 Chalmers (2002, 2012: chap. 2), for instance, defends the idea that given enough qualitative information about the world we could in principle know the truth value of any claim. More specifically, his scrutability thesis says, if \(D\) is a complete qualitative description of the world, then for all \(T\), it is knowable a priori that \(D\) (materially) implies \(T\). Importantly, the knowability paradox does not threaten the claim that true Fitch-conjunctions are derivable a priori from a complete description of the world.
