Berger was a member of the Socialst party from Wisconsin who was elected to Congress in 1919 but was also under indictment for charges that he violated the Espionage Act. The committee decided against him and his seat was rescinded.

Amid the variety of human experiences, the comic occupies a distinctive place. It is simultaneously ubiquitous, relative, and fragile. In this book, Peter L. Berger reflects on the nature of the comic and its relationship to other human experiences. Berger contends that the comic is an integral aspect of human life, yet one that must be approached and analyzed circumspectly and circuitously. Beginning with an exploration of the anatomy of the comic, Berger addresses humor in philosophy, physiology, psychology, and the social sciences before turning to a discussion of different types of comedy and finally suggesting a theology of the comic in terms of its relationship to folly, redemption, and transcendence. Along the way, the reader is treated to a variety of jokes on a variety of topics, with particular emphasis on humor and its relationship to religion. Originally published in 1997, the second edition includes a new preface reflecting on Berger’s work in the intervening years, particularly on the relationship between humor and modernity.

A hundred years ago, any soapbox orator who called for women's suffrage, laws protecting the environment, an end to lynching, or a federal minimum wage was considered a utopian dreamer or a dangerous socialist. Now we take these ideas for granted -- because the radical ideas of one generation are often the common sense of the next. We all stand on the shoulders of earlier generations of radicals and reformers who challenged the status quo of their day. Unfortunately, most Americans know little of this progressive history. It isn't taught in most high schools. You can't find it on the major television networks. In popular media, the most persistent interpreter of America's radical past is Glenn Beck, who teaches viewers a wildly inaccurate history of unions, civil rights, and the American Left. The 100 Greatest Americans of the 20th Century, a colorful and witty history of the most influential progressive leaders of the twentieth century and beyond, is the perfect antidote.
