Part 18

"As the real motions, both of the earth and the planets, are unequable, it was requisite to have some mode of representing their inequalities; and accordingly the ancient theory of excentrics and epicycles was retained so far as was requisite for this purpose." In the case of Mercury's orbit he makes suppositions which are extremely complex, although they manifest his apprehension of the difficulties attendant on the common theory of his own time; but he verified many of his views by astronomical observations; and his approximations to modern science, and the light he threw on preceding discoveries, establish the fame of Nicholas Copernicus.

On a review of the life of Copernicus, and the conclusions he reached, the mental and moral qualities of the man come out with conspicuous and extraordinary lustre.

He was a mathematician, thus walking in the footsteps of Roger Bacon. This science, since the days of Euclid, had been pursued with untiring ardor, and many who neglected to study, or who, by their own imagination, distorted the actual phenomena of nature, addicted themselves to the investigation of the abstract properties of magnitude and number. Copernicus, in his knowledge of mathematical principles, and in his skilful application of them to astronomical inquiries, probably surpassed all his contemporaries. And, at the same time, he had that inventive genius which is fruitful in suggestions, such as become pioneers in the path of scientific demonstration. His independence of mind, his real originality, and his boldness in the pursuit of truth are quite as remarkable as the qualities just noticed; indeed, they are involved in or they led to the latter of these. "I beg you," says one of his admiring disciples, "to have this opinion concerning that learned man, my preceptor, that he was an ardent admirer and follower of Ptolemy; but when he was compelled by phenomena and demonstration, he thought he did well to aim at the same mark at which Ptolemy had aimed, though with a bow and shaft very different from his." We must recollect that Ptolemy says 'He who is to follow philosophy must be a freeman in mind.' Copernicus knew very well that there were many prepared to challenge his conclusions, and perhaps to bring theological objections to the principles of science which he had been constrained to adopt. "If, perchance," it is said in the preface to his book on astronomy, "there be vain babblers who, knowing nothing of mathematics, yet assume the right of judging, on account of some place of Scripture, perversely wrested to their purpose, and who blame and attack my undertaking, I heed them not, and look upon their judgments as rash and contemptible."

Copernicus had a profound reverence for Scripture. He regarded it as the Word of God, able to make us wise unto salvation; and none of his discoveries pertaining to the laws of nature shook for one moment his confidence in the revelation of the gospel. Copernicus delayed for years the publication of his discoveries to the world. That delay had been thought to have proceeded from something like fear, or, at least, caution, lest views in some respects so novel should rouse ecclesiastical antagonism and expose him to serious persecution. But the words used in the dedication of his astronomical work seem to point in another direction. It is there said that he had kept it four times the nine years recommended by Horace, and published it at last in compliance with the entreaties of his friend, Cardinal Schomberg. "Though I know," it is added, "that the thoughts of a philosopher do not depend on the judgment of the many, his study being to seek out truth in all things as far as that is permitted by God to human reason, yet when I considered how absurd that doctrine would appear, I long hesitated whether I should publish my book, or whether it were not better to follow the example of the Pythagoreans and others, who delivered their doctrines only by tradition and to friends." From this passage we should infer that he apprehended controversy rather than persecution, that for the former he had no desire, that he was without ambition, and felt no wish to found a new school, but would rather leave truths he had learned quietly to make their way through the world.

The fame of Copernicus is now wide as the world. He painted a portrait of himself which fell into the hands of Tycho Brahe; and he wrote an epigram upon the subject, to the effect that the whole earth could not contain the whole of the man who whirled it along the ocean of ether. Less extravagant was the grateful enthusiasm of Rhiticus, a disciple of Copernicus, when he wrote, "God has given to my excellent preceptor a reign without end, which may He vouchsafe to guide, govern, and increase, to the restoration of astronomical truth. Amen!"

"The Copernican system" is the name now generally given to the almost universal scientific belief that the earth and the planets revolve around the sun, though the system carried out and perfected by Kepler, Newton, Halley, Laplace, and others is by no means perfectly identical with the theory of the German astronomer. But the inextricable interweaving of his name with opinions sanctioned by the entire scientific world, is one of the noblest conceivable tributes to the magnitude and lustre of his renown.

His death was in harmony with his life. Shortly before he expired he repeated these words:

"Non parem Paulo gratiam requiro, Veniam Petri neque posco; sed quam In crucis ligno dederat latroni Sedulus oro."

He had lived a life of Christian virtue--imitating his master, who went about doing good, healing the sick and preaching the gospel to the poor--yet, so far from having anything whereof to boast before God, he said himself that he felt his need of infinite mercy, and in seeking the pardon of his sins he would not place himself on a level with Paul or Peter, but rather choose a point of self-humiliation by the side of the penitent thief.

His work on the revolution of the celestial bodies was passing through the press at the time of his fatal illness in 1543, when he had completed his seventieth year and was brought to him just before he breathed his last; and thus, as has been beautifully expressed, he was "made to touch the first printed copy of his book when the sense of touch was gone, seeing it only as a dim object through the deepening dusk."

He is buried under a flat stone in one of the side aisles of his own cathedral at Frauenburg. On his monument is painted a half-length portrait, pale, thin, aged, but with an expression of countenance intelligent and pleasant. His hair and eyes are black; he is habited as a priest; his hands are joined in prayer; before him is a crucifix, at his feet a skull, and behind him are a globe and a pair of compasses. His devotion, his deadness to the world, and his love of science are thus aptly symbolized.

MARTIN LUTHER

(1483-1546)

[Illustration: Luther and a group of men. [TN]]

Martin Luther, the greatest of the Protestant Reformers of the sixteenth century, was born at Eisleben on November 10, 1483. His father was a miner in humble circumstances; his mother, as Melancthon records, was a woman of exemplary virtue, and particularly esteemed in her walk of life. Shortly after Martin's birth his parents removed to Mansfeld, where their circumstances ere long improved by industry and perseverance. Their son was sent to school; and both at home and in school his training was severe. His father sometimes whipped him, he says, "for a mere trifle till the blood came," and he was subjected to the scholastic rod fifteen times in one day! Luther's schooling was completed at Magdeburg and Eisenach, and at the latter place he attracted by his singing the notice of a good lady of the name of Cotta, who welcomed the lad into her family and provided him with a comfortable home during his stay there. Here under Trebonius he made good progress in Latin. In 1501, when he had reached his eighteenth year, he entered the university of Erfurt, with the view of qualifying himself for the legal profession. He went through the usual studies in the classics and the schoolmen, and took his degree of doctor of philosophy, or master of arts, in 1505, when he was twenty-one years of age.

Previous to this, however, a profound change of feeling had begun in him. The death of a friend, and the terror of a thunder-storm, deeply impressed him. Chancing one day to examine the Vulgate in the university library, he saw with astonishment that there were more gospels and epistles than in the lectionaries. He was arrested by the contents of his newly found treasure. His heart was deeply touched, and he resolved to devote himself to a spiritual life. He separated himself from his friends and fellow-students, and withdrew into the Augustinian convent at Erfurt. Here he spent the next three years of his life--years of peculiar interest and significance; for it was during this time that he laid, in the study of the Bible and of Augustine, and with the assistance of his life-long friend Staupitz, the foundation of those doctrinal convictions which were afterward to rouse and strengthen him in his life-long struggle. He describes very vividly the spiritual crisis through which he passed, the burden of sin which so long lay upon him, "too heavy to be borne," and the relief that he at length found in the clear apprehension of the doctrine of the "forgiveness of sins," through the grace of Christ.

In the year 1507 Luther was ordained a priest, and in the following year he removed to Wittenberg, destined to derive its chief celebrity from his name. He became a teacher in the new university founded there by the Elector Frederick of Saxony. At first he lectured on dialectics and physics, but his heart was already given to theology, and in 1509 he became a bachelor of theology, and commenced lecturing on the Holy Scriptures. His lectures made a great impression, and the novelty of his views already began to excite attention. "This monk," said the rector of the university, "will puzzle our doctors and bring in a new doctrine." Besides lecturing, he began to preach, and his sermons reached a wider audience, and produced a still more powerful influence. They were printed and widely circulated in Germany, France, and England, so that his doctrines were diffused throughout Europe. His words, as Melancthon says, were "born not on his lips, but in his soul," and they moved profoundly the souls of all who heard them. In 1511 he was sent on a mission to Rome, and he has described very vividly what he saw and heard there. His devout and unquestioning reverence--for he was yet in his own subsequent view "a most insane papist"--appears in strange conflict with his awakened thoughtfulness and the moral indignation at the abuses of the papacy beginning to stir him.

[Illustration: Luther introduced to the home of Frau Cotta.]

On Luther's return from Rome he was made a doctor of the Holy Scriptures, and his career as a reformer may be said to have commenced. The system of indulgences had reached a scandalous height. The idea that it was in the power of the Church to forgive sin had gradually grown into the notion that the Pope could issue pardons of his own free will, which, being dispensed to the faithful, exonerated them from the consequences of their transgressions. The sale of these pardons had become an organized part of the papal system. Money was largely needed at Rome, and its numerous emissaries sought everywhere to raise funds by the sale of "indulgences;" the principal of these was John Tetzel, a Dominican friar, who had established himself at Jueterberg (1517). Luther's indignation at the shameless traffic which this man carried on, finally became irrepressible. "God willing," he exclaimed, "I will beat a hole in his drum." He drew out ninety-five theses on the doctrine of indulgences, which on October 31st he nailed up on the door of the church at Wittenberg, and which he offered to maintain in the university against all impugners. The general purport of these theses was to deny to the Pope all right to forgive sins. This sudden and bold step of Luther was all that was necessary to awaken a wide-spread excitement. Tetzel was forced to retreat from the borders of Saxony to Frankfort-on-the-Oder, where he drew out and published a set of counter-theses and publicly committed those of Luther to the flames. The students at Wittenberg retaliated by burning Tetzel's theses. The elector refused to interfere, and the excitement increased as new combatants--Hochstratten, Prierias, and Eck--entered the field. Eck was an able man, and an old friend of Luther's, and the argument between him and the reformer was especially vehement. In 1518 the latter was joined by Melancthon, who became one of his dearest and most trusted friends.

At first the Pope, Leo X., took little heed of the disturbance; he is reported even to have said, when he heard of it, that "Friar Martin was a man of genius, and that he did not wish to have him molested." Some of the cardinals, however, saw the real character of the movement, which gradually assumed a seriousness evident even to the Pope; and Luther received a summons to appear at Rome, and answer for his theses (1518). Once again in Rome, it is unlikely he would ever have been allowed to return. His university and the elector interfered, and a legate was sent to Germany to hear and determine the case. Cardinal Cajetan was the legate, and he was but little fitted to deal with Luther. He would enter into no argument with him, but merely called upon him to retract. Luther refused, and fled from Augsburg, whither he had gone to meet the papal representative. The task of negotiation was then undertaken by Miltitz, a German, who was envoy of the Pope to the Saxon court, and by his greater address, a temporary peace was obtained. This did not last long. The reformer was too deeply moved to keep silent. "God hurries and drives me," he said; "I am not master of myself; I wish to be quiet, and am hurried into the midst of tumults." Dr. Eck and he held a memorable disputation at Leipsic (1519), in which the subject of argument was no longer merely the question of indulgences, but the general power of the Pope. The disputation, of course, came to no practical result; each controversialist claimed the victory, and Luther in the meantime made progress in freedom of opinion, and attacked the papal system as a whole more boldly. Erasmus and Hutten joined in the conflict, which waxed more loud and threatening.

In 1520 the reformer published his famous address to the "Christian Nobles of Germany." This was followed in the same year by a treatise "On the Babylonish Captivity of the Church." In these works, both of which circulated widely and powerfully influenced many minds, Luther took firmer and broader ground; he attacked not only the abuses of the papacy and its pretensions to supremacy, but also the doctrinal system of the Church of Rome. "These works," Ranke says, "contain the kernel of the whole Reformation." The papal bull containing forty-one theses was issued against him; the dread document, with other papal books, was burned before an assembled multitude of doctors, students, and citizens, at the Elster Gate of Wittenberg. Germany was convulsed with excitement. Eck (who had been the chief agent in obtaining the bull) fled from place to place, glad to escape with his life, and Luther was everywhere the hero of the hour.

Charles V. had at this time succeeded to the empire, and he convened his first diet of the sovereigns and states at Worms. The diet met in the beginning of 1521; an order was issued for the destruction of Luther's books, and he himself was summoned to appear before the diet. This was above all what he desired--to confess the truth before the assembled powers of Germany. He resolved--having received a safe-conduct--to obey the summons, come what would. All Germany was moved by his heroism; his journey resembled a triumph; the threats of enemies and the anxieties of friends alike failed to move him. "I am resolved to enter Worms," he said, "although as many devils should set at me as there are tiles on the housetops." His appearance and demeanor before the diet, and the firmness with which he held his ground and refused to retract, all make a striking picture. He was not allowed to defend his opinions. "Unless I be convinced," he said, "by Scripture and reason, I neither can nor dare retract anything, for my conscience is a captive to God's word, and it is neither safe nor right to go against conscience. There I take my stand. I can do no otherwise. So help me God. Amen."

On his return from Worms he was seized, at the instigation of his friend, the Elector of Saxony, and safely lodged in the old castle of the Wartburg. The affair was made to assume an aspect of violence, but in reality it was designed to secure him from the destruction which his conduct at Worms would certainly have provoked, he having been placed under the ban of the empire. He remained in this shelter for about a year, concealed in the guise of a knight. His chief employment was his translation of the Scriptures into his native language. He composed various treatises besides, and injured his health by sedentary habits and hard study. His imagination became morbidly excited, and he thought he saw and heard the Evil One mocking him while engaged in his literary tasks; the blot from the inkstand that he hurled at him is still shown on the wall of his chamber. The subject of the personality and presence of Satan was a familiar one with Luther, and he has many things about it in his Table-talk.

[Illustration: Martin Luther before the Council of Worms.]

The disorders which sprang up in the progress of the Reformation recalled Luther to Wittenberg. He felt that his presence was necessary to restrain Carlstadt and others, and, defying any danger to which he might still be exposed, he returned in 1522 to the old scene of his labors, rebuked the unruly spirits who had acquired power in his absence, and resumed with renewed energy his interrupted work. He strove to arrest the excesses of the Zwickau fanatics, and counselled peace and order to the inflamed peasants; while he warned the princes and nobles of the unchristian cruelty of many of their doings, which had driven the people to exasperation and frenzy. At no period of his life is he greater than now, in the stand which he made against lawlessness on the one hand and tyranny on the other. He vindicated his claim to be a reformer in the highest sense by the wise and manly part which he acted in this great social crisis in the history of Germany. In this year also he published his acrimonious reply to Henry VIII. on the seven sacraments. Although he had been at first united in a common cause with Erasmus, estrangement had gradually sprung up between the scholar of Rotterdam and the enthusiastic reformer of Wittenberg. This estrangement came to an open breach in the year 1525, when Erasmus published his treatise "De Libero Arbitrio." Luther immediately followed with his counter-treatise "De Servo Arbitrio." The controversy raged loudly between them; and in the vehemence of his hostility to the doctrine of Erasmus, Luther was led into various assertions of a very questionable kind, besides indulging in the wild abuse of his opponent's character. The quarrel was an unhappy one on both sides; and it must be confessed there is especially a want of generosity in the manner in which Luther continued to cherish the dislike which sprang out of it.

In the course of the same year Luther married Katharina von Bora, one of nine nuns who, under the influence of his teaching, had emancipated themselves from their religious vows. The step rejoiced his enemies and even alarmed some of his friends, like Melancthon. But it greatly contributed to his happiness, while it served to enrich and strengthen his character. All the most interesting and touching glimpses we get of him henceforth are in connection with his wife and children.

Two years after his marriage he fell into a dangerous sickness and depression of spirits, from which he was only aroused by the dangers besetting Christendom from the advance of the Turks. Two years later, in 1529, he engaged in his famous conference at Marburg with Zwingli and other Swiss divines. The following year finds him at Coburg, while the diet sat at Augsburg. It was deemed prudent to intrust the interests of the Protestant cause to Melancthon, who attended the diet, but Luther removed to Coburg to be at hand for consultation. The drawing up of the Augsburg Confession marks the culmination of the German Reformation (1530); and the life of Luther from henceforth possesses comparatively little interest. He survived sixteen years longer, but they are years marked by few incidents of importance. He died at Eisleben on February 18, 1546, and was buried at Wittenberg.

Luther's character presents an imposing combination of great qualities. Endowed with broad human sympathies, massive energy, manly and affectionate simplicity, and rich, if sometimes coarse humor, he is at the same time a spiritual genius. His intuitions of divine truth were bold, vivid, and penetrating, if not comprehensive; and he possessed the art which God alone gives to the finer and abler spirits that He calls to do special work in this world, of kindling other souls with the fire of his own convictions, and awakening them to a higher consciousness of religion and duty. He was a leader of men, therefore, and a Reformer in the highest sense. His powers were fitted to his appointed task; it was a task of Titanic magnitude, and he was a Titan in intellectual robustness and moral strength and courage. It was only the divine energy which swayed him, and of which he recognized himself the organ, that could have accomplished what he did.

View him as a mere theologian, and there are others who take higher rank. There is a lack of patient thoughtfulness and philosophical temper in his doctrinal discussions; but the absence of these very qualities gave vigor to his bold, if sometimes crude, conceptions, and enabled him to triumph in the struggle for life and death in which he was engaged. To initiate the religious movement which was destined to renew the face of Europe, required a gigantic will, which, instead of being crushed by opposition, or frightened by hatred, should only gather strength from the fierceness of the conflict before it. To clear the air thoroughly, as he himself said, thunder and lightning are necessary. Upon the whole, it may be said that history presents few greater characters--few that excite at once more love and admiration, and in which we see tenderness, humor, and a certain picturesque grace and poetic sensibility more happily combined with a lofty and magnanimous, if sometimes rugged, sublimity.

Luther's works are very voluminous, partly in Latin, and partly in German. Among those of more general interest are his Table-Talk, his letters, and sermons. His Commentaries on Galatians and the Psalms are still read; and he was one of the great leaders of sacred song, his hymns, rugged but intense and expressive, having an enduring power.
