The premise and conclusion of this proconsular series of lectures is that the world will be torn apart by war ""between left and right, between rich and poor"" unless ""the healing influence of the welfare state"" is applied on an international scale. Justice Douglas is particularly concerned with the underdeveloped nations, recommending ""some kind of federal relation"" with the developed ones, plus less exploitative aid and trade policies. His en passant discussions of world federalism are, however, so feeble that he himself seems to take them less than seriously. It is his characterization of the problems which energize the book. In lecturer's style, he relies on graphic examples (the continued existence of slavery, the slaughter and torture of Greeks, Indonesians and Guatemalans). While the U.S. uses its power to get ""vast material concessions rather than freedom,"" he concludes, ""the miserable and desperate condition of most of the people of the world promises revolution after revolution."" Nothing new here for world law advocates, but an appeal to both principle and self-interest which should unsettle the complacent and engage the sympathetic.
