<p> <i>Landmarks of Tomorrow</i> forecasts changes in three major areas of human life and experience. The first part of the book treats the philosophical shift from a Cartesian universe of mechanical cause to a new universe of pattern, purpose, and process. Drucker discusses the power to organize men of knowledge and high skill for joint effort and performance as a key component of this change. The second part of the book sketches four realities that challenge the people of the free world: an educated society, economic development, the decline of government, and the collapse of Eastern culture. The final section of the book is concerned with the spiritual reality of human existence. These are seen as basic elements in late twentieth-century society. In his new introduction, Peter Drucker revisits the main findings of <i>Landmarks of Tomorrow</i> and assesses their validity in relation to today's concerns. It is a book that will be of interest to sociologists, economists, and political theorists.</p>
