What is truth? What is knowing?

Truth and knowing.

Quote:"What is truth?" — Pontius Pilate, the Gospel of John.


Truth is easy to explain but rather harder to understand. why? Because in its explanation we are trying to form a true statement about what it is to form a true statement. This leads to confusion, and unfortunately to the rejection of what is true truth (so to speak) and the clinging onto those rocks that we do understand (usually what is called scientific truth or religious truth - i plan to show there is no such thing).

Knowledge on the other hand is not easy to explain. To know something one has to belief it is true and have that knowledge accord with something (usually ones perception of reality). Knowledge is also distinct from mere information. In that both concern a truth but knowledge has a purpose or use. It is also usually a learned experience.

So here we have our parameters of investigation. In answering the following questions and drawing the threads of their answers together under a general philosophical theory I hope to cast light into the darkness, or at least classify the dark better.

The questions are:

Are there really different types of truth?
What does it mean to know something, as opposed to just believing it?
Can we really know something is true?

These are of course Titanic questions that Philosophers and Scientists have struggled to answer for generations. A cop out here would be to just fill this post with quotes and analysis of other thinkers works, but i prefer to actually try and think of some answers myself in my admittedly limited capacity to do so.

Quote:"Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth." — Sherlock Holmes (Sir Arthur Conan Doyle)


“I am” is taken as the most fundamental truth of all. But why? Simply because it is the easiest to prove. One can prove “i am” every single time one thinks it and by thinking it one can simply and clearly assert it and by proxy reject it's negation; “i am not”. Once we have made an assertion that we are clear is true, we believe it. This proposition is now added to the pool of positive propositions, or what i call ideas. This pools of ideas are like bricks building a house. The most simple ideas are the foundation upon which are placed more and more ideas forming a wall. The walls of this house are held up by the simple truths of the provable simple ideas.

So what is a simple idea? Take the following:

I have a rock 0

This idea is simple. Its truth directly relates and relies on the fact it calls in place. I actually have a rock. I perceive that in my hand is a rock. This perception is so solid and consistent that I believe the statement is true because I can prove it in a millisecond by referring to my perception of the object in my hand. As long as that perception remains true, the idea is also true.

Our minds perceive reality all the time through the senses and the beliefs that this perception give rise to are what we take as true.

So, for me truth is a belief in the mental linking of a simple idea to a perception of reality. So, where is the problem with truth? The problem comes with compound ideas:

Say I have a rock 0

And I add another rock 00

Now I call into place a compound idea and, in the form of a special language (maths) that I have learned, i say that i have two rocks. I perceive the rocks in my hand. I say to myself “I have a rock” and “I have a rock”. That means I have two rocks. This is a compound idea, and idea based on language. In this case the language is mathematics.

Mathematics is a shared language with formal rules. I learned mathematical language at school by the teacher communicating the idea, the conceptual idea, of “two” to me. Once I have the idea embedded deep withing my mind, I cannot look at the two rocks without referring to them in this way. The concept “two” is not to be found in the rocks themselves and it doesn't require i directly refer to reality. It is an idea over and beyond the rocks perceptions and a total construct of humanity. The wonderful thing about mathematical ideas is that because they are a special language they can operate on other concepts and ideas contained within their language. They are a special language because humanity has formulated rigid rules for the linking and further compounding, as well as the operation of these ideas and the creation of further rules and mathematical language.

The operation of this language takes place only in the mind. It manipulates ideas formulated by its rules and operates to produce results upon which we can (if we should need to) refer back all the way to the simple compound idea that we can perceive to correspond to reality. I have a rock.

I have said it before but I will say it again: The communication of ideas is the primary accomplishment of mankind. This combined with the formalisation of mathematics has given mankind a startlingly powerful tool for both the communication and operation of ideas.

So what is the problem here? The problems are that for all it predictive abilities mathematical propositions are only perceived to be true. This is very hard to spot in the simple arena because the operation of math is so fast in our brains and it can always reduce to a simple perception of reality such as “I have a rock”. However, it is the case that at very high levels mathematicians themselves only talk about models. Models are math that is so complex or cutting edge that the reduction to a simple truth is not yet possible*. Mathematicians try and construct math ideas to explain their predictions or perceptions but we cannot actually call them true yet or even at all. Math models depend on variables and mostly what is called a priori variables (or what i would call the communicated shared idea independent of a perception of reality, as i don't think a priori ideas exist. But then that is no where near as cool as saying “a priori” and i need to find a single word for it, preferably one in Greek!). The modeler tweaks the math until it “fits” or describes his perceptions of what is happening empirically.

This shows a very important thing. Math does not operate on reality only on our perception of reality and some math cannot and will not progress beyond models because the perception of reality is false. Mathematics is inherently incomplete and can involve paradoxes such as:

Quote:Will Rogers phenomenon is the apparent paradox obtained when moving an element from one set to another set raises the average values of both sets. One real-world example of the Will Rogers phenomenon is seen in the medical concept of stage migration. In medical stage migration, improved detection of illness leads to the movement of people from the set of healthy people to the set of unhealthy people. Because these people are not healthy, removing them from the set of healthy people increases the average lifespan of the healthy group. Likewise, the migrated people are more healthy than the people already in the unhealthy set, so adding them raises the average lifespan of the group.

WIKI

The Mathematical language is not complete and not fully reliable. One has to question whether it ever will be.

Math is not then a different type of truth, only a means of operating on ideas which has the ability to be reduced back to a simple idea. Simple ideas, remember, being linked directly to perception of reality via positive propositions. Also remember that because we are talking about actual truth, reliability doesn't enter into it, since all truths are true totally.

What else then claims to be higher truth? Logic perhaps. Logic as I define it is the operation of reasoning on a proposition to produce a result that is not contradictory. Logic does in no way need to refer to a Simple Idea or to reality. In fact, despite my love for it, it can be “done away with” very simply in the following example:

What I am now saying is false, or meaningless.

This follows but cannot be true as that would prove it was false. Basically the problem is that because the rules of logic allow for self referencing one can construct propositions that cannot be successfully proved one way or the other. Logic is another language like math (very like in fact since one begat the other), but unlike math its formal rules are based not on new Independent Compound Ideas but on less reliable perceptions of General Compound Ideas such as those used in English. So, like math logic is not always true. Logic suffers something that math does not. It can operate on ideas that do not reduce to perceptions of reality. Logic isn't a type of truth at all and I think it is a misuse of the idea “truth” to mix it up with Logic.

What of faith then? Can that be true? Here we come into the second of my original questions, regarding knowledge. Consider this,

The sun rose this morning.

I don't need to have faith that this is true. I was there. I saw the sun rise and experienced the consequences of the rising sun. But can I know that the sun will rise tomorrow? The sun has always risen. This is a Simple Idea which is perceived relating to reality. Every day the idea has been proved and everyday the idea is strengthened. This strengthening is what is called Custom. It has become customary for man to perceive the rising of the sun everyday. We expect it. We believe it will rise tomorrow as an argument from inference:

The sun has always risen in the morning.
I infer that the sun will rise again tomorrow.

We believe this idea. Until it has happened we cannot prove it one way or the other, but it is a reasonable (to us) inference about our perceptions of the way the world works. This is belief. It is the same as saying “fire is hot”. This is an idea based on the historical data available to us. Fire has always been hot so fire will continue to be hot. We do not know that fire is hot until we check but we believe it will be because it customarily is. However, once the data goes the other way we get confused. Consider the sun again. imagine that today it didn't rise. From this moment on how can i believe that it will ever rise again? The custom has been broken and I can no longer simply rely on a idea being reinforced every day. I need to have faith. Traditionally faith has been seen in this way, as belief in spite of the evidence, but i don't think that it is necessarily so.

A more cogent example. One day the sun will burn out and will not rise. There is no way for me to know when that day is going to happen and it could happen at any time. Since “to know” requires that i check, i cannot know until the event has passed. I believe the sun will rise because it always has, but more than this, because i also believe that one day it will not, it requires faith on my part to believe that the sun will rise tomorrow. Faith is therefore not concerned with truth at all, only belief. It is a kind of hope mixed with (or mired with) a belief (the sun will rise) which in turn is reinforced by momentary knowledge (that moment when the sun does rise) and custom (it has always risen before). Truth only enters this in the moment, that moment when the sun actually is rising, the moment that my idea can be directly related to my perception of reality, in fact the moment that I know.

So my final question “how can i know something is true?”. For me you can only know something at all when you check. The famous question “what do I have in my pocket?” is not just asked of the viewer but also of the questioner for they do not know what is in their pocket until they too check (as, for example, it may have fallen out and they haven't noticed). In checking they validate the idea of what they have in their pocket by the reference to their perception coming to them via the senses. But, until they check in some manner by looking, or opening their pocket they only believe in the idea they have of what is in there. Until they check they do not know. Once they have referenced the idea to their perceptions of reality, then the idea can be said to be known truth until the circumstances change and a fresh check is needed. This may sound pedantic and suggesting only "momentary truth" exists but consider that often only a check with the eyes or even an operation of math (based on Simple Ideas) will constitute a check. Humans do this all the time, millions of times a second, so fast we dont even notice.

It is this that explains science being held as a high truth. Because science is a result of measurement (and a combination of math) it is constantly referencing its ideas to the perceptions of reality. It is the most “grounded” way of producing strong ideas available. It is very careful to remove as many variables as possible and to rely only on observations and their computation.

when it comes down to it, there are no different forms of truth. To say so is to court a misunderstanding of the terms and to ignore the fact that all that is considered true is constantly being reduced to Simple Ideas and referenced with the perceptions of reality.

The question left and rising from this is: What can we take to be reality?

to quote the great Obi-Wan Kenobi "you see it is true, from a certain point of view"

I understand that all is false and nothing can be proved at anything other than at a single moment and that only if I chose to belive my own senses.

Strictly speaking, I am is not irrefutable, as the meaning of 'I' comes under attack if it is impossible to prove the existence of others - see attacks on descartes. 'It is', has been suggested as more steadfast.

Knowledge is generally defined as 'justified true belief', how you can attempt to define knowledge then without a irrefutable definition of truth I don't quite know

It fundamentally comes down to the question of metaphysical or materialist thought. From there up if you disagree on that then you will disagree on every other important issue. For a materialist (in the philosophical sense of course) the question of proof of existence for yourself or for others and the world around you simply is not a question - you can see it, feel, it, hear it, touch it etc.
The metaphysicist however has to deal with the problem that taken to its logical end metaphysics ends with the idea that nothing is real outside of the self and bang, there you are in an egocentric universe were your inability to direct events is a constant disproof that it is you that is the centre and not someone else.
Generally metaphysicists have a harder time of it.

Knowledge is easy to explain: it has an agreed upon definition - a true justified belief.

You claim that "me truth is a belief in the mental linking of a simple idea to a perception of reality" - what if you are mistaken in your perception of having a rock?

Mathematics isn't a language: it is an axiomatic system.

First you claim that mathematics is a language, and then employ the term "mathematical language" which carries the implication that maths is not actually a language - if it were we wouldn't need 'mathematical language' to speak of it.

Mathematics is no more a language than set theory is a language.

You claim that you don't believe a priori ideas exist, but also simultaneously claim that 'I am' is an an idea that we are able to form a priori.

"Logic as I define it is the operation of reasoning on a proposition to produce a result that is not contradictory" - this fails to state that within logic the important factor is that there is a particular structure of operations which constitute valid logic. It also fails to note that the reductio ad absurdem is a totally valid logical operation in order to disprove one of a set of propositions.

Explain to me how logic is a language? It is a set of operations.

Explain to me how one of logic or maths begat the other?

Flawed example when you take a diversion through Hume: even if the sn burns out it wills till rise. The rising of the sun is not based on the illumination it gives us, but rather on factors of celestial orbit and planetary rotation. A parallel counter example: even when the moon is not illuminated by the sun it still rises and sets.

Once again you then state that truth relates only to perceptions or sense data, and not to any actual world that may exist beyond any impressions we may receive, Thus if you perceive one line to be longer than another in an optical illusion, under your definition it is true that that line is longer than the other. Similarly, I may perceive a different line to be longer, having used a ruler to check, and so to me the other line is longer... what was that you were saying about there only being one kind of truth?

Does that mean we cannot know anything if we cannot make others believe it(justify).IMO that "agreed upon definition" means knowledge is a kind of belief which many believe(how many?).

Has anyone you know of attempted to live with the practical consequences of the philosophical idea that nothing is knowable? AKA has any philsopher lived in such a was as though s/he believed that reality may or may not be real? If not I believe that such a philosophy can be discounted on that grounds alone. A philosophy that cannot be lived is just so many words, a waste of breath.
I suggest that if one claims that they truely believe that what we reality may or may not be real, one should live by the implications. I find that such a life would be quite painful unless one allowed previous experience to play a role. For example, one could attempt to walk through walls due to the fact they may or may not exist, and if they could not learn they would run into the same wall every day.

A philosophy that cannot be lived is silly.

No, in this instance 'justified' refers to the grounds upon which we hold a particular belief. The exact definition of what constitutes a justified reason for a belief depends upon the particular epistemological model that you use, but to keep things simple I'll use a fairly basic example: it would be justified to believe that there is water under your land if you drill down and find it, whereas it most likely wouldn't be if you just went dowsing.*

I dont have to find someone,Im AM one.And I can live with what I believe because I do NOT say there is no knowledge,I say there is NO absolute knowledge,only relative ones.I do believe the practical benefits of science,but I do NOT believe that we may prove they are %100 true.I do believe we can ONLY prove ideas based on the axioms(or whatever you call them) and we cannot prove axioms(this is against their definition),which means there are only relative truths.

Your wall example clearly tells me that you do not understand what Im saying.I believe my above arguments contains the necessary answer to it.

This is a facet of the biggest problem in any philosophical system. Before it starts there are certain assumptions made about reality that if disproved would knock down the whole system. This is not a huge problem whist you live within that system but it does mean that it is very easy for opposing ideas to end up in oh yes it is, oh no it isn't arguements. Something we encouter a lot in the political debates on this forum. It is inevitable unless one side is prepared to conceed this basic ground, which is highly unlikely in an adversarial debate.

Indeed, I'm not denying this: the method of justification depends upon the epistemological framework that an individual holds. What is not disputed between the various different serious models of epistemology is the importance that is placed upon the reasons for the belief being justified - there may be many different ways to have justification, but it is still required.

You only say the last because you have not carried materialism to its logical end - that everything that occurs and is sensed is nothing more than an extension of the physical world and physical laws. As such, no strict materialist can direct anything in the world, including themselves as everything -including each individual thought emotion- are a foregone conclusion based on a set of strict, unchanging physical laws, and therefore, conciousness is merely a cruel accident that tricks individual puppets to believing they can choose their own paths or deserve credit/responsibility for anything that happens in the world.

Mathematics isn't a language: it is an axiomatic system.

Mathematics is no more a language than set theory is a language.

All that is true is communication.

Communication of one person’s mental state to another person.

Say I have a rock 0

And I add another rock 00

What is it that tells you that there are two rocks? Where in the rocks is this “truth”? Imagine if you will, that you didn’t know that one rock plus one rock is two rocks. Imagine hearing that for the first time. It is an easy idea to communicate is it not? Two rocks. This is two rocks. I have one rock, add another and I have two rocks. Even as you read these words you know them to be true. Why? Because it is demonstrable and a consistent outcome. It is a customary outcome that you can repeat as long as you want. More importantly though it is now an idea inside you head. A neural connection that will always fire when in the presence of two rocks. It is your ability to communicate this outcome and others to your children that will give them this idea too. We hand over further development to teachers. Teachers of mental ideas. They start off easy. The time. The date. A dog. A cat. Easy ideas that lay a foundation path work in our minds. It makes us receptive to certain ideas. Very receptive in some cases. Mother. Father. These are ideas in our minds only. A shared idea is communication. Essentially personal. We both have mothers, but our surrounding ideas will be different. It is in this way that what we take as true is built up. Our brains can think very fast. Once you have accepted an idea as true, many more ideas can be built upon it like bricks.

000 three rocks
Ten rocks ten rocks


The communication of ideas is the primary accomplishment of mankind.

This is often referred to as languages. These are shared frameworks of ideas that like building block we accept each as true and like Tetris build lines that stand solid together. It doesn’t matter what the language is only that the people both use it to share the ideas, to get the mental picture in my head into yours in the same (or similar way) to how I see it.

Digression – art.

Art is also a communication of ideas. All communication requires at least two people. When I paint something, say the last painting I did of my grandfather. I have an idea of him in my head. I am trying to use the paint to put down that idea on paper. This idea has to be capsulated and fed out through my hand. It is very hard to do. The idea that I have of say a particular day will always sit in my mind until I put it down. To put it on the paper I have to destroy the idea. Why? Because whenever I think of that idea again I will see the painting. The idea is no longer just that day. I have tried to communicate more than just the strokes. I have tried to communicate the “truth” of my idea of my grandfather. It doesn’t need to be measured mathematically. You cannot plot such things on a graph. This is why many artists feel bad about their paintings. They know it can never live up to their mental idea and now it has been forever altered. They take reassurance from the fact that the painting perhaps communicates it to others, but it is a price many artists cannot take.

It is for all that a language. It speaks to you in ideas, you just have to listen. Experimentation in this field has unfortunately led to the creation of meaningless art that the view imposes their own ideas upon, it has no idea of its own that it is speaking. This is a pity.

/end digression

The horrible truth. The horrible truth isn’t taught in schools. It isn’t taught by many parents and it certainly isn’t taught by our leaders. It is this:

There is no such thing as a triangle.

Should man all die tomorrow. There will be no more triangles. Our ideas die with us. (So many original thoughts that everyone has all the time. If only one could write them down man would be living in the stars by now). A triangle is our idea only. It is a shared idea that we have about the universe and the way it works. One may use it to manipulate other ideas. One many even communicate it using language or the results of its mental manipulation, but this doesn’t change the fact that it is only an idea.

To use the rocks analogy. There is nothing in the rocks that contains the word “rocks” or the idea that that word communicates. When the idea dies with us, the rocks no longer have that name. They go back to the darkness. The idea of a rock is entirely in our perception, not with in the rock itself. And more importantly, the use of the idea (or word) rocks is also within our perception.

So it holds for math. We use the language of math to carve out our ideas about the universe. Such things can be logically proven, such as quarks that have never even been seen. Scientists call this prediction. A logical proposition that has no verifiable conclusion.

In ethics, we are dealing with so many ideas that it becomes impossible to agree on them. The communication of the idea is given over to Lawyers, who use their mental building blocks (that they developed in law school) to re communicate the idea along an agreed legal language. A framework that is agreed upon. Why else would what is legal in one country be illegal in another?

It is all perception my friend, all of it. There is nothing else.

You claim that you don't believe a priori ideas exist, but also simultaneously claim that 'I am' is an an idea that we are able to form a priori.

Actually what i said is : “I am” is taken as the most fundamental truth of all.

Is taken. Im trying to show why it is taken as the most fundimental truth of all. I am not, and neither is my writing, claiming it is a priori.

Explain to me how one of logic or maths begat the other? See Euclid's Elements. Before that math had none of the forms it has now.

Flawed example when you take a diversion through Hume: even if the sn burns out it wills till rise. The rising of the sun is not based on the illumination it gives us, but rather on factors of celestial orbit and planetary rotation. A parallel counter example: even when the moon is not illuminated by the sun it still rises and sets.

Ok I agree the rising of the sun isn't a strong example, its just a nice easy one.

So, consider:

Premise 1. Outcome A happens every time I do action B.
Premise 2. I have performed action B a million times and every time I perform B I see outcome A.

It is fair to assume, to infer, that the next time I perform action B that again I will get outcome A because the historical data shows this is what occured before (custom).

I therefore believe that B causes A. It is a belief. Probably a good belief to have since I have a million checks that all came up trumps.

However! And its a big however, I can only know that the proposition:

B causes A

...by checking. Otherwise how can I be sure that the custom continues? Imagine that randomly, once in a billion times:

B causes C

How can I possibly know that A will follow from B this time? Only by checking.

Knowledge is based on experience. I can only have experience of an outcome that I have performed. I can hardly have experience of an outcome before I perform it can I? I can only infer from previous outcomes and trust (believe) that B will cause A this time.

Imagine that I hadn't performed B before. I only have a book written in badly translated Japanese that when they performed B that they saw A's. Could I be said to know B causes A? No, of course not.

I fully realise that it may not appear this way to us humans. How many million checks do we perform every second? hundreds. Every moment I confirm Gravity, every moment I confirm that I need oxygen to survive, and every moment I see that my perceptions of time are continuing. Turning to the "sun rising" example again, people might object that we have all sorts of peripheral checks being made all the time that surrounds the actual physical check on the rising of the sun. such things as mathematical knowing regarding gravity, orbits, atomic decay. Realistic checks such as simply checking to see the sun is still there, that we move around it, etc. All of these myriad checks are a worthy and beneficial thing to inferring with utmost confidence that the sun will come up:

that B causes A.

But you don't know until it has.

This may seem nit picking and pedantic, but it goes to the heart of a lot of matters and is, I think, the building block to a stronger understanding and therefore a more able creative mental view point down the road.

Still, believe it or not. That is up to you. Belief is after all inference.

Once again you then state that truth relates only to perceptions or sense data, and not to any actual world that may exist beyond any impressions we may receive

Objective truth? well, name me one. Objective as in its not a human idea or language. You perhaps may say, "the world exists". To which I would say, 1. You perceive the world exists. 2. Your perception is being checked constantly by your brain.

Perception is often wrong. As is checking. For example the other morning i woke at 6am and got up. I could feel my body waking, i could also feel my mind checking whether i had enough sleep and how tired i still was. I went into the kitchen, made some toast, put on the tea pot, sat down and looked at the clock.... 3am. for a second i couldn't believe it. 3am. I had been asleep only an hour and a half. With a moan i went back to bed.

If someone had asked me, on the way to the kitchen, what time it was, i would have said 6am. I even could have mentioned "evidence" that i had that it was 6am, but I was wrong. Ideas can be wrong simply because when it comes down to it, they rely on the checking of a simple idea (the time) against perceived reality. If you perceive reality incorrectly, then what you "think" you know will also be wrong. I reject nothing, i rely on nothing. Memory too is often wrong and distorted.

The way we check the Simple Idea against perceived reality with the sun is by looking at it.

I imagine this as two lines stretching off into the distance. One is reality, the other is our perceptions. most of the time we can keep the line parallel by checking our Simple Ideas to the perception of the line. But, for many reasons often the lines are not. Some peoples reality lines are so far out of sync to be dangerous. EPIII Scientologists for example or Nazi's.

Any ideas about the past, future are no longer known if you cannot check the fundamental realities in some way. For example, I may have visited a black hole and taken measurements of its strength, and when I got home might say "the black hole is this strength" but i shouldn't. I should only say "when i measured it the black hole was this strength". The current strength of the black hole is unknown.

Man combats this by checking over time and using the rule set of math to produce averages over a period of checks. Then we look for trends and populate graphs of data. Finally the scientists can say "The average strength of the black hole is so and so". This is communicated via the human terms of the language of math and is believed. But then average is a human idea and the operation of math is fixed, so to say the average of something is to reduce the possibilities of flawed perception to a manageable level. Errors should only rise in the checking that went into producing the data.

That corny saying "trust your feelings"

We got words, we got facts, and we got nothing. No signs, no promises, no certain things, nothing that we can take for granted. So we can only go forward, and hope for the best.

Knowledge is easy to explain: it has an agreed upon definition - a true justified belief.

with a few minor gettier induced kinks to work out - but those probably reduce to questions of justification anyway.

You people have too much time on your hands. I'll admit that in my spare time I sometimes ponder philosophical questions, but they don't really accomplish anything! Once you find the answer to your question, what can that answer be used for? Think about the philosophy of philosophy for a bit. And then do something more meaningful and constructive, and save the philosophy for a rainy day or broken leg.

Of course, that's my opinion, which, from my point of view is truth, but to most others here my opinion is probably as meaningless as your philosophy. And, since I can only prove truth to myself, I'm probably wasting my time.

Well i do have a degree in the subject, so i tend to think this way anyway. To me, sitting on the tube just reading the Sun newspaper is wasting your life.

This understanding leads to much greater things. In the second part of this post (coming next week) I will show why this understanding explains much that is considered unknown.

so there! :D
