A Post About Truth

Sound familiar? Probably because last year I wrote a blog with a very similar title. But, in that case, I was going a slightly different direction. That blog was more about speaking up. Not so much about what truth really is, how to find it, or how to know it when you see it, but more about saying what you really feel, popular or (far more likely) not.
This is a blog about truth itself.
So...the inevitable question...what is truth?
