What is Truth?

I perceive truth exists. I know things such as 1 + 1 = 2. This is truth for the constraints in which I've given it. Unfortunately, a mathematician's constraints might note the lack of precision on my 1 and say quite honestly that 1 + 1 could be 3. While this is not true for the majority of people, this is indeed quite possible since I did not specify 1.0 + 1.0 = 2.0. Truth then does still exist, only our perceptions of it differ given our constraints.

Of course, this is where conversation usually ends. I know that 1 + 1 = 2 and therefore you're an ignoramus for thinking otherwise and not listening to my cleverly laid-out logic to express so. Yet on the other hand, the mathematician would say the same thing. If only things were as simple as listening to another point of view though. Quite often, it seems that even despite listening and getting the words out there, truth is still not accepted due to built-in prejudice and underlying myths. Or then again, perhaps they are my own prejudice and myth?

I'm one to take pride in my love of truth. I despise untruthfulness. Things are complicated enough without people lying about every little thing. Yet everyone who has uttered these exact same sentiments appears to differ with me on some 'obvious' truth. Do we so delude ourselves? Do I delude myself the same way? Surely, others will gladly say so, yet I couldn't possibly believe it. I believe quite strongly that I am willing to listen to reason and truly acknowledge truth. Does that mean others are simply liars for saying similar yet not coming to my conclusions? I can't really say. It's impossible for me to know what is in their brain. It seems they are convinced in and of themselves, yet so clearly (to me) they are wrong from an undeniable stance of logic. Perhaps I am the same to them.

If we are so capable of feeling absolute truth within us when indeed we are not correct, then how can anyone ever fully comprehend truth? Truth must indeed exist, but how can we know it? Even if the universe were a parallel of all options such that all things were true at once and all things were false at once, would that not still be the truth? One cannot say, "The truth is that truth does not exist." One would have just made a statement of truth such that, if true, would nullify itself. Although, perhaps it simply needs more constraints. For example, "Truth does not exist beyond this fact." But, of course, even that truth would have sub-truths derived from it: "Well, if truth does not exist and all things are conglomerated potentials, then I should be able to move things with my mind!" Immediately, this statement can be true or false. Perhaps in my dimension, this is not true. Of course, that means its negation is indeed true.

Logic cannot be destroyed. It must exist. Truth must exist. The question simply becomes, how can we know it? How can we know the bounds? How can we know that 1 is 1.0 and not 1.4 such that our logic 1 + 1 = 2 is correct? The truth is out there, and many people 'know' it. In fact, many people know they know it. But that, of course, does not validate their knowledge. They very well might be deluded despite their grandest convictions. I now know that they don't 'know they know it.' Or do I...?
