be called De Jure Belli, but there is scarcely any subject of international law which he leaves untouched. He obtained, moreover, a general recognition for the doctrine of the Law of Nature which exerted so strong an influence upon succeeding centuries; indeed, between these two sciences, as between international law and ethics, he draws no very sharp line of demarcation, although, on the whole, in spite of an unscientific, scholastic use of quotation from authorities, his treatment of the

"the position that the Jus Gentium and the Jus Naturæ were identical, Grotius, with his immediate predecessors and his immediate successors, attributed to the Law of Nature an authority which would never perhaps have been claimed for it, if "Law of Nations" had not in that age been an ambiguous expression. They laid down unreservedly that Natural Law is the code of states, and thus put in operation a process which has continued almost down to our own day, the process of engrafting on the international system rules which are supposed to have been evolved from the unassisted contemplation of the conception of Nature. There is, too, one consequence of immense practical importance to mankind which, though not unknown during the early modern history of Europe, was never clearly or universally acknowledged till the doctrines of the Grotian school had prevailed. If the society of nations is governed by Natural Law, the atoms which compose it must be absolutely equal. Men under the sceptre of Nature are all equal, and accordingly commonwealths are equal if the international state be one of nature. The proposition that independent communities, however different in size and power, are all equal in the view of the Law of Nations, has largely contributed to the happiness of mankind, though it is constantly threatened by the political tendencies of each successive age. It is a doctrine which probably would never have obtained a secure footing at all if International Law had not been entirely derived from the majestic claims of Nature by the I'ublicists who wrote after the revival of letters." (Op. cit., p. 100.)

done away with: Grotius accepts it as fact, * (as Hobbes did later) as the natural method for settling the disputes which were bound constantly to arise between so many independent and sovereign nations. A terrible scourge it must ever remain, but as the only available form of legal procedure, it is sanctioned by the practice of states and not less by the law of nature and of nations. Grotius did not advance beyond this position. Every violation of the law of nations can be settled but in one way-by war, the force of the stronger.

The necessary distinction between law and ethics. was drawn by Puffendorf, † a successor of Grotius who gave an outwardly systematic form to the doctrine of the great jurist, without adding to it

* Grotius, however, is a painstaking student of Scripture, and is willing to say something in favour of peace—not a permanent peace, that is to say, the idea of which would scarcely be likely to occur to anyone in the early years of the seventeenth century-but a plea for fewer, shorter wars. "If therefore," he says, "a peace sufficiently safe can be had, it is not ill secured by the condonation of offenses, and damages, and expenses: especially among Christians, to whom the Lord has given his peace as his legacy. And so St. Paul, his best interpreter, exhorts us to live at peace with all May God write these lessons-He who alone can—on the hearts of all those who have the affairs of Christendom in their hands." (De Jure Belli et Pacis, III. Ch. XXV., Whewell's translation.)

See also op. cit., II., Ch. XXIII., Sect. VIII, where Grotius recommends that Congresses of Christian Powers should be held with a view to the peaceful settlement of international differences.

† Puffendorf's best known work, De Jure Naturæ et Gentium, was published in 1672.

They are, in the first place, a friendly conciliatory attitude; and secondly, such means of settlement as mediation, arbitration and Peace Congresses. These are the refuges of a peace-loving nation, in cases where vital interests are not at stake. " Nature gives us no right to use force, except where mild and conciliatory measures are useless." (Law of Nations, II. Ch. xviii. § 331.) "Every power owes it in this matter to the happiness of human society to show itself ready for every means of reconciliation, in cases where the interests at stake are neither vital nor important." (ibid. § 332.) At the same time, it is never advisable that a nation should forgive an insult which it has not the power

to resent.

The Dream of a Perpetual Peace.

But side by side with this development and gradual popularisation of the new science of International Law, ideas of a less practical, but not less fruitful kind had been steadily making their way and obtaining a strong hold upon the popular mind. The Decree of Eternal Pacification of 1495 had abolished private war, one of the heavy curses of the Middle Ages. Why should it not be extended to banish warfare between states as well? Gradually one proposal after another was made.
