This study offers a new interpretation of the emergence of scientific psychology and sociology in late-nineteenth-century France. Focusing on their relationship with the philosophy taught in the French education system, the author shows the profound impact on the individuals most responsible for the introduction of the human sciences into the French university - particularly Theodule Ribot, Alfred Espinas, Pierre Janet, and Emile Durkheim. Philosophers helped shape the human sciences by their criticisms of conceptual and methodological problems in the emerging disciplines. The human sciences that emerged were less reductionist and more methodologically sound than they would have been without the vigorous debate with philosophy. This influence is the eclectic legacy of academic philosophy to the human sciences in France.

For much of the twentieth century, French intellectual life was dominated by theoreticians and historians of mentalité. Traditionally, the study of the mind and of its limits and capabilities was the domain of philosophy, however in the first decades of the twentieth century practitioners of the emergent human and social sciences were increasingly competing with philosophers in this field: ethnologists, sociologists, psychologists and historians of science were all claiming to study 'how people think'. Scholars, including Gaston Bachelard, Georges Canguilhem, Léon Brunschvicg, Lucien Lévy-Bruhl, Lucien Febvre, Abel Rey, Alexandre Koyré and Hélène Metzger were all investigating the mind historically and participating in shared research projects. Yet, as they have since been appropriated by the different disciplines, literature on their findings has so far failed to recognise the connections between their research and their importance in intellectual history. In this exemplary book, Cristina Chimisso reconstructs the world of these intellectuals and the key debates in the philosophy of mind, particularly between those who studied specific mentalities by employing prevalently historical and philological methods, and those who thought it possible to write a history of the mind, outlining the evolution of ways of thinking that had produced the modern mentality. Dr Chimisso situates the key French scholars in their historical context and shows how their ideas and agendas were indissolubly linked with their social and institutional positions, such as their political and religious allegiances, their status in academia, and their familial situation. The author employs a vast range of original research, using philosophical and scientific texts as well as archive documents, correspondence and seminar minutes from the period covered, to recreate the milieu in which these relatively neglected scholars made advances in the history of philosophy and science, and produced
