"X". Calle Alcalá, Madrid. Photograph by Ana M. Martín Solar. With the evocative title “Once Again, the Mystery”, the Argentine psychoanalyst Mariano Horenstein poses the equally enigmatic question: How do we listen to the language of sexuality today? Through an exploration of the relationship between language and psychoanalysis and the historical transformation of the clinical paradigms that have shaped psychoanalytic listening to date: hysteria, in its origins, with its enigmatic language surrounded by silences, which inaugurated the analytical device; psychosis, which after the Second World War led to the expansion of the field, forcing us to give voice and testimony where the absence of repression predominated; the author shows us the trans clinic as a new paradigm that is currently emerging, not only because it requires the analyst to be heard, but also because it bursts onto the scene with its own voice and avatars of inclusive language, directly challenging psychoanalytic theory and practice, and thus bringing sexuality back to the centre of the psychoanalytic stage and debate. In 2022, “Once Again, the Mystery” won the biennial Carolina Zamora Prize awarded by the Asociación Psicoanalítica de Madrid, which recognised the author by inviting him to participate as one of the main speakers at the seventh Meeting of Spanish-speaking Psychoanalysts in 2024.
