Walden Two is a fictional outline of a modern utopia that has sparked controversy since its publication in 1948. Set in the United States, this book presents a society where human problems are resolved through a scientific technology of human conduct.

The narrative explores how great changes must be made in the American way of life. It discusses the challenges faced by society, such as consumption and pollution, and the need to address violence and chaos. The book poses a clear choice: either do nothing and face a potentially catastrophic future, or utilize our understanding of human behavior to create a productive and creative social environment for ourselves and future generations.
