This article analyzes today's global values crisis as a matter of both personal and institutional failure. Social disintegration constitutes humanity's greatest challenge at the turn of the millennium. A viable future requires a new social project which embodies a new ethos—one which includes both traditional and liberal values and which avoids their vices along with the traps of authoritarian socialism. In order to spell out this new social project, the article describes the essential features of the traditional ethos and the liberal ethos: their economies, the understanding of nature, religion, history, politics, and ethics. This article argues that the needed participatory radical ethos incarnates Christian values for our time.
