Objective truth isn't something you can know, but it's a destination that must exist for pursuit of knowledge/curiosity to have any meaning.

With contradictions you know what is not true, and through knowing what is not true, you can approach what is true. Truth is expressed in consistency, not completeness.

That's why anyone should be extremely suspicious of anyone who is not, or doesn't care about, being internally consistent.
