Sergio Sismondo's “Boundary Work and the Science Wars” nicely exemplifies a hotly debated central issue. One side, let me call them the rationalists, tries to explain episodes in the history of science in terms of reason. They claim that scientists, past and present, believe what they do because of the evidence that they have at the time. The other side, following Sismondo, let me call them STSers , claim that social and other non-cognitive factors are the frequent causes of belief. This disagreement naturally leads to a meta-level debate. Rationalists, such as myself, try to give reasons for believing the STSers are wrong-headed in their approach. And Sismondo replies with the claim that whether I realize it or not I am really doing boundary work – an explanation of my activity in terms of social factors

There is sufficient evidence that intellectual property rights are corrupting medical research. One could respond to this from a moral or from an epistemic point of view. I take the latter route. Often in the sciences factual discoveries lead to new methodological norms. Medical research is an example. Surprisingly, the methodological change required will involve political change. Instead of new regulations aimed at controlling the problem, the outright socialization of research seems called for, for the sake of better science. I appeal to an analogy between socialized medicine and socialized research. †To contact the author, please write to: Department of Philosophy, University of Toronto, Toronto, Ontario M5R 2M8, Canada; e‐mail: [email protected].

Everyone appreciates a clever mathematical picture, but the prevailing attitude is one of scepticism: diagrams, illustrations, and pictures prove nothing; they are psychologically important and heuristically useful, but only a traditional verbal/symbolic proof provides genuine evidence for a purported theorem. Like some other recent writers (Barwise and Etchemendy [1991]; Shin [1994]; and Giaquinto [1994]) I take a different view and argue, from historical considerations and some striking examples, for a positive evidential role for pictures in mathematics.

From the 19th century the philosophy of science has been shaped by a group of influential figures. Who were they? Why do they matter? This introduction brings to life the most influential thinkers in the philosophy of science, uncovering how the field has developed over the last 200 years. Taking up the subject from the time when some philosophers began to think of themselves not just as philosophers but as philosophers of science, a team of leading contemporary philosophers explain, criticize and honour the giants. Now updated and revised throughout, the second edition includes: - Easy-to-follow overviews of pivotal thinkers including John Stuart Mill, Rodolf Carnap, Thomas Kuhn and Karl Popper - Coverage of central issues such as experience and necessity, logical empiricism, the sociology of science and realism - An afterword looking ahead to emerging research trends - Study questions and further reading lists at the end of each chapter Philosophy of Science: The Key Thinkers demonstrates how the ideas and arguments of this group of key thinkers laid the foundations of our understanding of modern science.

According to the standard view of definition, all defined terms are mere stipulations, based on a small set of primitive terms. After a brief review of the Hilbert-Frege debate, this paper goes on to challenge the standard view in a number of ways. Examples from graph theory, for example, suggest that some key definitions stem from the way graphs are presented diagramatically and do not fit the standard view. Lakatos's account is also discussed, since he provides further examples that suggest many definitions are much more than mere convenient abbreviations.

Newton's bucket, Einstein's elevator, Schrödinger's cat – these are some of the best-known examples of thought experiments in the natural sciences. But what function do these experiments perform? Are they really experiments at all? Can they help us gain a greater understanding of the natural world? How is it possible that we can learn new things just by thinking? In this revised and updated new edition of his classic text _The Laboratory of the Mind_, James Robert Brown continues to defend apriorism in the physical world. This edition features two new chapters, one on “counter thought experiments” and another on the development of inertial motion. With plenty of illustrations and updated coverage of the debate between Platonic rationalism and classic empiricism, this is a lively and engaging contribution to the field of philosophy of science
