Descartes overall objective in the Meditations is to question knowledge. To explore such
metaphysical issues as the existence of God and the separation of mind and body, it was
important for him to distinguish what we can know as truth. He believed that reason as
opposed to experience was the source for discovering what is of absolute certainty. In my
explication, I will examine meditation two in order to discover why knowledge was so
important to Descartes.Meditation One
The first meditation acts as a foundation for all those that follow. Here Descartes
discerns between mere opinion and strict absolute certainty. To make this consideration he
establishes that he must first “attack those principles which supported everything I
once believed.”(quote, paraphrase) He first examines those beliefs that require our
senses. He questions, whether our senses are true indicators of what they represent. By
inspecting our sometimes firm belief in the reality of dreams, he comes to the conclusion
that our senses are prone to error and thereby cannot reliably distinguish between
certainty and falsity. To examine those ideas that have “objective reality,"
Descartes makes the improbable hypothesis of “an evil genius, as clever and deceitful
as he is powerful, who has directed his entire effort to misleading me” ( ). By
proposing this solution he is able to suspend his judgment and maintain that all his
former beliefs are false. By using doubt as his tool, Descartes is now ready to build his
following proofs with certainty.Meditation Two
Comparing his task to that of Archimedes, Descartes embarks on his journey of truth.
Attempting to affirm the idea that God must exist as a fabricator for his ideas, he
stumbles on his first validity: the notion that he (Descartes) exists. He ascertains that
if he can both persuade himself of something, and likewise be deceived of something, then
surely he must exist. This self validating statement is known as the Cogito Argument.
Simply put it implies whatever thinks exists. Having established this, Descartes asks
himself: What is this I which “necessarily exists”? Descartes now begins to
explore his inner consciousness to find the essence of his being. He disputes that he is a
“rational animal” for this idea is difficult to understand. He scrutinizes
whether perhaps he is a body infused with a soul but this idea is dismissed since he
cannot be certain of concepts that are of the material world. Eventually he focuses on the
act of thinking and from this he posits: “I am a thing that thinks.”(20 ) A
thing that doubts, understands, affirms, denies, wills, refuses, and that also imagines
and senses. To prove that perception on the part of the mind is more real than that of the
senses Descartes asks us to consider a piece of wax. Fresh from the comb the qualities we
attribute to the wax are those derived from the senses. Melted, the qualities that we
attribute to the wax are altered and can only be known to the intellect. Descartes
demonstrates how the information from the senses gives us only the observable, it is the
mind that allows us to understand. The results of the second meditation are considerable,
doubt has both proven the certainty of Descartes existence and that his essence is the
mind.Meditation Three
Descartes main objective in the third meditation is to prove the existence of God. Before
he can begin he must first explore his concept of ideas. Moreover, he must clarify what
constitutes an idea as being clear and distinct. Using his existence as an example he
reasons that whatever he perceives very clearly and very distinctly is true. Concerning
the beliefs he holds of the sensible world, he comes to the conclusion that these things
could have been caused by things outside himself, and the ideas are similar to those
things. Up to this point Descartes has held that God could deceive him about the truth of
simple matters, such as that 2 + 3=5. To affirm that such objective ideas are safe from
doubt, Descartes has to prove that God exists and that he is no deceiver. He finds that
doubt carries within it the idea of certainty. From this query he follows with the idea of
a perfect being, which by comparison, he is aware of his imperfections. It is Descartes
view that such an idea could only have been placed in our minds by a perfect being. His
reasoning for this is as follows: “At the very least there must be as much in the
total efficient cause as there is in the effect of the same cause.”() From this
declaration he ascertains that a perfect thing exists and by definition the perfect thing
is God. He also concludes that God is no deceiver: “for it is manifest by the light
of nature that all fraud and deception depend on some defect.” Content with his
claims Descartes is now ready to move ahead with his argument concerning true and false.Meditation Four
Descartes having proven that God exists must now make some clarifications concerning why
God is no deceiver. The main question that needs clarification is this: If God is no
deceiver then why do we err? Descartes answers that we are prone to make mistakes because
our wills are infinite but our intellect is not. The will gives us the faculties of
assertion, denial and suspension of judgment. The intellect allows us to perceive things
clearly and distinctly. Like God we have an infinite will, but we are imperfect because
are understanding is finite. Descartes concludes that because we are free we are
responsible for our errors. It is possible however, that if we use our faculties properly
we will not assent false judgments. Confident that God has created us such that if we
perceive things clearly and distinctly our reasoning will not be wrong; Descartes is now
free to explore the possibilities of material things and the mind body relationship.Meditation Five
In the fifth meditation the essence of material things is considered. Before he begins
with material considerations however, Descartes feels it necessary to offer another proof
for the existence of God. Since Descartes has just demonstrated that we gain understanding
through ideas, he is able to continue with an ontological argument proving that God
necessarily exists. The claim that is the glue to this argument is that a supremely
perfect being must necessarily exist. If this is not the case the being in question does
not meet the criterion for perfection. God without existence is like a triangle without 3
sides or a mountain without a valley. (paraphrase) A supremely perfect being would lack
some perfection. That taken care of, he turns his attention to material issues, namely the
body. First Descartes separates sensation as being separate from his imagination because
he does not have any control over it. Doubt takes over at this point and Descartes must
again face the same problem he did in meditation one: the unreliability of the senses due
to dreams or hallucinations. To counter this Descartes concludes that our knowledge of
material things is based on our knowledge of God. He asserts that God has created him with
such a strong belief in the existence of material things that they must not be false
because God is not deceptive. By using God as his proof for the material world, Descartes
has left himself in a precarious situation. Were it to be found that God does not exist
the rest of his assertions would subsequently crumble. Nevertheless, Descartes is
satisfied with the progress that he has made and is now ready to prove the existence of
material things.Meditation Six
There remains but one question as we draw near the end of the meditations, whether
material things exist. To prove the existence of the material objects Descartes draws on
his previous meditations to find the answer. He believes that material things can exist,
if they are the object of mathematics. We can prove the existence of these objects because
we can understand them with our intellect. There remains a question regarding our
imagination. Descarte reasons that it is not essential. The understanding is greater than
the imagination. Descartes assumes to have a body based on what his senses perceive. He
begins to explore this notion that he had previously dismissed to doubt. He inquires
whether his senses give him reason for bodies to exist. He comes to the conclusion that
they do because God has given us “a great inclination to believe that these ideas
proceeded from corporeal things.” ( ) This proof progresses into the nature of how
mind and body co-exist. Descartes beliefs are as follows: It is from nature that we
distinguish other bodies and their interpretation. We are inclined by nature towards
things that benefit us. This is for our own self- preservation. Descartes makes the
distinction between mind and body. He states that the mind is a thinking, unextended
thing, while the body is a physical extended thing. The mind is indivisible whereas the
body can be divided. It is the minds task to differentiate the part of the body affiliated
with a certain sensation. God has endowed us with these natural inclinations to allow us
self preservation.
Descartes now dispels his dream hypothesis because he realizes that wakefulness is the
interaction of both mind and body. He leaves us with the message that “we must
acknowledge the infirmity of our nature.” ( )
Explication
It is Descartes hope in Meditation two that he is able to find his first certainty. By use
of the Cogito argument Descartes does just that. Having proven his existance he turns his
attention toward the essence of his nature. As the title of the second meditation
suggests, he proves that are essence is of the mind and thus more known to us than the
body.The Cogito argument as it looks in the Meditations runs like this:
"Thus, after everything has been most carefully weighed, it must finally be
established that this pronouncement "I am, I exist" is necessarily true every
time I utter it or conceive it in my mind." (P.18)
Descartes Second Meditation is an attempt to find a truth that he can accept with
certainty. In order to accomplish this, Descartes has established that his postulate must
be open to strict scrutiny as to expel all doubt to its validity. By the third paragraph
of the meditation he has discovered such a certainty, the claim that “I think,
therefore I exist.” What he is trying to say with this statement is that every time
he thinks something in his mind, he has proof that he exists. It is not possible to think
without also existing. This proof, known as the Cogito, is Descartes first progression
towards his goal of perfect knowledge. For this reason it is important that we examine
this proof so that we can have a better understanding of its meaning.To evaluate the Cogito argument, we must first understand it clearly. There are four key
statements in meditation two that lead Descartes to the certainty that he exists. Herewith
is a summation of Descartes’ argument:
1) “Am I so tied to the body and to the senses that I cannot exist without
them?”
2) “But certainly I should exist, if I were to persuade myself of something.”
3) “Then there is no doubt that I exist, if he (evil demon) deceives me.
4) “I am, I exist” or in other words “I think, therefore I am.”
These claims respectively suggest, that by denying, persuading, and being deceived; a
certain faculty of thought is being used. By thinking, one can be certain that he exists.
Though the argument may seem simple and straightforward, upon closer inspection this is
not the case. There seems to be some questions concerning the Cogito’s
interpretation, the most important being: What is the first certainty that Descartes
uncovers? What perspective does he use to rationalize this certainty?, and how does he
back it up? By examining the inferential, intuitional and epistemic interpretations, we
can discover which interpretation of the Cogito was meant by Descartes in Meditation two.At first it seems obvious that Descartes had meant for the Cogito to be an inferential
argument. Of the key propositions in the Meditations all seem to have the commonality of
thinking as their first premise. Similarly the second premise and the conclusion seem to
follow the same pattern. The second premise posits the notion: Whatever thinks exists;
followed by the conclusion: therefore, I exist.
To know something by inference, is to discover something based on previous knowledge. In
Descartes case, he has come to know a metaphysical certainty, existence, based on a prior
metaphysical certainty, thinking. The soundness of this reasoning is good because know
matter what we do it is impossible to deny that we think. It seems simple enough, until we
consider that Descartes seems to emphasize that his first absolute certainty is existence.
Using the criteria for inference then, it is impossible that “I exist” is the
first certainty. This is a weak argument for in order for this inference to work;
Descartes would have to make revisions to meditation two. However, since he feels so
strongly of this first certainty, I am not convinced that Descartes had meant for this
interpretation.The intuitional interpretation of the Cogito, maintains that it is metaphysically certain
because Descartes has intuited it. Descartes idea of intuition is likened to a flash of
insight. It can be seen to be true, the same way we know that that 2+3=5. He simply knows
he exists based on a direct understanding. With this interpretation, cleary the
proposition “I exist” is the first certainty. The problem of this argument is
that the idea of intuition is too subjective an interpretation to prove that he exists.
There is no way to replicate this procedure and obtain the same conclusion as Descartes.
The evidence for this interpretation is not strong enough to render it to be the one
Descartes intended.The evidence for the epistemic interpretation of the Cogito is good. I feel that this is
the most reasonable interpretation because it seems to be in character with the whole of
the meditations. Descartes reasoning behind his metaphysical certainty is that he simply
has no reason to doubt it. Previous to the second meditation, Descartes had used doubt as
his tool; in doing so he felt it necessary to suspend all judgment. Here he is able to
scrutinize all the major arguments of meditation two and come to the conclusion that he
has no reason to doubt that “I exist.” It could be conceded that Descartes did
not explore enough sources of doubt. This objection seems inconsequential considering the
scope of the problems from the other interpretations.
Having established his existence, Descartes finds that his essence is the mind. He places
a major importance on the intellect. In further meditations it is the mind, through
understanding, that leads us to various conclusions. Near the end of Meditation two,
Descartes demonstrates how the ideas of the mind are more attune to finding knowledge than
are senses are. The point that he makes here is that only through the mind can we
understand the essential qualities of the wax. Melted a piece of wax exhibits qualities
such as extension and mutability. These are concepts that are only clear to the intellect.
The main point that Descartes was trying to get across by using this wax experiment is,
that if he can understand the wax better with his mind, then it certainly follows that he
should know himself better through the same faculty.The Meditations has given me a better understanding of philosophical issues. I have
learned to suspend judgment so that I may use my intellect to understand things. Descartes
presentation of the mind body problem has given me a new topic to explore. Is it the mind
that rules the body or the body that rules the mind. Where does one begin, and the other
end? By using some of Descartes methods I have attempted to see his arguments, and tried
to come to my own conclusions. The mere fact that Descartes found so many certainties in
the Meditations is surprising. It is not always easy to find a hypothesis that stands up
to doubt. The Meditations have taught me to be open minded, and to acknowledge that
sometimes we make mistakes. However, if we take caution and use reason carefully we are
capable of finding certainty.
