In the instance of Otto, there is no confirmation that he is the one who authored the information in the book. Otto is shown to only know that his known information exists in his notebook, however this situation does not explain how he knows this. If he did not retain the memory of the notebook containing what he knows he cannot be sure that he truly knows what he knows based on the content of the notebook. Even then we would have to question how he would. Being unable to see the knowledge / mental processes of Inga shows that she has retained the information and actually knows it, she can pull out the information if needed, and is aware that she can, whereas Otto has to consult a notebook which he may or may not have written in. If Otto were to lose his notebook the information stored in it would no longer be accessible to him. Therefore, his knowledge or memory does not exist without him having the notebook. One may argue that Inga could be in a similar situation when she is drunk, but the memory is still stored internally and if need she would could still pull out the information because it is still stored in her head and readily available if she so desired. For Otto, even if he desired for the knowledge he cannot access the info then Clark and Chalmers cannot argue that he knows
