The Fertility of the Unfit

by W. A. (William Allan) Chapple

"The Fertility of the Unfit" by W. A. Chapple is a scientific publication written in the early 20th century. The book addresses pressing questions related to population dynamics, particularly the concerning rise in the birth rate among the "unfit" segments of society, such as criminals and defectives, while the "fit" exhibit a declining birth rate. Chapple’s examination highlights issues of moral restraint, societal responsibility, and the long-term implications of these demographic trends on civilization. At the start of the work, the author discusses the gravity of the problem of increasing numbers of unfit individuals contributing to society and the alarming implications for future generations. The preface by Rutherford Waddell emphasizes the need for a serious discussion on the topic, with solutions ranging from indeterminate sentences for criminals to the proposal of limiting the fertility of the unfit through various methods. The opening chapters set the stage for a detailed analysis of the factors contributing to the declining birth rates among the fit population and the rising birth rates among the unfit, touching upon historical perspectives, biological laws, and societal attitudes towards family planning.
