Epistemology - Truth versus belief.

This is assuming that there is an “external” at all. You say “all that is external” yet provide no evidence that it is.

I know, for sure, that there is a computer, a sensor, and a readout. It can be corroborated by multiple “not me” sources. ALL EVIDENCE THAT CAN BE PROVIDED SHOWS THAT THERE IS A COMPUTER.

Now, can you provide evidence to the contrary? No, you can’t. You admit that you can’t. I can. I have provided the burden of proof for my claim.

You can say “nuh uh!” all you want but that still won’t change the fact that the burden of proof has been satisfied. You’re now making a claim that it’s not true and PROVIDING NO EVIDENCE for it.

So, until you can (you say you can’t), why should I even bother?

This isn’t like the “claim” that there is no God…because there is NO EVIDENCE FOR A GOD. Just like there’s no evidence for this “external” thing to which you speak. This “external” is now YOUR claim. You must satisfy it with evidence. You can’t, so it remains a baseless claim.

Well the computer is definitely there, it is a human invention after all. However the fact that it’s made from real metal and plastic and not information pumped into your brain is still up for debate.

That’s not up for debate either. Until there’s evidence that is is, you do not have a leg to stand on.

I, for one, am sick of this solipsistic bullshit.

It’s identical to the claim that the “moon is made of rock” and “the moon is not made of rock” are equally valid standpoints. Let’s take a look at what we have:

Moon is rock: Evidence provided: 100,000+ pieces
Moon is not made of rock: Evidence Provided: 0 pieces.

Yet, they’re equal? Bullshit.

No, what I’m saying is that there is no evidence beyond what our conscience perceives is external. You are saying that you are going to use sources you can’t verify to verify sources you can’t verify. Use a common rock for example. You point to a rock and say ’ that’s a rock. ’ How do you know it’s a rock? Well because it looks and feels like a rock. Vision and feeling are interpretations of an outside world. So that is assuming there is an outside world. You say you corroborate with other people. Well that assumes that there is an outside world, or an alternate realm to your consciousness. You check with scans on a computer, readouts on screens, but you can’t even verify the very senses you use to perceive these tools.

You aren’t even getting the basic concept I’m putting forth. I propose nothing. I’m providing a starting point. I say ’ I exist. ’ I must or else I can’t propose my own existence. That’s called a self proof. So next I say ’ there is x that isn’t me ’ . Unfortunately this isn’t self proving. I need to figure out how to determine something x that isn’t just a part or function of my consciousness. How do I do this?

You say that you verify it by checking external sources. Which is a non-starter, because you can’t say there is an external at all without some form of verifiable way of identifying an ‘external’ .

I would be inclined to say ’ I have senses that relay information from the outside world. ’ But again, these senses like sight and sound are not self verifiable either because they are simply interpretations or even just manifestations of your consciousness, you can’t verify anything about the origin of any ‘input’ or manifestation of your consciousness.

For the sake of argument, let’s say the assumption of an outside world is correct, and that the idea of our mind as a brain in the head of our body is correct. In such a case our brain is a collection of synapses etc. interpreting input. So, how does a brain interpret the outside world and how does it verify the outside world is there? Well it collects information, yes? It uses electrical signals travelling through the optic nerve to be interpreted as optical data. Signals through your system also interpret electrical signals for smell, touch, etc. The brain in question receives signals and interprets these signals. How does this brain determine the accuracy of these sources without the ability to experience anything outside of itself? To be perfectly transparent, it really can’t. It’s just a brain that houses a consciousness.

What we do is collect as much of what seems to be input, and then organize. We assume SOME of what is collected is accurate, and try to compare, and verify. On the most basic level, we DO assume that at least some of what we perceive is useful. If we don’t then everything gathered, all evidence cannot be verified and thus means nothing. Mountains of inaccurate, or falsified evidence equates to no evidence. The evidence you suggest cannot be verified, so the evidence you suggested doesn’t amount to anything more than you saying your senses indicated you observed the outside world, and when pushed to look for evidence you provide sources in the outside world as if they are self verifying, when even these sources are still just being perceived.

This may come off as a damnation of evidence, but it isn’t. Pointing out restrictions, doesn’t mean that you give up does it? On the contrary, I think it makes it even more important to be critical of everything, even our own sensory input.

Many people will say ‘I know’ as if it’s a term that can be easily used. These people don’t KNOW anything they claim to KNOW. Yes we must start from some basic assumption about our interpretations of reality, but that doesn’t mean that we throw away the only tools we have. If this were to be done and reality DOES have some bearing then ignoring the tools we have is dangerous. What I mean to say is, no I can’t prove to myself than I’m standing on a bridge at all, but that doesn’t mean that I’m not. I can’t prove I’m not just a brain in a jar hooked up to electrodes, and this brain thinks it’s in a body that is on a bridge. None of that possible illusory of life means it’s a good idea to ignore my senses and my knowledge of gravity and what it implies. To put it bluntly, I should not just stroll off a bridge.

The point is that I can accept that I assume reality is in some way as I perceive it. I have to really. We cannot use this as an argument though. I can assume the person I’m talking to isn’t really there, but it’s not a good start. It doesn’t benefit my understanding to do so.

It’s just annoying that when you provide evidence, and you get the response. ‘You can’t really know anything.’

No, I can’t really KNOW anything. But there needs to be a start point or else conversations don’t go anywhere. Where do you go in a rational conversation, or discovery if at every turn you say to yourself ‘I can’t prove any of what I’m perceiving is true so I’m going to ignore it’ . That’s silly.

So it shouldn’t be used as a conversation stopper. It does come up a lot in religious conversations. When people say that evidence for ‘God’ is impossible because he/she is non-physical. You have to stop because it’s not a useful conversation. Could it be true? Yes. Is there evidence against it? No, not really. But it’s not useful in any way because anything non-physical that is in no way perceptible isn’t impacting on us in any way.

It also happens when people make claims about psychic abilities, or mystical abilities. When pressed you’ll often times get responses like ’ you don’t know ’ or ’ you don’t understand ’ this is followed by obscure claims of differences in understanding or that it’s something they ’ just know ’ . When you point out that it’s impossible for them to just know and that you have evidence against their claim, they may reply with ’ well we can’t really know anything ’ Yes, I must concede, I can’t really know anything about anything, but there still needs to be a starting point.

IF what we perceive is real, but none of us ever accepted anything as real, we would never have gotten to where we are. But we make that first assumption because we must. It’s not an excuse to ignore evidence. In fact, i think it means that we must work towards creating strong evidence. not gather weak evidence and twist it to make it more palatable to what we want to believe.

This whole thing is WAY overly long as is, but for the closing TL;DR version. I disagree with Danielsangeo. I can accept that I cannot know anything outside of myself. I still think it’s dumb to just sit on it though. If a conversation degrades to this initial point then I just exit because it’s useless. How far does everyone here go back? If you think you don’t make any assumption where is the line where you say ’ this is real’ ?

“No, what I’m saying is that there is no evidence beyond what our conscience perceives is external.”

…beyond? This is your claim and you have to provide evidence that all the evidence that we have is somehow wrong. Again, I’m getting fucking tired of this solipsistic bullshit. We have evidence and if you have something to provide that shows that this evidence and our observations are wrong, fucking PROVIDE IT. Stop tapdancing and PROVIDE IT.

You can’t. I know you can’t.

I think you got robbed by the same mysterious people that steal guitar picks. Seriously, I can never find them, most of my picks have disappeared to never be seen again.

It is probably also the people that steals your socks while they are in the washing machine.

Hah! The washing machine/socks one is easy. The socks are, usually, the smallest item in the washing machine. It’s possible that the washing machine is eating them. They can sometimes get tossed in such a way that they fall out of the drum as it’s turning, or get sucked up underneath the agitator (if there’s one in your machine). Your missing socks probably are stuck inside the machinery somewhere and you’d have to take your washing machine apart to find them. Next time you look into the machine, look to see if there’s a gap between the door and the drum or the drum and the agitator. This is probably where they’re going.

Or, they could fall behind the machine before or after the load while you’re taking the clothes out or putting them in. Or, if you’re using a public laundromat, they could get stuck against the side of the drum, out of sight. I have not only lost socks in public washing machines, I have gotten OTHER people’s socks!

At this point you are just being obtuse.
You know perfectly well that isn’t a claim. It’s a statement of logic. You keep saying you have evidence, but you haven’t provided anything. It is not a claim to say I don’t know, and I don’t think that I can. It is the responsibility you owe to yourself to question your own perception. If you don’t then YOU assume your perception is accurate. IT IS NOT A CLAIM TO QUESTION YOUR OWN PERCEPTION.
All you have done is repeat flawed arguments that it IS a claim, and that I need to provide evidence I don’t know. YOU are making the claim that YOU know something that I don’t claim to know, and then you say you have evidence, which is the same evidence I should have. Since I cannot verify the source, and thus the authenticity of the evidence, then I still can’t know for sure. You claim that you do know and that somehow you can verify the evidence, but you haven’t said how…

Also, if you are so sick of the conversation you can feel free to leave it. You certainly haven’t added much to this point.

Yes, it is. Your claim is that our perception cannot be trusted but you cannot say for what reason.

Can you tell me WHY “my perception” would be flawed? You aren’t saying “I don’t know”. You’re saying “no” in the face of every bit of evidence that says “yes”. And I want to know WHY.

bur: Awesome. Thanks!

what this discussion boils down to is, no, we cannot know anything for sure. But we make certain simple, essential assumptions that are necessary to understand the world around us, and from that follows our understanding of evidence and, as a result, science.

Unless your perception can be validated by a secondary source, all your evidence is gathered the same way mine is, and that is through my senses. Unless you can verify the source of anything you perceive in a way that I cannot, I don’t see how you can make any claim about the authenticity of your evidence.

I put forth the question to myself. Can I verify any of the evidence for the outside world at a basic level? Any evidence I receive indirectly through my senses cannot be trusted, because they are the delivery system in question. Since I don’t possess any way to provide verification, I can’t make a definitive claim. To acknowledge that it could be true or not true, and without verification I cannot know for sure isn’t a claim.

My perception is validated by secondary sources all the time. And tertiary sources. And quaternary sources…

I say that there’s pasta in a pot. How do I know that there’s pasta in a pot? I can see it. I can smell it. I can taste it. I can touch it. I can hear it if I lift some of it up and drop it back down as it hits the surface of whatever I’m dropping it on. Experimentation leads me to believe that it is pasta in the pot.

Now, for some validation. I ask my brother what’s in the pot. Using his senses just as I did, he announces with conviction that it’s pasta in the pot. That’s secondary validation.

Now he asks my father. Same deal. Father announces that it’s pasta in the pot. Then he asks the next door neighbor (yes, this is getting silly, but let’s keep going). Again, pasta in the pot. His friend? Pasta in the pot. His friend’s neighbor’s first cousin? Pasta in the pot. Thousands of people this goes through, every single one of them announcing with conviction that it’s pasta in a pot.

If that isn’t validation, I don’t know what is.

Can I verify any of the evidence for the outside world at the basic level? Can I trust my senses? Most of the time, my senses are accurate and I CAN verify in cases where I’m not sure. That’s where solipsistic worldviews fails. I can verify.

I believe that a fork held above the surface of the Earth will fall to the Earth if I let go of it. I can verify that by holding the fork above the surface of the Earth and letting go of the fork and watching what happens. I verify that gravity exists because everything in my room is sitting on the floor. Nothing is floating, unless I get something that can temporarily and partially counteract the force of gravity such as a helium balloon, but popping said balloon would bring the pieces right back to the ground and following said balloon as it floats through the air, it cannot permanently escape the gravity of the Earth; it’ll either pop from the lack of air pressure or the helium will seep through the porous material of the balloon and it’ll eventually fall back to the Earth from the weight of the balloon.

I conduct millions of experiments per day. My ‘assumptions’ are validated 18-ways to Sunday. At no time does something, anywhere on the planet, millions of people observing billions upon billions of things, and nothing floats and in fact, Earth’s gravity would still affect something even distant stars and galaxies. Sure, the affect is nearly zilch, but it’s not zilch. And we are affected by the gravities of other objects in the cosmos.

You claim that I can’t verify my senses. I say I can.

You claim your eyes ‘see’ the pot, but all your brain knows is that electrical impulses are stimulated in you visual cortex. Your brain interprets touch, and sound. Your experiment proves that your brain perceives a pot of pasta, but doesn’t verify your senses.

No, this is still just more validating that you HAVE senses, because you haven’t verified their authenticity yet, you can’t even verify you are even physical, let alone talking to someone / something physical.

All of this information arrives to you through a system that cannot be verified.

It seems like the last part is true.

No you can’t verify your senses ever have been accurate. At least not through any of they ways you’ve put forth so far.

You simply are NOT getting it, and I’m running out of ways of explaining it.

You’re suggesting that my senses aren’t accurate. And I can’t figure out WHY. And you are REFUSING TO TELL ME. You just keep insisting that I can’t verify my senses over and over again.

Because you cannot verify them in any way. At least not in any way that doesn’t rely on your senses.

Why can’t I verify them in any way?

Do you have any way of gathering information that isn’t through your senses?
Even what you claim is gathering information from outside sources is delivered to you via your own senses.
