Of that life, energy, will, or wine,--whatever the poets or professors called it,--G.o.d was the only cause, as He was also the immediate cause, and support. Thomas was emphatic on that point. G.o.d is the cause of energy as the sun is the cause of colour: "prout sol dicitur causa manifestationis coloris." He not only gives forms to his pipkins, or energies to his agents, but He also maintains those forms in being: "dat formas creaturis agentibus et eas tenet in esse." He acts directly, not through secondary causes, on everything and every one: "Deus in omnibus intime operatur." If, for an instant, G.o.d's action, which is also His will, were to stop, the universe would not merely fall to pieces, but would vanish, and must then be created anew from nothing: "Quia non habet radicem in aere, statim cessat lumen, cessante actione solis. Sic autem se habet omnis creatura ad Deum sicut aer ad solem illuminantem." G.o.d radiates energy as the sun radiates light, and "the whole fabric of nature would return to nothing" if that radiation ceased even for an instant. Everything is created by one instantaneous, eternal, universal act of will, and by the same act is maintained in being.

Where, then,--in what mysterious cave outside of creation,--could man, and his free will, and his private world of responsibilities and duties, lie hidden? Unless man was a free agent in a world of his own beyond constraint, the Church was a fraud, and it helped little to add that the State was another. If G.o.d was the sole and immediate cause and support of everything in His creation, G.o.d was also the cause of its defects, and could not--being Justice and Goodness in essence--hold man responsible for His own omissions.

Still less could the State or Church do it in His name.

Whatever truth lies in the charge that the schools discussed futile questions by faulty methods, one cannot decently deny that in this case the question was practical and the method vital. Theist or atheist, monist or anarchist must all admit that society and science are equally interested with theology in deciding whether the universe is one or many, a harmony or a discord. The Church and State a.s.serted that it was a harmony, and that they were its representatives. They say so still. Their claim led to singular but unavoidable conclusions, with which society has struggled for seven hundred years, and is still struggling.

Freedom could not exist in nature, or even in G.o.d, after the single, unalterable act or will which created. The only possible free will was that of G.o.d before the act. Abelard with his rigid logic averred that G.o.d had no freedom; being Himself whatever is most perfect, He produced necessarily the most perfect possible world. Nothing seemed more logical, but if G.o.d acted necessarily, His world must also be of necessity the only possible product of His act, and the Church became an impertinence, since man proved only fatuity by attempting to interfere. Thomas dared not disturb the foundations of the Church, and therefore began by laying down the law that G.o.d-- previous to His act--could choose, and had chosen, whatever scheme of creation He pleased, and that the harmony of the actual scheme proved His perfections. Thus he saved G.o.d's free will.

This philosophical apse would have closed the lines and finished the plan of his church-choir had the universe not shown some divergencies or discords needing to be explained. The student of the Latin Quarter was then harder to convince than now that G.o.d was Infinite Love and His world a perfect harmony, when perfect love and harmony showed them, even in the Latin Quarter, and still more in revealed truth, a picture of suffering, sorrow, and death; plague, pestilence, and famine; inundations, droughts, and frosts; catastrophes world-wide and accidents in corners; cruelty, perversity, stupidity, uncertainty, insanity; virtue begetting vice; vice working for good; happiness without sense, selfishness without gain, misery without cause, and horrors undefined. The students in public dared not ask, as Voltaire did, "avec son hideux sourire,"

whether the Lisbon earthquake was the final proof of G.o.d's infinite goodness, but in private they used the argumentum ad personam divinam freely enough, and when the Church told them that evil did not exist, the ribalds laughed.

Saint Augustine certainly tempted Satan when he fastened the Church to this doctrine that evil is only the privation of good, an amiss...o...b..ni; and that good alone exists. The point was infinitely troublesome. Good was order, law, unity. Evil was disorder, anarchy, multiplicity. Which was truth? The Church had committed itself to the dogma that order and unity were the ultimate truth, and that the anarchist should be burned. She could do nothing else, and society supported her--still supports her; yet the Church, who was wiser than the State, had always seen that Saint Augustine dealt with only half the question. She knew that evil might be an excess of good as well as absence of it; that good leads to evil, evil to good; and that, as Pascal says, "three degrees of polar elevation upset all jurisprudence; a meridian decides truth; fundamental laws change; rights have epochs. Pleasing Justice! bounded by a river or a mountain! truths on this side the Pyrenees! errors beyond!" Thomas conceded that G.o.d Himself, with the best intentions, might be the source of evil, and pleaded only that his action might in the end work benefits. He could offer no proof of it, but he could a.s.sume as probable a plan of good which became the more perfect for the very reason that it allowed great liberty in detail.

One hardly feels Saint Thomas here in all his force. He offers suggestion rather than proof;--apology--the weaker because of obvious effort to apologize--rather than defence, for Infinite Goodness, Justice, and Power; scoffers might add that he invented a new proof ab defectu, or argument for proving the perfection of a machine by the number of its imperfections; but at all events, society has never done better by way of proving its right to enforce morals or unity of opinion. Unless it a.s.serts law, it can only a.s.sert force. Rigid theology went much further. In G.o.d's providence, man was as nothing. With a proper sense of duty, every solar system should be content to suffer, if thereby the efficiency of the Milky Way were improved. Such theology shocked Saint Thomas, who never wholly abandoned man in order to exalt G.o.d. He persistently brought G.o.d and man together, and if he erred, the Church rightly pardons him because he erred on the human side. Whenever the path lay through the valley of despair he called G.o.d to his aid, as though he felt the moral obligation of the Creator to help His creation.

At best the vision of G.o.d, sitting forever at His work-table, willing the existence of mankind exactly as it is, while conscious that, among these myriad arbitrary creations of His will, hardly one in a million could escape temporary misery or eternal d.a.m.nation, was not the best possible background for a Church, as the Virgin and the Saviour frankly admitted by taking the foreground; but the Church was not responsible for it. Mankind could not admit an anarchical--a dual or a multiple--universe. The world was there, staring them in the face, with all its chaotic conditions, and society insisted on its unity in self-defence. Society still insists on treating it as unity, though no longer affecting logic. Society insists on its free will, although free will has never been explained to the satisfaction of any but those who much wish to be satisfied, and although the words in any common sense implied not unity but duality in creation. The Church had nothing to do with inventing this riddle--the oldest that fretted mankind.

Apart from all theological interferences,--fall of Adam or fault of Eve, Atonement, Justification, or Redemption,--either the universe was one, or it was two, or it was many; either energy was one, seen only in powers of itself, or it was several; either G.o.d was harmony, or He was discord. With practical unanimity, mankind rejected the dual or multiple scheme; it insisted on unity. Thomas took the question as it was given him. The unity was full of defects; he did not deny them; but he claimed that they might be incidents, and that the admitted unity might even prove their beneficence. Granting this enormous concession, he still needed a means of bringing into the system one element which vehemently refused to be brought:--that is, man himself, who insisted that the universe was a unit, but that he was a universe; that energy was one, but that he was another energy; that G.o.d was omnipotent, but that man was free. The contradiction had always existed, exists still, and always must exist, unless man either admits that he is a machine, or agrees that anarchy and chaos are the habit of nature, and law and order its accident. The agreement may become possible, but it was not possible in the thirteenth century nor is it now. Saint Thomas's settlement could not be a simple one or final, except for practical use, but it served, and it holds good still.

No one ever seriously affirmed the literal freedom of will. Absolute liberty is absence of restraint; responsibility is restraint; therefore, the ideally free individual is responsible only to himself. This principle is the philosophical foundation of anarchism, and, for anything that science has yet proved, may be the philosophical foundation of the universe; but it is fatal to all society and is especially hostile to the State. Perhaps the Church of the thirteenth century might have found a way to use even this principle for a good purpose; certainly, the influence of Saint Bernard was sufficiently unsocial and that of Saint Francis was sufficiently unselfish to conciliate even anarchists of the militant cla.s.s; but Saint Thomas was working for the Church and the

State, not for the salvation of souls, and his chief object was to repress anarchy. The theory of absolute free will never entered his mind, more than the theory of material free will would enter the mind of an architect. The Church gave him no warrant for discussing the subject in such a sense. In fact, the Church never admitted free will, or used the word when it could be avoided. In Latin, the term used was "liberum arbitrium,"--free choice,--and in French to this day it remains in strictness "libre arbitre" still. From Saint Augustine downwards the Church was never so unscientific as to admit of liberty beyond the faculty of choosing between paths, some leading through the Church and some not, but all leading to the next world; as a criminal might be allowed the liberty of choosing between the guillotine and the gallows, without infringing on the supremacy of the judge.

Thomas started from that point, already far from theoretic freedom.

"We are masters of our acts," he began, "in the sense that we can choose such and such a thing; now, we have not to choose our end, but the means that relate to it, as Aristotle says." Unfortunately, even this trenchant amputation of man's free energies would not accord with fact or with logic. Experience proved that man's power of choice in action was very far from absolute, and logic seemed to require that every choice should have some predetermining cause which decided the will to act. Science affirmed that choice was not free,--could not be free,--without abandoning the unity of force and the foundation of law. Society insisted that its choice must be left free, whatever became of science or unity. Saint Thomas was required to ill.u.s.trate the theory of "liberum arbitrium" by choosing a path through these difficulties, where path there was obviously none.

Thomas's method of treating this problem was sure to be as scientific as the vaulting of a Gothic arch. Indeed, one follows it most easily by translating his school-vocabulary into modern technical terms. With very slight straining of equivalents, Thomas might now be written thus:--

By the term G.o.d, is meant a prime motor which supplies all energy to the universe, and acts directly on man as well as on all other creatures, moving him as a mechanical motor might do; but man, being specially provided with an organism more complex than the organisms of other creatures, enjoys an exceptional capacity for reflex action,--a power of reflection,--which enables him within certain limits to choose between paths; and this singular capacity is called free choice or free will. Of course, the reflection is not choice, and though a man's mind reflected as perfectly as the facets of a lighthouse lantern, it would never reach a choice without an energy which impels it to act.

Now let us read Saint Thomas:--

Some kind of an agent is required to determine one's choice; that agent is reflection. Man reflects, then, in order to learn what choice to make between the two acts which offer themselves. But reflection is, in its turn, a faculty of doing opposite things, for we can reflect or not reflect; and we are no further forward than before. One cannot carry back this process infinitely, for in that case one would never decide. The fixed point is not in man, since we meet in him, as a being apart by himself, only the alternative faculties; we must, therefore, recur to the intervention of an exterior agent who shall impress on our will a movement capable of putting an end to its hesitations:--That exterior agent is nothing else than G.o.d!

The scheme seems to differ little, and unwillingly, from a system of dynamics as modern as the dynamo. Even in the prime motor, from the moment of action, freedom of will vanished. Creation was not successive; it was one instantaneous thought and act, identical with the will, and was complete and unchangeable from end to end, including time as one of its functions. Thomas was as clear as possible on that point:--"Supposing G.o.d wills anything in effect; He cannot will not to will it, because His will cannot change." He wills that some things shall be contingent and others necessary, but He wills in the same act that the contingency shall be necessary.

"They are contingent because G.o.d has willed them to be so, and with this object has subjected them to causes which are so." In the same way He wills that His creation shall develop itself in time and s.p.a.ce and sequence, but He creates these conditions as well as the events. He creates the whole, in one act, complete, unchangeable, and it is then unfolded like a rolling panorama, with its predetermined contingencies.

Man's free choice--liberum arbitrium--falls easily into place as a predetermined contingency. G.o.d is the first cause, and acts in all secondary causes directly; but while He acts mechanically on the rest of creation,--as far as is known,--He acts freely at one point, and this free action remains free as far as it extends on that line.

Man's freedom derives from this source, but it is simply apparent, as far as he is a cause; it is a reflex action determined by a new agency of the first cause.

However abstruse these ideas may once have sounded, they are far from seeming difficult in comparison with modern theories of energy.

Indeed, measured by that standard, the only striking feature of Saint Thomas's motor is its simplicity. Thomas's prime motor was very powerful, and its lines of energy were infinite. Among these infinite lines, a certain group ran to the human race, and, as long as the conduction was perfect, each man acted mechanically. In cases where the current, for any reason, was for a moment checked,--that is to say, produced the effect of hesitation or reflection in the mind,--the current acc.u.mulated until it acquired power to leap the obstacle. As Saint Thomas expressed it, the Prime Motor, Who was nothing else than G.o.d, intervened to decide the channel of the current. The only difference between man and a vegetable was the reflex action of the complicated mirror which was called mind, and the mark of mind was reflective absorption or choice. The apparent freedom was an illusion arising from the extreme delicacy of the machine, but the motive power was in fact the same--that of G.o.d.

This exclusion of what men commonly called freedom was carried still further in the process of explaining dogma. Supposing the conduction to be insufficient for a given purpose; a purpose which shall require perfect conduction? Under ordinary circ.u.mstances, in ninety-nine cases out of a hundred, the conductor will be burned out, so to speak; condemned, and thrown away. This is the case with most human beings. Yet there are cases where the conductor is capable of receiving an increase of energy from the prime motor, which enables it to attain the object aimed at. In dogma, this store of reserved energy is technically called Grace. In the strict, theological sense of the word, as it is used by Saint Thomas, the exact, literal meaning of Grace is "a motion which the Prime Motor, as a supernatural cause, produces in the soul, perfecting free will." It is a reserved energy, which comes to aid and reinforce the normal energy of the battery.

To religious minds this scientific inversion of solemn truths seems, and is, sacrilege; but Thomas's numerous critics in the Church have always brought precisely this charge against his doctrine, and are doing so still. They insist that he has reduced G.o.d to a mechanism and man to a pa.s.sive conductor of force. He has left, they say, nothing but G.o.d in the universe. The terrible word which annihilates all other philosophical systems against which it is hurled, has been hurled freely against his for six hundred years and more, without visibly affecting the Church; and yet its propriety seems, to the vulgar, beyond reasonable cavil. To Father de Regnon, of the extremely learned and intelligent Society of Jesus, the difference between pantheism and Thomism reduces itself to this: "Pantheism, starting from the notion of an infinite substance which is the plenitude of being, concludes that there can exist no other beings than THE being; no other realities than the absolute reality.

Thomism, starting from the efficacy of the first cause, tends to reduce more and more the efficacy of second causes, and to replace it by a pa.s.sivity which receives without producing, which is determined without determining." To students of architecture, who know equally little about pantheism and about Thomism,--or, indeed, for that matter, about architecture, too,--the quality that rouses most surprise in Thomism is its astonishingly scientific method. The Franciscans and the Jesuits call it pantheism, but science, too, is pantheism, or has till very recently been wholly pantheistic.

Avowedly science has aimed at nothing but the reduction of multiplicity to unity, and has excommunicated, as though it were itself a Church, any one who doubted or disputed its object, its method, or its results. The effort is as evident and quite as laborious in modern science, starting as it does from multiplicity, as in Thomas Aquinas, who started from unity; and it is necessarily less successful, for its true aims, as far as it is science and not disguised religion, were equally attained by reaching infinite complexity; but the a.s.sertion or a.s.sumption of ultimate unity has characterized the Law of Energy as emphatically as it has characterized the definition of G.o.d in theology. If it is a reproach to Saint Thomas, it is equally a reproach to Clerk-Maxwell. In truth, it is what men most admire in both--the power of broad and lofty generalization.

Under any conceivable system the process of getting G.o.d and man under the same roof--of bringing two independent energies under the same control--required a painful effort, as science has much cause to know. No doubt, many good Christians and some heretics have been shocked at the tour de force by which they felt themselves suddenly seized, bound hand and foot, attached to each other, and dragged into the Church, without consent or consultation. To religious mystics, whose scepticism concerned chiefly themselves and their own existence, Saint Thomas's man seemed hardly worth herding, at so much expense and trouble, into a Church where he was not eager to go. True religion felt the nearness of G.o.d without caring to see the mechanism. Mystics like Saint Bernard, Saint Francis, Saint Bonaventure, or Pascal had a right to make this objection, since they got into the Church, so to speak, by breaking through the windows; but society at large accepted and retains Saint Thomas's man much as Saint Thomas delivered him to the Government; a two- sided being, free or unfree, responsible or irresponsible, an energy or a victim of energy, moved by choice or moved by compulsion, as the interests of society seemed for the moment to need. Certainly Saint Thomas lavished no excess of liberty on the man he created, but still he was more generous than the State has ever been. Saint Thomas asked little from man, and gave much; even as much freedom of will as the State gave or now gives; he added immortality hereafter and eternal happiness under reasonable restraints; his G.o.d watched over man's temporal welfare far more anxiously than the State has ever done, and a.s.signed him s.p.a.ce in the Church which he never can have in the galleries of Parliament or Congress; more than all this, Saint Thomas and his G.o.d placed man in the centre of the universe, and made the sun and the stars for his uses. No statute law ever did as much for man, and no social reform ever will try to do it; yet man bitterly complained that he had not his rights, and even in the Church is still complaining, because Saint Thomas set a limit, more or less vague, to what the man was obstinate in calling his freedom of will.

Thus Saint Thomas completed his work, keeping his converging lines clear and pure throughout, and bringing them together, unbroken, in the curves that gave unity to his plan. His sense of scale and proportion was that of the great architects of his age. One might go on studying it for a lifetime. He showed no more hesitation in keeping his Deity in scale than in adjusting man to it. Strange as it sounds, although man thought himself hardly treated in respect to freedom, yet, if freedom meant superiority, man was in action much the superior of G.o.d, Whose freedom suffered, from Saint Thomas, under restraints that man never would have tolerated. Saint Thomas did not allow G.o.d even an undetermined will; He was pure Act, and as such He could not change. Man alone was allowed, in act, to change direction. What was more curious still, man might absolutely prove his freedom by refusing to move at all; if he did not like his life he could stop it, and habitually did so, or acquiesced in its being done for him; while G.o.d could not commit suicide or even cease for a single instant His continuous action. If man had the singular fancy of making himself absurd,--a taste confined to himself but attested by evidence exceedingly strong,--he could be as absurd as he liked; but G.o.d could not be absurd. Saint Thomas did not allow the Deity the right to contradict Himself, which is one of man's chief pleasures. While man enjoyed what was, for his purposes, an unlimited freedom to be wicked,--a privilege which, as both Church and State bitterly complained and still complain, he has outrageously abused,--G.o.d was Goodness, and could be nothing else.

While man moved about his relatively s.p.a.cious prison with a certain degree of ease, G.o.d, being everywhere, could not move. In one respect, at least, man's freedom seemed to be not relative but absolute, for his thought was an energy paying no regard to s.p.a.ce or time or order or object or sense; but G.o.d's thought was His act and will at once; speaking correctly, G.o.d could not think; He is. Saint Thomas would not, or could not, admit that G.o.d was Necessity, as Abelard seems to have held, but he refused to tolerate the idea of a divine maniac, free from moral obligation to himself. The atmosphere of Saint Louis surrounds the G.o.d of Saint Thomas, and its pure ether shuts out the corruption and pollution to come,--the Valois and Bourbons, the Occams and Hobbes's, the Tudors and the Medicis, of an enlightened Europe.

The theology turns always into art at the last, and ends in aspiration. The spire justifies the church. In Saint Thomas's Church, man's free will was the aspiration to G.o.d, and he treated it as the architects of Chartres and Laon had treated their famous fleches. The square foundation-tower, the expression of G.o.d's power in act,--His Creation,--rose to the level of the Church facade as a part of the normal unity of G.o.d's energy; and then, suddenly, without show of effort, without break, without logical violence, became a many-sided, voluntary, vanishing human soul, and neither Villard de Honnecourt nor Duns Scotus could distinguish where G.o.d's power ends and man's free will begins. All they saw was the soul vanishing into the skies. How it was done, one does not care to ask; in a result so exquisite, one has not the heart to find fault with "adresse."

About Saint Thomas's theology we need not greatly disturb ourselves; it can matter now not much, whether he put more pantheism than the law allowed or more materialism than Duns Scotus approved--or less of either--into his universe, since the Church is still on the spot, responsible for its own doctrines; but his architecture is another matter. So scientific and structural a method was never an accident or the property of a single mind even with Aristotle to prompt it.

Neither his Church nor the architect's church was a sketch, but a completely studied structure. Every relation of parts, every disturbance of equilibrium, every detail of construction was treated with infinite labour, as the result of two hundred years of experiment and discussion among thousands of men whose minds and whose instincts were acute, and who discussed little else. Science and art were one. Thomas Aquinas would probably have built a better cathedral at Beauvais than the actual architect who planned it; but it is quite likely that the architect might have saved Thomas some of his errors, as pointed out by the Councils of 1276. Both were great artists; perhaps in their professions, the greatest that ever lived; and both must have been great students beyond their practice.

Both were subject to constant criticism from men and bodies of men whose minds were as acute and whose learning was as great as their own. If the Archbishop of Canterbury and the Bishop of Paris condemned Thomas, the Bernardines had, for near two hundred years, condemned Beauvais in advance. Both the "Summa Theologiae" and Beauvais Cathedral were excessively modern, scientific, and technical, marking the extreme points reached by Europe on the lines of scholastic science. This is all we need to know. If we like, we can go on to study, inch by inch, the slow decline of the art. The essence of it--the despotic central idea--was that of organic unity both in the thought and the building. From that time, the universe has steadily become more complex and less reducible to a central control. With as much obstinacy as though it were human, it has insisted on expanding its parts; with as much elusiveness as though it were feminine, it has evaded the attempt to impose on it a single will. Modern science, like modern art, tends, in practice, to drop the dogma of organic unity. Some of the mediaeval habit of mind survives, but even that is said to be yielding before the daily evidence of increasing and extending complexity. The fault, then, was not in man, if he no longer looked at science or art as an organic whole or as the expression of unity. Unity turned itself into complexity, multiplicity, variety, and even contradiction. All experience, human and divine, a.s.sured man in the thirteenth century that the lines of the universe converged. How was he to know that these lines ran in every conceivable and inconceivable direction, and that at least half of them seemed to diverge from any imaginable centre of unity! Dimly conscious that his Trinity required in logic a fourth dimension, how was the schoolman to supply it, when even the mathematician of to-day can only infer its necessity? Naturally man tended to lose his sense of scale and relation. A straight line, or a combination of straight lines, may have still a sort of artistic unity, but what can be done in art with a series of negative symbols? Even if the negative were continuous, the artist might express at least a negation; but supposing that Omar's kinetic a.n.a.logy of the ball and the players turned out to be a scientific formula!--supposing that the highest scientific authority, in order to obtain any unity at all, had to resort to the Middle Ages for an imaginary demon to sort his atoms!--how could art deal with such problems, and what wonder that art lost unity with philosophy and science! Art had to be confused in order to express confusion; but perhaps it was truest, so.

Some future summer, when you are older, and when I have left, like Omar, only the empty gla.s.s of my scholasticism for you to turn down, you can amuse yourselves by going on with the story after the death of Saint Louis, Saint Thomas, and William of Lorris, and after the failure of Beauvais. The pathetic interest of the drama deepens with every new expression, but at least you can learn from it that your parents in the nineteenth century were not to blame for losing the sense of unity in art. As early as the fourteenth century, signs of unsteadiness appeared, and, before the eighteenth century, unity became only a reminiscence. The old habit of centralizing a strain at one point, and then dividing and subdividing it, and distributing it on visible lines of support to a visible foundation, disappeared in architecture soon after 1500, but lingered in theology two centuries longer, and even, in very old-fashioned communities, far down to our own time; but its values were forgotten, and it survived chiefly as a stock jest against the clergy. The pa.s.sage between the two epochs is as beautiful as the Slave of Michael Angelo; but, to feel its beauty, you should see it from above, as it came from its radiant source. Truth, indeed, may not exist; science avers it to be only a relation; but what men took for truth stares one everywhere in the eye and begs for sympathy. The architects of the twelfth and thirteenth centuries took the Church and the universe for truths, and tried to express them in a structure which should be final.

Knowing by an enormous experience precisely where the strains were to come, they enlarged their scale to the utmost point of material endurance, lightening the load and distributing the burden until the gutters and gargoyles that seem mere ornament, and the grotesques that seem rude absurdities, all do work either for the arch or for the eye; and every inch of material, up and down, from crypt to vault, from man to G.o.d, from the universe to the atom, had its task, giving support where support was needed, or weight where concentration was felt, but always with the condition of showing conspicuously to the eye the great lines which led to unity and the curves which controlled divergence; so that, from the cross on the fleche and the keystone of the vault, down through the ribbed nervures, the columns, the windows, to the foundation of the flying b.u.t.tresses far beyond the walls, one idea controlled every line; and this is true of Saint Thomas's Church as it is of Amiens Cathedral.

The method was the same for both, and the result was an art marked by singular unity, which endured and served its purpose until man changed his att.i.tude toward the universe. The trouble was not in the art or the method or the structure, but in the universe itself which presented different aspects as man moved. Granted a Church, Saint Thomas's Church was the most expressive that man has made, and the great Gothic cathedrals were its most complete expression.

Perhaps the best proof of it is their apparent instability. Of all the elaborate symbolism which has been suggested for the Gothic cathedral, the most vital and most perfect may be that the slender nervure, the springing motion of the broken arch, the leap downwards of the flying b.u.t.tress,--the visible effort to throw off a visible strain,--never let us forget that Faith alone supports it, and that, if Faith fails, Heaven is lost. The equilibrium is visibly delicate beyond the line of safety; danger lurks in every stone. The peril of the heavy tower, of the restless vault, of the vagrant b.u.t.tress; the uncertainty of logic, the inequalities of the syllogism, the irregularities of the mental mirror,--all these haunting nightmares of the Church are expressed as strongly by the Gothic cathedral as though it had been the cry of human suffering, and as no emotion had ever been expressed before or is likely to find expression again.

The delight of its aspirations is flung up to the sky. The pathos of its self-distrust and anguish of doubt is buried in the earth as its last secret. You can read out of it whatever else pleases your youth and confidence; to me, this is all.

THE END
