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.
