This open access book provides the first explicit case study for an application of the method
of reflective equilibrium (RE) using it to develop and defend a precautionary principle. It
thereby makes an important and original contribution to questions of philosophical method and
methodology. The book shows step-by-step how RE is applied and develops a methodological
framework which will be useful for everyone who wishes to use reflective equilibrium. With
respect to precautionary principles the book demonstrates how a rights-based precautionary
principle can be constructed and defended. The case study succeeds in demonstrating that RE can
be successfully applied and puts real constraints on the justification process. This is all the
more remarkable as the case study was designed as an open-ended process without presupposing
any specific results. This book will be highly relevant both to people interested in
philosophical methodology and epistemology as well as to researchers who are interested in
using philosophical methods and tools and applying them to practical problems.
