Reproduction of the original: Inquiries Into Human Faculty and Its Development by Francis Galton

The word Eugenics first appears in this book. Also, in this book, Galton shows mathematically "the results of his experiments on the relations between the powers of visual imagery and of abstract thought."

Inquiries into Human Faculty and Its Development by Sir Francis Galton: This book is a study of human ability and intelligence, exploring topics such as hereditary and environmental factors in intellectual development, different types of intelligence, and the role of education in shaping intelligence. The book is considered one of the earliest examples of work in the field of psychometrics, which seeks to measure human mental ability through standardized tests. Key Aspects of the Book "Inquiries into Human Faculty and Its Development": Psychometrics: The book is a foundational work on the subject of psychometrics, which seeks to measure human mental ability through standardized tests and other means. Intelligence and Ability: The book explores the factors that contribute to intellectual development and the different types of intelligence that exist in humans. Scientific Method: Galton's work is significant for its application of scientific methods and statistical analysis to the study of human ability and intelligence. Sir Francis Galton was an English scientist and polymath in the nineteenth century. Known for his contributions to a variety of fields, including psychology, genetics, and statistics, Galton is often considered one of the founders of human intelligence testing. In addition to "Inquiries into Human Faculty and Its Development," Galton's other notable works include "Hereditary Genius" and "The Art of Travel."

This edition first published in 1970. Francis Galton has been honoured as the founder of biostatics and one of the creators of modern psychology. His principal aim was to establish a body of statistical knowledge about mental heredity which would result in a new pattern of behaviour for society. The relationship between outstanding men had led him to conclude that mental traits are inherited, and that an ideal society would take advantage of this "fact". In this particular work, which he termed a "Natural History of the English Men of Science of the present day", he examined at great length the antecedents, environment, education and hereditary features of the most prominent men of science in order to establish certain laws relating to heredity. It is a landmark in the transition from introspective to objective methods in biological and psychological research, and the author’s statistical, nonanecdotal approach was to prove immensely fruitful for the development of psychology. Indeed the questionnaire included in the work is probably the earliest in existence. As Professor Cowan points out in her introduction, historians as well as scientists intent upon a deeper understanding of the Victorian mind will find much of interest in this remarkable book.
