Science and Hypothesis is a classic text in history and philosophy of science. Widely popular since its original publication in 1902, this first new translation of the work in over a century features unpublished material missing from earlier editions.

Addressing errors introduced by Greenstreet and Halsted in their early 20th-century translations, it incorporates all the changes, corrections and additions Poincaré made over the years. Taking care to update the writing for a modern audience, Poincaré’s ideas and arguments on the role of hypotheses in mathematics and in science become clearer and closer to his original meaning, while David J. Stump’s introduction gives fresh insights into Poincaré’s philosophy of science. By approaching Science and Hypothesis from a contemporary perspective, it presents a better understanding of Poincare’s hierarchy of the sciences, with arithmetic as the foundation, geometry as the science of space, then mechanics and the rest of physics.

For philosophers of science and scientists working on problems of space, time and relativity, this is a much needed translation of a ground-breaking work which demonstrates why Poincaré is still relevant today.

Frappier et al. have done an excellent job of bringing back—so to speak—Poincaré’s masterpiece of philosophical and scientific thought. * Metascience *
I heartily applaud David Stump, Melanie Frappier and Andrea Smith for this splendid new edition of Poincaré's Science and Hypothesis. By bringing language and terminology up-to-date and providing new insights they have ensured that the book can once again reach the wide audience originally reached by Poincaré. At the same time, they give us a fascinating glimpse into the state of philosophy on the eve of the 20th-century revolutions in mathematical and scientific thought. -- John Stillwell, Professor of Mathematics, University of San Francisco, USA
Poincaré’s essays on science and mathematics retain their importance after over a century because he stood back from the day-to-day tasks to reflect on what it is to do research, the kinds of questions that can be asked, and the kind of answers one might get. This new translation displays the lucidity of his thought, and David Stump’s Foreword brings out the depths that lie beneath Poincaré’s urbane style. There is new material here, too, and altogether this book is a fresh presentation of Poincaré as an intellectual companion for the twenty-first century. -- Jeremy Gray, Emeritus Professor, The Open University, UK
This updated and corrected translation of Science and Hypothesis is an essential addition to both personal and institutional libraries. Scholars who prefer to read Poincaré in English, as well as general readers of philosophy of science, will appreciate this version, which was produced by a team of three translators/editors. In addition to corrections, the volume includes an additional chapter 14: a paper written in 1906 and added to French editions of 1917, but not included in any prior English translations. Happy reading! -- Janet Folina, Professor of Philosophy, Macalester College, USA
This book is a must-read in the foundations of mathematics and physics. For the beginner, the accurate translation of Poincaré’s masterpiece is an excellent introduction to the subject, full of verve and good humor. For the expert, the brilliant foreword gives a lucid account of the major interpretations of Poincaré’s work. -- Gerhard Heinzmann, President of the International Academy of Philosophy of Science (AIPS), Bruxelles, Université de Lorraine/CNRS, France
This is the edition of Poincaré’s Science and Hypothesis English-speaking scholars will henceforth want to use in their teaching and research. The translators have made it more readable without sacrificing accuracy, and their helpful notes, references, and explanations reflect the most recent scholarship on this important philosopher and mathematician. -- Warren Schmaus, Professor of Philosophy, Illinois Institute of Technology, USA
It was certainly about time a new translation of Poincaré’s great classic came out. The translators have done a thorough job comparing first and subsequent editions and updating the language. This volume is to become the definitive English edition of Science and Hypothesis. -- María de Paz, Department of Philosophy, Universidad de Sevilla, Spain
Poincare’s Science and Hypothesis offers one of the deepest and yet most accessible investigations into the nature of science, constituting one of the most significant works in philosophy of science of the 20th century. This excellent new translation and introduction to Poincare’s philosophy offers an invaluable resource for anyone interested in the scientific method and the nature of scientific knowledge. -- Milena Ivanova, University of Cambridge, UK
