learning, he has yet treated this subject with sound sense, with clear method, with extensive and accurate knowledge, and with a copiousness of detail sometimes indeed tedious, but always instructive and satisfactory. His work will be always studied by those who spare no labour to acquire a deep knowledge of the subject; but it will, in our times, I fear, be oftener found on the shelf than on the desk of the general student. In the time of Mr. Locke it was considered as the manual of those who were intended for active life; but in the present age I believe it will be found that men of business are too much occupied, men of letters are too fastidious, and men of the world too indolent, for the study or even the perusal of such works. Far be it from me to derogate from the real and great merit of so useful a writer as Puffendorff. His treatise is a mine in which all his successors must dig. I only presume to suggest, that a book so prolix, and so utterly void of all the attractions of composition, is likely to repel many readers who are interested, and who might perhaps be disposed to acquire

some knowledge of the principles of public law.

Many other circumstances might be mentioned, which conspire to prove that neither of the great works of which I have spoken, has superseded the necessity of a new attempt to lay before the public a System of the Law of Nations. The language of science is so completely changed since both these works were written, that whoever was now to employ their terms in his moral reasonings would be almost unintelligible to some of his hearers or readers; and to some among them too who are neither ill qualified nor ill disposed to study such subjects with considerable advantage to themselves. The learned indeed well know how little novelty or variety is to be found in scientific disputes. The same truths and the same errors have been repeated from age to age, with little variation but in the language; and novelty of expression is often mistaken by the ignorant for substantial discovery. Perhaps too very nearly the same portion of genius and judgment has been exerted in most of the various forms under which science

has been cultivated at different periods of history. The superiority of those writers who continue to be read, perhaps often consists chiefly in taste, in prudence, in a happy choice of subject, in a favourable moment, in an agreeable style, in the good fortune of a prevalent language, or in other advantages which are either accidental, or are the result rather of the secondary than of the highest faculties of the mind.-But these reflections, while they moderate the pride of invention, and dispel the extravagant conceit of superior illumination, yet serve to prove the use, and indeed the necessity, of composing, from time to time, new systems of science adapted to the opinions and language of each succeeding period. Every age must be taught in its own. language. If a man were now to begin a discourse on ethics with an account of the "moral entities" of Puffendorff,* he would speak an unknown tongue.

*I do not mean to impeach the soundness of any part of Puffendorff's reasoning founded on moral entities. It may be explained in a manner consistent

It is not, however, alone as a mere translation of former writers into modern language that a new system of public law seems likely to be useful. The age in which we live possesses many advantages which are peculiarly favourable to such an undertaking. Since the composition of the great works of Grotius and Puffendorff, a more modest, simple, and intelligible philosophy has been introduced into the schools; which has indeed been grossly abused by sophists, but which, from the time of Locke, has been cultivated and improved by a succession of disciples worthy of their illustrious master. We are thus enabled to discuss with precision, and to explain with clearness, the principles of the science of human nature, which are in themselves on a level with the capacity of every man of good sense, and which only appeared to be abstruse

with the most just philosophy. He used, as every writer must do, the scientific language of his own time. I only assert that, to those who are unacquainted with ancient systems, his philosophical vocabulary is obsolete and unintelligible.

from the unprofitable subtleties with which they were loaded, and the barbarous jargon in which they were expressed. The deepest doctrines of morality have since that time been treated in the perspicuous and popular style, and with some degree of the beauty and eloquence of the ancient moralists. That philosophy on which are founded the principles of our duty, if it has not become more certain (for morality admits no discoveries), is at least less "harsh and crabbed," less obscure and haughty in its language, less forbidding and disgusting in its appearance, than in the days of our ancestors. If this progress of learning towards popularity has engendered (as it must be owned that it has) a multitude of superficial and most mischievous sciolists, the antidote must come from the same quarter with the disease. Popular reason can alone correct popular sophistry.

Nor is this the only advantage which a writer of the present age would possess over the celebrated jurists of the last century. Since that time vast additions have been
