Question:
Why do people say truth is relative and that there is no absolute statement when that statement inself contradicts their claim?
Perhaps because people mix "truth" with "fact". Truth is a subjective concept, wherein "fact" is an objective observation of a particular result, or action.
For example when someone states "this will happen". That is considered conjecture. Depending upon how well one knows the one issuing the statement determines how much merit the listener will give to the "promise" made by the issuer of such a statement. That is truth, or the makings of such.
When someone states "this has happened". That is considered observation, particularly if it can be verified by a third party. One does not have to believe the issuer if the "fact" can be verified, but in repose, the fact does cause the witness to believe the issuer.
He tells the truth, because the facts prove he has done so...
Let us look at this another way. The Bible is called the Truth. However, the bible's truth is based in great part on "facts" occuring and being observed, so as to prove the validity of the Bible's promises. This is where faith comes in.
I believe the bible to be true, because in the past it has been proven true or factual. So, by faith, I take the future actions as described in the Bible to be true as well. It's kind of like choosing stocks and bonds. Christians are betting everything on future prospects, based on past performance...
Relativism is required just as absolute boundries are required. Black and white provides contrast, shades of gray provide reality.
Life isn't a fixed cartoon. It is a painting or drawing with depth and shadow.
