Lynn (psychology, U. of Ulster) defends human breeding and culling based on eight propositions, among them that certain human qualities are valuable because they provide the foundation for a nation's intellectual and cultural achievement, that such qualities are to a substantial extent genetically determined and so can be genetically improved, and that human biotechnology can be used to achieve eugenic objectives. He begins with the history of the belief, then sets out its objects and the implementation of its classical form, and describes the new eugenics. He mentions Nazi Germany briefly twice to defend its eugenics practices.
