     On the journey to find truth to base all thought upon, Descartes explains his first step in doing so. “Never accept anything for true which I did not clearly know to be such; that is to say, carefully to avoid precipitancy and prejudice, and to comprise nothing more in my judgment than what was presented to my mind so clearly and distinctly as to exclude all ground of doubt.”(Kolak, Pg.228). Assuming that everything you see is fictitious, Descartes believed he had no senses at all; “body, shape, extension, motion, and place are unreal.”(Weissman, Pg.23). Our senses have failed us all at one point or another in our lives, so why use the senses as a base for thought? The most famous quote and philosophy by Descartes in history ever, “Je pense, donc je suis, cogito ergo sum” (Durant, Pg.639). “I think, therefore I am” was the first step towards a basis to understand truth, and leaning away from truth through the senses.

‘Cogito Ergo Sum,’ - ‘I think therefore I am ‘ one of the most famous and well known quotes or arguments in all of modern philosophy; a phrase instantly recognizable to all those studying in the field of philosophy. This phrase refers to an attempt by Descartes to prove with absolute certainty his own existence; a systematic way to philosophize. The argument, while first proposed by ancient philosophers such as Aristotle and Saint Augustine, was utilized as an argument by French philosopher Rene Descartes in his influential text “Meditations on First Philosophy“. This argument appears in the books second meditation and provides the cornerstone for Descartes argument in the following five meditations and serves as the basis for Descartes overall metaphysical thesis, without which Descartes reasoning system would collapse. Throughout this paper I will

In the book Discourses on the Method and the Meditations, author Rene Descartes famously questions the existence of humanity. His most famous quotation, the one for whom he is most remembered is "I think therefore I am" (Descartes 11). According to this idea, so long as a being has the ability to think then they existed. Animals have brains and therefore they must exist. In order to truly, exist, to be a thinking entity, a person or organism must utilize the ability granted to them by their mind. This is the focus of much of this text, the nature of existence and the line between what is true and what we only imagine or perceive to be true. For the majority of the text, the philosopher asks questions in trying to formulate his own identity and indeed whether or not he existed as all. It would be assumed that the end of the book would be a conclusion of this internal dialogue where Descartes definitively states his position on human existence. However, Descartes instead devotes the end of the text to a wholly new concept: namely he applies the question of existence to a being above humanity. At the end of the text, instead of continuing on with these questions Descartes instead discusses the idea of God and whether or not He exists.

Something very essential to know about Descartes is his idea of Cogito Ergo Sum; I think, therefore I am. He believes that he exists because he is thinking, making him a thinking thing. Descartes first premise states, "I have a clear and distinct idea of myself, in so far as I am simply a thinking, non-extended thing" (Descartes, 54). The first thing that we need to understand from this premise is what Descartes means by extended; to occupy space. So, since he believes that he is not an extended thing, it follows that he does not take up space. Given this, he looked inside himself and saw no parts within his mind, no space or boundaries that his mind contains. In addition, the mind provides a place for free will and faith, which are not parts but different ways of thinking. He rationalizes this by making the mind of a qualitative substance. By saying that only things that can be measured must be of a material substance and those things that cannot be measured are of a thought like substance. The relation between body and mind now seem to be more divided since he believes that his mind is not extended. In short, this premise states that the mind has no parts, making it indivisible.

In a quote previously shown, Descartes claims that his idea of a perfect being comes from God. Descartes also believes that the idea

Do we considered our senses to give us the real answer as to what is real or can these senses give a false knowing? Descartes in Meditation One and Two questions his knowledge of his own self as to what’s real and is just a matter of opinion. The main question throughout Descartes’ text, in Meditation One, is whether his opinions are all to be considered false in a matter of opinion? He states, “however, I have noticed that the senses are sometimes deceptive; and it is a mark of prudence never to place our complete trust in those who have deceived us even once (Cahn, Location: 18644).”

In the meditations, Descartes evaluates whether or not everything we know is a reality or a dream. Descartes claims that we can only be sure that our beliefs are true when we clearly and distinctively perceive them to be true. As the reader analyzes the third meditation, Descartes has confirmed that some of his beliefs are in fact true. The first is that Descartes himself exists. This is expressed in what has now become a popular quote known as the “Cogito” which says, “I think therefore I am. His second conclusion is that God exist and that he is not a deceiver. Descartes then presents his arguments to prove the existence of God. He argues that by nature humans are imperfect beings. Furthermore, humankind could not possibly be able to comprehend perfection or infinite things on their own. He writes, “By the name of God I understand a substance that is infinite, independent, all-knowing, all powerful, and which myself and everything else…have been created.”(16) Descartes uses this description of God to display the distinction between God and man.

In this paper I will be discussing the things that Descartes “Cogito, ergo sum” as well as things he doubted such as the senses, as well as his evil demon hypothesis (pg322 of The Great Conversation). I will also be challenging his doubt of the senses, and evil demon hypothesis. Descartes “Corgito, ergo sum” is “I think therefore I am” meaning that because he has the ability to think rationally as wells as make decisions and doubt his surrounding/emotions/senses means that he must exist. For example, this quote is as I breath therefore I produce carbon dioxide. He is stating something that he does which in turn proves something else.

For in Descartes terms, it was plausible to doubt that one has a body, but impossible to doubt the existence of one’s mind; therefore “…self and mind must be identical” (Palmer 162).

Since Descartes was able to think, he knew that he existed ultimately. With this in mind, Descartes reckoned that a person 's "self" illustrates their identity. Descartes states: “that he possesses a body intimately conjoined... and that he has a clear and distinct idea of himself, inasmuch...it is certain that this I [that is to say, my soul by which I am what I am], is entirely and absolutely distinct from my body, and can exist without it" (Descartes, Meditations On First Philosophy, pg.29). In fact, Descartes proposes that the body connects dually with the mind, which he believes the body is "divisible", and the mind as "indivisible", but he also informs the readers that he knows certainly who he is. Not only did Descartes deem this information as true, but he was adamant about the possibility of living without a soul. In particular, Descartes depicts a vivid picture of how the

It is from this thought that Descartes is able to determine God exists and create his first

Rene Descartes is a modern French philosopher, who is famous for his line, “I think, therefore I am.” The meaning of this quote is that he must exist because he has the ability to think. In Descartes most famous work, The Meditations, he starts off by doubting everything, which is known as the Method of Doubt. He believes that our senses are always deceiving us in some way and so our senses are unreliable in proving anything. By this, he means that when we use our senses, such as our vision, to look at something, the way that the object looks from afar is different from the way it looks upfront, thus, deceiving us. However, Descartes

René Descartes was a French philosopher and also mathematician. His method of doubt led him to the famous "cogito ergo sum" when translated means "I am thinking, therefore I exist". This cogito was the foundation for Descartes' quest for certain knowledge. He explored doubt and how we can prove our own existence, by taking the first steps of scepticism. His book "Meditations On First Philosophy", was written in six parts. Each representing the six days that God took to create the world. Not to upset the Church, Descartes would need to prove the existence of God, and the soul. Within Descartes' argument, we find some important areas. Two, which require focus, are his

In this paper I intend to show that Descartes’ cogito ergo sum and ontological arguments both rely on the method of doubt and follow from the premise that essence implies existence. The cogito ergo sum is different from the latter one, however, from the fact that it did not contain the premise regarding the cause and effect of an idea having objective reality. The main problem with this argument is that while essence and existence were said to be inseparable, it does not happen to be the case.

During Meditations 2, Descartes establishes a version of his famous ‘cogito ergo sum’. He establishes that despite the fact that we may not know the world around us as well as we think we do, we can know the mind better and the trusting the mind can lead him to the seemingly justified conclusion that he exists.
