Modernity was supposed to usher in a rational secular world where religion was marginalized. Some even predicted it would disappear. But religion has not only survived—it is growing and thriving in the modern world. Defying predictions, we live today in a world of plurality where diverse groups live under conditions of civic peace and in social interaction. However, this arrangement is not without tensions. How do we handle moral issues, such as abortion or homosexuality, when different groups have strongly held but opposing viewpoints? And how does culture maintain its harmony when confronted with the challenge of an aggressive fundamentalism?

The answer, according to world-renowned sociologists Peter Berger and Anton Zijderveld, is doubt. Not the stupefying doubt of relativism where we become incapable of any decision because we are overwhelmed by options, but a virtuous use of doubt that allows us to move forward boldly with strong moral convictions without caving in to the fanatic's temptation of seeing everyone who disagrees with you as the enemy. How we as individuals and as a society can find this ideal balance is the subject of this deceptively simple but revolutionary work.

In Praise of Doubt takes the reader on an exciting whirlwind tour of the history of modernity, religion, the rise of psychology, Marxism, and the intellectual challenge of relativism, the failure of totalitarianism, fundamentalism as a modern invention, and the startling conclusion explaining why truth, even religious truth, needs doubt to survive and thrive.

Peter L. Berger is an internationally renowned sociologist and faculty member at Boston University, where in 1985 he founded its Institute of Culture, Religion, and World Affairs. He is the author of many books, among them The Social Construction of Reality, The Homeless Mind, and Questions of Faith.
