This book originated in the belief that there is an urgent need at the present time for a greater association between philosophers and scientists and of both with religious people. The problem of bringing this association into being is approached from different angles by the two authors, who, while agreeing on the main thesis, differ on many details, and the discussion is largely concerned with an examination of the points of difference. It ranges over the significance of scientific concepts, such as ether, energy, space and time, the place of mathematics in science and of linguistics in philosophy, the nature of scientific thought in relation to the universe as a whole, problems of life, mind, ethics and theology. It also raises questions of importance concerning the present attitudes of organizations dealing with these matters towards their respective concerns.
In the course of the discussion, Dingle described how a scientific paper critical of special relativity was rejected by various journals. Part of the paper is reproduced as Appendix II of the book, and is a very clear description of his "Proof that Einstein?s Special Theory cannot correspond with fact."
