"Never before has the peace question been dealt with by so bold, novel, and clear a method; never before has the financial interdependence of nations been shown with such precision.... It is refreshing to have demonstrated in this unsentimental, practical way the fact that as our financial interdependence increases war as a business venture necessarily becomes more and more unprofitable."
"Der Turmer" (Stuttgart).
"This demonstration should clear the air like a thunderstorm.... It is not because the book brilliantly expresses what are in many respects our own views that we urge its importance, but because of its unanswerable demonstration of the futility of military power in the economic field."
"Königsberger Allgemeine Zeitung."
"This book proves absolutely that conquest as a means of material gain has become an impossibility.... The author shows that the factors of the whole problem have been profoundly modified within the past forty years."
"Ethische Kultur" (Berlin).
"Never has militarism been combated by economic weapons with the skill shown by Norman Angell.... So broad and comprehensive a grasp of the moral as well as the economic force, that the book is a real pleasure to read.... The time was ripe for a man with this keenness of vision to come forward and prove in this flawless way that military power has nothing to do with national prosperity."
Professor Karl von Bar, the authority on International and Criminal Law, Privy Councillor, etc.
"Particularly do I agree with the author in these two points: (1) That in the present condition of organized society the attempt of one nation to destroy the commerce or industry of another must damage the victor more perhaps than the vanquished; and (2) that physical force is a constantly diminishing factor in human affairs. The rising generation seems to be realizing this more and more."
