PHYSICAL SCIENCE IN ENGLAND
If Alexander and Archimedes, evoked from their long sleep, were to contemplate, with minds calmed by removal from contemporaneous interests, the state of mankind in the present year, with what different feelings would they regard the influence of their respective lives upon the existing human world of 1843! The Macedonian would find the empire which it was the labour of his life to aggrandize, frittered into parcels, modeled, remodeled, subjected to various dynasties; Turks, Greeks, Russians, still contending for portions of the territory which he had conjoined only to be dismembered; he would find in these little or no trace of his ever having existed; he would find that the unity of his vast political power had been severed before his body was yet entombed, and his prediction, that his funeral obsequies would be performed with bloody hands, verily fulfilled. In parts of the world which his living grasp had not seized, he would also see little to remind him of his past existence. Would not mortification darken the brow of the resuscitated conqueror on discovering, that when his name was mentioned in historic annals, it was less as a polar star to guide, than as a beacon to be avoided?
What would the Syracusan see in this present epoch to remind him of himself? Would he see the man of 212 b.c., at all connected with the men of 1843 a.d.? Yes. In Prussia, Austria, France, England, America, in every city of every civilized nation, he would find the lever, the pulley, the mirror, the specific gravimeter, the geometric demonstration; he would trace the influence of his mind in the power-loom, the steam-engine, in the building of the Royal Exchange, in the Great Britain steam-ship; he would find an application of his well-known invention, the subject of a patent, an important auxiliary to navigation. Alexander was a hero; Archimedes is one.
Are we guilty of exaggeration in this contrast of the hero of War with him of Science? We think not. It may undoubtedly be argued that Alexander's life was productive of ultimate good, that he did much to open Asia to European civilization; but would that consideration serve to soothe the gloomy Shade? To what does it amount but to the assertion that out of evil cometh good? It was through no aim of his mind that this resulted, nor are mankind indebted to him personally for a collateral effect of his existence.
As an instance of men of a more modern era, let us take Napoleon Buonaparte, Emperor of France, and James Watt of Greenock, civil engineer.
The former applied the energies of a sagacious and comprehensive intellect to his own political aggrandizement; the latter devoted his more modest talents to the improvement of a mechanical engine. The former was and is, par excellence, a hero of history—we should scarcely find in the works of the most voluminous annalists the name of the latter. What has Napoleon done to entitle his name to occupy so prominent a position? He has been the cause, mediate or immediate, of sacrificing the lives of two millions of men.17
Has the obscure Watt done nothing to merit a page in the records of mankind? Walk ten miles in any manufacturing district, enter any coal-mine, examine the bank of England, travel by the Great Western railway, or navigate the Danube, the Mediterranean, the Indian or the Atlantic Ocean—in each and all of these, that giant slave, the steam-engine, will be seen, an ever-living testimony to the services rendered to mankind by its subjugator.
Attachment to a favourite pursuit is undoubtedly calculated to bias the judgment; but, however liable may be the obscure votary of science to override his hobby, Francis Bacon, Lord High Chancellor of England, in ascribing to scientific discoverers a higher merit than to legislators, emperors, or patriots, cannot be open to the charge of egoistic partiality. What, then, says this illustrious witness?—"The introduction of noble inventions seems to hold by far the most excellent place among all human actions. And this was the judgment of antiquity, which attributed divine honours to inventors, but conferred only heroical honours upon those who deserve well in civil affairs, such as the founders of empires, legislators, and deliverers of their country. And whoever rightly considers it, will find this a judicious custom in former ages, since the benefits of inventors may extend to all mankind, but civil benefits only to particular countries or seats of men; and these civil benefits seldom descend to more than a few ages, whereas inventions are perpetuated through the course of time. Besides, a state is seldom amended in its civil affairs without force and perturbation; whilst inventions spread their advantage without doing injury or causing disturbance."18
The opinion of a man who had reached the highest point to which a civilian could aspire, cannot, when he estimates the honours of the Chancellor as inferior to those of the natural philosopher, be ascribed to misjudging enthusiasm or personal disappointment. Without, however, seeking, for the sake of antithetic contrast, to underrate the importance of political services, civil or military, or to exaggerate those of the man of science, few, we think, will be disposed to deny that, although the one may be temporarily more urgent and necessary to the well-being of an existing race, yet that the benefits of the other are more lasting and universal. If, then, the influence on mankind of the secluded inventor be more extensive and durable than that of the active politician—if there be any truth in the opinion of Bacon, that the greatest political changes are wrought by the peaceful under-current of science; why is it that those who occupy the highest place as permanent benefactors of mankind, are, during their lifetime, neglected and comparatively unknown;—that they obtain neither the tangible advantages of pecuniary emolument, nor the more suitable, but less lucrative, honours of grateful homage? It is the common cry to exclaim against the neglect of science in the present day. Alas! history does not show us that our predecessors were more just to their scientific contemporaries. The evil is to a great extent remediless, the complaint to some extent irrational, and unworthy the dignity of the cause. The labourer in the field of science works not for the present, but for succeeding generations; he plants oaks for posterity, and must not look for the gratitude of contemporaries. Men will remunerate less, and be less grateful for, prospective than for present good—for benefits secured to their posterity than to themselves; the realization of the advantages is so distant, that the amount of discount is coextensive with the debt: it is only as the applications of science become more immediate, that the cultivators of science can reasonably expect an adequate reward or appreciation.
Even when practically applied, we too frequently see that the original discoveries of the physical philosopher are but little valued by those who make a daily, a most extensive, and a most lucrative use of their results. Men talk of "a million;" how few have ever counted one! Men walk along the Strand, Fleet Street, Ludgate Hill; how few think of the multiplied passions and powers which flit by them on their way—of the separate world which surrounds each passer-by—of the separate history, external and internal, of each—each possessing feelings, motives of action, characters, differing from the others, as the stamp of nature on his brow differs from his fellows! Thus, also, men's ears ring with the advancement of science, men's beards wag with repetition of the novel powers which have been educed from material nature; and if, in our daily traffic, we traverse without attention countless sands of thought, how much more, in our hackneyed talk of science, do we neglect the debt we owe to thought—thought, not the mere normal impulse of humanity, but the carefully elaborated lucubration of minds, of which the term thinking is emphatically predicable! Names which are met with but once in the annals of science, and there, dimly seen as a star of the least magnitude, have perhaps earned that remote and obscure corner by painful self-denial, by unwearied toil! And yet not only these, but others who have added to diligence high mental acumen or profundity, whose wells of thought are, compared with those of the general mass, unfathomable, earn but a careless, occasional notice—are known but to few of those who daily reap the harvest which they have sown, and who even boast of seeing further than they did, as the dwarf on the shoulders of a giant can see further than the giant. The first step of the unthinking is to deny the possibility of a given discovery, the next is to assert that any one could have foreseen such discovery.
There are, however, points of higher import than gain or glory to which the philosopher must ever look, and the absence of which must be a source of bitter disappointment and ground of just complaint. The most important of these is, that, by national neglect, the cause of science is injured, her progress retarded. Not only is she not honoured, she is dishonoured; and in no civilized nation is this contempt of physical science carried to a greater extent than in England, the country of commerce and of manufactures.
In this country, should a father observe in his gifted son a tendency to physical philosophy, he anxiously endeavours to dissuade him from this career, knowing that not only will it tend to no worldly aggrandizement, but that it will have the inevitable effect of lowering his position in what is called, and justly called, good society—the society of the most highly educated classes. At one of our universities, physical science is utterly neglected; at the other, only certain branches of it are cultivated. There are, it is true, university professors of each branch of physics, some of whom are able to collect a moderate number of pupils; others are obliged to carry with them an assistant, to whom alone they lecture, as Dean Swift preached to his clerk. But what part of the regular academic education does the study of Natural Philosophy occupy? It forms no necessary part of the examinations for degrees; no credit is attached to those who excel in its pursuit; no prizes, no fellowships, no university distinction, conferred upon its most successful votaries. On the contrary, physical, or at all events experimental, science is tabooed; it is written down "snobbish," and its being so considered has much influence in making it so: the necessity of manipulation is a sad drawback to the gentlemanliness of a pursuit. Bacon rebuked this fastidiousness, but in vain. "We will, moreover, show those who, in love with contemplation, regard our frequent mention of experiments as something harsh, unworthy, and mechanical, how they oppose the attainment of their own wishes, since abstract contemplation, and the construction and invention of experiments, rest upon the same principles, and are brought to perfection in a similar manner."19
Unfortunately, the fact of experimental science being rejected by the educated classes and thrown in a great measure upon the artizans of a country, has conducted, among other evils, to one of a most detrimental character; viz. the want of accuracy in scientific language, and consequently the want of accuracy in ideas. Perfection in language, as in every thing else, is not to be attained, and doubtless there are few of the most highly educated who would not, in many cases, assign different meanings to the same word; but if some confusion on this subject is unavoidable, how much is that confusion increased, as regards scientific subjects, by the mass of memoirs written by parties, who, however acute their mental perceptions may be, yet, from want of early education, do not assign to words that accuracy of signification, and do not possess that perspicuity of style, which is absolutely necessary for the communication of ideas! Those, therefore, who, with different notions of language, read the writings of such as we are alluding to, either fail to attach to them any definite meaning, or attach one different from that which the authors intended to convey; whence arises a want of reciprocal intelligence, a want of unity of thought and purpose. Another defect arising from the circumstance that persons of a high order of education have not been generally the cultivators of experimental science in this country, is, that the path is thereby rendered more accessible to empiricism. Science, beautiful in herself, has thence a class of deformed disciples, who succeed in entangling their false pretensions with the claims of true merit. So much dust is puffed into the eyes of the public, that it can hardly distinguish between works of durable importance and the ephemeral productions of empirics; and those who would otherwise disdain the notoriety acquired by advertisement, end in adopting the system as the only means to avoid the mortification of seeing their own ideas appropriated and uttered in another form and in another's name.20
While the evils to which science is exposed by the necessarily unfashionable character of experimental manipulation are neither few nor trivial, there are still evils which arise from the directly opposite cause—from excess of intellectual cultivation; as is shown in the exclusive love of mathematics by a great number of philosophers. Minds which, left to themselves, might have eliminated the most valuable results, have, dazzled by the lustre cast by fashion upon abstract mathematical speculations, lost themselves in a mazy labyrinth of transcendentals. The fashion of mathematics has ruined many who might be most useful experimentalists; but who, wishing to take a higher flight, seek to attain distinction in mathematical analysis, and having acquired a certain celebrity for experimental research, dissipate, in simple equations, the fame they had acquired in a field equally productive, but not so select. Like Claude, who in his later years said, "Buy my figures, and I will give you my landscapes for nothing;" they fall in love with their own weakness, and estimate their merit by the labour they have undergone, not by the results they have deduced. M. Comte expresses himself well on this subject. "Mathematicians, too frequently taking the means for the end, have embarrassed Natural Philosophy with a crowd of analytical labours, founded upon hypotheses extremely hazardous, or even upon conceptions purely visionary; and consequently sober-minded people can see in them really nothing more than simple mathematical exercises, of which the abstract value is sometimes very striking, without their influence, in the slightest degree, accelerating the natural progress of Physics."21
The cultivators of science, despite the want of encouragement, have, like every other branch of the population, increased rapidly in number, and, being thrown upon their own resources, have organized Societies, the number of which is daily increasing, which do much good, which do much harm. They do good, in so far as they carry out their professed objects of facilitating intercourse between votaries of similar branches of study—they do good by the more attainable communication of the researches of those who cannot afford, or will not dare, the ordinary channels of publication; but who, sanctioned by the judgment of a select tribunal, are glad to work and to impart to the public the fruits of their labour—they give an esprit de corps, which forms a bond of union to each section, and induces a moral discipline in its ranks. The investment of their funds in the collection of libraries or of apparatus, the use of which becomes thus accessible to individuals, to whom otherwise such acquisitions would have been hopeless, is another meritorious object of their institution; an object in many cases successfully carried out. On the other hand, they do harm, by becoming the channels of selfish speculation, their honorary offices being used as stepping-stones to lucrative ones, thereby causing their influential members to please the givers of "situations," and to publish the trash of the impertinently ambitious, the Titmice of the Credulous Societies! The ultra-ridiculous parade with which they have decked fair science, giving her a vest of unmeaning hieroglyphics, and thereby exposing her to the finger of scorn, is another prominent and unsightly feature of such societies; they do harm by the cliquerie which they generate, collecting little knots of little men, no individual of whom can stand his own ground, but a group of whom, by leaning hard together, can, and do, exercise a most pernicious influence; seeking petty gain and class celebrity, they exert their joint-stock brains to convert science into pounds, shillings, and pence; and, when they have managed to poke one foot upon the ladder of notoriety, use the other to kick furiously at the poor aspirants who attempt to follow them.
It has been frequently and strenuously urged, that these societies, or some of them, should be supported by government, and not dependent upon the subscriptions of their members. The arguments in favour of such a measure are, that by thus being accessible only to merit, and not depending upon money, their position would be more honourable and advantageous to the progress of science. With regard to such societies generally, this proposition is incapable of realization; every year sees a new society of this description; to annex many of these to government, would involve difficulties which, in the present state of politics, would be insurmountable. Who, for instance, would pay taxes for them? Another, and more reasonable, proposition is, that the government should establish and support one academy as a head and front of the others, accessible only to men of high distinction, who would be thus constituted the oligarchs of science. Of the advantage of this we have some doubts. Politics are already too much mixed up with all government appointments in England: their influence is at present scarcely felt in science, and we would not willingly risk an introduction so fraught with danger. The want of such an academy certainly lessens the English in the eyes of the continental savans; but could not such a one be organized, and perhaps endowed, by government, without any permanent connexion with it?
If we compare the proceedings, undoubtedly dignified and decorous, of our Royal Society with those of the French Academy, we fear the balance will be found to be in favour of the latter. At Somerset House, after the list of donations and abstract of former proceedings, a paper, or a portion of a paper, is read upon some abstruse scientific subject, and the meeting is adjourned in solemn silence, no observation can be made upon it, no question asked, or explanation given. The public is excluded,22 and the greater part of the members generally exclude themselves, very few having resolution enough to leave a comfortable dinner-table to bear the solemn formalities of such an evening. The paper is next committed, it is not known to whom, reported on in private, and either published, or deposited in the archives of the Society, according to the judgment of the unknown irresponsible parties to whom it is committed. Let us now look at the proceedings of the French Academy; it is open to the public, and the public take so great an interest in it, that to secure a seat an early attendance is always requisite. Every scientific point of daily and passing interest is brought before it—comments, such as occur at the time, are made upon various points by the secretary, or any other member who likes to make an observation—the more elaborate memoirs are read by the authors themselves, and if any quære or suggestion occurs to a member present, he has an opportunity of being answered. The memoir is then committed to parties whose names are publicly mentioned, who bring out their report in public, which report is read in public, and may be answered by the author if he object to it. Lastly, the whole proceedings are printed and published verbatim, and circulated at the next weekly meeting, while, in the mean time, the public press notices them freely. That, with all these advantages, the French Academy is not free from faults, we are far from asserting; that there is as much unseen manœuvring and petty tyranny in this as in most other institutions, is far from improbable;23 but the effect upon the public, and the zest and vitality which its proceedings give to science, are undeniable, and it is also undeniable that we have no scientific institution approaching to it in interest or value.
The present perpetual secretary of the Academy, Arago, with much of prejudice, much of egotism, has talents most plastic, an energy of character, an indomitable will, a force and perspicuity of expression, which alone give to the sittings of the French Academy a peculiar and surpassing interest, but which, in the English Society, would be entirely lost.
In quitting, for the present, the subject of scientific societies, we must advert to a consequence of the increased number of candidates for scientific distinction of late years; of which increase the number of these societies may be regarded as an exponent. This increase, although on the whole both a cause and a consequence of the advancement of science, yet has in some respects lowered the high character of her cultivators by the competition it has necessarily engendered. Books tell us that the cultivation of science must elevate and expand the mind, by keeping it apart from the jangling of worldly interests. This dogma has its false as well as its true side, more especially when in this, as in every other field of human activity, the number of competitors is rapidly increasing; great watchfulness is requisite to resist temptations which beset the aspirant to success on this arena, more perhaps than in any other. The difficulty which the most honest find to avoid treading in the footsteps of others—the different aspect in which the same phenomena present themselves to different minds—the unwillingness which the mind experiences in renouncing published but erroneous opinions—are points of human weakness which, not to mislead, must be watched with assiduous care. Again, the ease with which plagiarism is committed from the number of roads by which the same point may be reached, is a great temptation to the waverer, and a great trial of temper to the victim. The disputants on the arenæ of law, politics, or other pursuits, the ostensible aim of which is worldly aggrandizement, however animated in debate, unsparing in satire, reckless in their invective and recrimination, seldom fail in their private intercourse to throw off the armour of professional antagonism, and to extend to each other the ungloved hand of social cordiality. On the other hand, it is too frequent a spectacle in scientific circles to behold a careful wording of public controversy, a gentle, apologetic phraseology, a correspondence never going beyond the "retort courteous," or "quip modest," while there exists an under-current of the bitterest personal jealousy, the outward philosopher being strangely at variance with the inward man.
Among the various circumstances which influence the progress of physical science in this country, one of the most prominent is the Patent law—a law in its intention beneficent; but whether the practical working of it be useful, either to science or its cultivators, is a matter of grave doubt. Of the greater number of patents enrolled in that depot of practical science, Chancery Lane, by far the majority are beneficial only to the revenue; and on the question of public economy, whether or not the price paid by miscalculating ingenuity is a fair and politic source of revenue, we shall not enter; but on the reasons which lead so many to be dupes of their own self-esteem, a few words may not be misspent. The chief reason why a vast number of patents are unsuccessful, is, that it takes a long time (longer generally than fourteen years, the statutable limit of patent grants) to make the workmen of a country familiar with a new manufacture. A party, therefore, who proposes patenting an invention, and who sits down and calculates the value of the material, the time necessary for its manufacture, and other essential data; comparing these with the price at which it can be sold to obtain a remunerative profit, seldom takes into consideration the time necessary, first, to accustom the journeymen workers to its construction, and secondly, to make known to the public its real value. In the present universal competition, puffing is carried on to such an extent, that, to give a fair chance of success, not only must the first expense of a patent be incurred—no inconsiderable one either, even supposing the patentee fortunate enough to escape litigation—but a large sum of money must be invested in advertisements, with little immediate return; hence it is that the most valuable patents, viewed in relation to their scientific importance, their ultimate public benefit, and the merits of their inventors, are seldom the most lucrative, while a patent inkstand, a boot-heel, a shaving case, or a button, become rapidly a source of no inconsiderable profit. Is this beneficial to inventors? Is it an encouragement of science, or a proper object of legislative provision, that the improver of the most trivial mechanical application should be carefully protected, while those who open the hidden sources of myriads of patents, are unrewarded, and incapable of remunerating themselves? We seriously incline to think that, as the matter at present stands, an entire erasure from the statute-books of patent provision would be of service to science, and perhaps to the community; each tradesman would depend for success upon his own activity, and the perfection he could give his manufacture, and the scientific searcher after experimental truths would not find his path barred by prohibitions from speculative empirics.
According to the present patent laws, it is more than questionable whether the discoverer of a great scientific principle could pursue his own discovery, or whether he would not be arrested on the threshold by a subsequent patentee; if Jacobi lived in constitutional England instead of despotic Russia, it is doubtful if he could work out his discovery of the electrotype—we say doubtful; for, as far as we can learn, it seems hitherto judicially undecided whether the mere use of a patent, not for sale or a lucrative object, is such a use within the statute of James as would be an infringement of a patentee's rights. It appears to be settled, that a previous experimental and unpublished use by one party, does not prevent another subsequent inventor of the same process from patenting it; and, by parity of reasoning, we should say, that if a party have the advantage of patenting an invention which can be found to have been previously used, but not for sale, he should not have the additional privilege of prohibiting the same party, or others, from proceeding with their experiments. There are, however, not wanting arguments for the other view. The practice of a patented invention, for one's own benefit or pleasure, deprives the patentee of a possible source of profit; for it cannot be said that the party experimenting, if prohibited, might not apply for a license to the patentee. Take, for instance, the notorious and justly censured patent of Daguerre. Supposing, for argument's sake, this patent to be valid, can a private individual, under the existing patent laws, take photographic views or portraits for his own amusement, or in pursuance of scientific investigations? If he cannot, then is an exquisitely beautiful path of physics to be shut up for fourteen years; or if he can, then is the licensee, a purchaser for value, to be excluded from very many sources of pecuniary emolument? To us, the injury to the public, in this and similar cases, appears of incomparably greater consequence than that to the individual; but what the authorities at Westminster Hall may say is another question. Even could the patent laws be so modified, that the benefits derived from them could fall upon those scientific discoverers most justly entitled, we are still doubtful as to their utility, or whether they would contribute to the advancement of science, which is the point of view in which we here principally regard them. It would scarcely add to the dignity of philosophy, or to the reverence due to its votaries, to see them running with their various inventions to the patent office, and afterwards spending their time in the courts of law, defending their several claims. They would thus entirely lose the respect due to them from their contemporaries and posterity, and waste, in pecuniary speculation, time which might be more advantageously, and without doubt more agreeably, employed. If parties look to money as their reward, they have no right to look for fame; to those who sell the produce of their brains, the public owes no debt.
We have observed recently a strong tendency in men of no mean scientific pretensions to patent the results of their labours. We blame them not: it is a matter of free election on their part, but we cannot praise them. A writer in a recent number of the Edinburgh Review, has the following remarks on the subject of Mr Talbot's patented invention of the Calotype. "Nor does the fate of the Calotype redeem the treatment of her sister art, (the Daguerreotype.) The Royal Society, the philosophical organ of the nation, has refused to publish its processes in her transactions. * * * No representatives of the people unanimously recommended a national reward. * * * It gives us great pleasure to learn, that though none of his (Mr Talbot's) photographical discoveries adorn the transactions of the Royal Society, yet the president and the council have adjudged him the Rumford medals for the last biennial period."24
