This is a guide to the key figures in the Philosophy of Science from Plato and Aristotle through to Popper, Puttnam and Cartwright. As a discipline, the philosophy of science is as old as philosophy itself. "Philosophy of Science: The Key Thinkers" offers a comprehensive historical overview of this fascinating field. Twelve specially commissioned essays introduce and explore the contributions of those philosophers who have shaped the subject and the central issues and arguments therein. All the great philosophers from Plato and Aristotle to the present day have been philosophers of science. However, this book concentrates on modern philosophy of science, starting in the nineteenth century and offering coverage of all the leading thinkers in the field including Whewell, Mill, Reichenbach, Carnap, Quine, Popper, Feyerabend, Putnam, Hacking, Cartwright and many more. Crucially the book demonstrates how the ideas and arguments of these key thinkers have contributed to our understanding of such central issues as experience and necessity, conventionalism, logical empiricism, induction and falsification, the sociology of science, and realism. Ideal for undergraduate students, the book lays the necessary foundations for a complete and thorough understanding of this fascinating subject. "The Key Thinkers" series is aimed at undergraduate students and offers clear, concise and accessible edited guides to the key thinkers in each of the central topics in philosophy. Each book offers a comprehensive overview of the major thinkers who have contributed to the historical development of a key area of philosophy, providing a survey of their major works and the evolution of the central ideas in that area.
