How Do We Perceive Truth?

Let me first be clear, I believe in absolute truth.  That means that two contradicting "facts", even if the contradiction is ever so slight, cannot both be true at the same time.  I think there's lots of really simple logic that proves that as a truth.

However....  here's some interesting things to ponder related to that TRUTH.

Is it possible for two people, viewing the same truth, to interpret what they're seeing and experiencing in different ways?  Could both people provide an accurate description of what they see but the two descriptions still vary?

 I suppose a big difference might be what the subject under consideration is.  If it's physical and measureable versus something that is not.

For an oversimplified example from a natural science perspective consider how we interpret colors.  You might put the same blue piece of paper in front of two people, but get two different descriptions.  One might say they see a blue piece of paper.  The other might be convinced what they are seeing is a purple piece of paper.  You might be convinced they are both wrong because it's green!   Consider this, what if from the very first time you were learning your colors everyone around you taught you that green was actually red?  If you never heard or saw differently then you would believe that to be true. 
     Now, because you can measure color, you can actually determine truth.  Blue is technically defined as the way our eyes perceive light wavelengths between 440 - 490 Nanometres.  So in the example above you could actually measure the wavelength and prove what color the paper is.  From a day to day standpoint we have arguments about things like this all the time.  Consider sports... we argue about whether the person actually kept their feet within the boundaries, or wether the ball went over the line.  Technically speaking it could be proven precisely what happened.
  
It's not this kind of absolute truth that is so perplexing to me....   the kind that is more perplexing to me is the truth that we can't measure, at least not here on this earth.  Does God exist?  What is right and wrong?  Was Jesus really God?  Is there really a spiritual world?  Do we have souls? and the list goes on.

I suppose that is where faith comes in to play.  The fact that I do believe there is an absolute truth.  The fact that I do believe that truth can be known.  I'm left to take all my observations, interpret those observations, and conclude what I believe to be the truth.  The "certainty" that I have in those truths is really all about faith.

Hebrews 11:1 - "Faith is the confidence that what we hope for will actually happen; it gives us assurance about things we cannot see." (NLT)
