In these days Science like everything else has to justify itself. Even the search for truth, as that for power, which used to be the two alternative views of Science, assert with difficulty its absolute value. The author, imbued with the modern relativist attitude, enquires searchingly into the various functions of science, philosophical, social and so on. In this task he is much hampered by a lack of familiarity with modern psychology and asserts, in a way rather characteristic of physicists, that 'psychology is still very much of a pseudo-science'.

His real interest would seem to be in practice rather than in theory, and above all in the organization of research work. In this field he presents a mass of invaluable data, especially those concerning the relation between industry and scientific research. He has no difficulty in showing how research work could be better organized and be of greater value to the community.
