By your phrase,
"human witness testimony," to which are you referring: 1)
truth or 2)
falsehood?
Which do you mean?
- "Well, that's the trouble with reliance of [truth] isn't it?"
- "Well, that's the trouble with reliance of [falsehood] isn't it?"
Oh, of course...back before mankind was blessed with the counsel of sages such as yourself!
By
"ascertained" do you just mean
known?
When you know that what an accuser is telling is the truth, it's very easy to know by inference therefrom that he/she is telling the truth.
When you know that what an accuser is telling is not the truth, it's very easy to know by inference therefrom that he/she is not telling the truth.
