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 philosophy can seldom be produced than that which Mr James Mill left behind him. We know no work which surpasses his 'History of British India' in the main excellencies attainable by historical writers: industrious accumulation, continued for many years, of original authorities—careful and conscientious criticism of their statements—and a large command of psychological analysis, enabling the author to interpret phenomena of society, both extremely complicated, and far removed from his own personal experience. Again, Mr James Mill's 'Elements of Political Economy' were, at the time when they appeared, the most logical and condensed exposition of the entire science then existing. Lastly, his latest avowed production, the 'Analysis of the Phenomena of the Human Mind,' is a model of perspicuous exposition of complex states of consciousness, carried farther than by any other author before him; and illustrating the fulness which such exposition may be made to attain, by one who has faith in the comprehensive principle of association, and has learnt the secret of tracing out its innumerable windings. It is, moreover, the first work in which the great fact of Indissoluble Association is brought into its due theoretical prominence. These are high merits, of which lasting evidence is before the public; but there were other merits in Mr James Mill, less publicly authenticated, yet not less real. His unpremeditated oral exposition was hardly less effective than his prepared work with the pen; his colloquial fertility on philosophical subjects, his power of discussing himself, and of stimulating others to discuss, his ready responsive inspirations through all the shifts and windings of a sort of Platonic dialogue—all these accomplishments were, to those who knew him, even more impressive than what he composed for the press. Conversation with him was not merely instructive, but provocative to the dormant intelligence. Of all persons whom we have known, Mr James Mill was one who stood least remote from the lofty Platonic ideal of Dialectic—[Greek: Tou didhonai kahi dhechesthai lhogon ]—(the giving and receiving of reasons) competent alike to examine others, or to be examined by them, on philosophy. When to this we add a strenuous character, earnest convictions, and single-minded devotion to truth, with an utter disdain of mere paradox—it may be conceived that such a man exercised powerful intellectual ascendancy over younger minds. Several of those who enjoyed his society—men now at, or past, the maturity of life, and some of them in distinguished positions—remember and attest with gratitude such ascendancy in their own cases: among them the writer of the present article, who owes to the historian of British India an amount of intellectual stimulus and guidance such as he can never forget.

When a father, such as we have described, declining to send his son either to school or college, constituted himself schoolmaster from the beginning, and performed that duty with laborious solicitude—when, besides full infusion of modern knowledge, the forcing process applied by the Platonic Socrates to the youth-Theætêtus, was administered by Mr James Mill, continuously and from an earlier age, to a youthful mind not less pregnant than that of Theætêtus—it would be surprising if the son thus trained had not reached even a higher eminence than his father. The fruit borne by Mr John Stuart Mill has been worthy of the culture bestowed, and the volume before us is at once his latest and his ripest product.

The 'Examination of Sir William Hamilton's Philosophy' is intended by Mr Mill (so he tells us in the preface to the sixth published edition of his 'System of Logic, Ratiocinative and Inductive') as a sequel and complement to that system. We are happy to welcome so valuable an addition; but with or without that addition, the 'System of Logic' appears to us to present the most important advance in speculative theory which the present century has witnessed. Either half of it, the Ratiocinative or the Inductive, would have surpassed any previous work on the same subject. The Inductive half discriminates and brings into clear view, for the first time, those virtues of method which have insensibly grown into habits among consummate scientific inquirers of the post-Baconian age, as well as the fallacies by which some of these authors have been misled. The Ratiocinative half, dealing with matters which had already been well handled by Dutrieu and other scholastic logicians, invests their dead though precise formalism with a real life and application to the actual process of finding and proving truth. But besides thus working each half up to perfection, Mr Mill has performed the still more difficult task of overcoming the repugnance, apparently an inveterate repugnance, between them, so as chemically to combine the two into one homogeneous compound; thus presenting the problem of Reasoned Truth, Inference, Proof, and Disproof, as one connected whole. For ourselves, we still recollect the mist which was cleared from our minds when we first read the 'System of Logic,' very soon after it was published. We were familiar with the Syllogistic Logic in Burgersdicius and Dutrieu; we were also familiar with examples of the best procedure in modern inductive science; but the two streams flowed altogether apart in our minds, like two parallel lines never joining nor approaching. The irreconcilability of the two was at once removed, when we had read and mastered the second and third chapters of the Second Book of the 'System of Logic;' in which Mr Mill explains the functions and value of the Syllogism, and the real import of its major premiss. This explanation struck us at the time as one of the most profound and original efforts of metaphysical thought that we had ever perused, and we see no reason to retract that opinion now. ^[2] It appears all the more valuable when we contrast it with what is said by Mr Mill's two contemporaries—Hamilton and Whately: the first of whom retains the ancient theory of reasoning, as being only a methodized transition from a whole to its parts, and from the parts up to the whole—Induction being only this ascending part of the process, whereby, after having given a complete enumeration of all the compound parts, you conclude to the sum total described in one word as a whole; ^[3] while the second (Whately) agrees in subordinating Induction to Syllogism, but does so in a different way—by representing inductive reasoning as a syllogism, with its major premiss suppressed, from which major premiss it derived its authority. The explanation of Mr Mill attacks the problem from the opposite side. It subordinates syllogism to induction, the technical to the real; it divests the major premiss of its illusory pretence to be itself the proving authority, or even any real and essential part of the proof—and acknowledges it merely as a valuable precautionary test and security for avoiding mistake in the process of proving. Taking Mr Mill's 'System of Logic' as a whole, it is one of the books by which we believe ourselves to have most profited. The principles of it are constantly present to our mind when engaged in investigations of evidence, whether scientific or historical.

Concerned as we are here with Mr Mill only as a logician and philosopher, we feel precluded from adverting to his works on other topics—even to his 'Elements of Political Economy,' by which he is probably more widely known than by anything else. Of the many obligations which Political Economy owes to him, one only can be noticed consistent with the scope of the present article: the care which he has taken—he alone, or at least, he more explicitly and formally than any other expositor—to set forth the general position of that science in the aggregate field of scientific research; its relation to sociology as a whole, or to other fractions thereof, how far derivative or co-ordinate; what are its fundamental postulates or hypotheses, with what limits the logical methods of induction and deduction are applicable to it, and how far its conclusions may be relied on as approximations to truth. All these points will be found instructively handled in the Sixth Book of Mr Mill's 'System of Logic,' as well as in his smaller and less known work, 'Essays on Some Unsettled Questions in Political Economy.' We find him, while methodizing and illustrating the data of the special science, uniformly keeping in view its relation to philosophy as a whole.

But there is yet another work in which the interests of philosophy, as a whole, come into the foreground and become the special object of vindication in their largest compass and most vital requirements. We mean Mr Mill's 'Essay on Liberty,' one half of which takes for its thesis the libertus philosophandi . He maintains, emphatically, in this book, the full dignity of reasoned truth against all the jealous exigencies of traditional dogma and self-justifying sentiment. He claims the most unreserved liberty of utterance for negative and affirmative on all questions—not merely for the purpose of discriminating truth from falsehood, but also to keep up in individual minds the full sense and understanding of the matters controverted, in place of a mere partial and one-sided adhesion. At first sight, indeed, it might seem as if Mr Mill was fighting with a shadow; for liberty of philosophizing is a postulate which, in general terms, every one concedes. But when you come to fathom the real feelings which underlie this concession, you discover that almost every man makes it under reserves which, though acting in silence, are not the less efficacious. Every one has some dogmas which he cannot bear to hear advocated, and others which he will not allow to be controverted in his presence. A writer has to consider not merely by what reasons any novelty of belief or disbelief may be justified, but also how much it will be safe for him to publish, having regard to the irritable sore places of the public judgment. In July, 1864, we were present at the annual meeting of the French Academy at Paris, where the prizes for essays sent in, pursuant to subjects announced for study beforehand, are awarded. We heard the titles of various compositions announced by the President (M. Villemain), with a brief critical estimate of each. Their comparative merits were appreciated, and the prize awarded to one of the competitors. Among the compositions sent to compete for the prize, one was a work by M. Taine, upon which the President bestowed the most remarkable encomiums, in every different point of view: extent of knowledge, force of thought, style, arrangement, all were praised in a manner which we have rarely heard exceeded. Nevertheless, the prize was not awarded to this work, but to another which the President praised in a manner decidedly less marked and emphatic. What was here the ratio decidendi ? The reason was, and the President declared it in the most explicit language, that the work of M. Taine was deeply tainted with materialism . 'Sans doute,' said the esteemed veteran of French literature in pronouncing his award, 'sans doute les opinions sont libres, mais '—It is precisely against this mais —ushering in the special anathematized or consecrated conclusion which it is intended to except from the general liberty of enforcing or impugning—in matters of philosophical discussion, that Mr Mill, in the 'Essay on Liberty,' declares war as champion of Reasoned Truth.

He handles this grand theme— eleythheroys eleythherôs philosophein —involving as it does the best interests of philosophy, as an instructress to men's judgments, and a stimulus to their intelligence—with great depth of psychological analysis sustained by abundant historical illustration. And he in the same volume discusses most profitably another question akin to it—To what extent, and by what principles, the interference of others is justifiable, in restraining the liberty of taste and action for each individual? A question at once grave and neglected, but the discussion of which does not belong to our present article.

A new work from one who has already manifested such mastery of philosophy, both in principle and in detail, and a work exhibiting the analysis and appreciation of the philosophical views of an eminent contemporary, must raise the highest expectation. We think no reader will be disappointed who peruses Mr Mill's 'Examination,' and we shall now endeavour to give some account of the manner in which he performs it. Upon topics so abstract and subtle as the contents of this volume, the antithesis between two rival theories is the best way, and often the only way, for bringing truth into clear view; and the 'Examination' here before us is professedly controversy. But of controversy in its objectionable sense—of captious or acrimonious personality—not a trace will here be found. A dignified, judicial equanimity of tone is preserved from first to last. Moreover, though the title and direct purpose of the volume is negative and critical, yet the destructive criticism is pervaded by many copious veins of constructive exposition, embodying Mr Mill's own views upon some of the most intricate problems of metaphysics.

Mr Mill begins his work by analyzing and explaining the doctrine called the Relativity of Human Knowledge:

Mr Mill then proceeds to distinguish these various meanings, and to determine in which of them the phrase is understood by Sir W. Hamilton.

One meaning is, that we only know anything by knowing it as distinguished from something else—that all consciousness is of difference. It is not, however, in this sense that the expression is ordinarily or intentionally used by Sir W. Hamilton, though he fully recognizes the truth which, when thus used, it serves to express. In general, when he says that all our knowledge is relative, the relation he has in view is not between the thing known and other objects compared with it, but between the thing known and the mind knowing—(p. 6).

The doctrine in this last meaning is held by different philosophers in two different forms. Some (e.g. Berkeley, Hume, Ferrier, &c.), usually called Idealists, maintain not merely that all we can possibly know of anything is the manner in which it affects the human faculties, but that there is nothing else to be known; that affections of human or of other minds are all that we can know to exist—that the difference between the ego and the non-ego is only a formal distinction between two aspects of the same reality. Other philosophers (Brown, Mr Herbert Spencer, Auguste Comte, with many others) believe that the ego and the non-ego denote two realities, each self-existent, and neither dependent on the other; that the Noumenon, or 'thing per se ,' is in itself a different thing from the Phenomenon, and equally or more real, but that, though we know its existence, we have no means of knowing what it is. All that we can know is, relatively to ourselves, the modes in which it affects us, or the phenomena which it produces—(pp. 9—11).

The doctrine of Relativity, as held by Kant and his many followers, is next distinguished from the same doctrine as held by Hartley, James Mill, Professor Bain, &c., compatible with either acceptance or rejection of the Berkeleian theory. Kant maintains that the attributes which we ascribe to outward things, or which are inseparable from them in thought, contain additional elements over and above sensations plus an unknowable cause—additional elements added by the mind itself, and therefore still only relative, but constituting the original furniture of the mind itself—inherent laws, partly of our sensitive, partly of our intellectual faculty. It is on this latter point that Hartley and those going along with him diverge. Admitting the same additional elements, these philosophers do not ascribe to the mind any innate forms to account for them, but hold that place, extension, substance, cause, and the rest, &c., are conceptions put together out of ideas of sensation, by the known laws of Association—(pp. 12—14).

Partial Relativity is the opinion professed by most philosophers (and by most persons who do not philosophize). They hold that we know things partly as they are in themselves, partly as they are merely in relation to us.

This discrimination of the various schools of philosophers is highly instructive, and is given with the full perspicuity belonging to Mr Mill's style. He proceeds to examine in what sense Sir W. Hamilton maintained the Relativity of Human Knowledge. He cites passages both from the 'Discussions on Philosophy' and from the Lectures, in which that doctrine is both affirmed in its greatest amplitude, and enunciated in the most emphatic language—(pp. 17, 18, 22, 23). But he also produces extracts from the most elaborate of Sir W. Hamilton's 'Dissertations on Reid,' in which a doctrine quite different and inconsistent is proclaimed—that our knowledge is only partially, not wholly, relative; that the secondary qualities of matter, indeed, are known to us only relatively, but that the primary qualities are known to us as they are in themselves, or as they exist objectively, and that they may be even evolved by demonstration à priori —(pp. 19-26, 30). The inconsistency between the two doctrines, professed at different times, and in different works, by Sir W. Hamilton, is certainly manifest. Mr Mill is of opinion that one of the two must be taken 'in a non-natural sense,' and that Sir W. Hamilton either did not hold, or had ceased to hold, the doctrine of the full relativity of knowledge (pp. 20-28)—the hypothesis of a flat contradiction being in his view inadmissible. But we think it at least equally possible that Sir W. Hamilton held both the two opinions in their natural sense, and enforced both of them at different times by argument; his attention never having been called to the contradiction between them. That such forgetfulness was quite possible, will appear clearly in many parts of the present article. His argument in support of both is equally characterized by that peculiar energy of style which is frequent with him, and which no way resembles the qualifying refinements of one struggling to keep clear of a perceived contradiction.

From hence Mr Mill (chap. iv.) proceeds to criticise at considerable length what he justly denominates the celebrated and striking review of Cousin's philosophy, which forms the first paper in Sir W. Hamilton's 'Discussions on Philosophy.' According to Mr Mill—

Upon this we must remark, that though the 'logical maxim' here laid down by Mr Mill may be generally sound, we think the application of it inconvenient in the present case. Discussions on points of philosophy are best conducted without either invoking or offending religious feeling. M. Cousin maintains that we have a direct intuition of the Infinite and the Absolute: Sir W. Hamilton denies that we have. Upon this point Mr Mill sides entirely with Sir W. Hamilton, and considers 'that the latter has rendered good service to philosophy by refuting M. Cousin,' though much of the reasoning employed in such refutation seems to Mr Mill unsound. But Sir W. Hamilton goes further, and affirms that we have no faculties capable of apprehending the Infinite and the Absolute—that both of them are inconceivable to us, and by consequence unknowable. Herein Mr Mill is opposed to him, and controverts his doctrine in an elaborate argument.

Of this argument, able and ingenious, like all those in the present volume, our limits only enable us to give a brief appreciation. In so far as Mr Mill controverts Sir W. Hamilton, we think him perfectly successful, though there are some points in his reasoning in which we do not fully concur.

In our opinion, as in his, the Absolute alone (in its sense as opposed to relative) can be necessarily unknowable, inconceivable, incogitable. Nothing which falls under the condition of relativity can be declared to be so. The structure of our minds renders us capable of knowing everything which is relative, though there are many such things which we have no evidence, nor shall ever get evidence, to enable us to know. Now the Infinite falls within the conditions of relativity, as indeed Sir W. Hamilton himself admits, when he intimates (p. 58) that though it cannot be known, it is, must be, and ought to be, believed by us, according to the marked distinction which he draws between belief and knowledge. We agree with Mr Mill in the opinion that it is thinkable, conceivable, knowable. Doubtless we do not conceive it adequately, but we conceive it sufficiently to discuss and reason upon it intelligibly to ourselves and others. That we conceive the Infinite inadequately, is not to be held as proof that we do not conceive it at all; for in regard to finite things also, we conceive the greater number of them only inadequately.

We cannot construe to the imagination a polygon with an infinite number of sides (i.e. with a number of sides greater than any given number), but neither can we construe to the imagination a polygon with a million of sides; nevertheless, we understand what is meant by the first description as well as by the second, and can reason upon both. There is, indeed, this difference between the two: That the terms used in describing the first, proclaim at once in their direct meaning that we should in vain attempt to construe it to the imagination; whereas the terms used in describing the second do not intimate that fact. We know the fact only by trial, or by an estimate of our own mental force which is the result of many past trials. If the difference here noted were all which Sir W. Hamilton has in view when he declares the Infinite to be unknowable and incogitable, we should accede to his opinion; but we apprehend that he means much more, and he certainly requires more to justify the marked antithesis in which he places himself against M. Cousin and Hegel. Indeed, the facility with which he declares matters to be incogitable, which these two and other philosophers not only cogitate but maintain as truth, is to us truly surprising. The only question which appears to us important is, whether we can understand and reason upon the meaning of the terms and propositions addressed to us. If we can, the subjects propounded must be cogitable and conceivable, whether we admit the propositions affirmed concerning them or not; if we cannot, then these subjects are indeed incogitable by ourselves in the present state of our knowledge, but they may not be so to our opponent who employs the terms.

In criticising the arguments of Sir W. Hamilton against M. Cousin, Mr Mill insists much on a distinction between (1) the Infinite, and (2) the Infinite in any one or more positive attributes, such as infinite wisdom, goodness, redness, hardness, &c. ^[4] He thinks that Sir W. Hamilton has made out his case against the first, but not against the last; that the first is really 'an unmeaning and senseless abstraction,' a fasciculus of negations, unknowable and inconceivable, but not the last. We think that Mr Mill makes more of this distinction than the case warrants; that the first is not unmeaning, but an intelligible abstraction, only a higher reach of abstraction than the last; that it is knowable inadequately, in the same way as the last—though more inadequately, because of its higher abstraction.

As the finite is intelligible, so also is its negation—the Infinite: we do not say (with M. Cousin) that the two are conjointly given in consciousness—but the two are understood and partially apprehended by the mind conjointly and in contrast. Though the Infinite is doubtless negative as to a degree, it is not wholly or exclusively negative, since it includes a necessary reference to some positive attribute, to which the degree belongs; the positive element is not eliminated, but merely left undetermined. The Infinite (like the Finite, [Greek: to peperasmhenon—to hapeiron]) is a genus; it comprehends under it the Infinitely Hard and the Infinitely Soft, the Infinitely Swift and the Infinitely Slow—the infinite, in short, of any or all positive attributes. It includes, doubtless, 'a farrago of contradictions;' but so, also, does the Finite—and so, also, do the actual manifestations of the real, concrete universe, which manifestations constitute a portion of the Finite. Whoever attempts to give any philosophical account of the generation of the universe, tracing its phenomena, as an aggregate, to some ultra-phenomenal origin, must include in his scheme a fundamentum for all those opposite and contradictory manifestations which experience discloses in the universe. There always have been, and still are, many philosophers who consider the Abstract and General to be prior both in nature and time to the Concrete and Particular; and who hold further that these two last are explained, when presented as determinate and successive manifestations of the two first, which they conceive as indeterminate and sempiternal. Now the Infinite (Ens Infinitum or Entia Infinita, according to the point of view in which we look at it) is a generic word, including all these supposed indeterminate antecedents; and including therefore, of course, many contradictory agencies. But this does not make it senseless or unmeaning; nor can we distinguish it from 'the Infinite in some one or more given attributes,' by any other character than by greater reach of abstraction. We cannot admit the marked distinction which Mr Mill contends for—that the one is unknowable and the other knowable.

It may be proper to add that the mode of philosophizing which we have just described is not ours. We do not agree in this way either of conceiving, or of solving, the problem of philosophy. But it is a mode so prevalent that Trendelenberg speaks of it, justly enough, as 'the ancient Hysteron-Proteron of Abstraction.' The doctrine of these philosophers appears to us unfounded, but we cannot call it unmeaning.

In another point, also, we differ from Mr Mill respecting that inferior abstraction which he calls 'the Infinite in some particular attribute.' He speaks as if this could be known not only as an abstraction, a conceivable, an ideal—but also as a concrete reality; as if 'we could know a concrete reality as infinite or as absolute' (p. 45); as if there really existed in actual nature 'concrete persons or things possessing infinitely or absolutely certain specific attributes'—(pp. 55—93). To this doctrine we cannot subscribe. As we understand concrete reality, we find no evidence to believe that there exist in nature any real concrete persons or things, possessing to an infinite degree such attributes as they do possess: e.g. any men infinitely wise or infinitely strong, any horses infinitely swift, any stones infinitely hard. Such concrete real objects appear to us not admissible, because experience not only has not certified their existence in any single case, but goes as far to disprove their existence as it can do to disprove anything. All the real objects in nature known to us by observation are finite, and possess only in a finite measure their respective attributes. Upon this is founded the process of Science, so comprehensively laid out by Mr Mill in his 'System of Logic '—Induction, Deduction from general facts attested by Induction, Verification by experience of the results obtained by Deduction. The attributes, whiteness or hardness, in the abstract, are doubtless infinite; that is, the term will designate, alike and equally, any degree of whiteness or hardness which you may think of, and any unknown degree even whiter and harder than what you think of. But when perceived as invested in a given mass of snow or granite before us, they are divested of that indeterminateness, and become restricted to a determinate measure and degree.

Having thus indicated the points on which we are compelled to dissent from Mr Mill's refutation of Sir W. Hamilton in the pleading against M. Cousin, we shall pass to the seventh chapter, in which occurs his first controversy with Mr Mansel. This passage has excited more interest, and will probably be remembered by a larger number of readers, than any portion of the book. We shall give it in his own words (pp. 99—103), since the energetic phraseology is quite as remarkable as the thought:—

This concluding declaration is memorable in many ways. Mr Mill announces his resolution to determine for himself, and according to his own reason and conscience, what God he will worship, and what God he will not worship. For ourselves, we cordially sympathize with his resolution. But Mr Mill must be aware that this is a point on which society is equally resolved that no individual shall determine for himself, if they can help it. ^[6] Each new-born child finds his religious creed ready prepared for him. In his earliest days of unconscious infancy, the stamp of the national, gentile, phratric, God, or Gods, is imprinted upon him by his elders; and if the future man, in the exercise of his own independent reason, acquires such convictions as compel him to renounce those Gods, proclaiming openly that he does so—he must count upon such treatment as will go far to spoil the value of the present life to him, even before he passes to those ulterior liabilities which Mr Mill indicates in the distance. We are not surprised that a declaration so unusual and so impressive should have been often cited in critical notices of this volume; that during the month preceding the last Westminster election, it was studiously brought forward by some opponents of Mr Mill, and more or less regretted by his friends, as likely to offend many electors, and damage his chance of success; and that a conspicuous and noble-minded ecclesiastic, the Dean of Westminster, thought the occasion so grave as to come forward with his characteristic generosity, for the purpose of shielding a distinguished man suspected of heresy.

The sublime self-assertion, addressed by Prometheus to Zeus, under whose sentence he was groaning, has never before been put into such plain English. ^[7] Mr Mill's declaration reminds us also of Hippolytus, the chaste and pure youth, whose tragic fate is so beautifully described by Euripides. Hippolytus is exemplary in his devotions to the Goddess Artemis; but he dissents from all his countrymen, and determines for himself, in refusing to bestow the smallest mark of honour or worship upon Aphroditê, because he considers her to be a very bad Goddess. ^[8] In this refusal he persists with inflexible principle (even after having received, from an anxious attendant, warning of the certain ruin which it will bring upon him), until the insulted Aphroditê involves him, along with the unhappy Phædra and Theseus himself, in one common abyss of misery. In like manner Mr Mill's declaration stands in marked contrast with the more cautious proceeding of men like Herodotus. That historian, alike pious and prudent, is quite aware that all the Gods are envious and mischief-making, and expressly declares them to be so. ^[9] Yet, far from refusing to worship them on that account, he is assiduous in prayer and sacrifice—perhaps, indeed, all the more assiduous in consequence of what he believes about their attributes; ^[10] being persuaded (like the attendant who warned Hippolytus) that his only chance of mollifying their ungentle dispositions in regard to himself is, by honorific tribute in words and offerings.

When, however, after appreciating as we are bound to do Mr Mill's declaration of subjective sentiment, we pass to its logical bearing on the controversy between him and Mr Mansel, we are obliged to confess that in this point of view it has little objective relevancy. The problem was, how to reconcile the actual evil and suffering in the universe (which is recited as a fact by Mr Mansel, though in terms conveying a most inadequate idea of its real magnitude) with the goodness of God. Mr Mill repudiates the explanatory hypothesis tendered by Mr Mansel, as a solution, but without suggesting any better hypothesis of his own. For ourselves, we are far from endorsing Mr Mansel's solution as satisfactory; yet we can hardly be surprised if he considers it less unsatisfactory than no solution at all. And when we reflect how frequently and familiarly predicates applicable to man are applied to the Supreme Being, when they cannot possibly be understood about Him in the same sense—we see no ground for treating the proceeding as disingenuous, which Mr Mill is disposed to do. Indeed, it cannot easily be avoided: and Mr Mill himself furnishes us with some examples in the present volume. At page 491, he says:—

In the words here employed, seeing and hearing are predicted of God.

Now when we predicate of men, that they see or hear , we affirm facts of extreme complexity, especially in the case of seeing ; facts partly physical, partly mental, involving multifarious movements and agencies of nerves, muscles, and other parts of the organism, together with direct sensational impressions, and mental reconstruction of the past, inseparably associated therewith; all which, so far as they are known, are perspicuously enumerated in the work of Professor Bain ^[11] on the 'Senses and the Intellect,' Again, Mr Mill speaks (in p. 102 and elsewhere) of 'the veracity of God.' When we say of our neighbour that he is a veracious man, we ascribe to him a habit of speaking the truth; that is, of employing his physical apparatus of speech, and his mental power of recalling and recombining words lodged in the memory, for the purpose of asserting no other propositions except such as declare facts which he knows, or beliefs which he really entertains. But how either seeing , or hearing , or veracity , in these senses, can be predicated of God, we are at a loss to understand. And if they are to be predicated of God in a different sense, this admits the same license as Mr Mansel contends for in respect to Goodness, when he feels that undeniable facts preclude him from predicating that epithet univocally respecting God and respecting man. ^[12]

On the whole, it seems to us, that though Mr Mill will consent to worship only a God of perfect goodness, he has thrown no new light on the grave problem—frankly stated though imperfectly solved, by Mr Mansel—how such a conception of God is to be reconciled with the extent of evil and suffering actually pervading human life and animal life throughout the earth. We are compelled to say, respecting Mr Mill's treatment of this subject—what we should not say respecting his treatment of any other—that he has left an old perplexing problem not less perplexing than he found it.

Reverting, not unwillingly, from theology to philosophy, we now pass on to Mr Mill's ninth chapter (p. 128 seq.), of the Interpretation of Consciousness. There is assuredly no lesson more requiring to be taught than the proper mode of conducting such interpretation; for the number of different modes in which Consciousness has been interpreted is astonishing. Mr Mill begins by citing from Sir W. Hamilton's lectures a passage of some length, upon which he bestows considerable praise, regarding it as—

This is one of the greatest compliments to Sir W. Hamilton that the book contains, and as such we are glad to cite it.

On the subject of Consciousness, Mr Mill has cited from Sir W. Hamilton other good observations besides the one last alluded to; but, unfortunately, these are often neutralized by opposite or inconsistent opinions also cited from other parts of his works. The number of such inconsistencies produced is indeed one remarkable feature in Sir W. Hamilton's philosophical character. He seems to follow out energetically (as Plato in his various dialogues) the vein of thought pervading his mind at each particular moment, without troubling himself to look back upon his own prior speculations. Even compared with the best views of Sir W. Hamilton, however, Mr Mill's mode of handling the subject of Consciousness exhibits signal improvement. To some of his observations we shall call particular attention.

All philosophers agree that what Consciousness testifies is to be believed; but they differ much on the question—To what points Consciousness does testify? and even on the still deeper question—How shall we proceed to ascertain what are these attested points? What is the proper method of studying or interrogating Consciousness? Upon this Mr Mill remarks (pp. 145—147):—

This citation from Mr Mill's book is already almost too long, yet we could have wished to prolong it still more, from the importance of some of the succeeding paragraphs. It presents, in clear discrimination and contrast, two opposite points of view according to which the phenomena of mind are regarded by different philosophers, and the method of studying them determined: the introspective method, adopted by M. Cousin and others—the psychological or analytical method, pursued by Locke and by many other eminent men since Locke—'the known and approved method of physical science, adapted to the necessities of psychology'—(p. 148).

There are passages of Sir W. Hamilton's writings in which he appears to feel that the introspective method alone is insufficient for the interpretation of Consciousness, and that the analytical method must be employed to reinforce it. But on this as on other points he is not always consistent with himself. For in laying down the principle upon which the primary truths of Consciousness, the original data of intelligence, are to be ascertained and distinguished from generalizations out of experience and custom, he declares that the one single and certain mark is Necessity—they must be beliefs which we are under the necessity of believing—of which we cannot get rid by any mental effort. He decides this, of course, for himself, by the introspective method alone. He (with M. Cousin and other philosophers who take the same view) does not apply the analytical method to inquire whether his necessity of belief may not be a purely acquired necessity and nowise congenital. It is, indeed, remarkable that these philosophers do not even seek to apply the introspective method as far as that method will really go. They are satisfied with introspection of their own present minds; without collecting results of the like process as applied to other minds, in different times and places. They declare various beliefs to be necessary to the human mind universally, merely because such is the actual fact with their own minds and with those immediately around them; sometimes even in defiance of proof that there are (or have been) persons not sharing such beliefs, and occasionally even believing the contrary; therefore, when even the introspective method really disallows their affirmative instead of sustaining it. This is, in truth, an abuse of the introspective method; yet even if that method were employed in its fullest extent—if the same incapability of believing otherwise could be shown as common to all mankind—it might still be only the effect of a strong association. The analytical method must still be called in to ascertain whether we are forced to suppose such incapability to be an original fact of consciousness, or whether it may not have been generated in the mind by circumstances under the natural working of the laws of association. It is certain that these laws not only may, but must, give birth to artificial inconceivabilities in the mind—and that some of these may be equal in strength to such, if any, as are natural.

After various observations, chiefly exhibiting the rashness of many censures bestowed by Sir W. Hamilton on Brown, Mr Mill gives us three valuable chapters (xi., xii., xiii.), wherein he analyzes the belief in an External World, the Belief in Mind as a separate substance or Noumenon, and the Primary Qualities of Matter. To each of these topics he applies what he calls the psychological method, as contrasted with the simply introspective method of Sir W. Hamilton (the Ego and Non-Ego affirmed to be given together in the primary deliverance of Consciousness) and so many other philosophers. He proves that these beliefs are no way intuitive, but acquired products; and that the known laws of Association are sufficient to explain how they are acquired; especially the Law of Inseparable Association, together with that of Obliviscence —a very useful, discriminating phrase, which we first find employed in this volume—(p. 259 et passim). He defines Matter to be a permanent possibility of Sensation ; he maintains that this is really all which (apart from philosophical theories) mankind in general mean by it; he shows that mere possibilities of sensation not only may, but must, according to the known Laws of Association, come to present 'to our artificialized Consciousness' a character of objectivity—(pp. 198, 199). The correlative subject, though present in fact and indispensable, is eliminated out of conscious notice, according to the Law of Obliviscence.

These chapters will well repay the most careful perusal. We can only find room for one passage (pp. 214, 215):—

This chapter, on the Primary Qualities of Matter, controverts the opinion of Sir W. Hamilton, that extension, as consisting of co-existent partes extra partes , is immediately and necessarily apprehended by our consciousness. It cites, as well as confirms, the copious proof given by Professor Bain (in his work on the Senses and the Intellect) that our conception of extension is derived from our muscular sensibility: that our sensation of muscular motion impeded constitutes that of filled space: that our conception of extension, as an aggregate of co-existent parts, arises from the sense of sight, which comprehends a great number of parts in a succession so rapid as to be confounded with simultaneity—and which not only becomes the symbol of muscular and tactile succession, but even acquires such ascendancy as to supersede both of them in our consciousness. Confirmation is here given to this important doctrine, not merely by observations from Mr Mill himself, but also from the very curious narrative, discovered and produced by Sir W. Hamilton, out of a work of the German philosopher, Platner. Platner instituted a careful examination of a man born blind, and ascertained that this man did not conceive extension as an aggregate of simultaneous parts, but as a series of sensations experienced or to be experienced in succession—(pp. 232, 233). The case reported from Platner both corroborates the theory of Professor Bain, and receives its proper interpretation from that theory; while it is altogether adverse to the doctrine of Sir W. Hamilton—as is also another case, which he cites from Maine de Biran:—

We think this remark perfectly just; and we would point out besides, in appreciating Sir W. Hamilton's merits, that his appetite for facts was useful to philosophy, as well as his appetite for speculation. But the person whose usefulness to philosophy we prefer to bring into the foreground, is Platner himself. He spent three weeks in patient examination of this blind man, and the tenor of his report proves that his sagacity in interpreting facts was equal to his patience in collecting them. The rarity of all such careful and premeditated observation of the facts of mind, appears to us one main reason why (what Mr Mill calls) the psychological theory finds so little acceptance; and why those who maintain that what now seems a mental integer was once a multiplicity of separate mental fragments, can describe the antecedent steps of the change only as a latens processus , which the reader never fully understands, and often will not admit. Every man's mind is gradually built up from infancy to maturity; the process is always going on before our eyes, yet the stages of it—especially the earliest stages, the most pregnant with instruction—are never studied and put on record by observers trained in inductive logic, knowing beforehand what they ought to look for as the sine quâ non for proving or disproving any proposed theory. Such cases as that cited by Platner—cases of one marked congenital defect of sense, enabling us to apply the Method of Difference—are always within reach; but few Platners are found to scrutinize and record them. Historians of science describe to us the laborious and multiplied observations, and the elaborate precaution for ensuring accuracy of observation, which recent chemical and physical inquirers have found indispensable for the establishment of their results. We cannot, therefore, be surprised that mental philosophers, dealing with facts even more obscure, and careless about enlarging, varying, authenticating their records of particular facts, should have had little success in establishing any results at all.

But if even those, who adopt the psychological theory, have been remiss in the observation of particular mental facts,—those who deny the theory have been far more than remiss; they have been blind to obvious facts contradicting the principles which they lay down. Mr Mill, in chap, xiv., deals with this denial, common to Mr Mansel with Sir W. Hamilton. That philosophers so eminent as both of them should declare confidently—'what I cannot but think must be à priori , or original to thought; it cannot be engendered by experience upon custom' (p. 264)—appears to us as extraordinary as it does to Mr Mill. Though no one ever surpassed Sir W. Hamilton in large acquaintance with the actual diversities of human belief, and human incapacities of believing—yet he never seems to have thought of bringing this acquaintance into account, when he assured the students in his lecture-room, that custom, experience, indissoluble association, were altogether insufficient to engender a felt necessity of believing. Such forgetfulness of well-known mental facts cannot be reproached to the advocates of the psychological theory.

In chap. xv. Mr Mill examines Sir W. Hamilton's doctrine on unconscious mental modifications. He points out the confused manner in which Sir W. Hamilton has conceived mental latency , as well as the inconclusive character of the reasoning whereby he refutes the following doctrine of Dugald Stewart—That in the most rapid trains of association, each separate item must have been successively present to consciousness, though for a time too short to leave any memory. Sir W. Hamilton thinks that the separate items may pass, and often do pass, unconsciously; which opinion Mr Mill also, though not approving his reasons, is inclined to adopt.

Mr Mill gives various illustrations in support of this doctrine. He at the same time calls attention to a valuable lecture of Sir W. Hamilton's, the thirty-second lecture on Metaphysics; especially to the instructive citation from Cardaillac contained therein, noting the important fact, which descriptions of the Law of Association often keep out of sight—that the suggestive agency of Association is carried on, not by single antecedents raising up single consequents, but by a mass of antecedents raising up simultaneously a mass of consequents, among which attention is very unequally distributed.

We shall say little upon Mr Mill's remarks on Sir W. Hamilton's Theory of Causation—(chap. xvi.). This theory appears to Mr Mill absurd; while the theory of Mr Mill (continued from Hume, Brown, and James Mill) on the same subject, appears to Sir W. Hamilton insufficient and unsatisfactory—'professing to explain the phenomenon of causality, but, previously to explanation, evacuating the phenomenon of all that desiderates explanation'—(p. 295). For ourselves we embrace the theory of Mr Mill: ^[13] yet we are aware that the remark just cited from Sir W. Hamilton represents the dissatisfaction entertained towards it by many objectors. The unscientific and antiscientific yearnings, prevalent among mankind, lead them to put questions which no sound theory of Causation will answer; and they are ready to visit and trust any oracle which professes to deliver a confident affirmative solution of such questions. Among all the terms employed by metaphysicians, none is used in a greater variety of meanings than the term Cause.

In Mr Mill's next chapter (xvi.) he comments on Sir W. Hamilton's doctrine of Concepts or General Notions. There are portions of this chapter with which we agree less than with most other parts of the volume; especially with his marked hostility to the term Concept , and the reasons given for it, which reasons appear to us not very consistent with what he has himself said in the 'System of Logic,' Book IV. chap. ii. § 1—3. The term Concept has no necessary connection with the theory called Conceptualism. It is equally available to designate the idea called up by a general name, as understood either by Mr Bailey or by James Mill. We think it useful as an equivalent to the German word Begriff , which sense Sir W. Hamilton has in view when he introduces it, though he does not always adhere to his profession. And when Mr Mill says (p. 331)—

we dissent from his opinion. To talk of 'the Concept of an individual,' however, as Mr Mansel does (pp. 338, 339), is improper and inconsistent with the purpose for which the name is given.

We are more fully in harmony with Mr Mill in his two next chapters (xviii. et seq.) on Judgment and Reasoning; which are among the best chapters in this volume. He there combats and overthrows the theory of Reasoning laid down by Sir W. Hamilton; but we doubt the propriety of his calling this 'the Conceptualist theory' (pp. 367, 368); since it has nothing to do with Conceptualism, in the special sense of antithesis to Realism and Nominalism,—but is, in fact, the theory of the Syllogism as given in the Analytics of Aristotle, and generally admitted since. Not merely Conceptualists, but (to use Mr Mill's own language, p. 366) 'nearly all the writers on logic, taught a theory of the science too small and narrow to contain their own facts.' Such, indeed, was the theory constantly taught until the publication of Mr Mill's 'System of Logic;' the first two books of which corrected it, by arguments which are reinforced and amplified in these two chapters on Judgment and Reasoning, as well as in the two chapters next following—chaps, xx. and xxi.—('Is Logic the Science of the Forms of Thought—On the Fundamental Laws of Thought.') The contrast which is there presented, in many different ways, between the limited theory of logic taught by Sir W. Hamilton and Mr Mansel, and the enlarged theory of Mr Mill, is instructive in a high degree. We consider Mr Mill as the real preserver of all that is valuable in Formal Logic, from the unfortunate consequences of an erroneous estimate, brought upon it through the exaggerated pretensions of logicians. When Sir W. Hamilton contrasts it pointedly with physical science (of which he talks with a sort of supercilious condescension, in one of the worst passages of his writings, p. 401)—when all its apparent fruits were produced in the shape of ingenious but barren verbal technicalities—what hope could be entertained that Formal Logic could hold its ground in the estimation of the recent generation of scientific men? Mr Mill has divested it of that assumed demonstrative authority which Bacon called 'regere res per syllogismum;' but he has at the same time given to it a firm root amidst the generalities of objective science. He has shown that in the great problem of Evidence or Proof, the Laws of Formal Logic, though bearing only on one part of the entire procedure, yet bear upon one essential part, proper to be studied separately: and that the maintenance of consistency between our affirmations (which is the only special province of Formal Logic), has great importance and value as a part of the process necessary for ascertaining and vindicating their truth, or exposing their character when false or uncertified—but no importance or value except as a part of that larger exigency.

While Mr Mill was amending the Syllogistic theory so as to ensure for Formal Logic its legitimate place among the essentials of scientific procedure, Sir W. Hamilton was at the same time enlarging it on its technical side, in two modes which are highly esteemed both by himself and by others: 1. The recognition of two kinds of Syllogisms; one in Extension, the other in Comprehension: 2. The doctrine of the Quantification of the Predicate.—Both these novelties are here criticised by Mr Mill in chapter xxii., which we recommend the reader to peruse conjointly with Lectures 15 and 16 of Sir W. Hamilton on Logic.

Now whereas the main objection, by which the study of the syllogistic logic has been weighed down and discredited in modern times, is this, that it encumbers the memory with formal distinctions, having no useful application to the real process and purposes of reasoning—the procedure of Sir W. Hamilton might almost lead us to imagine that he himself was trying to aggravate that objection to the uttermost. He introduces a variety of new canons (classifying Syllogisms as Extensive and Intensive, by a distinction founded on the double quantity of notions, in Extension and in Comprehension) which he intimates that all former logicians have neglected—while it plainly appears, even on his own showing, that the difference between syllogisms, in respect to these two sorts of quantity, is of no practical value; and that 'we can always change a categorical syllogism of the one quantity into a categorical syllogism of the other, by reversing the order of the two premises, and by reversing the meaning of the copula' (Lect. xvi. p. 296); nay, that every syllogism is already a syllogism in both quantities (Mill, p. 431). Against these useless ceremonial reforms of Sir W. Hamilton, we may set the truly philosophical explanation here given by Mr Mill of the meaning of propositions.

From the lucid explanation here cited (and from a following paragraph too long to describe p. 433), we see that there is no real distinction between Judgments in Comprehension and Judgments in Extension; that the appearance of distinction between them arises from the customary mode of enunciation, which custom is here accounted for; that the addition to the theory of the Syllogism, for which Sir W. Hamilton takes credit, is alike troublesome and unprofitable.

The like may also be said about his other innovation, the Quantification of the Predicate. Still more extensive are the changes (as stated by himself) which this innovation would introduce in the canons of Syllogism. Indeed, when we read his language (Appendix to 'Lectures on Logic,' pp. 291—297) censuring generally the prior logicians from Aristotle downwards, and contending that 'more than half the value of logic had been lost' by their manner of handling it—we may appreciate the magnitude of the reform which he believed himself to be introducing. The larger the reform, the more it behoved him to be sure of the ground on which he was proceeding. But on this point we remark a serious deficiency. After laying down, with appropriate emphasis, the valuable logical postulate, to state explicitly what is thought implicitly , on which, Sir W. Hamilton says,

Here Sir W. Hamilton assumes that the quantity of the predicate is always understood in thought; and the same assumption is often repeated, in the Appendix to his 'Lectures on Logic,' p. 291 and elsewhere, as if it was alike obvious and incontestable. Now it is precisely on this point that issue is here taken with Sir W. Hamilton. Mr Mill denies altogether (p. 437) that the quantity of the predicate is always understood or present in thought, and appeals to every reader's consciousness for an answer:—

The last sentence cited from Mr Mill indicates the vice of Sir W. Hamilton's proceeding in quantifying the predicate, and explains why it was that logicians before him declined to do so. Sir W. Hamilton, in this proceeding, insists on stating explicitly, not merely all that is thought implicitly, but a great deal more; ^[14] adding to it something else, which may , indeed, be thought conjointly, but which more frequently is not thought at all. He requires us to pack two distinct judgments into one and the same proposition: he interpolates the meaning of the Propositio Conversa simpliciter into the form of the Propositio Convertenda (when an universal Affirmative), and then claims it as a great advantage, that the proposition thus interpolated admits of being converted simpliciter , and not merely per accidens . Mr Mill is, nevertheless, of opinion (pp. 439-443) that though 'the quantified syllogism is not a true expression of what is in thought, yet writing the predicate with a quantification may be sometimes a real help to the Art of Logic.' We see little advantage in providing a new complicated form, for the purpose of expressing in one proposition what naturally throws itself into two, and may easily be expressed in two. If a man is prepared to give us information on one Quaesitum, why should he be constrained to use a mode of speech which forces on his attention at the same time a second and distinct Quaesitum—so that he must either give us information about the two at once, or confess himself ignorant respecting the second?

The two next chapters of Mr Mill, noticing some other minor peculiarities (all of them unfortunate, and one, p. 447, really unaccountable) of Sir W. Hamilton's Formal Logic; and some Fallacious Modes of Thought countenanced by Sir W. Hamilton (chs. xxiii., xxiv.—pp. 446, 478), we are compelled to pass over. We must find space, however, for a few words on the Freedom of the Will (ch. xxv.), which (in Mr Mill's language, pp. 488—549), 'was so fundamental with Sir W. Hamilton, that it may be regarded as the central idea of his system—the determining cause of most of his philosophical opinions.' Prior to Sir W. Hamilton, we find some writers who maintain the doctrine of Free-will, others who maintain that of Necessity: each supporting their respective conclusions by reasons which they deem sufficient. Sir W. Hamilton declares that both the one doctrine and the other are inconceivable and incomprehensible; yet that, by the law of Excluded Middle, one or other of them must be true: and he decides in favour of Free-will, of which he believes himself to be distinctly conscious; moreover, Free-will is essential (he thinks) to moral responsibility, of which also he feels himself conscious. He confesses himself, however, unable to explain the possibility of Free-will; but he maintains that the same may be said about Necessity also. 'The champions of both the two opposite doctrines are at once resistless in attack, and impotent in defence'—(Hamilton's 'Footnotes on Reid,' p. 602.) Mr Mansel also asserts, even more confidently than Sir W. Hamilton, that we are directly conscious of Free-will—(p. 503).

Sir W. Hamilton has himself given some of the best arguments against the doctrine of Free-will, in refutation of Reid: arguments, some of which are here cited by Mr Mill with praise which they well deserve—(pp. 497, 498). But Mr Mill's own reasoning on the same side is of a still higher order, enlarging the grounds previously urged in the last book of his 'System of Logic,' He protests against the term Necessity ; and discards the idea of Necessity, if it be understood to imply anything more than invariability of antecedence and consequence. If it mean that , experience proves thus much about antecedents in the world of mind, as in the world of matter: if it mean more, experience does not prove more, either in the world of matter or in the world of mind: nor have we any grounds for affirming it in either—(p. 501.) If it were true, therefore, that consciousness attested Free-will, we should find the testimony of consciousness opposed to a full proof from experience and induction. But does consciousness really attest what is called Free-will? Mr Mill analyzes the case, and declares in the negative.

After this salutary and much-needed warning against the confusion between consciousness as an infallible authority, and belief upon experience, of which we are conscious as a belief—Mr Mill proceeds to sift the alleged self-evident connection between Free-will and Accountability. He shows, not merely that there is no connection, but that there is a positive repugnance, between the two. By Free-will is meant that a volition is not determined by motives, but is a spontaneous mental fact, neither having a cause, nor admitting of being predicted. Now, the very reason for giving notice that we intend to punish certain acts, and for inflicting punishment if the acts be committed, is, that we trust in the efficacy of the threat and the punishment as deterring motives. If the volition of agents be not influenced by motives, the whole machinery of law becomes unavailing, and punishment a purposeless infliction of pain. In fact, it is on that very ground that the madman is exempted from punishment; his volition being presumed to be not capable of being acted upon by the deterring motive of legal sanction. The free agent, thus understood, is one who can neither feel himself accountable, nor be rendered accountable, to or by others. It is only the necessary agent (the person whose volitions are determined by motives, and, in case of conflict, by the strongest desire or the strongest apprehension) that can be held really accountable, or can feel himself to be so.

It thus appears that of the two propositions, 1, volitions are necessary, or depend on causes; 2, volitions are free, or do not depend on causes—neither the one nor the other is inconceivable or incomprehensible, as Sir W. Hamilton supposed them to be. That the first is true, and the second false, we learn by experience, and by that alone; just as we learn the like in regard to the phenomena of the material world. Indeed, the fact that human volitions are both predictable and modifiable, quite as much as all those physical phenomena that depend upon a complication of causes—which is only a corollary from what has just been said—is so universally recognized and acted upon by all men, that there would probably be little difference of opinion about this question, if the antithesis were not obscured and mystified by the familiar, but equivocal, phrases of Free-will and Necessity.

Passing over chapter xxvii., in which Mr Mill refutes Sir W. Hamilton's opinion that the study of mathematics is worthless, or nearly so, as an intellectual discipline—we shall now call attention to the concluding remarks which sum up the results of the volume. After saying that he 'differs from almost everything in Sir W. Hamilton's philosophy, on which he particularly valued himself, or which is specially his own,' Mr Mill describes Sir W. Hamilton's general merits as follows:—

Agreeing in this general view of Sir W. Hamilton's merits, we should be disposed to describe them in language stronger and more emphatic as to degree, than that which has just been cited. But what is stated in the pages immediately following (pp. 550, 551)—That Sir W. Hamilton's doctrines appear to be usually taken up under the stimulus of some special dispute, and often afterwards forgotten; That he did not think out subjects until they were thoroughly mastered, or until consistency was attained between the different views which the author took from different points of observation; That accordingly, his philosophy seems made up of scraps from several conflicting metaphysical systems—All this is literally and amply borne out by the many inconsistencies and contradictions which Mr Mill has brought to view in the preceding chapters. It would appear that the controversial disposition was powerful with Sir W. Hamilton, and that a present impulse of that sort (as has been said respecting Bayle, Burke, and others) not only served to provoke new intellectual combinations in his mind, but also exercised a Lethæan influence in causing obliviscence of the old. But we can hardly follow Mr Mill in ascribing the defect to 'excessive absorption of time and energy by the study of old writers' (p. 551). If this study did no other good, it at least kept the memory in exercise. Now, what surprises us most in Sir W. Hamilton's inconsistencies, is the amount of self-forgetfulness which they imply.

While the laborious erudition of Sir W. Hamilton cannot be fairly regarded as having produced any of his intellectual defects, it undoubtedly stamped upon him his special title of excellence as a philosopher. This is fully recognized by Mr Mill; though he treats it as belonging not so much to a philosopher as to an historian of philosophy. He concludes (pp. 552—554):—

Here we find in a few sentences the conclusion which Mr Mill conceives to be established by his book. We shall state how far we are able to concur with it. He has brought the matter to a direct issue, by weighing Sir W. Hamilton in the balance against two other actual cotemporaries; instead of comparing him with some unrealized ideal found only in the fancy of critics and reviewers.

Comparing Sir W. Hamilton with Dr Brown, we cordially subscribe to the opinion of Mr Mill. We think that Dr Brown has 'done far greater service to the world than Sir W. Hamilton, in the origination and diffusion of important thought.' To speak only of two chief subjects in the field of important thought—Causality and the Freedom of the Will—we not only adopt the conclusions of Dr Brown, but we admire both his acuteness and his originality in vindicating and illustrating the first of the two, while we dissent entirely from the views of Sir W. Hamilton. This alone would be sufficient to make us approve the superiority assigned by Mr Mill to Dr Brown. We discover no compensating item to be placed to the credit of Sir W. Hamilton: for the great doctrine of the Relativity of Knowledge, which is our chief point of philosophical brotherhood with him, was maintained by Brown also.

But in regard to Dr Whately, our judgment is altogether different. We cannot consent to admit him as a superior, or even as an equal, to Sir W. Hamilton, 'in the origination and diffusion of important thought.' He did much service by reviving an inclination and respect for Logic, and by clearing up a part of the technical obscurity which surrounded it: but we look upon him as an acute and liberal-minded English theologian, enlarging usefully, though timidly, the intellectual prison in which many orthodox minds are confined—rather than as a fit aspirant to the cosmopolitan honours of philosophy. 'An active and fertile thinker,' Mr Mill calls Whately; and such he undoubtedly was. But such also we consider Sir W. Hamilton to have been in a degree, at least equal. If the sentence which we have quoted above be intended to deny the predicate, 'active and fertile thinker,' of Sir W. Hamilton, we cannot acquiesce in it. His intellect appears to us thoroughly active and fertile, even when we dissent from his reasonings—nay, even in the midst of his inconsistencies, when a new growth of opinions is unexpectedly pushed up on ground which we supposed to be already pre-occupied by another both older and different. And we find this same judgment implied in the discriminating remarks upon his philosophical procedure made by Mr Mill himself—(pp. 271, 272). For example, respecting Causality and the Freedom of the Will, we detect no want of activity and fertility, though marked evidence of other defects—especially the unconditional surrender of a powerful mind to certain privileged inspirations, worshipped as 'necessities of thought.'

While thus declaring how far we concur in the parallel here drawn of Sir W. Hamilton with Brown and Whately, we must at the same time add that the comparison is taken under circumstances unduly favourable to these two last. There has been no exposure of their errors and inconsistencies, equal in penetration and completeness to the crushing volume which Mr Mill has devoted to Sir W. Hamilton. To make the odds fair, he ought to furnish a similar systematic examination to Brown and Whately; enabling us to read their works (as we now do those of Sir W. Hamilton) with the advantage of his unrivalled microscope, which detects the minutest breach or incoherence in the tissue of reasoning—and of his large command of philosophical premisses, which brings into full notice what the author had overlooked. Thus alone could the competition between the three be rendered perfectly fair.

We regret, as Mr Mill does, that Sir W. Hamilton did not undertake the composition of a history of philosophy. Nevertheless we must confess that we should hardly feel such regret, if we could see evidence to warrant Mr Mill's judgment (p. 554) that Sir W. Hamilton was 'indifferent to the [Greek: dihoti] of a man's opinions, and that he was incompetent to draw up an estimate of the opinions of any great thinker,' &c. Such incompetence, if proved to be frequent and considerable, would deprive an author of all chance of success in writing a history of philosophy. But the study of Sir William Hamilton's works does not prove it to us, though Mr Mill has convicted him of an erroneous estimate of Leibnitz. We say frequent and considerable , because no historian of philosophy is exempt from the defect more or less; or rather (to pass out of the self-confidence of the Absolute into the modesty of the Relative) we seldom find any historian whose estimate of great philosophical thinkers does not often differ from our own. Hence we are glad when ample original extracts are produced, enabling us to test the historian, and judge for ourselves—a practice which Sir W. Hamilton would have required no stimulus to enforce upon him. There ought, indeed, to be various histories of philosophy, composed from different points of view; for the ablest historian cannot get clear of a certain exclusiveness belonging to himself. But, so far as we can conjecture what Sir W. Hamilton would or could have done, we think that a history of philosophy composed by him would have surpassed any work of the kind in our language.

We trust that Sir W. Hamilton's works will long continue to be read, along with Mr Mill's examination of them; and we should be glad if the works of other philosophers could be read along with a comment of equal acuteness and impartiality. Any point of view which could command the adherence of such a mind as Sir W. Hamilton's, deserves to be fully considered. Moreover, the living force of philosophy, as directress of human intelligence, depends upon keeping up in each of her devotees a full mastery of many divergent and opposite veins of reasoning—a knowledge, negative and affirmative, of the full case of opponents as well as of his own.

It is to Philosophy alone that our allegiance is sworn; and while we concur mostly with Mr Mill's opinions, we number both him and Sir W. Hamilton as a noble pair of brethren, serving alike in her train.

Amicus Hamilton; magis amicus Mill; amica ante omnes Philosophia. FOOTNOTES:
