Is Thinking Essential for Existence?

AI Thread Summary
The discussion revolves around the philosophical assertion "I think therefore I am," originally posited by Descartes, and critiques its validity as a proof of existence. Participants express skepticism about the soundness of this statement, arguing that while thinking implies the existence of a thinker, it does not serve as a universal proof of existence to others. The conversation explores the nature of existence, suggesting that existence may persist regardless of one's ability to think, and even in hypothetical scenarios like a "Matrix" or as a figment of imagination. Key points include the distinction between thinking and believing, with some arguing that belief actualizes thoughts into reality. The dialogue also touches on the complexities of defining existence and reality, proposing that existence could be context-dependent. Observations and interactions with the environment are suggested as potential criteria for proving existence, while the challenge of proving non-existence is acknowledged. The discussion highlights the philosophical intricacies of existence, reality, and the subjective nature of belief and perception.

"X is non-existent" then you are also saying that "X exists so that 'X' --> does not exist

Also, (though this may seem redundant, I would still like to emphasize this) X=X . Furthermore, by ad absurdum proof, the statement you made is self contradictory. So it is false for anything to exist and not exist at the same time.

that only applies to x not exsisting in a material form in a material form
What do you mean by material? If you mean matter, then yes because that is the only way anything can exist. Furthermore, it seems that you have "energy" (which is not a form of matter and therefore does not exist ) in mind. It doesn't exist, it is merely a concept

for example "a time machine does not excist" by that logic I just created a time machine by denying it's exsistance.

NO. "x" cannot exist and exist at the same time (with a definite probability). prove this otherwise if I am mistaken.

the original quesion this should have asked can you prove you exsist in the physical world.

Is there anything besides the physical world? This depends on the definition, so...
physical- anything which exists -->interacts with the environment.


I have a proposition. IS IT POSSIBLE THAT THIS DISCUSSION IS FUTILE SINCE IT CONCERNS SOMETHING WHICH MAY BE IMPOSSIBLE? How can someone prove they do not exist, when doing the task requires a conscious being to do it?

Possible to stop thinking? I think you misunderstand Descartes' definition of "thinking." Thinking is used more in the sense of consciousness in the Cogito proof. Once you lose consciousness (as in death), how do you prove your existence?

I going to have to disagree with you on this one. For Descarte (as echoed by some functionalists today) thinking is consciousness. Personally I don't believe that for a second. Thinking is something consciousness can do, but it doesn't define it.

Locrian said:
Hmm, would you care to elaborate on this? I can't see any reason to accept it as true that one can stop thinking at all, much less still be aware of anything once one does.

You mean you can't stop thinking. :wink: There is a long history of the practice, and successes. I stopped my mind from thinking earlier this morning, and I do it every morning. It takes practice, but it is possible. If you want to read a little more about it, I talk about it in the "panpsychism" thread in this general philosophy area, and in the "mind to mind" thread over in metaphysics.

what I mean exsist in material form is that you can have ideas, and unless you reguard an idea, ideas aren't made in the "physical world" for example say you have a drawing of a concept car, technically the car does not exsist in what we are used to cars exsisting as, but the idea is something in itself and it cannot be denied, so even if it doesn't exsist out of aluminum and rubber, it exsists as a concept or idea.


for example if I say, a zxcvbnm doesn't exsist, then you ask well what is an zxcvbnm, and I'll say, it's a mind reading device that is shaped like a pink poodle, I mean sure a fully funcional prototype hasn't been created, but it still something, an idea

I think about something ergo i am

Jameson said:
I've heard the phrase "I think therefore I am" as a proof of existence, but I do not find that very sound (and i think i heard that Descartes didn't exactly say that phrase).
Jameson

"I think about something, ergo, I am a viewpoint/point of view, with both metaphysial, and physical aspects/attributes" (Rybo)

There is the metaphysical "I" and the physical "I" that are eteranlly complementary to each other.

Something is a physical thing i.e. some-thing.

Experience preceeds thought i.e. there can be no thinking without a minimally the something to acccess thoughts(mind) with and something to think about(brain).

"X" is only an intellectual, metaphysical, mathematical abstraction that can be representative of a physical something.

Relativity proves it. Light has a fixed speed limit and time exist and is measured by this speed limit. Now the time it takes for someone to try and prove they exist and the time it takes for someone to receive the proof can only attempt to prove things but only in the immediate past. So one can only prove that they did exist but can never prove that they do exist.

So rather then the saying "I think therefore I am" a more true statement would be "I think therefore I was"

You think about something

vincentchan said:

i can't prove your exist, but i am pretty sure i exist

You think about somthing that can only be based on your experience of somethings.

Contrary to popluar "oh i wasnt thinging abut anything" the subconscious and unconsious are always actively processing experience, or recombobulation/aggregate of past experiences, to some degree even if minimally so.

I"dream ergo I am unconsciously processing experience of one sort or another.

Without things there can be no experiential uncosnsicous or conscious conciousness.

Doubting Tom

I think Decartes said:

"I can doubt everything except doubting. Doubting is something. Therefore I exist."

Works for me.

Although I haven't read all posts from what I have seen this is the best answer. Still the question still is not clearly defined. We need a definition of what is meant by 'exist'. This post is correct given my definition.

My definition is that if something exists it is an object of a valid cognition. In line with this definition the fact that we can question our existence is evidence that we exist. As a side note "I think therefore I am" is a perfect reason to establish that we exist as I see it.
 
  • #71
I think therefore i was. That is the only certainty you can have because thinking takes time, and you can never be certian that you exist unless you think faster than light.

I personally believe that we exist, but as far as proof...YES, I think I have some. We cannt prove that other's around us exist (Meaning that if you are reading this, maybe I don't exist to you, I am just a figure of your imagination, like in a dream), but you can prove that YOU, as a BEING, do exist, because if you did not exist...Nothing would exist from your point of view. Think if it this way, while you are in a dream, you are convinced that everything around you is real, you treat the situation as real life, but the beings around you do not exist, but you do, because if you didnt exist, you could not be observing anything.

Perhaps I did not explaine what I mean clear enough, but I think what I said is valid.

Note though that it takes time, not only to experience but even to understand what it means to be existing. Furthermore, how can we know that our logical system is correct, what basis for knowledge does this deduction give us?
I believe we are not to base these things on strict implication but rather on probability. I can surely agree that I believe myself to hold a high probability of existence as I am writting this, though, pre-metalogicly, if this sentance would be correct, I'd exist.
Given this, one may very well go on to try and figure out whether other beings exists or not. Do you percept things? You can hold quite a high probabiliity for this as well. Then, wherein lies the difference between things which you percept who are others and things you percept who aren't others?

I don't know how to address this comment unless you define "logical system".

I am not sure who is reading my posts but no one has given a definition of an existent. Until we define our terminology we can't have an intelligent discussion. By presenting a definition the problem is resolved. The problem is not whether something exists or not but determining what is meant by existence.

Philosophy is very simple it is our thinking that is complicated. A quote by Wittgenstein capture this sentiment perfectly.

Why is philosophy so complicated? It ought to be entirely simple. Philosophy unties the knots in our thinking that we have, in a senseless way, put there. To do this it must make movements that are just as complicated as these knots. Although the result of philosophy is simple, its method cannot be if it is to succeed. The complexity of philosophy is not a complexity of its subject matter, but of our knotted understanding.

If you think you are the figment of another's imagination try running into a closed door.

And what if the really existing person decides that the particular figment in his mind (deluding itself of having separate existence) should experience the sensation of pain the real person would experience when running into a closed door?..:wink:

Your particpation in the world (i.e. interacting with people, posting on the internet) is evidence that you exist. We are certain that this is going on. Any discussion of a God or some level of reality behind the scenes is pure speculation. The question of existence only arises when we consider humans to be independently existing objects that encounter other independently existing object. This is mistaken. We are not isolated thinking individuals in the sense that we exist independently of our environment and the beings who inhabit it. In other words, there is no person without a world to interact in. The whole premise of this question hinges on the incorrect assumption that there is an isolated individual who encounters things, not an individual who exists in relation to its interactions with others and its environment. Basically, your analysis has become too scientific in the sense that you have attempted to isolate the object of investigation by assuming it can be isolated.

Not to you. My own existence is self-evident . . . to me. I may be a dream character in someone elses head, but I have enough autonomy to be 'tricked' into thinking I exist, so therefore, in that sense, I exist. You can't trick nothing, can you?

You people with your dream-reality are going way too far. There is no "proof" necessary to establish existence. This would only be the case if there were an independent self that was thrown into the world and encountered other objects that exist equally independently of anything else.

Ok, but you are doing the same error as everybody, and it is, that you are using something to prove your existence, which leads to an infinite discussion.....

you see, now you have to prove that this forum exists, and if you use the fact of internet, then prove that exists, then if you use the fact of computers, then prove that they exists...etzzzzzzzz

If that is true, it would bem an infinite paradox, because then you wouldn't know what came first, the creation, or it's creation, to say, the egg or the chicken.
