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.
