Some think that issues to do with scientific method are last century's stale debate; Popper was an advocate of methodology, but Kuhn, Feyerabend, and others are alleged to have brought the debate about its status to an end. The papers in this volume show that issues in methodology are still very much alive. Some of the papers reinvestigate issues in the debate over methodology, while others set out new ways in which the debate has developed in the last decade. The book will be of interest to philosophers and scientists alike in the reassessment it provides of earlier debates about method and current directions of research.

This volume examines Popper’s philosophy by analyzing the criticism of his most popular critics: Thomas Kuhn, Paul Feyerabend and Imre Lakatos. They all followed his rejection of the traditional view of science as inductive. Starting from the assumption that Hume’s criticism of induction is valid, the book explores the central criticism and objections that these three critics have raised. Their objections have met with great success, are significant and deserve paraphrase. One also may consider them reasonable protests against Popper’s high standards rather than fundamental criticisms of his philosophy. The book starts out with a preliminary discussion of some central background material and essentials of Popper’s philosophy. It ends with nutshell representations of the philosophies of Popper. Kuhn, Feyerabend and Lakatos. The middle section of the book presents the connection between these philosophers and explains what their central ideas consists of, what the critical arguments are, how they presented them, and how valid they are. In the process, the author claims that Popper's popular critics used against him arguments that he had invented (and answered) without saying so. They differ from him mainly in that they demanded of all criticism that it should be constructive: do not stop believing a refuted theory unless there is a better alternative to it. Popper hardly ever discussed belief, delegating its study to psychology proper; he usually discussed only objective knowledge, knowledge that is public and thus open to public scrutiny.

What is it to be scientific? Is there such a thing as scientific method? And if so, how might such methods be justified? Robert Nola and Howard Sankey seek to provide answers to these fundamental questions in their exploration of the major recent theories of scientific method. Although for many scientists their understanding of method is something they just pick up in the course of being trained, Nola and Sankey argue that it is possible to be explicit about what this tacit understanding of method is, rather than leave it as some unfathomable mystery. They robustly defend the idea that there is such a thing as scientific method and show how this might be legitimated. This book begins with the question of what methodology might mean and explores the notions of values, rules and principles, before investigating how methodologists have sought to show that our scientific methods are rational. Part 2 of this book sets out some principles of inductive method and examines its alternatives including abduction, IBE, and hypothetico-deductivism. Part 3 introduces probabilistic modes of reasoning, particularly Bayesianism in its various guises, and shows how it is able to give an account of many of the values and rules of method. Part 4 considers the ideas of philosophers who have proposed distinctive theories of method such as Popper, Lakatos, Kuhn and Feyerabend and Part 5 continues this theme by considering philosophers who have proposed naturalised theories of method such as Quine, Laudan and Rescher. This book offers readers a comprehensive introduction to the idea of scientific method and a wide-ranging discussion of how historians of science, philosophers of science and scientists have grappled with the question over the last fifty years.

Philosopher, physicist, and anarchist Paul Feyerabend was one of the most unconventional scholars of his time. His book Against Method has become a modern classic. Yet it is not well known that Feyerabend spent many years working on a philosophy of nature that was intended to comprise three volumes covering the period from the earliest traces of stone age cave paintings to the atomic physics of the 20th century – a project that, as he conveyed in a letter to Imre Lakatos, almost drove him nuts: “Damn the ,Naturphilosophie.” The book’s manuscript was long believed to have been lost. Recently, however, a typescript constituting the first volume of the project was unexpectedly discovered at the University of Konstanz. In this volume Feyerabend explores the significance of myths for the early period of natural philosophy, as well as the transition from Homer’s “aggregate universe” to Parmenides’ uniform ontology. He focuses on the rise of rationalism in Greek antiquity, which he considers a disastrous development, and the associated separation of man from nature. Thus Feyerabend explores the prehistory of science in his familiar polemical and extraordinarily learned manner. The volume contains numerous pictures and drawings by Feyerabend himself. It also contains hitherto unpublished biographical material that will help to round up our overall image of one of the most influential radical philosophers of the twentieth century.

Although Thomas Kuhn and Karl Popper debated the nature of science only once, the legacy of this encounter has dominated intellectual and public discussions on the topic ever since. Kuhn's relativistic vision of science as just another human activity, like art or philosophy, triumphed over Popper's more positivistic belief in revolutionary discoveries and the superiority of scientific provability. Steve Fuller argues that not only has Kuhn's dominance had an adverse impact on the field but both thinkers have been radically misinterpreted in the process.

Popper and After: Four Modern Irrationalists focuses on a tendency in the philosophy of science, of which the leading representatives are Professor Sir Karl Popper, the late Professor Imre Lakatos, and Professors T. S. Kuhn and P. K. Feyerabend. Their philosophy of science is in substance irrationalist. They doubt, or deny outright, that there can be any reason to believe any scientific theory; and a fortiori they doubt or deny, for example, that there has been any accumulation of knowledge in recent centuries. The book is composed of two parts and Part One explains how these writers succeeded in making irrationalism about science acceptable to readers. Part Two explores the intellectual influence that led these writers to embrace irrationalism about science.

Criticism and the History of Science deals with Thomas Kuhn's, Imre Lakatos's and Paul Feyerabend's criticism of Karl Popper's falsificationist conception of science. It argues that this criticism is based on two important methodological problems: the problem that observations and tests statements are fallible and impregnated with theory, and the problem of how to test complex theoretical systems. In order to solve these problems it shows how problematic test statements can be criticised and whole theoretical systems falsified. In this way the falsificationist conception of science is developed and defended in a way making a deeper understanding of science and its history possible.
