    In A Social Ontology of Psychosis, Diego Enrique Londoño-Paredes explores how to interpret and apply the concept of the signifier of the Name-of-the-Father in Lacanian theory, particularly in the context of working with psychosis.

    Londoño proposes a logical framework drawing on the work of Badiou, then traces the historical development of this concept and its implications as a structural necessity for anyone who speaks and engages in discourse. The book opens by exploring set theory, transitioning from nought to one, from the Thing to the object, essential for any presentation. Subsequently, it follows a historical path, examining the evolution of the figure and the signifier of the Father, journeying from ancient Mesopotamian roots through Modernity, touching upon Claudel’s theater and the films of the Coen brothers. Finally, it aligns Searle’s social ontology with Lacan’s discourses, highlighting psychosis as an illustration of being outside discourse, particularly when the Name-of-the-Father is foreclosed. Case material illustrates various ways psychosis manifests without distinct clinical evidence.

    This comprehensive book will be of great interest to practitioners and scholars in psychoanalysis, philosophy, the humanities, and the history of mental health and knowledge.

    “This exceptionally rich book explores the multifaceted role and significance of the father in Lacan’s work. Diego Londoño seamlessly connects logical formulations with socio-cultural reflections and clinical considerations, making this book not only a comprehensive discussion of Lacan’s work but also a reference on how to apply it in contemporary practice.”

    Stijn Vanheule, Ghent University

    “In A Social Ontology of Psychosis, Londoño provides a logical and genealogical account of the function and place of the father in civilization through a careful analysis of the various versions of the father in psychoanalytic theory as developed by Sigmund Freud and Jacques Lacan. His logico-genealogical reading of Lacan’s theory of the Name-of-the-Father provides a contemporary commentary on psychotic subjectivity in civilization in both pathological and non-pathological forms. Moreover, in developing Lacan’s theory of the Name-of-the-Father in relation to logic, set theory, the big Other, language and myth he provides an intriguing response to what may have occurred in Lacan’s 1963 abandoned seminar, The Names of the Father.”
