to the English border, unchained them, and hurried them adrift into the wilderness, saying--Now, boys, shift for yourselves, and henceforth plunder none but Englishmen. What I deduce from all this is, that as the feuds arising between individuals under the relation of neighbors, are so far from tending to a hostile result, that, on the contrary, as coming under a rule of law already ascertained, or furnishing the basis for a new rule, they gradually tighten the cords which exclude all opening for quarrel; not otherwise is the result, and therefore the usefulness, of war amongst nations. All the causes of war, the occasions upon which it is likely to arise, the true and the ostensible motives, are gradually evolved, are examined, searched, valued, by publicists; and by such means, in the further progress of men, a comprehensive law of nations will finally be accumulated, not such as now passes for international law, (a worthless code that _has_ no weight in the practice of nations, nor deserves any,) but one which will exhaust the great body of cases under which wars have arisen under the Christian era, and gradually collect a public opinion of Christendom upon the nature of each particular case. The causes that _have_ existed for war are the causes that _will_ exist; or, at least, they are the same under modifications that will simply vary the rule, as our law cases in the courts are every day circumstantiating the particular statute concerned. At this stage of advance, and when a true European opinion has been created, a '_sensus communis_,' or community of feeling on the main classifications of wars, it will become possible to erect a real Areopagus, or central congress for all Christendom, not with any commission to suppress wars,--a policy which would neutralize itself by reacting as a fresh cause of war, since high-spirited nations would arm for the purpose of resisting such decrees; but with the purpose and the effect of oftentimes healing local or momentary animosities, and also by publishing the opinion of Europe, assembled in council, with the effect of taking away the shadow of dishonor from the act of retiring from war. Not to mention that the mere delay, involved in the waiting for the solemn opinion of congress, would always be friendly to pacific councils. But _would_ the belligerents wait? That concession might be secured by general exchange of treaties, in the same way that the cooperation of so many nations has been secured to the suppression of the trade in slaves. And one thing is clear, that when all the causes of war, involving _manifest_ injustice, are banished by the force of European opinion, focally converged upon the subject, the range of war will be prodigiously circumscribed. The costliness of war, which, for various reasons has been continually increasing since the feudal period, will operate as another limitation upon its field, concurring powerfully with the public declaration from a council of collective
