This is a very well-meaning book of some interest written in a popular style. It describes what the author quite properly calls the 'delusions' characteristic of the attitude of nations in their relations to one another. Knowing nothing of the early psychotic development in the individual the author naturally does not see how correct his diagnosis is and so thinks that these 'delusions' can be remedied by rather superficial measures of re-assurance and persuasion. There is no mention of psycho-analysis in the book. It is nevertheless a freshly written essay on a subject usually treated on stereotyped lines.
