Paul-Muadib was prescient in the
Dune chronicles, which explore the inherent problems with and effects of predicting the future with any
accuracy.
If you know your future, are you liberated from making the wrong decisions or are you condemned to stagnation and living out the dream in your head?
Does the very act of prescience itself create the future, or is it purely descriptive?
Is the prescient vision totally objective or highly personal, and if so what value can one place on it?
If someone prescient sees a new invention and then goes to create it what is to separate them from ordinary inventors who "see" their inventions in the setting of the future?
If one knew that one's future contained nothing but suffering, would one be able to kill themselves to escape?
And so on.
It might be interesting to study what so called psychics have to say on these issues.
