Abstract
Rene Descartes' method of doubt provides a powerful tool for attempting to determine the fundamental nature of reality. The paper analyzes Meditations I and II, where Descartes uses the Method of Doubt in order to attempt to determine which beliefs and opinions are true. It shows that in order to do this, Descartes proposes a series of skeptical hypotheses, each aimed at determining if we can trust our specific faculties of sense, reason, and imagination. The paper concludes that Descartes method of doubt determines that all that we can truly know is cogito ergo sum (I think, therefore I am).

From the Paper
"Descartes notes that examining each belief, and determining if it is true "would be truly an endless labor". As such, he argues that it is necessary to attempt to find a principle that can serve as the fundamental basis, or bedrock, for all his beliefs. Descartes argues that examining each individual belief is unnecessary, as well as laborious, given that an examination of his fundamental belief will reveal if all other beliefs, which rest upon it, are true as well. Says Descartes, "as the removal from below of the foundation necessarily involves the downfall of the whole edifice, I will at once approach the criticism of the principles on which all my former beliefs rested" Descartes, Meditations I)."

Abstract
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."

Abstract
This paper provides a general biography of Rene Descartes, as well as a basic summary of his philosophical tenets. The paper also discusses Descartes' accomplishments in the field of mathematics as well as philosophy.

From the Paper
"Often considered the father of modern philosophy, Renee Descartes is one of the most influential ground-breaking thinkers in the history of human thought. Indeed his accomplishments go beyond the field of philosophy as he was an elite mathematician who is credited with inventing analytic geometry. However it is Descartes' work in laying the philosophic foundation for modern scientific thought that is his greatest achievement. Descartes' philosophy was deeply rooted in rationalism because he began his inquiry by questioning the very validity of the knowledge that man believes he possesses."

Abstract
This paper is an exposition of Descartes' "Meditations". It concentrates on the central argument that material objects have existence separate from the perceptions that they give rise to. The paper also explains what systematic doubt is and why Descartes makes this his starting point. The paper also examines how, having spelt out the philosophical problem in the first "Meditation", Descartes aims to solve the problem through the subsequent five Meditations, thereby arriving at certainty regarding material existence. The paper follows the steps of the argument without critical analysis of it.

From the Paper
"Doubt is part of everyday existence; for example we doubt whether we will pass an exam. This is real doubt, but it is not the sense in which Descartes doubts. He engages in metaphysical doubt, which means that he doubts things that we would not normally doubt, for example that a piece of ice would feel cold when we touched it. Through experience we have leant to trust our senses, and the mere sight of ice leads us to believe that it will feel cold. But it could be the case that we picked up a marble slab thinking it a piece of ice, and then it would not feel as cold. So the senses can deceive us, and we have cause to doubt. But if all our knowledge comes through the senses, there are grounds for us to doubt everything. Through systematic doubt Descartes wants to arrive at the worst case scenario, to come to all that it is possible to doubt. "

Abstract
In attempting to connect philosophy and theology, Rene Descartes made certain novel assumptions that, at the outset, would appear to contradict themselves. He believed that only the physical world could be proved according to mathematical evidence, yet, stated that the very existence or presence of an idea of a perfect God in the mind already suggests His reality and existence. The paper discusses Descartes's views that, in the act of perceiving reality, the human soul goes through activities, such as understanding, conceiving, doubting, affirming, denying, willing, refusing, imagining, feeling, and desiring. These activities share the common quality of deliberate thought or perception. The paper explains Descartes's idea that thought, then, is the essential attribute of the soul.

"It is however, disastrous to accept Descartes? concept of passions as animal spirits circulated by the blood and originating from our pineal gland. If they were inherently physiological, then we need not worry about being responsible for our deliberate acts. There will cease to be any difference between what is right and what is wrong. Civilization will collapse and life itself will vanish from the planet. We should not blame the bleakness or dignity of human existence to the pineal gland."

Abstract
This paper discusses the Cartesian mind-body dilemma by analyzing Descartes' "Meditations on First Philosophy". The paper explains that Cartesian dualism intended to moderate between the established religious paradigm of the time and the emerging natural sciences and by positing mind and body as complete substances which refer to nothing but themselves. The paper also looks at how Descartes' theory of mind preserves the religious conception of man as an immortal soul in possession of free will by placing such outside the realm of the physical sciences. The paper points out that Descartes' "Meditations on First Philosophy" seeks to establish two distinct classes of substances in mind and extension, but fails to adequately address the manner in which these two incommensurable substances interact to generate our experience of the world. The writer suggests that Descartes conceives of the body as a 'kingdom within a kingdom' of mind, and is left with the problem of how these kingdoms are able to carry out diplomatic relations with one another.

From the Paper
"The cogito, 'I think therefore I am', delimits mind as the substance of thought, the primary existential of being. This is arrived at by proposing that there could be a malicious demon of some sort that may be propagating a vast illusion of experience, generating even our thoughts. Even in this radical scepticism, however, Descartes concludes that there must be something that this hoax is played upon, and no matter what this demon may be able to do, he can never convince something that it is nothing; "...I must finally conclude that this proposition, I am, I exist, is necessarily true whenever it is put forward by me or conceived in my mind" . The cogito, therefore, shows mind to be a substance that is necessarily true without reference to any other substance. It is the essence to which all the modes of thought refer."
