KK thesis

The KK thesis or KK principle (also known as epistemic transparency or positive introspection) is a principle of epistemic logic which states that "If you know that P is the case then you know that you know that P is the case." This means that one cannot know that P is, if one does not know whether one's knowledge of P is correct. Its application in science can be expressed in the way that it must not only justify its knowledge claims but it must also justify its method of justifying. The principle is also described as knowledge-reflexivity contention.
