All this skepticism and solipsism is not a problem. It just means that all our conclusions are dependent on assumptions, or "known" within a proposed context. If I'm a brain in a vat, then all my interactions and experiences are made with this rich delusional world, within this delusional world and talk about this delusional world. It's the only world I have, the only context I have, and so anything outside the context is irrelevant to even talk about. Luckily, this world has some internal consistency, enough to be functional and allow useful predictions.

[@timrichardson4018]

Yes! Consistency and reliability, it seems to me, must be the basis of "knowledge." Arguing that we cannot know anything absolutely is to miss the point. Why must knowledge be absolute? It seems then that an appeal to a lack of absolute certainty is a red herring. There is always a degree of doubt to anything we say we know. But that doesn't disqualify it as functional knowledge. What matters is that our model of understanding (knowledge) allows us to make accurate predictions. Since it does, that means our understanding is consistent with our systematic observations of our experiences. If that base assumption is a lie, it doesn't matter. Our understanding is still consistent and reliable WITHIN the lie. Ergo, the question of whether or not our reality is a lie is irrelevant to thoughts and experiences within the lie.

[@someoneonyoutube8622]

but what if there isn't even a world to gather context from and any perceived context you think you have doesn't actually exist? forget the whole brain in a vat hypothesis we need to prove that existence is possible before we can even conclude that being deceived is possible and honestly there could be some unknown variable that it outside of our comprehension that means none of us even exist right now even though it seems so obvious that we do

[@malignor9035]

Robert Stuckey However, the nature of what I am could be illusory. My memories could be artificially implanted, my senses controlled by some force into experiencing what it wants me to experience. Perhaps the only thing that's *definitely* not illusory is my consciousness and subjectivity. But even if we assume this is all an illusory framework, I'm having a discussion. Those who I am discussing with would also be illusory, but ultimately, who gives a fuck? ;D ... The discussion is about this illusory framework anyway, because it's the only thing worth discussing. We can't talk about universes for we have no knowledge or experience. All we have is this "illusion", so (illusion or not) it is the only reality that counts. So all those who push doubt about existence and reality are just denying the very context of the discussion (of any discussion really). They're committing a verbal murder-suicide: if their point is conceded, the discussion becomes worthless, and they can go away & let the grownups talk.

[@timrichardson4018]

It does ultimately seem like a moot point, but some critics of Descartes go even further and say that the only thing that can be known for sure is that thoughts are occurring. We cannot even say for sure those thoughts are actually integrated into a self. Again, seems like a moot point, but interesting none the less.

[@someoneonyoutube8622]

Robert Stuckey however "I think therefore I am" may not actually be as definitive as it appears. for example what if you were a figment of a higher being's imagination? then you would be "thinking" in the sense that you would have thoughts but it would all be because that higher being was imagining that you had those thoughts and you wouldn't actually exist. then the statement "I think therefore I am" could be false and you would not even be able to prove your own existence to yourself.

[@AlexandriaRohn]

00:20 The problem of skepticism... what do you really know? Are you dreaming? 00:50 Ancient Greece has two great skeptical traditions: Academic Skepticism and Pyrrhonian Skepticism. 01:05 Academic Skeptics argued that sensory perceptions don't actually enable you to know anything. Knowledge of the world is impossible for humans. For example, perhaps you are dreaming or perhaps your sensory organs have fooled you. 01:54 Pyrrhonian Skeptics went one step further. They continued inquiring everything without reaching any conclusions at all. Even the question of knowledge itself was left open. 02:25 The dreaming argument. How do you know you're not dreaming? 03:02 Rene Descartes suggested that even if you are dreaming, you should still be able to know a square has 4 sides. But Descartes even questioned that. It simply "feels" right. 03:40 Descartes formulated an "evil demon"/"evil genius" argument where an evil genius is fooling your sense perceptions and even basic things like your mathematical intuitions. 04:40 The "brain in a vat" argument illustrates a brain that is controlled by a supercomputer that generates simulated experiences. 06:03 Typical skeptics don't actually argue that you are a brain in a vat. For them, the possibility of the scenario is problematic enough in itself. 07:08 These 3 arguments: “Dreaming Argument”, “Evil Genius”, and “Brain-in-a-vat” are known as “Global Skeptical Scenarios”. The raise doubts about virtually everything. 07:15 Skepticism doesn’t have to be global. It can be local skepticism as well. 07:27 For example, you can worry about your knowledge of the past. 07:56 Single fact skepticism can be about particular knowledge. For example, a quick glance at the clock may not be enough to determine if the clock was actually working when the time was read. Does this person _really_ know? What is the probability of error?

agreed, i didnt choose to come here, i came to this video while searching for arguments against skepticism so i dont go insane but it isnt helping

[@BresciGaetano]

​@@thatgirlray2765Actually there Is no argument against skepticism itself. Allthought we can easly demostrate that skepticism for it's "selfcontained infite" Is as much pointless as much it's bottomless after a certain point. Now to tell where that point could actually be Is something hardly demostrable without some assumptions... And saddly assumptions are not so friendly skepticism. But... On a personal level i find usefull to keep always both path as valuable and so coherently immagine two solution for any given problem up to the limit that the skeptical or the beliver side won't find themselves completly usless. Let take as an example color perception. There Is no way to be sure the mental immages we create of a color is the same of another person, yet we can quite confidently recognize the same shade with the same name and we percive the same spectrum of contrast (complementary colours). Hence there is no need for further skepticism if all what we are aiming for is to agree on a description. Now let's talk about God. If we are talking about a being outside our reality omniscient and omnipotent there is no way to demostrate it's existence or negate it. Obviously from a phylosophycal standing point, set aside for a ma moment the possible sociological, psychological motivations, and anyway that's about how a deity can be used/served by a religious organization. Now from a practical point of view there Is totally no difference if it exist or not even from a "final judgment" standing point. If it's really allknowing acting good just in fear of him won't help nor would hurt acting as a respectable living being even if you don't think about it's judgment (seem even better). Ofc this last part imply a logical diety and not an heavly emotionally driven one. If you live in Warhammer 40k universe i'm sorry that all that reasoning does not apply...😂

[@letsomethingshine]

Is to think without doubt a good thing? I am aware that to lack doubt is to think imperfectly and fallibly. We even have words for this: naivety and gullibility (both of which are relatively good to establish a strong society with minimal in-fighting). So is to think always doubtful and doubtful about doubtfulness a good thing? Neither is likely to be practical. Although lies can be practical, including lies we tell ourselves. Lies can also be detrimental, even if we tell them only to others. A good understanding of a good balance upon correct context is always important.

while I can appreciate this video for what it is, that type of extreme skepticism doesn't do anyone any good. all it will ultimately do is drive you insane. for the sake of sanity, one has to believe that one's own experiences are real and hold meaning and value, at least for the individual. if you can see, touch, smell, hear, taste, or sense something, you can conclude that it exists on some level, simply because if you assumed it didn't, you would be in denial.

[@AntiCitizenX]

Does knowledge have to be absolutely perfect and certain in order to qualify as "knowledge?"

[@daltontonga5761]

+AntiCitizenX Judging by the first video I think the series is moving towards the idea of knowledge as justified, true belief. Certainty doesn't have to be a requirement for justification as long as it can provide a sufficient rationale to support a particular belief, and sense data can potentially be justification in this sense. It seems to me that the global skepticism thought experiments hinge more on what's true, since one could potentially have justification (depending on what counts as justification) for believing that there is an external world given the parameters of the thought experiments even if this is not the case. And these thought experiments largely seem to be working off a correspondence theory of truth. So if one doesn't accept correspondence theory in favor of, say, the coherence or pragmatic theories these thought experiments become moot as far as knowledge is concerned. I'm curious what the proposed solutions are going to be in the next video and whether they relate to how one conceives of truth.

[@AntiCitizenX]

Dalton Tonga I'm actually heavily biased towards pragmatism. Correspondence theory has a lot of problems.

[@PaulTheSkeptic]

+AntiCitizenX I would say of course not. That would mean no one would have any knowledge. I believe the solution to the problem of skepticism is to have "properly basic beliefs". This is just based on my limited but growing knowledge of philosophy. There's so much to learn in philosophy and I often feel like I haven't scratched the surface.

@5:50 Even under the most ideal conditions, *you are still a brain in a vat.* Only instead of a "vat," we just call it a "skull." You cannot solve the problem of skepticism because it cannot be solved. Sense data is all there is, and the problem doesn't go away, no matter what you do. Ergo, synthetic knowledge about the external world is impossible to obtain with any kind of perfect certainty. Just embrace it already and move on.

Descartes also said "I think, therefore I am" which I believe was the only thing he ever took for knowledge. Thus, reality must, in whatever shape, color or form, exist.butterfly or not.

He actually never said that. He said in two difference sentences the statements "I am", which he then concluded in the bodily sense (in the next sentence) "I exist". The later coming discussion used s the famous phrase we know it now days "Cogito ergo sum" which is a short version of Descartes' argument.

Once, maybe 20 years ago, I had taken a substantial amount of LSD and had been riding my bike around the city for some time. This was before the day of cell phones and I didn't have a watch so I decided to find out what time it was by going to a building that had been known to me to have a clock. When I arrived there, I saw the markings for the clock but I couldn't see the hands. I spent a good bit of time looking at the clock and trying to figure out whether the hands really weren't there or whether I wasn't seeing them because of the LSD I had taken. I had a total existential crisis but, essentially, that is what LSD is for.

[@rogercarroll2551]

As in a different time zone, for example. Everything is relative, isn't it ?

[@starwall8755]

Well, yes, but raising those questions generally require more assumptions. In the evil genius scenario, I must come to accept that such a powerful machine could be controlled by an abstract sentience just to manipulate me, and in the super-computer scenario I must assume that the entirety of the universe is a simulation and that my brain is in a vat experiencing a rendered universe. In nearly all of these cases, it requires more belief to come to the conclusion that my brain is indeed in a vat, whereas it requires not nearly as many assumptions and beliefs to believe that I am a human brain residing in a human body in a seemingly physical world. Also, why is the brain in a vat the "bad case". The brain in the vat's existence could be safer than in the good case. And even if one were to go further, and suggest that you and I and everybody else is also simulated, and that all of our experiences and consciousness and physical reality are virtual, then what makes that experience any less valid than the current reality we experience. Why is the "Matrix" scenario so bad? Even if we were to somehow "wake up" in the reality which houses the supercomputer which simulates all of human experience, who is to say that this other reality is any more real? Couldn't it, too, be housed in a supercomputer? What if our universe is a hologram on a black hole that exists in some other universe? Does that make this cosmos any less real? Why is a natural virtual universe so different from an artificial virtual universe? At some point, we all must stowaway these questions because we do not have enough information to prove or disprove any of it, but instead, we must simply choose the most likely realities and use those as a standard model. I won't believe that the universe came into existence at the time this video claims to have been uploaded because that would require the assumptions that all of the universe, fossils, all of my memories, and so on, all randomly came into existence several hours ago. These assumptions are more elaborate and unlikely explanations for the universe, and simply require more assumptions than for me to just accept the standard model as a most likely reality. A true skeptic would scoff, and dismiss this under the pretenses that we still can't know that the standard model isn't somehow a fabrication, and although this is true, I still think it is a likelihood that I would rather not concern myself with.

[@algot34]

+Zachary Katko We can't prove that we're not in a vat, and they can't prove that we are in a vat, so the whole discussion feels pointless. It's the same story with religion, what if there is a god? - None has enough evidence on either side to prove the other wrong. To battle this we should ask ourselves the question: what is most probable? The most likely theories are the ones that you can scientifically prove and don't require a lot of assumptions. Also, as you pointed out, does it even matter if we're a brain in a vat? Do we truly get smarter by bringing this topic up? I think not. At the end of the day we will still live our lives and experience life in the same manner regardless if we're in a vat or not. Even if we know for certain that we're in a vat, would we really change the way we live our lives?

[@Ansatz66]

+algot34 "We can't prove that we're not in a vat, and they can't prove that we are in a vat, so the whole discussion feels pointless." Who is trying to prove that we are in a vat? Some people may dogmatically insist that we're not in vats, but I've never heard of anyone trying to prove that we are actually in vats. Skeptics are saying exactly what you are: there's no way to know whether we're in vats or not, so the whole question is pointless. It's a recognition that we can always be wrong about almost anything.

[@algot34]

+Ansatz66 I do see that the scepteists are trying to prove that we can never truly be sure about our knowledge. But as I stated in my first comment I don't think that conclusion will do us any good. Even if we can never be sure about anything, we have to stick with what we got, because that's all we have. The discussion is pointless in the sense that we won't get anywhere if we question everything. At some point we just have to let go.

[@Ansatz66]

algot34 "The discussion is pointless in the sense that we won't get anywhere if we question everything." On the contrary, questioning everything is the best way to get places. People are far too trusting by nature in a world where we've been given intuitions that are so often wrong. The whole reason that science has been so productive is it's based on a principle of testing ideas while everyone else is busy trusting whatever they're told. When we examine almost any idea we quickly discover that it could be wrong. The only alternative is to not examine our ideas, and that is the road of credulity and ignorance. Credulity and ignorance won't get us anywhere.

[@algot34]

+Ansatz66 You're right in the regard that we can only grow by challenging ourselves and our reality. However, questioning that of which can't be answered is not efficient for our development. Relying on our experiences and scientific methods is something that I'd much rather be doing than scientifically unsupported skeptic thought experiments.

Cletus Kassady Yes, I fully understand and appreciate the " problem" of hard solipsism (thank you very much) - but, I was just poking a bit of fun at the particular way that they initially framed that little philosophical chestnut. All I was getting at was that there is (or at least: should be) a rather large difference in the anwer you arrive at when you ask yourself the question: "Am I dreaming?" while actually awake as opposed to asking the same while in the midst of a dream. If you doubt me, get in the habit of asking that question on a regular basis - the likelihood that you will ask it of yourself while dreaming will increase appreciably, and you just might find yourself rather impressed at how easy it is to determine which state you happen to be in.

[@someoneonyoutube8622]

***** oh yeah well of course hard solipsism is one thing I mean even there at least one universal truth is accepted and that is "cogito ergo sum" "I think therefore I am" however I'm a hard skeptic I believe that no knowledge is certain even the fact that no knowledge is certain. essentially I just make it my goal to doubt everything even things that appear undoubtable to us such as our own existence we cant actually prove that we even exist much less are dreaming. now that I've finished my little side rant about the differences between radical skepticism and radical solipsism I completely understand what you're saying and given that context it makes sense

This doesn't sound like scepticism, so much as solipsism.

Well…who knows?’ ‘How did he write his poems?’ said Susan. ‘With a brush, of course.’ ‘He didn’t flap around making information-rich patterns in the air or laying eggs on cabbage leaves?’ ‘No one ever mentioned it.’ ‘Then he was probably a man,’ said Susan.

[@someoneonyoutube8622]

thank you someone who understands the difference ;)

[@MelindaGreen]

Perhaps solipsism is simply extreme skepticism, but point well taken.

[@someoneonyoutube8622]

Melinda Green no, no they are not the same things. the difference is that in solipsism you believe that you can't know anything outside oneself but extreme skepticism is the belief that you can't know anything period. the brain in the vat hypothesis is a solipsistic viewpoint because even if your entire world is a simulation it still seems apparent that you exist because you are able to experience the world real or fake so to sum up the atmosphere of solipsism just think of the quote "I think therefore I am" however extreme skeptics such as myself believe that even this cannot be known for sure because there could be some unknown or incomprehensible variable that we don't know that would turn everything and I mean EVERYTHING we think we know on it's head. this means that all knowledge is uncertain including our own existence. so to sum up the mood of extreme skepticism think of the phrase "nothing can be known for certain, even the fact that nothing can be known for certain"

[@MelindaGreen]

Cletus Kassady That sounds like it's bordering on a distinction without a difference. I mean if that difference is meaningful to you, I'll give it to you but I don't see how it matters.

[@someoneonyoutube8622]

Melinda Green the difference is one claims only the self can be known the other says nothing can be known.

[@paulharris3000]

I love this kind of discussion...epistemological queries. I have studied closely many philosophical works,and continue to enjoy some of them.However,from Kant to Whitehead to Wittgenstein I note that the feelings of desire and fear of loss - as reality/ identity markers - are conveniently ignored,as are discussions of the role of consequence in general. Just try convincing a loanshark that the money you owe is a figment of his imagination...My point is that what we perceive in the world around us is best understood as a ubiquitous matrix of consequence - a landscape full of potholes and sudden steep cliffs.The intellectualized skepticism of philosophy,though an entertaining brain tease,will never DIRECTLY help humankind in its day to day struggle.

[@svenk8244]

[@Max10192]

How would one go about proving that we are not a brain in a vat? Can it even be done? If not, then whether we are in a vat or not is completely irrelevant, since a Universe in which I am in a vat and a Universe in which I am not are functionally identical. At some point, the line between illusion and reality just disappears.

I love scepticism, but it should be thought of as ridiculous as a general consensus...

[@ChandravijayAgrawal]

This is best video on skepticism, dissonance and psychology

[@ChrisWarren_as_csw11235]

The math-based part of this is total BS, because math is definitional, not observational. 2+3=5 not because of any intuition or observation, but because of how we define '2', '3', '+', '=', and '5'.

[@joebazooks]

+Chris Warren yet the same is also true of language... whether or not 'blind men can see' is true and or sensible (or 'blind men can see' = 'true' for instance) hinges entirely on how you define the given concepts: 'blind', 'men', 'can', 'see', ('is',) 'true'.

[@ChrisWarren_as_csw11235]

Certainly true of language as a purely symbolic system, but doesn't really hold when one starts mapping language elements to aspects of the world outside language. Math is self-contained - it doesn't have any existence beyond its axioms.

[@joebazooks]

Chris Warren you want to elaborate on what you mean by "[it] doesn't really hold when one starts mapping language elements to aspects of the world outside language"? there is very little difference--so little difference that the difference is insignificant--between mathematics and written/spoken languages.

[@ChrisWarren_as_csw11235]

Language is inherently external to an entity - it references and/or communicates with things other than the entity. Math is purely internal - it has no connection to anything outside the entity.

[@joebazooks]

Chris Warren "language is external to an entity", what does that mean?!?!!! i'm going to assume i understand what that statement means, and even so it's still false. people communicate with themselves, in their head, with the use of language. there in fact aren't things such as unicorns and dragons that are "external to an entity" in the physical world.

[@hewhogoesni8949]

This video is comprised of questions that I raised for myself when I was 10 and discounted as pointless...

[@momenakod6399]

There is a case that has always kept me thinking. It relates to the hypotheses presented in this video about the uncertainty in knowledge. If you have a yellow ball, and you ask your friend what color the ball is, of course, your friend's answer will be yellow. But what makes you certain that your friend observes yellow the same way you do? In other words, what proof dismisses the fact that every brain there is observes yellow differently and just calls it yellow? In general, I think philosophy naturally tries to dodge the existence of reality through basing the concepts of all it's theories and paradoxes on the brain, which is only an obseving machine, it by no means qualifies to give definitive proof for anything. The brain is limited, and here's how this can affect misconception of reality. If you imagine a universe big enough to be considered limitless, your brain must create boundaries to determine right and wrong, the brain can't perceive or understand limitlessness. Here's the catch, if one brain decides to draw a square that positions earth at the top left corner, and another brain positions earth at the lower right corner, then where is earth really? The answer is earth is where earth is, until we decide to put squares around, until awareness and consciousness observes it. And this is why the brain is not reliable to tell actual right from actual wrong, I believe only God is.

[@masterbonzala]

I would like to argue that axiomatic conclusions such as 2 + 3 = 5 cannot be doubted, as they are reached by reasoning and reasoning alone.

[@ffederel]

"Men educated in [the critical habit of thoughts] are slow to believe. They can hold things as possible or probable in all degrees, without certainty and without pain. They can wait for evidence and weigh evidence, uninfluenced by the emphasis or confidence with which assertions are made on one side or the other. They can resist appeals to their dearest prejudices and all kinds of cajolery. Education in the critical faculty is the only education of which it can be truly said that it makes good citizens.” ― William Graham Sumner

The darkness means you do not consciously remember the hard object being there, but your subconscious mind does. Wait... that didn't break down either.....hmmmmmm....

[@andrewpope799]

The video fails to include the potential for the dream/scientist/computer to alter thoughts, which, as far as we know, could happen. For example, the computer could potentially force you to miscount the number of sides on a square. It could also trick you by replacing the thought of the thing that you perceive with that of something else (eg. I perceive my computer, but how do I know that the thing I'm perceiving is actually a computer).

[@michaelmoody935]

I’m still waiting to hear what the asserted “problem” is. Btw do you have a better way of analyzing data?

[@bellza738]

this video is gaslighting me

[@AtSwimTwoBricks]

This is fine as a brief overview of Cartesian skepticism, how the questions it raises about certainty can be leveraged into questions about knowledge generally. But even then I think it needs an additional clear reminder at the end for those (no doubt very numerous) people who would just ask "Wait, why do I care about certainty? Give that up. Problem solved." There are other ancient _direct_ arguments for skepticism that don't rely on any intermediate failure to achieve certainty. The 'Problem of the Criterion', for example, purports to show that any attempt to ground knowledge must either beg the question or argue in a circle. It's a more fundamental problem (other skeptical worries in epistemology and other fields can be argued are just special cases) and isn't subject to the easy "Don't worry about certainty" reply.

[@NioXoiN]

the thing about the dream, vate, and evil scenario is that you still know truths about the world you've been fooled into being a part of. so i can say that without a doubt that where i'm at, whether i'm in bed or hooked up to a computer, i am typing this paragraph.

actually no... you dont get it bush. The video argues that there is "true knowledge" as in knowledge that is universal and part of actual reality. For example, in reality, you are a brain in a vat. However i argue that this definition of "knowledge" is, is incorrect to begin with. I define knowledge as whatever you make it, and is thus rather more flexible. This is simply due to the logical reasoning that its the only form of "knowledge" that matters. Because its the only form of knowledge that you "know". Therefore knowledge should rather be defined as whatever you "know", whether it is part of universal knowledge or not. Therefore even if a brain is in a vat and has simulated hands, the brains "knowledge" is that it has hands.

[@someoneonyoutube8622]

+darthjefory actually I think you're confusing the definition of knowledge with belief because by your definition of knowledge someone can know that a God exists without any evidence

[@MelindaGreen]

Cletus Kassady All things "known" are beliefs but they vary in certainty. Knowledge is information organized, and some knowledge is simply wrong. IE information poorly organized.

[@someoneonyoutube8622]

I mean I believe that a god exists but I cannot KNOW that a god exists just like we all can believe everything is real we can never KNOW that

[@MelindaGreen]

Cletus Kassady Absolute and correct certainty is not the definition of knowledge. Look it up.

[@johnstrax899]

Now imagine that the computer supplying your body and brain with sensory input is actually your brain... Which it is, and that it can be imperfect, which it is. Other than that I always wonder at the energy some philosophers put into this question which, by definition, cannot be answered and yet is not really contested by anyone. I would love to see philosophical videos on the actual real world applications of the debate, such as the implications for jury trials in much less extreme instances than the ones given.

[@Shangori]

Silly question: where is the problem? Really, cause I don't see it. Absolute knowledge ain't possible. I don't think for a moment that we can be sure about anything. But that doesn't mean that we have no possibility of acting upon our experiences. The hand in front of me might not exist, it might be a dream construct, a construct inserted by a computer, or anything else, but I am more sure that I will experience something not pleasant if I put my hand into a meat grinder, then I am that it will give me an orgasm. Even if I would not *actually* lose my hand, I would still experience it as such. And seeing those experiences seem to come forth from the patterns we have concluded from past experiences, we can still be more sure about an outcome than not. That is still the case if those experiences are influenced by a mad genius, are inserted by a computer or from me being inside a dream.

[@Shangori]

Chip Kempston _"Are you absolutely certain of that?"_ I see what you did there ;-) (and I completely failed to see it myself, sheesh) No, I am not absolutely certain about that. I am reasonably certain based on the collective experience of myself and humanity as a whole (altho I'm definitely not arrogant enough to say I know all experiences of humanity :-P)

[@Shangori]

Chip Kempston I agree

[@Shangori]

***** Either way, I don't understand why what is stated here is an actual problem.

[@Shangori]

***** To be honest, it still doesn't sound like an actual problem. I don't see doubt as a problem, even if it would mean doubting literally everything (excluding axiomatic assertions) But I'll keep these in mind. Was planning on buying some of these books anyway.

[@gotinogaden]

+Shangori But, surely, the "I"'s that you are using (especially in your original comment) must hint at something undubitable, like a _subject_ that actually exists in order to experience all those illusions and dreams you mentioned. It is hard solip... err... hard to believe that one can still doubt even his own existence. Well, after Descartes at least.

[@s71402san]

That's why skepticism is best if applied to a certain scope and not to everything. Even then, the results are still worth to be questioned and tested again, since life itself is a big test.

[@ProfessorBorax]

I don't see why this is a problem.

[@mikaeljensen4399]

Scepticism is not the negation of knowledge. It is simply the statement that absolute truth is not achievable.

[@thevisi0naryy]

Knowledge is not more important than having a valid reason to believe in something.

[@IGEKT]

So it's belief afterall. Not absolute certainty

[@BasementcatsBFF]

I feel like the people in the comments who don't see a problem or who argue that the knowledge we have is "good enough" are the same as the math students who ask "but when am i ever going to use this" The answer is, as always, probably never but that doesn't mean the ideas aren't important. For example: I see a lot of people who describe themselves as Skeptics. This video is about what happens when you take skepticism to the extreme. Everything kind of breaks down and you end up not knowing anything. It means you can't have an ideology based entirely around skepticism, you have to draw the line somewhere and just accept the information coming to you. That's important for people to know. They can then ask themselves just where they draw that line and learn more about how they view the world as opposed to someone else. (or not, you could totally integrate complete skepticism into your worldview but chances are you don't and believe things like reality is real)

[@Stew282]

The brain-in-a-jar type hypotheses are untestable and unfalsifiable. Thus they are a pointless waste of time other than a bit of pondering when you first encounter them.

[@AbruptAvalanche]

Welcome to philosophy. This isn't science we're talking about here. The unfalsifiable part of it is actually the key to the skeptic's argument. You CAN'T prove otherwise, so how can you really know?

[@Stew282]

Adam X It's an interesting idea when you first come across it, but after a bit of thought it becomes obvious that there's no way of knowing, so it's completely pointless to consider in any serious context.

[@AbruptAvalanche]

"...but after a bit of thought it becomes obvious that there's no way of knowing..." This is exactly why the skeptics bring up the argument though. Since you cannot know that you're not in a jar, can you really know anything for sure? They argue that you can reasonably doubt any belief you hold, therefore you don't really "know" anything. Now, if you don't care about epistemology at all, then you're free to run along and call it all a pointless waste of time. I was assuming you cared about philosophy though, at least a little bit, due to the fact that you clicked on the video.

[@Shadeius]

That's the difference between science and philosophy; science studies the world while philosophy studies ideas. Even if you may not think it; the brain-in-a-jar hypotheses is an important one because it can create basis how a person thinks about the world. This may seem to stupid to somebody whom completely trusts in empirical information (like you if I'm not entirely mistaken) but it's just how it is because every person has their own way of looking at the world. For example I believe that a human can never know anything simply because a human cannot gain objective information about the world. While it may not be important for my everyday life it does shape how I think about the world as a whole in very fundamental level and forms basis to my every assumption about the world.

[@Stew282]

Adam X I care deeply about truth. The universe is a fascinating place, full of wonder and mystery, and we are on a journey of discovery. Knowledge, such as it is, has increased exponentially over the last few centuries. Never have we known so much as we do now; and in all likelihood, what we know now will appear infantile to our descendants. No, we can never "know" anything with absolute certainty. Absolute knowledge only exists in mythology and has no relevance to reality; but in our imperfect world, knowing sufficiently to advance human experience is good enough, and is the basis of all progress. Epistemology is not about the mental onanism of "thought for thought's sake" it is about how we use logic and reason to increase our knowledge of the universe in which we find ourselves. If you want to waste your life pondering the unfalsifiable, that's your prerogative; but you will achieve nothing in so doing, and advance human knowledge not a jot.

[@dianakirby4303]

No amount of arguments against this knowledge can persuade me against my conviction. And behold! I am right, and I know I am right. There you sit, reading my comment -- conforming the reality of my waking life. Reality is coherent and shared. Skepticism is healthy in small doses... It is important to question your beliefs. But "sapere aude!" my brothers and sisters! We do know a thing or two - some of us many things. Even controversial matters, have pretty clear cut answers, which it is possible to arrive at with honestly and reasoning. There is no god, no after life and you are not a brain in a vat!

[@BuzzyBe]

The point of the video is that you should ( when you are able to ) be aware of how the world is presented to you and that in fact, everything you know; or think to know; can be generated by an external source. Telling us how important it is to always ALWAYS try and find different points of view.

[@the7thage576]

Wtf. Dreaming and being awake are two completely different t experiences

[@juh0e]

Well, yes and no. You do always wake up from dreams (at least we assume this), allowing yourself to compare it to the awake-state (thus, coming up with many differences I guess). But this is only possible if you wake up, which is the skeptical question you should not have an answer for.

[@YountFilm]

Critiquing "I think therefore 'I' am": what reason do you have for believing that the deed-that of thinking-requires an "existing" subject in order to take place, the subject "I"? A redaction of the phrase to eliminate mendacity: "Thinking happens". "There is no do-er behind the deed"... "The doer is merely a fiction added to the deed; the deed is everything". Deconstructing solipsism. (See Nietzsche's response to desCartes in Beyond Good and Evil)

[@Tomcat82]

This definition of knowledge is silly. What if my whole life is just a dream? What if we're all plugged into the Matrix? What if monkeys fly out of my butt? What if God is real? What if any number of alternate realities are the case and I am not only blind to them, but am experiencing a false reality, as well? (None of these follow Occam's razor, btw) If your definition of knowledge is one requires absolute certainty, then fine, I concede that it's impossible to know anything. But that approach is not helpful when applied to real life, and thus is totally useless. This definition of knowledge has no meaning. Another definition of knowledge, one that requires demonstrable evidence rather than 100% absolute certainty and allows for improvement (such as the scientific method), has shown to be much more useful to us. Following the evidence will always be more likely to lead us to the correct answer, even if we can't know with 100% absolute certainty that we've actually arrived there.

[@someoneonyoutube8622]

ok so even though you cant know that evidence exists you still believe that it is a reliable source of information and are willing to follow it down the rabbit hole? that makes perfect sense have fun with being potentially wrong ;)

[@Tomcat82]

+Cletus Kassady Interesting. So can you truthfully say that you actually believe in your own position? I highly doubt it, and I'll prove it. I'm going to go out on a limb here and assume you regularly participate in most or all of the following things; You go to work. You pay taxes and bills. You maintain hygiene. You obey rules and laws. You adhere to social norms. You believe your parents are your parents (and not imposters/robots/aliens/etc). You maintain relationships with friends/family. You mourn the death of loved ones. You care about certain political issues and current events. You assumed I exist by responding to my comment with your own opinion...using a device that was developed using science, which outwardly rejects the notion that absolute certainty is necessary to advance our knowledge and understanding of the world and universe. (continued in next comment...)

[@Tomcat82]

+Cletus Kassady (...continued) You do all the things that inherently and necessarily requires the assumption that your perceived reality really is as it seems, and that your actions have predictable consequences. If, as you suggested, you truly cannot trust your own experience of reality with any degree of certainty, then why conform to the inconvenience of work and responsibilities? Why not just do only the things you want? If every conceivable scenario of reality is as equally likely to be the one true reality as the reality you experience (remember, you can't know anything and any evidence means nothing), then you can't trust friends or family. They could just as likely be robots or aliens or the matrix or figments of your imagination. They could just as likely be plotting to kill you as plotting how to celebrate your next birthday. Who can say? It's 50/50, right? Why take that chance of even continuing to associate with them? Your life is in danger! Run!

[@Tomcat82]

+Cletus Kassady Cletus, the only rabbit hole around here is the one labeled 'Solipsism," and you're standing right in it. When you argue that a scenario supported by zero evidence carries just as much weight as one that's strongly backed by demonstrable evidence, you're on the wrong side of that argument.

[@someoneonyoutube8622]

Thomas Catlin haha oh this Is going to be fun I can tell you believe your position very stubbornly. First of all I'm not a solipsist I'm a radical skeptic so I am as far beyond solipsism as it is beyond you and clinging on to evidence as a lifeline even though it's sinking with you isn't going to help you any because my entire position is not built around something as unreliable and flaky as evidence my entire position is built around doubt. I am not confined to the realm of "this is this because it is that way" as you are so I don't need to prove anything nor is it my objective to prove anything it is my objective to doubt everything and therefore put the burden of proof upon you to show that evidence and by extension knowledge and everything else even exist.

[@efracb]

Not the type of skepticism that I expected, this kind doubts of absolutely everything, and there's no point on doing that, on the other hand, skepticism has led to the most amazing scientific discoveries, that's the kind of skepticism I expected to be analyzed

[@mm-rj3vo]

I've always found that skepticism doesn't break down at the level of dreams. For dreams, in my opinion, are a form of temporary insanity and belief, but not knowledge. I've also found that even the most vivid and lucid dreams do not have the same quality as waking consciousness.

[@mariodeleon7869]

I am so happy to elucidate that dreams are my salvation; becouse when I dream, am beyond lucidity, in fact they are better than awakened reality. They go beyond my level of understanding in this parallel life.

[@starfishsystems]

Hmm. I understood that skepticism is a method used to ensure an explicit (and warranted) basis for beliefs. I wasn't aware that it attempted to develop a basis for knowledge. But perhaps earlier forms of skepticism were more ambitious, and that's what's being claimed here. I think that one of the challenges in making a video of this kind is that it's difficult to differentiate between where the viewer is being motivated, and being shown the history of philosophy, and being presented with a formal argument.

This was a very interesting topic. Because it brings up the question of doubt. The primary doubt that any thing really exists that it could be a construct of some external force or an internal force. My personal experience will tell me that I can rule out the Dream Theory because my dreams rarely ever have me doing what I do on a day to day basis. If it ever did, it was me reliving a specific event in my life. When it comes to watching videos or playing video games I have never dreamed of those events, I was always placed in the game acting out what the character would do but with the loss of the super ability to do it or only half of the super ability. With the other tow arguments I really don't have an answer, because they could be true or it could be our minds playing tricks on us. When we start to over think what is real and what is not we tend to make up theories about what could distort reality. I am pretty sure the dream theory game up because that is all we knew and as we developed the technology or the concept of those technologies that could enslave our minds. With these type of theories out there we would question our very existence its self. Non the less these topics will and should be discuss because it is always good to explore rich and deep ideas such as these.

There is an equivocation that the skeptic makes...they are slippery. They conflate not being able to demonstrate how you know something with not knowing that you know something. Just because you don't know how you know, it doesn't mean that you don't know that you know. And just because you can't demonstrate or put to words how you know something, it doesn't mean that you don't know how you know.
