He Who Was Not

[Patrick]

The only thing that is unconsidered perception is something that has not been encountered by consciousness.

I think you're confusing awareness with consideration.
It is prior experience which affords the awareness which then enables consideration.

The prior experience also provides the depth and breadth of awareness which enables all manner of thought (including intuitive perception, empathy, gnosis).

Indeed, when someone suggests one is 'considerate' in some circumstance, it is because the 'considerate' individual had the prior experience necessary to accept and to appreciate (to sympathize) what is involved.

Then this planet will have made us very 'considerate' towards a great many circumstances.
