The Scientific Basis of National Progress, Including that of Morality

1st. By founding State Laboratories. One of the first duties of a Government is to protect its subjects in the enjoyment of their property; but as no law reserves to discoverers the fruits of their ability, it is clearly a duty of the State to protect them in other ways. It is believed to be a duty of the State to provide and pay for pure scientific research, for the following reasons: – because research is eminently national work; because the results of such labour are indispensable to national welfare and progress, and are of immense value to the nation, and especially to the Government; because nearly the whole pecuniary benefit of it goes to the nation, and scarcely any to the discoverer; because research is not sufficiently provided for by means of voluntary effort, nor can its benefits be restricted to a locality; and because there appears to be scarcely any other way (except by application of University revenues) in which discoverers can be satisfactorily recompenced for their labour. Also "Government should for its own sake honour the men who do honour and service to the country." (Faraday.)

The founding of State laboratories for original research was proposed and advocated by the late Lieutenant-Colonel Strange, F.R.S., in communications read before the British Association, and in evidence given before the Royal Commissioners.33 As the erection and maintenance of State laboratories would require a large sum of money, and as all classes of the community would share in the benefit, it is reasonable to suggest that the money should come from some source towards which all classes of the community, either directly or indirectly contribute, and therefore from some national fund.

In national improvements, expense is quite a secondary consideration; the funds however for providing State laboratories already exist; the sum of nearly £600,000 has accumulated in the form of fees received by Government for the granting of patents for inventions; and as the discoveries made by scientific men form the materials by means of which those inventions were made, the money thus accumulated may be justly claimed by scientific discoverers as a suitable source from which their labours should be remunerated by the State.

Strong arguments might be adduced both against and in favour of the application of this money for the purpose. Inventors are a great wealth-producing class of the community; they are at present very highly taxed, and receive but little advantage in return; to tax them without giving them equivalent advantages, strikes very near to the root of commercial prosperity, by diminishing improvements in arts and manufactures. If an inventor is poor and his patent is valuable, he is also frequently harassed out of it by litigation. Inventors are usually poor, and but little able to pay taxes on patents at all; their pecuniary position in this country is not greatly better than that of discoverers; they are largely at the mercy of manufacturers and capitalists; and the injustice to which they are sometimes subjected is notorious and disgraceful. On the other hand, the fund already exists; inventors also receive an equivalent from investigators, discovery is the indispensable basis of nearly all invention; patented inventions are formed by means of the knowledge obtained by pure scientific research. The poverty of a man does not justify his taking the fruits of the labours of another man without paying for them. If also the patent fees were thus applied, the cost of research would then be paid for by all classes of the community, somewhat in proportion to the benefit derived, because the cost of patents in general ultimately falls upon the public at large, in the shape of an increased price put upon the commodity, in order to pay the cost of the patent, like the grower of wheat is paid by the consumers of bread, through the medium of the baker, the miller, and corn merchant.

Whilst the benefits derived from the labours of discoverers, flows chiefly in the form of money into the hands of wealthy manufacturers, and finally gets locked up in the possession of capitalists and landowners, it is hardly to be expected that the Government will be in possession of funds necessary to promote research unless some such plan as this is adopted. Should the wealthy and governing classes however become sufficiently acquainted with the value of research, and of the essential and permanent dependence of their material prosperity upon it, there will then be some hope that they will be willing to contribute in a more direct manner their just share towards paying the expenses. There is, however, but little prospect of this whilst the influence of wealth so depresses the scientific education of those classes at the Universities.

The fundamental object in founding State laboratories should be to keep a staff of the most competent men wholly engaged in original research in pure science, and a secondary object might be to train assistants to become investigators. Such laboratories would doubtless be located in London, and be on a scale of magnitude creditable to science and the nation. They might very suitably include departments for the simpler pure sciences and even for biology.

It is manifest that the arguments which support the proposition for professorships of original research in those sciences apply in a greater or less degree to other sciences; and it has been stated that "there is no ground upon which the scheme can be limited to the subject of natural philosophy." In reference to this remark, (which, like most objections, contains some truth), it must be remembered that there is a natural order of dependence of the sciences upon each other, in which order also they are being evolved. It is a general truth that the physical sciences of light and heat are based upon mechanical conditions of the particles of matter; that the science of chemistry is founded upon physics; that biological phenomena are dependent upon physical and chemical conditions; that psychological subjects are based upon biology; and that biological science cannot progress excepting in proportion to the advance of the sciences on which it is based. In addition to this general order of precedence of evolution in point of time, the various sciences are so mutually related that all must advance together, the simple ones taking the lead, and the concrete and more complex sciences, with their attendant arts, following behind.

As this natural order of dependence and development of the sciences is a great fact of nature, over which we have little or no control, and as a scheme for the simultaneous establishment of professorships of research in all the sciences, simple, complex, and concrete, would probably be too great an undertaking, the most proper course would be to commence with the simpler ones, such as those of mathematics, mechanics, physics, and chemistry, and perhaps biology. If it be argued that it would be unadvisable to commence with the simple and purely experimental sciences, it would be still more unadvisable to commence with the concrete subjects of "natural history, medicine, civil history, law, and theology," or with the arts which also depend upon science.

The number of investigators in such an institution would not be large, because few of high repute could be obtained, many of our ablest ones abandon research for remunerative pursuits. In order to make the plan succeed, the conditions of the appointments should be such as to limit the election to the most competent persons. In the selection of such gentlemen, the verdict of opinion of scientific men generally, upon the published researches of the candidates, would have previously determined who were qualified for the office. Any man who had published reliable papers in the Transactions of the Royal Society, might very properly be considered a fit candidate, and the selection and appointment might be made by the Government, with the advice of the Council of the Royal Society.

Probably there exists no class of persons upon whom the country might more rely for industry in office than eminent investigators, because they have pursued truth for its good effects alone. Men who had previously exercised the degree of self-sacrifice necessary to make a number of long and difficult experimental researches, with only very limited pecuniary means, must necessarily be possessed of great enthusiasm in their calling, and would therefore be extremely unlikely persons to become idle by being supplied with a sufficiency only of means to carry on their labours. Further, such men might at present obtain a much larger income than they would receive in such a post, by abandoning research and devoting themselves to the various profitable engagements which are open to every man of scientific ability who is willing to devote himself to applied science. The actual work of research is much too arduous and difficult to permit such an office to become an object of desire to a place-seeking or idle person. But in order to exclude with certainty those who might devote themselves to research solely or primarily for the purpose of subsequently obtaining a well paid appointment, (as persons sometimes devote themselves to learning, with the object of getting an "idle Fellowship,") and to ensure in all cases a reasonable continuance of industry, it would be necessary, that whilst the salaries paid should be sufficient to render the professors free from care, if expended with a reasonable degree of economy, they should not be so large as to conduce to idleness. The professors should undertake not to engage in any other remunerative employment, and provision should be made, that in case a professor persistently failed to make, complete, or publish his researches, or devoted less than the stipulated amount of time to such labour in the Institution, without reasonable cause, he should be removed.

Many persons fancy that "it must be very nice to be always making experiments," and that they "should be delighted with such an occupation" if they "could only spare the time." But such an idea is only another illustration of the general ignorance of the subject, and it is only expressed by those who have never made a laborious and difficult research. Pure research is by far the most difficult of all scientific occupations, and this is another chief reason why discoverers are few, and why they will probably remain so.

To succeed in research, a man must set aside all human pride, and approach the subject with perfect humility; and this is not an easy task, men cannot so readily abandon preconceived and cherished notions. Many researches are moreover extremely dangerous. Thilorier was killed by the explosion of a vessel of liquefied carbonic anhydride; Dulong lost an eye and finger, and Sir Humphrey Davy was wounded by an explosion of chloride of nitrogen. Faraday was near being blinded by an experiment with oxygen. Nicklès of Nancy, and Louyet of Brussels, lost their lives, and two other chemists were seriously injured in health by exposure to the excessively dangerous fumes of hydrofluoric acid. Bunsen lost the sight of an eye and was nearly poisoned by an explosion whilst analysing cyanide of cacodyl.34 Hennel was killed by an explosion of fulminate of silver, and Chapman by one of nitrate of methyl; and nearly every chemical investigator could tell of some narrow escape of life in his own experience. Any one who wishes to know whether it is "very nice to be always making experiments" should attempt the isolation of fluorine, the chemical examination of some offensive substance, or the determination of some difficult physical, or chemical problem.

That a professorship of original research would "involve substantial work" does not admit of doubt, and therefore "there would be some security that it would be worthily bestowed." It would not become an "ornamental sinecure," in which "there is pay but no work," unless, by assigning to it too large a stipend, inducement was held out to that numerous class of persons whose love of money is stronger than their love of truth, to seek the office; to say the utmost, it could hardly become so largely a sinecure as many offices now held by ecclesiastics. Jobbery and abuse of patronage would be still further prevented by making the duties sufficiently heavy.

The appointment, and remuneration by salary, of professor of research, would not lessen the independence of scientific men if the office was not placed under the superintendence of active and interfering officials ignorant of science. Although the professors might not be highly paid, the appointment would increase their independence because it would be one of the most honourable to which scientific men could attain, and because they would thereby be put into a sphere in which they could exercise their talents to the fullest extent, and render the greatest service and honour to the nation. If also the salaries offered were not too great, those persons only would become candidates who at present have insufficient means to defray the considerable cost of experiments.

It would be necessary to appoint only persons who would undertake to devote their time solely to the discovery of new facts and principles in science, and the determination of purely scientific questions, and not to the making of inventions; because discovery is of far greater national value than invention; and because inventions would immediately on their publication be seized, modified, and patented by individuals for their own personal benefit. Discoveries, on the other hand, would require a large additional amount of labour expended upon them by inventors before they could be converted into saleable commodities.

Each professor should be allowed perfect freedom to choose his own special subjects of research in the sciences he had been accustomed to study, because each investigator is usually the best judge of what researches are the most likely to yield him important results. No discoverer of repute would be very likely to trespass on another man's sphere of research, because he would usually have an abundance of good subjects of his own; and every honourable man would purposely avoid doing so; and we find this practically to be the case at the present time. Separate sets of rooms would be necessary for each investigator in order to keep the researches private and distinct.

The whole of the new knowledge obtained by research should be treated as national property, and all of it worthy of publication should be made known without the least reserve, it would also be desirable to publish the results at reasonable intervals of time. The publication might take place, as at present, in the journals of the learned Societies, or in the leading scientific magazines, and the value of the work would be largely guaranteed by such a mode of publication. The professors should also engage not to sell, patent, or prematurely disclose any of the knowledge obtained. By electing to such offices only discoverers of repute, the nation might reasonably depend for the results upon the known ability and industry of the men. That the results obtained would, many of them, be highly valuable, does not admit of doubt, because long experience has uniformly proved it; but no discoverer can tell beforehand what results he will obtain, otherwise research would hardly be needed.

An objection has been made that no one can tell how long it will be after a discovery is made before the nation will derive the chief benefit. The length of time which elapses between the publication of discoveries and their practical fruits is very variable. Usually benefit commences at once and gradually widens; directly discoveries are published they begin to be used by compilers of scientific books, and by teachers and lecturers in science, and are thus diffused amongst the public in general, and begin to produce beneficial effects. Inventors, manufacturers, medical men, and others, also begin to apply them to their respective purposes. In some cases striking applications are immediately made of them, and public attention is thus directed to the useful result; but in many cases the beneficial effects are small, numerous, and indirect, and it is difficult to trace and describe them. The objection also is deficient in force, because expenditure in any other occupation, and receipt of the profit upon it, are rarely simultaneous. Many of the wisest reforms in this country have been a long time in producing their results. We must therefore be content, as in all ordinary cases of investment, with the conviction that the expenditure will be profitable, and we must wait patiently for the certain harvest. In research, as in many other human enterprises, a man who will not move until he is absolutely certain that what he intends to do will at at once succeed, must sit still and perish.

Suggestions have also been made to appoint a Government Committee, or Council, whose function should be to value scientific discoveries, and make corresponding amounts of reward to the discoverers. But this appears to be a less feasible plan, because no man can, at the period of discovery, determine what amount of practical result a discovery will ultimately produce. Who could have foretold with certainty at the date of Oersted's discovery of electro-magnetism, that this discovery would result in the expenditure of hundreds of millions of pounds upon telegraphs alone?35

Objections have been made to definite payment for labour in research, on the ground of indefiniteness of the results, and the impossibility of measuring their value. Can we expect to buy new scientific knowledge at so much a pound, or to retail discovery by the pint? The work of discoverers is as definite as that of many other persons who are paid. Who can measure the value of the cure of souls, of the duties of a judge, or of those of a field-marshal? Instead of paying for the labour of research in a definite way, we have adopted unsatisfactory makeshifts. Exceptional gifts, and semi-charitable pensions, have been with difficulty obtained in a few cases for scientific men; most often for those who applied scientific knowledge to practical uses than for those who discovered that knowledge. In this country, neither lawyers, medical men, military persons, nor clergymen are paid definitely by results, but by time and labour, in accordance with the reputation of the man, and there is no sufficient reason why investigators should not be similarly remunerated. The differences in the cases are only ones of degree.

The time has arrived when this great evil should be made known and remedied, and men of science should press upon our Government, as a matter of justice to themselves, and necessary for the nation's welfare, that the accumulated fees from patents should be applied to the establishment of a Scientific department of the State, the erection of State laboratories, and the payment of discoverers for the national work of research.

2nd. Professorships of Research at the Universities. Most of the remarks already made respecting the appointment and maintenance of professors of research in State laboratories, would apply equally to those proposed in connection with the Universities. Amongst the reasons which may be adduced in favour of the establishment of such professorships the following may be selected. Because the advancement of learning is peculiarly the function of a University, and one of the chief objects for which such institutions were founded. The word University implies a seat of universal knowledge, and it is reasonable to assume that Universities should act as fountains of new theoretical knowledge, as well as perform the function of diffusing it; such an addition would also raise their intellectual position, and make them much more respected, both at home and abroad.

With regard to such professorships, the "Association for the Organization of Academical Study," consisting of a number of learned men belonging to the Universities, the Royal Society, and other learned bodies, adopted the following resolutions: —

"That the chief end to be kept in view in any redistribution of the revenues of Oxford and Cambridge is the adequate maintenance of Mature Study and Scientific Research, as well for their own sake as with the view of bringing the higher education within the reach of all who are desirous of profiting by it." "That to have a class of men whose lives are devoted to research is a national object." "That it is desirable, in the interest of national progress and education, that Professorships and special institutions shall be founded in the Universities for the promotion of Scientific Research." "That the present mode of awarding Fellowships as prizes, has been unsuccessful as a means of promoting Mature Study and Original Research, and that it is therefore desirable that it should be discontinued."

With regard to the funds necessary: – It has been estimated that the money paid in the form of sinecure fellowships or retiring pensions, to young men in Oxford alone now amounts to about £80,000 or £90,000 a year; and it has been suggested that this money be applied to the purpose. These funds were originally intended for promoting knowledge, but vested interests prevent their being used for discovering new truths.

The chief object of such professorships would be the same as that in the proposed State laboratories, viz. – to keep a staff of the most competent men wholly engaged upon research in pure science. The professors of physical and chemical research might be selected in accordance with the suggestions already made, and be appointed by the Senate or other governing body, with the advice of the Council of the Royal Society. All the precautions which have been already suggested under the head of "State laboratories," would have to be taken in order to exclude unsuitable persons, and to secure industry in the professors. The remarks also, already made respecting the limitation of the duties of the professors to research in pure science, the exclusion of invention, the publication of results, the class of sciences with which a commencement might best be made, etc., apply equally in this case. I do not however mean by these remarks to suggest the disendowment of research in the more complex or concrete subjects, in order to make a commencement with the simpler sciences.

The existence within the Universities of offices in which the faculties of scientific men might be developed to their fullest extent, would induce those engaged in the work of scientific instruction in those institutions to devote more time to research, in order that they might improve their scientific talents, and in their turn become fitted to occupy such posts.

It has been suggested that discoverers should teach as well as investigate; but this would be an imperfect plan, and would largely convert the position of a professor into that of one at an ordinary college. Every person who has had much experience in experimental investigation also knows, that to carry it out effectually, requires the whole of his time and attention. If, therefore, teaching or lecturing constitutes a part of the duties, a portion of the professor's time must be taken from the more important occupation of research, and the fundamental object of the institution will be frustrated. Research evolves new knowledge; teaching simply distributes it. The labours of a scientific teacher or lecturer consist essentially of a continued series of repetitions of other men's discoveries. For each single man who can discover, there exist many who can teach. With teaching in addition to research, all the usual educational machinery, lecture theatres and apparatus, diagrams, audiences, pupils, registration of students, receipt of fees, examinations, marking of papers, valuing of answers, attending annual meetings, etc., would be brought into requisition, and the result would probably be, as it is at present, the duties of teaching would, in nearly all cases, swallow up the time, and prevent the freedom from interruption necessary for successful research Under present circumstances, it is the testimony of nearly every teacher and lecturer in science, that he "has no time for research." If teaching is also carried on, the Research laboratories will compete with educational institutions, established and carried on by private enterprize, and place them at a disadvantage, and thus discourage voluntary effort in the diffusion of science; but by limiting the functions of the professors entirely to pure research, there will be no competition with any private interests, because no persons gain a livelihood entirely by means of such occupation.
