On September 23rd, 2020 one of the moments of the Jornada. EBP-SP, "Subversions" took place. We share the "Oriented Reading" of Lacan's text, "Subversion of the subject and dialectics of desire in the Freudian unconscious", presented by Sérgio Laia, subverting, in his development, the "discipline of commentary". Instead, he brings us a very refined and fruitful elaboration on jouissance and its articulation with the S of barred A, taken from this 1960 text. The passages chosen for commentary (33 paragraphs) "are related to a very important moment of my analysis", an analysis which led to its conclusion and to his appointment as AE in 2018.
