Book excerpt: Closely examining Jacques Lacan's unique mode of engagement with philosophy, Lacan with the Philosophers sheds new light on the interdisciplinary relations between philosophy and psychoanalysis. While highlighting the philosophies fundamental to the study of Lacan’s psychanalysis, Ruth Ronen reveals how Lacan resisted the straightforward use of these works. Lacan’s use of philosophy actually has a startling effect in not only providing exceptional entries into the philosophical texts (of Aristotle, Descartes, Kant and Hegel), but also in exposing the affinity between philosophy and psychoanalysis around shared concepts (including truth, the unconscious, and desire), and at the same time affirming the irreducible difference between the analyst and the philosopher. Inspired by Lacan’s resistance to philosophy, Ruth Ronen addresses Lacan’s use of philosophy to create a fertile moment of exchange. Straddling the fields of philosophy and psychoanalysis with equal emphasis, Lacan with the Philosophers develops a unique interdisciplinary analysis and offers a new perspective on the body of Lacan’s writings.
