Two man are present to see the same event. But each see�s it a different way. Which version of the event is the truth or is the answer there is no
truth.
What one of the men sees may be true. What the other sees may be true. So they can both know part of the truth.
If they disagree on what they have seen, and what they both say cannot be true, then one or both of them is being untrue, consciously or
unconsciously.
There is a whole, absolute, full colour, cinemascope truth to which we are only ever partially exposed.
