A Realist Theory of Science is one of the few books that have changed our understanding of the philosophy of science. In this analysis of the natural sciences, with a particular focus on the experimental process itself, Roy Bhaskar provides a definitive critique of the traditional, positivist conception of science and stakes out an alternative, realist position. Since it original publication in 1975, a movement known as ‘Critical Realism’, which is both intellectually diverse and international in scope, has developed on the basis of key concepts outlined in the text. The book has been hailed in many quarters as a ‘Copernican Revolution’ in the study of the nature of science, and the implications of its account have been far-reaching for many fields of the humanities and social sciences.

Following on from Roy Bhaskar’s first two books, A Realist Theory of Science and The Possibility of Naturalism, Scientific Realism and Human Emancipation, establishes the conception of social science as explanatory—and thence emancipatory—critique. Scientific Realism and Human Emancipation starts from an assessment of the impasse of contemporary accounts of science as stemming from an incomplete critique of positivism. It then proceeds to a systematic exposition of scientific realism in the form of transcendental realism, highlighting a conception of science as explanatory of a structured, differentiated and changing world. Turning to the social domain, the book argues for a view of the social order as conditioned by, and emergent from, nature. Advocating a critical naturalism, the author shows how the transformational model of social activity together with the conception of social science as explanatory critique which it entails, resolves the divisions and dualisms besetting orthodox social and normative theory: between society and the individual, structure and agency, meaning and behavior, mind and body, reason and cause, fact and value, and theory and practice. The book then goes on to discuss the emancipatory implications of social science and sketches the nature of the depth investigation characteristically entailed. In the highly innovative third part of the book Roy Bhaskar completes his critique of positivism by developing a theory of philosophical discourse and ideology, on the basis of the transcendental realism and critical naturalism already developed, showing how positivism functions as a restrictive ideology of and for science and other social practices.

Provides a spirited defence of anti-realism in philosophy of science. Shows the historical evidence and logical challenges facing scientific realism.

This introduction to the philosophy of social science provides an original conception of the task and nature of social inquiry. Peter Manicas discusses the role of causality seen in the physical sciences and offers a reassessment of the problem of explanation from a realist perspective. He argues that the fundamental goal of theory in both the natural and social sciences is not, contrary to widespread opinion, prediction and control, or the explanation of events (including behaviour). Instead, theory aims to provide an understanding of the processes which, together, produce the contingent outcomes of experience. Offering a host of concrete illustrations and examples of critical ideas and issues, this accessible book will be of interest to students of the philosophy of social science, and social scientists from a range of disciplines.

First Published in 2008. Now acknowledged as a classic in the philosophy of science, A Realist Theory of Science is one of the very few books which has transformed not only our understanding of science, but that of the nature of the world it studies. Since its original publication in 1975, the book has inspired the multi-disciplinary and international movement of thought known as "critical realism"; and its ideas have been influential across the whole spectrum of the sciences, arts and humanities and in a diverse array of social practices and professions. In this book, Roy Bhaskar sets out to revindicate ontology, critiquing the reduction of being in favor of knowledge, which he calls the "epistemic fallacy". Employing a transcendental argument from the nature of experimental activity, he establishes a critique of the dominant positivist and neo-Kantian traditions in the philosophy of science, developing a new ontology in which concepts of structure, difference and change come to the fore. Then, analyzing the nature of scientific discovery and development, he shows how, against both the empiricist and rationalist traditions, science can come to have a posteriori knowledge of natural necessity. The resultant position, which the author characterizes as transcendental realism, has the power to resolve many traditional philosophical problems, such as the problem of induction. At the same time it lays the basis for radically new accounts of social science, ethics and the project of human emancipation. A new introduction to this edition by Mervyn Hartwig decribes the significance of A Realist Theory of Science throughout the humanities world, and offers an expert critique of its content.

Scientific realism is the view that our best scientific theories give approximately true descriptions of both observable and unobservable aspects of a mind-independent world. Debates between realists and their critics are at the very heart of the philosophy of science. Anjan Chakravartty traces the contemporary evolution of realism by examining the most promising strategies adopted by its proponents in response to the forceful challenges of antirealist sceptics, resulting in a positive proposal for scientific realism today. He examines the core principles of the realist position, and sheds light on topics including the varieties of metaphysical commitment required, and the nature of the conflict between realism and its empiricist rivals. By illuminating the connections between realist interpretations of scientific knowledge and the metaphysical foundations supporting them, his book offers a compelling vision of how realism can provide an internally consistent and coherent account of scientific knowledge.
