Actually the epistemic skeptic would claim that no one can obtain knowledge and by my measure they are correct. The best that anyone can do is form a justified true belief- not knowledge. Knowledge requires absolute universal observation and of course this is impossible via DesCartes' "madman deceiving" principle.

Not only this, but in order to even form a justified true belief one must escape the infinite regression problem that we find in foundationalist claims.
