It is only pseudo-knowledge which becomes falsified according to this view, then the theory of intrinsic validity becomes superfluous if not refutable. It is difficult to maintain that knowledge as such is true and the criteria cannot any more prove its truth. If what is not true, cannot be said to be known, the theory of intrinsic validity of knowledge becomes paradoxical in some sense. The notion of truth would appear trivial on this view and problem of illusory knowledge becomes inexplicable.
Nyāya philosophers, therefore, do not seem to be in favour of the theory of intrinsic validity of knowledge. However, there is difference of opinion between the ancient
