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

• There are some who can see far beyond, far back, or long before things happen. These also are forms of sight.
• Another person only sees what is immediately before him, what is next to him, and sees nothing of what is behind him. His influence is limited, because everything that stands next to him influences him; he cannot see far behind, nor can he see far before him.
• There is another person who reasons about what he sees; this is 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.
