Applied Eugenics   By: Roswell H. (Roswell Hill) Johnson (1877-1967)

In Applied Eugenics, Roswell H. Johnson presents a comprehensive study on a controversial subject: eugenics. Written over a century ago, this book offers an insightful perspective into the history of eugenics and its potential implications for the future of humanity.

Johnson opens the book with a thoughtful exploration of the fundamental principles of eugenics. He defines eugenics as the science of improving the human race through selective breeding, aiming to eliminate undesirable traits and enhance desirable ones. Drawing upon an array of scientific knowledge, Johnson presents various arguments and examples to support the idea that eugenics can lead to the betterment of society.

One noteworthy aspect of Applied Eugenics is Johnson's examination of the practical applications of eugenics. He explores topics such as genetic counseling, marriage selection, and sterilization, bringing up case studies and real-life examples to illustrate the potential benefits of eugenic practices. Although some of these examples may raise ethical concerns from a modern standpoint, they shed light on the prevailing perspectives of the time.

Johnson’s extensive research is evident throughout the book. He delves into the history of eugenics, discussing its roots in ancient civilizations and tracing its development to the modern era. By drawing on various sources and blending them with his own analysis, Johnson provides readers with a comprehensive understanding of the subject. However, the book's dated nature means that some of the scientific knowledge presented requires a critical lens, as it may no longer align with contemporary advancements in genetics.

While it is essential to acknowledge the historical context in which Applied Eugenics was written, it is equally important to grapple with the book's implications. The scientific community has since widely rejected many eugenic ideas, highlighting their discriminatory nature and the potential for abuse. Yet, Johnson's work remains a valuable resource for understanding the emergence and early reception of eugenics as a scientific field.

In conclusion, Applied Eugenics by Roswell H. Johnson is an influential book that examines the theory and practice of eugenics during a pivotal era in its development. Despite its age, the book provides valuable insight into the history and ideologies surrounding the eugenics movement. Nevertheless, readers must approach this text critically, taking into account the ethical considerations and advancements made in genetic research since its publication.

The science of eugenics consists of a foundation of biology and a superstructure of sociology. Galton, its founder, emphasized both parts in due proportion. Until recently, however, most sociologists have been either indifferent or hostile to eugenics, and the science has been left for the most part in the hands of biologists, who have naturally worked most on the foundations and neglected the superstructure. Although we are not disposed to minimize the importance of the biological part, we think it desirable that the means of applying the biological principles should be more carefully studied. The reader of this book will, consequently, find only a summary explanation of the mechanism of inheritance. Emphasis has rather been laid on the practical means by which society may encourage the reproduction of superior persons and discourage that of inferiors... Continue reading book >>
