This brings together the various speeches and articles Wells has made dealing with his project for a World Encyclopedia, which should be a permanently fluid compilation of the essentials of world knowledge, by experts, for the average man. He presents it from different angles, with arguments pro and con. Then there is a lecture of the subject of modern education, what it lacks, where it should rebuild, and in this he outlines his specifications for essentials of knowledge, presumably the points on which the World Encyclopedia would be built. His contribution in the appendix on the subject of The Fall in America, 1937 is sure to arouse comment. More stimulating, at various points, than most of Wells recent publications, and the phenomenal success of his lecture trip last fall insures a favorable reception among those who heard him. Some of the material has appeared in periodicals; some of the lectures seem repetitive, as he presents his plan to American audiences, to English, to French. This will somewhat limit the sale of the book.
