Americans today “know” that a majority of the population supports the death penalty, that half of all marriages end in divorce, and that four out of five prefer a particular brand of toothpaste. Through statistics like these, we feel that we understand our fellow citizens. But remarkably, such data—now woven into our social fabric—became common currency only in the last century. Sarah Igo tells the story, for the first time, of how opinion polls, man-in-the-street interviews, sex surveys, community studies, and consumer research transformed the United States public.

Igo argues that modern surveys, from the Middletown studies to the Gallup Poll and the Kinsey Reports, projected new visions of the nation: authoritative accounts of majorities and minorities, the mainstream and the marginal. They also infiltrated the lives of those who opened their doors to pollsters, or measured their habits and beliefs against statistics culled from strangers. Survey data underwrote categories as abstract as “the average American” and as intimate as the sexual self.

With a bold and sophisticated analysis, Igo demonstrates the power of scientific surveys to shape Americans’ sense of themselves as individuals, members of communities, and citizens of a nation. Tracing how ordinary people argued about and adapted to a public awash in aggregate data, she reveals how survey techniques and findings became the vocabulary of mass society—and essential to understanding who we, as modern Americans, think we are.

The right of same-sex couples to marry provoked decades of intense conflict before it was upheld by the U.S. Supreme Court in 2015. Yet some of the most divisive contests shaping the quest for marriage equality occurred not on the culture-war front lines but within the ranks of LGBTQ advocates. Nathaniel Frank tells the dramatic story of how an idea that once seemed unfathomable—and for many gays and lesbians undesirable—became a legal and moral right in just half a century.

Awakening begins in the 1950s, when millions of gays and lesbians were afraid to come out, let alone fight for equality. Across the social upheavals of the next two decades, a gay rights movement emerged with the rising awareness of the equal dignity of same-sex love. A cadre of LGBTQ lawyers soon began to focus on legal recognition for same-sex couples, if not yet on marriage itself. It was only after being pushed by a small set of committed lawyers and grassroots activists that established movement groups created a successful strategy to win marriage in the courts.

Marriage equality proponents then had to win over members of their own LGBTQ community who declined to make marriage a priority, while seeking to rein in others who charged ahead heedless of their carefully laid plans. All the while, they had to fight against virulent antigay opponents and capture the American center by spreading the simple message that love is love, ultimately propelling the LGBTQ community—and America—immeasurably closer to justice.

Challenging the formidable tradition that places early New England Puritanism at the center of the American religious experience, Yale historian Jon Butler offers a new interpretation of three hundred years of religious and cultural development. Butler stresses the instability of religion in Europe where state churches battled dissenters, magic, and astonishingly low church participation. He charts the transfer of these difficulties to America, including the failure of Puritan religious models, and describes the surprising advance of religious commitment there between 1700 and 1865. Through the assertion of authority and coercion, a remarkable sacralization of the prerevolutionary countryside, advancing religious pluralism, the folklorization of magic, and an eclectic, syncretistic emphasis on supernatural interventionism, including miracles, America emerged after 1800 as an extraordinary spiritual hothouse that far eclipsed the Puritan achievement—even as secularism triumphed in Europe.

Awash in a Sea of Faith ranges from popular piety to magic, from anxious revolutionary war chaplains to the cool rationalism of James Madison, from divining rods and seer stones to Anglican and Unitarian elites, and from Virginia Anglican occultists and Presbyterians raised from the dead to Jonathan Edwards, Joseph Smith, and Abraham Lincoln. Butler deftly comes to terms with conventional themes such as Puritanism, witchcraft, religion and revolution, revivalism, millenarianism, and Mormonism. His elucidation of Christianity’s powerful role in shaping slavery and of a subsequent African spiritual “holocaust,” with its ironic result in African Christianization, is an especially fresh and incisive account.

Awash in a Sea of Faith reveals the proliferation of American religious expression—not its decline—and stresses the creative tensions between pulpit and pew across three hundred years of social maturation. Striking in its breadth and deeply rooted in primary sources, this seminal book recasts the landscape of American religious and cultural history.
