In the first three chapters of this book the elements of persuasion as a mental process are distinguished, and various forms of false persuasion in individuals and groups are described; it is shown how, from the very nature of the process involved, our persuasion of ourselves is only too apt to degenerate into self-deception, and how our persuasion of others may eaily assume the form of a deliberate attempt to exploit their mental or moral weaknesses. Chapter IV indicates how the tendencies of false persuasion may be counteracted, and on what lines persuasion may be rightly directed. Up to this point the subject is treated mainly in its psychological aspect. The subsequent chapters, which are closely related to, and follow naturally, the study of persuasion as a mental process, deal with persuasion more exclusively as a form of expression. In this part of the book special attention is given to such modern forms of propaganda as advertisements, newspapers, the cinematograph, the novel and the drama.

The time has gone by when any one man could hope to write an adequate text book of psychology. The science has now so many branches, so many methods, so many fields of application, and such an immense mass of data of observation is now on record, that no one man can hope to have the necessary familiarity with the whole. But, even when a galaxy of learning and talent shall have written the text book of the future, there will still be need for the book which will introduce the student to his science, which will aim at giving him at the outset of his studies a profitable line of approach, a fruitful way of thinking of psychological problems, and a terminology as little misleading as possible. The present volume is designed to render these services.

John Maynard Keynes, then a rising young economist, participated in the Paris Peace Conference in 1919 as chief representative of the British Treasury and advisor to Prime Minister David Lloyd George. He resigned after desperately trying and failing to reduce the huge demands for reparations being made on Germany. The Economic Consequences of the Peace is Keynes' brilliant and prophetic analysis of the effects that the peace treaty would have both on Germany and, even more fatefully, the world.
