“What a strange invention marriage is!” wrote Kierkegaard. “Is it the expression of that inexplicable erotic sentiment, that concordant elective affinity of souls, or is it a duty or a partnership . . . or is it a little of all that?”

Like Kierkegaard a few decades later, many of Germany’s most influential thinkers at the turn of the eighteenth century wondered about the nature of marriage but rejected the easy answers provided by biology and theology. In Uncivil Unions, Adrian Daub presents a truly interdisciplinary look at the story of a generation of philosophers, poets, and intellectuals who turned away from theology, reason, common sense, and empirical observation to provide a purely metaphysical justification of marriage.

Through close readings of philosophers like Fichte and Schlegel, and novelists like Sophie Mereau and Jean Paul, Daub charts the development of this new concept of marriage with an insightful blend of philosophy, cultural studies, and theory. The author delves deeply into the lives and work of the romantic and idealist poets and thinkers whose beliefs about marriage continue to shape ideas about gender, marriage, and sex to the present day.

On December 5, 2004, the still-developing blogosphere took one of its biggest steps toward mainstream credibility, as Nobel Prize–winning economist Gary S. Becker and renowned jurist and legal scholar Richard A. Posner announced the formation of the Becker-Posner Blog.

In no time, the blog had established a wide readership and reputation as a reliable source of lively, thought-provoking commentary on current events, its pithy and profound weekly essays highlighting the value of economic reasoning when applied to unexpected topics. Uncommon Sense gathers the most important and innovative entries from the blog, arranged by topic, along with updates and even reconsiderations when subsequent events have shed new light on a question. Whether it’s Posner making the economic case for the legalization of gay marriage, Becker arguing in favor of the sale of human organs for transplant, or even the pair of scholars vigorously disagreeing about the utility of collective punishment, the writing is always clear, the interplay energetic, and the resulting discussion deeply informed and intellectually substantial.

To have a single thinker of the stature of a Becker or Posner addressing questions of this nature would make for fascinating reading; to have both, writing and responding to each other, is an exceptionally rare treat. With Uncommon Sense, they invite the adventurous reader to join them on a whirlwind intellectual journey. All they ask is that you leave your preconceptions behind.

The Catholic Church of early modern Europe intended the sacrament of matrimony to represent a lifelong commitment, and it allowed few grounds for the dissolution of an unhappy marriage. One was nonconsummation owing to the sexual impotency of one of the partners. Even then, an annulment was granted only after a church court had conducted a lengthy investigation of the case, soliciting testimony from numerous witnesses as well as from the aggrieved couple, and had subjected the allegedly impotent spouse (and sometimes both spouses) to an intimate physical examination.

Edward J. Behrend-Martinez has studied the transcripts of eighty-three impotency trials conducted by the ecclesiastical court of Calahorra (La Rioja), a Spanish diocese with urban and rural parishes, both Basque and Castilian. From these records, he draws a detailed, fascinating portrait of private life and public sexuality in early modern Europe. These trials were far more than a salacious inquiry into the intimate details of other people’s lives. The church valued marital sex as a cornerstone of stable society, intended not only for procreation but also for maintaining domestic harmony. Every couple’s sex life, however private in practice or intention, was a matter of public and ecclesiastical concern.

Unfit for Marriage offers vivid accounts of marital sex and the role that property, gender, and personal preference played in marriage in early modern Europe. It is essential reading for anyone interested in social history, sexuality, gender studies, canon law, legal history, and the history of divorce in western Europe.

For centuries, people have been thinking and writing—and fiercely debating—about the meaning of marriage. Just a hundred years ago, Progressive era reformers embraced marriage not as a time-honored repository for conservative values, but as a tool for social change.

In Until Choice Do Us Part, Clare Virginia Eby offers a new account of marriage as it appeared in fiction, journalism, legal decisions, scholarly work, and private correspondence at the turn into the twentieth century. She begins with reformers like sexologist Havelock Ellis, anthropologist Elsie Clews Parsons, and feminist Charlotte Perkins Gilman, who argued that spouses should be “class equals” joined by private affection, not public sanction.  Then Eby guides us through the stories of three literary couples—Upton and Meta Fuller Sinclair, Theodore and Sara White Dreiser, and Neith Boyce and Hutchins Hapgood—who sought to reform marriage in their lives and in their writings, with mixed results. With this focus on the intimate side of married life, Eby views a historical moment that changed the nature of American marriage—and that continues to shape marital norms today.
