Armstrong presents a response to Colin Radford's modified version of the "unconfident examinee" example. A student is asked when Queen Elizabeth I died, and he hesitatingly answers "1603" and exhibits no confidence in his answer. He has forgotten that at some point previously, he studied English history. Radford presents this as an example of knowledge without belief. But Armstrong differs on this: the unconfident examinee has a belief that Queen Elizabeth I died in 1603, he knows that she died in 1603, but he does not "know that he knows". Armstrong rejects the KK Principle—that to know some thing "p", one must know that one knows "p". Armstrong's rejection of the KK Principle is consistent with his wider externalist project.
