Indeed, in the statement "I think therefore I am" there are several statements presumed certain a priori and they go well beyond the convention that doubt is a form of thought, for the whole statement presumes knowledge of semantics involved, that is of what "I", "think", "therefore" and "am" mean and more significantly some logical principles such as identity, non-contradiction and causality! 2.

WebThe Latin phrase cogito ergo sum ("I think, therefore I am") is possibly the single best-known philosophical statement and is attributed to Ren Descartes. The 17th century philosopher Ren Descartes wanted to find an absolute, undoubtable truth in order to build a system of knowledge on a solid foundation. But if I say " Doubt may or may not be thought", since this statement now exhausts the universe, then there is no more assumption left. It was never claimed to be a universal rule that applies to all logic, it was merely the starting point where you do not assume. Hows that going for you? @infatuated That is exactly what I am disputing. Descartes did not mean to do this, but establish a logic through which he can deduce existence not define it.

The argument by itself does not even need the methodic doubt, the rest of the metaphysical meditations could be wrong, and still the argument would stand correct, it is independent of all those things. The way I see it currently, either cogito is a flawed logical argument, which cannot be the basis for any future logical premises. mistake or anyone clearly admitting Descartes's.

But how does he arrive at it? New comments cannot be posted and votes cannot be cast. I view the Cogito to be just an attempt at logically establishing what is evident to us through intuition but the argument doesn't at least explicitly address many questions that may emerge in subseqeunce which are however not really to its detriment if we note that no intuitive knowledge can be expressed in a logically sound expression maybe because human intuition doesn't work discretely as does logical thinking. Is Descartes' argument valid? The first issue is drawing your distinction between doubt and thought, when it is inaccurate. Therefore, I exist. There is NO logic involved at all.

Learn more about Stack Overflow the company, and our products. First, to Descartes "doubt is a thought" might be close to what Kant later called analytic, i.e. Descartes starts with doubting, finds an obstacle, and concludes "I, who thus doubted, should be something".

My idea: I can write this now: In fact, The process Descartes is hoping that we follow and agree with his intuitions about, is supposed to occur "prior" to any application of logic or science, as the cogito ergo sum is supposed to operate as the first principle upon which any subsequent exercise of logic can assuredly stand, without further questioning, provided that we agree intuitively with Descartes' process of establishing that first principle, as he presents it. This philosophy is something I have never truly jumped into, but I may need to wade in and try it out. Webvalid or invalid argument calculator Corofin News Archive Corofin-Kilnaboy Notes for Thursday Oct. 29th. Then Descartes says: Furthermore, I find it noteworthy that, among all the prior premises and definitions presumed by our mind, existence can be argued to be the highermost assumption in each act of thinking. You can't get around Descartes' skepticism because if you reject direct observation as a means to attain accurate information (about conditional experience), you are only left with reasoning, inference etc. Do you even have a physical body? But, is it possible to stop thinking? First off, Descartes isn't offering a logical argument per se. "I think therefore I am" is a translation from Rene Descartes' original French statement, "Je pense, donc je suis" or as it is more famously known in Latin, "cogito ergo sum". And as I observed that this truth,I think,therefore I am,was so certain and of such evidence that no ground of doubt, however extravagant, could be alleged by the Sceptics capable of shaking it, I concluded that I might, without scruple, accept it as thefirst principleof the philosophy of which I was in search.

Go ahead if you want and try to challenge it and find it wrong, but do not look at the tiny details of something that was said or not said before, it is not so complicated. Moreover, I think could even include mathematics and logic, which were considered sciences at the time. Not a chance. For Descartess argument to work, I would need to make a contradictory second assumption, which would be Doubt is definitely thought, and I cannot doubt that. I am has the form EF (Fx). Having made a little diversion now time to sum up the answer: Cogito is an imperfect argument if taken as an argument as Descartes didn't comprehensively address and follow many questions and implications associated with what can be considered a useful mental exercise. According to Ren Descartes, one thing that you cannot doubt is your own existence as a thinking thing. Descartes begins by doubting everything. This appears to be not false equivalence, but instead false non-equivalence. First things first: read Descartes' Meditations and Replies. Every definition is an assumption. There is no logical reason to doubt your existence if you can question your existence as you are required to pose the question. Kant, meanwhile, saw that the intellect depends on something prior. And finally, when I considered that the very same thoughts (presentations) which we experience when awake may also be experienced when we are asleep, while there is at that time not one of them true, I supposed that all the objects (presentations) that had ever entered into my mind when awake, had in them no more truth than the illusions of my dreams. Argument 3:( We need to establish that there is thought, doubt and everything to go ahead) We maybe then recognize the genius of Muslim philosophers such as the 12th century philosopher, Avicenna, who had already cited the essence of Cogito argument (centuries before Descartes) only to dismiss it as invalid based on the claim that we can never experience our thoughts separate from our existence, hence in all acts of thinking the existence of self is presumed. The second thing these statements have in common, is that they lose sight of the broader evolution of human history. I'm going to try to make this clear one more time, and that is it. This brings us back to the essence of the Cogito, however the question remains, did I really need to deduce my own existence if it can be shown that it is an evident prior intuition. So you agree that Descartes argument is flawed? This is why in defending cogito against criticisms Descartes disavowed it as an inference, and described it as a non-inferential surmise, where "I think" (replaceable with "I doubt") simply serves as a reminder of the experience that motivates "I am", not as a premise of an inference: "When someone says 'I am thinking, therefore I am, or I exist' he does not deduce existence from thought by means of a syllogism, but recognizes it as something self-evident by a simple intuition of the mind.". There is no warrant for putting it into the first person singular. Its like if I were to call your argument invalid because I don't think you should use the word must. Hence, a better statement would be " I think, therefore I must be", indulging both doubt and belief. Written word takes so long to communicate. Until Mulla Sadra a 17th century Muslim philosopher who brought about an entire revolution to peripatetic philosophy by arguing from logical and ontological precedence of Being as well as its indefinition and irreducibility that only being captures the true essence of God as God and Being seem to be identical in these properties! Now after doing this, he cannot establish existence for certain, because his first assumption does not allow the second assumption which he has made, because that reasoning can only be applied by NOT doubting his observation. Descartes starts questioning his existence, and whether or not he thinks. (They are a subset of thought.) He may not be able to doubt that "doubt is a thought" either, on the basis of analyticity, but again, this is moot. And you do get credit for recognizing the flaw in that assumption and the weakness in the argument. The last one makes one less assumption, has no paradoxical rules and is absolutely true. You have less reason to doubt observation in a world showing and acting impermanently and empty of Self, because the deceiver, a 'thing' posited outside of observable experience - a being hypothesized as permanent, a consistent net force in some direction across All (whether making left seem as right or peacefulness seem as violence) - is definitively unobservable in a relational world (the act of observation is by itself a condition of observed properties). (Rule 1) Rational self-awareness, then, is the undoubtable, absolute certainty that Descartes was looking for as foundation to all knowledge. If you find this argument convincing, stick around for a future article where I will argue for what I call the logical uncertainty principle, claiming that everything has a degree of uncertainty, even Descartess cogito argument. Williams talks about this in his Descartes: A Project of Pure Inquiry, Cottingham in his (very short) Descartes, and and Banfeld in an article, "The Name of the Subject: The "Il"?," which you can access on jstor here. andrewflnr 5 hours ago | root | parent | next. Since you mention me, I'd like to point out that I was commenting on two things: One was the other commenter's setup, and the other was Descartes in general. Fascinating!

No it is not, you are just in disagreement with it, because you mentally would prefer your handhanded and have certainty on a realm where certainty is hard to come-by. My observing his thought. You can't doubt doubt unless you can doubt, so your arguments about doubting doubt are paradoxical if anything is. WebThe argument of $ 0 $ is $ 0 $ (the number 0 has a real and complex part of zero and therefore a null argument). @Novice how is it an infinite regression? At this point I want to pinpoint it out, that since I or Descartes, whoever does the thinking, are allowed to doubt everything, we can also doubt if doubt is thought. You seem to think that, by doubting that doubt is a form of thought, you can beat Cogito Ergo Sum. The poet Paul Valery writes "Sometimes I think, sometimes I am". Here is a man who utterly disbelieves and almost denies the dicta of memory. Very roughly: a theory of epistemic justification is internalist insofar as it requires that the justifying factors are accessible to the knowers conscious awareness; it is externalist insofar as it does not impose this requirement. He notices an idea, and then he thinks he exists. (3) Therefore, I exist. In that, we can look at the concepts/structures he's proposing, and we can certainly put forth a charge similar to what Nietzsche did (depending on our other notions - as mentioned elsewhere).
