I.
General Notions
Francis Bacon (picture)
was a man who was brilliant in many ways: as a
scientist, as a philosopher, and as an enthusiastic
innovator in the methods of science, which he
considered to be means for establishing the
dominion of man on earth ("regnum hominis"). Bacon
is remembered mostly for having worked out the
inductive method.
He began with such phenomena of nature as are
presented to us, but he intended to go beyond the
phenomenal data, to reach knowledge of the
form. Nature and form are
terms that recall to mind the metaphysics of
Aristotelio-Scholasticism. But, as used by Bacon,
these terms have a different meaning:
- Natures are the natural phenomena of
heat, sound, light, or of any other actual
object of the investigations of physical
science;
- Forms are the immanent laws of these
natures.
The metaphysical support for these natures and
forms is not treated by Bacon. The only metaphysics
consistent with a phenomenalistic physics is
mechanical atomism (Democritus - Descartes).
Therefore, the differences between phenomena depend
upon nothing more than the different positions of
atoms regulated by movement.
Even if we grant that Bacon's method leads to a
knowledge of what he calls the forms (the laws of
nature), such a knowledge will only indicate that
until the present day the phenomena were regulated
by such laws or forms. But this does not prove that
tomorrow these phenomena will obey the same laws.
In other words, Bacon does not give us a
metaphysics -- independent of the phenomena --
which would be the support of these same
phenomena.
It seems, however, that Bacon did not realize
the phenomenalistic consequences of his method, and
hence could still affirm that the traditional
metaphysical world exists alongside his phenomenal
world. The later philosophers of Empiricism showed
that this is an untenable position, and concluded
that all reality is pure phenomenon.

Life and Works
Francis Bacon was born in London in 1561. He
studied at Cambridge. After having spent some time
in France, he returned to his native land and with
the favor, first of Queen Elizabeth and then of
King James I, he rapidly rose to the highest
offices of state until in 1618 he became Lord
Chancellor and Baron Verulam. In 1621 he was named
Viscount St. Albans.
Accused of bribery and corruption during this
same year, he was tried and condemned to prison.
After receiving the King's pardon, he retired to
private live and dedicated himself completely to
his studies until the time of his death in
1626.
The principal work of Francis Bacon is
Instauratio magna scientiarum (The Great
Restoration of Learning), which was intended to
embrace the entire field of knowables, both
theoretical and practical. But of this vast work he
finished only the first and second parts: De
degnitate et augmentis scientiarum (Of the
Proficience and Advancement of Learning), and
Novum organum scientiarum (New Organ of
Learning). Bacon left only notes for what was to
have been the other parts of his monumental
work.
III.
"Instauratio Magna"
Bacon, a contemporary of Galileo and Descartes,
witnessed the first conquests of modern science,
the first inventions, the entry of England into the
ranks of the great nations. He became a most
enthusiastic admirer of science. For Bacon,
knowledge is power, and man's capacity to act is in
proportion to his knowledge. Science is not
theoretical and speculative, but practical. It was
to lead man to the discovery of the realm of
nature, and to allow him to establish over it the
"regnum hominis," the dominion of man.
But before man could dominate nature, he had to
obey her. He had to enter into her realm as a child
who listens in order to learn. Only after he knows
what nature contains can he become her master.
Ancient wisdom, based on the Organon of
Aristotle, was not
the proper means to practical discoveries. The
syllogism is good as a demonstrative form of
something one already knows, because the conclusion
is contained in the premises; but it does not allow
us to penetrate any new domain.
For the new science, a new way is necessary -- a
new organ ("novum organum") -- through which
discoveries will not be the work of chance, as in
the past, but the result of systematic experiments.
Thus an "instauratio ab imis fundamentis" of all
human knowledge is necessary -- a restoration of
human knowledge beginning at the root of things, as
a means of discovering the hidden possibilities of
nature.
IV.
"Novum organum"
Bacon's inductive method, which he sets forth in
his Novum organum, is composed of two parts:
the negative process ("pars destruens") and the
positive process ("pars construens"). This method
is in opposition to the Organon of
Aristotle, which was considered old because it it
an instrument of the deductive-syllogistic
method.
The negative process has the purpose of freeing
the mind of all prejudices and errors (called
idols by Bacon) which have penetrated it.
Such prejudices and errors Bacon divides into four
groups:
- (1) Idols of the tribe consist in
thinking of things and their relations by
analogy with man, that is, considering things as
actual and organized when such aspects do not
objectively exist, but are merely conceived by
man.
- (2) Idols of the cave derive from the
psychic formation of the individual, who knows
the things not in themselves, but only from
their subjective images, as in the case of
Plato's celebrated slaves imprisoned in the
cave.
- (3) Idols of the forum, or idols of
the marketplace, are derived from social
relationships and above all from the use of a
common language.
- (4) Idols of the theater are errors
coming from false philosophical systems which,
like the fables of the theater, are simply
fantastic.
The mind, liberated from all errors, can
undertake its positive work, the interpretation of
nature (phenomena); that is to say, it can come to
the knowledge of forms, of the laws regulating such
natures. This constructive process of Bacon's
method ("pars construens") is set up in three
different types of tables:
- (1) The table of presence ("tabula
praesentiae") lists all the cases wherein the
phenomenon exists whose formal cause is sought:
for instance, heat, which appears to be present
in fire, in the sun, etc.
- (2) The table of absence ("tabula
absentiae") lists all the cases in which the
phenomenon under analysis does not appear to be
present: there is no heat in the light of the
stars, of the moon, etc.
- (3) The table of degrees ("tabula
graduum") lists the increase and decrease of the
given phenomenon in one object or in different
objects. This third table, by leading to
knowledge of the law of movement of the
phenomenon, should bring us to know the formal
cause (law) of the phenomenon itself. It is not
always easy to arrive at a formulation of the
law of the form of movement. In such a case we
must be content with a temporary or working
hypothesis, and await new instances, new
experiments.
These are the principles, both positive and
negative, which Bacon proposes as the basis of
modern science and which should lead man to
conscious discoveries and hence to domination over
nature.
As we have already observed, the Baconian
method, based on experiences as they are offered to
our senses, can indicate what was the course of
nature and what it still is; but the method cannot
prove the necessity and the universality of any
laws. Furthermore, the forms or laws regulating
phenomena are physical facts, which in Bacon lack
metaphysical support, for the only data are matter
and the movement of matter; hence this method is
pure mechanism. Hobbes
developed this mechanistic viewpoint and proclaimed
materialism; Locke,
Berkeley and
Hume,
concentrating on the formal aspect, turned to
phenomenalism.
