The reason I am ambiguous about truth is that in reality, the occasions where we master complete information - and would hence be able to determine the absolute truth, are scarce. This means that when we bandy around terms like truth or fact in real life, we are actually talking more about a perception based on a quantity of information -which is itself perhaps not accurate and hence unfounded.

This has completey gone over into the territory of the current thread "a lie", but anyhoo.
In any situation where one or more of the parties involved has incomplete information that still does not make there reasoning or beliefs true for whatever they are doing or thinking.

Some years back we would use asbestos to fireproof a house because we had incomplete information we felt it had no health risk this was still wrong even though we did not know it.
