REVIEW OF THE WORK OF MR JOHN STUART MILL

ENTITLED, 'EXAMINATION OF SIR WILLIAM HAMILTONS PHILOSOPHY'

BY GEORGE GROTE

An Examination of Sir William Hamilton's Philosophy, and of the Principal Philosophical Questions discussed in his Writings. By JOHN STUART MILL. London: Longmans. 1865.

The work bearing the above title is an octavo volume, consisting of twenty-eight chapters, and five hundred and sixty pages. This is no great amount of print; but the amount of matter contained in it is prodigious, and the quality of that matter such as to require a full stretch of attention. Mr Mill gives his readers no superfluous sentences, scarcely even a superfluous word, above what is necessary to express his meaning briefly and clearly. Of such a book no complete abstract can be given in the space to which we are confined.

To students of philosophy—doubtless but a minority among the general circle of English readers—this work comes recommended by the strongest claims both of interest and instruction. It presents in direct antithesis two most conspicuous representatives of the modern speculative mind of England—Sir W. Hamilton and Mr John Stuart Mill.

Sir W. Hamilton has exercised powerful influence over the stream of thought during the present generation. The lectures on Logic and Metaphysics delivered by him at Edinburgh, for twenty years, determined the view taken of those subjects by a large number of aspiring young students, and determined that view for many of them permanently and irrevocably.^[1] Several eminent teachers and writers of the present day are proud of considering themselves his disciples, enunciate his doctrines in greater or less proportion, and seldom contradict him without letting it be seen that they depart unwillingly from such a leader. Various new phrases and psychological illustrations have obtained footing in treatises of philosophy, chiefly from his authority. We do not number ourselves among his followers; but we think his influence on philosophy was in many ways beneficial. He kept up the idea of philosophy as a subject to be studied from its own points of view: a dignity which in earlier times it enjoyed, perhaps, to mischievous excess, but from which in recent times it has far too much receded—especially in England. He performed the great service of labouring strenuously to piece together the past traditions of philosophy, to re-discover those which had been allowed to drop into oblivion, and to make out the genealogy of opinions as far as negligent predecessors had still left the possibility of doing so.

The forty-six lectures on Metaphysics, and the thirty-five lectures on Logic, published by Messrs Mansel and Veitch, constitute the biennial course actually delivered by Sir W. Hamilton in the Professorial Chair. They ought therefore to be looked at chiefly with reference to the minds of youthful hearers, as preservatives against that mischief forcibly described by Rousseau—'L'inhabitude de penser dans la jeunesse en ôte la capacité pendant le reste de la vie.'

Now, in a subject so abstract, obscure, and generally unpalatable, as Logic and Metaphysics, the difficulty which the teacher finds in inspiring interest is extreme. That Sir W. Hamilton overcame such difficulty with remarkable success, is the affirmation of his two editors; and our impression, as readers of his lectures, disposes us to credit them. That Sir W. Hamilton should have done this effectively is in itself sufficient to stamp him as a meritorious professor—as a worthy successor to the chair of Dugald Stewart, whose unrivalled perfection in that department is attested by every one. Many a man who ultimately adopted speculative opinions opposed to Dugald Stewart, received his first impulse and guidance in the path of speculation from the lasting impression made by Stewart's lectures.

But though we look at these lectures, as they ought to be looked at, chiefly with a view to the special purpose for which they were destined, we are far from insinuating that they have no other merits, or that they are useless for readers who have already a metaphysical creed of their own. We have found them both instructive and interesting: they go over a large proportion of the field of speculative philosophy, partly from the point of view (not always the same) belonging to the author, partly from that of numerous predecessors whom he cites. We recognize also in Sir W. Hamilton an amount of intellectual independence which seldom accompanies such vast erudition. He recites many different opinions, but he judges them all for himself; and, what is of still greater moment, he constantly gives the reasons for his judgments. To us these reasons are always of more or less value, whether we admit them to be valid or not. Many philosophers present their own doctrine as if it were so much ascertained and acknowledged truth, either intimating, or leading you to suppose, that though erroneous beliefs to the contrary formerly prevailed, these have now become discredited with every one. We do not censure this way of proceeding, but we prefer the manner of Sir W. Hamilton. He always keeps before us divergence and discrepancy of view as the normal condition of reasoned truth or philosophy; the characteristic postulate of which is, that every affirmative and every negative shall have its appropriate reasons clearly and fully enunciated.

In this point of view the appendix annexed to the lectures is also valuable; and the four copious appendixes or dissertations following the edition of Reid's works, are more valuable still. How far Sir W. Hamilton has there furnished good proof of his own doctrines on External Perception, and on the Primary Qualities of Matter, we shall not now determine; but to those who dissent from him, as well as to those who agree with him, his reasonings on these subjects are highly instructive: while the full citations from so many other writers contribute materially not only to elucidate the points directly approached, but also to enlarge our knowledge of philosophy generally. We set particular value upon this preservation of the traditions of philosophy, and upon this maintenance of a known perpetual succession among the speculative minds of humanity, with proper comparisons and contrasts. We have found among the names quoted by Sir W. Hamilton, and, thanks to his care, several authors hardly at all known to us, and opinions cited from them not less instructive than curious. He deserves the more gratitude, because he departs herein from received usage since Bacon and Descartes. The example set by these great men was admirable, so far as it went to throw off the authority of predecessors; but pernicious so far as it banished those predecessors out of knowledge, like mere magazines of immaturity and error. Throughout the eighteenth century, all study of the earlier modes of philosophizing was, for the most part, neglected. Of such neglect, remarkable instances are pointed out by Sir W. Hamilton.

While speaking about the general merits and philosophical position of Sir William Hamilton, we have hitherto said nothing about those of Mr Mill. But before we proceed to analyze the separate chapters of his volume, we must devote a few words to the fulfilment of another obligation.

Mr John Stuart Mill has not been the first to bestow honour on the surname which he bears. His father, Mr James Mill, had already ennobled the name. An ampler title to distinction in history and
