Summary

This lecture by Galuzzi L. provides a detailed analysis of Jacques Lacan’s text ‘La science et la vérité’ (Science and Truth). The speaker begins by contextualizing the text as the first session of Lacan’s Seminar XIII, ‘The Object in Psychoanalysis’, and notes that it was originally written for publication. The lecture emphasizes Lacan’s argument that psychoanalysis deals with a divided subject, the ‘spaltung’, and that this subject is not the same as the ego. Galuzzi highlights the influence of Alexandre Koyré on Lacan, particularly Koyré’s anti-positivist history of science and the idea of a rupture between ancient and modern science. The speaker explains how modern science, through mathematization and geometrization, attempts to formalize everything, but Lacan argues that there is always an impossible real that escapes formalization. The lecture discusses the relationship between psychoanalysis and science, noting that while psychoanalysis is not a science in the same way as physics, it uses formalization (like the L-scheme) to account for what cannot be formalized. The speaker also touches on Descartes’ cogito and its relevance to the subject of psychoanalysis. The lecture concludes with a discussion of causality, contrasting the scientific notion of cause with the psychoanalytic concept of cause as rooted in the real.

Value of the Information & Strength of the Argument

The lecture provides a valuable and in-depth interpretation of Lacan’s complex text, making it accessible to students. The argumentation is solid, as the speaker carefully explains each concept and connects it to Lacan’s broader work, such as Seminar XI. The use of examples, like the cashier at the supermarket, helps illustrate abstract ideas. The speaker also engages with questions from the audience, clarifying points about causality and the subject. However, the lecture is primarily expository and does not critically evaluate Lacan’s ideas or present alternative perspectives.
