http://en.wikipedia.org/wiki/Truth
A rather extensive encyclopedia article detailing what I am speaking of. This is one of the first lessons taught in Philosophy 101.
***
If I would give you the name of the place where I live as my residence, I would be telling the truth.
Let's say, for the sake of argument, that you live at 101 Farmer's lane. That is what you know your address to be, that is your truth. I knew that property when Farmer Brown and his wife and family used to farm that property years ago. I still think of it as a part of Brown's farm. That is my reality and my truth. No less true than your truth. Provided of course, that we view truth as relative. In point of fact, neither of us is completely true, because that land was know by others by different names and uses etc long before farmer Brown came along, and that land will be known by still others for different reasons long after you have moved on and your grandkids have grandkids. Neither of us has the whole, complete objective truth.
The closest to objective truth about this property that either one of us can attain, is the geographic coordinates, longitude by latitude (or is it the other way?). That would be the only thing that could conceivably in this example serve as objective, irrefutable and undeniable truth to not only you and I, but to any and everyone who has any concern about this property. With the caveat that they must understand geographic coordinates, without which "the truth" is of no use to them.
I hope this helps.
Probably better under the philosophy section, but since it was asked...
