In the second half of the book, Dr. Hesse discusses the status of scientific theory, favoring the operational view that science should provide answers to practical questions without unnecessary explanations or interpretations. She criticizes Eddington and Dirac for their concepts that are not directly measurable, but acknowledges the intuitive element in scientific work. However, she remains uncertain about a synthesis of science and religion, suggesting that it is beyond human reach. The reviewer suggests that incorporating more biology and questions about the scientist's role could strengthen the argument. Despite some inaccuracies, the book's honesty and recognition of the roles of science, art, and religion are commendable. The review also mentions Ragnar Granit's book "Receptors and Sensory Perception," which is an up-to-date presentation of neurophysiology for a broad scientific audience. Granit's contributions to vision physiology are well-received, and the book provides a clear defense of his dominator-modulator theory for color vision. The concluding chapters on muscle receptors are particularly interesting for their detailed exploration of how nervous mechanisms adjust receptors to provide accurate information. Finally, the review touches on the edited volume "International Co-ordination of Galactic Research," which highlights the rapid advancements in radio astronomy and the growing interest in galactic research. While many radio observations lack clear interpretation, the tools are now available to map the spirals of the Milky Way.In the second half of the book, Dr. Hesse discusses the status of scientific theory, favoring the operational view that science should provide answers to practical questions without unnecessary explanations or interpretations.
