prodigious increase of wealth in those nations which are most loaded with indirect taxes, deserve to be discussed at greater length than our limits will allow. Enough, however, has been said to shew, that no rigorous and purely mathematical calculation will ever enable us to appreciate the real influence of taxes upon the prosperity of a nation. Thus, some of the truths perceived by the economists are of little use in practice; while others are found to be contradicted in their application, by those accessory circumstances which were overlooked in the calculations of the theory. While this sect of philosophers filled all Europe with their speculations, an observer of more depth and ability directed his researches to the same subject, and laboured to establish, on a true and lasting foundation, the doctrines of political economy. Dr. Smith succeeded in discovering a great truth,--the most fruitful in consequences, the most useful in practice, the origin of all the principles of the science, and one which unveiled to him all the mysteries of the growth and distribution of wealth. This great man perceived, that the universal agent in the creation of wealth is labour; and was thence led to analyse the powers of this agent, and to search after the causes to which they owe their origin and increase. The great difference between the doctrine of Smith and of the economists, lies in the point from which they set out, in the reduction of their consequences. The latter go back to the soil as the primary source of all wealth; while the former regards labour as the universal agent which, in every case, produces it. It will appear, at first sight, how very superior the school of the Scotch professor is to that of the French philosophers, with regard to the practical utility, as well as to the application of its precepts. Labour is a power of which man is the machine; and, of course, the increase of this power can only be limited by the indefinite bounds of human intelligence and industry; and it possesses, like these faculties, a susceptibility of being directed by design, and perfected by the aid of study. The earth, on the contrary, if we set aside the influence which labour has over the nature and quantity of its productions, is totally out of our power, in every respect which can render it more or less useful--in its extent, in its situation, and in its physical properties. Thus the science of political economy, considered according to the view of the French economists, must be classed with the natural sciences, which are purely speculative, and can have no other end than the knowledge of the laws which regulate the object of their researches; while, viewed according to the doctrine of Smith, political economy becomes connected with the other moral sciences, which tend to ameliorate the condition of their object, and to carry it to the highest perfection of which it is susceptible.
