Part 14

It is not my present intention to call in question either of these varieties of evolution. Inadequate as the evidence of them both appears to be, I will suppose their case to be made out: and still, I submit, it does not justify the sceptical estimate which it habitually fosters of the intellectual, moral, and religious intuitions of the human mind. For,

(1) Though animal sensation, with its connected instinct, should be the raw material of our whole mental history, it is not on that account entitled _to measure all that comes after it_, and stand as the boundary-line between fact and dream, between terra firma and "airy nothing." That which is first in Time has no necessary priority of rank in the scale of truth and reality; and the later-found may well be the greater existence and the more assured. If it is a development of Faculty, and not of incapacity, which the theory provides, the process must advance us into new light, and not withdraw us from clearer light behind: and we have reason to confide in the freshest gleams and inmost visions of to-day, and to discard whatever quenches and confuses them in the vague and turbid beginnings of the Past. With what plea will you exhort me, "If you would rid yourself of intellectual mysteries, come with us, and see the stuff your thought is made of: if you would stand free of ideal illusions, count with us the medullary waves that have run together into the flood-tide of what you call your conscience: if you would shake off superstition, look at the way in which the image of dead men will hang about the fancy of a savage, or the personification of an abstract quality imposes on the ignorance of simple times"? Is our wisdom to be gathered by going back to the age before our errors? And instead of consulting the maturity of thought, are we to peer into its cradle and seek oracles in its infant cries? If the last appeal be to the animal elements of experience, we can learn only by unlearning; and by shutting one after another of the hundred ideal eyes of the finished intellect, we shall have a chance of seeing and feeling things as they are. If nothing is to be deemed true but what the pre-human apes saw, then all the sciences must be illusory; with the suicidal result that, with them, this doctrine of Evolution must vanish too. Or if, stopping short of this extreme distrust of the acquired intuitions, you make a reservation in favor of the new visions of the intellect, what right can you show for discharging those of the conscience? The tacit assumption therefore that you upset a super-sensual belief, by tracing the history of its emergence among sensible conditions, is a groundless prejudice.

(2) Further, the question to be determined may be presented as a problem in physiology, to be resolved by corresponding rules: What is the _function_ of certain parts of our human constitution, viz., the Reason and the Moral Faculty? Now it is a recognized principle that, in estimating function, you must study the organ, not in its rudimentary condition, before it has disengaged itself from adjacent admixtures and flung off the foreign elements, but in its perfect or differentiated state, so as to do its own work and nothing else. In order to give the idea of a timepiece to one who had it not, you would not send him to one of the curious mediæval clocks which could play a tune, and fire a gun, and announce the sunrise, and mark the tides, and report twenty miscellaneous things besides; but to the modern chronometer, simple and complete, that, telling only the moment, tells it perfectly. And in natural organizations, to learn the capabilities and project of any structure, you would not resort to the embryo where it is forming but not working: you would wait till it was born into the full presence of the elements with which it had to deal; not till then could you see how they played upon it, and what was its response to them. In conformity with this rule, whither would you betake yourself, if you want to measure the intrinsic competency of our intellectual faculty, and determine what its very nature gives it to know? Would you take counsel of the nurse who held you "when you first opened your eyes to the light,"[10] or otherwise study "the first consciousness in any infant," "before the time when memory commences,"[11] and disregard every thing "subsequent to the first beginnings of intellectual life"?[12] On the contrary, you would avoid that soft inchoate promise of nature, only nominally born, where the very structures of its finer work have not yet set into their distinctive consistency and form; and will hold your peace till the faculty is awake and on its feet, and can clearly tell you what it sees for itself, and what it makes out at second-hand: just as, to gauge the lunar light, you must have patience while the thin crescent grows, and wait till the full orb is there. Still less can you take the report of the Moral Faculty from the confessions of the cradle, or from the quarrels and affections of the apes; the conditions being not yet present for the bare conception of a moral problem. The most that can be asked of an intuition is, that it shall keep pace with the cases as they arise, and be on the spot when it is wanted; and if you would know what provision our nature holds for dealing with its Duty and interpreting its guilt, you must go into the thick of its moral life, and bid it tell you what it sees from the swaying tides of temptation and of victory. The "purity" of intuitions is not "pristine," but ultimate; cleared at length from accidental and irrelevant dilutions, and with essence definitely crystallized, they realize and exhibit the idea that lay at the heart of all their tentatives, and constitutes their truth. Am I told that it is hopeless at so late an hour to separate what is an indigenous gift from what is implanted by education? I reply, it no doubt requires, but it will not baffle, the hand of skilled analysis; it is a difficulty which, in other cases, we find it not impossible to overcome; for there are assuredly instincts and affections, strictly original and natural, that make no sign and play no part till our maturer years, yet which are readily distinguished from the products of artificial culture.

[Footnote 12: Ibid., p. 160.]

If, to find the functions of our higher faculties, we must look to their last stage, and not to their first, we at once recover and justify the ideal conceptions which the expositors of Evolution are accustomed to disparage as romance. For among these functions are present certain Intuitive beliefs--for the Reason, in Divine Causality; for the Conscience, in Divine Authority; together blending into the knowledge of a Supreme and Holy Mind. These august apprehensions we are entitled to declare are not the illusions, but the discoveries, of Man; who, by rising into them, is born into more of the Universe of things than any other being upon earth, and is made conscious of its transcendent and ultimate realities. If these trusts are indeed the growth of ages, from seeds invisibly dropped upon the field of time, be it so; it was not without hand: there was _a Sower_ that went forth to sow.

II. We turn now to the Second Form of doubt raised by the doctrine of Evolution: under which it weakens our objective trust in an originating Mind.

A naturalist who to his own satisfaction has traced the pedigree of the human intellect, conscience, and religion, to Ascidian skin-bags sticking to the sea-side rocks, is not likely to arrest the genealogy there, at a stage so little fitted to serve as a starting-point of derivative being. Or, if his own retreat should go no further, others will take up the regressive race, and, soon passing the near and easy line into the vegetable kingdom, will work through its provinces to its lichen-spotted edge: and, after perhaps one shrinking look, will dare the leap into the dead realm beyond, and bring home the parentage of all to the primitive elements of "matter and force." To give effect to this extension over the universe at large of the theory of Evolution, the scientific imagination of our day has long been meditating its projected book of Genesis, and has already thrown out its special chapters here and there; and though the scenes of the drama as a whole are not yet arranged, the general plan is clear: that the Lucretian method is the true one; that nothing arises for a purpose, but only from a power; that no Divine Actor therefore is required, but only atoms extended, resisting, shaped, with spheres of mutual attraction and repulsion; that, with these _minima_ to begin with, a growth will follow of itself by which the _maxima_ will be reached; and that thus far the chief and latest thing it has done is the apparition of Mind in the human race and civilization in human society, conferring upon man the melancholy privilege of being, so far as he knows, at the summit of the universe.

The main support of this doctrine is found in two arguments, supplied respectively by physical science and by natural history; each of which we will pass under review.

i. The former relies on the new scientific conception of the _Unity of Force_. When Newton established the composition of Light in his treatise on Optics, and the law of Gravitation in his Principia, he conceived himself to be treating of two separate powers of nature, between which, quick as he was to seize unexpected relations, he dreamt of no interchange. Yet now it is understood that when collisions occur of bodies gravitating on opposite lines, the momenta that seem to be killed simply burst into light and heat. When Priestley's experiments detected the most important chemical element on the one hand, and the fundamental electrical laws on the other, he seemed to move on paths of research that had no contact. Yet, in the next generation, chemical compounds were resolved by electricity; which again turns up in exchange for magnetism, and can pass into motion, heat, and light. To see the transmigration of natural agency, trace only through a few of its links the effect of the sunshine on the tropic seas. So far as it warms the mass of waters, either directly or through the scorched shores that they wash, it stirs them into shifting layers and currents, and creates _mechanical_ power. But it also removes the superficial film; and thus far spends itself, not in raising the temperature, but in changing the form from liquid to vapor, and so altering the specific gravity as to transfer what was on the deep to the level of the mountain-tops. It is the Pacific that climbs and crowns the Andes, resuming on the way the liquid state in the shape of clouds, and as it settles crystallizing into solid snow and ice. The original set of solar rays have now played their part, and made their escape elsewhere. But there is sunshine among the glaciers too, which soon begins to resolve the knot that has been tied, and restore what has been stolen. It sets free the waters that have been locked up, and lets their gravitation have its play upon their flow. As they dash through ravines, or linger in the plains, they steal into the roots of grass and tree, and by the tribute which they leave pass into the new shape of _vital_ force. And if they pass the homesteads of industry, and raise the food of a civilized people, who can deny that they contribute not only to the organic, but to the _mental_ life, and so have run the whole circuit from the lowest to the highest phase of power? That the return back may be traced from the highest to the lowest, is shown by every effort of thought and will; which through the medium of nervous energy in one direction sets in action the levers of the limbs, and in another works the laboratory of the organic life, and forms new chemical compounds, of which some are reserved for use, while others pass into the air as waste. Still further: all doubt of identity in the force which masks itself in these various shapes is said to be removed by the test of direct measurement before and after the change. The heating of a pound of water by one degree has its exact mechanical equivalent;[13] and a given store of elevated temperature will overcome the same weights, whether applied directly to lift them, or turned first into a thermo-electric current, so as to perform its task by deputy.[14] The inference drawn from the phenomena of which these are samples is no less than this: that each kind of force is convertible into any other, and undergoes neither gain nor loss upon the way; so that the sum-total remains for ever the same, and is only differently represented as the proportions change amongst the different forms of life, and between the organic and the inorganic realms. Hence arises the argument that, in having _any_ force, you have virtually _all_; and that, assuming only material atoms as depositories of mechanical resistance and momentum, you can supply a universe with an exhaustive cosmogony, and dispense with the presence of Mind, except as one of its phenomena.

[Footnote 14: See Grove's Correlation, p. 255, 5th ed.]

To test this argument, let us grant the data which are demanded, and imagine the primordial space charged with matter, in molecules or in masses, in motion or rest, as you may prefer. Put it under the law of gravitation, and invest it with what varieties you please of density and form. Thus constituted, it perfectly fulfils all the conditions you have asked; it presses, it moves, it propagates and distributes impulse, is liable to acceleration and retardation, and exhibits all the phenomena with which any treatise on Mechanics can properly deal. In order, however, to keep the problem clear within its limits, let us have it in the simplest form, and conceive the atoms to be all of _gold_; then, I would fain learn by what step the hypothesis proposes to effect its passage to the _chemical_ forces and their innumerable results. _Heat_ it may manage to reach by the friction and compression of the materials at its disposal; and its metal universe may thus have its solid, liquid, and gaseous provinces; but, beyond these varieties, its homogeneous particles cannot advance the history one hair's breadth through an eternity. It is not true, then, that the conditions which give the first type of force suffice to promote it to the second; and in order to start the world on its chemical career, you must enlarge its capital and present it with an outfit of _heterogeneous_ constituents. Try, therefore, the effect of such a gift; fling into the pre-existing caldron the whole list of recognized elementary substances, and give leave to their affinities to work: we immediately gain an immense accession to our materials for the architecture and resources for the changes of the world,--the water and the air, the salts of the ocean, and the earthy or rocky compounds that compose the crust of the globe, and the variable states of magnetism and heat, which throw the combinations into slow though constant change. But with all your enlargement of data, turn them as you will, at the end of every passage which they explore, the _door of life_ is closed against them still; and though more than once it has been proclaimed that a way has been found through, it has proved that the living thing was on the wrong side to begin with. It is not true, therefore, that, from the two earlier stages of force, the ascent can be made to the vital level; the ethereal fire yet remains in Heaven; and philosophy has not stretched forth the Promethean arm that can bring it down. And if, once more, we make you a present of this third phase of power, and place at your disposal all that is contained beneath and within the flora of the world, still your problem is no easier than before; you cannot take a single step towards the deduction of sensation and thought: neither at the upper limit do the highest plants (the exogens) transcend themselves and overbalance into animal existence; nor at the lower, grope as you may among the sea-weeds and sponges, can you persuade the sporules of the one to develop into the other. It is again not true, therefore, that, in virtue of the convertibility of force, the possession of any is the possession of the whole: we give you all the forms but one; and that one looks calmly down on your busy evolutions, and remains inaccessible. Is, then, the transmigration of forces altogether an illusion? By no means; but before one can exchange with another, _both must be there_; and to turn their equivalence into a universal formula, _all_ must be there. With only one kind of elementary matter, there can be no chemistry; with only the chemical elements and their laws, no life; with only vital resources, as in the vegetable world, no beginning of mind. But let Thought and Will with their conditions once be there, and they will appropriate vital power; as life, once in possession, will ply the alembics and the test-tubes of its organic laboratory; and chemical affinity is no sooner on the field than it plays its game among the cohesions of simple gravitation. Hence it is impossible to work the theory of Evolution upwards from the bottom. If all force is to be conceived as One, its type must be looked for in the highest and all-comprehending term; and Mind must be conceived as there, and as divesting itself of some specialty at each step of its descent to a lower stratum of law, till represented at the base under the guise of simple Dynamics. Or, if you retain the forces in their plurality, then you must _assume_ them _all_ among your data, and confess, with one of the greatest living expositors of the phenomena of Development, that unless among your primordial elements you scatter already the germs of mind as well as the inferior elements, the Evolution can never be wrought out.[15] But surely a theory, which is content simply to assume in the germ whatever it has to turn out full-grown, throws no very brilliant light on the genesis of the Universe.

ii. The second and principal support of the doctrine under review is found in the realm of natural history, and in that province of it which is occupied by _living beings_. Here, it is said, in the field of observation nearest to us, we have evidence of a power in each nature to push itself and gain ground, as against all natures less favorably constituted. There is left open to it a certain range of possible variations from the type of its present individuals, of which it may avail itself in any direction that may fortify its position; and even if its own instincts did not seize at once the line of greatest strength, still, out of its several tentatives, all the feeble results would fail to win a footing, and only the residuary successes would make good their ground. The ill-equipped troops of rival possibilities being always routed, however often they return, the well-armed alone are seen upon the field, and the world is in possession of "the fittest to live." We thus obtain a principle of self-adjusting adaptation of each being to its condition, without resorting to a designing care disposing of it from without; and its development is an experimental escape from past weakness, not a pre-conceived aim at a future perfection.

I have neither ability nor wish to criticise the particular indications of this law, drawn with an admirable patience and breadth of research, from every department of animated nature. Though the logical structure of the proof does not seem to me particularly solid, and the disproportion between the evidence and the conclusion is of necessity so enormous as to carry us no further than the discussion of an hypothesis, yet, for our present purpose, the thesis may pass as if established; and our scrutiny may be directed only to its bearings, should it be true.

(1) The genius of a country which has been the birthplace and chief home of Political Economy is naturally pleased by a theory of this kind; which invests its favorite lord and master, _Competition_, with an imperial crown and universal sway. But let us not deceive ourselves with mere abstract words and abbreviations, as if they could reform a world or even farm a sheep-walk. _Competition_ is not, like a primitive function of nature, an independent and original power, which can of itself do any thing: the term only describes a certain intensifying of power already there; making the difference, under particular conditions, between function latent and function exercised. It may therefore turn the less into the more; and it is reasonable to attribute to it an _increment_ to known and secured effects; but not new and unknown effects, for which else there is no provision. It gives but a partial and superficial account of the phenomena with which it has concern; of their degree; of their incidence here or there; of their occurrence now or then: of themselves in their characteristics it pre-supposes, and does not supply, the cause. To that cause, then, let us turn. Let us consider what must be upon the field, before competition can arise.
