All knowledge is intrinsically valid. One can falsify a judgement by experience which is contradictory to it, but one can never completely verify a judgement by external means.
All knowledge acquired through the various pramanas [means of valid knowledge] is valid in its own proper sphere, but insofar as it is subject to contradiction by another qualitatively different kind of experience it is necessarily "relative" knowledge. Brahman-knowledge is alone incapable of contradiction.
There definitely are trends of similarity between these two statements and the statements of Godel's incompleteness theorem from logic.
I am not sure if these are general inferences that the authors make, or have translated them from definite sources in Vedanta. Yet to verify.
