Now, what are the agencies which operate in producing the frame of mind which makes people ready to go to war on small provocation? It is at these the friends of peace must strike, in time of peace, and not after the cannon has begun to roar and the country has gone mad with patriotism and rage. They are, first of all, the preaching in the press and elsewhere of the false and pernicious doctrine that one nation gains by another's losses, and can be made happy by its misery; that the United States, for instance, profits in the long run by the prostration of French, German, or English industry. One of the first duties of a peace society is to watch this doctrine, and hunt it down wherever they see it, as one of the great promoters of the pride and hardness of heart which make war seem a trifling evil. America can no more gain by French or German ruin than New York can gain by that of Massachusetts. Secondly, there is the mediaeval doctrine that the less commercial intercourse nations carry on with each other the better for both, and that markets won or kept by force are means of gain. There has probably been no more fruitful source of war than this. It has for three centuries desolated the world, and all peace associations should fix on it, wherever they encounter it, the mark of the beast. Thirdly, there is the tendency of the press, which is now the great moulder of public opinion, to take what we may call the pugilist's view of international controversies. The habit of taunting foreign disputants, sneering at the cowardice or weakness of the one who shows any sign of reluctance in drawing the sword, and counting up the possible profit to its own country of one or other being well thrashed, in which it so frequently indulges, has inevitably the effect not only of goading the disputants into hostilities, but of connecting in the popular mind at home the idea of unreadiness or unwillingness to fight with baseness and meanness and material disadvantage. Fourthly, there is the practice, to which the press, orators, and poets in every civilized country steadily adhere, of maintaining, as far as their influence goes, the same notions about national honor which once prevailed about individual "honor"--that is, the notion that it is discreditable to acknowledge one's self in the wrong, and always more becoming to fight than apologize. "The code" has been abandoned in the Northern States and in England in the regulations of the relations of individual men, and a duellist is looked on, if not as a wicked, as a crack-brained person; but in some degree in both of them, and in a great degree in all other countries, it still regulates the mode in which international quarrels are brought to a conclusion.
