An incisive argument for the relevance of political philosophy and its possibility of effecting change.

The appeal of political philosophy is that it will answer questions about justice for the sake of political action. But contemporary political philosophy struggles to live up to this promise. Since the death of John Rawls, political philosophers have become absorbed in methodological debates, leading to an impasse between two unattractive tendencies: utopians argue that philosophy should focus uncompromisingly on abstract questions of justice, while pragmatists argue that we should concern ourselves only with local efforts to ameliorate injustice. Agents of Change shows a way forward.

Ben Laurence argues that we can combine utopian justice and the pragmatic response to injustice in a political philosophy that unifies theory and practice in pursuit of change. Political philosophy, on this view, is not a purely normative theory disconnected from practice. Rather, political philosophy is itself a practice—an exercise of practical reason issuing in action. Laurence contends that this exercise begins in ordinary life with the confrontation with injustice. Philosophy draws ideas about justice from this encounter to be pursued through political action. Laurence shows that the task of political philosophy is not complete until it asks the question “What is to be done?” and deliberates actionable answers.

Why did the Chinese party state collapse so quickly after the onset of the Cultural Revolution? The award-winning author of China Under Mao offers a surprising answer that holds a powerful implicit warning for today’s governments.

By May 1966, just seventeen years after its founding, the People’s Republic of China had become one of the most powerfully centralized states in modern history. But that summer everything changed. Mao Zedong called for students to attack intellectuals and officials who allegedly lacked commitment to revolutionary principles. Rebels responded by toppling local governments across the country, ushering in nearly two years of conflict that in places came close to civil war and resulted in nearly 1.6 million dead.

How and why did the party state collapse so rapidly? Standard accounts depict a revolution instigated from the top down and escalated from the bottom up. In this pathbreaking reconsideration of the origins and trajectory of the Cultural Revolution, Andrew Walder offers a startling new conclusion: party cadres seized power from their superiors, setting off a chain reaction of violence, intensified by a mishandled army intervention. This inside-out dynamic explains how virulent factions formed, why the conflict escalated, and why the repression that ended the disorder was so much worse than the violence it was meant to contain.

Based on over 2,000 local annals chronicling some 34,000 revolutionary episodes across China, Agents of Disorder offers an original interpretation of familiar but complex events and suggests a broader lesson for our times: forces of order that we count on to stanch violence can instead generate devastating bloodshed.

In this sweeping reinterpretation of American political culture, James Block offers a new perspective on the formation of the modern American self and society. Block roots both self and society in the concept of agency, rather than liberty, and dispenses with the national myth of the "sacred cause of liberty"--with the Declaration of Independence as its "American scripture." Instead, he recovers the early modern conception of agency as the true synthesis emerging from America's Protestant and liberal cultural foundations.

Block traces agency doctrine from its pre-Commonwealth English origins through its development into the American mainstream culture on the eve of the twentieth century. The concept of agency that prevailed in the colonies simultaneously released individuals from traditional constraints to participate actively and self-reliantly in social institutions, while confining them within a new set of commitments. Individual initiative was now firmly bounded by the modern values and ends of personal Protestant religiosity and collective liberal institutional authority. As Block shows, this complex relation of self to society lies at the root of the American character.

A Nation of Agents is a new reading of what the "first new nation" did and did not achieve. It will enable us to move beyond long-standing national myths and grasp both the American achievement and its legacy for modernity.

Viruses are the most abundant biological entities on Earth, and arguably the most successful. They are not technically alive, but—as infectious vehicles of genetic information—they have a remarkable capacity to invade, replicate, and evolve within living cells. Synthesizing a large body of recent research, Michael Cordingley goes beyond our familiarity with viral infections to show how viruses spur evolutionary change in their hosts, shape global ecosystems, and influence every domain of life.

In the last few decades, research has revealed that viruses are fundamental to the photosynthetic capacity of the world’s oceans and the composition of the human microbiome. Perhaps most fascinating, viruses are now recognized as remarkable engines of the genetic innovation that fuels natural selection and catalyzes evolution in all domains of life. Viruses have coevolved with their hosts since the beginning of life on our planet and are part of the evolutionary legacy of every species that has ever lived.

Cordingley explains how viruses are responsible for the creation of many feared bacterial diseases and the emergence of newly pathogenic and drug-resistant strains. And as more and more viruses jump to humans from other animals, new epidemics of viral disease will threaten global society. But Cordingley shows that we can adapt, relying on our evolved cognitive and cultural capacities to limit the consequences of viral infections. Piecing together the story of viruses’ major role within and beyond human disease, Viruses creates a valuable roadmap through the rapidly expanding terrain of virology.
