Name- of the- Father in Lacanian Psychoanalysis and in Jewish Tradition Abstract This paper will focus on the way the Jewish theological idea of the hidden name of G-d and its verbal expression in the Bible can shed new light on two of the most enigmatic notions of the Jacques Lacan’s school of psychoanalysis, namely the ‘Name-of- the- Father’ and the etiology of psychosis. As Lacan unabashedly said: “Maybe in ten years, people will understand my work” (Skinner, 2014). Indeed, his sentiment feels true. His work is complex: full of paradoxes, associations, linguistic, theological, and anthropological references and literary allusions. After developing his theory of language and psychosis, Lacan broke ties with the psychiatric establishment and founded a new school of theory and practice. Like Freud, Lacan challenged the classic western tradition of evidence- based diagnostic practices and continued to develop his unique approach to understanding the human psychic reality. Many clinicians find it difficult to apply Lacan’s work to their practices. His concepts are perceived to be extremely abstract and removed from clinical practice. This paper reflects our attempt to close this gap and build the bridge between theory and practice, while elaborating on the Jewish theological doctrine of the Name of the Divine and the function of language as a tool to connect to Divinity.
