Muad'Dib gave us a particular kind of knowledge about prophetic insight, about
the behavior which surrounds such insight and its influence upon events which
are seen to be "on line." (That is, events which are set to occur in a related
system which the prophet reveals and interprets.) As has been noted elsewhere,
such insight operates as a peculiar trap for the prophet himself. He can become
the victim of what he knows -- which is a relatively common human failing. The
danger is that those who predict real events may overtook the polarizing effect
brought about by overindulgence in their own truth. They tend to forget that
nothing in a polarized universe can exist without its opposite being present.
