Nineteen scientists, doctors and philosophers share their perspective on what is arguably the most significant scientific development that humanity has ever faced - the eradication of aging and mortality. This anthology is both a gentle introduction to the multitude of cutting-edge scientific developments, and a thoughtful, multidisciplinary discussion of the ethics, politics and philosophy behind the scientific conquest of aging.

Who Leads Whom? is an ambitious study that addresses some of the most important questions in contemporary American politics: Do presidents pander to public opinion by backing popular policy measures that they believe would actually harm the country? Why do presidents "go public" with policy appeals? And do those appeals affect legislative outcomes? 

Analyzing the actions of modern presidents ranging from Eisenhower to Clinton, Brandice Canes-Wrone demonstrates that presidents' involvement of the mass public, by putting pressure on Congress, shifts policy in the direction of majority opinion. More important, she also shows that presidents rarely cater to the mass citizenry unless they already agree with the public's preferred course of action. With contemporary politics so connected to the pulse of the American people, Who Leads Whom? offers much-needed insight into how public opinion actually works in our democratic process. Integrating perspectives from presidential studies, legislative politics, public opinion, and rational choice theory, this theoretical and empirical inquiry will appeal to a wide range of scholars of American political processes.

Prior to the First World War, more people learned of evolutionary theory from the voluminous writings of Charles Darwin’s foremost champion in Germany, Ernst Haeckel (1834–1919), than through any other source, including the writings of Darwin himself. Haeckel’s books vastly outsold Darwin’s in their own time, and today, his extraordinary scientific illustrations adorn books, posters, and coffee mugs.  Haeckel gave currency to the idea of the “missing link” between apes and man, formulated the concept of ecology, and promulgated the “biogenetic law”—the idea that the embryo of an advanced species recapitulates the stages the species went through in its evolutionary descent. But, with detractors ranging from paleontologist Stephen Jay Gould to modern-day creationists and advocates of Intelligent Design, Haeckel is better known as a divisive figure than as a pioneering biologist. Robert J. Richards’s intellectual biography rehabilitates Haeckel, providing the most accurate measure of his science and art yet written, as well as a moving account of Haeckel’s eventful life.  

            The Tragic Sense of Life examines the intellectual context as well as the intimate experiences and profound convictions that allowed Darwin’s message to become almost a religious calling for Haeckel. Far from shying away from the many controversies that marked Haeckel’s life and career, Richards engages Haeckel’s many challengers and dissenters, whose accusations against him range from the charge that he falsified some of his famous drawings to the supposedly proto-Nazi quality of his biological theories. Reappraising Haeckel’s accomplishments, artistic endeavors, many battles, personal relationships, and searing loves, Richards convincingly demonstrates the enormous impact Haeckel had on biology and larger scientific affairs during the last half of the nineteenth and early part of the twentieth centuries. 

The definitive account of Darwin’s greatest intellectual heir, The Tragic Sense of Life book is a sweeping reevaluation of the Romantic ideas and calamitous biography of a man whose vision of evolutionary theory is still influential today.
