Modern Understanding Descartes

The Evil Demon Hypothesis is an important component of the Method of Doubt. Descartes used the Method of Doubt to find what is true by withholding assent from all beliefs that are dubitable. However, if Descartes was to scrutinise everything he believed, he would be left with an

This essay will attempt to discuss the strengths and weaknesses of Descartes’ dreaming argument and evil demon argument. Through discussion, I will show why the evil demon argument is more plausible than the dreaming argument. The essay will give a brief definition of the two arguments and explain why these arguments are important. Then I will discuss the two arguments, considering both sides and referencing previous work by other philosophers. I will conclude with a short summary of the topics covered.

Clear your mind, if you will, of everything you have ever seen or known to be true. To begin understanding Rene Descartes’ method of doubt, you need to suspend all prejudice and prior judgments and start with a clean slate “for the purpose of discovering some ultimate truth on which to base all thought.” (Kolak, Pg.225). Discouraged with much skepticism from his own beliefs, Descartes was embarrassed of his own ignorance. He set out to try and accomplish the task of finding an absolute truth in which he would base his beliefs. Placing upon himself a task to find an axiom or absolute truth to base all thought, “he ventured as a youth in travel to collect a variety in experiences to derive some

The cogito, “I think” is Descartes’ first certainty and his first step into knowledge. Descartes argues that there is one thing that he is most certain of and even the evil demon can manipulate and make him doubt. He cannot doubt that he thinks because even doubting of a form of thinking and that means that he will be thinking. Even if the demon made him doubt that he is thinking, he would be confident that he is thinking that the demon is making him doubt his thinking. He cannot also doubt that he exists and if he were to doubt of his existence, he would prove that he exists because of his thoughts, and thus his thinking means he exists and hence if he exists then he must be thinking of his existence. Therefore, Descartes extends his certainty

In his First Meditations, Descartes also forms the evil demon argument. Much like the dreaming argument, the evil demon argument also focuses on doubt and the extent to which we can trust our senses.

Descartes dreaming argument suggests that perhaps our senses cannot be fully trusted because we cannot be certain we are not dreaming, and this means we therefore cannot be certain of anything. His evil demon argument is similar but uses the idea of an evil demon deceiving you instead of your senses. These sceptical arguments mean that we cannot be certain of anything at all for it may be happening whilst we are dreaming, or we are being tricked into thinking it is happening. I do not agree with Descartes because I feel that I can be certain I am not dreaming, and I do not believe that other supernatural creatures; such as an evil demon exists.

Descartes organised his ideas on knowledge and skepticism to establish two main arguments, the dreaming argument and the evil demon argument. The dreaming argument suggests that it is not possible to distinguish between having a waking experience and dreaming an experience. Whereas, the evil demon argument suggests that we are deceived in all areas of our experiences by an evil demon. This essay will investigate the validity of the arguments and to what extent the conclusion of these arguments is true. The soundness and the extent to which the premises are true will also be explored. After evaluating these arguments it will be concluded that the dreaming argument is valid, but is not sound. Whereas, the evil demon argument is both valid and sound.

In the fifth and last skeptical hypothesis, Descartes raises the possibility of there being an evil demon that deceives him into believing falsehoods. Descartes has established arguments that either support or demolish the thoughts for all of these skeptical hypotheses. As stated previously, the dream argument points out that people may actually be dreaming when they think they are living in reality. Descartes used his methods of detecting falsities to evaluate this argument.

‘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

Descartes begins the method of doubt by how he was struck by the large number of falsehoods that he had accepted in his youth that was taken to be true, and how doubtful they were and had subsequently built upon them. Since he knows that many of his beliefs are based on false opinions, he is not sure which of them he can trust and which he can’t. Descartes presents his philosophical project, and claims that he needs to put into questions the truth of all his beliefs. Descartes shows that we can doubt the truth of all our beliefs by two main arguments, the Dream Argument and the Evil Genius argument. I agree with the fact that Descartes suggest there isn’t any objective way to confirm whether we are awake.

Descartes argues the reliability of the senses, the dreaming argument, and the evil demon argument. Dream argument is the method of doubt that rules out trusting one's senses that an external world of physical objects exists, including people. My own body and other people may be dreams so we are not sure. The evil demon hypothesis is the idea that an evil demon has placed memories, causing doubt in your own memories. The method of doubt rules out trusting that our memories are true. It’s important to doubt ideas because it gives a sturdier foundation to knowledge. We get our experiences from our senses that our senses can deceive us. For example when you dream you sense real objects. In the moment you perceive the objects as real but when you wake up you realize you were

René Descartes was the first philosopher to raise the question of how we can claim to know anything about the world with certainty. The idea is not that these doubts are probable, but that their possibility can never be entirely ruled out. If we can never be certain, how can we claim to know anything?

Dream Skepticism has been debated largely since Descartes’ projection of those ideas. Descartes believed many irrational thoughts in relation to dreaming, which proposed ideas that nobody at his time had ever seen before. Descartes’ challenging of the traditional ideas and proposing new ones in which challenged the minds of the individuals, as well as trying to convince the masses that dreaming had some sort of value for an individual that would carry on into his conscious world. Throughout these different ideas lied his main notion: the dreams produced in the human brain while unconscious are not false or fiction, rather, they present the truths that lie in our very minds and therefor should hold value to the dreamer himself. Descartes believed

René Descartes was an extremely influential 17th-century philosopher and came up with many ideas that still persist to this day. One of those ideas was Cartesian skepticism, which states that “the view that we do not or cannot have knowledge in regard to a particular domain,” knowledge, in this case, is justified, true, beliefs. He first comes up with his idea of skepticism in the first part of his work “Meditations On First Philosophy,” aptly named “Of the things which may be brought within the sphere of the doubtful.” In his first meditation, he discusses his doubts with sensory illusion/error, possible dream states, and regarding deception by an evil demon. However, after dissolving his first two doubts, he gets stuck on the third and

With the emergence of the scientific revolution in the 17th century, views of society and nature were transformed throughout Europe. There were great developments in mathematics, physics, astronomy, biology, and chemistry. The world and its views were changing, and with that change, came a new change in thought, a new change in philosophy. Apart from ancient Greek philosophy, which was centered on finding order in a vast variety of things by searching for a fundamental amalgamating principle, Descartes sought to establish order via some fundamental division. Descartes understands and expresses that what we know about our mind is more definite than what we know about the world outside our mind. Descartes’
