“So likewise, a passionate attachment of one Nation for another produces a variety of evils. Sympathy for the favorite Nation, facilitating the illusion of an imaginary common interest, in cases where no real common interest exists, and infusing into one the enmities of the other, betrays the former into a participation in the quarrels and wars of the latter, without adequate inducement or justification. It leads also to concessions to the favorite Nation of privileges denied to others, which is apt doubly to injure the Nation making the concessions; by unnecessarily parting with what ought to have been retained; and by exciting jealousy, ill-will, and a disposition to retaliate, in the parties from whom equal privileges are withheld. And it gives to ambitious, corrupted, or deluded citizens, (who devote themselves to the favorite nation,) facility to betray or sacrifice the interests of their own country, without odium, sometimes even with popularity; gilding, with the appearances of a virtuous sense of obligation, a commendable deference for public opinion, or a laudable zeal for public good, the base or foolish compliances of ambition, corruption, or infatuation.”

Context: In all cases where a majority are united by a common interest or passion, the rights of the minority are in danger. What motives are to restrain them? A prudent regard to the maxim that honesty is the best policy is found by experience to be as little regarded by bodies of men as by individuals. Respect for character is always diminished in proportion to the number among whom the blame or praise is to be divided. Conscience, the only remaining tie, is known to be inadequate in individuals: In large numbers, little is to be expected from it. Besides, Religion itself may become a motive to persecution & oppression. — These observations are verified by the Histories of every Country antient & modern. In Greece & Rome the rich & poor, the creditors & debtors, as well as the patricians & plebians alternately oppressed each other with equal unmercifulness. What a source of oppression was the relation between the parent cities of Rome, Athens & Carthage, & their respective provinces: the former possessing the power, & the latter being sufficiently distinguished to be separate objects of it? Why was America so justly apprehensive of Parliamentary injustice? Because G. Britain had a separate interest real or supposed, & if her authority had been admitted, could have pursued that interest at our expence. We have seen the mere distinction of colour made in the most enlightened period of time, a ground of the most oppressive dominion ever exercised by man over man. What has been the source of those unjust laws complained of among ourselves? Has it not been the real or supposed interest of the major number? Debtors have defrauded their creditors. The landed interest has borne hard on the mercantile interest. The Holders of one species of property have thrown a disproportion of taxes on the holders of another species. The lesson we are to draw from the whole is that where a majority are united by a common sentiment, and have an opportunity, the rights of the minor party become insecure. In a Republican Govt. the Majority if united have always an opportunity. The only remedy is to enlarge the sphere, & thereby divide the community into so great a number of interests & parties, that in the 1st. place a majority will not be likely at the same moment to have a common interest separate from that of the whole or of the minority; and in the 2d. place, that in case they shd. have such an interest, they may not be apt to unite in the pursuit of it. It was incumbent on us then to try this remedy, and with that view to frame a republican system on such a scale & in such a form as will controul all the evils wch. have been experienced.

Context: And numerous people whose families belong to the peasantry and working classes are now filling prominent positions in this National Socialist State. Some of them actually hold the highest offices in the leadership of the nation, as Cabinet Ministers, Reichsstatthalter and Gauleiter. But National Socialism always bears in mind the interests of the people as a whole and not the interests of one class or another. The National Socialist Revolution has not aimed at turning a privileged class into a class which will have no rights in the future. Its aim has been to grant equal rights to those social strata that hitherto were denied such rights.

Address to the United Nations (1963)
Context: The United Nations continues to sense as the forum where nations whose interests clash may lay their cases before world opinion. It still provides the essential escape valve without which the slow build-up of pressures would have long since resulted in catastrophic explosion.
