Background: The New
Consideration of Nature
The Renaissance, as an age of transition, was
not conducive to the building of great
philosophical systems. It contained, in germinal
form, the directive ideas of modern times, but
under the guise of the past. Thinkers preferred to
write in ancient Latin, and the style of their
writing is also archaic. Under this external
aspect, which smacks of antiquity, are hidden the
signs of the next age.
The greatest representatives of thought, in the
order of time, are Nicholas
of Cusa, Telesio,
Bruno, and Campanella;
the most important is Bruno. In the thought of all
these men there is a new view of nature, in which
nature is considered immanently, according to the
forces inherent in it, and is accessible to
experience and reason. These forces are considered
as living ones, vital spirits, demons; everything
is animate; the physical world has a soul.
It is necessary to investigate these animate
forces, for it is on the basis of their activity
that all events can be explained. It is because of
this desire to bring into subjection the occult
forces of nature that during the Renaissance we
find so widely diffused the science of "magic,"
which professes to know the good and evil spirits
of nature, and to make them allies in good and evil
enterprises.
Also characteristic are alchemy, with its
objective of discovering the philosophical stone
which can change everything into gold; and
medicine, with its hope of finding the panacea of
evil by uncovering the common animating force of
the universe. This is a charlatan school, to be
sure, but it indicates the tendency of some of the
chief exponents of the age to explain nature
through the forces imbedded in it.
Hence we see Neo-Platonic tendencies, and the
Neo-Platonic thinkers mentioned above. Although
Neo-Platonism, logically developed, leads to
pantheism, the thinkers of the Renaissance, with
the exception of Bruno, are not pantheists. Without
any logical foundation they still affirm
transcendency, but this more from faith than from
conviction.
Now to the
Philosophy of Giordano Bruno
I.
Life and Works
Bruno was born at Nola 1548 and at the age of
fifteen or sixteen entered the Catholic Dominican
order in Naples. Falling under suspicion of heresy,
he was cast out of the Order, and began a disturbed
life of wandering, during which he roamed over half
of Europe. He was at Geneva, Paris, Oxford,
Frankfurt, everywhere teaching and writing and
engaging in heated controversy.
Invited by the Venetian nobleman Giovanni
Mocenigo, who wished to study Bruno's theory of
memory-training, he went to Venice. There he was
denounced as a heretic to the tribunal of the
Inquisition by the very nobleman who had sponsored
him.
At Venice, during the course of his trial, Bruno
acknowledged that he had fallen into heresy and
declared himself disposed to amend. Consigned by
the Republic of Venice to the Inquisition in Rome,
he was again subjected to trial.
This time he refused to retract and hence was
condemned to death as an obstinate heretic. The
sentence of death was carried out at Rome on
February 17, 1600.
Bruno's principal works are: Della causa,
principio, ed uno (Concerning Cause, Principle,
and Unity); Del' infinito, universo e mondi
(On the Infinite, the Universe and the World);
Eroici furori (Heroic Furors); De immenso
et innumerabilibus (On the Boundless and the
Innumerable); De monde, numero, et figura
(On the Monad, the Number, and the Figure).

Doctrine Concerning the Universe
Elements of the speculation of Heraclitus,
Parmenides, Democritus, and the Stoics, together
with the doctrine of Neo-Platonic emanations and
Nicholas of Cusa's
theory of the coincidence of opposites, as well as
the new heliocentric theory of Copernicus nurtured
the thought of Bruno. Under the apparent confusion
of his teaching lies the unity and organic
wholeness of monistic immanentism, of which Bruno
was the principal protagonist during the
Renaissance period.
According to Bruno, the universe is infinite,
full of a plurality of heliocentric solar systems
which are broken up and recomposed according to the
theory of Democritus. The fundamental principles of
the universe are two: matter, the passive
principle; and the soul, the active principle. Both
represent two aspects of a single substance, two
indistinguishable powers of a single principle, in
which they are reconciled and united, and in which
their differences are annulled, according to the
principle of coincidence of opposites of Nicholas
of Cusa.
"All things are one," says Bruno. The soul of
the universe is conceived of as intelligent, the
ordinator of the world itself, the interior force
of everything. Such a force is not transcendent,
but immanent; it adheres in things. It is God,
conceived of as "Natura naturans," producing all
and ordaining all to its end; it is infinite. The
world, the work of "Natura naturans," is "Natura
naturata," which, as the effect of an infinite
cause, is also infinite.
Individual souls (and not only the human soul,
but the soul of every individual essence, since for
Bruno everything is animate) are the passing shades
of the eternal becoming of the world. Bruno calls
them monads. Birth is the individuation of the
infinite in the finite; death indicates the return
of the finite to the infinite.
Thus far the concept of Bruno is decidedly
monistic immanentism. Nevertheless, besides the
mens imbedded in all things, that is, the
soul of the world immanent in the universe, Bruno
admits also the mens super omnia, that is,
God, who transcends the world. But this God (quite
different from the Christian God, because the world
does not depend upon Him) is the object of faith
and not of science; Bruno admits this in order to
overcome the materialistic pantheism of his
system.
In such a materialistic concept of the universe,
any positive religion, including Christianity, is
impossible. Religion for Bruno has practical but
not theoretical value; it is an efficacious means
of educating the ignorant masses through the
symbolism of forms. Consequently, Bruno's thought
necessarily conflicts with the doctrine of the
Catholic Church.
Bruno's moral system is opposed to the teachings
of the Catholic Church, but is consistent with his
naturalistic immanentism. The end which man must
realize is limited to the present life; it consists
in the participation of the individual in the life
of the universe. Virtue is not renunciation or
asceticism but "heroic furor" -- that is, the
joyous consciousness of one's own excellence and of
one's own participation in the life of the
universe.
The system of Bruno is a theoretical expression
of Humanism, and his thought was to have a great
influence on modern philosophy.
