There are other circumstances to which I allude with hesitation and reluctance, though it must be owned that they afford to a writer of this age some degree of unfortunate and deplorable advantage over his predecessors. Recent events have accumulated more terrible practical instruction on every subject of politics than could have been in other times acquired by the experience of ages. Men's wit, sharpened by their passions, has penetrated to the bottom of almost all political questions. Even the fundamental rules of morality themselves have, for the first time, unfortunately for mankind, become the subject of doubt and discussion. I shall consider it as my duty to abstain from all mention of these awful events, and of these fatal controversies. But the mind of that man must indeed be incurious and indocile, who has either overlooked all these things; or reaped no instruction from the contemplation of them. From these reflections it appears, that, since the composition of those two great works on the Law of Nature and Nations which continue to be the classical and standard works on that subject, we have gained both more convenient instruments of reasoning and more extensive materials for science; that the code of war has been enlarged and improved; that new questions have been practically decided; and that new controversies have arisen regarding the intercourse of independent states, and the first principles of morality and civil government. Some readers may, however, think that in these observations which I offer, to excuse the presumption of my own attempt, I have omitted the mention of later writers, to whom some part of the remarks is not justly applicable. But, perhaps, further consideration will acquit me in the judgment of such readers. Writers on particular questions of public law are not within the scope of my observations. They have furnished the most valuable materials; but I speak only of a system. To the large work of Wolffius, the observations which I have made on Puffendorff as a book for general use, will surely apply with tenfold force. His abridger, Vattel, deserves, indeed, considerable praise. He is a very ingenious, clear, elegant, and useful writer. But he only considers one part of this extensive subject, namely, the law of nations strictly so called; and I cannot help thinking, that, even in this department of the science, he has adopted some doubtful and dangerous principles, not to mention his constant deficiency in that fulness of example and illustration, which so much embellishes and strengthens reason. It is hardly necessary to take any notice of the text-book of Heineccius, the best writer of elementary books with whom I am acquainted on any subject. Burlamaqui is an author of superior merit; but he confines himself too much to the general principles of morality and politics, to require much observation from me in this place. The same reason will
