Inquiries into Human Faculty and Its Development

By Francis Galton. Sir Francis Galton invented the term eugenics and set down many of his observations and conclusions in this book which covers a variety of psychological phenomena and their subsequent measurement.

It discusses the variety of human nature, physical features, bodily qualities, emotions, psychology, anthropometric registers, character, criminals, gregarious and slavish instincts, intellectual differences, mental imagery, number forms, the history of twins, and selection and race, among others.

He also advocated a system of rewards for high quality families to have more children to encourage the better element of society to grow in size.
