02 Second Order/Readability Conditions/Visibility
Visibility
Visibility names the condition through which presented distinction becomes readable. Where visible carries the relational role of presented distinction, visibility names the produced read — the condition in which what is presented is available to be taken up into evaluation. Visibility is not mere presence; it names presence held enough to be read within the current scope.

Read
Visibility becomes recognisable where presented distinction can be taken up into evaluation — where what is there can be read rather than merely present.
