Reply #4: Not identical to truthful, and not quite as pragmatism based as useful. [View All]

Basically, truth is close to, but not, an end to itself.

This is all running with some views on cognition already inherent, basically, I am saying that our little minds have not the time to work out everything for ourselves. Sometimes a practical approximation is good enough.

For instance, we may not be able to hold something still, but that does not stop welders or surgeons.

So validity is part 'closeness to the truth' and part 'reason for making such an approximation to the truth'.

If this makes no sense, I will rewrite it soon and am currently writing at very late in the night/morning.
