Bultmann: Impenetrable Nature
Rudolf Bultmann believes nature is a closed system of cause & effect, into which not even God can break.
He alleges that science has proved this; but how can science know that the universe is a closed system?
Science does not know what is going on below the level of quarks, beyond the universe, or before the big bang.  In regard to the future, it even has trouble predicting the weather.
