"The moral and intellectual wealth of a nation largely consists in the multifarious variety of the gifts of the men who compose it . . ." -Sir Francis Galton, Inquiries into Human Faculty and Its Development Inquiries into Human Faculty and Its Development (1907) by Francis Galton is a landmark work in the field of anthropology. In it, Galton coined the term "eugenics," arguing for a selection system of euthanasia based on a classification of humans. To that end, this book discusses the many differences among humans that can be identified, including physical features, emotions, psychology, character, criminality, gregarious and slavish natures, intellectual differences, mental imagery, the history of twins, and race, among others. This is the 1907 edition updated by the author of the original classic first published in 1883.
