In a book that moves between philosophy and history, and with lasting significance for both, Arnold Davidson elaborates a powerful new method for considering the history of concepts and the nature of scientific knowledge, a method he calls "historical epistemology." He applies this method to the history of sexuality, with important consequences for our understanding of desire, abnormality, and sexuality itself.

In Davidson's view, it was the emergence of a science of sexuality that made it possible, even inevitable, for us to become preoccupied with our true sexuality. Historical epistemology attempts to reveal how this new form of experience that we call "sexuality" is linked to the emergence of new structures of knowledge, and especially to a new style of reasoning and the concepts employed within it. Thus Davidson shows how, starting in the second half of the nineteenth century, a new psychiatric style of reasoning about diseases emerges that makes possible, among other things, statements about sexual perversion that quickly become commonplace in discussions of sexuality.

Considering a wide range of examples, from Thomas Aquinas to Freud, Davidson develops the methodological lessons of Georges Canguilhem and Michel Foucault in order to analyze the history of our experience of normativity and its deviations.

Few things come more naturally to us than sex—or so it would seem. Yet to a chimpanzee, the sexual practices and customs we take for granted would appear odd indeed. He or she might wonder why we bother with inconveniences like clothes, why we prefer to make love on a bed, and why we fuss so needlessly over privacy. Evolution and Human Sexual Behavior invites us into the thought-experiment of imagining human sex from the vantage point of our primate cousins, in order to underscore the role of evolution in shaping all that happens, biologically and behaviorally, when romantic passions are aroused.

Peter Gray and Justin Garcia provide an interdisciplinary synthesis that draws on the latest discoveries in evolutionary theory, genetics, neuroscience, comparative primate research, and cross-cultural sexuality studies. They are our guides through an exploration of the patterns and variations that exist in human sexuality, in chapters covering topics ranging from the evolution of sex differences and reproductive physiology to the origins of sexual play, monogamous unions, and the facts and fictions surrounding orgasm.

Intended for generally curious readers of all stripes, this up-to-date, one-volume survey of the evolutionary science of human sexual behavior explains why sexuality has remained a core fascination of human beings throughout time and across cultures.

Punctuated with remarkable case studies, this book explores extraordinary encounters between hermaphrodites--people born with "ambiguous" sexual anatomy--and the medical and scientific professionals who grappled with them. Alice Dreger focuses on events in France and Britain in the late nineteenth century, a moment of great tension for questions of sex roles. While feminists, homosexuals, and anthropological explorers openly questioned the natures and purposes of the two sexes, anatomical hermaphrodites suggested a deeper question: just how many human sexes are there? Ultimately hermaphrodites led doctors and scientists to another surprisingly difficult question: what is sex, really?

Hermaphrodites and the Medical Invention of Sex takes us inside the doctors' chambers to see how and why medical and scientific men constructed sex, gender, and sexuality as they did, and especially how the material conformation of hermaphroditic bodies--when combined with social exigencies--forced peculiar constructions. Throughout the book Dreger indicates how this history can help us to understand present-day conceptualizations of sex, gender, and sexuality. This leads to an epilogue, where the author discusses and questions the protocols employed today in the treatment of intersexuals (people born hermaphroditic). Given the history she has recounted, should these protocols be reconsidered and revised?

A meticulously researched account of a fascinating problem in the history of medicine, this book will compel the attention of historians, physicians, medical ethicists, intersexuals themselves, and anyone interested in the meanings and foundations of sexual identity.

This is a book about the making and unmaking of sex over the centuries. It tells the astonishing story of sex in the West from the ancients to the moderns in a precise account of developments in reproductive anatomy and physiology. We cannot fail to recognize the players in Thomas Laqueur’s story—the human sexual organs and pleasures, food, blood, semen, egg, sperm—but we will be amazed at the plots into which they have been woven by scientists, political activists, literary figures, and theorists of every stripe.

Laqueur begins with the question of why, in the late eighteenth century, woman’s orgasm came to be regarded as irrelevant to conception, and he then proceeds to retrace the dramatic changes in Western views of sexual characteristics over two millennia. Along the way, two “master plots” emerge. In the one-sex story, woman is an imperfect version of man, and her anatomy and physiology are construed accordingly: the vagina is seen as an interior penis, the womb as a scrotum, the ovaries as testicles. The body is thus a representation, not the foundation, of social gender. The second plot tends to dominate post-Enlightenment thinking while the one-sex model is firmly rooted in classical learning. The two-sex story says that the body determines gender differences, that woman is the opposite of man with incommensurably different organs, functions, and feelings. The two plots overlap; neither ever holds a monopoly. Science may establish many new facts, but even so, Laqueur argues, science was only providing a new way of speaking, a rhetoric and not a key to female liberation or to social progress. Making Sex ends with Freud, who denied the neurological evidence to insist that, as a girl becomes a woman, the locus of her sexual pleasure shifts from the clitoris to the vagina; she becomes what culture demands despite, not because of, the body. Turning Freud’s famous dictum around, Laqueur posits that destiny is anatomy. Sex, in other words, is an artifice.

This is a powerful story, written with verve and a keen sense of telling detail (be it technically rigorous or scabrously fanciful). Making Sex will stimulate thought, whether argument or surprised agreement, in a wide range of readers.

Most of us assume that sexuality is fixed: either you’re straight, gay, or bisexual. Yet an increasing number of young men today say that those categories are too rigid. They are, they insist, “mostly straight.” They’re straight, but they feel a slight but enduring romantic or sexual desire for men. To the uninitiated, this may not make sense. How can a man be “mostly” straight? Ritch Savin-Williams introduces us to this new world by bringing us the stories of young men who consider themselves to be mostly straight or sexually fluid. By hearing about their lives, we discover a radically new way of understanding sexual and romantic development that upends what we thought we knew about men.

Today there are more mostly straight young men than there are gay and bisexual young men combined. Based on cutting-edge research, Savin-Williams explores the personal stories of forty young men to help us understand the biological and psychological factors that led them to become mostly straight and the cultural forces that are loosening the sexual bind that many boys and young men experience. These young men tell us how their lives have been influenced by their “drop of gayness,” from their earliest sexual memories and crushes to their sexual behavior as teenagers and their relationships as young adults. Mostly Straight shows us how these young men are forging a new personal identity that confounds both traditional ideas and conventional scientific opinion.

An award-winning biologist and writer applies queer feminist theory to developmental genetics, arguing that individuals are not essentially male or female.  
 
The idea that gender is a performance—a tenet of queer feminist theory since the nineties—has spread from college classrooms to popular culture. This transformative concept has sparked reappraisals of social expectations as well as debate over not just gender, but sex: what it is, what it means, and how we know it. Most scientific and biomedical research over the past seventy years has assumed and reinforced a binary concept of biological sex, though some scientists point out that male and female are just two outcomes in a world rich in sexual diversity.   
 
In Performance All the Way Down, MacArthur Fellow and Pulitzer Prize finalist Richard O. Prum brings feminist thought into conversation with biology, arguing that the sexual binary is not essential to human genes, chromosomes, or embryos. Our genomes are not blueprints, algorithms, or recipes for the physical representation of our individual sexual essences or fates. In accessible language, Prum shows that when we look closely at the science, we see that gene expression is a material action in the world, a performance through which the individual regulates and achieves its own becoming. A fertilized zygote matures into an organism with tissues and organs, neurological control, immune defenses, psychological mechanisms, and gender and sexual behavior through a performative continuum. This complex hierarchy of self-enactment reflects the evolved agency of individual genes, molecules, cells, and tissues.
 
Rejecting the notion of an intractable divide between the humanities and the sciences, Prum proves that the contributions of queer and feminist theorists can help scientists understand the human body in new ways, yielding key insights into genetics, developmental biology, physiology. Sure to inspire discussion, Performance All the Way Down is a book about biology for feminists, a book about feminist theory for biologists, and a book for anyone curious about how our sexual bodies grow.
