In Going to Extremes, renowned legal scholar and best-selling author Cass R. Sunstein offers startling insights into why and when people gravitate toward extremism. Sunstein marshals a wealth of evidence that shows that when like-minded people gather in groups, they tend to become more extreme in their views than they were before. Thus when liberals group get together to debate climate change, they end up more alarmed about climate change, while conservatives brought together to discuss same-sex unions become more set against same-sex unions. In courtrooms, radio stations, and chatrooms, enclaves of like-minded people are breeding ground for extreme movements. Indeed, Sunstein shows that a good way to create an extremist group, or a cult of any kind, is to separate members from the rest of society, either physically or psychologically. Sunstein's findings help to explain such diverse phenomena as political outrage on the Internet, unanticipated "blockbusters" in the film and music industry, the success of the disability rights movement, ethnic conflict in Iraq and former Yugoslavia, and Islamic terrorism.

Providing a wealth of real-world examples—sometimes entertaining, sometimes alarming—Sunstein offers a fresh explanation of why partisanship has become so bitter and debate so rancorous in America and abroad.

Among these small, reflective sketches are unforgettable encounters with the members of Hemingway's slightly rag-tag circle of artists and writers, some also fated to achieve fame and glory, others to fall into obscurity. Here, too, is an evocation of the Paris that Hemingway knew as a young man - a map drawn in his distinct prose of the streets and cafes and bookshops that comprised the city in which he, as a young writer, sometimes struggling against the cold and hunger of near poverty, honed the skills of his craft.

A Moveable Feast is at once an elegy to the remarkable group for expatriates that gathered in Paris during the twenties and a testament to the risks and rewards of the writerly life.
