Can the truth contradict itself?

[democracy]

We have often heard the statement that "Truth cannot contradict itself." What reasons are there for anyone to accept or reject this proposition? BTW, is this a definition or an axiom? Is it a self-evident truth, as they say? Is it something that we cannot argue against? Why?

Is this statement "THE TRUTH" that we have all been looking for? Then why proceed any further?

If this is a definition, it seems like it violates the rules of definition in that it is self-reflective. The statement could be rendered thus: "Truth does not contradict the truth."

To apply strict logic to our inquiry, if this is not a self-evident truth, then what premise is this proposition founded upon?
