I shall write down some thoughts I had regarding the concept of truth, perhaps mostly the question what is truth. It may turn into kind of a rabble.
The problem is that we are tempted to create categorical thinking. Then we are tempted to believe that these categories are universal truths. And most of our words where we usually get the concept of truth involved are usually just used to describe specific patterns, correlations or sequences. Chair and war draw vague lines. Everyone has a general idea of what war is and what a chair is, but the specific details in the definition can always be discussed making it hard for me to believe that there actually is any real truth in them. I just see them as an attempt to describe a specific pattern, correlation or sequence, and this specific pattern correlation or sequence did not have "intentions" in any way to be true, they just are, without any concept of truth that it can adjust itself into. So because we describe a specific pattern of molecules as a chair, does not make "Chair" a truth, it is still no more than our attempt to categorize this pattern making chair no more than a category not a truth. Also I believe the same can be said about war, it is just used to describe specific patterns, relations or events, that are not really true, making war a category not a truth. I will go as far as saying that 1+1=2 is not truth. As the concept of one is just category. Well one is the glyph/symbol 1(that can draw vague lines if drawn bad). But if one is just a glyph/symbol how is it logical that if you add two 1s together you get 2. So one is clearly used to describe something more than just 1. And now is when it really start drawing vague lines as you can't really be sure on what one is. If you say that one is an atom, it will be like atom + atom = atoms. But then will a molecule contain many Ones, or can a molecule also be one? As it is impossible to say what one truly is I don't really think that 1+1=2 as both the concept of 1 and 2 are just categories we have invented in a logical system we created, not truths. I believe I will say this about truth itself, that it is just humanly invented for it's great convenience not that it really is "true".
But also an interesting thought I had is that animals may see the world as more true than humans. Because when we humans see a chair we can think that it is a chair immediately placing it in a category, and categories are not truths(In my opinion). While a cat as I think just see what he sees, he does not see a chair just what he sees(Making the cat see truth much more than what is normal for humans). So really I think that if you think that it is true that it is a chair when you look at a chair, I think is not really true. But if you look at a "chair" and see it as nothing more than what you see. So in a way; What I see is what I see, nothing more. Then I think you are closer to the "truth" in a way, altho I think that even truth can't be true as it is just a category like for example a chair or a war. So the bigger truth is (in my opinion) is that if you see a "chair", it is more true that you see the "object" you see than the fact that you see a chair. Altho you do not see everything when you look at this chair(that is what you see not really a chair) only what your senses allow you to see, this can again keep you from seeing the most real truth(as your senses don't see everything). But we do have tools that I believe in a way enhance our senses that again makes us see more that again puts us closer to the "truth", at least what I will want to describe as truth, altho I don't see truth as truly true.
But of course it is convenient for a society to have a concept on what truth is, what war is, what a chair is. But even tho we have these convenient concepts/categories, they don't become truths. This may seem a bit paradoxical but as I think truth is just a humanly invented concept, truth is not really truth. But if the questions was what shall you define as truth, that may be much harder altho perhaps I managed to touch this matter a little bit while I started typing away.
To summarize
1. Any definition of truth can not be true as language in istelf can never be true.
2. What you see is closer to the truth, but our senses don't describe something perfectly.
