> there are only human points of views grounded in human cognition and human interests.

“Only”? No.

The entire point of having a scientific approach, an ever longer list of ways to weed out mistakes and misperceptions, is that raw human cognition can be improved upon.

Repeatable results, independently reproduced results, peer review, control elements, effect isolation, … the list is actually very long.

Not every one of the methods we have collected applies to every step in knowledge, but every step we take can be validated by as many of them as apply.

And new ways of falsifying false conclusions continue to accumulate.
