The lectures in this volume were designed for the public. There are seven lectures in this series. They offer a realistic appraisal of the relation of present day medicine to the larger society in which we all live. The moral standards of the community require that the ill be cared for regardless of ability to pay. Medicine is emerging as a social science as well as a natural science. The form of medical practice must not be allowed to interfere with the quality of medical care received. More particularly, compensations and incentives must not be allowed to become other than spurs to better work. The series as a whole comprises a healthy introspective glance into the medical profession.
