The period of Mr. Mill’s most intimate connection with “The London and Westminster Review” forms a brilliant episode in the history of journalism; and his relations, then and afterwards, with other men of letters and political writers,—some of them as famous as Mr. Carlyle and Coleridge, Charles Buller and Sir Henry Taylor, Sir William Molesworth, Sir John Bowring, and Mr. Roebuck,—yield tempting materials for even the most superficial biography; but we must pass them by for the present. And here we shall content ourselves with enumerating, in the order of their publication, those lengthier writings with which he chiefly occupied his leisure during the next quarter of a century; though that work was frequently diversified by important contributions to “The Edinburgh” and “The Westminster Review,” “Fraser’s Magazine,” and other periodicals. His first great work was “A System of Logic,” the result of many years’ previous study, which appeared in 1843. That completed, he seems immediately to have paid chief attention to politico-economical questions. In 1844 appeared “Essays on Some Unsettled Questions of Political Economy,” which were followed, in 1848, by the “Principles of Political Economy.” After that there was a pause of ten years, though the works that were issued during the next six years show that he had not been idle during the interval. In 1857 were published two volumes of the “Dissertations and Discussions,” consisting solely of printed articles, the famous essay “On Liberty,” and the “Thoughts on Parliamentary Reform.” “Considerations on Representative Government” appeared in 1861, “Utilitarianism,” in 1863, “Auguste Comte and Positivism” and the “Examination of Sir William Hamilton’s Philosophy,” in 1865. After that, besides the very welcome “Inaugural Address” at St. Andrew’s in 1867, his only work of importance was “The Subjection of Women,” published in 1869. A fitting conclusion to his more serious literary labors appeared also in 1869 in his annotated edition of his father’s “Analysis of the Phenomena of the Human Mind.”
