The Lonely Crowd is considered by many to be the most influential book of the twentieth century. Its now-classic analysis of the “new middle class” in terms of inner-directed and other-directed social character opened exciting new dimensions in our understanding of the psychological, political, and economic problems that confront the individual in contemporary American society. The 1969 abridged and revised edition of the book is now reissued with a new foreword by Todd Gitlin that explains why the book is still relevant to our own era.
