How does science work? Does it tell us what the world is "really" like? What makes it different from other ways of understanding the universe? In Theory and Reality , Peter Godfrey-Smith addresses these questions by taking the reader on a grand tour of one hundred years of debate about science. The result is a completely accessible introduction to the main themes of the philosophy of science. Intended for undergraduates and general readers with no prior background in philosophy, Theory and (...) Reality covers logical positivism the problems of induction and confirmation Karl Popper's theory of science Thomas Kuhn and "scientific revolutions" the views of Imre Lakatos, Larry Laudan, and Paul Feyerabend and challenges to the field from sociology of science, feminism, and science studies. The book then looks in more detail at some specific problems and theories, including scientific realism, the theory-ladeness of observation, scientific explanation, and Bayesianism. Finally, Godfrey-Smith defends a form of philosophical naturalism as the best way to solve the main problems in the field. Throughout the text he points out connections between philosophical debates and wider discussions about science in recent decades, such as the infamous "science wars." Examples and asides engage the beginning student a glossary of terms explains key concepts and suggestions for further reading are included at the end of each chapter. However, this is a textbook that doesn't feel like a textbook because it captures the historical drama of changes in how science has been conceived over the last one hundred years. Like no other text in this field, Theory and Reality combines a survey of recent history of the philosophy of science with current key debates in language that any beginning scholar or critical reader can follow.

The orphaned son of an Anglican clergyman, David Hartley was originally destined for holy orders. Declining to subscribe to the Thirty-Nine Articles, he turned to medicine and science yet remained a religious believer. This, his most significant work, provides a rigorous analysis of human nature, blending philosophy, psychology and theology. First published in two volumes in 1749, Observations on Man is notable for being based on the doctrine of the association of ideas. It greatly influenced scientists, theologians, social reformers and (...) poets: Samuel Taylor Coleridge, who named his eldest son after Hartley, had his portrait painted while holding a copy. Volume 2 is particularly concerned with human morality and the duty and expectations of mankind. Here the author is keen to show that scientific observation is not necessarily in conflict with religious conviction. (shrink)

The appearance of Priestley's electrical work as a brief and irrelevant prelude to his more substantial chemical enquiries may explain why it has been strangely overlooked by historians of science. It was only fairly recently that Sir Philip Hartog sought to rectify this situation with the affirmation that ‘Priestley's electrical work offers the key to Priestley's scientific mind’. Attacking traditional chemical historiography for tracing Priestley's opposition to Lavoisier's theory to a deficiency in his scientific sensibilities, Hartog insisted that Priestley's natural (...) philosophy can properly be understood only in relation to his ‘profound convictions on scientific method’ as fully expressed in the History of electricity. Only thus would Priestley's scientific thought be related correctly to his ‘work as a whole’. (shrink)

Joseph Priestley, the eighteenth-century scientist who discovered oxygen, was one of the most remarkable thinkers of his time. This collection of essays by a team of experts covers the full range of his work in the fields of education, politics, philosophy, and theology, and firmly re-establishes him as a major intellectual figure.
