The idea that we can establish foundational principles of physical theories on pure reason alone did not die with Newtons rejection of Cartesian rationalism. Darrigol, the author of a number of valuable works on the history of physics, explores latter day rationalisms, focusing on those that follow Helmholtz in seeking for necessary conditions on the interpretation and application of theories. Darrigol offers his own account on how theories must be interpreted and applied and how the necessity for these may very well be taken as establishing a limited kind of rational support for some principles of foundational physics.

In this excellently written book, Darrigol steps back to survey the history of necessity in physics, and the richness of the necessitarian programme despite that programme's (sometimes embarrassing) trail of failures. What he shows is the persistence of the belief in a rational and comprehensible universe and the importance of that belief for the development of empirical science --- whatever sober, empirical reservations come in to philosophical fashion. Reading this book may remind us all why we were interested in philosophy in the first place.
