 Four centuries ago today, on February
16, 1600, the Roman Catholic Church executed Giordano Bruno, Italian philosopher
and scientist, for the crime of heresy. He was taken from his cell in the
early hours of the morning to the Piazza dei Fiori in Rome and burnt alive
at the stake. To the last, the church authorities were fearful of the ideas
of a man who was known throughout Europe as a bold and brilliant thinker.
In a peculiar twist to the gruesome affair, the executioners were ordered
to tie his tongue so that he would be unable to address those gathered.
-
-
- Throughout his life Bruno championed the Copernican system
of astronomy which placed the Sun, not the Earth, at the centre of the
Solar System. He opposed the stultifying authority of the church and refused
to recant his philosophical beliefs throughout his eight years of imprisonment
by the Venetian and Roman Inquisitions. His life stands as a testimony
to the drive for knowledge and truth that marked the astonishing period
of history known as the Renaissance"from which so much in modern art,
thought and science derives.
-
-
- In 1992, after 12 years of deliberations, the Roman Catholic
Church grudgingly admitted that Galileo Galilei had been right in supporting
the theories of Copernicus. The Holy Inquisition had forced an aged Galileo
to recant his ideas under threat of torture in 1633. But no such admission
has been made in the case of Bruno. His writings are still on the Vatican's
list of forbidden texts.
-
-
- The church is currently considering a new batch of apologies.
A theological commission headed by Cardinal Joseph Ratzinger, the head
of the Congregation for the Doctrine of the Faith, the modern successor
of the Inquisition, has completed an inquiry entitled "The Church
and the Faults of the Past: Memory in the Service of Reconciliation,"
which proposes making an apology for "past errors". The results
have been handed to Pope John Paul II, who is due to make a statement on
March 12. The execution of Bruno is one of the church's crimes being considered
but it is unlikely that major concessions will be made in his case. A number
of hard-line Catholic figures have opposed the investigation from the outset,
saying that excessive penitence and self-questioning could undermine faith
in the church and its institutions.
-
-
- The current attitude of the Roman Catholic Church to
Bruno is defined by a two-page entry in the latest edition of the Catholic
Encyclopaedia. It describes Bruno's "intolerance" and berates
him declaring "his attitude of mind towards religious truth was that
of a rationalist. (1) The article describes in detail Bruno's theological
errors and his lengthy detention at the hands of the Inquisition but fails
to mention the best-known fact"that the church authorities burnt him
alive at the stake.
-
-
- Bruno has long been revered as a martyr to scientific
truth. In 1889 a monument to him was erected at the location of his execution.
Such was the feeling for Bruno that scientists and poets paid tribute to
him and a book was written detailing his life's work. In a dedication for
a meeting held at the Contemporary Club in Philadelphia in 1890, American
poet Walt Whitman wrote: "As America's mental courage (the thought
comes to me today) is so indebted, above all current lands and peoples,
to the noble army of old-world martyrs past, how incumbent on us that we
clear those martyrs' lives and names, and hold them up for reverent admiration
as well as beacons. And typical of this, and standing for it and all perhaps,
Giordano Bruno may well be put, today and to come, in our New World's thankfulest
heart and memory."(2)
-
-
- Karl Marx's co-thinker Fredrick Engels summed up the
period that produced figures such as Bruno who challenged the church and
laid the basis for modern science. In an introduction written in the 1870s
to his unfinished work, the Dialectics of Nature, Engels wrote: "It
was the greatest progressive revolution that mankind had so far experienced,
a time which called for giants and produced giants"giants in power
of thought, passion and character, in universality and learning. The men
who founded the modern rule of the bourgeoisie had anything but bourgeois
limitations. On the contrary, the adventurous character of the time inspired
them to a greater or lesser degree. There was hardly any man of importance
then living who had not travelled extensively, who did not speak four or
five languages, who did not shine in a number of fields...
-
-
- "At that time natural science also developed in
the midst of the general revolution and was itself thoroughly revolutionary;
it had indeed to win in struggle its right of existence. Side by side with
the great Italians from whom modern philosophy dates, it provided its martyrs
for the stake and the dungeons of the Inquisition. And it is characteristic
that Protestants outdid Catholics in persecuting the free investigation
of nature. Calvin had Servetus burnt at the stake when the latter was on
the point of discovering the circulation of the blood, and indeed he kept
him roasting alive during two hours; for the Inquisition at least it sufficed
to have Giordano Bruno simply burnt alive." (3)
-
-
- What is most characteristic of Bruno is his vigorous
appeal to reason and logic, rather than religious dogma, as the basis for
determining truth. In a manner that anticipates the Enlightenment thinkers
of the 18th century, he wrote in one of his final works, De triplici minimo
(1591): "He who desires to philosophise must first of all doubt all
things. He must not assume a position in a debate before he has listened
to the various opinions, and considered and compared the reasons for and
against. He must never judge or take up a position on the evidence of what
he has heard, on the opinion of the majority, the age, merits, or prestige
of the speaker concerned, but he must proceed according to the persuasion
of an organic doctrine which adheres to real things, and to a truth that
can be understood by the light of reason." (4)
-
-
- A complex intellectual figure
-
-
- An examination of Bruno's philosophical legacy reveals
a complex figure who was influenced by the various intellectual trends
of the time, in a period when modern science was just beginning to emerge.
His enthusiastic polemics earned the admiration of the most advanced thinkers
of the period and the loathing of the church, whose authority was being
shaken to the core by learned assaults such as these.
-
-
- Bruno was born in the town of Nola, near Naples, in 1548
at the dawn of the revolution in astronomy, which was heralded by the publication
of Copernicus' De revolutionibus orbium coelestium libri VI in 1543. Copernicus
demonstrated that the Sun, not the Earth, was the centre of a finite universe
with the planets on circular orbits around it and the stars on a fixed
sphere a considerable distance beyond.
-
-
- The Copernican system not only challenged the church's
cosmological views but the rigid social hierarchy of feudalism. The previous
neatly ordered view of the universe with the Earth at the centre reinforced
the rigid feudal order with serfs at the bottom and the Pope at the pinnacle.
The dangerous implication of the Copernican theory was that if the church's
credo of infallibility could be challenged in the cosmological arena then
its social position was also cast into doubt.
-
-
- The church was already under siege from all sides. In
1517 Martin Luther nailed his Ninety-Five Theses to the church door in
Germany denouncing the practices of the Roman Catholic Church, the first
blow in the Protestant Reformation that swept across Europe. The Vatican
responded with a counterattack"the Counter Reformation"on anyone
who appeared to challenge Catholic doctrine and in 1542, established the
Roman Inquisition to enforce its edicts with torture and execution.
-
-
- Thus Bruno entered a world in ferment. In 1563, Bruno
entered the monastery of St Dominic, where he came to the notice of church
authorities for his unorthodox religious views. He used his time as a novitiate
to acquaint himself not only with the philosophical works of the ancient
Greeks but also his more contemporary European thinkers. It was at this
time that he first encountered the work of Copernicus, which was to have
such a profound impact on his life.
-
-
- Bruno took holy orders in 1572 but then left the order
in 1576 after travelling to Rome. He had been caught reading philosophical
texts annotated by the Dutch humanist philosopher Erasmus and escaped before
being denounced to ecclesiastical authorities. He spent the rest of his
life until his capture wandering Europe discussing and promoting his philosophical
ideas.
-
-
- After three years in Italy he went to Geneva, which was
then dominated by the Protestant sect led by Calvin. He soon came into
conflict with academic authorities when he published a pamphlet stating
that a local Professor of Philosophy had made 20 errors in one lecture.
He was imprisoned by the Calvinist authorities and only released after
withdrawing the offending publication. Twenty six years before, the Calvinists
had burnt Servetus, a Spanish doctor, geographer and man of letters, at
the stake for his scientific views.
-
-
- Bruno then traveled to Toulouse in France, where he lectured
on Aristotle's De anima and wrote a book on mnemonics"systems of memory
training. He arrived in Paris by 1581, where he came to the attention of
King Henry III who was attracted by his reputation of having a prodigious
memory. The King found a position for him at the College de France after
he had been forbidden entry to the Sorbonne by ecclesiastical authority.
-
-
- During his stay in Paris he wrote three books, two on
mnemonics and a play entitled The Torch-Bearer by Bruno the Nolan, Graduate
of No Academy, Called the Nuisance. In this play Bruno described his time
in the Dominican convent in Naples and presented a withering indictment
of the church. Giovanni Gentile's commentary on the play describes Bruno's
characterisation of the church as follows: "You will see, in mixed
confusion, snatches of cutpurses, wiles of cheats, enterprises of rogues;
also delicious repulsiveness, bitter sweets, foolish decisions, mistaken
faith and crippled hopes, niggard charities, judges noble and serious for
other men's affairs with little truth in their own; virile women, effeminate
men and voices of craft and not of mercy so that he who believes most is
most fooled"and everywhere the love of gold."(5)
-
-
- Bruno was forced to leave France in 1583 and travelled
to England where his three-year stay proved to be one of the most fruitful
periods of his life. He was introduced into a society that craved all forms
of Italian learning and already had a considerable Italian and foreign
exile community. Many had fled to avoid persecution for unorthodox philosophical
and religious ideas. Bruno held discussions with Queen Elizabeth I, who
was attracted by the prospect of discussing philosophical matters directly
in Italian. He quickly attracted a number of intellectuals who eagerly
discussed the philosophical ideas of the time.
-
-
- In England, Bruno published six books, all in Italian,
fully elaborating his philosophical ideas for the first time. He was one
of the first philosophers to discuss scientific issues in the vernacular.
The very act of publishing in Italian was an open challenge to the Church,
which sought to maintain Latin as the language of intellectual discourse
and so limit the wider dissemination of ideas. Copernicus' groundbreaking
work had been published only in Latin. So afraid were Bruno's printers,
that not one of them identified themselves in his printed texts.
-
-
- Bruno's view of the universe
-
-
- Bruno's cosmology is outlined in The Ash Wednesday Supper,
Cause, Principle and Unity and On the Infinite Universe and Worlds, which
represent a brilliant anticipation of subsequent scientific and philosophical
developments. In fact in some respects the conclusions Bruno arrived at
by bold intuition surpassed the work of his successors such as Galileo
and Kepler. The works are in the form of dialogues, where Bruno's characters
argue various philosophical positions from different points of view, one
representing Bruno himself.
-
-
- In The Ash Wednesday Supper Bruno was one of the first
to argue for the existence of an infinite universe, which contained an
infinite number of worlds similar to the Earth. In doing so, he rejected
the limits of the Copernican system, which posited a finite universe limited
by a fixed sphere of stars just beyond the solar system. He argued that
the sun was not the centre of the universe, saying that if the sun were
observed from any of the other stars it would appear no different from
them. Bruno even speculated that the other worlds would be inhabited.
-
-
- German philosopher Ernst Cassirer explained the significance
of Bruno's conception of an infinite universe as follows: "This doctrine
... was the first and decisive step toward man's self-liberation. Man no
longer lives in the world of a prisoner enclosed within the narrow walls
of a finite physical universe. He can traverse the air and break through
all the imaginary boundaries of the celestial spheres which have been erected
by a false metaphysics and cosmology. The infinite universe sets no limits
to human reason; on the contrary, it is the great incentive of human reason.
The human intellect becomes aware of its own infinity through measuring
its powers by the infinite universe."(6)
-
-
- Bruno's other three works published in England, The Expulsion
of the Triumphant Beast, Cabal of the Cheval Pegasus and On Heroic Frenzies
contain a biting critique of the Counter Reformation. Italian historian
Hilary Gatti in her book Giordano Bruno and Renaissance Science observed:
"The sense of these final Italian works, in my opinion, is ... to
be found in a transition from an intellectual sphere dominated by a vision
of the world in essentially theological terms to an intellectual sphere
dominated by a vision of the world in essentially philosophical terms.
In this passage from theology to philosophy all forms of revealed religion
receive harsh treatment, but above all the Christian religion that dominated
the life and culture of the Europe of the sixteenth century, often through
violence and oppression."(7)
-
-
- It was in England that Bruno had his most profound impact.
His views were discussed in intellectual circles and the arguments presented
in his various books give a flavour of the contemporary discussion. Two
leading scientists, William Gilbert and Thomas Harriot, became leading
proponents of Bruno's cosmological views. Gilbert, whose De Magnete (1600)
stood as a basic text on magnetism until the 19th century, was prominent
in a grouping that discussed scientific issues. He was particularly interested
in developing his magnetic theories in relation to Bruno's cosmological
views.
-
-
- Harriot was a noted mathematician and astronomer, who
was thought to have discovered sunspots before Galileo. Harriot exchanged
letters with Kepler in 1608 discussing Bruno's conception of an infinite
universe, which Kepler was to reject. Harriot was one of the scientists
who were cultivated by the Ninth Earl of Northumberland"a devoted
follower of Bruno. Northumberland had an extensive library of Bruno's works,
which he made available to the scientists in his circle.
-
-
- Bruno was forced to return to France because of the decline
in the fortunes of his patron, the Marquis de Mauvissiere, with whom he
had travelled to England. He produced three works on his return to Paris
but was forced to leave after his challenge to debate all comers on the
topic One Hundred and Twenty Articles on Nature and the World resulted
in him being set upon by supporters of the church . He then travelled to
Germany, where he resided in Wittenberg and Marburg until 1588. He was
forced to leave Marburg after coming into conflict with the Lutheran authorities,
then wandered Europe"Prague, Helmstedt, Frankfurt and Zurich.
-
-
- In 1591 Bruno returned to Italy after being invited by
the Venetian nobleman Zuane Mocenigo to educate the aristocrat in mnemonics.
Mocenigo subsequently denounced him to the Inquisition. Bruno was arrested
on May 23, 1592, cross-examined on his philosophical works and on January
27, 1593 handed over to the Inquisition in Rome on the direct request of
the Papal Nuncio, Taverna, acting on behalf of Pope Clement VIII.
-
-
- During his detention in Rome he was interrogated on all
aspects of his life and his philosophical and theological views over a
period of seven years. On February 15, 1599 the Inquisition charged Bruno
with eight specific acts of heresy, which the church has not revealed to
this day. According to the limited documents available, Bruno was indicted
for his "atheistic" views and for the publication of The Expulsion
of the Triumphant Beast. He refused to recant.
-
-
- The Inquisition delivered its verdict on January 20,
1600, stating: "We hereby, in these documents... pronounce sentence
and declare the aforesaid Brother Giordano Bruno to be an impenitent and
pertinacious heretic, and therefore to have incurred all the ecclesiastical
censures and pains of the Holy Canon... We ordain and command that thou
must be delivered to the Secular Court... that thou mayest be punished
with the punishment deserved, though we earnestly pray that he (the Roman
Governor) will mitigate the rigour of the laws concerning the pains of
thy person, that thou mayest not be in danger of death or of mutilation
of thy members.
-
-
- "Furthermore, we condemn, we reprobate and we prohibit
all thine aforesaid and thy other books and writings as heretical and erroneous,
containing many heresies and errors, and we ordain that all of them which
have come or may come in future into the hands of the Holy Office shall
be publicly destroyed and burned in the square of St. Peter before the
steps and that they shall be placed upon the Index of Forbidden Books."(8)
-
-
- Despite the false note of concern about Bruno's physical
well-being, the Inquisition's verdict was a death sentence. Bruno was defiant
to the end. Gaspar Schopp of Brelau, a recent convert to Catholicism and
a witness to the sentencing, reported that Bruno exclaimed on hearing the
sentence: "Perchance you who pronounce my sentence are in greater
fear than I who receive it."(9)
-
-
- The Holy Inquisition and its tormenters are remembered
only as symbols of arch-reaction. But Bruno has stood the test of time.
An examination of his life reveals a true Renaissance man with a passionate
interest in all aspects of human learning, who participated with great
energy and determination in the intellectual turbulence of his times. His
insights made an important contribution to the ideas that laid the basis
for modern science. His stubborn refusal to bow to the authority, power
and repressive apparatus of the Roman Catholic Church, the most powerful
institution of his day, will no doubt be an inspiration for generations
to come.
-
-
- The German philosopher Georg Hegel summed up the generation
of thinkers to which Bruno belonged in his Lectures on the History of Philosophy:
"These men felt themselves dominated, as they really were, by the
impulse to create existence and to derive truth from their very selves.
They were men of vehement nature, of wild and restless character, of enthusiastic
temperament, who could not attain to the calm of knowledge. Though it cannot
be denied that there was in them a wonderful insight into what was true
and great, there is no doubt on the other hand that they revelled in all
manner of corruption in thought and heart as well as in their outer life.
There is thus to be found in them great originality and subjective energy
of spirit; at the same time the content is heterogeneous and unequal, and
their confusion of mind is great. Their fate, their lives, their writings"which
often fill many volumes"manifest only this restlessness of their being,
this tearing asunder, the revolt of their inner being against present existence
and the longing to get out of it and reach certainty. These remarkable
individuals really resemble the upheavals, tremblings and eruptions of
a volcano which has become worked up in its depths and has brought forward
new developments, which as yet are wild and uncontrolled."(10)
