We all wrestle with truth.  Many of us believe it to be relative, many of us consider it to be absolute.  And many more believe it to be irrelevant.  Underlying this debate is a more fundamental, no pun intended, truth, that is, we all come to what we consider to be truth on the basis of our assumptions.  We construct what we believe to be true, or at least credible, according to how we see the world.  If we are religious, we might say that truth is enshrined in God.  If we are not religious, we may say that truth is either irrelevant or that it is what we decide it should be.
     So perhaps it is a question of authority.  By whose authority do we decide what is truth?  It is here that we enter shaky grounds.  In ourselves, we cannot grasp, really, what is "true".  How do we know when all on which we have to go is our perception?  On the other hand, even if we believe in God or some sort of transcendent divine, we still cannot grasp the "true".  We're finite.  Either way, we are dependent on what we do not, and may never know to enable us to find or decide what is real and true.
     Hence, we can view what is true and what is truth as works in progress, works whose completion we have not yet seen.  As the apostle Paul remarks in 1 Corinthians 13, "We walk in a riddle, our knowledge incomplete . . . but one day we will know fully, just as we are fully known."  To know what is real and true means admitting that it is not ours, tiny and fragile beings that we are, to know fully.
