The investigation of this last element is of paramount importance for the purpose we have in hand, since, without some ascertained principles and conditions of truth, men may fold their hands and view all behind and above the moving diorama of present impressions as ideas sublime but hopeless[43]—too high for us, who surely can never attain to them. The plan, therefore, of this essay is to take from the point now reached a fresh start—to set out, not from a consideration of what we may desire to know, but of how much or how little can be known, and the conditions of our knowing it.

An honest wish to be sure of one single thing soon shows us the impediments we meet in making quite sure of anything. Soon, also, we painfully learn that these impediments arise from two persistent sets of causes. Difficulties on the one hand occasioned by the obscurity, complication, or many-sidedness of objects actually existing in rerum naturâ. Difficulties on the other hand, which, like barnacles and remoræ attached to a good ship's wooden bottom, act as drags and retardations on our own apprehending faculties. Barnacle-like, they can only be kept at a distance or detached by carefully-devised contrivances. And these again give rise to troubles of other kinds,—just as copper-sheathed keels or iron vessels are not without their drawbacks.

The inquiry we propose will have a great collateral advantage, both to him who doubts and to him who accepts Theism. For we shall at least get rid of what may fairly be termed a stupid prejudice. Persons who read and think little, are apt to base upon their own ignorance a vague presumption that the path of knowledge is plain and easy, until men try to know God. Then all is hard; the pleasant path becomes a rough and toilsome road. Others who read, but think less than they read, are aware that very real obstacles beset all deep inquiry, yet form hazy and imperfect notions as to the true extent of those obstacles. They little think how often we are all obliged to accept and maintain first truths;—difficulties objective, and difficulties subjective, notwithstanding.

Of one practical conclusion resulting from these difficulties, we may feel assured beforehand. Many objects of the greatest interest and importance to truth can never be truly known as they are in themselves;—our utmost hope is to know, not them, but as much as we can discover respecting them. And sometimes this limited knowledge is invaluable. If it does not gratify our natural desire for speculation, it may often guide and govern our lives. Unspeakably important, for example, in itself and in its consequences, must be an affirmative answer to our anxious question concerning the existence of a God.

Corollary.—It plainly appears from what has been said, that the knowledge of an "efficient cause" (in physics) does not, and cannot, at all preclude the inquiry after a purpose or "final cause"; but, on the contrary, leads to its investigation. In a watch's action, the former is represented by the moving power—that is, the spring; the latter, by the watch's function—that of indicating hours, minutes, and seconds. Would any uninformed person, examining a watch for the first time, and knowing no more than what he sees,—be able to give to himself any real account of the watch, if spring, train of wheel-work, and pointers, were shown him; but no hint given of the purpose and object of the whole construction? Now, to tell him this, would be to convey the idea,—a principle which resides in Mind, and in Mind alone;—and, so residing, leads to intelligent adaptation;—that is, a law or laws apprehended by the active exercise of certain mental faculties.

Let the intelligent reader ask himself whether any functional structure can be comprehended on any lower terms?—As however this latter question will be fully discussed further on, it is unnecessary to say more respecting it at present.

ADDITIONAL NOTES AND ILLUSTRATIONS TO CHAPTER II.

A.—ON THE ABSTRACT REASONINGS INVOLVED IN NATURAL THEOLOGY.

In a foot-note, Lord Brougham adds:—"It is worthy of observation that not the least allusion is made in Dr. Paley's work to the argument here stated, although it is the foundation of the whole of Natural Theology. Not only does this author leave entirely untouched the argument à priori (as it is called), and also all the inductive arguments derived from the phenomena of mind, but he does not even advert to the argument upon which the inference of design must of necessity rest—that design which is the whole subject of his book. Nothing can more evince his distaste or incapacity for metaphysical researches. He assumes the very position which alone sceptics dispute. In combating him they would assert that he begged the whole question; for certainly they do not deny, at least in modern times, the fact of adaptation. As to the fundamental doctrine of causation, not the least allusion is ever made to it in any of his writings,—even in his Moral Philosophy."

It is when reviewing this last-named treatise that Dr. Whewell remarks (History of Moral Philosophy, p. 169):—

"The fact is that Paley had no taste, and therefore we may be allowed to say that he had little aptitude, for metaphysical disquisitions. In this there would have been no blame, if he had not entered into speculations which, if they were not metaphysically right, must be altogether wrong. We often hear persons declare that they have no esteem for metaphysics, and intend to shun all metaphysical reasonings; and this is usually the prelude to some specimen of very bad metaphysics: for I know no better term by which to designate the process of misunderstanding and confounding those elements of truth which are supplied by the relations of our own ideas. That Paley had no turn or talent for the reasoning which depends on such relations, is plain enough."

The reader may with little trouble collect for himself what is meant by bad metaphysics from the following extracts. The first is Lord Macaulay's criticism on the metaphysics of the Schools, which he introduces into his essay on Francis Bacon, as follows:—

"By stimulating men to the discovery of useful truth, he" (Bacon) "furnished them with a motive to perform the inductive process well and carefully. His predecessors had been, in his phrase, not interpreters, but anticipators of nature. They had been content with the first principles at which they had arrived by the most scanty and slovenly induction. And why was this? It was, we conceive, because their philosophy proposed to itself no practical end—because it was merely an exercise of the mind. A man who wants to contrive a new machine or a new medicine has a strong motive to observe accurately and patiently, and to try experiment after experiment. But a man who merely wants a theme for disputation or declamation has no such motive. He is therefore content with premises grounded on assumption, or on the most scanty and hasty induction. Thus, we conceive, the schoolmen acted. On their foolish premises they often argued with great ability; and as their object was "assensum subjugare, non res" (Nov. Org. I. Aph. 29), to be victorious in controversy, not to be victorious over nature, they were consistent. For just as much logical skill could be shown in reasoning on false as on true premises."[44] Of course, if any genuine metaphysical philosophy exists at all, its right and real object must be to try and discover true premises of the more abstract sort—premises, the truth of which affects the procedure of all the ancillary series.[45]

Our next quotation contains Hume's sentence of execution rather than critique upon metaphysics as he saw them in connection with dogmatic theology. First, for his fiery anathema:—

"When we run over libraries, persuaded of these principles, what havoc must we make? If we take in our hand any volume of divinity or School metaphysics, for instance, let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning concerning matters of fact and existence? No. Commit it then to the flames: For it can contain nothing but sophistry and illusion." (Inquiry concerning Human Understanding, § XII.) Alas for certain of Hume's own speculations!

The student of Positivism knows how this fierce invective was echoed and re-echoed by Comte and his followers. They, however, omitted the qualifying word "School," which Hume prefixed to metaphysics. With Comte, metaphysic of every kind was "anathema maranatha"; and even psychology got excommunicated, by way of making "a clean sweep."

Hume, on the contrary, had an idea of what philosophy ought to be, and thus outlined his preparation for a Metaphysic of the Future:—

"The only method of freeing learning, at once, from these abstruse questions, is to inquire seriously into the nature of human understanding, and show, from an exact analysis of its powers and capacity, that it is by no means fitted for such remote and abstruse subjects. We must submit to this fatigue in order to live at ease ever after: and must cultivate true metaphysics with some care, in order to destroy the false and adulterate. Indolence, which, to some persons, affords a safeguard against this deceitful philosophy, is, with others, overbalanced by curiosity; and despair, which at some moments prevails, may give place afterwards to sanguine hopes and expectations. Accurate and just reasoning is the only catholic remedy, fitted for all persons and all dispositions; and is alone able to subvert that abstruse philosophy and metaphysical jargon, which, being mixed up with popular superstition, renders it in a manner impenetrable to careless reasoners, and gives it the air of science and wisdom.

"Besides this advantage of rejecting, after deliberate inquiry, the most uncertain and disagreeable part of learning, there are many positive advantages, which result from an accurate scrutiny into the powers and faculties of human nature. It is remarkable concerning the operations of the mind, that though most intimately present to us, yet, whenever they become the object of reflection, they seem involved in obscurity; nor can the eye readily find those lines and boundaries which discriminate and distinguish them. The objects are too fine to remain long in the same aspect or situation, and must be apprehended, in an instant, by a superior penetration, derived from nature, and improved by habit and reflection. It becomes, therefore, no inconsiderable part of science barely to know the different operations of the mind, to separate them from each other, to class them under their proper heads, and to correct all that seeming disorder in which they lie involved, when made the object of reflection and inquiry. This task of ordering and distinguishing, which has no merit when performed with regard to external bodies, the objects of our senses, rises in its value when directed towards the operations of the mind, in proportion to the difficulty and labour which we meet with in performing it. And if we can go no farther than this mental geography, or delineation of the distinct parts and powers of the mind, it is at least a satisfaction to go so far; and the more obvious this science may appear (and it is by no means obvious), the more contemptible still must the ignorance of it be esteemed, in all pretenders to learning and philosophy." Ibid. Section I.

It seems worth while to consider what the effects might have been, had Hume been faithful to his own idea.[46] In the first place he would have remedied the weakness pointed out by Macaulay in the premises of the schoolmen, which were in fact little better than sententious maxims often derived from mistranslated passages of Scripture, one-sided opinions of the Fathers, and other sources of doubtful value. These, Hume would have abscided altogether, and rested his "true metaphysics" upon such principles as survived a searching inquiry into the conditions of Human knowledge. Hence, secondly, he would have rendered a great service to Divinity itself, which can never be benefited by such arguments as have been described, but must look for a safe alliance to a synthesis of Faith and Reason. And in the third place he might have probably given to his country a critical Philosophy adapted to English modes of Thought. Kant's mind was fired by a spark of Hume's kindling, but when we think what might have been the shape and acceptance of Kant in this country had Hume heralded him by a critique of Reason, it is impossible to read the great Scotchman's writings without a feeling of disappointment.[47]

It would however be unjust to omit the fact that Hume did really entertain a serious intention of dealing with these difficult questions. Thus much is expressed in his earliest work, and we may conjecture that literary disappointment was at least one cause of that later preference for "easy philosophy" which contrasts so strongly with the programme of his treatise on Human Nature. Few programmes were ever more vigorously outlined, than the ensuing.

"From hence," he says, "in my opinion, arises that common prejudice against metaphysical reasonings of all kinds, even amongst those who profess themselves scholars, and have a just value for every other part of literature. By metaphysical reasonings, they do not understand those on any particular branch of science, but every kind of argument, which is any way abstruse, and requires some attention to be comprehended. We have so often lost our labour in such researches, that we commonly reject them without hesitation, and resolve, if we must for ever be a prey to errors and delusions, that they shall at least be natural and entertaining. And, indeed, nothing but the most determined scepticism, along with a great degree of indolence, can justify this aversion to metaphysics. For, if truth be at all within the reach of human capacity, 'tis certain it must lie very deep and abstruse; and to hope we shall arrive at it without pains, while the greatest geniuses have failed with the utmost pains, must certainly be esteemed sufficiently vain and presumptuous. I pretend to no such advantage in the philosophy I am going to unfold, and would esteem it a strong presumption against it, were it so very easy and obvious."—Treatise on Human Nature, Introduction, p. 12.

In these sentences Hume has sufficiently condemned the vulgar objections brought against abstract reasoning. Deep and difficult questions can be discussed in no other manner; and what is often called a popular treatise on some subject of philosophic inquiry can never be more than a statement of its writer's opinions, or possibly of his sentimental prejudices.

The next paragraph contains Hume's earliest[48] sketch of that critical inquiry into Human Nature on which he proposed to base all future philosophy. It is of course deeply interesting.

"'Tis evident that all the sciences have a relation, greater or less, to human nature; and that however wide any of them may seem to run from it, they still return back by one passage or another. Even Mathematics, Natural Philosophy, and Natural Religion, are in some measure dependent on the science of Man; since they lie under the cognizance of men, and are judged of by their powers and faculties.

"'Tis impossible to tell what changes and improvements we might make in these sciences were we thoroughly acquainted with the extent and force of human understanding, and could explain the nature of the ideas we employ, and of the operations we perform in our reasonings. And these improvements are the more to be hoped for in natural religion, as it is not content with instructing us in the nature of superior powers, but carries its views further, to their disposition towards us, and our duties towards them; and consequently we ourselves are not only the beings that reason, but also one of the objects concerning which we reason."

"If, therefore, the sciences of mathematics, natural philosophy, and natural religion, have such a dependence on the knowledge of man, what may be expected in the other sciences, whose connection with human nature is more close and intimate?... In these four sciences of Logic, Morals, Criticism, and Politics, is comprehended almost everything which it can any way import us to be acquainted with, or which can tend either to the improvement or ornament of the human mind.

"Here then is the only expedient, from which we can hope for success in our philosophical researches, to leave the tedious lingering method, which we have hitherto followed, and instead of taking now and then a castle or village on the frontier, to march up directly to the capital or centre of these sciences, to human nature itself; which being once masters of, we may everywhere else hope for an easy victory. From this station we may extend our conquests over all those sciences which more intimately concern human life, and may afterwards proceed at leisure to discover more fully those which are the objects of pure curiosity. There is no question of importance, whose decision is not comprised in the science of man; and there is none, which can be decided with any certainty, before we become acquainted with that science. In pretending, therefore, to explain the principles of human nature, we in effect propose a complete system of the sciences, built on a foundation almost entirely new, and the only one upon which they can stand with any security."[49] Ibid. pp. 13-14.

The present writer has a special interest in citing these passages, because they do in fact defend as well as describe the procedure of his very next chapter.

Such then at an early age was Hume's keen-edged critical appreciation of those intellectual conditions required for a Philosophy of the Sciences, or as he calls it, the "true Metaphysics." In order to supplement his clever and clear idea by a very practical delineation of the metaphysical territory, we turn to another great thinker, the founder of our modern natural science, the great Lord Verulam.[50]

Bacon divides Philosophy according to its objects, which are three,—God, Nature, Man. Take, then, Natural Philosophy; it is well said that the truth of nature lies deeply hidden, and it is also well said that the Producer imitates Nature. Natural Philosophy divides itself accordingly into the inquisition of causes and the production of effects; it is both speculative and operative. There is indeed an intercourse between causes and effects, and both these kinds of knowledge. All true and fruitful Natural Philosophy has a double scale or ladder,—ascendent and descendent; ascending from experiment to first causes; descending thence to fresh experiment and always fresh productiveness.[51]

The ascending half is divided into two moieties, of which one is the science of Physics, the other of Metaphysics. In distinguishing these two, Bacon so far agrees with antiquity as to say,—"That Physic supposes in nature only a being and moving and natural necessity; whereas Metaphysic supposes also a Mind and Idea. For that which I shall say comes perhaps to this."[52] Or, to put it in another light, he writes elsewhere:—"Physique, taking it according to the derivation, and not according to our idiom for medicine, is situate in a middle term or distance between natural history and Metaphysique. For natural history describeth the variety of things; Physique, the causes, but variable or respective causes; and Metaphysique, the fixed and constant causes."[53]

In order to clear the way for his Metaphysic of the future, Bacon subjects what had been called by that name to a critical process. He separates from it a kind of theoretical philosophy, the attainment of which he considered doubtful, though he desired that it should be attempted, as the ultimate goal of human wisdom. The object of the separation is, therefore, to leave his metaphysical science within the limits of what is certainly attainable,—a fact not to be lost sight of in its relation to the abstract subjects in which we are now specially interested. The separated realm of knowledge Bacon calls "First and Summary Philosophy"; it is a "common ancestor to all knowledge,"[54] whereas Metaphysic belongs to the philosophy of Nature. It is at the apex of his pyramid of knowledges,[55]—the basis being a collection of natural facts—the "stage next the basis," (an investigation of causes variable and immersed in material existence,) is called "Physique—the stage next the vertical point is Metaphysique."[56] To enter clearly into Bacon's meaning, two questions should be answered: one, what was the wisdom that older Metaphysicians pursued, respecting which he did not himself feel sanguine? and the other, what remained in his thought the province of practical Metaphysique?

It is obvious that a wisdom which shall gather up all that every other realm of wisdom produces, cast it into Thought's winepress, and extract the rarest vintage of Truth, has been the vision of every age since men began to inquire and to reason. If this wisdom were possible, it would become to us an alphabet of the Universe; we should obtain a clear insight into the world as it is, and the foregone work of its Creator. Each of us might truthfully say:—

It needs but a glance at Bacon's indefinite outline of a First and Summary Philosophy,[57] to see that it must always be greeted by two opposite sentences of condemnation. A large section of its censors will pronounce the meagreness of its contents "a gentle riddance," or perhaps describe the contents themselves still more harshly as "rubbish shot here." Another section may compare all that it leaves for Metaphysics to the year without its spring, or Shakespeare's masterpiece of philosophy with the part of Hamlet left out.

Let us see then how the reserved province was parcelled out.—Bacon himself remarks:—"It may fairly therefore now be asked, what is left remaining for Metaphysic? Certainly nothing beyond nature; but of nature itself much the most excellent part." Most excellent because "Physic handles that which is most inherent in matter and therefore transitory, and Metaphysic that which is more abstracted and fixed. And again, that Physic supposes in nature only a being and moving and natural necessity: whereas Metaphysic supposes also a mind and idea."[58]

This search into the Mind of Nature is divided into the investigation of two kinds of causes, still called the Formal and the Final. Bacon's doctrine of Forms—the Philosophy in which is embraced "Natura naturans"—nature engendering nature—the Queen of Art—and the Regent of Production, constitutes one of the most difficult parts of the Novum Organum, the Advancement, and the De Augmentis; and may have been one chief provocative to King James' irreverent similitude. It might, according to some writers, even now prove a veritable "peace of God" could we only grasp its full meaning. "From the discovery of Forms," says Bacon, "results truth in speculation and freedom in operation."[59] And his latest commentator believes that this field of discovery has not been truly explored, because its very idea has been only imperfectly apprehended. The whole question, however, belongs to a future Chapter of this Essay, where we propose examining the Law of Production in its most refined and abstract shape. Yet one further remark may be allowed here. According to Francis Bacon, one "respect which ennobles this part of Metaphysic, is that it enfranchises the power of men to the greatest liberty, and leads it to the widest and most extensive field of operation.... For physical causes give light and direction to new inventions in similar matter. But whosoever knows any Form, knows also the utmost possibility of superinducing that nature upon every variety of matter, and so is less restrained and tied in operation, either to the basis of the matter or to the condition of the efficient."[60]

We are more concerned, at the present stage of this Essay, with the second portion of Bacon's Metaphysique—the Inquiry into Final Causes. They are described in the Advancement as not having been neglected before its great Author's time, but as having been "misplaced." "For they are," he writes in the De Augm. (E. & S. iv. p. 363) "generally sought for in Physic, and not in Metaphysic. And yet if it were but a fault in order I should not think so much of it; for order is matter of illustration, but pertains not to the substance of sciences. But this misplacing has caused a notable deficience, and been a great misfortune to Philosophy. For the handling of final causes in Physics has driven away and overthrown the diligent inquiry of physical causes." ... "And I say this, not because those final causes are not true and worthy to be inquired in metaphysical speculations; but because their excursions and irruptions into the limits of physical causes has bred a waste and solitude in that track. For otherwise, if they be but kept within their proper bounds, men are extremely deceived if they think there is any enmity or repugnancy at all between the two." (Ibid. p. 364.) Bacon's meaning is indeed clear enough to those who consider his examples. We do not learn how clouds are produced by being told they serve for watering the earth. It is no history of our earth itself, to say that its "solidness is for the station and mansion of living creatures." "To know the actual nature of a thing," observes an Oxford commentator on the Organum, "we must investigate it in and for itself, not for its results."[61]

Perhaps one of the most curious facts relating to the "misplacement" of Final Causes is that few more flagrant instances of that abuse can be found than some which occur in the field, not of physical but of moral science. The following remarkable example is from an argument framed by Mr. James Mill against Sir J. Macintosh, which appears all the more worthy of quotation, because it is reproduced and approved by Mr. J. Stuart Mill. The whole argument deserves perusal as showing how easily an acquired and customary kind of association will sometimes predominate over free thought; but for our present object a few passages will suffice. The italics are not Mr. Mill's, but are here marked for the purpose of guiding the reader's eye to those steps which lead from final cause (or motive) to interest, from interest to Utility in its grossest form, the artificial creation, namely, of our spur to interested action, dignified by this author with the sacred name of Morality, both in essence, i.e., what makes an act to be moral—and in respect of our moral sense, i.e., what are the sentiments with which we regard our own actions and those of other persons.

"Men make classifications, as they do everything else, for some end. Now, for what end was it that men, out of their innumerable acts, selected a class, to which they gave the name of moral, and another class, to which they gave the name of immoral? What was the motive of this act? What its final cause?

"Assuredly the answer to this question is the first step, though Sir James saw it not, towards the solution of his two questions, comprehending the whole of ethical science; first, what makes an act to be moral? and, secondly, what are the sentiments with which we regard it?

"We may also be assured, that it was some very obvious interest which recommended this classification; for it was performed, in a certain rough way, in the very rudest states of society.

"Farther, we may easily see how, even in very rude states, men were led to it, by little less than necessity.... They had no stronger interest than to obtain the repetition of the one sort, and to prevent the repetition of the other.... And here we clearly perceive the origin of that important case of classification, the classification of acts as moral and immoral. The acts, which it was important to other men that each individual should perform, but in which the individual had not a sufficient interest to secure the performance of them, were constituted one class. The acts, which it was important to other men that each individual should abstain from, but in regard to which he had not a personal interest sufficiently strong to secure his abstaining from them, were constituted another class. The first class were distinguished by the name moral acts; the second by the name immoral.

"The interest which men had in securing the performance of the one set of acts, the non-performance of the other, led them by a sort of necessity to think of the means. They had to create an interest, which the actor would not otherwise have, in the performance of the one sort, the non-performance of the other. And in proceeding to this end, they could not easily miss their way. They had two powers applicable to the purpose. They had a certain quantity of good at their disposal, and they had a certain quantity of evil.... And this is the scheme which they adopted; and which, in every situation, they have invariably pursued. The whole business of the moral sentiments, moral approbation, and disapprobation, has this for its object,—the distribution of the good and evil we have at command, for the production of acts of the useful sort, the prevention of acts of the contrary sort. Can there be a nobler object?"[62]

Some people may think that all nobleness is here taken away from moral distinctions. Others may wonder how such refined calculation could take place "in the very rudest states of Society." Many more will feel that this factitious interest is not the moral sentiment of which they are themselves conscious. We defer these points, however, to a future chapter, and are satisfied now with calling attention to the "misplacement" of final causes. To any modern versed (as Bacon was) in the wisdom of the mediæval schools, the following parallel might appear complete. Ask two questions—what are clouds?—what are moral distinctions?—let a "why" be substituted for the "what." Both are classified by men, both may be defined by their subserviency to human interests,—it is sufficient to discover some use in each. Moral distinctions exist for the benefit of society, clouds are for watering the earth. An earth-watering contrivance describes not only one use but the whole nature of a cloud; and for morality can a nobler definition be found than that of a notion invented and named on Utilitarian principles and promoting a public interest?[63] Doubtless morality does benefit mankind—doubtless clouds do water the earth. But in either case is the good effect its full and comprehensive "why?"—to say nothing of the desiderated "what?"

Francis Bacon (as we have seen) strongly affirmed that between Physical Causes and Final Causes "kept within their proper bounds, men are extremely deceived if they think there is any enmity or repugnancy at all." The manner in which, according to the Baconian doctrine, these two sets of causes harmonize and supplement each other, so as conjointly to subserve the highest purpose of Natural Theology, cannot be better explained than in the words of Bacon's late lamented Editor, Mr. R. Leslie Ellis:—

"It is not sufficiently remarked that final causes have often been spoken of without any reference to a benevolent intention. When it is said that the final cause of a stone's falling is 'locus deorsum,' the remark is at least but remotely connected with the doctrine of an intelligent providence. We are to remember that Bacon has expressly censured Aristotle for having made use of final causes without referring to the fountain from which they flow, namely the providence of the Creator. And in this censure he has found many to concur.

"Again, in any case in which the benevolent intention can be perceived, we are at liberty to ask by what means and according to what laws this benevolent intention is manifested and made efficient. If this question is not to be asked, there is in the first place an end of physical science, so far as relates to every case in which a benevolent intention has been or can be recognised; and in the second, the argument à posteriori founded on the contrivance displayed in the works of creation is entirely taken away.

"This is, in effect, what Bacon says in the passage of the De Augmentis, in which he complains of the abuse of final causes. If, he affirms, the physical cause of any phenomenon can be assigned as well as the final, so far is this from derogating from our idea of the divine wisdom, that on the contrary it does but confirm and exalt it."[64]

Before passing from this subject the reader's attention may be drawn to two notes by the same eminent commentator. Bacon remarks (Nov. Org. I. 48) that Final Causes are "ex naturâ hominis" i.e., have relation to the nature of Man. "It is difficult," writes Mr. Ellis, "to assent to the assertion that the notion of the final cause, considered generally, is more ex naturâ hominis than that of the efficient. The subject is one of which it is difficult to speak accurately; but it may be said that wherever we think that we recognise a tendency towards a fulfilment or realisation of an idea, there the notion of the final cause comes in. It can only be from inadvertence that Professor Owen has set the doctrine of the final cause as it were in antithesis to that of the unity of type: by the former he means the doctrine that the suitability of an animal to its mode of life is the one thing aimed at or intended in its structure. It cannot be doubted that Aristotle would have recognised the preservation of the type as not less truly a final cause than the preservation of the species or than the well-being of the individual. The final cause connects itself with what in the language of modern German philosophy is expressed by the phrase 'the Idea in Nature.'"[65]

The epigrammatic comparison of a Final Cause to a consecrated Virgin[66] has been reviewed by numberless disciples as well as critics of our author. Mr. Ellis annotates the Latin text thus:—"Nihil parit, means simply, non parit opera, which though it would have been a more precise mode of expression would have destroyed the appositeness of the illustration. No one who fairly considers the context can, I think, have any doubts as to the limitation with which the sentence in question is to be taken. But it is often the misfortune of a pointed saying to be quoted apart from any context, and consequently to be misunderstood." And this seems to be a scholarly explanation.[67]

To complete the sketch of Baconian Metaphysic it appears only needful to add that his respect for the science of Quantity is sufficient to make him class under this higher philosophy—this near approach to the apex of his Pyramid—the whole circle of Mathematics.

Our long note will not have been written in vain if the reader bears its contents in mind when considering the abstract arguments advanced throughout this Essay. It is well to see what very great authorities have thought concerning the true use of Metaphysics;—it is well also to see how they ought to be applied in questions of physical science, and for the purpose of grounding a science of Natural Theology.

B.—ON THE PHRASE "DESIGN IMPLIES A DESIGNER."

In his 23rd and 24th chapters, where some hasty writer might have said "law implies a lawgiver," the Archdeacon prefers to state that "a law pre-supposes an agent," and proceeds to argue the statement on its merits. "Law," he says, "is only the mode according to which an agent proceeds: it implies a power, for it is the order according to which that power acts. Without this agent, without this power, which are both distinct from itself, the 'law' does nothing; is nothing." (Chapter 23.) He is well satisfied with this argument also, and repeats it (slightly varied in form) during the course of his next chapter.

In our comparison of Powell with Paley we were led to remark on the diverse meanings of the word Design, and the facility with which some authors have glided from one to another among its significations. If any thinker believes that the examples he adduces are distinctly instances of Foresight, Intention, and Will, he has the Designer full in mind before he employs the term Design. But if his instances fall short of thus much implicit force, the argument founded on them is a worthless verbality.[68]

Those who protest against the popular phrase, "Design proves a Designer," say it is a temptation to assume this point—(the one point at issue)—over which it skims with such secure ease. But to any person in earnest, few things are more irritating than a piece of cool, thorough-going assumption. It is like catching a cat and persistently calling it a hare. Many visitors at certain Roman Hotels are aware that when deprived of ears and tail more Italico and well roasted, the resemblance between these two animals may give rise to questions of disputed identity. Imagine, now, a party of cat-catchers, who not only assume the Identity, but persevere in calling their mongrel curs harehounds, and themselves huntsmen. No truer claim in reality do a multitude of Design-hunters possess to any higher title than the leguleii of Natural Theology. And the blame of their discredit must in a great degree be laid upon their words. It is easy to say, "A thrown-stone implies a thrower." But suppose the stone about which you and I are talking was thrown by the fiery force of a volcano? Must we hence infer the existence of a Cyclops or a Titan?

This mode of popular speech reached the climax of absurdity when it was gravely argued that "Evolution implies an Evolver." So it might appear to the peculiar mind of the speaker; but how about the mind of him who promulgated the evolution-hypothesis? Stones (as we may observe) fly from more than one cause, and there is more than one account to be given of the theory of Evolution.

Enough has been said to show that the phrase commented on in this note, prejudices the argument it is intended to assist. It wears the appearance of embodying a foregone conclusion; and gives trouble to the honest inquirer, who, in order to estimate reasonings at their true value, must translate them into accurate forms of speech.

We may aptly finish these remarks by a quotation from Whewell's Aphorisms on the Language of Science. (Aphorism I., Philosophy of the Inductive Sciences, II. 483.) "Words borrowed from common language, and converted by scientific writers into technical terms, have some advantages and some disadvantages. They possess this great convenience, that they are understood after a very short explanation, and retained in the memory without effort. On the other hand they lead to some inconvenience; for since they have a meaning in common language, a careless reader is prone to disregard the technical limitation of this meaning, and to attempt to collect their import in scientific books, in the same vague and conjectural manner in which he collects the purpose of words in common cases. Hence the language of science, when thus resembling common language, is liable to be employed with an absence of that scientific precision which alone gives it value. Popular writers and talkers, when they speak of force, momentum, action, and reaction, and the like, often afford examples of the inaccuracy thus arising from the scientific appropriation of common terms."

A similar line of reflection led Coleridge to remark (Biog. Lit., Chap. x.) that "the language of the market would be in the schools as pedantic, though it might not be reprobated by that name, as the language of the schools in the market. The mere man of the world, who insists that no other terms but such as occur in common conversation should be employed in a scientific disquisition, and with no greater precision, is as truly a pedant as the man of letters, who, either over-rating the acquirements of his auditors, or misled by his own familiarity with technical or scholastic terms, converses at the wine-table with his mind fixed on his museum or laboratory." And such pedantry is, we may add, not uncommonly just as perspicuous as the definition which, says old Glanvill, "was lately given of a Thought in a University Sermon—viz. A Repentine Prosiliency jumping into Being." (Defence of the Vanity of Dogmatizing, Actio Decima, p. 61, ed. 1.)

C.—HUME ON THE ANALOGIES OF ART AND NATURE.

"The case is not the same with our reasonings from the works of nature. The Deity is known to us only by his productions, and is a single being in the universe, not comprehended under any species or genus, from whose experienced attributes or qualities, we can, by analogy, infer any attribute or quality in him." (Enquiry concerning Human Understanding. Section xi.)

Hume himself gives in his own character a reply partially veiled by the same half-metaphysical style which characterises the objection:—

"There occurs to me (continued I), with regard to your main topic, a difficulty which I shall just propose to you without insisting on it, lest it lead into reasonings of too nice and delicate a nature. In a word, I much doubt whether it be possible for a cause to be known only by its effect (as you have all along supposed), or to be of so singular and particular a nature, as to have no parallel and no similarity with any other cause or object that has ever fallen under our observation. It is only when two species of objects are found to be constantly conjoined, that we can infer the one from the other: and were an effect presented which was entirely singular, and could not be comprehended under any known species, I do not see, that we could form any conjecture or inference at all concerning its cause. If experience and observation and analogy be, indeed, the only guides which we can reasonably follow in inferences of this nature; both the effect and cause must bear a similarity and resemblance to other effects and causes which we know, and which we have found, in many instances, to be conjoined with each other. I leave it to your own reflection to pursue the consequences of this principle." (Ibid.)

The consequences which ought in fairness to be deduced may be stated thus. The effect we contemplate, (i.e. Nature,) is not singular but can be compared with other effects—those of Art. The comparison is made in respect of certain specific attributes or properties upon which the Design analogy turns, so that we may reason upwards to certain specific analogies of Causation. Art manifests the foreseeing attributes of the human artist, and from comparison of these we infer in the Creator like attributes,—what Hume elsewhere calls the natural attributes of the Deity. But this likeness is properly termed analogical, because of the vast difference in the magnitude of the effects from which we thus reason, and of the causes to which we reason. As our wisdom and power are proportionable to our earthly works, so are the Divine wisdom and power proportionable to the whole majestic Universe. There is, then, a comparison in species, but not in grandeur—the attributes are not similar, but analogical. As the Heavens are high above the Earth, so are His thoughts higher than our thoughts.

D.—THE PANTHEISTIC CONSEQUENCES CHARGED UPON PHYSICAL SPECULATIONS.

The following is the passage from Professor Baden Powell referred to in note (h) of the preceding chapter. Some short extracts were also made from it on a previous page.

"Nothing but the common confused and mistaken notions as to laws and causes, could give any colour to the assertion that ... physical speculations tend to substitute general physical laws in the place of the Deity; and that scientific statements of the conclusions of Natural Theology are nothing but ill-disguised Pantheism.

"The utter futility of such inferences is at once seen, when the smallest attention is given to the plain distinctions above laid down between 'moral' and 'physical' causation; and to the proper force of the conclusions from natural science establishing the former by means of the latter.

"This distinction obviously points to the very reverse of the assertion that physical action is identical with its moral cause; the essential difference and contrast between them is the very point which the whole argument upholds and enforces.

"Of all forms of philosophical mysticism, the idea of Pantheism seems to me one of the most extravagant. Ever-present mind is a direct inference from the universal order of nature, or rather only another mode of expressing it. But of the mode of existence of that mind we can infer nothing.

"To assert, then, that this universally manifested mind is co-existent, or even to be identified, with matter, is at best a mere gratuitous hypothesis, and as such wholly unphilosophical in itself, and leading to many preposterous consequences. But if further supposed to apply in any higher sense as to an object of worship, trust, love, obedience, or the like (as is implied in the term Pantheism), it appears to involve moral contradictions of the most startling kind.

"There are, however, many who, though rejecting Pantheism as untrue, do not conceive it absurd or contradictory. Much, however, will, in all such cases, depend on the precise sense in which it is maintained. With some it seems to have been upheld on a fanciful analogy with the conception of the human frame animated by an indwelling spirit; as if in a somewhat similar manner the supreme mind might animate nature. Without disputing this in a certain sense, the cases surely cannot be considered at all parallel: we do not infer the existence of the human mind, from the arrangement and adaptation of the bodily organs, nor is it the moral cause of their organisation.

"If Pantheism were asserted merely in the sense of a kind of vital or animating principle pervading the material world, I would admit that such an idea involves no absurdity, or contradiction, but still I should regard it as visionary and unphilosophical. I could but class it with the 'vital forces' which Kepler fancied necessary for keeping up the motions of the planets, with the 'plastic powers of nature,' 'her abhorrence of a vacuum,' and the like chimæras. But it is when men elevate such a supposed animating principle into a Deity, a being of supreme wisdom, power, beneficence, and goodness, yet residing in every atom of matter, and participating directly in every form and case of material action, that the contradiction arises." Spirit of the Inductive Philosophy, pp. 176-9.

E.—THE EXTENT AND DIVISIONS OF THE SCIENCE OF NATURAL THEOLOGY.

Extract No. 3 acknowledges what all physical investigators ought to acknowledge,—that although their sciences contribute very much towards solving the problem of the Universe, and although their results readily harmonize with the solution maintained by the Theist—yet there rests over that vast problem a cloud which the physical sciences cannot completely dispel. This (as we shall see in Chapter V.) is indeed the confession of the greatest minds at present engaged upon the philosophy of Natural Science.

Extract No. 1.—"From the inductive philosophy we derive our belief in the harmony, order, and uniformity of natural causes, perpetually maintained in a universally connected chain of dependence. And hence it is, that we arrive at those sublime ideas of a presiding Intelligence of which law and uniformity, universal mechanism once for all adjusted, are the proper external manifestations.

"To the truly inductive philosopher, fate and chance, necessity and accident, are words without meaning. To him, the world is made up of recondite combinations of physical laws, and the existence and maintenance of those laws are the very indication of a Supreme Mind. But chance is irreconcilable with laws, fate with mind, regulated and fixed order with blind destiny, fortuitous accident, or arbitrary interruption.

"All rational natural theology advances by tracing the immediate mechanical steps and particular processes in detail, and the physical causes in which the influences of the Great Moral Cause or Supreme Mind are manifested. The greater the number and extent of such secondary steps and intermediate processes through which we can trace it, the greater the complexity and wider the ramifications of the chain of causes, the more powerful and convincing the instruction they convey as to the existence and operation of the Divine wisdom and power.

"Yet it is a common mode of illustration to speak of the chain of secondary causes reaching up to the First Cause. Or, again, fears are entertained of tracing secondary causes too far, so as to intrench on the supremacy of the First Cause. But this is an erroneous analogy: the maker or designer of a chain is no more at one end of it than at the other. The length of the chain in no way alters our conviction of its skilful structure, except to enhance it. If the number of links were truly infinite, so much the more infinite the skill of its framer.

"Mr. F. Newman observes,[69] I think most truly, that the common arguments from what are called 'secondary causes' to the 'First Cause' are unsatisfactory: and I would trace this to the confused sense in which those terms are commonly used, as already explained; and which, I think, might be entirely removed by attention to the distinctions above laid down. While, on the other hand, I fully acknowledge that those arguments, when correctly understood, lead only to a very limited conclusion; and one which falls infinitely short of those high moral and spiritual intuitions on which Mr. F. Newman grounds his religious system, yet in no way discredits or supersedes them." Essay, pp. 151-4.

Extract No. 2.—"In the present state of knowledge, law and order, physical causation and uniformity of action, are the elevated manifestations of Divinity, creation and providence. Interruptions of such order (if for a moment they could be admitted as such) could only produce a sort of temporary concealment of such manifestations, and involve the beautiful light shed over the natural world in a passing cloud. We do not indeed doubt that the sun exists behind the cloud, but we certainly do not see it; still less can we call the obscuration a special proof of its presence. The main point in the system of order and law is its absolute universality. Exceptions, if real, must pro tanto imply a deficiency in the chain of connexion, and might, to a sceptical disposition, offer a ground of doubt.

"But so overwhelming is the mass and body of proof, that no philosophic mind would allow such exceptions for a moment to weigh against it; they would be as dust in the balance. A supreme moral cause manifested through law, order, and physical causes, is the confession of science: conflicting operations, arbitrary interruptions, abrupt discontinuities, are the idols of ignorance, and, if they really prevailed, would so far be to the philosopher only the exponents of chaos and atheism; the obscuration (as far as they extend) of the sensible manifestation of the Supreme Intelligence." Ibid. 165, 6.

Extract No. 3.—"The whole tenor of the preceding argument is directed to show that the inference and assertion of a Supreme Moral Cause, distinct from and above nature, results immediately from the recognition of the eternal and universal maintenance of the order of physical causes, which are its essential external manifestations.

"Of the mode of action or operation by which the Supreme Moral Cause influences the universal order of physical causes, we confess our utter ignorance. But the evidence of such operation, where nature exists, can never be lost or interrupted. And in proportion as our more extended researches exhibit these indications more fully and more gloriously displayed, we cannot but believe that our contemplations are more nearly and truly approaching their Source." Ibid. 179.

The reader will not grudge the time he may have bestowed upon this note if it leads him to a distinct apprehension of the true breadth and compass of our science.

"Natural Theology," says Kant, "infers the attributes and the existence of an author of the world, from the constitution of, the order and unity observable in this world, in which two modes of Causality, together with their laws, must be accepted—that is to say, Nature and Freedom. Thus Natural Theology rises from this world to a supreme Intelligence, whether as to the principle of all natural or of all moral order and perfection. In the former case it is termed Physico-Theology, in the latter Ethical or Moral Theology." This last term he explains by adding, "Not theological ethics; for this latter science contains ethical laws, which presuppose the existence of a Supreme Governor of the world; while Moral Theology, on the contrary, is an evidence of the existence of a Supreme Being, an evidence founded upon ethical laws." Kant's Kritik der reinen Vernunft Transscendental Elementarlehre, s. 7.

It was from the fulness and depth of a personal conviction on this topic that the present writer ventured to assert in 1870 that "The conditions under which Natural Theology becomes scientifically possible, are found when it supplements Natural Science by a science of Right and Wrong," and also that "for the future Natural Theology ought to follow this path and no other—unless it wishes to commit suicide." These assertions were made in a University Sermon[70] on the question, "Under what Conditions is a Science of Natural Theology possible?" and they were censured as novel and unprecedented by critics who ought to have known better.

F.—ON TELEOLOGY.

Let it be observed that such a collection of opinions implies no appeal to authority in the narrow sense of the word. There is indeed a manifest distinction between authority and authorities—and our present appeal is to the latter. No man's ipse dixit can dogmatically settle questions which belong to an inquirer's responsible self; but it is surely the wisdom of every one who acknowledges the awful sense of accountability attendant on the determination of questions affecting his central beliefs, to weigh the reasonings of others who have felt the same deep impression of their paramount importance. If any one is reluctant so to do from an idea that by doing thus much he pays a wrongful deference to prejudices, he has in truth assumed the whole issue which he is bound to examine. How otherwise can he certainly allege that the prejudice is not inherent within himself?

Reluctance of this kind would on the present occasion be thoroughly misplaced. Authorities as here quoted are neither more nor less than the opinions of experts who have a title to be heard each in his own proper department. Throughout the practical conduct of life we all experience the benefit of laying aside our private spectacles from time to time and of looking through the glasses of other men. And in questions such as the one now before us, is it possible to do better than try whether we can see for ourselves what has been pronounced discernible by men who contemplated this world of ours with more than ordinary powers of vision?

The present writer has a personal interest in bringing together the reflections of many who have reached the same resting-place along various lines of approach, and who have expressed their conclusions with some diversity of language. He has ventured himself on viewing the evidences of Natural Theology from a position by no means identical with that most commonly occupied by Natural Theologians. The student, therefore, who takes a wide survey of the field will be the critic best prepared to examine the latter part of this Essay.

The first authority quoted among our ample citations is Hume, whose appearance as a witness for Natural Theology may surprise some readers. As, however, is remarked by an eminent writer in the Quarterly, Hume's hard common sense "enabled him when he liked, to control the excesses of a speculative imagination and subject it to practical reason, as he understood reason's verdict." He even went so far as to say that "The whole frame of Nature bespeaks an Intelligent Author; and no rational inquirer can, after serious reflection, suspend his belief a moment with regard to the primary principles of genuine Theism and Religion." (Natural History of Religion, Introduction.) Indeed, according to Cucheval Clarigny,[71] Hume was an "almost Christian" at certain periods of his life. The repellant forces that kept him back, are "not far to seek."

The following passages refer to the illative analogy which forms the proper shape of the argument from Design.

"That the works of Nature bear a great analogy to the productions of art, is evident; and according to all the rules of good reasoning, we ought to infer, if we argue at all concerning them, that their causes have a proportional analogy. But as there are also considerable differences, we have reason to suppose a proportional difference in the causes; and in particular ought to attribute a much higher degree of power and energy to the supreme cause than any we have ever observed in mankind. Here then the existence of a DEITY is plainly ascertained by reason: and if we make it a question whether, on account of these analogies, we can properly call him a mind or intelligence, notwithstanding the vast difference which may reasonably be supposed between him and human minds; what is this but a mere verbal controversy? No man can deny the analogies between the effects: To restrain ourselves from inquiring concerning the causes, is scarcely possible: From this inquiry, the legitimate conclusion is, that the causes have also an analogy: And if we are not contented with calling the first and supreme cause a GOD or DEITY, but desire to vary the expression; what can we call him but MIND or THOUGHT, to which he is justly supposed to bear a considerable resemblance?" Dialogues concerning Natural Religion, Part xii. in Essays, Vol. II. p. 526.[72]

"If the whole of Natural Theology, as some people seem to maintain, resolves itself into one simple, though somewhat ambiguous, at least undefined proposition, That the cause or causes of order in the universe probably bear some remote analogy to human intelligence. If this proposition be not capable of extension, variation, or more particular explication; if it affords no inference that affects human life, or can be the source of any action or forbearance; and if the analogy, imperfect as it is, can be carried no farther than to the human intelligence, and cannot be transferred, with any appearance of probability, to the other qualities of the mind: If this really be the case, what can the most inquisitive, contemplative, and religious man do more than give a plain, philosophical assent to the proposition, as often as it occurs; and believe that the arguments on which it is established, exceed the objections which lie against it?" Ibid. p. 538.

The following is the opinion of Cleanthes, upon whom Hume confers the palm in the dialogue;—"Take care, Philo, replied Cleanthes; take care; push not matters too far: allow not your zeal against false religion to undermine your veneration for the true. Forfeit not this principle, the chief, the only great comfort in life; and our principal support amidst all the attacks of adverse fortune. The most agreeable reflection, which it is possible for human imagination to suggest, is that of genuine Theism, which represents us as the workmanship of a Being perfectly good, wise, and powerful; who created us for happiness; and who, having implanted in us immeasurable desires of good, will prolong our existence to all eternity, and will transfer us into an infinite variety of scenes, in order to satisfy those desires, and render our felicity complete and durable. Next to such a Being himself (if the comparison be allowed), the happiest lot which we can imagine, is that of being under his guardianship and protection." Ibid. p.535.[73]

The next three extracts give Hume's opinion on the prevailing principle disclosed by the analogy—design, purpose, and the recognition of final causes:—

"Though the stupidity of men, barbarous and uninstructed, be so great, that they may not see a sovereign author in the more obvious works of nature, to which they are so much familiarized; yet it scarce seems possible, that any one of good understanding should reject that idea, when once it is suggested to him. A purpose, an intention, a design is evident in everything; and when our comprehension is so far enlarged as to contemplate the first rise of this visible system, we must adopt, with the strongest conviction, the idea of some intelligent cause or author. The uniform maxims, too, which prevail throughout the whole frame of the universe, naturally, if not necessarily, lead us to conceive this intelligence as single and undivided, where the prejudices of education oppose not so reasonable a theory. Even the contrarieties of nature, by discovering themselves everywhere, become proofs of some consistent plan, and establish one single purpose or intention, however inexplicable and incomprehensible."
