When he was about eleven years old Bruno was sent to Naples to be taught logic, dialectics and humanities. When fifteen he entered the Dominican Monastery in Naples, and assumed the clerical habit of that order. Here he gave up his baptismal name of Filippo and assumed that of Giordano, according to the monastic custom. In 1572 he was ordained priest.
His reasons for thus entering the Church are scarcely far to seek. Of intellectual bent, and studious rather than martial in his habits and inclinations, there was but one career open to him. To be sure the Dominican Order was the most narrow and most bigoted of all, as the current punning expression "Domini canes" will indicate. Still it was at that time the most powerful, especially in the kingdom of Naples, which was then ruled by Spain. The old cloister had been once the home of St. Thomas Aquinas, whose works Bruno claimed at his trial he had always by him, "continually reading, studying and restudying them, and holding them dear."
This was the age when efforts to put down every heresy had been redoubled. The fanaticism of Loyola, and the decision of the Council of Trent "to erase with fire and sword the slightest traces of heresy," made a poor frame work in which to place the picture of a liberal minded scholar. Bruno soon learned this at his cost. Even during his novitiate he was accused of giving away images of the saints, and of giving bad advice to his associates. In 1576 he was accused of apologizing for the heresy of Arius, that the Son was begotten of the Father, and so not consubstantial nor coeternal with Him, but created by Him and subordinate to Him; (which was condemned by the Council of Nice, 325, and contradicted in the Nicene Creed;) admiring its scholastic form, rather than its abstract truth. Disgusted with his treatment he left Naples and went to Rome. Even here he was molested in the Cloister of Minerva (note the pagan name), and was met with an accusation of 130 specifications. He then abandoned his garb and his cloister and escaped from Rome, beginning thus the nomadic life which he continued until immured in the dungeons of the Inquisition at Venice, sixteen years later. Through these wanderings one must follow him, if one would become familiar with his life and traits.
He now resumed for a time his baptismal name, and traveled to a town on the Gulf of Genoa, where he taught youth and young gentlemen. Then he passed on to Turin and Venice, where he spent weeks in futile attempts to find work. But the schools and the printing houses were closed because of the plague. In Venice however he managed to print his first book on "The Signs of the Times;" or rather this was his first book to appear in print. It seems that before he left Naples he wrote "The Ark of Noah," a satirical allegory. In this he represented that the animals held a formal meeting in the Ark, to settle questions of precedence and rank, and that the presiding officer, the Ass, was in danger of losing his position and his influence, because his power lay rather in hoofs than horns. Throughout most of his life Bruno constantly scored and criticised Asinity; it was frequently the topic of his invective, and those who read between his lines were probably quite justified in regarding these frequent allusions as references to the ignorance, bigotry and credulity of the Monks.
From Venice Bruno went to Padua, where some of the Dominican friars persuaded him to resume monastic costume, since it made travel easier and safer. Thence by way of Brescia and Milan he may be followed to Bergamo. At Milan he first heard of his future friend Sir Philip Sydney. From Bergamo he resolved to go to Lyons, but learning that he would find anything but welcome there he turned aside and crossed the Alps, arriving in Geneva in the Spring of 1579. Here he was visited by a distinguished Neapolitan exile, the Marquis De Vico, who persuaded him again to lay aside his clerical garb, and who gave him the dress of a gentleman, including a sword.
Here is raised the great question,--Did Bruno adopt Calvinism? Before the Inquisition fifteen years later he practically denied this, yet acknowledged attending the lectures of Balbani, of Lucca, as well as of others who taught and preached in Geneva. Under the regulations of the Academy (University), where he had already registered, certain regulations must be complied with, and Bruno appears to have obeyed them in at least a certain degree. But the immediate cause for his departure from Geneva appears to have been one of his outbreaks of cynicism and accurate scholarship, since in 1579 he was called before the Council for having caused to be printed a document enumerating twenty errors made by the Professor of Philosophy (de la Faye) in one of his lectures. The latter was incensed and outraged at this criticism and disparagement of his views and learning, and the quarrel assumed unexpected magnitude, since Bruno, on his second appearance before the Consistory or supreme tribunal of the Church, denied the charges and called the ministers "pedagogues." These gentlemen decided to refuse him communion unless he should confess and repent of his faults and make due apology. His acceptance of these conditions not being hearty enough to suit his judges, he was admonished and excluded from the communion. These steps lead to greater contrition on his part, and the ban of excommunication was withdrawn. This sentence of exclusion was the only one within the power of the Consistory to pass, but does not prove that Bruno had accepted the protestant faith, nor partaken of its communion. In fact at his trial he steadfastly denied this. It seemed however, to disgust him with Calvinism, against which thereafter he never ceased to inveigh. Later he contrasted it with Lutheranism which was far more tolerant, and still later gave him a heartier welcome. Calvin, it must be remembered, had written a polemic against Servetus, "in which it is shown to be lawful to coerce heretics by the sword." As between the council of Trent and Calvin it certainly must have been hard, in those days, to select either a faith, or an abiding place where that faith might be peaceably practised. Doubtless Bruno's views concerning the philosophy of Aristotle conflicted with those of the church authorities, for Beza (Calvin's follower), had stated that they did not propose to swerve one particle from the opinions of that Greek philosopher, to whom, though of pagan origin, the Church, both Roman and Protestant, was for centuries so firmly bound.
And so shaking the dust of Geneva from his feet he journeyed to Lyons, where he failed utterly to find occupation, and then on to Toulouse, where he remained about two years. Here he took a Doctorate in Theology in order to compete for a vacant chair. To this he was elected by the students, as the custom then was in most of the scholia or universities. For two sessions he lectured on Aristotle. Had this University required of him that he should attend mass, as did some others, he could not have done so, owing to his excommunication; though just why exclusion from a Calvinistic academy should debar him from Catholic mass does not appear. Toulouse was a warm place for heretics; the burning of 14,000 of them at its capture will prove this. A few years (35) after he left it Vanini was burned for heretic notions. It is hardly to be believed that Bruno could pass two years or more here without controversies arising from his teaching. But his nominal reason for leaving, in 1581, and going to Paris, was the war then raging in Southern France, under Henry of Navarre.
Before leaving Toulouse he completed his "Clavis Magna" or "Great Key," the last word--as he seemed to think--on the art of memory. Only one volume of this great work, which, in his peculiarly egotistical way, he said is "superlatively pregnant," was ever published, and that in England, the "Sigillus Sigillorum." It must not be forgotten that it was on both teaching and practising this art of memory that Bruno, throughout his career, prided himself. He was even not averse, at least at certain periods of his career, to the belief that he had some secret system for this purpose, or even received occult aid. But when summoned before Henry III, to whose ears had come his fame, and asked whether the memory he had and the art he professed were natural or due to magic, he proved that a good memory was a cultivated natural product. He then dedicated to the King a book on "The Art of Memory."
But this was shortly after his arrival in Paris, in 1581, where he quickly became famous. A course of thirty lectures on "The Thirty Divine Attributes" of St. Thomas Aquinas would have given him a chair, could he have attended mass.
His residence in Paris was marked by an extraordinary literary activity. He published in succession De Umbris Idearum (Shadow of Ideas), dedicated to Henry III, (this included the Art of Memory just mentioned) Cantus Circaeus (Incantation of Circe) dedicated to Prince Henry; De Compendiosa Architectura et Complemento Artis Lulli (Compendious Architecture); Il Candelaio (The Torchbearer); these all appeared in 1582. These varied greatly in character. The first was devoted to the metaphysics of the art of remembering, with an analysis of that faculty, and these second was given up to the same general topic. It was all obscure, hence perhaps its popularity. Brunnhofer says that it was "a convenient means of introducing Bruno to strange universities, gaining him favor with the great, or helping him out of pressing need of money. It was his exoteric philosophy with which he could carefully drape the philosophy of a religion hostile to the Church, and ride as a hobby horse in his unfruitful humors." Nevertheless we must believe in his sincerity. The "Compendious Architecture" is the first of his works in which Bruno deals with the views of Raymond Lully, a "logical calculus and mnemonic scheme in one" (McIntyre) that had many imitators. For Lully Bruno seems to have the greatest regard, this appearing in many ways. Lully, by the way, was a Spanish scholastic and alchemist, who was born on one of the Balearic Islands in 1235. He went as a missionary to the Mahommedans, and spent much time in Asia and Africa. He figures largely in the history of the alchemists and as a practitioner of the occult.
The "Torchbearer" was a work of very different character. It was described as a "Comedy" by one who described himself as "Academico di nulla academia, ditto il fastidito: In tristitia hilaris, hilaritate tristis." It is essentially a satire on the predominant vices of pedantry, superstition and selfishness or sordid love. Though lacking in dramatic power it is regarded as second to nothing of its kind and time. Its dramatis personae are personified types, not individuals. It was realistic even in its vulgarity, for obscenity was prevalent in the literature of those days. But in it Bruno struck at what seemed to him his greatest enemy, i. e. pedantry.
There were at this time in Paris two great Universities, one the College de France, with liberal tendencies, and opposed to the Jesuits and all pedantry; the other the Sorbonne, for centuries the guardian of the Catholic faith, endowed with the right of censorship, which must have been exercised over Bruno's works. In which of these, though surely in one of them, Bruno was made an Extraordinary Lecturer history has failed to record. He must have offended both, since he was anxious to be taken back into the Church, yet was revolutionary in his teaching. More than thirty years later Nostitz, one of his pupils, paid tribute to his versatility and skill, saying "he was able to discourse impromptu on any suggested subject, to speak extensively and elaborately without preparation, so that he attracted many pupils and admirers in Paris." (McIntyre). But Bruno belonged to the literally peripatetic school, and in 1583 he forsook Paris for London, because as he says of "tumults," leaving it to the imagination whether these were civil or scholastic.
Elizabeth reigned at this time; her influence made England a harbor of safety for religious and other mental suspects. She had a penchant for Italians and their language; two of her physicians were Italians, and Florio was ever welcome at her court. To this court Bruno also was welcomed, and, basking for sometime in the sunshine of her regard and patronage, passed there the happiest portion of his unhappy life. Oxford was at that time the stronghold of Aristotelianism. One of its statutes ordained that "Bachelors and Masters who did not follow Aristotle faithfully were liable to a fine of five shillings for every point of divergence, and for every fault committed against the Logic of the Organon." (McIntyre). In Oxford at this time, unfortunately, theology was the only live issue; of science as of real scholarship there was little or none. (Its predominant trait of those days is still, perhaps, its dominant feature to-day). To this university Bruno addressed a letter, couched in vainglorious and egotistical terms, craving permission to lecture there. This was not received with favor, while his doctrines met with small encouragement at this ancient seat of learning, which Bruno later stigmatized as the "widow of true science." But opportunity was afforded him to dispute publicly before a noble visitor in June, 1583, a Polish prince; one Alasco, for whom great public entertainment had been provided. His opponent, defeated by fifteen unanswerable syllogisms, resorted to scurrility and abuse. This public exhibition put an end to the lectures on the Immortality of the Soul which Bruno had been allowed to give, and he returned to London.
Shortly after this he published his Cena (Ash Wednesday Supper) in which he ridiculed the Oxford doctors, saying among other things that they were much better acquainted with beer than with Greek. But he criticised too cynically and lost thereby in popularity. This led to the appearance of the Causa, a dialogue, in which he was less vindictive. He admitted in this that there was much in the old institution which was admirable; that it was even the first in Europe, that speculative philosophy first flourished there, and that thence, "the splendor of one of the noblest and rarest spheres of philosophy, in our times almost extinct, was diffused to all other academies in civilized lands." What he most condemned was the too great attention given to language and words while the realistics for which words stand were neglected. Doctors were easily made and doctorates too cheaply bought. His charge in brief was that they mistook the shadow for the substance; a charge even yet too commonly justified among the strongholds of theology and other speculative dogmas.
Returning to London after this experience Bruno went to live with Mauvissiere, the French Ambassador. While the English records make no mention of his presence it is yet quite certain that he was frequently at Court, and that men like Sydney, Greville, Temple and others were his frequent associates. But as the Ambassador's influence was on the wane, he was not equal to his great trust. At this time our philosopher spoke of himself as one "whom the foolish hate, the ignoble despise, whom the wise love, the learned admire," etc. (McIntyre). Of Queen Elizabeth he wrote in most fulsome phrases, such as she too dearly loved. Before his judges, a few years later, Bruno apologized for his exaggerated expressions concerning a Protestant ruler, claiming that when he spoke of her as "divine" he meant it not as a term of worship, but as an epithet like those which the ancients bestowed upon their rulers; claiming further that he knew he erred in thus praising a heretic.
Bruno published seven works in England. The first was "Explicatio triginta Sigillorum," the Thirty Seals thus explained being hints for acquiring, arranging and remembering all arts and sciences. To it was added his Sigillus Sigillorum for comparing and explaining all mental operations. Then came an Italian dialogue "La Cena de le Ceneri" or Ash Wednesday Supper. This was written in praise and extension of the Copernican theory, indeed quite exceeding it in teaching the identity of matter, the infinity of the universe, the possibility of life on other spheres, with a painstaking attempt to show that these notions do not conflict with those of Mother Church. Next came "De Causa, Principio et Uno." (Cause, Principle and Unity). This treated of the immanence of spirit, the eternity of matter, the potential divinity of life, the origin of sin and death, and many other similar abstruse topics. It was followed by De l'Infinito Universo ed Mondi, with numerous reasons for believing the universe to be infinite and full of innumerable worlds, with the divine essence everywhere pervading.
All these works appeared in 1583. In 1584 appeared his "Spacio de la Bestia Triofante" or Expulsion of the Triumphant Beast. In this prose poem Jupiter, repenting his errors, resolves to expel the many beasts that occupy his heavenly sphere--the constellations--and to substitute for them the virtues. In the council of the gods convened by him many subjects are discussed, among them the history of religions, the contrasts between natural and revealed religions and the fundamental forms of morality. In this allegory Jupiter represents of course the human spirit; the Bear, the Scorpion, etc., are the vices to be expelled. Unfortunately the book was quite generally regarded as attack upon the Church or the Pope, though what he really struck at was the credulity of mankind. It was dedicated to Sir Philip Sydney. Then came his "Cabala del Cavallo Pegasio" or Cabal, dedicated to a suppositious Bishop who was made to impersonate the spirit of ignorance and sloth. It is a mordant satire on Asinity, including credulity and unquestioning faith. After this he dedicated another work to Sidney. "Degl' Heroici Furori" (Enthusiasms of the Noble), a collection of sonnets with prose commentaries, like Dante's Vita Nuova, touching on the love for spiritual beauty arising from that for physical beauty attaining a climax in a sort of ecstasy by union with the divine. These sonnets possess a very high literary value aside from their other interest.
When his ambassadorial patron was recalled Bruno probably returned to Paris with him, during the latter part of 1585. Here he spent a year amidst constant turmoil and excitement, and at his own expense. Though he attempted reconciliation with the Church he was regarded as an apostate. He held one more public disputation in which he advanced one hundred and twenty theses against the teaching of the Sorbonne, his side being taken by its rival, the College de France. The outcome cannot have been brilliantly favorable, since he soon after left Paris, in June, 1586. The collection of charges above alluded to was published in Paris after Bruno's departure, and again in Wittenberg, under the title "Excubitor" (The Ambassador). It was an arraignment of the Aristotelians, based on the words of that great master himself. Bruno claimed the same right to criticise Aristotle that the latter claimed to criticise his predecessors. In it Bruno says, "It is a poor mind that will think with the multitude because it is a multitude; truth is not altered by the opinions of the vulgar or the confirmation of the many;"--and again--"it is more blessed to be wise in truth in face of opinion than to be wise in opinion in face of truth." (McIntyre, p. 50).
In addition to this Bruno had also published, before leaving Paris, a commentary on the Physics of Aristotle.
Tarrying somewhat by the wayside Bruno reached Wittenberg, where, in 1586, he matriculated at its University, Marburg having curtly rejected him. Describing him here McIntyre styles him the "Knight Errant of Philosophy." Here Lutheranism dominated the theological faculty, while the philosophical faculty was dominated by Calvinism; views concerning the person of Christ, the "Real Presence," and the doctrine of Predestination keeping them apart in spite of Melancthon's attempt to reunite the two factions. From the Lutheran party Bruno obtained permission to lecture, and so for two years he taught from the Organon of Aristotle, as well as the writings of Raymond Lulli. To the University senate he dedicated a work on Lulli, "De Lampade Combinatoria Lulliana," whose chief purpose was to teach one how to find "an indefinite number of propositions and middle terms for speaking and arguing." He regarded it as the only key to the Lullian writings, as well as a clue to a great many of the mysteries of the Pythagoreans and Cabalists. It was soon followed by "De Progressu et Lampade Venatoria Logicorum," intended to enable one to "dispute promptly and copiously on any subject."
But again fate compelled a change of residence, for the Calvanistic and Ducal party gained in political ascendancy, to which party Bruno, as a Copernican, would have appeared as a heretic. After delivering an eloquent address of farewell he moved on, his next abiding place being Prague, where Rudolph II, of Bohemia, was posing as the friend of all learned men. Here he already had friends at court, and here he introduced himself with another Lullian work. To the Emperor he next dedicated a work of iconoclastic type, "One hundred and sixty articles against the mathematicians and philosophers of the day." For this the Emperor granted him the sum of three hundred dollars, and in January, 1589, he shifted again to Helmstadt, in Brunswick, where he matriculated again in the then youngest of the German Universities. This had been founded only twelve years before by Duke Julius, who was extremely liberal in his views, and intended to found a model institution, in which theology should not play too dominant a part. But while he received here a certain recognition fate again sported with him, for the Duke died four months after his arrival. Bruno obtained permission to pronounce a funeral oration, desiring to express his gratitude to the memory of one who had opened such an institution, so free to all lovers of the Muses and to exiles like himself, who were here protected from the greedy maw of the Roman wolf, whereas in Italy he had been chained to a superstitious cult. It was full of allusions to the papal tyranny which was infecting the world with the rankest poison of ignorance and vice.
The fatuous simplicity and the worldly blindness which Bruno displayed, in ever setting foot inside of Italian or papal territory after the delivery of this Oratio Consolatoria, may in one way be appreciated but never understood or explained. Moreover he had made himself persona non grata as well to the Protestants, who were scarcely more liberal than the Catholics. It appears that the great Boethius, superintendent of the Church at Helmstadt, had acted both as judge and executioner, and publicly excommunicated Bruno without a hearing, since there is extant a letter appealing from his arbitrary judgment and malice. The grounds for this judgment were never made clear, since no attention was ever paid to the appeal; but inasmuch as Bruno never really joined the Protestant profession it must have been meant to inflict some species of social ostracism. Boethius had himself to be suppressed later. But Bruno, finding too many enemies, left for Frankfort in 1590, "in order to get two books printed."
These were his two great Latin Works, "De Minimo" and "De Immenso," the introduction to the latter being the "De Monade." He worked at these with his own hands. In the introduction to the former his publisher stated that before its final revision Bruno had been hurriedly called away by an unforseen chance. This sudden departure may have been due to a refusal of the town Council to permit his residence there, or it may have been a call to Zürich, where he spent a few months with one Hainzel, who had a leaning toward the Black Arts. Bruno wrote for him "De Imaginum Compositione," a manual of his Art of Memory. In this Swiss city he also dictated a work "Summa Terminorum Metaphysicorum," which was not published until 1609, and then in Marburg. But Bruno returned to Frankfort in 1591, where he obtained permission to publish his De Minimo. This work was on the "three fold minimum and measurement, being the elements of three speculative and several practical sciences." This like the two next mentioned was a Latin poem, after the fashion of Lucretius. The De Monade, Numero et Figura dealt with the Monad, and with the elements of a more esoteric science, while in the De Immenso et Innumerabilibus, the Immeasurable and Innumerable, he dealt with the Universe and the worlds. These three poems contain Bruno's complete philosophy of God and Nature.
While thus staying in Frankfort for the second time Bruno was invited by a young Venetian patrician to pay him a visit, and become his tutor in those arts in which the philosopher excelled. It was the most unfortunate event in Bruno's unhappy life when he accepted this apparently tempting invitation. Mocenigo, his host, was of good family, but shallow, vain, weak-minded and dishonest, with the fashionable taste of his day for the black arts. It is quite possible that he was moreover the tool of the Inquisition, which had long desired to entrap Bruno. It is probable moreover that the latter quite failed to appreciate how unenviably he was regarded by that Church to which he still felt that he belonged. Furthermore Venice was then a Republic and free, and he longed for his beloved Italy again.
En route to Venice he spent three months in Padua, teaching there and gathering around himself pupils, even in that short time. He had barely left it when Galileo was invited there to teach; as Riehl has said, "the creator of modern science following in the steps of its prophet."
Early in 1592 Bruno went to live in Mocenigo's house. Trouble soon began. Entirely apart in temperament and characteristics, they soon disagreed. The pupil was deeply disappointed at not acquiring that mastery over the secrets of nature for which he had hoped, and found that there was no quick way to acquire a retentive and replete memory. And so Mocenigo announced to his friend Ciotto, the bookseller, his intent to gain from Bruno all he could and then denounce him to the Holy Office. While others were thus conspiring against him Bruno was writing a work on "The Seven Liberal Arts" and on "Seven Other Inventive Arts," intending to present it to the Pope, hoping thus to obtain absolution and be released from the ban of excommunication.
When Bruno at last appreciated the dangers by which he was surrounded he announced his intent to go again to Frankfort to have some of his books printed, and so took his leave of Mocenigo. On the following day, in May, 1592, Bruno was seized by six men, using force, who locked him in an upper story of Mocenigo's house. The next day he was transferred to an underground cellar, and the following night to the prison of the Inquisition. May 23rd his former host denounced him, with a cunning and lying statement concerning some of his views and teachings. Thus he was reported as stating that Christ's miracles were only apparent, that He and the apostles were magicians, that the Catholic faith was full of blasphemies against God, that the Friars befouled the world and should not be allowed to preach, that they were asses, and the doctrines of the Church were asses' beliefs, etc. (McIntyre). This was followed two days later by a second denunciation in which Mocenigo went to a diabolical extreme of deceit and hypocrisy; stating that all the time he was entertaining Bruno he was promising himself to bring him before the Holy Office. Within forty-eight hours the Holy Tribunal met to consider the matter; before them appeared the book-sellers who had known Bruno in Zürich and Frankfort, and before them came Bruno in his own behalf, professing his entire willingness to tell the whole truth. Within a few days Mocenigo made yet another deposition, denouncing Bruno's statements about the infallible Church. On the following day Bruno was again heard in his own defense, and appealed to the famous and fallacious doctrine of two-fold truth, acknowledging that he had taught too much as a philosopher rather than as an honest man and Christian, and that he had based his teachings too much on sense and reason and not enough on faith;--so specious had become his argument with the terrors of the Inquisition before him. He further claimed that his intent had been not to impugn the faith but to exalt philosophy. He then beautifully epitomized his own views, claiming that he believed in an infinite universe, in an infinite divine potency, holding it unworthy of an infinite power to create a finite world, when he could produce so vast an infinity; with Pythagoras he regarded this world as one of many stars,--innumerable worlds. This universe he held to be governed by a universal providence, existent in two forms;--one nature, the shadow or footprint of deity, the other the ineffable essence of God, always inexplicable. Concerning the triune Godhead he confessed certain philosophic doubts as well as concerning the use of the term "persons" in these distinctions, while he quoted St. Augustine to the same effect. The miracles he had always believed to be divine and genuine; concerning the Holy Mass and the Transubstantiation he agreed with the Church. As the days went by he became the more insistent upon his orthodoxy. He condemned the heretic writings of Melancthon, Luther and Calvin, expressed respect for the writings of Lulli because of their philosophical bearings, while for St. Thomas Aquinas he had the most profound regard.
Other counts in the indictment which he had to face were his doubts concerning the miracles, the sacraments and the incarnation, his praise of heretics and heretic princes and his familiarity with the magic arts. He finally made a formal solemn abjuration of all the errors he had ever committed, and the heresies he had ever uttered, or doubts expressed or believed, praying only that the Holy Office would receive him back into the Church where he might rest in peace. Further examinations were held and the earlier processes against him in Naples and Rome recalled. After this there was a period of apparent quiet save that he remained in prison. It is not known to what tortures he may have been subjected, but it is recorded that he knelt before his judges asking their pardon, and God's, for all his faults, and professed himself ready for any penance, apparently not yet realizing the fate in store for him.
