Cause. A little over thirty years ago the modern quantum theory had its beginning in the mathematical work of Heisenberg and Schroedinger. The indeterminancy principle of Heisenberg was the basis for much writing at that time to the effect that free will was again restored to man. The mechanistic world of Newton was challenged. Because this mechanization was supposed to apply to all things in creation, even to man himself, it was thought by some to mean that there was a predestination in all things. However, as time went on it was gradually realized that entirely too many things were supposed without foundation, so that now we hear very little of the relation of indeterminancy and free will.
