Des Cartes's idea of knowledge

In class we talked about Des Cartes's beliefs and theories. One of Des Cartes's points was that knowledge is accesable to everyone in the same way and that man has the capacity to come up with truth. This is a major point I'm going to make in my paper so I won't elaborate on it to much in this blog but I disagree with Des Cartes's theory. I don't think everyone can comprehend knowledge in the same way. Not everyone can reach to the same level of knowledge as others can. I don't think I could ever reach the level of knowledge as Albert Einstein could no matter how hard and how long I tried - its just not possible. I also disagree with the idea that we have the capacity to come up with truth. Although humans have the capacity to comprehend obvious truths like 2+2=4 and my mother is female. Man will never come up with an answer such as "Is their a God" and "How Earth was created" - Man can come up with a truth they believe in such as christianity or the big bang theory but this is not truth because it cannot be proven. This is only a small basis of what I will cover in my paper
