Conversion is perhaps the most controversial subject in international religious freedom. Although the idea that people should be able freely to convert from one religion to another is widely accepted in the West, even among religious believers, it is not widely accepted elsewhere, especially in Muslim-majority countries, where conversion from Islam is often still illegal. In fact, although human rights advocates insist that the right to convert is part of international law, the status of the right is somewhat ambiguous.
In February, Penguin Random House will release a new history of conversion, Strange Gods: A Secular History of Conversion, by writer Susan Jacoby. Looks interesting, though grouping George W. Bush and Muhammad Ali together in the same category seems a little odd. Jacoby argues, among other things, that the idea of individual religious choice is a product of the secular Enlightenment–which may explain why the non-Western world is still deeply suspicious.
Here’s the publisher’s description:
In a groundbreaking historical work that addresses religious conversion in the West from an uncompromisingly secular perspective, Susan Jacoby challenges the conventional narrative of conversion as a purely spiritual journey. From the transformation on the road to Damascus of the Jew Saul into the Christian evangelist Paul to a twenty-first-century “religious marketplace” in which half of Americans have changed faiths at least once, nothing has been more important in the struggle for reason than the right to believe in the God of one’s choice or to reject belief in God altogether.
Focusing on the long, tense convergence of Judaism, Christianity, and Islam—each claiming possession of absolute truth—Jacoby examines conversions within a social and economic framework that includes theocratic coercion (unto torture and death) and the more friendly persuasion of political advantage, economic opportunism, and interreligious marriage. Moving through time, continents, and cultures—the triumph of Christianity over paganism in late antiquity, the Spanish Inquisition, John Calvin’s dour theocracy, Southern plantations where African slaves had to accept their masters’ religion—the narrative is punctuated by portraits of individual converts embodying the sacred and profane. The cast includes Augustine of Hippo; John Donne; the German Jew Edith Stein, whose conversion to Catholicism did not save her from Auschwitz; boxing champion Muhammad Ali; and former President George W. Bush. The story also encompasses conversions to rigid secular ideologies, notably Stalinist Communism, with their own truth claims.
Finally, Jacoby offers a powerful case for religious choice as a product of the secular Enlightenment. In a forthright and unsettling conclusion linking the present with the most violent parts of the West’s religious past, she reminds us that in the absence of Enlightenment values, radical Islamists are persecuting Christians, many other Muslims, and atheists in ways that recall the worst of the Middle Ages.
A provocative reassessment of the concept of an American golden age of European-born reason and intellectual curiosity in the years following the Revolutionary War:
A prominent figure in the Scottish Enlightenment, William Robertson differed from his contemporaries, such as Voltaire, Hume and Gibbon, because he used the critical tools of the Enlightenment to strengthen religion, not to attack it. As an historian, he helped shape 18th-century historiography. As a minister of the Church of Scotland, he sought to make the church fit for a polite age. And, as principal of the University of Edinburgh, he presided over a flourishing of intellectual inquiry in the midst of the Enlightenment. But despite his European fame, he was a controversial figure. Drawing extensively on his unpublished correspondence, Jeffrey Smitten captures both the man and his work in his own words. By foregrounding Robertson’s religious outlook, Smitten gives us a more contextualised and nuanced interpretation of Robertson’s motives, intentions and beliefs than we have had before.
social sciences in the nineteenth and early twentieth centuries. Without documents or memorials, these thinkers, he argues, employed conjecture to formulate a naturalistic account of society’s commercial and secular progression.
