Not a book for the reader who wants a tabloid approach to a rationalization of modern science in terms of a working philosophy. This is distinctly keyed to the reader with considerable technical and philosophical background, and for such readers (i.e. your James, Eddington, Whitehead enthusiasts, for instance), there is food for thought, and a certain challenge in the handling of moot problems. The author develops a constructive case for humanism as ""the only gospel of social reform consistent with the method and the results of modern science.
