THE NOBILITY OF KNOWLEDGE.

_An Address delivered before the Free Institute at Worcester,

Massachusetts, July 28, 1874._

Within a comparatively few years schools for the instruction of artisans

have become a prominent feature in the educational systems both of this

country and of Europe, and seem destined to supersede the old system of

apprenticeships. The establishment of these schools has been an

important step in human progress, not because any great advantage has

been gained in the cultivation of mechanical skill, but because here the

future mechanic acquires culture of the mind as well as skill of the

hand. Indeed, it may be doubted whether our utilitarian age can ever

successfully compete with those "elder days of art" when

"Builders wrought with greatest care

Each minute and unseen part."

But, if our industrial schools do not make better mechanics than the

workshops of the olden time, they certainly educate better men, and, by

adding to skill, knowledge, they are elevating the mechanic and

ennobling his calling.

If, therefore, these schools are the representatives in our age of the

workshops with their bands of apprentices in the days of yore, then that

by which the schools are distinguished, that which they have added to

the old system, is not art but mental culture; and therefore, when asked

to address you on this occasion, I could think of no more appropriate

subject than the Nobility of Knowledge.

Identified with an institution in which mental culture is the chief aim,

I felt that I was asked to address a body of cultivated working-men with

whom, though employed in the mechanic arts, the acquisition of knowledge

was also a privilege and a pride. I felt, moreover, that a proper

appreciation of the true dignity of knowledge, in itself considered, and

apart from all economical considerations, is one of the great wants of

our age and of our country.

"Knowledge is power." "Knowledge is wealth." These trite maxims are

sufficiently esteemed in our community, and need not that they be

enforced by any one. So far as knowledge will yield immediate

distinction or gain, it is sought and fostered by multitudes. But, when

the aim is low, the attainment is low, and too many of our students are

satisfied with superficiality, if it only glitters, and with

charlatanry, if it only brings gold.

Let me not be understood to depreciate the material advantages of

learning. I rejoice that in this world knowledge frequently yields

wealth and fame, and I should have little hope for human progress were

the prizes of scholarship less than they are. Power and wealth are noble

aims, and when rightly used may be the means of conferring unmeasured

blessings on mankind; but I desire at this time to impress upon you, my

friends, the fact that knowledge has nobler fruits than these, and that

the worth of your knowledge is to be measured not by the credits it will

add to your account in the ledger, or the position it may give you among

men, but by the extent to which it educates your higher nature, and

elevates you in the scale of manhood.

I address young men who are just entering on life, who are at an age

when the mystery of our being usually presses most closely upon the

soul, and whose aspirations for higher culture and clearer vision have

not been deadened by the sordid damps of the world. Trust no croakers

who tell you that your youthful visions are illusions, which a little

contact with the real business of the world will dispel.

It is only too true that these visions will become fainter and fainter,

if you allow the cares of the world to engross your thoughts; but,

unless your higher nature becomes wholly deadened, you will look back to

the time when the visions were brightest, as the golden period of your

life, and let me assure you that, if you only are true to the

aspirations of your youth, the visions will become clearer and clearer

to the last, and, as we firmly believe, will prove to be the dawn of the

perfect day.

My friends, if you have seen these visions, "the nobility of knowledge"

has been a reality of your experience. You know that there is a life

lived in communion with the thoughts of great men or with the thoughts

of God as we can read them in Nature and Revelation, which is purer and

nobler than a life of money-making or political intrigue, and I would

that I could so bring you to appreciate not only the nobility, but also

the happiness, of such a life as to induce you to try to live it.

Do you tell me that it is only granted to a few men to become scholars,

and that you have been educated for some industrial pursuit? Remember,

as I said before, that it is your special privilege to have been

educated, to have added knowledge to your handicraft, and that this very

knowledge, if kept alive so far as you are able, will ennoble your life.

Knowledge, like the fairy's wand, ennobles whatever it touches. The

humblest occupations are adorned by it, and without it the most exalted

positions appear to true men mean and low.

Nor is it the extent of the knowledge alone which ennobles, but much

more the spirit and aim with which it is cultivated, and that spirit and

aim you may carry into any occupation, however engrossing, and into any

condition of life, however obscure.

And let me add that what I have said is true not only of the individual,

but also, and to an even greater degree, of the nation. Our people, for

the most part, look upon universities and other higher institutions of

learning as merely schools for recruiting the learned professions, and

estimate their efficiency solely by the amount of teaching work which

they perform. But, however important the teaching function of the

university may be, I need not tell you that this is not its only or

chief value to a community. The university should be the center of

scientific investigation and literary culture, the nursery of lofty

aspirations and noble thoughts, and thus should become the soul of the

higher life of the nation. For this and this chiefly it should be

sustained and honored, and no cost and no sacrifice can be too great

which are required to maintain its efficiency; and its success should be

measured by the amount of knowledge it produces rather than by the

amount of instruction it imparts.

Harvard College, by cherishing and honoring the great naturalist she

has recently lost, has done more for Massachusetts than by educating

hosts of commonplace professional men. The simple title of teacher,

which in his last will Louis Agassiz wrote after his name, was a nobler

distinction than any earthly authority could confer; but remember he was

a teacher not of boys, but of men, and his influence depended not on the

instruction in natural history which he gave in his lecture-room, but on

his great discoveries, his far-reaching generalization, and his noble

thoughts. Although that man died poor, as the world counts poverty, yet

the bequest which he left to this people can not be estimated in coin.

It is a sorry confession to make, but it is nevertheless the truth,

that, if we compare our American universities, in point of literary or

scientific productiveness, with those of the Old World, they will appear

lamentably deficient. Let me add, however, that this deficiency arises

not from any want of proper aims in our scholars, but simply from the

circumstance that our people do not sufficiently appreciate the value of

the higher forms of literary and scientific work to bear the burden

which the production necessary entails. Scholars must live, as well as

other men, and in a style which is in harmony with their surroundings

and cultivated tastes, and their best efforts can not be devoted to the

extension of knowledge unless they are relieved from anxiety in regard

to their daily bread.

In our colleges the professors are paid for teaching and for teaching

only, while in a foreign university the teaching is wholly secondary,

and the professor is expected to announce in his lectures the results of

his own study, and not the thoughts of other men. Until the whole status

of the professors in our chief universities can be changed, very little

original thought or investigation can be expected, and these

institutions can not become what they should be, the soul of the higher

life of the nation.

It is in your power, however, to bring about this change, but the reform

can be effected in only one way. You must give to your universities the

means of supporting fully and generously those men of genius who have

shown themselves capable of extending the boundaries of human knowledge,

and demand of them, only, that they devote their lives to study and

research, and let me assure you that no money can be spent which will

yield a larger or more valuable return.

If you do not look beyond your material interests, the higher life of

the nation, which you will thus serve to cherish and foster, will guard

your honor and protect your home; and, on the other hand, what can you

expect in a nation whose highest ideal is the dollar or what the dollar

will buy, but venality, corruption, and ultimate ruin?

But, rising at once to the noblest considerations, and regarding only

the welfare of your country and the education of your race, what higher

service can you render than by sustaining and cherishing the grandest

thought, the purest ideals, and the loftiest aspirations which humanity

has reached, and making your universities the altars where the holy fire

shall be kept ever burning bright and warm?

Do you think me an enthusiast? Look back through history, and see for

yourselves what has made the nations great and glorious. Why is it that,

after twenty centuries, the memory of ancient Greece is still enshrined

among the most cherished traditions of our race? Is it not because Homer

sang, Phidias wrought, and Plato, Aristotle, Demosthenes, Thucydides,

with a host of others, thought and wrote? Or, if for you the military

exploits of that classic age have the greater charm, do not forget that

were it not for Grecian literature, Thermopylae, Marathon, and Salamis

would have been long since forgotten, and that the bravery,

self-devotion, and patriotism which these names embalm were the direct

fruits of that higher life which those great thinkers illustrated and

sustained.

And, coming down to modern times, what are the shrines in our mother

country which we chiefly venerate, and to which the transatlantic

pilgrim oftenest directs his steps? Is it her battlefields, her castles

and baronial halls, or such spots as Stratford-on-Avon, Abbotsford, and

Rydal Mount? Why, then, will we not learn the lesson which history so

plainly teaches, and strive for those achievements in knowledge and

mental culture which will be remembered with gratitude when all local

distinctions and political differences shall have passed away and been

forgotten?

While I was considering the line of discourse which I should follow on

this occasion, an incident occurred suggesting an historical parallel,

which will illustrate, better than any reflections of mine, the truth I

would enforce. The ship Faraday arrived on our coast after laying over

the bed of the Atlantic another of those electric nerves through which

pulsate the thoughts of two continents, and as I read the description of

that noble ship, fitted out with all the appliances which modern science

had created to insure the successful accomplishment of the enterprise, I

remembered that not a century had elapsed since the first obscure

phenomena were observed, whose conscientious study, pursued with the

unselfish spirit of the scientific investigator, had led to these

momentous results, and my imagination carried me back to an autumn day

of the year 1786, in the old city of Bologna, in Italy, and I seemed to

assist at the memorable experiment which has associated the name of

Aloysius Galvani with that mode of electrical energy which flashes

through the wire cords that now unite the four quarters of the globe.

Galvani is Professor of Anatomy in the University of Bologna, and there

is hanging from the iron balcony of his house a small animal

preparation, which is not an unfamiliar sight in Southern Europe, where

it is regarded as a delicacy of the table. It is the hind-legs of a

frog, from which the skin had been removed, and the great nerve of the

back exposed. Six years before, his attention had been called to the

fact that the muscles of the frog were convulsed by the indirect action

of an electrical machine, under conditions which he had found very

difficult to interpret. He had connected the phenomenon with a theory of

his own: that electricity--that is, common friction electricity, the

only mode of electrical action then known--was the medium of all nervous

action; and this had led him into a protracted investigation of the

subject, during which he had varied the original experiment in a

thousand ways, and he had now suspended the frog's legs to the iron

balcony, in order to discover if atmospheric electricity would have any

effect on the muscles of the animal.

Galvani has spent a long day in fruitless watching, when, while holding

in his hand a brass wire, connected with the muscles of the frog, he

rubs the end, apparently listlessly, against the iron railing, when,

lo! the frog's legs are convulsed.

The patient waiting had been rewarded, for this observation was the

beginning of a line of discovery which was ere long to revolutionize the

world. But Galvani was not destined to follow far the new path he had

thus opened. The remarkable fact observed was this: The convulsions of

the frog's legs could be produced without the intervention of

electricity, or, at least, of the one kind of electricity then known,

and Galvani soon found out that the only condition necessary to produce

the result was, that the nerve of the frog should be connected with the

muscle of the leg by some good electrical conductor.

But, although Galvani followed up this observation with the greatest

zeal, and showed remarkable sagacity throughout his whole investigation,

yet he was too strongly wedded to his own theory to interpret correctly

the facts he observed. He supposed, to the end of his life, that the

whole effect was caused by animal electricity flowing through the

conductor from the nerve to the muscle, and his experiments were chiefly

interesting to himself and to his contemporaries from the light they

were supposed to throw on the mysterious principle of life. We now know

that animal electricity played only a small part in the phenomena he

observed, and that the chief effects were due to a cause of which he

was wholly ignorant.

Galvani published his observations in 1791, in a monograph entitled "The

Action of Electricity in Muscular Motion." This publication excited the

most marked attention, and, within a year, all Europe was experimenting

on frogs' legs. The phenomena were everywhere reproduced, but Galvani's

explanation of the phenomena was by no means so universally accepted.

His theory was controverted in many quarters, and by no one more

successfully than by Alexander Volta, Professor of Physics in the

neighboring University of Pavia.

Volta, while admitting, with Galvani, that the muscular contractions

were caused by electricity, explained the origin of the electricity in a

wholly different way. According to Volta, the electricity originated not

in the animal, but in the contact of the dissimilar metals or other

materials used in the experiment. This difference of opinion led to one

of the most remarkable controversies in the history of science, and for

six years, until his death in 1798, Galvani was occupied in defending

his theory of animal electricity against the assaults of his

distinguished countryman.

This discussion created the liveliest interest throughout Europe. Every

scholar of science took sides with one or the other of these eminent

Italian philosophers, and the scientific world became divided into the

school of Galvani and the school of Volta. Yet, so far at least as the

fundamental experiment was concerned, both were wrong. The electricity

came neither from the body of the frog nor from the contact of

dissimilar kinds of matter, but was the result of chemical action, which

both had equally overlooked.

But, nevertheless, the controversy led to the most important results:

for Volta, while endeavoring to sustain his false theory by experimental

proofs, was led to the discovery of the Voltaic pile, or, as we now call

it, the Voltaic battery, an instrument whose influence on civilization

can be compared only with the printing-press and the steam-engine. Yet,

although the whole action of the battery was in direct contradiction to

his pet theory, still, to the last, Volta persistently defended the

erroneous doctrine he had espoused in his controversy with Galvani

thirty years before, and he died in 1827, without realizing how great a

boon he had been instrumental in conferring on mankind; so true it is

that Providence works out his bright designs even through the blindness

and mistakes of man.

But there is another lesson to be learned from this history, which can

not be too often rehearsed in this self-sufficient age, which boasts so

proudly of its practical wisdom. There were, doubtless, many practical

men in that city of Bologna to smile at their sage professor, who had

spent ten long years in studying, to little apparent purpose, the

twitchings of frogs' hind-legs, and there was many a jest among the

courtiers of Europe at the expense of the learned philosophers who

"wasted" so much time in discussing the cause of such trivial phenomena.

But how is it now?

Less than a century has passed since Galvani's death, and in a small hut

on the shores of Valentia Bay may be seen one of the most skillful of a

new class of practical men, representing a profession which owes its

origin to Galvani and Volta. The _electrician_ is watching a spot of

light on the scale of an instrument which is called a _galvanometer_.

Since the fathers fell asleep, the field of knowledge which they first

entered has spread out wider and wider before the untiring explorers who

have succeeded them. Oersted and Seebeck, Arago and Ampere, Faraday and

our own Henry, have made wonderful discoveries in that field; and other

great men, like Steinheil, Wheatstone, Morse, and Thomson, have invented

ingenious instruments and appliances, by which these discoveries might

be made to yield great practical results.

The spot of light, which the electrician is watching, is reflected from

one of the latest of these inventions, the reflecting galvanometer of

Thomson. He and his assistants had been watching by turns the same spot

for several days, since the Great Eastern had steamed from the bay,

paying out a cable of insulated wire. These electricians had no anxiety

as to the result, for daily signals had been exchanged between the ship

and the shore, as hundreds after hundreds of miles of this electrical

conductor had been laid on the bed of the broad ocean. The coast of

Newfoundland had already been reached, and they were only waiting for

the landing of the cable at the now far-distant end.

At length the light quivers, and the spot begins to move. It answers to

concerted signals. And soon the operator spells out the joyful message.

The ocean has been spanned with an electric nerve, and the New World

responds to the greetings of the Old.

Here is something practical, which all can appreciate, and all are ready

to honor. We honor the courage which conceived, the skill which

executed, and, above all, the success which crowned the undertaking. But

do we not forget that professor of Bologna, with his frogs' legs, who

sowed the seed from which all this has sprung? He labored without hope

of temporal reward, stimulated by the pure love of truth, and the grain

which he planted has brought forth this abundant harvest. Do we not

forget, also, that succession of equally noble men, Volta, and Oersted,

and Faraday, with many other not less devoted investigators of

electrical science, without whose unselfish labors the great result

never could have been achieved? Such men, of course, need no recognition

at our hands, and I ask the question not for their sakes, but for ours.

The intellectual elevation of the lives they led was their

all-sufficient reward.

It is, however, of the utmost importance for us, citizens of a country

with almost unlimited resources, that we should recognize what are the

real springs of true national greatness and enduring influence. In this

age of material interests, the hand is too ready to say to the head, "I

have no need of thee"; and, amid the ephemeral applause which follows

the realization of some triumph over matter, we are apt to be deceived,

and not observe whence the power came. We associate the great invention

with some man of affairs man who overcame the last material obstacle,

and who, although worthy of all praise, probably added very little to

the total wealth of knowledge of which the invention was an immediate

consequence; and, not seeing the antecedents, we are apt to underrate

the part which the student or scientific investigator may have

contributed to the result.

It is idle, for example, to speak of the electric telegraph as invented

by any single man. It was a growth of time, and many of the men who

contributed to win this great victory of mind over space "builded far

better than they knew." As I view the subject, that invention is as

much a gift of Providence as if the details had been supernaturally

revealed. But, whatever may be our speculative views, it is of the

utmost importance to the welfare of our community that we should realize

the fact that purely theoretical scientific study, pursued for truth's

sake, is the essential prerequisite for such inventions. Knowledge is

the condition of invention. The old Latin word _invenio_ signifies _to

meet with_, as well as to _find_, and these great gifts of God are _met

with_ along the pathway of civilization; but the throng of the world

passes them unnoticed, for only those can recognize the treasure whose

minds have been stored with the knowledge which the scholar has

discovered and made known.

If, then, as no one will deny, science and scholarship are the powers by

which improvements in the useful arts are made, I might appeal to your

self-interest to support and cherish them. But I should despise myself

for appealing to such a motive, and you for requiring it. The supreme

importance of science and scholarship to a nation does not depend in the

least on the circumstance that important practical results may follow.

When, as in the case of Galvani's frogs, they come in the order of

Providence, let us thank God for them as a gift which we had no right

either to expect or demand. Science, if studied successfully, must be

studied for the pure love of truth; and, if we serve her solely for

mercenary ends, her truths, the only gold she offers, will turn to dross

in our hands, and we shall degrade ourselves in proportion as we

dishonor her.

Galvani, and Volta, and Oersted, who discovered the truths of which the

electric telegraph is a simple application, sure to be made as soon as

the time was ripe, are not the less to be honored because they died

before the fullness of that time had come. We honor them for the truths

they discovered, and the lustre of their consecrated lives could be

neither enhanced nor impaired by subsequent events; and it is because I

am persuaded that such lives are the salt of the world, the saviours of

society, that I would lead you to cherish and sustain them; and, that I

may enforce this conclusion, allow me to ask your attention to another

historical incident, which presents a striking parallelism to the last.

I must take you back to a period which we, of a nation born but

yesterday, regard as distant, but which was one of the most noted epochs

of modern history--the age of Luther and the Reformation. I must ask you

to accompany me to the small town of Allenstein, near Frauenberg, in

Eastern Prussia, where, on May 23, 1543, there lay dying one of the

great benefactors of mankind.

This man, old at seventy years, "bent and furrowed with labor, but in

whose eye the fire of genius was still glowing," was then known as one

of the most learned men of his time. Doctor of medicine as well as of

theology, Canon of Frauenberg, Honorary Professor of Bologna and Rome,

while devoting his leisure to study, he had passed a life of active

benevolence in administering to the bodily as well as the spiritual

wants of the ignorant people among whom his lot had been cast. He was

also a great mechanical genius, and, by various labor-saving machines,

of his own invention, he had contributed greatly to the welfare of the

surrounding country.

But the superstitious peasants, although they had hitherto reverenced

the great man as their best friend and benefactor, had been recently

incited by his enemies and rivals in the church to curse him as a

heretic and a wizard. A few days back he had been the unwilling witness

of one of those out-of-door spectacles, so common at that time, in which

his scientific opinions had been travestied, his charities ridiculed,

and his devoted life made the object of slander and reproach. This

ingratitude of his flock had broken his heart, and he could not recover

from the blow.

The occasion of this outburst of fanaticism was the approaching

publication of a work in which he had dared to question the received

opinions of theologians and schoolmen, in regard to cosmogony. He had,

forsooth, denied that the visible firmament was a solid azure-colored

shell, to which the sun and planets were fastened, and through whose

opened doors the rain descended. He had proved that the sun was the

center of the system, around which the earth and planets revolved, and,

with his clear scientific vision, he had been able to gain glimpses, at

least, of the grand conceptions of modern astronomy: For this man was

Nicolas Copernicus, and the expected book was his great work--"De Orbium

Coelestium Revolutionibus"--destined to form the broad basis of

astronomical science.

The work was printing at Nuremberg, and the last proofs had been

returned; but reports had come that a similar outburst of fanaticism was

raging at that place, that a mob had burned the manuscript on the public

square, and had threatened to break the press should the printing

proceed. But, thanks to God! the old man was not to die before the hour

of triumph came. While still conscious, a horse, covered with foam,

gallops to the door of his humble dwelling, and an armed messenger

enters the chamber, who, breathless with haste, places in the hands of

the dying man a volume still wet from the press. He has only strength to

return a smile of recognition, and murmur the last words:

"Nunc dimittis servum tuum, Domine."

Grand close of a noble life! The seed has been sown--what could we

desire more?

Again the centuries roll on--not one, but three--while the seed grows to

a great tree, which overshadows the nations. Great minds have never been

wanting to cherish and prime it, like Tycho Brahe and Kepler, Galileo

and Newton, Laplace and Lagrange; and although at times some, while

lingering in the deep shade of the foliage, may have lost sight of the

summit, the noble tree has ever pointed upward to direct aspiration and

encourage hope.

On the evening of the 24th of September, 1846, in the Observatory of

Berlin, a trained astronomical observer was carefully measuring the

position of a faint star in the constellation Capricorn. Only the day

before, he had received from Le Verrier a letter announcing the result

of that remarkable investigation which has made the name of this

distinguished French astronomer so justly celebrated. By the studies of

the great men who succeeded Copernicus, his system had become so

perfected as to enable the astronomer to predict, with unerring

certainty, the paths of the planets through the heavens. But there was

one failing case. The planet Uranus, then supposed to be the outer

planet of the solar system, wandered from the path which theory assigned

to it; and although the deviations were but small, yet any discrepancy

between theory and observation in so accurate a science as astronomy

could not be overlooked.

Long before this, the hypothesis had been advanced that the deviations

were caused by the attractive force of an unseen and still more distant

planet; but, as no such planet had been discovered, the hypothesis had

remained until now wholly barren. The hypothesis, however, was

reasonable, and furnished the only conceivable explanation of the facts;

and, moreover, if true, the received system of astronomy ought to be

able to assign the position and magnitude of the disturbing body, the

magnitude and direction of the displacements being given.

This possibility was generally appreciated by astronomers, and the very

great length and difficulty of the mathematical calculation which the

investigation involved was probably the reason that no one had hitherto

undertaken it. Le Verrier, however, had both the courage and the

youthful strength required for the work. And now the great work had been

done; and, on the 18th of September, Le Verrier had sent to the

Observatory of Berlin his communication announcing the final result,

namely, that the planet would be found about 5 deg. to the east of the star

Delta of Capricorn.

The letter containing this announcement was received by Galle, at

Berlin, on the 23d, and it was Galle whom we left measuring the position

of that faint star on the evening of the 24th. It so happened that a

chart of that portion of the heavens had recently been prepared by the

Berlin Observatory, and was on the eve of publication; and, on the very

evening he received the letter, Galle had found, near the position

assigned by Le Verrier, a faint star, which was not marked on this

chart. The object differed in appearance from the surrounding stars, but

still it was perfectly possible that it might be a fixed star which had

escaped previous observation.

But, if a fixed star, its position in the constellation would not vary,

while, if a planet, a single night would show a perceptible change of

place. Hence, you may conceive of the interest with which Galle was

measuring anew its position on the evening of the 24th.

The star had moved, and in the direction which theory indicated; and for

once, at least, the world rang with applause at a brilliant scientific

conquest from which there was not one cent of money to be made. Yet, was

that conquest any less important to the world? What had it secured? It

had confirmed the theory of astronomy which Copernicus and his

successors had built up, and it had clinched the last nail in the proof

that those grand conceptions of modern astronomy, now household

thoughts, are realities, and not dreams. Certainly no military conquest

can compare with this.

Do not smile at the enthusiasm which rates so high a purely intellectual

achievement? Go out with me under the heavens, in some starlight night,

and, looking up into the depths of space, recall the truths you have

learned in regard to that immensity, and allow the imagination free

scope as it stretches out into the infinitudes of time, space, and

power, carrying the mind on, bound by bound, through the limitless

expanse, until even the imagination refuses to follow, and fairly quails

before the mighty form of the Infinite, which rises to confront it!

Remember now that your forefathers, of only a few centuries back, saw

there nothing but a solid dome hemming in the earth and skies, and that

you are able to look upon this grand spectacle only because great minds

have lived who have opened your intellectual eyes; and then answer me,

is not this result worth all the labor, all the sacrifice, all the

treasure it has cost?

Every educated man, who has not sold his birthright for a mess of

pottage, lives a grander and nobler life, because the great astronomers

have thought and taught, and this elevation of human life is the

greatest achievement of which man can boast. Before it all material

conquests appear of little worth, and the lustre of all military or

civil glory grows dim. Cherish this intellectual life; foster it;

sustain it; do what you can by your own spirit and influence, and, if

you are blessed with riches, give of your abundance to support and

encourage those who, by genius, talent, and devotion, will widen the

intellectual kingdom. Be assured you will thus help to confer an

inestimable boon on your race and on your country; and the influence for

good will not be felt by the intellectual life of the nation only. That

corruption which is now festering at the heart of our body politic, and

threatening its destruction, can in no way be fought and conquered so

effectually as by keeping constantly before the nation noble and high

ideals; for, where the higher life is cherished and honored, the

mercenary and sensual motives of action, which both invite and shield

corruption, lose much of their force and power.

But you may tell me that there is a life higher than the intellectual

life, and that I have ascribed to science and scholarship influences

which come only from a source which I have forgotten, or left out of

view. My friends, all truth is one and inseparable, and I have therefore

made no distinction in this address between the truths of science and

truths of religion. The grand old word knowledge, as I have used it,

includes both, and, in just the proportion that you reverence religion,

you must reverence also true science. All truth is God's truth, and, in

praying for the coming of his kingdom, you certainly do not expect that

Nature will be divorced from Grace. If the truths of religion required a

special revelation, it must be expected that they would transcend human

intelligence. These very conditions imply conflict, but the conflict

comes not from the knowledge, but from the ignorance and conceit of men;

and the only proper attitude for the devout scholar is "to labor and to

wait." And what more wonderful confirmation could we have of the

essential unity of the two phases of truth than is to be found in the

fact that the characteristic of science, which I have been endeavoring

to illustrate in this address, is the great prominent feature of

Christianity? Christianity was revealed in a life, and ever abides a

life in the soul of man, to purify, ennoble, and redeem humanity.

"And so the Word had breath, and wrought,

With human hands, the creed of creeds,

In loveliness of perfect deeds,

More strong than all poetic thought--

"Which he may read that binds the sheaf,

Or builds the house, or digs the grave,

And those wild eyes that watch the wave,

In roarings round the coral reef."
