The editors have chosen substantial excerpts from the essential theorists of the past, including Jean-Jacques Rousseau, John Stuart Mill, Alexis de Tocqueville, and the authors of The Federalist Papers ; they place them side by side with the work of such influential modern scholars as Joseph Schumpeter, Adam Przeworski, Seymour Martin Lipset, Samuel P. Huntington, Ronald Dworkin, and Amartya Sen. The book is divided into nine self-contained chapters: "Defining Democracy," which discusses procedural, deliberative, and substantive democracy; "Sources of Democracy," on why democracy exists in some countries and not in others; "Democracy, Culture, and Society," about cultural and sociological preconditions for democracy; "Democracy and Constitutionalism," which focuses on the importance of independent courts and a bill of rights; "Presidentialism versus Parliamentarianism"; "Representation," discussing which is the fairest system of democratic accountability; "Interest Groups"; "Democracy's Effects," an examination of the effect of democracy on economic growth and social inequality; and finally, "Democracy and the Global Order" discusses the effects of democracy on international relations, including the propensity for war and the erosion of national sovereignty by transnational forces.DemocracyDemocracy.321.8Dahl Robert Alan1915-120901Shapiro Ian549030Cheibub Jose Antonio1867933MiAaPQMiAaPQMiAaPQBOOK9910974529603321The democracy sourcebook4475697UNINA
