NASSAU WILLIAM SENIOR (1790-1864), English political economist, was born at Compton, Berks, on 26th September 1790, the eldest son of the Rev. J. B. Senior, vicar of Durnford, Wilts. He was educated at Eton and Magdalen College, Oxford; at the university he was a private pupil of Richard Whately, afterwards archbishop of Dublin, with whom he remained connected by ties of lifelong friendship. He took the degree of B.A. in 1811, was called to the bar in 1819, and in 1836, during the chancellorship of Lord Cottenham, was appointed a master in chancery. On the foundation of the professorship of political economy at Oxford in 1825, Senior was elected to fill the chair, which he occupied till 1830, and again from 1847 to 1852. In 1830 he was requested by Lord Melbourne to inquire into the state of combinations and strikes, to report on the state of the law, and to suggest improvements in it. He was a member of the Poor Law Inquiry Commission of 1832, and of the Handloom Weavers Commission of 1837 ; the report of the latter, published in 1841, was drawn up by him, and he embodied in it the substance of the report he had prepared some years before on combinations and strikes. He was also one of the commissioners appointed in 1861 to inquire into popular education in England. In the later years of his life, during his visits to foreign countries, he studied with much care the political and social phenomena they exhibited. Several volumes of his journals have been pub-lished, which contain much interesting matter on these topics, though the author probably rated too highly the value of this sort of social study. Senior was for many years a frequent contributor to the Edinburgh, Quarterly, London, and North British Reviews, dealing in their pages with literary as well as with economic and political sub-jects. He died at Kensington on 4th June 1864.

His writings on economic theory consisted of an article in the Encyclopaedia Metropolitana, afterwards separately published as An Outline of the Science of Political Economy (1836, 3d ed. 1854), and his lectures delivered at Oxford. Of the latter the following were printed—An Introductory Lecture (1827, 3d ed. 1831); Two Lectures on Population, with a correspondence between the author and Malthus (1831); Three Lectures on the Transmission of the Precious Metals from Country to Country, and the Mercantile Theory of Wealth (1828) ; Three Lectures on the Cost of obtaining Money and on some Effects of Private and Government Paper Money (1830); Three Lectures on Wages and on the Effects of Absenteeism, Machinery, and War, with a Preface on the Causes and Remedies of the Present Disturbances (1830, 2d ed. 1831); A Lecture on the Production of Wealth (1847); and Four Introductory Lectures on Political Economy (1852). Several of his lectures were translated into French by M. Arrivabene under the title of Principes Fondamentaux d'Economie Politique (1835). Senior also wrote on administrative and social questions—A Letter to Lord Howick on a Legal Provision for the Irish Poor, Commutation of Tithes, and a Provision for the Irish Roman Catholic Clergy (1831, 3d ed. 1832, with a preface containing suggestions as to the measures to be adopted in the " present emergency "); Statement of the Provision for the Poor and of the Condition of the Labouring Classes in a considerable portion of America and Europe, being the Preface to the Foreign Communications in the Appendix to the Poor Law Report (1835); On National Properly, and on the Prospects of the Present Administration and of their Successors (anon. ; 1835) ; Letters on the Factory Act, as it affects the Cotton Manufacture (1837); Suggestions on Popular Education (1861); American Slavery (in part a reprint from the Edinburgh Review; 1862) ; An Address on Education delivered to the Social Science Association (1863). His contributions to the reviews were collected in volumes entitled Essays on Fiction (1864); Biographical Sketches (1865, chiefly of noted lawyers); and Historical and Philosophical Essays (1865). In 1859 appeared his Journal kept in Turkey and Greece in the Autumn of 1857 and the Beginning of 1858 ; and the following were edited after his death by his daughter—Journals, Conversations, and Essays relating to Ireland (1868) ; Journals kept in France and Italy from 1848 to 1852, with a Sketch of the Revolution of 1848 (1871); Conversations with Thiers, Guizot, and other Distinguished Persons during the Second Empire (1878) ; Conversations with Distinguished, Persons during the Second Empire, from 1860 to 1863 (1880); Conversations and Journals in Egypt and Malta (1882); also in 1872 Correspondence and Conver-sations with Alexis de Tocqueville from 1884 to 1859.





Senior's literary criticisms do not seem to have ever won the favour of the public ; they are, indeed, somewhat formal and academic in spirit. The author, while he had both good sense and right feeling, appears to have wanted the deeper insight, the geniality, and the catholic tastes which are necessary to make a critic of a high order, especially in the field he chose,—that, namely, of imaginative literature. His tracts on practical politics, though the theses they supported were sometimes questionable, were ably written and are still worth reading, but cannot be said to be of much permanent interest. But his name will continue to hold an honourable, though secondary, place in the history of political economy. Senior regards political economy as a purely deductive science, all the truths of which are inferences from four elementary propositions. It is, in his opinion, wrongly supposed by J. S. Mill and others to be a hypothetic science,—founded, that is to say, on postulates not corresponding with social realities. The premises from which it sets out are, according to him, not assumptions but facts. It concerns itself, however, with wealth only, and can therefore give no practical counsel as to political action : it can only suggest considerations which the politician should keep in view as elements in the study of the questions with which he has to deal. The conception of economics as altogether deductive is certainly erroneous, and puts the science from the outset on a false path. But deduction has a real, though limited, sphere within it. Hence, though the chief difficulties of the subject are not of a logical kind, yet accurate nomenclature, strict definition, and rigorous reasoning are of great importance. To these Senior has given special atten-tion, and, notwithstanding occasional pedantries, with very useful results. He has in several instances improved the forms in which accepted doctrines were habitually stated. He has also done ex-cellent service by pointing out the arbitrary novelties and frequent inconsistencies of terminology which deface Ricardo's principal work,—as, for example, his use of "value" in the sense of "cost of production," and of "high " and "low " wages ill the sense of a certain proportion of the product as distinguished from an absolute amount, and his peculiar employment of the epithets "fixed" anil "circulating" as applied to capital. He shows, too, that in numerous instances the premises assumed by Ricardo arc false. Thus he cites the assertions that rent depends on the difference of fertility of the different portions of land in cultivation ; that the labourer always receives precisely the necessaries, or what custom leads him to consider the necessaries, of life ; that, as wealth and population advance, agricultural labour becomes less and less pro-portionately productive ; and that therefore the share of the pro-duce taken by the landlord and the labourer must constantly in-crease, whilst that taken by the capitalist must constantly diminish; and he denies the truth of all these propositions. Besides adopting some terms, such as that of "natural agents," from Say, Senior introduced the word "abstinence"—which, though obviously not free from objection, is for some purposes useful—to express the conduct of the capitalist which is remunerated by interest; but in defining "cost of production " as the sum of labour and abstinence necessary to production he,does not seem to see that an amount of labour and an amount of abstinence are disparate, and do not admit of reduction to a common quantitative standard. He has added some important considerations to what had been said by Smith on the division of labour. He distinguishes usefully between the rate of wages and the price of labour. But in seeking to deter- mine the law of wages he falls into the error of assuming a deter- minate wage-fund, and states as an economic truth what is only an identical proposition in arithmetic. Whilst entertaining such an exaggerated estimate of the services of Malthus that he extra- vagantly pronounces him "as a benefactor of mankind on a level with Adam Smith," ho yet shows that he modilied his opinions on population considerably in the course of his career, regards his statements of the doctrine with which his name is associated as vague and ambiguous, and asserts that, "in the absence of disturb- ing causes, subsistence may be expected to increase in a greater ratio than population." It is urged by Perin, and must, we think, be admitted, that by his isolation of economics from morals, and his assumption of the desire of wealth as the sole motive-force in the economic domain, Senior has, in common with most of the other followers of Smith, tended to set up egoism as the legitimate ruler and guide of practical life. It is no sufficient answer to this charge that he makes formal reserve in favour of higher ends. From the scientific side, Gliffe Leslie has abundantly proved the unsubstantial nature of the abstraction implied in the phrase "desire of wealth," and the inadequacy of such a principle for the explanation of economic phenomena.
