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.

"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
