanian knowledge that allowed for all kinds of statements and counterarguments, from the most outlandish to the most serious, from the most literary to the most theoretical.
