which has mined the ground under selfconfident liberalism of the last thirty years, and has prepared the way for its sudden collapse and suppression? It is in this manner that the sentiment of Oxford for beauty and sweetness conquers, and in this manner long may it continue to conquer!

In this manner it works to the same end as culture, and there is plenty of work for it yet to do. I have said that the new and more democratic force which is now superseding our old middle-class liberalism cannot yet be rightly judged. It has its main tendencies still to form. We hear promises of its giving us administrative reform, law reform, reform of education, and I know not what; but those promises come rather from its advocates, wishing to make a good plea for it and to justify it for superseding middle-class liberalism, than from clear tendencies which it has itself yet developed. But meanwhile it has plenty of well-intentioned friends against whom culture may with advantage continue to uphold steadily its ideal of human perfection; that this is an inward spiritual activity, having for its characters increased sweetness, increased light, increased life, increased sympathy. Mr. Bright, who has a foot in both worlds, the world of middle-class liberalism and the world of democracy, but who brings most of his ideas from the world of middleclass liberalism in which he was bred, always inclines to inculcate that faith in machinery to which, as we have seen, Englishmen are so prone, and which has been the bane of middle-class liberalism. He complains with a sorrowful indignation of people who "appear to have no proper estimate of the value of the franchise"; he leads his disciples to believe what the Englishman is always too ready to believe that the having a vote, like the having a large family, or a large business, or large muscles, has in itself some edifying and perfecting effect upon human nature. Or else he cries out to the democracy,-"the men," as he calls them, "upon whose shoulders the greatness of England rests," he cries out to them: "See what you have done! I look over this country and see the cities you have built, the railroads you have made, the manufactures you have produced, the cargoes which freight the ships of the greatest mercantile navy the world has ever seen! I see that you have converted by your labors what was a wilderness, these islands, into a

once

fruitful garden; I know that you have created this wealth, and are a nation whose name is a word of power throughout all the world." Why, this is just the very style of laudation with which Mr. Roebuck or Mr. Lowe debauches the minds of the middle classes, and makes such Philistines of them. It is the same fashion of teaching a man to value himself not on what he is, not on his progress in sweetness and light, but on the number of the railroads he has constructed, or the bigness of the tabernacle he has built. Only the middle classes are told they have done it all with their energy, self-reliance, and capital, and the democracy are told they have done it all with their hands and sinews. But teaching the democracy to put its trust in achievements of this kind is merely training them to be Philistines to take the place of the Philistines whom they are superseding; and they, too, like the middle class, will be encouraged to sit down at the banquet of the future without having on a wedding garment, and nothing excellent can then come from them. Those who know their besetting faults, those who have watched them and listened to them, or those who will read the instructive account recently given of them by one of themselves, the Journeyman Engineer, will agree that the idea which culture sets before us of perfection,-an increased spiritual activity, having for its characters. increased sweetness, increased light, increased life, increased sympathy, is an idea which the new democracy needs far more than the idea of the blessedness of the franchise, or the wonderfulness of its own industrial performances.

Other well-meaning friends of this new power are for leading it, not in the old ruts of middle-class Philistinism, but in ways which are naturally alluring to the feet of democracy, though in this country they are novel and untried ways. I may call them the ways of Jacobinism. Violent indignation with the past, abstract systems of renovation applied wholesale, a new doctrine drawn up in black and white for elaborating down to the very smallest details a rational society for the future,these are the ways of Jacobinism. Mr. Frederic Harrison and other disciples of Comte, one of them, Mr. Congreve, is an old friend of mine, and I am glad to have an opportunity of publicly expressing my respect for his talents and character,—are

among the friends of democracy who are for leading it in paths of this kind. Mr. Frederic Harrison is very hostile to culture, and from a natural enough motive; for culture is the eternal opponent of the two things which are the signal marks of Jacobinism,— its fierceness, and its addiction to an abstract system. Culture is always assigning to system-makers and systems a smaller share in the bent of human destiny than their friends like. A current in people's minds sets towards new ideas; people are dissatisfied with their old narrow stock of Philistine ideas, Anglo-Saxon ideas, or any other; and some man, some Bentham or Comte, who has the real merit of having early and strongly felt and helped the new current, but who brings plenty of narrowness and mistakes of his own into his feeling and help of it, is credited with being the author of the whole current, the fit person to be entrusted with its regulation and to guide the human race.

The excellent German historian of the mythology of Rome, Preller, relating the introduction at Rome under the Tarquins of the worship of Apollo, the god of light, healing, and reconciliation, will have us observe that it was not so much the Tarquins who brought to Rome the new worship of Apollo, as a current in the mind of the Roman people which set powerfully at that time towards a new worship of this kind, and away from the old run of Latin and Sabine religious ideas. In a similar way, culture directs our attention to the natural current there is in human affairs, and to its continual working, and will not let us rivet our faith upon any one man and his doings. It makes us see not only his good side, but also how much in him was of necessity limited and transient; nay, it even feels a pleasure, a sense of an increased freedom and of an ampler future, in so doing.

I remember, when I was under the influence of a mind to which I feel the greatest obligations, the mind of a man who was the very incarnation of sanity and clear sense, a man the most considerable, it seems to me, whom America has yet produced,Benjamin Franklin,-I remember the relief with which, after long feeling the sway of Franklin's imperturbable common-sense, I came upon a project of his for a new version of the Book of Job, to replace the old version, the style of which, says Franklin,

has become obsolete, and thence less agreeable. "I give," he continues, “a few verses, which may serve as a sample of the kind of version I would recommend." We all recollect the famous verse in our translation: "Then Satan answered the Lord and said: 'Doth Job fear God for nought?'" Franklin makes this: "Does your Majesty imagine that Job's good conduct is the effect of mere personal attachment and affection?" I well remember how, when first I read that, I drew a deep breath of relief and said to myself: "After all, there is a stretch of humanity beyond Franklin's victorious good sense!" So, after hearing Bentham cried loudly up as the renovator of modern society, and Bentham's mind and ideas proposed as the rulers of our future, I open the Deontology. There I read: "While Xenophon was writing his history and Euclid teaching geometry, Socrates and Plato were talking nonsense under pretense of talking wisdom and morality. This morality, of theirs consisted in words; this wisdom of theirs was the denial of matters known to every man's experience." From the moment of reading that, I am delivered from the bondage of Bentham! the fanaticism of his adherents can touch me no longer. I feel the inadequacy of his mind and ideas for supplying the rule of human society, for perfection.

Culture tends always thus to deal with the men of a system, of disciples, of a school; with men like Comte, or the late Mr. Buckle, or Mr. Mill. However much it may find to admire in these personages, or in some of them, it nevertheless remembers the text: "Be not ye called Rabbi!" and it soon passes on from any Rabbi. But Jacobinism loves a Rabbi; it does not want to pass on from its Rabbi in pursuit of a future and still unreached perfection; it wants its Rabbi and his ideas to stand for perfection, that they may with the more authority recast the world; and for Jacobinism, therefore, culture, eternally passing onwards and seeking, is an impertinence and an offence. But culture, just because it resists this tendency of Jacobinism to impose on us a man with limitations and errors of his own along with the true ideas of which he is the organ, really does the world and Jacobinism itself a service.

So, too, Jacobinism, in its fierce hatred of the past and of those whom it makes liable for the sins of the past, cannot away

with the inexhaustible indulgence proper to culture, the consideration of circumstances, the severe judgment of actions joined to the merciful judgment of persons. "The man of culture is in politics," cries Mr. Frederic Harrison, "one of the poorest mortals alive!" Mr. Frederic Harrison wants to be doing business, and he complains that the man of culture stops him with a "turn for small fault-finding, love of selfish ease, and indecision in action." Of what use is culture, he asks, except for "a critic of new books or a professor of belles-lettres?" Why, it is of use because, in presence of the fierce exasperation which breathes, or rather, I may say, hisses through the whole production in which Mr. Frederic Harrison asks that question, it reminds us that the perfection of human nature is sweetness and light. It is of use, because, like religion,-that other effort after perfection,-it testifies that, where bitter envying and strife are, there is confusion and every evil work.

The pursuit of perfection, then, is the pursuit of sweetness and light. He who works for sweetness and light, works to make reason and the will of God prevail. He who works for machinery, he who works for hatred, works only for confusion. Culture looks beyond machinery, culture hates hatred; culture has one great passion, the passion for sweetness and light. It has one even yet greater!-the passion for making them prevail. It is not satisfied till we all come to a perfect man; it knows that the sweetness and light of the few must be imperfect until the raw and unkindled masses of humanity are touched with sweetness and light. If I have not shrunk from saying that we must work for sweetness and light, so neither have I shrunk from saying that we must have a broad basis, must have sweetness and light for as many as possible. Again and again I have insisted how those are the happy moments of humanity, how those are the marking epochs of a people's life, how those are the flowering times for literature and art and all the creative power of genius, when there is a national glow of life and thought, when the whole of society is in the fullest measure permeated by thought, sensible to beauty, intelligent and alive. Only it must be real thought and real beauty; real sweetness and real light. Plenty of people will try to give the masses, as they call them, an intellectual food pre

pared and adapted in the way they think proper for the actual condition of the masses. The ordinary popular literature is an example of this way of working on the masses. Plenty of people will try to indoctrinate the masses with the set of ideas and judgments constituting the creed of their own profession or party. Our religious and political organizations give an example of this way of working on the masses. I condemn neither way; but culture works differently. It does not try to teach down to the level of inferior classes; it does not try to win them for this or that sect of its own, with ready-made judgments and watchwords. It seeks to do away with classes; to make the best that has been thought and known in the world current everywhere; to make all men live in an atmosphere of sweetness and light, where they may use ideas, as it uses them itself, freely, nourished, and not bound by them.

This is the social idea; and the men of culture are the true apostles of equality. The great men of culture are those who have had a passion for diffusing, for making prevail, for carrying from one end of society to the other, the best knowledge, the best ideas of their time; who have labored to divest knowledge of all that was harsh, uncouth, difficult, abstract, professional, exclusive; to humanize it, to make it efficient outside the clique of the cultivated and learned, yet still remaining the best knowledge and thought of the time, and a true source, therefore, of sweetness and light. Such a man was Abelard in the Middle Ages, in spite of all his imperfections; and thence the boundless emotion and enthusiasm which Abelard excited. Such were Lessing and Herder in Germany, at the end of the last century; and their services to Germany were in this way inestimably precious. Generations will pass, and literary monuments will accumulate, and works far more perfect than the works of Lessing and Herder will be produced in Germany; and yet the names of these two men will fill a German with a reverence and enthusiasm such as the names of the most gifted masters will hardly awaken. And why? Because they humanized knowledge; because they broadened the basis of life and intelligence; because they worked powerfully to diffuse sweetness and light, to make reason and the will of God prevail. With Saint Augustine they said: "Let us not leave thee alone to make in the

secret of thy knowledge, as thou didst before the creation of the firmament, the division of light from darkness; let the children of thy spirit, placed in their firmament, make their light shine upon the earth, mark the division of night and day, and announce the revolution of the times; for the old order

is passed, and the new arises; the night is spent, the day is come forth; and thou shalt crown the year with thy blessing, when thou shalt send forth laborers into thy harvest sown by other hands than theirs; when thou shalt send forth new laborers to new seedtimes, whereof the harvest shall be not yet."

THE PHYSICAL BASIS OF LIFE

THOMAS HENRY HUXLEY

[From an address delivered in Edinburgh in 1868; and published in "Lay Sermons," 1870.]

In order to make the title of this discourse generally intelligible, I have translated the term "Protoplasm," which is the scientific name of the substance of which I am about to speak, by the words "the physical basis of life." I suppose that, to many, the idea that there is such a thing as a physical basis, or matter, of life may be novelso widely spread is the conception of life as a something which works through matter, but is independent of it; and even those who are aware that matter and life are inseparably connected, may not be prepared for the conclusion plainly suggested by the phrase, "the physical basis or matter of life," that there is some one kind of matter which is common to all living beings, and that their endless diversities are bound together by a physical, as well as an ideal, unity. In fact, when first apprehended, such a doctrine as this appears almost shocking to common

sense.

What, truly, can seem to be more obviously different from one another, in faculty, in form, and in substance, than the various kinds of living beings? What community of faculty can there be between the brightlycolored lichen, which so nearly resembles a mere mineral incrustation of the bare rock on which it grows, and the painter, to whom it is instinct with beauty, or the botanist, whom it feeds with knowledge?

Again, think of the microscopic fungusa mere infinitesimal ovoid particle, which finds space and duration enough to multiply into countless millions in the body of a liv

ing fly; and then of the wealth of foliage, the luxuriance of flower and fruit, which lies between this bald sketch of a plant and the giant pine of California, towering to the dimensions of a cathedral spire, or the Indian fig, which covers acres with its profound shadow, and endures while nations and empires come and go around its vast circumference. Or, turning to the other half of the world of life, picture to yourselves the great Finner whale, hugest of beasts that live, or have lived, disporting his eighty or ninety feet of bone, muscle, and blubber, with easy roll, among waves in which the stoutest ship that ever left dockyard would flounder hopelessly; and contrast him with the invisible animalcules-mere gelatinous specks, multitudes of which could, in fact, dance upon the point of a needle with the same ease as the angels of the Schoolmen could, in imagination. With these images. before your minds, you may well ask, what community of form, or structure, is there between the animalcule and the whale; or between the fungus and the fig-tree? And, à fortiori, between all four?

Finally, if we regard substance, or material composition, what hidden bond can connect the flower which a girl wears in her hair and the blood which courses through her youthful veins; or, what is there in common between the dense and resisting mass of the oak, or the strong fabric of the tortoise, and those broad disks of glassy jelly which may be seen pulsating through the waters of a calm sea, but which drain away to mere films in the hand which raises them out of their element?

Such objections as these must, I think, arise in the mind of every one who ponders. for the first time, upon the conception of a single physical basis of life underlying all the diversities of vital existence; but I pro

pose to demonstrate to you that, notwithstanding these apparent difficulties, a threefold unity—namely, a unity of power or faculty, a unity of form, and a unity of substantial composition-does pervade the whole living world.

No very abstruse argumentation is needed, in the first place, to prove that the powers, or faculties, of all kinds of living matter, diverse as they may be in degree, are substantially similar in kind.

Goethe has condensed a survey of all powers of mankind into the well-known epigram:

"Warum treibt sich das Volk so und schreit? Es will sich ernähren, Kinder zeugen, und die nähren so gut es vermag.

Weiter bringt es kein Mensch, stell' er sich wie er auch will." 1

In physiological language this means, that all the multifarious and complicated activities of man are comprehensible under three categories. Either they are immediately directed towards the maintenance and development of the body, or they effect transitory changes in the relative positions of parts of the body, or they tend towards the continuance of the species. Even those manifestations of intellect, of feeling, and of will, which we rightly name the higher faculties, are not excluded from this classification, inasmuch as to every one but the subject of them, they are known only as transitory changes in the relative positions of parts of the body. Speech, gesture, and every other form of human action are, in the long run, resolvable into muscular contraction, and muscular contraction is but a transitory change in the relative positions of the parts of a muscle. But the scheme which is large

enough to embrace the activities of the high

est form of life, covers all those of the lower creatures. The lowest plant, or animalcule, feeds, grows, and reproduces its kind. In addition, all animals manifest those transitory changes of form which we class under irritability and contractility; and it is more than probable that when the vegetable world is thoroughly explored, we shall find all plants in possession of the same powers, at

one time or other of their existence. I am not now alluding to such phenomena, at once rare and conspicuous, as those exhibited by the leaflets of the sensitive plants, or the stamens of the barberry, but to much more widely spread, and at the same time, more subtle and hidden, manifestations of vegetable contractility. You are doubtless aware that the common nettle owes its stinging property to the innumerable stiff and needle-like, though exquisitely delicate, hairs which cover its surface. Each stingingneedle tapers from a broad base to a slender summit, which, though rounded at the end, is of such microscopic fineness that it readily penetrates, and breaks off in, the skin. The whole hair consists of a very delicate outer case of wood, closely applied to the inner surface of which is a layer of semifluid matter, full of innumerable granules of extreme minuteness. This semi-fluid lining is protoplasm, which thus constitutes a kind of bag, full of a limpid liquid, and roughly corresponding in form with the interior of the hair which it fills. When viewed with a sufficiently high magnifying power, the protoplasmic layer of the nettle hair is seen to be in a condition of unceasing activity. Local contractions of the whole thickness of its substance pass slowly and gradually from point to point, and give rise to the appearance of progressive waves, just as the bending of successive stalks of corn by a breeze produces the apparent billows of a corn-field.

But, in addition to these movements, and independently of them, the granules are driven, in relatively rapid streams, through channels in the protoplasm which seem to have a considerable amount of persistence. Most commonly, the currents in adjacent tions; and, thus, there is a general stream parts of the protoplasm take similar direcup one side of the hair and down the other. But this does not prevent the existence of

partial currents which take different routes; and sometimes trains of granules may be seen coursing swiftly in opposite directions within a twenty-thousandth of an inch of one another; while, occasionally, opposite streams come into direct collision, and, after a longer or shorter struggle, one predominates. The cause of these currents seems to lie in contractions of the protoplasm which bounds the channels in which they flow, but which are so minute that the best microscopes show only their effects, and not themselves.
