First published in 1941, Sex and Citizenship encourages people to think constructively about our moral problems. The author argues that sexual relationships have in the past been largely based upon self-interest. We have yet to try a moral code based upon trust, equality, and love, backed by knowledge and reason. The book discusses themes such as moral problem; religion and science; friendship; principles of sex relationships; marriage, parents and children; marriage preparation; and the future. The philosophy and theology of this book are those of a practicing doctor who is in daily contact with these problems. This book is not intended as a theological treatise and is an important historical reference for scholars of sociology.
