Initial answer: My initial answer is to the question of whether scientific knowledge should be based on observations is yes, observations are to be the basis of all scientific knowledge.
Philosophical context: I shall use Descartes’ Meditations 1 and Blackburn 's “Think” to discuss the question and my initial answer. In Meditations 1, Descartes sets out to destroy all preconceived notions from his childhood and establish a new foundation for the sciences -- a lasting foundation and explores methods of doubt to his own senses and how to deal with them properly.
Objection 1 to my initial answer: In Mediations 1, Descartes states that sometimes senses deceive us, so for all we know is that they always deceive us. This being the case he suggests

As Blackburn says, dreams are not as coherent as everyday life, they are shakier. Similar to this, Descartes says that dreams are like a painting. Objects could look like they are real; made in the fashion of those in the waking world, so therefore they have to be real giving a basis for scientific observations. These corporeal objects give rise to concentrations of science such as astronomy, medicine, physics, that use the observations that could seem doubtful if we are to take the dreaming argument into consideration without allowing for the fact that dreams must be based on waking life, and others, such as mathematics and geometry, are still unquestionable no matter if you try to base the dream off of reality. As Descartes says, “where I am awake or asleep, two and three added together are five.” Taking all of this into consideration, whether or not one is dreaming some science still remains, meaning observations are still viable in scientific knowledge. So my answer that you may use observations with care and thorough study still holds true, because even in a dream state there is still rational mathematics and science based off of reality. Along with these facts, many dream states can be recognizable through their slight disillusionment from everyday life, leading to one to realize they are asleep (lucid dreaming), which is not …show more content…
He claims “cogito, ergo sum,” meaning I think, therefore I am. By saying this Descartes shows that in order to be thinking you must exist and therefore are not the puppet of an Evil Demon. As said by Keith Crome in his essay on the Evil Demon, “as Descartes observes, for all that there is an all-powerful and cunning deceiver dedicated to constantly deceiving he cannot bring it about that I am nothing, because it is indubitable that if I am deceived, I exist.” This just points to the fact that in order to be controlled and realize the fact you must actually have to be real. And to that point if there were to be an evil demon controlling all our actions, why would he allow for the doubt that we are in charge that gives rise to the theory itself? If it was truly in control, wouldn’t we go about life never questioning whether or not we are real? In relation to my initial answer, the evil demon does not change much, because either he is or he isn’t, and there is no certain way to know. All we have for certain is “I think, therefore I am” to prove that we are thinking beings and that is enough to contradict the Evil
At the start of the meditation, Descartes begins by rejecting all his beliefs, so that he would not be deceived by any misconceptions from reaching the truth. Descartes acknowledges himself as, “a thing that thinks: that is, a thing that doubts, affirms, denies, understands a few things, is ignorant of many things” He is certain that that he thinks and exists because his knowledge and ideas are both ‘clear and distinct’. Descartes proposes a general rule, “that whatever one perceives very clearly and very distinctly is true” Descartes discovers, “that he can doubt what he clearly and distinctly perceives is true led to the realization that his first immediate priority should be to remove the doubt” because, “no organized body of knowledge is possible unless the doubt is removed” The best probable way to remove the doubt is prove that God exists, that he is not a deceiver and “will always guarantee that any clear and distinct ideas that enter our minds will be true.” Descartes must remove the threat of an invisible demon that inserts ideas and doubts into our minds to fool us , in order to rely on his ‘clear and distinct’ rule.
Throughout “Mediations I and II”, Descartes disputes definitions of reality and identity, establishing a precursor to Emerson’s philosophy. Initially, Descartes questions all notions of being. In “Mediation I”, Descartes begins his argument explaining the senses which perceive reality can be deceptive and “it is wiser not to trust entirely to any thing by which we have once been deceived” (Descartes 59). But, he then continues to reason; “opinions [are] in some measure doubtful…and at the same time highly probable, so that there is much more reason to believe in than to deny them” (Descartes 62). Descartes maintains trust within his established personal beliefs though he may doubt certain physical senses. Additionally, Descartes seeks to establish his identity in “Meditation II”. Even as he questions his very existence, he begins trustin...
Baird and Kaufmann, the editors of our text, explain in their outline of Descartes' epistemology that the method by which the thinker carried out his philosophical work involved first discovering and being sure of a certainty, and then, from that certainty, reasoning what else it meant one could be sure of. He would admit nothing without being absolutely satisfied on his own (i.e., without being told so by others) that it was incontrovertible truth. This system was unique, according to the editors, in part because Descartes was not afraid to face doubt. Despite the fact that it was precisely doubt of which he was endeavoring to rid himself, he nonetheless allowed it the full reign it deserved and demanded over his intellectual labors. "Although uncertainty and doubt were the enemies," say Baird and Kaufmann (p.16), "Descartes hit upon the idea of using doubt as a tool or as a weapon. . . . He would use doubt as an acid to pour over every 'truth' to see if there was anything that could not be dissolved . . . ." This test, they explain, resulted for Descartes in the conclusion that, if he doubted everything in the world there was to doubt, it was still then certain that he was doubting; further, that in order to doubt, he had to exist. His own existence, therefore, was the first truth he could admit to with certainty, and it became the basis for the remainder of his epistemology.
In the second meditation, Descartes is searching for an Archimedian point on which to seed a pearl of certainty. By doubting everything in his first meditation, Descartes consequently doubts his own existence. It is here that a certainty is unearthed: “If I convinced myself of something then I certainly existed”(17). However, Descartes “does not deduce existence from thought by means of syllogism, but recognizes it as something self-evident by a simple intuition of the mind,” or in other words, by natural light (Second Replies:68).
In Descartes Third Meditation, he establishes arguments to prove the existence of God. Descartes believes in “Cogito Ergo Sum” this means I think therefore I am. The “I” in this sentence means the soul. Descartes believes the existence of the mind is better known than the existence of the body. If my soul thinks then I exist. The Cogito proves the existence of self or the mind; this is not the same for the theory of God. Descartes has two arguments in the Third meditation. The arguments are the cause of his idea of God and the cause of his existence now.
In his work, Meditations on First Philosophy, Descartes narrates the search for certainty in order to recreate all knowledge. He begins with “radical doubt.” He asks a simple question “Is there any one thing of which we can be absolutely certain?” that provides the main question of his analysis. Proceeding forward, he states that the ground of his foundation is the self – evident knowledge of the “thinking thing,” which he himself is.
Rene Descartes’ greatest work, Meditations on First Philosophy, attempts to build the base of knowledge through a skeptical point of view. In the First Meditation, Descartes argues that his knowledge has been built on reason and his senses, yet how does he know that those concepts are not deceiving him? He begins to doubt that his body exists, and compares himself to an insane person. What if he is delusional about his social ranking, or confused about the color of his clothes, or even unaware of the material that his head is made of? This is all because the senses are deceiving, even in our dreams we experience realistic visions and feelings. Finally, Descartes comes to the conclusion that everything must be doubted, and begins to build his
Descartes begins his Second Mediation by stating that in the previous day during his “Project” he had been coming across much doubt “… ones that are too serious to be ignored.” But in results of this he ponders upon many questions like whether or not he himself his “something” and that if he is indeed thinking that he must be something. What is one person that can 't think? But a thing that can indeed think must be existing or else it would not be able to think. Even though he had previously convinced himself that nothing exists not even the Earth, the sky nor himself. But if he is having these thoughts of doubt he is saying that he must exist if he himself is able to think. He later states that there may be an almighty power above him and he may be the one deceiving him. But again he stumbles across the thought that he must exist in order to be deceived. So if there is someone above him that someone cannot deceive nothing. So if that almighty power is deceiving what Descartes believes is him then Descartes, Himself, does undoubtedly
Our mind and our body are undoubtedly separate from each other. A mind can survive without a body, and, likewise, a body is just house for the mind. In The Meditations, Descartes describes this concept in his dualist theory in the second of multiple Meditations. We can reach this conclusion by first understanding that the mind can survive any destruction of the body, and then realizing that you are identical to your mind and not your body. In other words, you are your thoughts and experiences – not your physical body. Finally, you cannot doubt your own existence, because the act of doubting is, itself, and act of thinking, and to think is to exist as a “thinking thing,” or Res Cogitans.
Descartes’ first two Meditations are arguably the most widely known philosophical works. Because of this, one can make the error of assuming that Descartes’ method of doubt is self-evident and that its philosophical implications are relatively minor. However, to assume this would be a grave mistake. In this paper, I hope to spread light on exactly what Descartes’ method of doubt is, and how, though it furnishes challenges for the acceptance of the reality of the external world, it nonetheless does not lead to external world skepticism.
Rene Descartes decision to shatter the molds of traditional thinking is still talked about today. He is regarded as an influential abstract thinker; and some of his main ideas are still talked about by philosophers all over the world. While he wrote the "Meditations", he secluded himself from the outside world for a length of time, basically tore up his conventional thinking; and tried to come to some conclusion as to what was actually true and existing. In order to show that the sciences rest on firm foundations and that these foundations lay in the mind and not the senses, Descartes must begin by bringing into doubt all the beliefs that come to him by the senses. This is done in the first of six different steps that he named "Meditations" because of the state of mind he was in while he was contemplating all these different ideas. His six meditations are "One:Concerning those things that can be called into doubt", "Two:Concerning the Nature of the Human mind: that it is better known than the Body", "Three: Concerning God, that he exists", "Four: Concerning the True and the False", "Five: Concerning the Essence of Material things, and again concerning God, that he exists" and finally "Six: Concerning the Existence of Material things, and the real distinction between Mind and Body". Although all of these meditations are relevant and necessary to understand the complete work as a whole, the focus of this paper will be the first meditation.
The teaching of Descartes has influenced many minds since his writings. Descartes' belief that clear and distinct perceptions come from the intellect and not the senses was critical to his ultimate goal in Meditations on First Philosophy, for now he has successfully created a foundation of true and certain facts on which to base a sold, scientific belief structure. He has proven himself to exist in some form, to think and therefore feel, and explains how he knows objects or concepts to be real.
Within meditation one Descartes subjects all of his beliefs regarding sensory data and even existence to the strongest and most hyperbolic of doubts. He invokes the notion of the all powerful, malign demon who could be deceiving him regarding sensory experience and even his understanding of the simplest mathematical and logical truths in order to attain an indubitable premise that is epistemologically formidable. In meditation one Descartes has three areas of doubt, doubt of his own existence, doubt of the existence of God, and doubt of the existence of the external world. Descartes’ knowledge of these three areas are subjected to three types of scepticism the first where he believes that his senses are being deceived ‘these senses played me false, and it is prudent never to trust entirely those who have once deceived us’. The second of the forms of scepticism revolves around whether Descartes is dreaming or not ‘I see so clearly that there are no conclusive signs by means of which one can distinguish between being awake and being asleep’. The aforementioned malign demon was Descartes third method of doubt as he realised God would not deceive him.
In Meditations, Descartes brings doubt to everything he believes because it is human nature to believe that which is false. He states that most of what he believes comes from the senses and that a lot of times those senses can be deceived. His conclusion of doubting everything is based on his example of a basket of apples. It goes as follows; you have a basket of apples but you fear that some apples have gone bad and you don't want them to rot the others, so you throw all the apples out of the basket. Now that the basket is empty you examine each apple carefully and return the good apples to the basket. This is what he does with his beliefs, he follows and keeps only those beliefs of which he is sure of. Our beliefs as a whole must be discarded and then each individual belief must be looked at carefully before we can accept it. We must only accept those beliefs we feel are good.
In conclusion, the initiation in philosophy of methodological scepticism will constitute, after Descartes, becoming the obsessive theme of reflection of modern philosophy. Descartes’ mediations are the ones which expose the results of metaphysics based on principles. For the building of this philosophy those principles must be absolute certain. Descartes realises this and doubts all his previous knowledge, not to reach a sceptical conclusion but to find absolute certain elements beyond doubt, allowing him to find the foundation on which he can build the rest of his thinking.
