ОглавлениеPHILOSOPHY OF DESIGN.
"It is an assured truth, and a conclusion of experience, that a little or superficial knowledge of Philosophy may incline the mind of Man to Atheism, but a farther proceeding therein doth bring the mind back again to Religion: for in the entrance of Philosophy, when the second causes, which are next unto the senses, do offer themselves to the mind of man, if it dwell and stay there it may induce some oblivion of the highest Cause; but when a man passeth on farther, and seeth the dependence of causes and the works of Providence; then, according to the allegory of the poets, he will easily believe that the highest link of Nature's chain must needs be tied to the foot of Jupiter's chair."
Lord Bacon's Advancement of Learning, Book I.

CHAPTER II.
PHILOSOPHY OF DESIGN.
The argument from Design in Nature has been made familiar to most readers in Natural Theology by Paley's well-known book. It is probable that no argument has ever been more praised, and at the same time more strongly controverted. Our business lies, of course, with the controversy; and we must say a few words on our present mode of dealing with it.
Nothing could be more useless than to repeat illustrative examples of Design already thrice told by an endless variety of treatises. Of so wide a subject everything may be quoted as an illustration, from a pebble to a world, if only the principle illustrated—the pivot on which the argument turns—be understood and admitted. In modern times, this turning-point is precisely the centre of the dispute. Untrained minds misapprehend the meaning of the word Design, and are further still from apprehending the real force of argument from analogy. And when these subjects come to be discussed by skilled writers, various questions are always raised which generally issue in irreconcilable differences of opinion.
Our plan here will be to take the argument in its best-known shape, and examine it from the points of view occupied by several classes of objectors, beginning, as is reasonable, with the most popular difficulties and misapprehensions. It does not seem necessary to load the page with references to controversialists of the ordinary sort, particularly as we endeavour to look at the whole question through their eyes.
Respecting the more philosophic questions it is necessary to observe, that the Evolution-theory will not form a topic of the present chapter. It is excluded for two reasons. One, that we are now trying to put a value on the argument from Design per se, and not to compare it with rival theories. The other reason springs from the subject of Evolution itself—it is too extensive to be thus briefly treated—and the sum of this Essay must be taken together as furnishing a counter statement to the manner in which it has been employed by certain of its ardent advocates.[14]
We hope for a further advantage from the method proposed. The cause of truth ought to gain from being looked at on more than one side; and, whatever be the worth and true effect of reasoning from Design, we may expect by this method to display it adequately.
The word itself, like all figurative terms—or words used in a secondary sense—is by no means free from ambiguity. It has, in common parlance, several shades of signification. Design being the centre of Paley's argument, and containing the one idea which gives force to all the rest: his first object was to fix the sense in which he employed it. He did so by using an illustration.
To explain by comparison is always a popular resource, some serious drawbacks notwithstanding. Almost every one prefers that an author should use a sparkling similitude which tells a great deal, rather than write what looks like a grammar and dictionary of his science. Analysis and induction require thought on the part of him who employs them—thought also on the part of a reader determined to understand what he reads. Paley saw all this thoroughly, and at the beginning of his book employed the now celebrated comparison taken from a watchmaker and a watch. His judgment received support from the popularity he enjoyed, and from the way in which everybody borrowed his illustration.[15]
Yet Paley's deference to the popular understanding gave rise to the first general misapprehension of his treatise. He sets out from a kind of surprise—the surprise his readers would feel at finding a watch upon a heath. Now this feeling was immediately alleged as a conclusive objection against Paley's comparison, and as a ground for distrusting the whole argument founded upon it. The world, it was said, cannot be likened to a watch, nor yet to any other sort of mechanism. Between things natural, and the things which men make, the difference is not a mere contrast of perfection with imperfection. The real reason why we are surprised to see Paley's watch lying on a moor—and not at all surprised to see Paley's stone lying beside it—springs from this very difference. And though the history of a stone, common, coarse, and worthless, is really more wonderful than the history of any watch, and though the stone has an infinitely longer pedigree, we should never speak or think of it in the same way. We feel that the objects are dissimilar, and our surprise testifies the fact. A heath is given up to nature, a watchmaker's shop to art. The watch is out of place among stones, the stone among watches. The idea raised at the outset, therefore, is that Art and Nature would seem to be thoroughly unlike.
At a first view of the subject, these remarks appear open to one obvious rejoinder. The sort of surprised feeling which Paley describes, is not in itself a proof of real unlikeness. A weed is a plant out of place; we do not expect thriving crops of cabbage or teazle in a carefully kept rose-garden, nor gooseberry bushes amongst azaleas. The proudest flower that blossoms is a weed in a vineyard, in a plot of opium-poppies, or mixed with other herbs medicinal. So, too, a rough diamond would not be out of place in a watchmaker's shop; but if we saw a stone of no selling value inside a case of watches we should certainly experience some surprise. And the feeling would remain even though we were quite unable to explain how the poor pebble differed chemically from the priceless gem. We know that the latter would appear to a jeweller's customers like a rose among flowers, but the former worthless as a weed. The jeweller would consider it a trespasser fit only to be turned out of doors.
But does this rejoinder satisfactorily dispose of the difficulty? Is not the true reason why we might observe with some wonder a watch lying upon a moor resolvable into the fact of our knowing its use and being quite sure that some one had dropped it there?[k] A savage might not feel in the least surprised, unless, indeed, he happened to suppose that the watch was a kind of animal he had never seen before, and took notice of the singular sound it made. In this event he would probably break it to pieces without discovering the purpose or mode of its contrivance.
Throughout all disputatious matter, a thought on one side leads to a thought upon the other—at least, amongst tolerably fair people. The idea which we have just imagined our savage to entertain respecting a watch suggests a further question. What effect ought in reason to be produced upon cultured minds by the contemplation of some unknown or half-comprehended phenomenon?—a question this, closely bearing upon the whole subject under discussion. Now surely it is from intelligent wonder—a contrast of the unknown with what we already know—a feeling of mystery to be solved by us, that inquiry and science perpetually spring. A fossil-shell, the former habitation of a marine animal, found upon some mountain top, presents a contrast and a mystery of this kind. Moreover, the highest triumph of inquiring science is the discovery, not of difference anywhere, but rather of resemblances in objects apparently diverse. An uninquiring mind will never perceive any common attribute, either ideal or structural, between a stone and a watch.
But did Paley himself perceive any such community of attribute? So far does he appear from the perception that he speaks of the stone as an "unorganised, unmechanised substance, without mark or indication of contrivance," and adds, "It might be difficult to show that such substance could not have existed from eternity." Paley's day was meagre in natural science, and Paley was as meagrely acquainted with its results as he was with metaphysical philosophy. Few people, however, even now-a-days, know enough of the laws which govern inorganic products to find their investigation a slight or easy task. For a purpose of comparison with any human work or mechanism, most inquirers will prefer having recourse with Paley to the world of organisation. The flower and fructification of a plant or shrub growing on the heath beside Paley's watch, though carelessly passed over a thousand times, and exciting no surprise from anything unusual in its habitat, will, when observed, raise the most sincere admiration. And the same may be said of the bony skeleton of the lizard[16] racing round plant and shrub, the forehand of the mole which burrows beneath them, and the wing of the bat circling nightly in upper air.
Take, then, replies the objector, an organism, vegetable or animal, whichever you or Paley may prefer. The difficulty formerly urged at once recurs, slightly altered in shape, but with augmented point and force. Your organisms are not put together like the parts of a watch (undique collatis membris)—brass from this place, steel from that, and so on, with china dial-plate, covering-glass, and gold case. All these things were apart in nature, they were severally chosen, manipulated, and brought together. What we see is a successful union of materials possessing inherent adaptation to definite purposes—such as the freedom of brass from rust, or the superior elasticity of steel, qualities indicating the skill and workmanlike knowledge of some human artificer, and showing by their utilization the truth of what was before asserted. Watches and worlds, the products of Art and of Nature, are obviously and thoroughly unlike.
By way of answer, it might be observed that in organization we do really see very distinct constituents combined. In a plant, for instance, there is the combination of a growing point, a humus or pabulum that feeds it, and the stimuli, air, water, light, and all the "skiey influences" by which its passive vitality is excited and sustained. We see plant life, by reason of these concurrent adaptations, swelling into leaf, stem, bud, corolla, and fruit, throughout all the brighter tribes of vegetable beauty that bloom apparent to the unassisted eye. And the like holds true respecting animals, but with increased variety and complication of conditions, made necessary by their higher mode of existence. The marvels of their many powers, habits, and perfections of form and movement are great, but greater still the vast multitude of ministering aids put in requisition to ensure their earliest appearance and after continuance in life and enjoyment. When we contemplate microscopic Nature, a like sweep of combination is again evident to the skilful naturalist, and excites his constant wonder, especially when observed in connection with the exquisite finish of minute creatures and their infinitesimal parts, both alike unperceived by our ordinary human senses. And a similar idea of invisible, and perhaps almost incomprehensible, harmony might be raised by a consideration of the elements, metallic and non-metallic, brought together in numberless inorganic productions, as well as of the forces which bind them in hard cohesion, and give them such properties as we may discover in the commonest block of granite. And what if we could extend our field of view to a world—to the universe?
The answer suggested by this last paragraph has its value, and the principle involved in it will occur for our scrutiny further on. But at present this train of thought, if pursued, might be likened to the weed we spoke of,—it would not be altogether in place here. The truth is that the whole objection thus parried appears more out of place still, and is therefore itself not a flower, but a weed of popular rhetoric. And the reason of its irrelevancy is plain. Paley's argument does not really turn upon the similitude of any two objects of simple apprehension, but upon an analogical comparison; the discovery, that is, of the likeness between two ratios, a process known in common life under the name of Proportion. Hence it is from the illative force of analogy that this topic of Design derives its value. The analogy does, in fact, serve a double purpose,—- first to explain, and secondly to prove. We had better look at it from both points of view.
The easiest method for making an illustrative analogy intelligible is to state it in old-fashioned style as a rule of three sum; the fourth term being the conclusion which completes it. "As a watch is to the watchmaker, so is creation, (exemplified by such and such a specimen,) to its Creator." That is to say, there exists some ratio or relation connecting the watch and the watchmaker, which exists also between the world and its Creator.
To see its illative force used as an argument, we need only alter the position of the four terms, and state our proportion as is more usual in modern day. "As the watch is to such and such specimens of creation, so is the watchmaker to the Author of any and all of these things."
In the first statement Paley's similitude is displayed in full as an asserted illustration of Design. The watch is a thing contrived—that is, a design realized, and the maker is its contriver. Just so, is the world a Design realized by its Creator. And it appears plainly implied in the assertion, that even as the little watch shows the limited power and intelligence of its maker, so the vast and unfathomable universe illustrates the infinite power and wisdom of its incomprehensible Author.
The second mode of statement displays the force of Paley's analogy viewed as a chain of reasoning. The watch is not like the world, but there is something in common between them, and this something it is Paley's purpose, and the purpose of his various continuators, to show at the greatest convenient length. Now such community of character must be sufficient to establish a further community still. When we see a watch we are sure it had a designer,—the watchmaker; and here, again, Paley means to argue that from every example of contrivance which we can adduce and examine, the same inference ensues, and always must ensue. Therefore (he concludes) from the immeasurable designed world we infer the world's omnipotent Designer.
The chief Divine attributes (as, for example, omnipotence) are dwelt upon by Paley towards the close of his treatise. But it seems well to insert the adjective at once. Most thinking persons admit that whoever believes in a Creator may find from the physical Cosmos and its
"Mysterious worlds untravelled by the sun,"
ample reason for justifying the noblest of such adjectives. They generally go further, and allow that any Theist finds in these endless marvels a full confirmation of his faith—there is, as Coleridge says, a whole universe at hand to ratify the decision. But what many educated people who concede thus much disallow, is the sufficient witness of Design standing by itself to prove what it may fairly corroborate or even extend. To illustrate, confirm, or widen what is already held a truth is one thing; to serve as its sole sufficient witness is another. This conclusiveness some deny, and more scruple to affirm. And one of the drawbacks in arguing from analogy seems to be, that all except the most philosophically trained minds experience a sort of hesitation in estimating its force—a hesitation which they are at a loss to define in words. Consequently, the attack upon its adequacy is always difficult to answer; so many various shades of negation must be classed together for brevity's sake, and met by one or two general lines of defence. The safest way, probably, is to make the negative classes as wide as possible, and to put the scientific doubts in their most fatal form of expression. And it appears hard to imagine anything really destructive of evidence which may not be brought under one of the two following heads. There may be, first, a failure of evidence when it is not strong enough in its facts and circumstances to justify the conclusion drawn—when, in short, it proves too little. Secondly, it is worthless, if its acceptance so damages the position occupied by those who employ it, that their purpose is thereby destroyed, their locus standi demolished—in other words, they have proved too much.
May we not, then, presume it impossible to bring worse charges against any argument than whatever can be urged in support of these two accusations? And we will first put the well-known analogy on its trial for proving too much, because it is from anxiety to avoid this charge that most analogical reasoners are apt to risk proving too little.
Admit, say Paley's most decided antagonists, the relevancy of an argument from human art. It must be taken to show the Creator of the Universe as Theists conceive and acknowledge Him. Let us at once ask in what light He is thereby represented? Is it not, so to speak, as a supreme Anthropomorphic[l] Craftsman sketching a vast plan or design, and moulding the materials necessary for its realization? We begin with the remark that His work—the world—must show some traces of that plastic process and the hand of its Moulder. The requirement seems just and reasonable, and is commonly answered by an appeal to what have been termed the records of creation, the structure of the heavens, and the structure of the earth. Thus, for example, we are referred to Geology and Palæontology, and are led from age to age, and type to type. In passing from one formation to another we seem (as Goethe said) to catch Nature in the fact. At all events the plastic process is everywhere traceable, and to its evidences the Theist points with triumph.
But no intelligent objector can stop here. He will next inquire what on theistic principles was the origin of this material substance so constantly undergoing transformation. Most sceptical thinkers put the inquiry in a trenchant manner; they not only demand to be answered, but they prescribe beforehand the sort of answer to be returned. It is useless, they tell us, to speak of archetypes existing in the Divine mind, and to illustrate them by the creative thought of musician or sculptor, of painter or of poet. The hard, coarse world must be looked at as it is: an actual material habitation for sorrowing and sinful human creatures; its physical conditions, imperfect in that respect, unhappily corresponding too well with the low moralities of its tenants.
Now, they say, if we examine Paley's common-sense analogy no one can at all doubt what answer is suggested there. The steel of the watch-spring, the brass of the wheel-work, and other materials for all the curious mechanical contrivances required, were taken into account by the watch-designer when he formed his design. Had it been otherwise he could not have calculated on finding the necessary strength, elasticity, resistance to rust, and other properties on which Paley dwells so distinctly. In like manner, it has been said by some physical science Christians since Paley's time: "Let matter and its primary properties be presupposed, and the argument from Design is easy." True, but it seems quite as easy to suppose the world itself eternal. And we know that this supposition was adopted by pagan philosophers, to whom it appeared the easiest of all beliefs.
But other philosophic pagans, holding clearly that the world had a beginning, conceived its First Cause to be like Paley's Designer—analogous to an earthly workman. They carried out the analogy thoroughly—more thoroughly than modern writers, and believed both Artificer and the matter from which He shaped the visible universe, self-subsistent, indestructible, and co-eternal.
In this eternity of matter and its native inflexibilities, these great heathen thinkers found an apology for what they considered the failure of creative power—misshapen things, monstrosities, and imperfections. The Creator never desired them, but His will was thwarted by the material He worked in. Against this dualism the early Fathers protested. Will the modern Theist (his assailants ask) deny himself, and affirm two independent and self-existent principles; or will he deny the parallelism asserted in Paley's analogy? Can he conscientiously believe that its issue is a worthy representation of the Divine and omnipotent Creator? If not, it has failed by proving too much[m]. raised. Who can help seeing that several of them lie equally against all rational theories which have ever been suggested to account for the origin of that sorrow and evil which we see and acknowledge everywhere? And does not the same remark apply to every attempt at solving the antithesis of mind and matter? Some thoughtful men have believed that they could see their way to a solution; others believe it altogether above human reason, and point with a kind of triumph to the failures of philosophy. However this may be, the mournful moral enigma,[17] and the unexplained antithesis underlying our knowledge of nature, attach themselves equally to every possible conception of the universe, religious or irreligious, common-sense or metaphysical. They have no special connection with our argument from Design, and ought not in fairness to be brought as objections against it.
The more real question just now is, whether Paley's mechanical analogy was to blame for introducing the problem of cosmical matter into the discussion.
On this question the opinions of competent and unprejudiced judges disagree. By an eminent and accomplished writer the case is summed up as follows, in the Harveian Oration for 1865. Having previously included the material factor under mechanical adaptation as distinguished from art in the highest sense, Dr. Acland goes on to say (page 13): "The illustration of the watch so quaintly employed by Nieuwentyt, and so entirely appropriated by Paley, only in a coarse way suggests the parallel between infinite art and common mechanical skill. It has done some mischief to the cause it advocates, by making familiar a rude illustration, which minds without imagination, or void of constructive power, have accepted as a recognised explanation of the method of operation by an Infinite Creative Will."
Paley's critics should however observe, that he did not himself intend the objectionable inference. Probably he never even perceived that it might be drawn from his comparison. Abstract inquiries connected with Theism, he banished to the end of his book, where they are discussed in a manner little calculated to satisfy any readers who have ever felt them as substantial difficulties.[18] But then, he would most likely have referred these persons to the writings of professed metaphysicians. It may be wise for us to take warning both by what Paley did and by what he left undone. Some deeper questions are indispensable to the argument from Design, but we shall follow his example so far as to avoid such disquisitions as were current in his day under the name of metaphysics. On the other hand we shall draw the required data from that critical Fact-philosophy of Mind and Human Nature, which forms to so many thinkers the birth-star of a new science, one amongst the rising hopes of our nineteenth century.
Meantime, our business on hand is to rebut the present accusation of proving too much, brought against Paley's analogy. We shall try to complete our answer by setting his argument in the point of view under which he evidently meant it to be looked at.
Either as an illustration or as a means of proof, Analogy need not hold in more than a single point; provided only that this single point is clear and well-established—resting, for example, on a moral law or a causal nexus. Any one who desires to make an analytical investigation into this law of inference will receive valuable aid from Ueberweg's Logic, §§ 131 and 2, particularly if compared with § 129.
To a common-sense mind we may give sufficient satisfaction by adducing one or two good analogies. Thus, for instance, the duties of a religious minister are often explained by saying that he ought to be the shepherd of his flock; that is, his relation to his people ought to resemble that of the shepherd to his sheep. We all understand how truly is here expressed a world of watchful care. But are all points of the relation to be implied? May the spiritual pastor ever become the slayer or the salesman of his flock?
Again,—writers upon political subjects some years ago used very commonly to quote from the days of Alfred the Great supposed precedents for our most modern constitutional dicta. In many cases the thing defended was a legitimate outgrowth of the precedent cited; but to pronounce the two identical seemed sufficiently absurd. In confutation of some such absurdities, clever men argued that the body corporate has, like the individual body, its childhood, growth, and maturity. The argument became generally accepted, and got extended to the distinctions between healthy increase and sickly degeneration, with other like inferences. The further conclusion was next drawn, that every national body resembles the human frame in a necessary decay, and inevitable mortality. Now, whatever opinion may be entertained as to the fact of a death-rate of nationalities, nothing seems more certain than that those who first employed the comparison never contemplated this particular corollary. Whether their first use of it was wise or unwise, has been, like Paley's Watch-analogy, a matter of some considerable dispute.
The general subject of Analogy, rightly or wrongly extended, admits of wider illustration.
Simile and metaphor are often compressed analogies, and many of them gain in beauty from expansion. Pope's celebrated comparison of the traveller ascending the Alps with the student who scales the heights of literature; and how
