Isn't truth a funny word?  Most of us appreciate it, most of us desire it. Very few of us, however, can define it.  Philosophers tell us there are essentially two ways of looking at truth.  The correspondence theory suggests that truth is simply that which corresponds to reality.  While this seems logical enough, it raises other questions:  how do we know what is real and how do we therefore know what corresponds to it?  Taking a slightly different tack, the coherence theory holds that truth is the sum total of what seems apparent, logical, and right.  Truth is not fixed but is rather what appears to be most correct based on the prevailing evidence.  Yet how do we decide what is most correct and right?
     Though I see virtue in both perspectives, I mention them to make a larger point:  the necessity of truth.  We need truth to be truth.  Otherwise, we became like the protagonist of Ernest Hemingway's Farewell to Arms, who, in the final scene of the novel, after seeing his wife die giving birth to his child, then seeing the child die, too, "put on his hat and walked into the rain."
     Unless we let truth be truth, we will be ever walking, too.
