This book presents a thoroughly empiricist account of physics. By providing an overview of the development of empiricism from Ockham to van Fraassen the book lays the foundation for its own version of empiricism. Empiricism for the author consists of three ideas: nominalism, i.e. dismissing second order quantification as unnecessary, epistemological naturalism, and viewing classification of things in natural kinds as a human habit not in need for any justification.
The book offers views on the realism-antirealism debate as well as on the individuation of theories as a thoroughly neglected aspect of underdetermination. The book next discusses a broad range of topics, including the predicates body, spatial distance and time interval, the ontology of electromagnetism, propensities, the measurement problem and other philosophical issues in quantum theory. Discussions about the direction of time and about string theory make up the final part of the book.
Autorentext
After receiving a Ph.D in theoretical philosophy from Stockholm University 1993 I was lecturer in theoretical philosophy at Linköping University 1995-2001, after which I moved to Uppsala University, where I became full professor 2008. My research interests are epistemology, philosophy of science and in particular philosophy of physics. I have extensively taught philosophy of science also at Karolinska Institute, Stockholm, Royal University of Technology in Stockholm and Swedish University for Agricultural Sciences in Uppsala.
