But though I follow substantially the example of Turgot and Ricardo, I do not propose to follow it implicitly. Though I profess to teach only the theory of wealth, I do not refuse the right to consider its practical application. There is, indeed, something imposing and almost seductive in a work of pure science, especially if it be a science connected with human affairs. We admire the impartiality of the philosopher who discusses matters that agitate nations without mixing in the strife, or noticing the use that may be made of the truths which he scatters. And we admit, with comparative readiness, conclusions which do not appear to have been influenced by passion, the great disturber of observation and of reasoning. This was one of the great causes of the popularity of Ricardo. He was the first English writer who produced Political Economy in a purely scientific form. He is usually a logical reasoner, so that his conclusions can seldom be denied if his premises are conceded, and his premises must usually be conceded, for they are usually hypothetical. Men were delighted to find what appeared to be firm footing, in a new and apparently unstable science, and readily gave their assent to theories which did not obviously lead to practice. But though it be desirable that from time to time a writer should arise able and willing to treat the science in this severe and abstract manner, his treatise will be more serviceable to masters than to students. To those who are already familiar with the subject, to those who have already perceived how deeply mankind

are interested in obtaining correct views as to the laws which regulate the production and distribution of wealth, a naked statement of those laws, though it should not possess the elegance of Turgot, or the originality of Ricardo, must still be useful, and even agreeable. A mere student would find it repulsive. He ought to be attracted to Political Economy by seeing from time to time its practical application. He should be taught that he is studying a science composed of principles which no statesman, no legislator, no magistrate, no member even of a board of guardians can safely disregard. And this will be best effected by putting before him examples of the good which has been done by adhering to those principles, and of the evil which has punished their neglect. These examples, therefore, I shall think myself at liberty to give. I shall think myself justified, for instance, in showing how the natural distribution of wealth may be affected by the institution of poorlaws. And I shall not confine myself to their effects upon wealth. I shall consider how far a well-framed poor-law may promote the moral as well as the material welfare of the labouring classes, and an illadministered poor-law may produce moral, intellectual, and physical degradation. But these discussions must be considered as episodes. They form no part I shall enter into

of the science which I profess. them, not as a political economist, but as a statesman or a moralist; and I shall expect from those who do me the honour of listening to them, not the full conviction which follows scientific reasoning, but the

qualified assent which is given to the precepts of an

art.

In the next Lecture I shall consider whether the science of Political Economy may be more conveniently based on positive or on hypothetical principles.

LECTURE IV.

THAT POLITICAL ECONOMY IS A POSITIVE, NOT AN HYPOTHETICAL SCIENCE.-DEFINITION OF WEALTH.

IN the present Lecture I shall consider whether the science of Political Economy may be more conveniently based on positive or on hypothetical principles, and shall afterwards explain, more fully than I have as yet done, the sense in which I use the word wealth. Mr. John Mill, who has contributed much to Political Economy, as he has, indeed, to every science which he has touched, maintains that it is based on hypothesis. As it is impossible to change Mr. Mill's language for the better, I shall extract the material parts of the passage in which he states and supports this opinion.

"Political Economy," he says, "is concerned with man solely as a being who desires to possess wealth, and who is capable of judging of the comparative efficacy of means for obtaining that end. It predicts only such of the phenomena of the social state as take place in consequence of the pursuit of wealth. It

makes entire abstraction of every other human passion or motive, except those which may be regarded as perpetually antagonising principles to the desire of wealth; namely, aversion to labour, and desire of the present enjoyment of costly indulgences. These it takes, to a certain extent, into its calculations, because these do not merely, like other desires, occasionally conflict with the pursuit of wealth, but accompany it always as a drag or impediment, and are therefore inseparably mixed up in the consideration of it. Political Economy considers mankind as occupied solely in acquiring and consuming wealth, and aims at showing what is the course of action into which mankind, living in a state of society, would be impelled, if that motive, except in the degree in which it is checked by the two perpetual counter-motives above adverted to, were absolutely ruler of all their actions. Under the influence of this desire, it shows mankind accumulating wealth, and employing wealth in the production of other wealth; sanctioning by mutual agreement the institution of property; establishing laws to prevent individuals from encroaching upon the property of others by force or fraud; adopting various contrivances for increasing the productiveness of their labour; settling the division of the produce by agreement, under the influence of competition (competition itself being governed by certain laws, which laws are therefore the ultimate regulators of the division of the produce), and employing certain expedients, as money, credit, &c., to facilitate the distribution. All these operations, though many of
