12 Descartes, Meditations IV [T]here is no reason to marvel at the
fact that God should bring about certain things the reasons of which I do not
understand. Nor is his existence
therefore to be doubted because I happen to experience other things of which
I fail to grasp why and how he made them. – Descartes Meditations IV By the close of Meditations III, Descartes was
convinced that he had established the existence of God beyond any possible
doubt. Since God is infinitely
perfect, whereas deception is a product of weakness and wickedness, it
follows that God would not deceive me.
Since God’s perfections involve benevolence and power, it also follows
that he would not allow any other being to deceive me. If I get things wrong — as undoubtedly I do
— then it cannot be because I have been deceived by God or some other being. It must rather be because I have made some
sort of mistake. Error is not to be
attributed to trickery or deception, but to my own improper use of my
faculties. The principal job of Meditations IV is to uncover what I do
to bring myself to err, and so come up with recommendations for avoiding
those mistakes in the future. In the process of
doing this job, Meditations IV also
goes some way to explain why God would have made me capable of falling into
error, notwithstanding that he is perfectly good. But it only goes some way, not all the way.
Error is not Descartes’s
version of the problem evil (evil for someone who doubts the existence of an
external world and all it contains, such as plagues and earthquakes and human
wickedness in action). Descartes did
not consider the fact that I make mistakes to be in any way a challenge to
the belief in God. He took it to be
obvious that I do make mistakes, but also beyond doubt that God exists. From these two facts he drew the conclusion
that God must have good reasons for making me capable of falling into
error. He tried to understand those
reasons well enough to be able to ascertain and avoid the causes of
error. But he did not consider it
important to provide a full vindication of God’s practice in making me
capable of error. The meditation accordingly
concludes by leaving God’s full motives for making me as I am something of a
mystery. QUESTIONS ON THE Note: In the second sentence of Meditations IV Descartes made a reference to
directing his thought away from things that can be imagined. It would have been more accurate to
translate him as talking about directing his thought away from things that
can be imaged or pictured, including the things shown to us by our senses.

God could have made me more cautious, so that
my caution would restrain me from ever willing to affirm something I do not
clearly and distinctly understand. But
he didn’t. Can he be faulted for that? Why or why not? NOTES ON THE Descartes opened Meditations IV by recalling a classic
solution to the problem of evil, that proposed by Augustine of Hippo. Augustine maintained that evil is not a
real, positive thing that is created by God, but merely the privation of
good. Human moral evil, for example,
is not the product of a bad character implanted in certain people by God, but
rather results from ignorance and weakness.
Neither ignorance nor weakness is created by God. God only creates wisdom and strength. But because God only puts finite amounts of
wisdom and strength into his creatures, the amount by which their wisdom and
strength falls short of perfection appears to us as a quantity of ignorance
and weakness. The appearance is merely
an appearance, however. Ignorance and
weakness are not something but nothing, or rather, a lack or deficiency in
things. This solution applies broadly. Augustine declared that all that God
created is good and that all evil is merely the appearance that results from
the fact that God has not filled everything to bursting with good by only
creating rival deities. We have no
right to blame God for doing this, because God was under no obligation to
create anything at all, much less everything that he appears to have created. Accordingly, we ought to praise God for
being so gracious as to create as much as he did rather than complain that he
did not do more. Descartes briefly
wondered whether this blunt solution to the problem of evil might also answer
his question about the cause of error.
God is not restricted to creating only totally perfect beings. Were that the case, the universe could
contain only one thing: God himself (if we accept the standard view that it
is part of God’s perfection that there be only one of him). So suppose God has decided to add to the
bounty of the universe by creating a variety of different beings. These beings differ from one another in
possessing all the different degrees and kinds of reality or perfection that
can be supposed to exist between God himself (=total perfection) and utter
nothingness (=lack of any real or perfect quality whatsoever). Then it is not improper that we should have
been given only limited knowing powers.
On the contrary, some beings must have been created with our specific
set of limitations, and we are those beings.
For us, the only alternative is not to have been created at all. Meditating on himself,
Descartes declared that he seems to himself to occupy an intermediate
position between God, who is the sum total of all perfection, and nothingness
or the lack of all perfection. Might
we therefore attribute error simply to this fact, that we are not all-perfect
and so do not have perfect capacities of judgment? After some
consideration Descartes decided that, while quite correct as a way of
accounting for some kinds of evil, this Augustinian reply is inadequate to
explain the cause of mistaken judgment.
If God makes us limited by denying us knowledge of certain things,
that merely makes us ignorant. It does
not make us mistaken. For us to make
mistakes, our cognitive faculties can’t just fail to function. They have to function improperly. This is not something we would expect. The more expert an artisan is, the better
the artisan’s products work. They may
not do everything. But they should do
what they were designed to do perfectly.
An expert clockmaker may not be expected to make a clock that displays
the date, or the quarter of the moon, or other such details. But whatever the clock was designed to
report should be reported perfectly.
Similarly, an artisan who makes a being capable of judgment should be
able to make the being so that it never makes mistakes in judgment, even if
it does not make judgments about all things. Descartes proceeded to
reiterate that this is no reason for doubting the existence of God. We are not asking how mistakes on our part
are compatible with the perfection of God because we have any doubt about
God’s existence. Rather, we want to
understand what causes our mistakes so that we can avoid them in the future. But the task is a daunting one. While we can be assured that God must have
had some good reason for making us as we are, we are finite beings who
probably cannot understand all the purposes that God had in mind in creating
things. (This is why, Descartes paused
to observe, it is useless to inquire about the “nature,” “ends,” or
“purposes” of things when doing physics.
We do not know enough about the mind of God to know those
things.) One reason why we might have
been made liable to make mistakes is that this constitution is somehow more
conducive to the perfection of the whole universe of which we are a
part. But if that is so, then our
situation is truly hopeless. Because
we don’t know anything about what exists in the world about us (and aren’t in
a position to learn before we discover the causes of error), we can’t begin
to conjecture about how we fit in with that world so as to make it more
perfect, and so can’t uncover the causes of error. But there is another,
more promising reason why we might have been made liable to make
mistakes. This is that this
constitution is somehow more conducive to the perfection of the little
universe that consists just of ourselves and the
collection of our ideas and abilities.
We can at least know ourselves and investigate them. Descartes therefore
determined to look within himself for the causes of error. In accord with the second rule of his
method, he proceeded by breaking his problem down into its most simple
parts. His problem concerns the
existence of false or mistaken judgment.
The power of judgment must therefore be broken down into its component
parts before proceeding any further. Descartes reflected
that all judgments consist of the affirmation or denial of a relation between
two or more ideas. The judgment that
all bodies are extended, consists of certain ideas, the ideas of body and
extension. But in addition to these
ideas we make an assertion concerning the existence of a relation or
connection between the objects of these ideas. We say that the one inheres in the other as
its property. Similarly, the judgment
that the sun melts wax but hardens clay consists of a number of ideas: the
sun, wax, clay, hardness, and softness.
But in addition to these ideas we make an assertion concerning the
existence of a certain relation or connection between the objects of these
ideas. We say that the third comes to
inhere in the second as an effect of the first. All our judgments are like this. They
include the perception of two or more ideas and the affirmation of a relation
of identity or containment or inherence or causality or some other such thing
that is taken to connect the objects of the ideas with one another. The ideas are perceived by the
understanding or the intellect (these are synonymous terms for Descartes). But the understanding does not judge. It just inspects each of the ideas on their
own and, as it were, sees what they contain.
The affirmation of a connection or relation between the ideas is an
activity and, like all activities, belongs to the will. Descartes proceeded to
consider each of these two capacities.
He decided that neither of them, considered on its own, is at all
defective. The understanding is
limited. We do not grasp all the ideas
that there are to be grasped, and those that we do grasp are not all clearly
and distinctly perceived, but rather are often perceived with varying degrees
of confusion or even obscurity. But
though the understanding is limited it is not defective. While it does not perceive all ideas or
perceive those it does with equal clarity and distinctness, it never
represents what it perceives other than as it perceives it. So there is no defect in its operation. Having considered the
understanding, Descartes turned to the will and noted that not only is it not
defective, but it is not even limited. This may seem questionable, especially
to those who have not been able to get their way recently. But when Descartes spoke about the power of
the will all he had in mind is the power to make assertions and denials and
to express desire and aversion, not the power to make what you assert true or
what you deny false or what you desire real or what you fear unreal. All of these things have to do with what
ideas of sensation are produced in us or even, more remotely than that, with
what is supposed to exist in an external world outside us, whereas Descartes
considered the will only as a power to affirm or deny or express desire or
aversion, not to bring the objects of affirmation or denial or desire or
aversion about. Introspection appears
to indicate that this expressive power is not constrained by any external
factors. A prisoner shut up in a small
cell, fed bread and water, and forced under threat of torture to recite
prayers may not be able to move freely or eat a fine meal or express
atheistic sentiments, but no external factors can prevent the prisoner from
willing to be free, desiring a good meal, or judging that there is no God. However, though
Descartes maintained that our wills are not determined by any external force,
he immediately proceeded to add that they can be determined by various
internal factors, including reason and Grace.
Indeed, he went so far as to maintain that under certain circumstances
the understanding can exercise an absolute compulsion over the will in
matters of assertion and denial, and can compel it to judge a certain
way. This is the case when we
understand ideas so thoroughly that we see the connection between them. In the case of the judgment that all bodies
are extended, for instance, a clear and distinct perception of the idea of a body,
such as the piece of wax of Meditations
II, reveals that the idea of extension is the one idea that is essentially
contained in the idea of body. Again,
in the case of the judgment that two plus three is equal to five, a clear and
distinct perception of the idea of any two and any three things reveals that
the two groups taken together make five things. In these cases, Descartes supposed, what
the understanding so clearly and distinctly perceives leaves no room for the
will to judge otherwise, but compels the will to judge accordingly and assert
that the relation of inherence connects extension with body, and that the
relation of equality connects five with two collected together with
three. It is only in cases where the
understanding does not clearly and distinctly perceive a connection between
ideas that the will has the power to either affirm or deny or refrain from
making any judgment whatsoever on the matter. But though in these
cases the understanding determines the will and judgment, Descartes still
maintained that the will is free.
Indeed, he went so far as to insist that in these cases it is free in
the highest sense. This sounds
paradoxical but the paradox is merely apparent. What makes my will free, as
Descartes saw it, is that it is not constrained by any external force. But my
understanding is not an external force.
It is part of me (indeed, the noblest part of me and what I most truly
am). I am one thinking being, not a
bundle of many different thinking beings.
I, one and the same being, both understand and will. And if I understand a certain thing, and my
will moves in accord with my understanding, that is an indication of my freedom as an understanding being.
After all, were I to understand something, and were my will not to respond
accordingly, we would think that something is wrong and that I do not have
control over my own will. We can contrast cases
where our wills are determined either by our understanding or by some other
internal factor, such as passion, natural impulse, or Grace, with cases where
our wills are not determined at all because nothing in us inclines us in any
particular way and we are totally indifferent to the choice put before us
(think of the case of someone being asked to pick a dime from a pile of
dimes, or an egg from a crate of eggs).
In Descartes’s view, cases of the latter
sort are a result of one or the other of two things: ignorance or
impotence. When we feel indifferent
about a choice, it is because we do not know what the full consequences will
be or because we think that whatever we choose, it will not change
anything. Choices made in such
circumstances are still free, but Descartes considered them to be lesser
expressions of freedom because they do not realize any wants we have or any
decisions we have made. Because there is nothing in us guiding the choice, it
is as if the choice is not really due to us, even though we are the ones that
are making it. This is why, even
though it may at first seem paradoxical, choices that are determined by
something in us, like our understanding, are truly free whereas choices that
are not determined by anything in us are not really ours and so express a
lower form of freedom. Having completed this
analysis of the faculties involved in judgment, Descartes was finally in a
position to offer a theory of the nature and causes of error in
judgment. He attributed error to the
imbalance that exists between the will and the understanding. The understanding, being finite, is not
able to clearly and distinctly perceive everything that there is to all of
its ideas and hence cannot determine all of the relations that hold between
its ideas. Consequently it is not able
to determine judgment in all cases.
But since the will is unlimited, it retains the power of affirmation
and denial even in the absence of a clear and distinct perception on the part
of the understanding. Consequently, rather than refrain from judging on the
grounds that the evidence is incomplete, it can run ahead of what is clearly
and distinctly perceived and make a judgment without due consideration. It is in these cases, Descartes claimed,
that we are led into error. With this theory of
the causes of error in place, Descartes was in a position to make a recommendation
about how to avoid error in the future.
Since error arises when the will runs ahead of the understanding and
produces a judgment in the absence of being compelled to do so by a clear and
distinct perception, we need merely turn the power of will around and use it to
refrain from making any such judgments.
We ought, in other words, to restrict ourselves to only making
judgments about those matters that are clearly and distinctly perceived. The closest Descartes
came to giving a definition of clear and distinct perception is in the
following passage from his Principles
of Philosophy. I call a perception “clear” when it is
present and accessible to the attentive mind — just as we say that we see
something clearly when it is present to the eye’s gaze and stimulates it with
a sufficient degree of strength and accessibility. I call a perception “distinct” if, as well
as being clear, it is so sharply separated from all other perceptions that it
contains within itself only what is clear. [Principles I 45, AT VIIIa 21-22] Provisionally, we can
say that an idea is obscure when it
is present only in part or not easily distinguished from its surroundings, and clear when
it is not obscure. An idea is distinct when it is possible to form
separate ideas of its individual parts or the simple natures that go to make
it up, confused when the parts are
muddled together or the simple natures have not been adequately attended to
and distinguished from one another. A judgment is
justified when we can see one idea clearly or distinctly enough to find the
other idea contained inside of it or see some larger, containing idea clearly
or distinctly enough to find two or more ideas related to one another within
the containing idea in the appropriate way. Judgment is in these cases
compelled by the understanding because we cannot deny that we are seeing what
we see. Fortunately, we do not
need to worry about making a higher-order judgment about whether a given
object satisfies the criteria for being clearly and distinctly perceived — a
situation that, were it to arise, would precipitate a vicious regress. This is because when a connection between
ideas is as a matter of fact clearly and distinctly perceived, the
understanding determines the will, so we are not able to do otherwise than
judge accordingly. In the absence of
clear and distinct perception, on the contrary, we always have the ability to
refrain from judging either way. The
difference between judging in accord with a clear and distinction on the part
of the understanding and judging in accord with a mere natural impulse is
therefore made clear by the fact that in the former case we cannot refrain
from judging, whereas in the latter we can.
And if we retain any residual doubts about whether we might be giving
in to a temptation to persist in juvenile preconceptions or succumb to mere
natural impulses, we need merely carefully consider what is clear and
distinct in our ideas. When we think that
we can’t tell whether our ideas of sensible qualities like colour or heat are
ideas of real, positive qualities or materially false ideas of nothing, we
can’t consider those qualities to be even so much as clear, much less
distinct. When we think that a whole
science exists describing the details of what is contained in our idea of
extension, namely, the science of geometry, we can’t help but judge that the
idea of extension is both clear and distinct, even if extended things may
only exist in our dreams and not outside of them. But might it still
have been a part of God’s plan to allow us to be deceived, even in matters
such as this? Descartes’s
next task was to establish, on the one hand, that his theory of the causes of
error is consistent with the fact that we have been created by a supremely
perfect being and, on the other hand, that his theory of the method for
avoiding error is underwritten by those same considerations. He had three observations to make on these
related questions. To begin with, he
noted that it is not incompatible with God’s goodness that our understandings
should be finite as long as those few things we are able to understand are
things we are able to understand correctly.
Artisans are under no obligation to put everything they can possibly
create into each of their artefacts, as long as the lack does not impede the
intended function of the artefact.
This remark has an important implication. It means that if our understandings clearly
and distinctly perceive a certain relation between ideas, then that
perception must be correct, and any judgment affirming it could not be in
error. Otherwise, our understanding would not just be limited in its
operations, which is compatible with the goodness of God, but defective in
those operations, which is not compatible with the goodness of God and so
impossible, given what we have learned about God. Second, Descartes
noted that it is not incompatible with God’s goodness that our wills be
perfectly free. The notion of a
partial will really makes no sense. To
say that the will is constrained in any way is to say that we do not have a
will, but are determined. So when
creating us God really just had a choice between giving us no free will or an
infinite free will, and we can hardly complain that we do not approve of the
choice he made. Taken in conjunction,
these two observations entail that the imbalance between the will and the
understanding is consistent with the perfection of our creator. Given that God determined to create beings
with finite understandings, it is still better that those beings should have
some free will than none at all. And
since there can be no partial attributions where the will is concerned, this
means that finite beings with imbalanced will and understanding are better
than finite beings with no will at all. But it is still
possible to wonder why an all-perfect creator, concerned that its creations
would not fall into error, would not have amended our constitution by giving
us some further capacity to prevent our wills from over-running our
understandings. God could have, for
instance, given us more cautious and hesitant characters, so that we would
not be disposed to make hasty judgments.
This question motivated Descartes’s third
observation: that whatever else God might have done for us, he did not leave
us entirely at loose ends, but has already made us so that it is at least
possible for us to avoid error by simply using our freedom of will to
discipline ourselves to not let ourselves make judgments about matters that
we do not clearly and distinctly perceive.
He may not have made us instinctively disposed to do this. He may not have revealed that we need to
discipline ourselves to do it, the way he revealed the Ten Commandments to
Moses. But he at least gave us the
infinite free will that has the power to do this, and the intelligence to
discover the necessity of doing so for ourselves (as Descartes had just
done). God must have had only the best
reasons for not doing any more. At the same time, we
can be sure that he would not have done any less. Just as he cannot have created us with a
defective understanding, that would clearly and distinctly perceive what is
false, so he cannot have made us incapable of restricting our judgments to
what we truly perceive clearly and distinctly, particularly after serious
effort and frequent review. To have
made us so that we could fall into error with no hope of discovering and
correcting our mistake would make him a deceiver, which is impossible. The same would be true were God to allow
any other powerful being to impede the operations of our understanding in
this way. Consequently, we can remove
the demon deceiver objection. We are
now in a position to clearly and distinctly perceive that there is no
foundation to this objection — a position where our understanding of this
matter is so clear that it determines our wills to set this objection forever
aside. Whatever we clearly and
distinctly perceive to be true, and are accordingly compelled to judge to be
true, must in fact be true. We have arrived back
at the point we departed from midway through Meditations I, where Descartes resolved to deny anything that
could be coming to him only in a dream, but to accept those demonstrative
sciences, such as mathematics, geometry, and logic, that are not bound up
with a commitment to the existence of sensible things. We are no longer being asked to reject
anything in which we can find a shadow of a doubt. We are being asked only to accept what our
understanding compels us to accept, that is, what no exercise of the infinite
power of our free will allows us to overturn. ESSAY QUESTIONS AND RESEARCH PROJECTS Compare Descartes’s position on the freedom of the will, as
presented in Meditations IV with
Hobbes’s, as presented in Human nature
XII, and determine which is more plausible and which provides a more thorough
and adequate account of the phenomena of the will. Note that Hobbes authored the third set of
comments on Descartes Meditations
(like Arnauld, mentioned in the previous chapter,
Hobbes was one of the individuals whose comments were solicited by Mersenne and were bound in with the complete editions of
the Meditations). In his twelfth objection, Hobbes charged
that Descartes had merely assumed the freedom of the will without proof and
that his position is not obviously true, as it is denied by many, notably
Calvinists (i.e., those who believe in predestination and the possibility of
doing good only through Grace). Assess the adequacy of Descartes’s
reply to Hobbes on this matter. |
