Sir Arthur Eddington in his recent book has presented a relatively non-technical account of the theory of the fundamental laws and constants of physics which he developed in his Relativity Theory of Protons and Electrons. But he has also embedded his contributions to science, which are recognised to be of the greatest importance, in a philosophical setting which carries by no means the same authority. It is unfortunate that physical advances, the brilliance of which it would be impertinent to commend, should be obscured, by reason of this embellishment, as seems to have happened in recent controversy. It seems useful, therefore, to discuss what is the real status of Eddington’s results, what points of interest arise from his reflections on the method of physics, and what is true in those parts of the book which deal with genuinely philosophical questions. We shall be mainly concerned with the philosophical setting, and scientific technicalities will be reduced to a minimum.

9 Another example is to be found in Einstein and Infeld's Evolution of Physics (Cambridge, 1938), where the changeover from the mechanical models of nineteenth-century physics to more modern views is regarded as a chmge of philosophical outlook.

12 So also students of symbolic logic can proceed without asking the philosopher to decide what they mean by propositions, the self, etc., in virtue of the device of logical constructions.

15 It is curious that Eddington does not seem to be aware of Whitehead's work, although he writes much about ‘epistemology’; he is astonished to find that the view that science is concerned with the ‘rational correlation of experience, rather than the discovery of fragments of absolute truth about an external world,’ is commonly accepted.
