The book discusses the relationship between science and other disciplines, emphasizing that science is more generous than some scientists claim and connects with art and poetry. Dr. Hesse explores the status of scientific theory, favoring an operational view where science answers "what will happen if I do that," dismissing explanations as unnecessary. She criticizes Eddington and Dirac for concepts not definable by direct measurement. However, she acknowledges that scientific work involves awareness of real things. The second half of the book is weaker, with Hesse uncertain. She concludes that a synthesis of science and religion is not possible until the Kingdom of God, and that transcendental faith remains unanswered. The author believes science is a silent witness to transcendental faith, as it deals with a reality that commands study. The book is readable and stimulating, though the author suggests more biology and questions about scientists could have strengthened it. The book also reviews "Receptors and Sensory Perception" by Dr. Ragnar Granit, discussing electrophysiological research on sensory processes. It highlights Granit's contributions to vision physiology and his work on the retina. The book is a valuable addition to the Silliman Lectures series. Another review discusses "International Coordination of Galactic Research," edited by A. Blaauw. It notes advances in stellar system research, particularly in radio astronomy, which has provided new insights into interstellar matter. Despite some interpretations remaining unclear, radio astronomy continues to yield important results.The book discusses the relationship between science and other disciplines, emphasizing that science is more generous than some scientists claim and connects with art and poetry.
