The first book enquires into the origin of the rights of war and its different kinds, as also the extent of the power of Sovereigns: he explains in the second the nature and extent of those rights, whether public or private, whose violation authorises the taking up arms: in the third he treats of all that relates to the course of the war and the treaties of peace which put an end to it. The celebrated translator of Grotius and Puffendorf assures us that Grotius took the hint of attempting a system of natural law from Lord Bacon's works; and certainly, he adds, none was more proper for such an undertaking. A clear head, an excellent judgment, profound meditation, universal learning, prodigious reading, continual application to study amidst many distractions and the duties of several considerable places, together with a sincere love to truth, are qualities which cannot be denied to that great man without wronging our own judgment and giving room to suspect us of black envy or gross ignorance. It is said that he designed at first to give his book the title, of _The law of nature and of nations_; but afterwards preferred that which it now bears, _Of the rights of war and peace_. Never book met with such universal approbation: Commentaries have been written upon it by many learned men, and it has been publicly read at Universities. Though M. Barbeyrac thinks Puffendorf's book much more useful, he is at the same time persuaded that if Grotius had not led the way, we should not yet have had any tolerable system of natural law: "and, he adds, if Puffendorf had been in Grotius's place, and Grotius in Puffendorf's, the treatise _Of the rights of war and peace_ would in my opinion have been much more defective; and that _Of the law of nature and nations_ much more perfect." Puffendorf himself owns that there remained few things to be said after Grotius. Though the Latin language was at that time more used than at present, the principal nations of Europe wanted to have this work in their mother tongue. Grotius, on examining the Dutch translation, found the translator often wilfully deviating from the true sense of the original. The Great Gustavus caused it to be translated into Swedish: a translation of it into English was preparing in the year 1639: Mr. Barbeyrac thinks it was not finished in Grotius's life-time, but there have been two English translations of it since his death. It was first translated into German in 1707 by Mr. Schutz. The Leipsick journalists speak of this translation as very correct. There are two in French; one by Mr. Courtin, which that of Barbeyrac has totally eclipsed, and most justly: for never did a great author meet with a translator more worthy of him. Mr. Barbeyrac possessed all the necessary qualifications for executing properly such a difficult translation as that of the treatise _Of the rights of war and peace_.
