From the late nineteenth century onwards religion gave way to science as the dominant force in society. This led to a questioning of the principle of free will—if the workings of the human mind could be reduced to purely physiological explanations, then what place was there for human agency and self-improvement?

Smith takes an in-depth look at the problem of free will through the prism of different disciplines. Physiology, psychology, philosophy, evolutionary theory, ethics, history and sociology all played a part in the debates that took place. His subtly nuanced navigation through these arguments has much to contribute to our understanding of Victorian and Edwardian science and culture, as well as having relevance to current debates on the role of genes in determining behaviour.

Marshall Edelson identifies the core theory of psychoanalysis and shows how free association and the case study method can provide rational grounds for believing its clinical inferences about the causal role of unconscious sexual fantasies. "Dr. Edelson has committed himself with gusto, persistence and intelligence [to] a spirited defense of psychoanalysis as science—not necessarily as it is, but as it can be in the best of hands as it should be. . . . It is a defense that I hope can resonate strongly in psychoanalytic ranks. It is also a message that I hope would receive a warm reception in that wider intellectual world where ideas matter and where enlightened social policy and cultural cachet are fostered."—Robert Wallerstein, New York Times Book Review

In A Search for Clarity, Jean‑Claude Milner argues that although Jacques Lacan’s writing is notoriously obscure his oeuvre is entirely clear. In a discussion that considers the difference between the esoteric and exoteric works of Plato and Aristotle, Milner argues that Lacan’s oeuvre is to be found in his published writings alone, not his transcribed seminars, and that these published writings contain his official doctrine. Thus, Lacan’s oeuvre is already complete, even though many of his seminars remain unpublished.

According to Milner, Lacan’s fundamental idea is that the subject psychoanalysis works on is the subject of science. Milner suggests that this is a supplement to Alexandre Koyré’s and Alexandre Kojève’s accounts of modern science, for which mathematization and a break from the ancient episteme were key.

A Search for Clarity is the definitive statement on how Lacan viewed the relationship between psychoanalysis and science, and on how Lacan’s thinking evolved as he struggled to draw out the consequences of the equation he posited between psychoanalysis and science. Milner’s work on Lacan has been essential reading in French for decades. This English translation will make his illuminating work accessible to a broader audience.
