Can religious diversity really create a more robust democracy? In Why Religion Is Good for American Democracy (Princeton University Press), Wuthnow argues it does. He explains how religion benefits democracy by creating spirited competition and debate among groups with closely held beliefs, bringing alternative, innovative perspectives to the table. At a time when some observers believe American democracy to be in dire need of revitalization, Wuthnow’s book illustrates how religious groups contribute to this goal despite the nation’s ongoing challenges.
