A complete understanding of reality.
My question: What do you mean by truth?
Your answer: A complete understanding of reality.
Then you know no truth?
I doubt you claim to have “complete understanding of reality,” but do you claim you therefore do not know anything that is true?
It is not necessary to know everything about everything to know many true things. The term for all that one knows that is true is “truth.” When one swears to tell the truth, the whole truth and nothing but the truth, they are not swearing to explain everything there is to know (understand) about reality, are they? Does the word truth in that swearing then mean nothing?

I wouldn't describe it that way. Such a thing is only possible from God's "point of view."
