A foundational work on historical and social studies of quantification What accounts for the prestige of quantitative methods? The usual answer is that quantification is desirable in social investigation as a result of its successes in science. Trust in Numbers questions whether such success in the study of stars, molecules, or cells should be an attractive model for research on human societies, and examines why the natural sciences are highly quantitative in the first place. Theodore Porter argues that a better understanding of the attractions of quantification in business, government, and social research brings a fresh perspective to its role in psychology, physics, and medicine. Quantitative rigor is not inherent in science but arises from political and social pressures, and objectivity derives its impetus from cultural contexts. In a new preface, the author sheds light on the current infatuation with quantitative methods, particularly at the intersection of science and bureaucracy.

"The time has come now," Abraham Lincoln told his cabinet as he presented the preliminary draft of a "Proclamation of Emancipation." Lincoln's effort to end slavery has been controversial from its inception-when it was denounced by some as an unconstitutional usurpation and by others as an inadequate half-measure-up to the present, as historians have discounted its import and impact. At the sesquicentennial of the Emancipation Proclamation, Louis Masur seeks to restore the document's reputation by exploring its evolution. Lincoln's Hundred Days is the first book to tell the full story of the critical period between September 22, 1862, when Lincoln issued his preliminary Proclamation, and January 1, 1863, when he signed the final, significantly altered, decree. In those tumultuous hundred days, as battlefield deaths mounted, debate raged. Masur commands vast primary sources to portray the daily struggles and enormous consequences of the president's efforts as Lincoln led a nation through war and toward emancipation. With his deadline looming, Lincoln hesitated and calculated, frustrating friends and foes alike, as he reckoned with the anxieties and expectations of millions. We hear these concerns, from poets, cabinet members and foreign officials, from enlisted men on the front and free blacks as well as slaves. Masur presents a fresh portrait of Lincoln as a complex figure who worried about, listened to, debated, prayed for, and even joked with his country, and then followed his conviction in directing America toward a terrifying and thrilling unknown.
