was far from my wish to intrude. It appeared to me that a course of lectures on another science closely connected with all liberal professional studies, and which had long been the subject of my own reading and reflection, might not only prove a most useful introduction to the law of England, but might also become an interesting part of general study, and an important branch of the education of those who were not destined for the profession of the law. I was confirmed in my opinion by the assent and approbation of men, whose names, if it were becoming to mention them on so slight an occasion, would add authority to truth, and furnish some excuse even for error. Encouraged by their approbation, I resolved without delay to commence the undertaking, of which I shall now proceed to give some account; without interrupting the progress of my discourse by anticipating or answering the remarks of those who may, perhaps, sneer at me for a departure from the usual course of my profession; because I am desirous of employing in a rational and useful pursuit

that leisure, of which the same men would have required no account, if it had been wasted on trifles, or even abused in dissipation.

The science which teaches the rights and duties of men and of states, has, in modern times, been called the Law of Nature and Nations. Under this comprehensive title are included the rules of morality, as they prescribe the conduct of private men towards each other in all the various relations of human life; as they regulate both the obedience of citizens to the laws, and the authority of the magistrate in framing laws and administering government; as they modify the intercourse of independent commonwealths in peace, and prescribe limits to their hostility in war. This important science comprehends only that part of private ethics which is capable of being reduced to fixed and general rules. It considers only those general principles of jurisprudence and politics which the wisdom of the lawgiver adapts to the peculiar situation of his own country, and which the skill of the statesman applies to the more

fluctuating and infinitely varying circumstances which affect its immediate welfare "For there are in nature certain

and safety.

fountains of justice whence all civil laws are derived, but as streams; and like as waters do take tinctures and tastes from the soils through which they run, so do civil laws vary according to the regions and governments where they are planted, though they proceed from the same fountains."*. Bacon's Dig. and Adv. of Learn. Works, vol. i. p. 101.

On the great questions of morality, of politics, and of municipal law, it is the object. of this science to deliver only those fundamental truths of which the particular application is as extensive as the whole private and public conduct of men; to discover those "fountains of justice," without pursuing the "streams" through the endless variety of

their course. But another part of the subject is treated with greater fulness and minuteness of application; namely, that important branch of it which professes to regulate the relations and intercourse of states, and more especially, both on account of their greater perfection and their more immediate reference to use, the regulations of that intercourse as they are modified by the usages of the civilised nations of Christendom. Here this science no longer rests in general principles. That province of it which we now call the law of nations, has, in many of its parts, acquired among our European nations much of the precision and certainty of positive law, and the particulars of that law are chiefly to be found in the works of those writers who have treated the science of which I now speak. It is because they have classed (in a manner which seems peculiar to modern times) the duties of individuals with those of nations, and established their obligation on similar grounds, that the whole science has been called, "The Law of Nature and Nations."

Whether this appellation be the happiest

that could have been chosen for the science, and by what steps it came to be adopted among our modern moralists and lawyers,* are inquiries, perhaps, of more curiosity than use, and which, if they deserve any where to be deeply pursued, will be pursued with more propriety in a full examination of the subject than within the short limits of an introductory discourse. Names are, however, in a great measure arbitrary; but the distribution of knowledge into its parts, though it may often perhaps be varied with little disadvantage, yet

The learned reader is aware that the "jus na

tura" and "jus gentium" of the Roman lawyers are phrases of very different import from the modern phrases, "law of nature" and "law of nations." "Jus naturale," says Ulpian, "est quod natura omnia animalia docuit." D. I. I. I. 3. "Quod naturalis ratio inter omnes homines constituit, id que apud omnes peræque custoditur vocaturque jus gentium." D. I. I. 9. But they sometimes neglect this subtle distinction" Jure naturali quod appellatur jus gentium." I. 2. I. II. Jus feciale was the Roman term for our law of nations. "Belli quidem æquitas sanc

tissimè populi Rom. feciali jure perscripta est." Our learned civilian Zouch has accord
