CHAPTER XVI

SAINT THOMAS AQUINAS

Long before Saint Francis's death, in 1226, the French mystics had exhausted their energies and the siecle had taken new heart. Society could not remain forever balancing between thought and act. A few gifted natures could absorb themselves in the absolute, but the rest lived for the day, and needed shelter and safety. So the Church bent again to its task, and bade the Spaniard Dominic arm new levies with the best weapons of science, and flaunt the name of Aristotle on the Church banners along with that of Saint Augustine. The year 1215, which happened to be the date of Magna Charta and other easily fixed events, like the birth of Saint Louis, may serve to mark the triumph of the schools. The pointed arch revelled at Rheims and the Gothic architects reached perfection at Amiens just as Francis died at Assisi and Thomas was born at Aquino. The Franciscan Order itself was swept with the stream that Francis tried to dam, and the great Franciscan schoolman, Alexander Hales, in 1222, four years before the death of Francis, joined the order and began lecturing as though Francis himself had lived only to teach scholastic philosophy.

The rival Dominican champion, Albertus Magnus, began his career a little later, in 1228. Born of the noble Swabian family of Bollstadt, in 1193, he drifted, like other schoolmen, to Paris, and the Rue Maitre Albert, opposite Notre Dame, still records his fame as a teacher there. Thence he passed to a school established by the order at Cologne, where he was lecturing with great authority in 1243 when the general superior of the order brought up from Italy a young man of the highest promise to be trained as his assistant.

Thomas, the new pupil, was born under the shadow of Monte Cassino in 1226 or 1227. His father, the Count of Aquino, claimed descent from the imperial line of Swabia; his mother, from the Norman princes of Sicily; so that in him the two most energetic strains in Europe met. His social rank was royal, and the order set the highest value on it. He took the vows in 1243, and went north at once to help Albertus at Cologne. In 1245, the order sent Albertus back to Paris, and Thomas with him. There he remained till 1248 when he was ordered to Cologne as assistant lecturer, and only four years afterwards, at twenty-five years old, he was made full professor at Paris. His industry and activity never rested till his death in 1274, not yet fifty years old, when he bequeathed to the Church a mass of manuscript that tourists will never know enough to estimate except by weight. His complete works, repeatedly printed, fill between twenty and thirty quarto volumes. For so famous a doctor, this is almost meagre. Unfortunately his greatest work, the "Summa Theologiae," is unfinished--like Beauvais Cathedral.

Perhaps Thomas's success was partly due to his memory which is said to have been phenomenal; for, in an age when cyclopaedias were unknown, a cyclopaedic memory must have counted for half the battle in these scholastic disputes where authority could be met only by authority; but in this case, memory was supported by mind. Outwardly Thomas was heavy and slow in manner, if it is true that his companions called him "the big dumb ox of Sicily"; and in fashionable or court circles he did not enjoy reputation for acute sense of humour. Saint Louis's household offers a picture not wholly clerical, least of all among the King's brothers and sons; and perhaps the dinner-table was not much more used then than now to abrupt interjections of theology into the talk about hunting and hounds; but however it happened, Thomas one day surprised the company by solemnly announcing--"I have a decisive argument against the Manicheans!" No wit or humour could be more to the point-- between two saints that were to be--than a decisive argument against enemies of Christ, and one greatly regrets that the rest of the conversation was not reported, unless, indeed, it is somewhere in the twenty-eight quarto volumes; but it probably lacked humour for courtiers.

The twenty-eight quarto volumes must be closed books for us. None but Dominicans have a right to interpret them. No Franciscan--or even Jesuit--understands Saint Thomas exactly or explains him with authority. For summer tourists to handle these intricate problems in a theological spirit would be altogether absurd; but, for us, these great theologians were also architects who undertook to build a Church Intellectual, corresponding bit by bit to the Church Administrative, both expressing--and expressed by--the Church Architectural. Alexander Hales, Albert the Great, Thomas Aquinas, Duns Scotus, and the rest, were artists; and if Saint Thomas happens to stand at their head as type, it is not because we choose him or understand him better than his rivals, but because his order chose him rather than his master Albert, to impose as authority on the Church; and because Pope John XXII canonized him on the ground that his decisions were miracles; and because the Council of Trent placed his "Summa" among the sacred books on their table; and because Innocent VI said that his doctrine alone was sure; and finally, because Leo XIII very lately made a point of declaring that, on the wings of Saint Thomas's genius, human reason has reached the most sublime height it can probably ever attain.

Although the Franciscans, and, later, the Jesuits, have not always shown as much admiration as the Dominicans for the genius of Saint Thomas, and the mystics have never shown any admiration whatever for the philosophy of the schools, the authority of Leo XIII is final, at least on one point and the only one that concerns us. Saint Thomas is still alive and overshadows as many schools as he ever did; at all events, as many as the Church maintains. He has outlived Descartes and Leibnitz and a dozen other schools of philosophy more or less serious in their day. He has mostly outlived Hume, Voltaire, and the militant sceptics. His method is typical and classic; his sentences, when interpreted by the Church, seem, even to an untrained mind, intelligible and consistent; his Church Intellectual remains practically unchanged, and, like the Cathedral of Beauvais, erect, although the storms of six or seven centuries have prostrated, over and over again, every other social or political or juristic shelter. Compared with it, all modern systems are complex and chaotic, crowded with self-contradictions, anomalies, impracticable functions and outworn inheritances; but beyond all their practical shortcomings is their fragmentary character. An economic civilization troubles itself about the universe much as a hive of honey-bees troubles about the ocean, only as a region to be avoided. The hive of Saint Thomas sheltered God and man, mind and matter, the universe and the atom, the one and the multiple, within the walls of an harmonious home.

Theologians, like architects, were supposed to receive their Church complete in all its lines; they were modern judges who interpreted the laws but never invented it. Saint Thomas merely selected between disputed opinions, but he allowed himself to wander very far afield, indeed, in search of opinions to dispute. The field embraced all that existed, or might have existed, or could never exist. The immense structure rested on Aristotle and Saint Augustine at the last, but as a work of art it stood alone, like Rheims or Amiens Cathedral, as though it had no antecedents. Then, although, like Rheims, its style was never meant to suit modern housekeeping and is ill-seen by the Ecole des Beaux Arts, it reveals itself in its great mass and intelligence as a work of extraordinary genius; a system as admirably proportioned as any cathedral and as complete; a success not universal either in art or science.

Saint Thomas's architecture, like any other work of art, is best studied by itself as though he created it outright; otherwise a tourist would never get beyond its threshold. Beginning with the foundation which is God and God's active presence in His Church, Thomas next built God into the walls and towers of His Church, in the Trinity and its creation of mind and matter in time and space; then finally he filled the Church by uniting mind and matter in man, or man's soul, giving to humanity a free will that rose, like the fleche, to heaven. The foundation--the structure--the congregation-- are enough for students of art; his ideas of law, ethics, and politics; his vocabulary, his syllogisms, his arrangement are, like the drawings of Villard de Honnecourt's sketch-book, curious but not vital. After the eleventh-century Romanesque Church of Saint Michael came the twelfth-century Transition Church of the Virgin, and all merged and ended at last in the thirteenth-century Gothic Cathedral of the Trinity. One wants to see the end.

The foundation of the Christian Church should be--as the simple deist might suppose--always the same, but Saint Thomas knew better. His foundation was Norman, not French; it spoke the practical architect who knew the mathematics of his art, and who saw that the foundation laid by Saint Bernard, Saint Victor, Saint Francis, the whole mystical, semi-mystical, Cartesian, Spinozan foundation, past or future, could not bear the weight of the structure to be put on it. Thomas began by sweeping the ground clear of them. God must be a concrete thing, not a human thought. God must be proved by the senses like any other concrete thing; "nihil est in intellectu quin prius fuerit in sensu"; even if Aristotle had not affirmed the law, Thomas would have discovered it. He admitted at once that God could not be taken for granted.

The admission, as every boy-student of the Latin Quarter knew, was exceedingly bold and dangerous. The greatest logicians commonly shrank from proving unity by multiplicity. Thomas was one of the greatest logicians that ever lived; the question had always been at the bottom of theology; he deliberately challenged what every one knew to be an extreme peril. If his foundation failed, his Church fell. Many critics have thought that he saw dangers four hundred years ahead. The time came, about 1650-1700, when Descartes, deserting Saint Thomas, started afresh with the idea of God as a concept, and at once found himself charged with a deity that contained the universe; nor did the Cartesians--until Spinoza made it clear--seem able or willing to see that the Church could not accept this deity because the Church required a God who caused the universe. The two deities destroyed each other. One was passive; the other active. Thomas warned Descartes of a logical quicksand which must necessarily swallow up any Church, and which Spinoza explored to the bottom. Thomas said truly that every true cause must be proved as a cause, not merely as a sequence; otherwise they must end in a universal energy or substance without causality--a source.

Whatever God might be to others, to His Church he could not be a sequence or a source. That point had been admitted by William of Champeaux, and made the division between Christians and infidels. On the other hand, if God must be proved as a true cause in order to warrant the Church or the State in requiring men to worship Him as Creator, the student became the more curious--if a churchman, the more anxious--to be assured that Thomas succeeded in his proof, especially since he did not satisfy Descartes and still less Pascal. That the mystics should be dissatisfied was natural enough, since they were committed to the contrary view, but that Descartes should desert was a serious blow which threw the French Church into consternation from which it never quite recovered.

"I see motion," said Thomas: "I infer a motor!" This reasoning, which may be fifty thousand years old, is as strong as ever it was; stronger than some more modern inferences of science; but the average mechanic stated it differently. "I see motion," he admitted: "I infer energy. I see motion everywhere; I infer energy everywhere." Saint Thomas barred this door to materialism by adding: "I see motion; I cannot infer an infinite series of motors: I can only infer, somewhere at the end of the series, an intelligent, fixed motor." The average modern mechanic might not dissent but would certainly hesitate. "No doubt!" he might say; "we can conduct our works as well on that as on any other theory, or as we could on no theory at all; but, if you offer it as proof, we can only say that we have not yet reduced all motion to one source or all energies to one law, much less to one act of creation, although we have tried our best." The result of some centuries of experiment tended to raise rather than silence doubt, although, even in his own day, Thomas would have been scandalized beyond the resources of his Latin had Saint Bonaventure met him at Saint Louis's dinner-table and complimented him, in the King's hearing, on having proved, beyond all Franciscan cavils, that the Church Intellectual had necessarily but one first cause and creator--himself.

The Church Intellectual, like the Church Architectural, implied not one architect, but myriads, and not one fixed, intelligent architect at the end of the series, but a vanishing vista without a beginning at any definite moment; and if Thomas pressed his argument, the twentieth-century mechanic who should attend his conferences at the Sorbonne would be apt to say so. "What is the use of trying to argue me into it? Your inference may be sound logic, but is not proof. Actually we know less about it than you did. All we know is the thing we handle, and we cannot handle your fixed, intelligent prime motor. To your old ideas of form we have added what we call force, and we are rather further than ever from reducing the complex to unity. In fact, if you are aiming to convince me, I will tell you flatly that I know only the multiple, and have no use for unity at all."

In the thirteenth century men did not depend so much as now on actual experiment, but the nominalist said in effect the same thing. Unity to him was a pure concept, and any one who thought it real would believe that a triangle was alive and could walk on its legs. Without proving unity, philosophers saw no way to prove God. They could only fall back on an attempt to prove that the concept of unity proved itself, and this phantasm drove the Cartesians to drop Thomas's argument and assert that "the mere fact of having within us the idea of a thing more perfect than ourselves, proves the real existence of that thing." Four hundred years earlier Saint Thomas had replied in advance that Descartes wanted to prove altogether too much, and Spinoza showed mathematically that Saint Thomas had been in the right. The finest religious mind of the time--Pascal-- admitted it and gave up the struggle, like the mystics of Saint- Victor.

Thus some of the greatest priests and professors of the Church, including Duns Scotus himself, seemed not wholly satisfied that Thomas's proof was complete, but most of them admitted that it was the safest among possible foundations, and that it showed, as architecture, the Norman temper of courage and caution. The Norman was ready to run great risks, but he would rather grasp too little than too much; he narrowed the spacing of his piers rather than spread them too wide for safe vaulting. Between Norman blood and Breton blood was a singular gap, as Renan and every other Breton has delighted to point out. Both Abelard and Descartes were Breton. The Breton seized more than he could hold; the Norman took less than he would have liked.

God, then, is proved. What the schools called form, what science calls energy, and what the intermediate period called the evidence of design, made the foundation of Saint Thomas's cathedral. God is an intelligent, fixed prime motor--not a concept, or proved by concepts;--a concrete fact, proved by the senses of sight and touch. On that foundation Thomas built. The walls and vaults of his Church were more complex than the foundation; especially the towers were troublesome. Dogma, the vital purpose of the Church, required support. The most weighty dogma, the central tower of the Norman cathedral, was the Trinity, and between the Breton solution which was too heavy, and the French solution which was too light, the Norman Thomas found a way. Remembering how vehemently the French Church, under Saint Bernard, had protected the Trinity from all interference whatever, one turns anxiously to see what Thomas said about it; and unless one misunderstands him,--as is very likely, indeed, to be the case, since no one may even profess to understand the Trinity,--Thomas treated it as simply as he could. "God, being conscious of Himself, thinks Himself; his thought is Himself, his own reflection in the Verb--the so-called Son." "Est in Deo intelligente seipsum Verbum Dei quasi Deus intellectus." The idea was not new, and as ideas went it was hardly a mystery; but the next step was naif:--God, as a double consciousness, loves Himself, and realizes Himself in the Holy Ghost. The third side of the triangle is love or grace.

Many theologians have found fault with this treatment of the subject, which seemed open to every objection that had been made to Abelard, Gilbert de la Poree, or a thousand other logicians. They commonly asked why Thomas stopped the Deity's self-realizations at love, or inside the triangle, since these realizations were real, not symbolic, and the square was at least as real as any other combination of line. Thomas replied that knowledge and will--the Verb and the Holy Ghost--were alone essential. The reply did not suit every one, even among doctors, but since Saint Thomas rested on this simple assertion, it is no concern of ours to argue the theology. Only as art, one can afford to say that the form is more architectural than religious; it would surely have been suspicious to Saint Bernard. Mystery there was none, and logic little. The concept of the Holy Ghost was childlike; for a pupil of Aristotle it was inadmissible, since it led to nothing and helped no step toward the universe.

Admitting, if necessary, the criticism, Thomas need not admit the blame, if blame there were. Every theologian was obliged to stop the pursuit of logic by force, before it dragged him into paganism and pantheism. Theology begins with the universal,--God,--who must be a reality, not a symbol; but it is forced to limit the process of God's realizations somewhere, or the priest soon becomes a worshipper of God in sticks and stones. Theologists had commonly chosen, from time immemorial, to stop at the Trinity; within the triangle they were wholly realist; but they could not admit that God went on to realize Himself in the square and circle, or that the third member of the Trinity contained multiplicity, because the Trinity was a restless weight on the Church piers, which, like the central tower, constantly tended to fall, and needed to be lightened. Thomas gave it the lightest form possible, and there fixed it.

Then came his great tour-de-force, the vaulting of his broad nave; and, if ignorance is allowed an opinion, even a lost soul may admire the grand simplicity of Thomas's scheme. He swept away the horizontal lines altogether, leaving them barely as a part of decoration. The whole weight of his arches fell, as in the latest Gothic, where the eye sees nothing to break the sheer spring of the nervures, from the rosette on the keystone a hundred feet above down to the church floor. In Thomas's creation nothing intervened between God and his world; secondary causes become ornaments; only two forces, God and man, stood in the Church.

The chapter of Creation is so serious, and Thomas's creation, like every other, is open to so much debate, that no student can allow another to explain it; and certainly no man whatever, either saint or sceptic, can ever yet have understood Creation aright unless divinely inspired; but whatever Thomas's theory was as he meant it, he seems to be understood as holding that every created individual-- animal, vegetable, or mineral--was a special, divine act. Whatever has form is created, and whatever is created takes form directly from the will of God, which is also his act. The intermediate universals--the second-ary causes--vanish as causes; they are, at most, sequences or relations; all merge in one universal act of will; instantaneous, infinite, eternal.

Saint Thomas saw God, much as Milton saw him, resplendent in


    That glorious form, that light unsufferable,
      And that far-beaming blaze of Majesty,
     Wherewith he wont, at Heaven's high council-table,
      To sit the midst of Trinal Unity;

except that, in Thomas's thought, the council-table was a work- table, because God did not take counsel; He was an act. The Trinity was an infinite possibility of will; nothing within but

    The baby image of the giant mass        Of things to come at large.

Neither time nor space, neither matter nor mind, not even force existed, nor could any intelligence conceive how, even though they should exist, they could be united in the lowest association. A crystal was as miraculous as Socrates. Only abstract force, or what the schoolmen called form, existed undeveloped from eternity, like the abstract line in mathematics.

Fifty or a hundred years before Saint Thomas settled the Church dogma, a monk of Citeaux or some other abbey, a certain Alain of Lille, had written a Latin poem, as abstruse an allegory as the best, which had the merit of painting the scene of man's creation as far as concerned the mechanical process much as Thomas seems to have seen it. M. Haureau has printed an extract (vol. I, p. 352). Alain conceded to the weakness of human thought, that God was working in time and space, or rather on His throne in heaven, when nature, proposing to create a new and improved man, sent Reason and Prudence up to ask Him for a soul to fit the new body. Having passed through various adventures and much scholastic instruction, the messenger Prudence arrived, after having dropped her dangerous friend Reason by the way. The request was respectfully presented to God, and favourably received. God promised the soul, and at once sent His servant Noys--Thought--to the storehouse of ideas, to choose it:--

Ipse Deus rem prosequitur, producit in actum
Quod pepigit. Vocat ergo Noym quae praepaert illi
Numinis exemplar, humanae mentis Idaeam,
Ad cujus formam formetur spiritus omni
Munere virtutum dives, qui, nube caducae
Carnis odumbratus veletur corporis umbra.
Tunc Noys ad regis praeceptum singula rerum

Vestigans exempla, novam perquirit Idaeam.
Inter tot species, speciem vix invenit illam
Quam petit; offertur tandem quaesita petenti
. Hanc formam Noys ipsa Deo praesentat ut ejus
Formet ad exemplar animam. Tunc ille sigillum
Sumit, ad ipsius formae vestigia formam
Dans animae, vultum qualem deposcit Idaea
Imprimit exemplo; totas usurpat imago
Exemplaris opes, loquiturque figura sigillum.

God Himself pursues the task, and sets in act
What He promised. So He calls Noys to seek
A copy of His will, Idea of the human mind,
To whose form the spirit should be shaped,
Rich in every virtue, which, veiled in garb
Of frail flesh, is to be hidden in a shade of body,
Then Noys, at the King's order, turning one by one

Each sample, seeks the new Idea.
Among so many images she hardly finds that
Which she seeks; at last the sought one appears.
This form Noys herself brings to God for Him
To form a soul to its pattern. He takes the seal,
And gives form to the soul after the model
Of the form itself, stamping on the sample
The figure such as the Idea requires. The seal
Covers the whole field, and the impression expresses the stamp.

The translation is probably full of mistakes; indeed, one is permitted to doubt whether Alain himself accurately understood the process; but in substance he meant that God contained a storehouse of ideas, and stamped each creation with one of these forms. The poets used a variety of figures to help out their logic, but that of the potter and his pot was one of the most common. Omar Khayyam was using it at the same time with Alain of Lille, but with a difference: for his pot seems to have been matter alone, and his soul was the wine it received from God; while Alain's soul seems to have been the form and not the contents of the pot.

The figure matters little. In any case God's act was the union of mind with matter by the same act or will which created both. No intermediate cause or condition intervened; no secondary influence had anything whatever to do with the result. Time had nothing to do with it. Every individual that has existed or shall exist was created by the same instantaneous act, for all time. "When the question regards the universal agent who produces beings and time, we cannot consider him as acting now and before, according to the succession of time." God emanated time, force, matter, mind, as He might emanate gravitation, not as a part of His substance but as an energy of His will, and maintains them in their activity by the same act, not by a new one. Every individual is a part of the direct act; not a secondary outcome. The soul has no father or mother. Of all errors one of the most serious is to suppose that the soul descends by generation. "Having life and action of its own, it subsists without the body; ... it must therefore be produced directly, and since it is not a material substance, it cannot be produced by way of generation; it must necessarily be created by God. Consequently to suppose that the intelligence [or intelligent soul] is the effect of generation is to suppose that it is not a pure and simple substance, but corruptible like the body. It is therefore heresy to say that this soul is transmitted by generation." What is true of the soul should be true of all other form, since no form is a material substance. The utmost possible relation between any two individuals is that God may have used the same stamp or mould for a series of creations, and especially for the less spiritual: "God is the first model for all things. One may also say that, among His creatures some serve as types or models for others because there are some which are made in the image of others"; but generation means sequence, not cause. The only true cause is God. Creation is His sole act, in which no second cause can share." Creation is more perfect and loftier than generation, because it aims at producing the whole substance of the being, though it starts from absolute nothing."

Thomas Aquinas, when he pleased, was singularly lucid, and on this point he was particularly positive. The architect insisted on the controlling idea of his structure. The Church was God, and its lines excluded interference. God and the Church embraced all the converging lines of the universe, and the universe showed none but lines that converged. Between God and man, nothing whatever intervened. The individual was a compound of form, or soul, and matter; but both were always created together, by the same act, out of nothing. "Simpliciter fatendum est animas simul cum corporibus creari et infundi." It must be distinctly understood that souls were not created before bodies, but that they were created at the same time as the bodies they animate. Nothing whatever preceded this union of two substances which did not exist: "Creatio est productio alicujus rei secundum suam totam substantiam, nullo praesupposito, quod sit vel increatum vel ab aliquo creatum." Language can go no further in exclusion of every possible preceding, secondary, or subsequent cause, "Productio universalis entis a Deo non est motus nec mutatio, sed est quaedam simplex emanatio." The whole universe is, so to speak, a simple emanation from God.

The famous junction, then, is made!--that celebrated fusion of the universal with the individual, of unity with multiplicity, of God and nature, which had broken the neck of every philosophy ever invented; which had ruined William of Champeaux and was to ruin Descartes; this evolution of the finite from the infinite was accomplished. The supreme triumph was as easily effected by Thomas Aquinas as it was to be again effected, four hundred years later, by Spinoza. He had merely to assert the fact: "It is so! it cannot be otherwise!" "For the thousandth and hundred-thousandth time;--what is the use of discussing this prime motor, this Spinozan substance, any longer? We know it is there!" that--as Professor Haeckel very justly repeats for the millionth time--is enough.

One point, however, remained undetermined. The Prime Motor and His action stood fixed, and no one wished to disturb Him; but this was not the point that had disturbed William of Champeaux. Abelard's question still remained to be answered. How did Socrates differ from Plato--Judas from John--Thomas Aquinas from Professor Haeckel? Were they, in fact, two, or one? What made an individual? What was God's centimetre measure? The abstract form or soul which existed as a possibility in God, from all time,--was it one or many? To the Church, this issue overshadowed all else, for, if humanity was one and not multiple, the Church, which dealt only with individuals, was lost. To the schools, also, the issue was vital, for, if the soul or form was already multiple from the first, unity was lost; the ultimate substance and prime motor itself became multiple; the whole issue was reopened.

To the consternation of the Church, and even of his own order, Thomas, following closely his masters, Albert and Aristotle, asserted that the soul was measured by matter. "Division occurs in substances in ratio of quantity, as Aristotle says in his 'Physics.' And so dimensional quantity is a principle of individuation." The soul is a fluid absorbed by matter in proportion to the absorptive power of the matter. The soul is an energy existing in matter proportionately to the dimensional quantity of the matter. The soul is a wine, greater or less in quantity according to the size of the cup. In our report of the great debate of 1110, between Champeaux and Abelard, we have seen William persistently tempting Abelard to fall into this admission that matter made the man;--that the universal equilateral triangle became an individual if it were shaped in metal, the matter giving it reality which mere form could not give; and Abelard evading the issue as though his life depended on it. In fact, had Abelard dared to follow Aristotle into what looked like an admission that Socrates and Plato were identical as form and differed only in weight, his life might have been the forfeit. How Saint Thomas escaped is a question closely connected with the same inquiry about Saint Francis of Assisi. A Church which embraced, with equal sympathy, and within a hundred years, the Virgin, Saint Bernard, William of Champeaux and the School of Saint- Victor, Peter the Venerable, Saint Francis of Assisi, Saint Dominic, Saint Thomas Aquinas, and Saint Bonaventure, was more liberal than any modern State can afford to be. Radical contradictions the State may perhaps tolerate, though hardly, but never embrace or profess. Such elasticity long ago vanished from human thought.

Yet only Dominicans believe that the Church adopted this law of individualization, or even assented to it. If M. Jourdain is right, Thomas was quickly obliged to give it another form:--that, though all souls belonged to the same species, they differed in their aptitudes for uniting with particular bodies. "This soul is commensurate with this body, and not with that other one." The idea is double; for either the souls individualized themselves, and Thomas abandoned his doctrine of their instantaneous creation, with the bodies, out of nothing; or God individualized them in the act of creation, and matter had nothing to do with it. The difficulty is no concern of ours, but the great scholars who took upon themselves to explain it made it worse, until at last one gathers only that Saint Thomas held one of three views: either the soul of humanity was individualized by God, or it individualized itself, or it was divided by ratio of quantity, that is, by matter. This amounts to saying that one knows nothing about it, which we knew before and may admit with calmness; but Thomas Aquinas was not so happily placed, between the Church and the schools. Humanity had a form common to itself, which made it what it was. By some means this form was associated with matter; in fact, matter was only known as associated with form. If, then, God, by an instantaneous act, created matter and gave it form according to the dimensions of the matter, innocent ignorance might infer that there was, in the act of God, one world- soul and one world-matter, which He united in different proportions to make men and things. Such a doctrine was fatal to the Church. No greater heresy could be charged against the worst Arab or Jew, and Thomas was so well aware of his danger that he recoiled from it with a vehemence not at all in keeping with his supposed phlegm. With feverish eagerness to get clear of such companions, he denied and denounced, in all companies, in season and out of season, the idea that intellect was one and the same for all men, differing only with the quantity of matter it accompanied. He challenged the adherent of such a doctrine to battle; "let him take the pen if he dares!" No one dared, seeing that even Jews enjoyed a share of common sense and had seen some of their friends burn at the stake not very long before for such opinions, not even openly maintained; while uneducated people, who are perhaps incapable of receiving intellect at all, but for whose instruction and salvation the great work of Saint Thomas and his scholars must chiefly exist, cannot do battle because they cannot understand Thomas's doctrine of matter and form which to them seems frank pantheism.

So it appeared to Duns Scotus also, if one may assert in the Doctor Subtilis any opinion without qualification. Duns began his career only about 1300, after Thomas's death, and stands, therefore, beyond our horizon; but he is still the pride of the Franciscan Order and stands second in authority to the great Dominican alone. In denying Thomas's doctrine that matter individualizes mind, Duns laid himself open to the worse charge of investing matter with a certain embryonic, independent, shadowy soul of its own. Scot's system, compared with that of Thomas, tended toward liberty. Scot held that the excess of power in Thomas's prime motor neutralized the power of his secondary causes, so that these appeared altogether superfluous. This is a point that ought to be left to the Church to decide, but there can be no harm in quoting, on the other hand, the authority of some of Scot's critics within the Church, who have thought that his doctrine tended to deify matter and to keep open the road to Spinoza. Narrow and dangerous was the border-line always between pantheism and materialism, and the chief interest of the schools was in finding fault with each other's paths.

The opinions in themselves need not disturb us, although the question is as open to dispute as ever it was and perhaps as much disputed; but the turn of Thomas's mind is worth study. A century or two later, his passion to be reasonable, scientific, architectural would have brought him within range of the Inquisition. Francis of Assisi was not more archaic and cave-dweller than Thomas of Aquino was modern and scientific. In his effort to be logical he forced his Deity to be as logical as himself, which hardly suited Omnipotence. He hewed the Church dogmas into shape as though they were rough stones. About no dogma could mankind feel interest more acute than about that of immortality, which seemed to be the single point vitally necessary for any Church to prove and define as clearly as light itself. Thomas trimmed down the soul to half its legitimate claims as an immortal being by insisting that God created it from nothing in the same act or will by which He created the body and united the two in time and space. The soul existed as form for the body, and had no previous existence. Logic seemed to require that when the body died and dissolved, after the union which had lasted, at most, only an instant or two of eternity, the soul, which fitted that body and no other, should dissolve with it. In that case the Church dissolved, too, since it had no reason for existence except the soul. Thomas met the difficulty by suggesting that the body's form might take permanence from the matter to which it gave form. That matter should individualize mind was itself a violent wrench of logic, but that it should also give permanence--the one quality it did not possess--to this individual mind seemed to many learned doctors a scandal. Perhaps Thomas meant to leave the responsibility on the Church, where it belonged as a matter not of logic but of revealed truth. At all events, this treatment of mind and matter brought him into trouble which few modern logicians would suspect.

The human soul having become a person by contact with matter, and having gained eternal personality by the momentary union, was finished, and remains to this day for practical purposes unchanged; but the angels and devils, a world of realities then more real than man, were never united with matter, and therefore could not be persons. Thomas admitted and insisted that the angels, being immaterial,--neither clothed in matter, nor stamped on it, nor mixed with it,--were universals; that is, each was a species in himself, a class, or perhaps what would be now called an energy, with no other individuality than he gave himself.

The idea seems to modern science reasonable enough. Science has to deal, for example, with scores of chemical energies which it knows little about except that they always seem to be constant to the same conditions; but every one knows that in the particular relation of mind to matter the battle is as furious as ever. The soul has always refused to live in peace with the body. The angels, too, were always in rebellion. They insisted on personality, and the devils even more obstinately than the angels. The dispute was--and is--far from trifling. Mind would rather ignore matter altogether. In the thirteenth century mind did, indeed, admit that matter was something,--which it quite refuses to admit in the twentieth,--but treated it as a nuisance to be abated. To the pure in spirit one argued in vain that spirit must compromise; that nature compromised; that God compromised; that man himself was nothing but a somewhat clumsy compromise. No argument served. Mind insisted on absolute despotism. Schoolmen as well as mystics would not believe that matter was what it seemed,--if, indeed, it existed;--unsubstantial, shifty, shadowy; changing with incredible swiftness into dust, gas, flame; vanishing in mysterious lines of force into space beyond hope of recovery; whirled about in eternity and infinity by that mind, form, energy, or thought which guides and rules and tyrannizes and is the universe. The Church wanted to be pure spirit; she regarded matter with antipathy as something foul, to be held at arms' length lest it should stain and corrupt the soul; the most she would willingly admit was that mind and matter might travel side by side, like a doubleheaded comet, on parallel lines that never met, with a preestablished harmony that existed only in the prime motor.

Thomas and his master Albert were almost alone in imposing on the Church the compromise so necessary for its equilibrium. The balance of matter against mind was the same necessity in the Church Intellectual as the balance of thrusts in the arch of the Gothic cathedral. Nowhere did Thomas show his architectural obstinacy quite so plainly as in thus taking matter under his protection. Nothing would induce him to compromise with the angels. He insisted on keeping man wholly apart, as a complex of energies in which matter shared equally with mind. The Church must rest firmly on both. The angels differed from other beings below them' precisely because they were immaterial and impersonal. Such rigid logic outraged the spiritual Church.

Perhaps Thomas's sudden death in 1274 alone saved him from the fate of Abelard, but it did not save his doctrine. Two years afterwards, in 1276, the French and English churches combined to condemn it. Etienne Tempier, Bishop of Paris, presided over the French Synod; Robert Kilwardeby, of the Dominican Order, Archbishop of Canterbury, presided over the Council at Oxford. The synods were composed of schoolmen as well as churchmen, and seem to have been the result of a serious struggle for power between the Dominican and Franciscan Orders. Apparently the Church compromised between them by condemning the errors of both. Some of these errors, springing from Alexander Hales and his Franciscan schools, were in effect the foundation of another Church. Some were expressly charged against Brother Thomas. "Contra fratrem Thomam" the councils forbade teaching that--"quia intelligentiae non habent materiam, Deus non potest plures ejusdem speciei facere; et quod materia non est in angelis"; further, the councils struck at the vital centre of Thomas's system--"quod Deus non potest individua multiplicare sub una specie sine materia"; and again in its broadest form,--"quod formae non accipiunt divisionem nisi secundam materiam." These condemnations made a great stir. Old Albertus Magnus, who was the real victim of attack, fought for himself and for Thomas. After a long and earnest effort, the Thomists rooted out opposition in the order, and carried their campaign to Rome. After fifty years of struggle, by use of every method known in Church politics, the Dominican Order, in 1323, caused John XXII to canonize Thomas and in effect affirm his doctrine.

The story shows how modern, how heterodox, how material, how altogether new and revolutionary the system of Saint Thomas seemed at first even in the schools; but that was the affair of the Church and a matter of pure theology. We study only his art. Step by step, stone by stone, we see him build his church-building like a stonemason, "with the care that the twelfth-century architects put into" their work, as Viollet-le-Duc saw some similar architect at Rouen, building the tower of Saint-Romain: "He has thrown over his work the grace and finesse, the study of detail, the sobriety in projections, the perfect harmony," which belongs to his school, and yet he was rigidly structural and Norman. The foundation showed it; the elevation, which is God, developed it; the vaulting, with its balance of thrusts in mind and matter, proved it; but he had still the hardest task in art, to model man.

The cathedral, then, is built, and God is built into it, but, thus far, God is there alone, filling it all, and maintains the equilibrium by balancing created matter separately against created mind. The proportions of the building are superb; nothing so lofty, so large in treatment, so true in scale, so eloquent of multiplicity in unity, has ever been conceived elsewhere; but it was the virtue or the fault of superb structures like Bourges and Amiens and the Church universal that they seemed to need man more than man needed them; they were made for crowds, for thousands and tens of thousands of human beings; for the whole human race, on its knees, hungry for pardon and love. Chartres needed no crowd, for it was meant as a palace of the Virgin, and the Virgin filled it wholly; but the Trinity made their church for no other purpose than to accommodate man, and made man for no other purpose than to fill their church; if man failed to fill it, the church and the Trinity seemed equally failures. Empty, Bourges and Beauvais are cold; hardly as religious as a wayside cross; and yet, even empty, they are perhaps more religious than when filled with cattle and machines. Saint Thomas needed to fill his Church with real men, and although he had created his own God for that special purpose, the task was, as every boy knew by heart, the most difficult that Omnipotence had dealt with.

God, as Descartes justly said, we know! but what is man? The schools answered: Man is a rational animal! So was apparently a dog, or a bee, or a beaver, none of which seemed to need churches. Modern science, with infinite effort, has discovered and announced that man is a bewildering complex of energies, which helps little to explain his relations with the ultimate substance or energy or prime motor whose existence both science and schoolmen admit; which science studies in laboratories and religion worships in churches. The man whom God created to fill his Church, must be an energy independent of God; otherwise God filled his own Church with his own energy. Thus far, the God of Saint Thomas was alone in His Church. The beings He had created out of nothing--Omar's pipkins of clay and shape--stood against the walls, waiting to receive the wine of life, a life of their own.

Of that life, energy, will, or wine,--whatever the poets or professors called it,--God was the only cause, as He was also the immediate cause, and support. Thomas was emphatic on that point. God 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, God'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." God 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 God was the sole and immediate cause and support of everything in His creation, God 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 asserted 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 God, after the single, unalterable act or will which created. The only possible free will was that of God before the act. Abelard with his rigid logic averred that God had no freedom; being Himself whatever is most perfect, He produced necessarily the most perfect possible world. Nothing seemed more logical, but if God 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 God-- 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 God'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 God 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 God'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 amissio boni; 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 God 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 assume 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 asserts law, it can only assert force. Rigid theology went much further. In God'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 God. He persistently brought God 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 God to his aid, as though he felt the moral obligation of the Creator to help His creation.

At best the vision of God, 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 damnation, 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 God 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 God 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 class; 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 illustrate 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 God, 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 God!

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 God 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 God 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 space 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. God 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 accumulated until it acquired power to leap the obstacle. As Saint Thomas expressed it, the Prime Motor, Who was nothing else than God, 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 God.

This exclusion of what men commonly called freedom was carried still further in the process of explaining dogma. Supposing the con- duction to be insufficient for a given purpose; a purpose which shall require perfect conduction? Under ordinary circumstances, 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 God to a mechanism and man to a passive conductor of force. He has left, they say, nothing but God 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 passivity 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 assertion or assumption of ultimate unity has characterized the Law of Energy as emphatically as it has characterized the definition of God 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 God 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 God 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 God watched over man's temporal welfare far more anxiously than the State has ever done, and assigned him space in the Church which he never can have in the galleries of Parliament or Congress; more than all this, Saint Thomas and his God 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 God, Whose freedom suffered, from Saint Thomas, under restraints that man never would have tolerated. Saint Thomas did not allow God 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 God 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 God 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,--God was Goodness, and could be nothing else. While man moved about his relatively spacious prison with a certain degree of ease, God, 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 space or time or order or object or sense; but God's thought was His act and will at once; speaking correctly, God could not think; He is. Saint Thomas would not, or could not, admit that God 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 God 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 God, and he treated it as the architects of Chartres and Laon had treated their famous fleches. The square foundation-tower, the expression of God's power in act,--His Creation,--rose to the level of the Church facade as a part of the normal unity of God'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 God'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, assured 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 analogy 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 glass 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 passage 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 God, 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 buttresses 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 attitude 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 buttress,--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 buttress; 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.
