Gillette shows that the sciences of sociobiology and evolutionary psychology were undergoing rapid development in the early Twentieth century. However, many of the early researchers in these sciences were also eugenicists. With the rise of behaviourism and the reaction against eugenics in the 1930s, any scientific claims that behaviour might be influenced by heredity were suppressed for ideological reasons.

Based on previously unexplored archival documentation, this book offers the first general overview of the history of Italian eugenics, not limited to the decades of Fascist regime, but instead ranging from the beginning of the 1900s to the first half of the 1970s. The Author discusses several fundamental themes of the comparative history of eugenics: the importance of the Latin eugenic model; the relationship between eugenics and fascism; the influence of Catholicism on the eugenic discourse and the complex links between genetics and eugenics. It examines the Liberal pre-fascist period and the post-WW2 transition from fascist and racial eugenics to medical and human genetics. As far as fascist eugenics is concerned, the book provides a refreshing analysis, considering Italian eugenics as the most important case-study in order to define Latin eugenics as an alternative model to its Anglo-American, German and Scandinavian counterparts. Analyses in detail the nature-nurture debate during the State racist campaign in fascist Italy (1938–1943) as a boundary tool in the contraposition between the different institutional, political and ideological currents of fascist racism.

Why the “nature versus nurture” debate persists despite widespread recognition that human traits arise from the interaction of nature and nurture. If everyone now agrees that human traits arise not from nature or nurture but from the interaction of nature and nurture, why does the “nature versus nurture” debate persist? In Beyond Versus, James Tabery argues that the persistence stems from a century-long struggle to understand the interaction of nature and nurture—a struggle to define what the interaction of nature and nurture is, how it should be investigated, and what counts as evidence for it. Tabery examines past episodes in the nature versus nurture debates, offers a contemporary philosophical perspective on them, and considers the future of research on the interaction of nature and nurture. From the eugenics controversy of the 1930s and the race and IQ controversy of the 1970s to the twenty-first-century debate over the causes of depression, Tabery argues, the polarization in these discussions can be attributed to what he calls an “explanatory divide”—a disagreement over how explanation works in science, which in turn has created two very different concepts of interaction. Drawing on recent developments in the philosophy of science, Tabery offers a way to bridge this explanatory divide and these different concepts integratively. Looking to the future, Tabery evaluates the ethical issues that surround genetic testing for genes implicated in interactions of nature and nurture, pointing to what the future does (and does not) hold for a science that continues to make headlines and raise controversy.

Following his highly praised and bestselling book Genome: The Autobiography of a Species in 23 Chapters, Matt Ridley has written a brilliant and profound book about the roots of human behavior. Nature via Nurture explores the complex and endlessly intriguing question of what makes us who we are. In February 2001 it was announced that the human genome contains not 100,000 genes, as originally postulated, but only 30,000. This startling revision led some scientists to conclude that there are simply not enough human genes to account for all the different ways people behave: we must be made by nurture, not nature. Yet again biology was to be stretched on the Procrustean bed of the nature-nurture debate. Matt Ridley argues that the emerging truth is far more interesting than this myth. Nurture depends on genes, too, and genes need nurture. Genes not only predetermine the broad structure of the brain, they also absorb formative experiences, react to social cues, and even run memory. They are consequences as well as causes of the will. Published fifty years after the discovery of the double helix of DNA, Nature via Nurture chronicles a revolution in our understanding of genes. Ridley recounts the hundred years' war between the partisans of nature and nurture to explain how this paradoxical creature, the human being, can be simultaneously free-willed and motivated by instinct and culture. Nature via Nurture is an enthralling,up-to-the-minute account of how genes build brains to absorb experience.

Explores the political forces underlying shifts in thinking about the respective influence of heredity and environment in shaping human behavior, and the feasibility and morality of eugenics.
