Today physicians rely on sophisticated scientific knowledge, and no longer offer the traditional doctor-patient relationship which ministered to psychological as well as physical comfort. But it is this spiritual aspect of human medicine, Dr. Dubos argues, which distinguishes it from general biology, and it will retain its unique position among the sciences only if it accepts responsibility for the human aspects of life. Dr. Dubos demonstrates the complex interrelationship between man and his biological environment. He writes, "I have attempted to focus my attention on the individual human being . . . trying as best he can to meet the emergencies of the day and to prepare for the uncertainties of the future. He is Man Adapting."
