Idols
Which Beset Man's Mind
by Francis Bacon
Man, being the servant and interpreter of
nature, can do and understand so much and so much
only as he has observed in fact or in thought of
the course of nature: beyond this he neither knows
anything nor can do anything.
***
Human knowledge and human power meet in one; for
where the cause is not known the effect cannot be
produced. Nature to be commanded must be obeyed;
and that which in contemplation is as the cause is
in operation as the rule.
***
There are and can be only two ways of searching
into and discovering truth. The one flies from the
senses and particulars to the most general axioms,
and from these principles, the truth of which it
takes for settled and immovable proceeds to
judgment and to the discovery of middle axioms! And
this way is now in fashion. The other derives
axioms from the senses and particulars, rising by a
gradual and unbroken ascent, so that it arrives at
the most general axioms last of all. This is the
true way, but as yet untried.
The understanding left to itself takes the same
course (namely, the former) which it takes in
accordance with logical order. For the mind longs
to spring up to positions of higher generality,
that it may find rest there; and so after a little
while wearies of experiment. But this evil is
increased by logic, because of the order and
solemnity of its disputations.
The understanding left to itself, in a sober,
patient, and grave mind, especially if it be not
hindered by received doctrines, tries a little that
other way, which is the right one, but with little
progress; since the understanding, unless directed
and assisted, is a thing unequal, and quite unfit
to contend with the obscurity of things.
Both ways set out from the senses and
particulars, and rest in the highest generalities;
but the difference between them is infinite. For
the one just glances at experiment and particulars
in passing, the other dwells duly and orderly among
them. The one, again, begins at once by
establishing certain abstract and useless
generalities, the other rises by gradual steps to
that which is prior and better known in the order
of nature.
***
The axioms now in use, having been suggested by
a scanty and manipular experience and a few
particulars of most general occurrence, are made
for the most part just large enough to fit and take
these in: and therefore it is no wonder if they do
not lead to new particulars. And if some opposite
instance, not observed or not known before, chance
to come in the way, the axiom is rescued and
preserved by some frivolous distinction; whereas
the truer course would be to correct the axiom
itself.
The conclusions of human reason as ordinarily
applied in matter of nature, I call for the sake of
distinction Anticipations of Nature (as a
thing rash or premature). That reason which is
elicited from facts by a just and methodical
process, I call Interpretation of
Nature.
Anticipations are a ground sufficiently firm for
consent; for even if men went mad all after the
same fashion, they might agree one with another
well enough.
For the winning of assent, indeed, anticipations
are far more powerful than interpretations; because
being collected from a few instances, and those for
the most part of familiar occurrence, they
straightway touch the understanding and fill the
imagination; whereas interpretations on the other
hand, being gathered here and there from very
various and widely dispersed facts, cannot suddenly
strike the understanding; and therefore they must
needs, in respect of the opinions of the time, seem
harsh and out of tune; much as the mysteries of
faith do.
In sciences founded on opinions and dogmas, the
use of anticipations and logic is good; for in them
the object is to command assent to the proposition,
not to master the thing.
Though all the wits of all the ages should meet
together and combine and transmit their labours,
yet will no great progress ever be made in science
by means of anticipations; because radical errors
in the first concoction of the mind are not to be
cured by the excellence of functions and remedies
subsequent.
It is idle to expect any great advancement in
science from the superinducing and engrafting of
new things upon old. We must begin anew from the
very foundations, unless we would revolve forever
in a circle with mean and contemptible
progress.
The honour of the ancient authors, and indeed of
all, remains untouched; since the comparison I
challenge is not of wits or faculties, but of ways
and methods, and the part I take upon myself is not
that of a judge, but of a guide.
This must be plainly avowed: no judgment can be
rightly formed either of my method or of the
discoveries to which it leads, by means of
anticipations (that is to say, of the reasoning
which is now in use); since I cannot be called on
to abide by the sentence of a tribunal which is
itself on its trial.
Even to deliver and explain what I bring forward
is no easy matter; for things in themselves new
will yet be apprehended with reference to what is
old.
It was said by Borgia of the expedition of the
French into Italy, that they came with chalk in
their hands to mark out their lodgings, not with
arms to force their way in. I in like manner would
have my doctrine 'enter quietly into the minds that
are fit and capable of receiving it; for
confutations cannot be employed, when the
difference is upon first principles and very
notions and even upon forms of demonstration.
One method of delivery alone remains to us;
which is simply this: we must lead men to the
particulars themselves, and their series and order;
while men on their side must force themselves for
awhile to lay their notions by and begin to
familiarise themselves with facts.
The doctrine of those who have denied that
certainty could be attained at all, has some
agreement with my way of proceeding at the first
setting out; but they end in being infinitely
separated and opposed. For the holders of that
doctrine assert simply that nothing can be known; I
also assert that not much can be known in nature by
the way which is now in use. But then they go on to
destroy the authority of the senses and
understanding; whereas I proceed to devise and
supply helps for the same.
The idols and false notions which are now in
possession of the human understanding, and have
taken deep root therein, not only so beset men's
minds that truth can hardly find entrance, but even
after entrance obtained, they will again in the
very instauration of the sciences meet and trouble
us, unless men being forewarned of the danger
fortify themselves as far as may be against their
assaults.
There are four classes of Idols which beset
men's minds. To these for distinction's sake I have
assigned names, -- calling the first class Idols
of the Tribe; the second, Idols of the
Cave; the third, Idols of the
Market-place; the fourth, Idols of the
Theatre.
The formation of ideas and axioms by true
induction is no doubt the proper remedy to be
applied for the keeping off and clearing away of
idols. To point them out, however, is of great use;
for the doctrine of Idols is to the Interpretation
of Nature what the doctrine of the refutation of
Sophisms is to common Logic.
The Idols of the Tribe have their foundation in
human nature itself, and in the tribe or race of
men. For it is a false assertion that the sense of
man is the measure of things. On the contrary, all
perceptions as well of the sense as of the mind are
according to the measure of the individual and not
according to the measure of the universe. And the
human understanding is like a false mirror, which,
receiving rays irregularly, distorts and discolours
the nature of things by mingling its own nature
with it.
The Idols of the Cave are the idols of the
individual man. For every one (besides the errors
common to human nature in general) has a cave or
den of his own, which refracts and discolours the
light of nature; owing either to his own proper and
peculiar nature; or to his education and
conversation with others; or to the reading of
books, and the authority of those whom he esteems
and admires; or to the differences of impressions,
accordingly as they take place in a mind
preoccupied and predisposed or in a mind
indifferent and settled; or the like. So that the
spirit of man (according as it is meted out to
different individuals) is in fact a thing variable
and full of perturbation, and governed as it were
by chance. Whence it was well observed by
Heraclitus that men look for sciences in their own
lesser worlds, and not in the greater or common
world.
There are also Idols formed by the intercourse
and association of men with each other, which I
call Idols of the Market-place, on account of the
commerce and consort of men there. For it is by
discourse that men associate; and words are imposed
according to the apprehension of the vulgar. And
therefore the ill and unfit choice of words
wonderfully obstructs the understanding. Nor do the
definitions or explanations wherewith in some
things learned men are wont to guard and defend
themselves, by any means set the matter right. But
words plainly force and overrule the understanding,
and throw all into confusion, and lead men away
into numberless empty controversies and idle
fancies.
Lastly, there are Idols which have immigrated
into men's minds from the various dogmas of
philosophies, and also from wrong laws of
demonstration. These I call Idols of the Theatre;
because in my judgment all the received systems are
but so many stage-plays, representing worlds of
their own creation after an unreal and scenic
fashion. Nor is it only of the systems now in
vogue, or only of the ancient sects and
philosophies, that I speak; for many more plays of
the same kind may yet be composed and in like
artificial manner set forth; seeing that errors the
most widely different have nevertheless causes for
the most part alike. Neither again do I mean this
only of entire systems, but also of many principles
and axioms in science, which by tradition,
credulity, and negligence have come to be
received.
