Abstract

On First view there seem to be many possible instances of knowers who lack knowledge of their knowledge. A self-deceiver seems capable of knowing his own faults without knowing that he knows them. A philosopher seems capable of knowing that there are physical objects around him without knowing that he has such knowledge. Deep-rooted insecurity seems capable of preventing a mathematician from knowing that he has just made a genuine discovery. A child seems capable of acquiring knowledge before acquiring the concept ‘knowledge’ and hence before being able to know that he knows.
