For the most part, epistemology is the theory of knowledge. In essence, it is a part of philosophy that deals ,not only with the mere concept of knowledge, but also with the nature, sources, and scope of knowledge. This paper presents an overview of the philosophy of epistemology and then looks specifically at Rene Descartes's Latin phrase. "COGITO ERGO SUM", which translates to "I think, therefore I am".
From the Paper:
"Next, the terms " I am". These words tend to mean the necessary existence of Rene Descartes. "I" being Rene Descartes and "am" being the existence of Descartes. Through this a further analysis is made to the effect that the issue of what is "I am" is personalized by the person stating such words, so that in this case "I am" is Rene Descartes being the existence of Rene Descartes."
