Karine Chemla is currently Senior Researcher at the French National Center for Scientific Research (CNRS), in the research group SPHERE. Her interest is in the history of mathematics in ancient China within the context of a world history. She also researches modern European mathematics. She focuses, from a historical anthropology viewpoint, on the relationship between mathematics and the various cultures in the context of which it is practiced and cultivated. Chemla published, with Guo Shuchun, Les neuf chapitres (2004). She edited The History of Mathematical Proof in Ancient Traditions (2012), and co-edited with J. Virbel Texts, Textual acts and the History of Science (2015). Since 2011, she works with Agathe Keller and Christine Proust on the ERC project "Mathematical Sciences in the Ancient World" (SAW).
Renaud Chorlay was trained in the social sciences at Sciences-Po Paris, and in mathematics and history of mathematics at Paris Diderot University. He works in the teacher-training department of Paris Sorbonne University. His main research field is the history of mathematics in the modern period, with specific interests in qualitative analysis, topology and differential geometry. He also works on the connections between history of mathematics and teaching of mathematics, either in the classroom, in teacher-training, or in theoretical didactics.
David Rabouin is a Senior Research Fellow (CR1) at the French National Center for Scientific Research (CNRS), in the research group SPHERE. His interest is in the history of philosophy and mathematics in early Modern Times, with special focus on Descartes and Leibniz. He also works in contemporary French Philosophy.

Generality is a key value in scientific discourses and practices. Throughout history, it has received a variety of meanings and of uses. This collection of original essays aims to inquire into this diversity. Through case studies taken from the history of mathematics, physics and the life sciences, the book provides evidence of different ways of understanding the general in various contexts. It aims at showing how collectives have valued generality and how they have worked with specific types of "general" entities, procedures, and arguments.
The books connects history and philosophy of mathematics and the sciences at the intersection of two of the most fruitful contemporary lines of research: historical epistemology, in which values (e.g. "objectivity", "accuracy") are studied from a historical viewpoint; and the philosophy of scientific practice, in which conceptual developments are seen as embedded in networks of social, instrumental, and textual practices. Each chapter provides a self-contained case-study, with a clear exposition of the scientific content at stake. The collection covers a wide range of scientific domains - with an emphasis on mathematics - and historical periods. It thus allows a comparative perspective which suggests a non-linear pattern for a history of generality. The introductory chapter spells out the key issues and points to the connections between the chapters.
