Can Anyone Help Prove My Existence?

The discussion revolves around the philosophical challenge of proving one's own existence, prompted by a class assignment. Participants highlight that while direct proof may be impossible, evidence can suggest existence, such as visibility or interaction with others. The conversation references Descartes' famous assertion "I think, therefore I am," emphasizing that thinking implies existence. There's also a debate about the vagueness of the term "existence" and the need for clear definitions and axioms in philosophical arguments. Ultimately, the assignment encourages deeper reflection on the nature of existence and the assumptions underlying such proofs.

I would call your mother and have her testify that she grew you in her belly for 9 months. Then spent probably 8 hours in labor that she probably felt like she wouldn't come out of alive. After you provide this proof proceed to punch this guy in his face for making you spend a considerable amount of time on nonsense. :)

Then have her co-host The View and explain how the Earth is flat.

Yawn.

Ask your professor if axioms of any kind are "allowed" in your proof.
I kind of think this is the inklings of what the professor is looking for.

A common question on interview tests for programmers is "How many gas stations are there in City X?"

It's not about the answer, it's about the process.

What questions come to mind? What are your assumptions?



All you people who are poo-pooing this assigment: are you saying that the OP will simply not benefit from thinking through an abstract problem in terms of the process of problem-solving?

OK, I think we have wandered far enough away from the topic now. This is not a debate about the value of philosophy classes. Do that in another thread if you wish, but please be respectful of each other. o:)

To the OP: there's a whole field of philosophy dedicated to that single issue of "existing": it is called ontology. The interesting thing about philosophy is that you are not supposed to take for granted what everybody else is taking as an evident starting point. That has of course the merit of making you think about things which are usually not considered "open to consideration because self-evident", but it has also the problem of not giving you any "basis to begin with". In fact, even mathematics has this problem. You cannot begin mathematics from the beginning. You need some basic intuitive input.
As to the question by the professor: why don't you set out to prove the opposite: try to consider that you don't exist.
Assuming that only you (as a subjective entity), but not the world (nor your body), exists, is a well-known philosophical stance too, called solipsism. It cannot be contradicted, but still assumes that you exist.

The problem is that we don't even have a good definition for what is existence

I don't see a problem. An ideal definition is not essential. We only need to agree that what does not exist does not have any property, does not do anything, does not matter. Don't we agree on this? If so then to prove existence you just have to pick "thinking" as a property or action, with a direct corollary that what thinks must exist. I could have picked some other property but "thinking" has the benefit of being impossible to deny, don't you think?

This has been a good discussion :smile:

since the OP referred to "the Matrix movie", i'll give you a link at the end of the post, but now let me just say this: it is often very difficult to agree on such issue because you/I may have a large/smaller set of properties you may want to test, and someone else may have yet another set in mind. You could feel that you exist as a "real" (the quotes because I haven't defined what I meant by "real") entity in your dreams, for you feel pain if someone hit you or you can feel your surroundings. But would everyone come to the same conclusion? In order to "prove" things you need to do it a way such that it does not depend on perspective, taste or envoirmental influences. That's the major obstacle. If everyone in the world has similar beliefs, we won't have war in the middle east!


If so then to prove existence you just have to pick "thinking" as a property or action, with a direct corollary that what thinks must exist. I could have picked some other property but "thinking" has the benefit of being impossible to deny, don't you think?

Now, the only question we need to answer here is that should we see computer characters with AI which reside in a virtual world "exist" in the same way that we do in our "real" world? mind you, different ppl may have different opinion on this.

My first urge is to go with Kurushio95 #7 post suggestions. However, Consider that the prof'' is a solopsist. The proof he wants is one a solopsist is always trying to get. Not for himself though. The solopsist is the only existence he needn't prove. Lonely though. Always looking for evidence that all you zombies out there are real. Appear to the professor in his/her dream and give him a password. Put the word on paper and give it to him. If done correctly you'll ace that class.

Or, something along this line. I do not exist outside of your presence. When you leave I am but a ghost of memories that upon your death will be annihilated.

You can prove to yourself that you exist, and I hope you learn to be happy with that.

But we don't ! The middle-east doesn't exist! :-p

I don't want to spoil this thread with tasteless mathematician's jokes, but... try uniqueness first, I think it's easier.

(Sorry for interfering but couldn't let the chance go :smile:)

Since person a) used the same logic as person b) to defend their point of view.
And I compared person a) and person b) on that basis, your implication that my intent was based on hatred of a gender is nothing more than an insult. In which case, I will respond in kind.

Your opinion sounds a little stupid.

You only have two choices: Either you are something or you are absolutely nothing. If you are aware that you have two choices then you are something (something that knows at least it has two choices). We are still trying to determine exactly what this 'something' is.

So ya...my philosophy teacher assigned me to write an essay proving that I exist. Being fairly new to philosophy I've got no idea how to go on about proving that I exist, which sounds pretty weird. I've been around the philosophy section of this site a few time and I got to say some of you guys have given me more to think about then any other human being I've ever known in my life. I think there are some great minds here. To get to the point, I need help on how to prove I exist, I haven't thought this much about my existence since the last time I saw The Matrix while high.:smile: So can anyone help me out? Thanks in advance.

If “I” is allowed to be an indeterminate, look up Descartes’’ “I think therefore I am” argument.

And what nothing is.

Ok I'm just going to throw this in...I define existence in two parts;one i exist in a conscious state and two i exist in a "physical" state (couldn't think of a more appropriate word). I think is important to first define the word "existence" because it makes it a little easier, kind of like a foundation to build on.
My definition is of course open to correction. :)

Ultimate nothing: we do not know what it is or is not.

Primary nothing: empirical nothing--what is there when we can detect no thing with our senses or sensors.

Secondary nothing: a rational construct that describes the lack of something.

Nothing: what does not matter.
Something: what matters.

Can't one prove their existence based on the acknowledgment of others. Certainly one cannot prove them self existing, and it would take more than one person to prove that they are existing. If only one person realizes your existence it's kinda like being an imaginary friend.It doesn't really count. But the fact that you have family and friends that acknowledges you, proves your existence doesn't it? If you look at it like your in the movie The Matrix, it still means that you exist, your just not fully aware of it and that maybe it. Some of the crazies of society might be the most ingenious, just because they can differentiate between what is real and what isn't, what exist and what doesn't.

The question is, how do you know they aren't an illusion.
You can't know for certain.
But you can know for certain that you are thinking, because you are thinking about whether you exist and you can't avoid certainty of that.

Try killing them, then spend the rest of your life in prison and let's see how much of an illusion that is. Sorry but I disagree with what you just said about the people around you being an illusion. That just adds more unnecessary questions and we would be going in circles.

Not a fun one, and neither is severe case of paranoid schizophrenia.

But, really, if all you are going to do is dodge the question, why respond at all.

Wouldn't proving something exists also prove that it is real? Wouldn't a photograph also prove if something exist/real, since a camera only captures reflected light off of a surface?

What I'm trying to say is, if someone might be illusional ( like you are suggesting) then how do I know you're not fake and how do you know I'm not fake. Doesn't add up. If a living thing is illusional, then so is nature, the Earth and pretty much the whole universe.

So by believing that you exist, you exist? That would just mean that that inside this vast universe only you are the only one that exist, because you wouldn't be able to prove the existence of others, just yourself.

What separates an illusion/dream from reality? Its the ability to feel emotion outside of our five sense. Our brains can be easily tricked, especially our five senses. One can recreate taste, sight,smell, hearing and touch. But one thing we can not recreate is love, hate,etc. If we were all born into this universe alone, and that everyone around us was an illusion, how would be able to experience these emotions? Emotions must be taught and experienced fist hand, if one was sealed away from the outside world these emotions would be unfamiliar to this one person because they would not know what this is. They would probably feel it but they would not recognize it. Haven't any of you watch a cartoon or movie where the little kid goes " It feels weird right here(points to heart)" and then the dad goes "You're in love son"

The reason we are aware of these emotions means we exist but it must be guided through another being that has also experienced it.. The love from your family directed towards you is clear, so in the process you learn what love is. Emotions is not something that can be recreated through a computer, or in our minds if we have not experienced it first hand with other beings.

There was no Nobel Prize for Philosophy in 2007. I wonder why? Too much of philosophy is still in the seventeenth century. Just because you do not understand something does not mean it is not understandable.

Assuming the camera is real.
