The basis of the book, by this articulate journalist and historian, was the Walker-Ames Visiting Professor Lectures at the University of Washington in 1956. The book, subtitled An Inquiry into Freedom of the Press, is concerned with the conditions which make for, or work against the maintenance of a healthy public opinion of this country. Because ""In the U.S. the most important element in the circulatory system of ideas is the press"" the author sees as ""peril"" the fact that 81% of our communities have no ""opposition"" newspaper and that the resultant monopolistic publishers are often unwilling to accept the responsibilities of monopoly. But he sees ""promise"" in the American power of recovery from moral loss. The author considers instances of threat to freedom of the press and of speech and examines the American attitude toward the role of government and the uses of freedom. The book is short, lucid and eloquent. Of value to those who would be informed.
