You don't seem to understand that perspectivism does not depend on any human holding any view in particular. That doesn't matter one way or another. The point is that there are different possible ways of looking at things, and no provable way either to exclude possibilities or finally fix on ultimate answers. Realising this is so vital in so very many respects that it is a point worth making in different contexts.
There are many different possible ways to view perspectivism, but acceptance is the only correct way.
