Ranging widely across premodern European thought and culture, Leah DeVun reveals how and why efforts to define “the human” so often hinged on ideas about nonbinary sex. The Shape of Sex examines a host of thinkers—theologians, cartographers, natural philosophers, lawyers, poets, surgeons, and alchemists—who used ideas about nonbinary sex as conceptual tools to order their political, cultural, and natural worlds. DeVun reconstructs the cultural landscape navigated by individuals whose sex or gender did not fit the binary alongside debates about animality, sexuality, race, religion, and human nature. The Shape of Sex charts an embrace of nonbinary sex in early Christianity, its brutal erasure at the turn of the thirteenth century, and a new enthusiasm for nonbinary transformations at the dawn of the Renaissance. Along the way, DeVun explores beliefs that Adam and Jesus were nonbinary-sexed; images of “monstrous races” in encyclopedias, maps, and illuminated manuscripts; justifications for violence against purportedly nonbinary outsiders such as Jews and Muslims; and the surgical “correction” of bodies that seemed to flout binary divisions. In a moment when questions about sex, gender, and identity have become incredibly urgent, The Shape of Sex casts new light on a complex and often contradictory past. It shows how premodern thinkers created a system of sex and embodiment that both anticipates and challenges modern beliefs about what it means to be male, female—and human.

Global history records an astonishing variety of forms of social organization. Yet almost universally, males subordinate females. How does the relationship between men and women shape the wider political order? The First Political Order is a groundbreaking demonstration that the persistent and systematic subordination of women underlies all other institutions, with wide-ranging implications for global security and development. Incorporating research findings spanning a variety of social science disciplines and comprehensive empirical data detailing the status of women around the globe, the book shows that female subordination functions almost as a curse upon nations. A society’s choice to subjugate women has significant negative consequences: worse governance, worse conflict, worse stability, worse economic performance, worse food security, worse health, worse demographic problems, worse environmental protection, and worse social progress. Yet despite the pervasive power of social and political structures that subordinate women, history—and the data—reveal possibilities for progress. The First Political Order shows that when steps are taken to reduce the hold of inequitable laws, customs, and practices, outcomes for all improve. It offers a new paradigm for understanding insecurity, instability, autocracy, and violence, explaining what the international community can do now to promote more equitable relations between men and women and, thereby, security and peace. With comprehensive empirical evidence of the wide-ranging harm of subjugating women, it is an important book for security scholars, social scientists, policy makers, historians, and advocates for women worldwide.

Human genomes are 99.9 percent identical—with one prominent exception. Instead of a matching pair of X chromosomes, men carry a single X, coupled with a tiny chromosome called the Y. Tracking the emergence of a new and distinctive way of thinking about sex represented by the unalterable, simple, and visually compelling binary of the X and Y chromosomes, Sex Itself examines the interaction between cultural gender norms and genetic theories of sex from the beginning of the twentieth century to the present, postgenomic age. Using methods from history, philosophy, and gender studies of science, Sarah S. Richardson uncovers how gender has helped to shape the research practices, questions asked, theories and models, and descriptive language used in sex chromosome research. From the earliest theories of chromosomal sex determination, to the mid-century hypothesis of the aggressive XYY supermale, to the debate about Y chromosome degeneration, to the recent claim that male and female genomes are more different than those of humans and chimpanzees, Richardson shows how cultural gender conceptions influence the genetic science of sex. Richardson shows how sexual science of the past continues to resonate, in ways both subtle and explicit, in contemporary research on the genetics of sex and gender. With the completion of the Human Genome Project, genes and chromosomes are moving to the center of the biology of sex. Sex Itself offers a compelling argument for the importance of ongoing critical dialogue on how cultural conceptions of gender operate within the science of sex.

Most modern discussions of the relationship of biological sex to gender presuppose that there are two genders, male and female, founded on the two biological sexes. But not all cultures share this essentialist assumption, and even Western societies have not always embraced it. Bringing together historical and anthropological studies, Third Sex, Third Gender challenges the usual emphasis on sexual dimorphism and reproduction, providing a unique perspective on the various forms of socialization of people who are neither “male” nor “female.” The existence of a third sex or gender enables us to understand how Byzantine palace eunuchs and Indian hijras met the criteria of special social roles that necessitated practices such as self-castration, and how intimate and forbidden desires were expressed among the Dutch Sodomites in the early modern period, the Sapphists of eighteenth-century England, or the so-called hermaphrodite-homosexuals of nineteenth-century Europe and America. By contextualizing these practices and by allowing these bodies, meanings, and desires to emerge, Third Sex, Third Gender provides a new way to think about sex and gender systems that is crucial to contemporary debates within the social sciences.

Sex and World Peace is a groundbreaking demonstration that the security of women is a vital factor in the occurrence of conflict and war, unsettling a wide range of assumptions in political and security discourse. Harnessing an immense amount of data, it relates microlevel violence against women and macrolevel state peacefulness across global settings. The authors find that the treatment of women informs human interaction at all levels of society. They call attention to the adverse effects on state security of sex-based inequities such as sex ratios favoring males, the practice of polygamy, and lax enforcement of national laws protecting women. Their research challenges conventional definitions of security and democracy and common understandings of the causes of world events. The book considers a range of ways to remedy these injustices, including top-down and bottom-up approaches to redressing violence against women and the lack of sex parity in decision-making. Advocating a state responsibility to protect women, the authors campaign against women’s systemic insecurity, which threatens the security of all. Sex and World Peace has been a go-to book for instructors, advocates, and policy makers since its publication in 2012. Since then, there have been major changes in world affairs, including the #MeToo movement, as well as advances in both theoretical and empirical literature surrounding the subject. This second edition, which adds coauthors Rose McDermott and Donna Lee Bowen alongside Valerie M. Hudson and Mary Caprioli, revises and updates the book for a new generation. The book retains its foundational overview of the relationship between women’s oppression and war, enhanced by fresh data and new material covering recent developments for global women’s rights and analysis of additional examples of gender and conflict throughout the world.

A reexamination of the origins of modern science; discovers a forgotten heritage of women scientists and probes the cultural and historical forces that continue to shape the course of scientific scholarship and knowledge.

How Sex Changed is a fascinating social, cultural, and medical history of transsexuality in the United States. Joanne Meyerowitz tells a powerful human story about people who had a deep and unshakable desire to transform their bodily sex. In the last century when many challenged the social categories and hierarchies of race, class, and gender, transsexuals questioned biological sex itself, the category that seemed most fundamental and fixed of all. From early twentieth-century sex experiments in Europe, to the saga of Christine Jorgensen, whose sex-change surgery made headlines in 1952, to today’s growing transgender movement, Meyerowitz gives us the first serious history of transsexuality. She focuses on the stories of transsexual men and women themselves, as well as a large supporting cast of doctors, scientists, journalists, lawyers, judges, feminists, and gay liberationists, as they debated the big questions of medical ethics, nature versus nurture, self and society, and the scope of human rights. In this story of transsexuality, Meyerowitz shows how new definitions of sex circulated in popular culture, science, medicine, and the law, and she elucidates the tidal shifts in our social, moral, and medical beliefs over the twentieth century, away from sex as an evident biological certainty and toward an understanding of sex as something malleable and complex. How Sex Changed is an intimate history that illuminates the very changes that shape our understanding of sex, gender, and sexuality today.

A provocative description of the power of population change to create the conditions for societal transformation. As the world nears 8 billion people, the countries that have led the global order since World War II are becoming the most aged societies in human history. At the same time, the world’s poorest and least powerful countries are suffocating under an imbalance of population and resources. In 8 Billion and Counting, political demographer Jennifer D. Sciubba argues that the story of the twenty-first century is less a story about exponential population growth, as the previous century was, than it is a story about differential growth—marked by a stark divide between the world’s richest and poorest countries. Drawing from decades of research, policy experience, and teaching, Sciubba employs stories and statistics to explain how demographic trends, like age structure and ethnic composition, are crucial signposts for future violence and peace, repression and democracy, poverty and prosperity. Although we have a diverse global population, demographic trends often follow predictable patterns that can help professionals across the corporate, nonprofit, government, and military sectors understand the global strategic environment. Through the lenses of national security, global health, and economics, Sciubba demonstrates the pitfalls of taking population numbers at face value and extrapolating from there. Instead, she argues, we must look at the forces in a society that amplify demographic trends and the forces that dilute them, particularly political institutions, or the rules of the game. She shows that the most important skills in demographic analysis are naming and being aware of your preferences, rethinking assumptions, and asking the right questions. Provocative and engrossing, 8 Billion and Counting is required reading for business leaders, policy makers, and anyone eager to anticipate political, economic, and social risks and opportunities. A deeper understanding of fertility, mortality, and migration promises to point toward the investments we need to make today to shape the future we want tomorrow.
