Three problems with Descartes I think therefore I am theory
Problem Number 3
Perfection can only come from perfection.
This is problematic for a number of reasons.
Firstly Scottish Philosopher David Hume finds this statement
That perfection can only come from perfection
Very odd indeed.
This is because he claims that you can arrive at the idea of God
By magnifying ones own qualities
For example it would be strange to think
That you can not have the concept of a very strong man
If you yourself are not strong
Because all you would have to do to think of someone
That is stronger than you
David Hume states that the same applies for God
All one has to do
Is look at certain qualities in himself
Such as goodness wisdom and strength
And then think of something with those qualities magnified to a great extent.
Secondly Descartes is also critiqued
Because he had not yet proven that the belief
Perfection can only come from perfection is without doubt
It could could be the case
That the evil demon has just deceived Descartes
Into thinking that God is the source of his concept of a perfect being
When really he was the one who gave it to Descartes
Sorry Descartes but it looks like the demon has caught you out on this one.
Problem number 2
The mind exists separate to the body
One major problem with this claim
Is that there is a great deal of evidence
To suggest that our thoughts are easily affected by things
Such as brain damage
Caused by the results of drugs accidents and disease
Scientists even went as far to prove this point
As to damage certain parts of monkeys brains
In order to see what changes are made to their way of thinking
Unfortunately the monkeys did not rise up and start a monkey revolution
Like in Rise of the planet of the Apes
But instead experienced massive changes in behaviour
Caused by brain damage
Despite all this
The point is that there is clear evidence to show
That our thoughts and the body are much more closely linked
Than Descartes first suggested.
Problem number 1
I am think, therefore I am
This is one of most critiqued claims of Descartes Theory
The most famous criticism against this claim
Is raised by the Philosopher
Pierre Gassendi
And is later expanded on by mustachio
Fredrich Nietzsche
Who states that Descartes is wrong to say that
I am thinking since he has not proven that it is him that is thinking.
Since it could instead be the case that the thoughts he is having
Are coming from somewhere else
A more appropriate thing to say would be
There are thoughts
This however would not allow Descartes to go and expand to say that
I exist
Which ultimately means
He can not go on to prove that his beliefs
Are without doubt.
Meaning that the only thing we can be truly certain of is that
There are thoughts
