 As many have pointed out, the result of the weaker version (3a) does not imply the result of the stronger version (3b). That a person has incomplete knowledge about a certain topic does not imply without further assumptions that there is some specific fact she does not have knowledge of. The example of knowledge about oneself (de se knowledge) may illustrate the general point. Let us suppose that John, who is at t in Amsterdam, does not know that he is now in Amsterdam (if asked about his present location he would assert “I am now in Venice”). John’s knowledge concerning the present location of people is incomplete. He lacks a specific locating piece of de se knowledge. Still, there need not be any fact concerning the location of people that John does not have knowledge of. It does not follow from the description of the case that John does not have knowledge of the fact that John is in Amsterdam. John may well know that John is in Amsterdam but, having forgotten that he is himself John, he may fail to conclude that he is now in Amsterdam. If John finally learns that he is in Amsterdam, he does not thereby learn a new fact – or so many philosophers would insist – he gains new knowledge of a fact that he already knew in a different way.
