PHILOSOPHICAL IMPLICATION OF DECARTES METHOD
PHILOSOPHICAL IMPLICATION OF
DECARTES METHOD
The cogito ergo sum, “I
think, therefore I exist” is at the heart of Rene Descartes philosophy in the
Cartesian method. As mentioned above, Descartes sought out to doubt everything
he had ever known. But why did he had to doubt? He felt and rightly observed
that there could be deception of the senses, deception by a demon and of course
deception that comes about from a state of dream. In this setting, true and
certain knowledge was impossible, thus, he was led to a form of scepticism. But
it dawned on him that while he was doubting everything, he was also thinking.
He further observed that doubting is a function of thought, of the thinking
faculty. But he wondered how one can think if one does not first exist. He
therefore came to the conclusion that, doubt concerning his own existence was
impossible because he needed to exist before he could even think and he needed
to have the ability to think before he could doubt, consequently, that he
thinks shows that he exists. Thus the only absolute certainty he was sure of,
and on which he built his philosophy, was the cogito ergo sum, “I think, therefore, I am.” Every time Descartes
asserts, ‘I am thinking,’ he must assert the “I” thus asserting the existence
of the self who in doing the thinking.[1]
Furthermore, the cogito became instrumental
to prove his existence, that of other material things, and that of God.
Descartes considered the cogito to be a “purely intellectual” truth, that is,
one which is entirely conceptual, and a
priori.[2]
The implications of this Descartes method, will be if he says I
think therefore I am that will mean on the surface level that Rene Descartes is
nothing but a thinking being, and what is the thinking faculty is the mind
which means the Descartes is nothing more than his mind. So the I in "I
AM" is not the Descartes you see but the faculty of thinking, which makes
Descartes reduced a human person to the mind which is the thinking being not a
knowing being.
More so, another implication will be that knowledge for Decartes
comes from the intellect but not from the senses because senses experience
never puts us in contact with object itself but only mental images, senses
perception provides no certainty that there is anything in the external world
that corresponds to the image we have in our mind. Thus can we truly know the
independence of the sense.
Furthermore, Ethically one cannot be held responsible for his
action, because human person can claim not been responsible for the action but
the Mind. If you reduce a person to the mind the person can't be held responsible
when the senses is in act.
Moreover, another implication will be that of body mind problem
(dualism). If the person is in the mind and the mind is contain in the body,
how will the body and the mind interact?
Finally for him saying he is dismissing all his knowledge, there is
something he is not dismissing which is the fact of certitude that he is
dismising everything.
