Several authors, in this country, had before written on commercial affairs, but Mr. Smith was the first who reduced to a regular form and order the information that was to be obtained on that subject, and deduced from it the policy which an enlightened commercial nation ought to adopt. The successful manner in which he has treated this unlimited freedom of trade, as well as some others, and his able exposure of the errors of the commercial system, have rendered the science of which he treats highly interesting to the great body of the people; and a spirit of inquiry, on every branch of political economy, has, in consequence, been excited, which promises now, more than ever, to be attended with the most beneficial effects. This intricate science, the most important to the interests of mankind though long neglected, Dr. Smith has had the merit of advancing so far, as to lay a foundation, on which, it may safely be said, investigation may for a long time proceed. It has frequently been alleged, that Dr. Smith was indebted for a large portion of the reasonings in his Inquiry to the French economists, and that the coincidence between some branches of his doctrine and theirs, particularly those which relate to freedom of trade and the powers of labour, is more than casual. But Professor Stewart has ably vindicated him from this charge, and established his right to the general principles of his doctrine, which, he thinks, were altogether original, and the result of his own reflections. That he, however, derived some advantage from his intimacy with Turgot, and those great men who were at the head of the sect of economists, and, perhaps, adopted some of their illustrations, it would be as unnecessary to deny, as it would he far from discreditable to his talents to acknowledge.
