Rene Descartes

how can we be shure of our existence? Well descartes the father of the modern philosophy asked him selve the same question along time ago. According to his thoughts the only way of being shure of our existence is trusting in our minds that reason but not in our sences because most of the times they fail us, he was tha one that said the frase ' I think therefor I exist '. This frase has has causes a lot of controversy with many other philosophers like Francis Bacon that was against the rationalism and in favor of the empiricism.
Rene Descartes is now one of the most famous philosophers because of his theory or thought about rationalism. One of his thougts is that everything in the world is mechanicaly and mathematicaly understandable, one example of this is the 'plano carteciano', throught this method we can mathematicaly say were things are.
There is another thougth of Descartes that tell us that the world is diveded in two parts the once that material and the others that are the substances, according to him substances are an extencion of god and and the material things that are the once that work mechanicaly.
In conclusion my point of veiw Descartes is that he was a brilliant person and I agree with him on his point of view of sences, any time they can fail us.
