Then there is long sight and short sight and medium sight.

• There are some who can see far beyond, or long before events,
• and there is the person who only sees what is immediately before him and what is next to him; he sees nothing of what is behind him. His influence reaches only as far as the thing that is just beside him, and it is that which influences him.
• But there is another person who reasons about what he sees; his can be called medium sight. He reasons about it as far as his reason allows. He cannot see beyond his reasoning; he goes so far and no further.
