"The more our commercial system gains in complication, the more does the common prosperity of us all come to depend upon the due performance of all contracts. Commercial development is broadly illustrating one profound truth: that the real basis of social morality is self-interest. If the subject of rivalry between nations is business, the code which has come to dominate business must necessarily come to dominate the conduct of governments."

“The convictions of the multitudes — and on certain points like the desirability of organizing the world on a nationalist basis there is overwhelming agreement — are sincere convictions. They are, as we know, sometimes disastrously erroneous; but they are also disastrously honest. The Nationalisms, the Protectionisms, the Mercantilisms and all the other fallacies which rack Europe and create the chaos are sincerely held fallacies. They are, to these multitudes, the truth, and the prophet who denies them shall be stoned.”

“To shut our eyes to the part that John Smith plays in the perpetuation of unworkable policies, in building up the forces of which he becomes the victim, is to perpetuate his victimization. The only means by which he can be liberated from the evil power of organized minorities is by making him aware of the nature of the impulses and motives to which the exploiters so successfully appeal. If such phenomena as nationalism, for instance, can assume forms that are gravely dangerous, it is because the nationalist appeal finds response in deep human impulses, instincts, in psychological facts which we must face.”

“I doubt whether the public has fully grasped the change which has come over the nature of modern wealth. If the nature of that change were grasped by our publics, we should be much nearer to accepting the international organizations necessary for the defense of welfare and of civilization than we are. As it is, we are in danger of being diverted to the discussion of schemes for a vast rearrangement of frontiers in defiance of national feeling — for the boundaries of the national and the economic unit do not conveniently coincide — before which the difficulties of a Disarmament Conference would pale into insignificance.”

“I would not hesitate to say that nine out of ten of the critics of the peace movement get the argument turned upside down. "You cannot change human nature" has become a sort of incantation with those critics. Perhaps you cannot "change human nature" — I don't indeed know what the phrase means. But you can certainly change human behavior, which is what matters, as the whole panorama of history shows.”

“So long as an individual, whether person or state, has only his own arms to depend upon in order to defend his rights by arms, then he must be stronger than anyone likely to challenge those rights. Which means that that other is deprived of similar defense. Within the frontiers man long ago made the discovery that the only way out of that dilemma is for the community, by putting its combined power behind a protective law, to assume the defense of the individual. Defense must be a communal, a collective function, or it cannot exist effectively at all.”

“Within the state we have made defense of the individual the obligation of the whole community, and by that fact have established such preponderance of power on the side of the law that it could never be good business to challenge it. And that fact has, in large measure, swept highwaymen from the roads and pirates from the seas.”
