The only way I can imagine that this is possible is the following: No matter how it works, it would require all events that started from at least the Big Bang onward to be in some way pre-determined (why does my Firefox spellcheck not know the word "pre-determined" and offers me "pee-determined" instead?). In other words, we would all be living in a sort of dimension that is actually separate from the dimension in which events take place. Now I know that time is considered the Fourth Dimension, but that does not exactly help solve the problem. It would require us in the sense of conscient beings to exist parallel to us as material beings. Even if I take this to be a scientific manifestation of the concept of a soul, it would nevertheless require us to be able to take influence on our actions and be incapable of taking this influence. That's a paradox. The only way of solving this problem is to assume that we are in fact incapable of actually performing an action, but that we are living in the belief that we are capable. But that only solves part of the problem. If clairvoyance were to exist, it would require the frontiers between both dimensions to be porous, so that certain individuals knowingly or unknowingly possess the capability to peek into the other dimension at random or determined points. Would this not mean that in our spiritual dimension, we had the capability of moving around freely independent of our manifestations in the material world? Maybe we could interpret out-of-body experiences and the like in this manner.
