Dr. Friedrich Curtius.
"The book will, I hope, convince everyone that in our time the attempt to settle industrial and commercial conflicts by arms is an absurdity.... I doubt, indeed, whether educated folks in Germany entertain this 'illusion' ... or the idea that colonies or wealth can be 'captured.' ... A war dictated by a moral idea, the only one we can justify, is inconceivable as between England and Germany."
Dr. Wilhelm Ostwald, who has occupied chairs in several German Universities, as well as at Harvard and Columbia.
"From the first line to the last 'The Great Illusion' expresses my own opinions."
Dr. Sommer, Member of the Reichstag.
"A most timely work, and one which everyone, be he statesman or political economist, should study ... especially if he desires to understand a peace ideal which is practical and realizable.... Without agreeing on all points, I admit gladly the force and suggestiveness of the thesis.... We on our side should make it our business, as you should on yours, to render it operative, to use the means, heretofore unrealized, of joint work for civilization. In rendering possible such joint work, Norman Angell's book must take a foremost place."
Dr. Max Nordau.
"If the destiny of people were settled by reason and interest, the influence of such a book would be decisive.... The book will convince the far-seeing minority, who will spread the truth, and thus slowly conquer the world."
Dr. Albert Suedekum, Member of the Reichstag, author of several works on municipal government, editor of Municipal Year-Books, etc.
"I consider the book an invaluable contribution to the better understanding of the real basis of international peace."
