Descartes And Berkeley 's Philosophy

In Descartes’ First Meditation, Descartes’ overall intention is to present the idea that our perceptions and sensations are flawed and should not be trusted entirely. His purpose is to create the greatest possible doubt of our senses. To convey this thought, Descartes has three main arguments in the First Meditation: The dream argument, the deceiving God argument, and the evil demon “or evil genius”. Descartes’ dream argument argues that there is no definite transition from a dream to reality, and since dreams are so close to reality, one can never really determine whether they are dreaming

Descartes’ Dreaming Argument comes from his thinking that there is no way of knowing if you are sleeping or if you are awake. To know something is to have no doubt of a fact, it must be a justified true belief. To be justified it must hold logical reason, you cannot state something is true without evidence. In order for it to be true it is not enough to justify it, but it must be justified with true facts. Finally, you must believe it, in order to know something it must be true in your mind. As a result Descartes doubts his consciousness as he cannot truly know that he is awake. This spurs Descartes to question if any perceived knowledge of reality is really true. Descartes calls his senses into questions as he notes, “it is prudent never to trust completely those who have deceived us even once” and therefore concludes that as a result it is prudent, never to trust his sense. In

Rationalism is the theory that opinions and actions should be based on reason and knowledge rather than religious belief or emotional, while empiricism is the theory that knowledge is derived from senses-experience which stimulated the rise of experimental science. The philosophers Descartes, Spinoza, Leibniz, Locke, Berkeley, and Hume all have different views on the existence and nature of external objects. Some see it as the view on objects as everything is sense related other see it that it is all from thought but the object is not existent.

Descartes philosophical meditations offer a window into his beliefs on God and his perceptions. He begins his first meditation by describing his Madness and Dream arguments, which outline his doubts in his own perceptions. He wants to be acutely aware of deception as he moves forward because he has no way of determining when his perceptions are true and when his perceptions are false. Moving through his other meditations, he discusses the idea of truth, goodness, and the existence of God, ending his sixth meditation with the acknowledgement that God would not deceive him, so he must not worry about his perceptions being true anymore. From there, Descartes is not deeply concerned about the truth of his perception of the world. However, upon

Descartes aim throughout the first segment of his Meditations to overthrow existing foundations of knowledge and encourages readers to remove prior knowledge and prejudices in order to fully accept the new foundations which he aims to establish. The method of doubt is used to find beliefs that can serve as a new foundation for knowledge. Only beliefs that are certain, immune from doubt, can perform this function. Descartes argued that what we believe on the basis of the senses cannot meet the standard. Consequently, he concluded, we do not know anything on the basis of our senses and the dream argument is formed.

Descartes believes that knowledge comes from within the mind, a single indisputable fact to build on that can be gained through individual reflection. While seeking true knowledge, Descartes writes his Six Meditations. In these meditations, Descartes tries to develop a strong foundation, which all knowledge can be built upon. In the First Meditation, Descartes begins developing this foundation through the method of doubt. He casts doubt upon all his previous beliefs, including "matters which are not entirely certain and indubitable [and] those which appear to be manifestly false." (Descartes, p.75, par.3) Once Descartes clears away all beliefs that can be called into doubt, he can then build a strong

There are conflicting views between philosophers of the modern era pertaining to the existence of God. Even further, many of these philosophers who share the opinion that God does in fact exist also have opposing views as to how that affects their world view. For example, Descartes’s narrator, in the fifth meditation comes to the conclusion, that God, an almighty benevolent being, is no deceiver, and holds all perfection. Within this system, the narrator attributes all things of the physical world to be material, although Descartes believes that some things are not of matter (i.e. soul or mind). Conversely, Berkeley, whom also is a believer of God’s existence, believes that there is no material world or sensible realm without mind. That through God, the sensible is excited within us and although he, like Descartes ' narrator, does not believe the Author of Our Creation deceives us. Thus even without matter, the regularities of our lives are no accident and have purpose. It is through analyzation of these two texts that I intend to find correlations and differences between Descartes ' and Berkeley 's epistemology in order to ascertain the difference in their world views of dualism (Descartes) and immaterialism (Berkeley), particularly pertaining to their belief in God.

Descartes is able to examine ideas and gain knowledge form them. Innate ideas mean they are present at birth, in other words we are implanted with certain ideas at our creation. He often uses ‘innate ideas’ to explain the mind’s original programming. “An infant’s mind is programmed with the rules of logic. Consider as an example the valid rule, modus ponens. Let P and Q stand for variables… the rules states that, if P then Q is true and P is true, then it follows that Q is true. We know that we are programmed with this rule because young children, who have never studied logic and have never entertained the rule, when given an argument in which the variables above are replaced by actual sentences, are able to intuit the validity of the argument.” Descartes believed our minds are programmed with eternal truths, “Whatever comes into existence must have been brought into existence by something else.” He also discovers that the idea of God is only part of his initial programming but also that God, operating through secondary sources such as his parents, is the programmer.

However, the Meditator realizes that he is often convinced when he is dreaming that he is sensing real objects. He feels certain that he is awake and sitting by the fire, but reflects that often he has dreamed this very sort of thing and been thoroughly convinced by it. On further reflection, he realizes that even simple things can be doubted. Omnipotent God could make even our conception of mathematics false. One might argue that God is supremely good and would not lead Descartes to believe falsely all these things. He supposes that not God, but some "evil demon" has committed itself to deceiving him so that everything he thinks he knows is false. By doubting everything, he can at least be sure not to be misled into falsehood by this demon.

In the First Meditation, Descartes invites us to think skeptically. He entices us with familiar occasions of error, such as how the size of a distant tower can be mistaken. Next, an even more profound reflection on how dreams and reality are indistinguishable provides suitable justification to abandon all that he previously perceived as being truth. (18, 19) By discarding all familiarity and assumptions, Descartes hopes to eliminate all possible errors in locating new foundations of knowledge. An inescapable consequence of doubting senses and prior beliefs

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).

Descartes as a rationalist believes that knowledge comes from the mind alone. During the First Meditation, Descartes came to the conclusion that there must be some kind of evil deceiver that "leads him to a state of doubt" (Descartes 77). Descartes starts out with the fact that distant sensations are subject to doubt and uncertainty. He then goes on to try and cast doubt onto close sensations. Descartes starts off by stating that close sense perception must be certain because we are not crazy, and only a insane person would doubt what was right in front of them. Descartes then uses the dream argument to cast uncertainty on close sense perception because "they are as lively, vivid and clear as reality is when we are awake" (Descartes 76). Descartes then states that geometry and math are certain. "For whether I am awake or sleeping, two and three added together always make five, and a square never has more than four sides; and it does not seem possible that truths so apparent can be suspected of any falsity or uncertainty" (Descartes 98). Descartes comes to realize this certainty because math, geometry, and the simple sciences can be understood and proved through logic and reasoning. He then uses his Deceiver Argument to cast doubt on close sensations. He questions how we know for certain that God is good, and how we know that

He finds it plausible that we are all living in a dream and we have never experienced reality. He can no longer give any credence to his senses and finds himself in a place of complete uncertainty. Descartes comes to the conclusion that nothing can be perceived more easily and more evidently than his own mind. He has discovered that even bodies are not accurately perceived by the senses or the faculty of imagination, and are only accurately being perceived by the intellect. He also realizes that they are not distinguished through being touched, smelled, or tasted, but by being understood alone. (An apple is an apple because our mind tells us that it is an apple.) It is the faculty of reason that gives the knowledge and lets the mind know the truths and essences of objects. Descartes assumes that all of us can be decided by our senses, someone can see something far away, and then discover that is not what we thought it was. Or even a oar when is immerse half in water attempt to be bent, but instead is straight. Descartes think that we cannot always be sure of what we sense, and gives the example of himself seated by the fire.

Descartes believes that knowledge comes from within the mind. This is a single indisputable fact to build on that can be gained through individual reflection. While seeking true knowledge, Descartes writes his Six Meditations. In these meditations, Descartes tries to develop a strong foundation, which all knowledge can be built upon. In the First Meditation, Descartes begins developing this foundation through the method of doubt. He casts doubt upon all his previous beliefs, including “matters which are not entirely certain and indubitable [and] those which appear to be manifestly false.” (Descartes, p.75, par.3) Once Descartes clears away all beliefs that can be called into doubt, he can then build a strong base for all true

Descartes first submits that it is not necessary to show all beliefs are false to satisfy the knowledge condition. He adds that if in each belief there is doubt that we can conclude that all things that we believe can be considered false knowledge. He seeks to prove this by setting a precondition that we cannot critique all beliefs, just the ones that govern our life or that serve as a broad component of belief. Descartes then provides context to where beliefs come from and states that beliefs are created from senses or through senses. He then states that senses are false because they are deceptive and shouldn’t be trusted which is the first cause of being able to doubt a belief. This idea in my opinion is the argument of Reality vs. Virtually, which is what we encounter through our experiences vs. what we dream about. The question posed is that we doubt our beliefs because we do not know if what we perceive from our senses is true. The example provided in the Meditations text dealt with imagination and the Dream world concept. If I perceive something in the
