The late Robert A. Dahl was Sterling Professor Emeritus of Political Science at Yale University. Ian Shapiro is Sterling Professor of Political Science at Yale University, where he also serves as Henry R. Luce Director of the MacMillan Center for International and Area Studies.

Written by the preeminent democratic theorist of our time, this book explains the nature, value, and mechanics of democracy. This new edition includes two additional chapters by Ian Shapiro, Dahl’s successor as Sterling Professor of Political Science at Yale and a leading contemporary authority on democracy. One chapter deals with the prospects for democracy in light of developments since the advent of the Arab spring in 2010. The other takes up the effects of inequality and money in politics on the quality of democracy, a subject that was of increasing concern to Dahl in his final years.

“The late Robert Dahl’s On Democracy is the source for how to govern democratically. Following the methods and channeling the insight of Dahl, Ian Shapiro’s new edition completes Dahl’s project and is must reading for the next generation and essential re-reading for the present.”—Michael Doyle, Columbia University

“Dahl’s tersest summary of the lessons of his profoundly influential interrogation of democracy’s strengths and weaknesses. Ian Shapiro shows forcefully what we have learned since its initial publication.”—John Dunn, author of Breaking Democracy’s Spell

“Robert A. Dahl’s On Democracy admirably synthesized the contributions of the world’s leading democratic theorist of the twentieth century. Now Ian Shapiro intelligently carries Dahl’s queries and concerns into our own century.”—Robert D. Putnam, author of Our Kids: The American Dream in Crisis
