SLIDE 16 "At the frontiers of physics and cosmology theoretical speculation proceeds without the constant confrontation with experiment

ften thought to be required for scientific
validation. Richard Dawid explores this

issue in the case of string theory. He offers a fascinating new perspective on non- empirical theory assessment, DG "Richard Dawid argues that string theory plays a novel role in the scientific process that has been neglected by philosophers of science. I believe that this book is a valuable contribution to the philosophy of science, which should interest practicing scientists as well as those who are more interested in the methodology of science." John Schwarz
